All four patients received their spinals within three hours of each other by the same anesthesiologist, who had no way of detecting the error made by the clinical pharmacy. This led to two people becoming paraplegic, one losing significant function in their legs, and one being placed on ECMO or a heart-lung bypass machine. Timeline Technician #1 initially selected the correct mepivacaine 2% vial and placed it on a work surface. 20 min later, the technician scanned and photographed that correct vial and then determined that another vial was needed. One vial would have enough volume for five syringes, but the order called for six syringes, and so another vial was required.The technician retrieved potassium phosphate from a different bin that was stored close by the mepivacaine bin. Notably, the vials were lookalike drugs with extremely similar size, contents, and labelling down to the displayed names being similar. When the additional vial of potassium phosphate would not scan, the technician returned to the storage area, placed the two vials (including the correct mepivacaine 2% vial) into the potassium-phosphate bin, and retrieved two more potassium-phosphate vials.Technician #1 bypassed the scanning of these two vials, photographed the two vials of potassium phosphate, and placed them along with five empty syringes, and six mepivacaine labels into a bin that was passed into the mixing room.Technician #2, supervised by Technician #3, filled five syringes with 4 mL each and labelled them mepivacaine 2%. She also took photographs which included the potassium-phosphate vials. Technician #3 looked briefly into the medication bin that was passed into the mixing room and then sat down.Pharmacist #1 approved the preparation electronically. Approximately 29 seconds elapsed during the computer review. The pharmacist did not detect that both photographs showed vials of potassium phosphate rather than mepivacaine.James Reason’s Swiss Cheese Model is used to simplify a complex process where harms occur due to ‘holes’ in the barriers or defences in depth. We do this so that we can properly investigate and improve our safety systems, but it is not where the inquiry ends – it is the beginning of the investigation.  What if this was simply a ‘bad’ hospital, pharmacy, or ‘bad apples’? Having four ‘bad apples’ is extremely unlikely. This is almost certainly not isolated to a single organization. Even the strongest, most safety-minded pharmacies and hospitals can find learning points here. It is that mindset – that systems can always be improved – that has permitted other safety-critical industries to make such significant safety improvements over the past several decades. Lessons to learn Latent conditions must be continually rooted out.Segregation of high alert medications is paramount.Leadership walkthroughs are an important way to ensure that written policies are actually implemented.Human factors should be taught to all front-line medical workers, including models and policies that consider how stress and fatigue increase the likelihood of errors being made and not being trapped.There are tools to examine and strengthen the workplace culture.The use of technology (scanning the medication vials) is only one barrier. In this case, the barrier can be strengthened (likely by requiring a pharmacist-controlled resolution or some other check such as entering the drug ID number), but we also see what the investigators in this incident call an overreliance on technology.In upcoming episodes, Dr. Ken Catchpole talks about the use of icons (such as the biohazard symbol + colour coding), so that medication types can be easily identified from a distance.Medications could be colour coded with dye, as aviation fuel is. People-focused solutions (training, adherence to SOPs such as telling workers to ‘read the label’ or ‘look at the pictures’) are the least effective. However, to the degree that this barrier can be improved, consideration should be given to examining the SOPs: what procedures are trained, are they actually used in practice, and are frontline workers regularly monitored for adherence to SOPs.Additionally barriers for error-critical medications such as intrathecal medications. In this case, the hospital introduced an additional crosschecking of work for all intrathecal medications.Reconciliation of the amount of medication orders vs filled by the pharmacy.Revision of the regulatory oversight of clinical pharmacies to help prevent recurrence should be considered.Other pharmacy medication errors that have resulted in death: In 2006, 1.5 year old Emily Jerry in the US died due to a pharmacy technician inappropriately preparing her chemotherapy. The pharmacist in that case was held criminally responsible for the death.In 2011 in the US, an infant died from an incorrectly compounded parenteral nutrition. Andrew Sheldrick, age 8, died in Ontario, Canada in March 2016. Andrew’s medication was incorrectly compounded.Other resources APSF YouTube Video (10 min) on this incidentNews release update from the subject hospitalPractice Patient SafetyJames Reason’s Culpability Models (see our website for diagrams)The Hierarchy of Intervention Effectiveness DiagramSafety intervention worth mentioning: Tennessee Health Facilities Report  Who can do what tomorrow?  Policymaker / government: Advocate for an aviation-style national medical investigatory body like England’s HSSIB and Norway’s UKOM, with independence from the regulator so that the entire system can be strengthened where necessary.Hospital CEO / Department Head: Assess the organization’s safety culture using the available tools and monitor for adherence to SOPs.

They are evaluated on their technical and non-technical skills. Flight tests include scenario-based oral exams similar to physician board exams.Currently pilot training programs in Canada are starting to shift from modular or block-style training (private license, adding night and instrument ratings, etc.) to a more integrated philosophy to train multi-crew airline pilots from day one. A Pilot Proficiency Check (PPC) acts as a type rating that is added onto an existing pilot license for a specific type of airplane. This happens roughly every six months and reviews both normal procedures and emergency procedures. Given the basics of CRM described above, pilots are marked based on four global points (effective, acceptable, poor, unacceptable) while examiners think about possible CRM elements including: Did they anticipate the threat? Do they make inquiries for more information? Do they consider downstream consequencesHow was the situational awareness? Did they communicate appropriately?How did they manage their workload?How did they get rid of distractions?Was the aim achieved?Errors are deemed as “critical," "major," or "minor," each with their own repercussions on the outcome of the flight test. The CRM framework allows us to trace back errors observed and trace back why they might have occurred.In aviation the Pilot Proficiency Check is a check on a specific aircraft where a line check is run by the airline to determine the safety and effectiveness of company-specific policies and procedures. Situational Awareness “We all have our own mental models about a certain situation, and if it is accurate, this means that we have good situational awareness."We may have fixation-induced loss of situational awareness through task saturation (e.g. intubation, troubleshooting landing gear)Captain Schuster imagines workload management in three buckets: information can be perceived, processed, and then acted upon. Each must be balanced to function well. Cooperation Cooperation: the ability to work effectively as a team. Cooperation begins in the formation of the team and considers the skills and attitudes of individual members. Basic conflict resolution techniques can aid in examining the root cause of errors. A debrief of the exercise is just as important as completing the full exercise in examining the components of CRM that failed and that were successful.Decision-making Decision-making includes identifying the problem, generating options for action, assessment of the risk, willingness to reassess the plan, and analysis of the outcome.Decision-making in aviation is most often evaluated in the debrief, where the examiner and the trainee discuss the thought processes of the trainee and hypothetical cases.  “The event in the simulator is the practice, the learning takes place in the debrief.”Leadership, Managerial Skills (and followship) Designated leadership (e.g. Captain) versus functional leadership (context-specific, depending on who has the most relevant experience)Followership: giving appropriate feedback at the appropriate time, asking questions if unsure, suggesting alternate courses of action (which requires good situational awareness).Authority gradient: if too steep, people will not speak up when necessary. If too flat or out of balance, there is a risk of failure of leadership.Good leaders use functional leadership to achieve goals. (e.g., the First Officer has more experience at a particular airport).Good followers will use graduated assertiveness when necessary (e.g., the Probing, Alerting, Challenge, Emergency (PACE) model described in Episodes 3 & 4).Leadership on the flight deck incorporates planning and coordination. For example, in November, Captain Schuster will ask his First Officer, “Have you needed to de-ice yet this season? Have you had a chance to look over the checklist in advance so there aren’t any surprises?” Workload management is also a part of leadership, where the leader assesses the situation and then delegates appropriate tasks with clear communication while ensuring they are not task saturated.Appropriate feedback to trainees and to their training unit allows both individual and system-wide deficits to be studied and improved on.  CRM in medicine The concept of a Pilot/Physician Proficiency Check (PPC) where a physician must recertify their proficiency at normal and emergency procedures, exists in certification courses such as ACLS, ATLS, and NRP. We do not have specialty or institution-wide proficiency checks after the specialty exams.Medicine remains very individual-focused as opposed to team-focused (e.g. one doctor runs the code and must think of the next steps of action, whereas in a flight emergency the captain often gives control of the aircraft to the first officer, leaving them free to think about next steps). Medicine has started to recognize the importance of debriefing after resuscitation or critical events. Other Resources TC Approved Check Pilot Manual. Re-enactment of a check flight and assessment of CRM (YouTube 19 mins). The issue starts in the briefing where the First Officer lacks trust due to the Captain’s apparent lack of knowledge. This leads to an in-flight emergency that results from a poorly managed abnormal event: an electrical problem. During the running of the checklist, no one is flying the airplane (monitoring the airspeed, which was previously too fast and the thrust levers retarded), the stick shaker activates, indicating an aerodynamic stall is imminent and the crew recovers from the Undesired Aircraft State (UAS). During the debrief, we see the learning take place.Safety Intervention Worth Mentioning: University of Texas Human Factors Research Project: Threat and Error Management.

Trauma: Who Cares? (2007)Similar to the Transportation Safety Board (for aviation) watchlist, the NCEPOD has a list of “Common Themes” which highlight key themes in quality of patient careDr. Mason’s key suggestions in advocating for the creation of something similar to NCEPOD in Canada: Highlight how the work is directly relevant to patients while engaging clinicians as opposed to punishing them. Acts as a protective mechanism for the healthcare institution.  Emphasizes clinicians volunteering their time to reflect on cases of other clinicians and generate insights into how care could have been improved Safety Intervention Worth Mentioning: NCEPOD Reports – see below. NCEPOD Audit Tools for various hospital departments.  Random Recommendations Dr. Mason: “Try to find the lightheartedness where you can.”Adam: Watch the World Cup.

It was subsequently updated in 2024 to the current edition with a stronger focus on communication, transition planning, and follow-up.  Common Thread: health care often does not fail due to technical proficiency, rather, it fails due to lack of teamwork, weak communication, poor documentation, and delayed recognition of deterioration.The NCEPOD may serve as a useful guide for healthcare workers and policymakers looking for ways to optimize patient safety and flow through the institution.  Safety Intervention Worth Mentioning: NCEPOD reports The National Confidential Enquiry into Patient Outcomes and Death (NCEPOD) - Common Themes 2024 Report Random recommendations Adam: CBC’s The Expert Witness from Uncover and watch out for CBC’s See You in Court (Season 2) podcast.Amir: Journal for both positive and negative emotions in your life

Send us Fan Mail Show notes Colon Cancer ScreeningColon cancer screening is conducted in Ontario with the Fecal Immunochemical Test (FIT). The test detects microscopic blood in the stool.An abnormal FIT leads to a colonoscopy which can detect colon cancer or polyps before they turn into cancer.Screening testsA screening test is used to test populations that are at average risk for a disease. It is difficult to design a screening test, because they have criteria.A good screening test targets an important condition with a detectable preclinical phase, accurately identifies disease, is safe and acceptable, leads to an effective intervention, and (most importantly) improves meaningful patient outcomes while minimizing harms such as false positives, overdiagnosis, and unnecessary treatment.Changes to the FITOn July 1, 2026, the Ontario government lowered the eligibility age for people to access publicly funded colorectal cancer screening from 50 to 45.At the same time, they change labs from LifeLabs to In-Common Laboratories (ICL), which did not have the same ability to communicate the results digitally, as was previously done.The lack of digital communication was replaced with faxed results. This means that:Results do not integrate with family physicians’ digital inboxes;Electronics flags and red highlighting of abnormal results are not available;Front-office staff, which are typically not involved in digital communications, must manually review the results;Digital reminders in physicians’ Electronic Medical Records (EMRs) are not updates - a considerable issue since many family physicians have over 2000 patients each. This increases the risk of missed future screening;Increased risk of delayed or missed diagnosis of colon cancer, which ultimately increases the risk of morbidity and mortality (disease and death) from colon cancer in Ontario;Batch faxes: faxes with multiple patients on the same page, which increases the risk of communication errors; andPatients being informed by letter of possible colon cancer before their physicians have been informed.The SGFP Advocacy CampaignIn addition to the above, the timeline was extremely short: primary care partners were not informed until 70 days before the go-live date.That digital integration was not made a condition of the lab contract and how this is a structural gap in program design as well as the lack of primary care input at the design level.That this is at odds with Ontario Health’s own Patients Before Paperwork commitment. In that Ontario Health initiative, Ontario, in 2023 made a major commitment to “axe the fax,” including eReferral and centralized intake / care coordination.Ontario has said that to mitigate this risk, front-line office staff should be vigilant in looking for the faxes. This is another example of the medical system relying on front-line practitioners plugging the gaps in the system and how this contributes to physician burnout, which can deprive communities of an important resource.If Ontario’s healthcare system had a Safety Management System (SMS), a risk analysis would have been conductedAt a minimum a proper SMS that included proactive safety measures would have identified the risk that the transition created.In this case, the FIT test has not changed but more people are being screened, so an analysis of whether the increased risks of delayed and missed diagnosis were counterbalanced by overall less morbidity and mortality for screening more people a few months earlier, would have been conducted.This is a balancing of the risk of early implementation with poorer communication standards compared to the risks for those aged 45 to 49 who wouldn’t be screened until the proper communication standards had been achieved. The analysis would have to show that more lives / harm would be saved with early implementation compared to the number of lives lost.We saw an example of this kind of analysis conducted by the HSSIB in Ep 9 - Unintentionally Retained Surgical Sponges - Part II.Risk management in mature safety management systemsKey elements of risk management:identifying hazards (things that could cause harm) (e.g. poorer communication standards leading to increased risk of delayed or missed colon cancer diagnoses)assessing the risks (the likelihood of a hazard causing harm and how much harm may be caused) (e.g. estimate the number of delayed and missed diagnoses of colon cancer)putting in place risk controls as appropriate (e.g. delaying the transition until the same communication standards are in place)documenting the management decisionsreviewing the risk controls (an iterative process)Within risk management there is not an expectation to eliminate all risk, but to reduce risks to ‘as low as reasonably practicable’ (ALARP). This requires risk to be balanced with efficiency.“The decision process begins with a presumption that the risk reduction measure should be implemented. It would only be deemed reasonable not to implement the risk reduction measure if it would be ‘grossly disproportionate’ to the benefits that would be achieved. An extreme example is that spending £1m to prevent 5 staff suffering bruised knees would be considered grossly disproportionate”Meaning the government-of-the-day bears the onus to show that the risks and the costs were considered.Safety management systems improve efficiency and safetyA safety management system and risk analysis is not a hoop to jump through or a bureaucratic process: it is a process that guides decisions to make them not only safer, but more efficient, ultimately leading to cost savings.In this case, considerable time and expense has been required to mitigate the risks caused by the reversion to faxes. Many meetings, use of front-office staff, etc.For those unfortunate Ontarians that have delayed or missed colon cancers, the healthcare system will spend enormous sums of money caring for them. The costs of one colon cancer surgery on the system alone would likely pay for the time it would have taken to conduct a proper risk analysis, not to mention the agony and hardship for the family of that person.Dr. Barber wonders whether the current  system of issuing FITs to patients, rather than, for example, having them available at the pharmacy, would improve uptake of colon cancer screening.Safety Intervention Worth Mentioning: Section on General and Family Practice (SGFP) Advocacy CampaignsSection on General and Family Medicine website: SGFP.ca Chair’s Letters (how Adam and Amir first discovered this issue)Policy contentAdvocacy toolsWho can do what tomorrow?Policymaker / government / regulator: Take heed of the issues presented here and work quickly to at least restore the level of communication of FIT tests in Ontario to what it was previously.

Send us Fan Mail Show notes The Health Services Safety Investigations Body (HSSIB) investigates patient safety concerns in the UK. They are an independent body with the aim of making healthcare safer.Excellent care is one goal, but well-connected and easy to navigate care is an entirely different matter.In the current healthcare system, it is practitioners that are keeping people safe by filling in the cracks in the system, rather than the system helping to make it easy for practitioners to get it right, and harder for them to get it wrong.Dr. Benneyworth on behalf of the HSSIB notes the importance of meeting people who have been harmed by the system. Listening to patients is important, including if not especially after a bad outcome.The Stafford Hospital deaths was an inciting event for the creation of the HSSIB.A significant benefit of the HSSIB is that it has healthcare, human factors, and other industry expertise that is ready to investigate immediately, rather than waiting for a commission of inquiry to be stood up.Canada does not have a national healthcare system. What started as a social experiment in Saskatchewan with Tommy Douglas, became what we now know as the Canadian healthcare system because of a cost-sharing legislation (The Canada Health Act).As healthcare is mostly administered under the provinces, there is nothing stopping a province from creating a body like the HSSIB.Despite the HSSIB being a relatively new body, there is already evidence of its efficacy. For example, after the aortic dissection report, evidence suggests that approximately 300 more people a year are being identified as having an aortic dissection and are getting life-saving surgery.Just as some issues require a national response, there are likely issues that require a multinational response (e.g. medical devices, similar to how airplanes are subject to Airworthiness Directives / grounded for mandatory maintenance).The National Confidential Enquiry into Patient Outcomes and Deaths (NCEPOD) is an audit-based body that also helps improve patient safety.The HSSIB does a lot of work in observing how work is actually performed in healthcare (work as done, as opposed to work as imagined).Providing empathetic care can protect against burnout.As the HSSIB retained sponges report shows, by redesigning the system (e.g. RFID tagged sponges) we can improve patient safety, increase efficiency, and reduce costs all at the same time. Improved safety does not necessarily mean increased costs, in fact, in the HSSIB’s experience, the opposite is true - that the safest organizations are often the most efficient.OR / Resuscitation RecordersIn the sponges report, the HSSIB was not able to determine what happened in the reference event where sponges were left inside a patient. This is because the only evidence available was from the people’s memories of those events.The HSSIB did not turn their mind to recommending OR recorders.In aviation, the black boxes (Cockpit Voice Recorder and Flight Data Recorder) were invested to gather such evidence.Concerns raised regarding the potential use of OR recordersMedical culture (are we ready for them?);Patient privacy;Misuse of the data (i.e. for discipline); andCost of installation and maintenance.Adam’s rebuttal of these:Medical culture is informed by the use of technology and as the HSSIB gains a reputation for safety, a just culture emerges. Rather than wait for medical culture to change, we can change medical culture through the appropriate use of this technology (just as we did in aviation).Patient privacy: gain consent (as is currently done by the few organizations that currently use OR recorders) or anonymize.Misuse of the data (i.e. for discipline) - legislation and policies similar to what currently exists in aviation. Also, only the safety investigator and no one else can access the data; andCost of installation and maintenance: in terms of cost-benefit analysis, this is a low-cost for significant benefit.Safety Intervention Worth Mentioning: Health Services Safety Investigations Body (HSSIB) reports The Health Services Safety Investigations Body (HSSIB) (where you can subscribe to their mailing list)HSSIB Report: Retained swabs after invasive procedures (April 16, 2024)HSIB Report: Severe brain injury, early neonatal death and intrapartum stillbirth associated with larger babies and shoulder dystocia (April 19, 2021) Other resources The Stafford Hospital deaths was an inciting event for the creation of the HSSIB.The National Confidential Enquiry into Patient Outcomes and Deaths (NCEPOD) is an audit-based body that also helps improve patient safety.

Send us Fan Mail Show notes Risk management principles: Key elements of risk managementIdentifying hazards, or risk identificationThese are the things that could cause harm or problemsassessing the riskThe likelihood of a hazard causing harmPutting in place controls or making a decisionImplementation of solutions that lead to risk reduction or preventionDocumenting the management decisionsA recording of the findings and outcomes of your intervention; if you don’t measure it, it doesn't matterAllows you to keep track of efficacy of changesCyclical reviewCheck if old interventions are still valid or if there is a better way of risk management nowThere is not the expectation that all risk will be eliminated but the goal is to reduce the risk to “as low as reasonably practicable” (ALARP)The utility of this framing is that it helps set reasonable limits on the degree of intervention needed to address a problem. The example used in the report is “An extreme example is that spending £1m to prevent 5 staff suffering bruised knees would be considered grossly disproportionate”This allows us to frame successes as reductions in adverse events rather than a total elimination of some events that are unavoidableThe UK’s Health and safety executive, their national regulator for workplace health and safety actually sets a guideline for acceptable risk: death of one in a million per year for both workers and the publicThe utility of having this put out by a national board sets a benchmark for comparisonThe HSSIB performed some back-of-the-napkin math and found that in 2013 there were approximately 4.7 million surgeries conducted in the NHS per year. Then using the data of reported unintentional retained sponges, they found that the average was one incident every 270,115 surgeries. Since it was not known whether anyone had ever died of a retained sponge, they used a conservative estimate of 1 in 10 retained sponges resulting in death.This resulted in a “risk to life” (RtL) of 10mMany studies in the US showing they can reduce the number of retained sponges and improve the efficiency and effectiveness of the count, as well as reduce costs.Barcoding - swabs in and out, but must be scannedThe findings of the report A range of interrelated system factors (tools, technology, organisation, task, environment, and people) influence the reliability of the sponge count.The reconciliation process has not been formally analysed or designed using human factors expertise (where the interactions between people and other elements of the system in which they work are explored) or any other process design expertise.Other safety-critical industries assess and control risks to be ‘as low as reasonably practicable’ (ALARP), where there is not an expectation to eliminate all risk. These risk management principles have not been applied to the risk of swabs being unintentionally retained.There is no accountability framework, and it is unclear who owns the risk for retained swabs and reducing the risk for retained swab events to as low as reasonably practicable.Blame can be inappropriately placed on scrub nurses or surgeons when an item goes missing, rather than the reconciliation process being seen as a team activity and one that can be influenced by a wide range of interrelating factors.Staff and national organisations had varying views on the roles and responsibilities for swab reconciliation; limitations in training were identified.The investigation was told by various national organisations that there is a concern about removing Never Events from the NHS’s framework and how determining risk appetite (where it is accepted a level of harm will occur) will be perceived by the wider public.The design of swabs does not help staff to locate, identify, or track swabs during the reconciliation process.There are technologies and tools that could be used to improve the accuracy of the swab count; however, these have not been embedded into UK healthcare.The technology and tools have not been formally considered using risk management principles in terms of reducing the risk to as low as reasonably practicable, or how the technology could reduce other patient safety concerns while also supporting productivity and efficiency in healthcare. The Recommendations “HSSIB recommends that the Centre for Perioperative Care (CPOC) and Association for Perioperative Practice (AfPP) continue to work together with other key stakeholders to review, amend and embed the process and standards for the reconciliation of swabs ensuring it is robust. This review should utilise human factors expertise and user-centred design principles, to reduce the risk of retained swabs to as low as reasonably practicable. Any changes to either organisation’s processes should consider potential unintended consequences and the influence on other safety-critical tasks and include consideration of professional roles and responsibilities in relation to swab reconciliation.”“HSSIB recommends that NHS England develops a framework to assess whether risks, such as retained swabs, are reduced to an acceptable level. This will allow organisations to develop their risk strategies and document their risk acceptance criteria and tolerance.”“HSSIB recommends that the National Institute for Health and Care Research assesses the priority and feasibility of commissioning research to review the viability of implementing technology that could support reducing the risk of retained swabs. The review should balance patient safety, costs, benefits, design, implementation, and the various ways in which the technology could be used to reduce other patient safety concerns to as low as reasonably practicable.” HSSIB Safety Observations “Manufacturers of swabs can improve patient safety by facilitating better detection of retained swabs through user-centred design.”“The NHS can improve patient safety by ensuring procurement decisions about swabs are made on a risk-informed basis that incorporates evaluation trials and user-centred design processes in the design, manufacture and testing of products.”“Multidisciplinary team training can improve patient safety by increasing the understanding of team roles, responsibilities, teamwork, the interrelationships between the work system and people and ultimately improve the care of patients undergoing an invasive procedure.”“A user-centred evaluation of non-technical tools to aid the swab count can improve patient safety by helping national organisations and trusts assess whether their risk of retained swabs is as low as reasonably practicable.” Health Services Safety Investigations Body (HSSIB) reports HSSIB Report: Retained swabs after invasive procedures (April 16, 2024)HSSIB Interim Report - Retained swabs following invasive procedures: themes identified from a review of NHS serious incident reports (December 7, 2023)HSIB Legacy Report: Detection of retained vaginal swabs and tampons following childbirth (June 7, 2021) Random recommendations :  Amir: GardeningIt doesn’t have to be gardening but have a small plant or flower that you can take care of.

Send us Fan Mail Show notes The reference event: Helen’s CABGHelen had heart surgery (CABG x3 “triple bypass open heart surgery”).The day after the procedure, Helen had trouble breathing and a Chest X-Ray (CXR) taken for another reason, identified a retained sponge.She was taken back to the OR and had the sponge removed. As she was quite unstable, the decision was made not to X-ray her in the OR and to close her chest and stabilize her. At 7:30 pm, a CXR identified a second sponge in the same location as the first. The following morning, she had another surgery to remove the swab from her chest. A CXR performed in the OR showed no foreign objects.Helen was in the ICU for 7 days and was discharged 13 days after her final surgery to remove the second sponge. At home, Helen had ongoing health problems. Helen’s family referred the incident to the HSSIB.When the investigators first met Helen six months after the incident, she was visibly upset by what had happened and she reported she had received limited mental health support. According to the report, Helen continues to have health and wellbeing issues.”BackgroundInvestigation began: Sep 28, 2022.Interim report: Dec 7, 2023 (14 months later) highlighted common themes in 31 serious incident reports (investigations carried out by local healthcare trusts).Final report: Apr 16, 2024.Never EventsDefined as ‘patient safety incidents that are wholly preventable where guidance or safety recommendations that provide strong systemic protective barriers are available at national level and have been implemented by healthcare providers’ (NHS Improvement, 2018).” [emphasis added]Multiple UK reports call for Never Events to be renamed because the events described are not entirely preventable, there are not strong barriers available to prevent them, and by calling them Never Events, it invites stigma and shame and discourages reporting and thorough investigation.“The count” / reconciliationSponges are counted in a specific way, by two nurses, who must agree on the count before the sponges are usedAnalysis and findings regarding the reference event (Helen’s CABG)The HSSIB: “Limitations in the evidence meant it was not possible to identify precisely what happened during Helen’s surgery to result in two swabs being retained."It is curious that the first finding of this report is that the available evidence made it impossible to determine precisely what happened during Helen’s surgery, yet there is no mention of recording devices in the report. In aviation, they had to invent a robust means of recording what occurred in order to determine what happened and how to prevent future accidents. In this case, OR Black Boxes would almost certainly have provided the evidence needed. Patients continue to be placed at risk by the unavailability of this information.Factors affecting the sponge countresponsibility for swab counts (surgeon vs scrub nurse)communication of information about swabsSurgeons not informing scrub nurse when a sponge was insertedvisibility of swabsNot in direct line of sightSoaked with blood and therefore lacking contrast with surrounding tissueRadiopaque stripes appear similar to other lines on XR and when an XR is performed for another reason, no one is looking for a sponge.the make-up of the operating theatre teamWhen there is a change of nurses, the count wasn’t always being conducted between the outgoing and incoming nursesthe timing of the count and its confirmation at Sign Outthe type and duration of the surgical procedureprofessional culture and practiceSurgeons taking swabs directly from the nurse’s table without informing the nurse.distractions and interruptionscompeting tasks (counting while doing other tasks)time pressuretime of dayMore common in surgeries between 2 pm and 7 pm, raising concerns of fatigue (HSSIB noted further data are required here)clarity of policies and procedures - lack of clarity on specific times counts are to be performedThe report again identifies weaknesses in the level and quality of the evidence available in the investigation and finds that there may be other factors that affect the reliability of the count that could not be identified because of that. Factors affecting the detectability of the sponges in Helen’s chestSponges come with tails, but these were cut off before the sponges were used.Sponges absorb blood and then look like tissue.Sponges can be very deep in a cavity and be obscured from view by organs.Factors affecting the detectability of the sponges on x-rayThere were many other items visible on the CXR (tube, lines etc) making the sponges more difficult to detect.The clinicians were focused on other theories for Helen’s deterioration.Factors affecting detection of the second retained sponge Staff thought there was only one sponge.Helen was unstable and it was deemed unsafe to conduct an extensive search of the chest cavity or an X-ray.Analysis and findings of the wider investigationThe low frequency of retained foreign objects following invasive procedures indicates that the counting system is largely successful, however, counting items is not a strong systemic barrier.There is a tension between spending more time on something that seems to be largely working well (the count) and the need to be efficient with operating room time (or else harm comes to patients).HSSIB explicitly identifies the conflict that is present in frontline healthcare workers’ minds: ‘every minute that is spent attempting to improve a process that works most of the time is a minute of OR time that another patient cannot receive’The HSSIB resolves this tension by pointing out that while ‘Frontline workers generally operate under rules and procedures which provide a normative standard against which their behaviour can be judged. In contrast, designers, managers, and such generally operate with more degrees of freedom.” Meaning we may be able to design better sponges and use system measures rather than people-focused measures to reduce this risk without a tradeoff.OR Black Boxes & Medical Culture (Patreon-only)Safety intervention worth mentioning: The Hierarchy of Intervention Effectiveness (see diagram) In North America, medical culture places the emphasis on the frontline staff to get it right and when incidents are made known to staff, there is an expectation that that awareness should be sufficient to prevent it from recurring. This is as opposed to changing the working conditions, which is Professor James Reason’s main conclusions in his life’s work.In the interim report, the HSSIB refers to “The Hierarchy of Intervention Effectiveness” from Cefazzo and St-Cyr, 2012, which shows various interventions and their relative effectiveness.“The hierarchy is a tool for ranking the effectiveness of measures used to reduce the risk of a safety event. Measures that rely on people are considered to be less effective.”The solution is to change the working conditions Health Services Safety Investigations Body (HSSIB) reports HSSIB Report: Retained swabs after invasive procedures (April 16, 2024)HSSIB Interim Report - Retained swabs following invasive procedures: themes identified from a review of NHS serious incident reports (December 7, 2023)HSIB Legacy Report: Detection of retained vaginal swabs and tampons following childbirth (June 7, 2021)Other resources Willful Blindness by Margaret HeffernanSelective Attention Test (Simons & Chabris, 1999, YouTube) (1 min)Cognitive bias in diagnostic radiology (radiopaedia.org)Random recommendations Adam: Go see the RCAF Snowbirds! 2026 ScheduleSnowbirds to be grounded after the 2026 season until 2030 when they acquire new aircraft (CBC: May 19, 2026)Amir: Be a tourist in your own city

Send us Fan Mail Show notes Errors occur when a planned sequence of events fails to achieve its goal without an element of chance.Slips and lapses are absentmindedness.Trips and fumbles are maladroitness.Mistakes involve higher order cognitionMain classification of errors:Skill-based slipsRule-based mistakesKnowledge-based mistakesExamples of skill-based slips: putting cat food in the teapot, getting into the bath with your socks on, trying to open a door with the wrong key.Examples of rule-based mistakes: proceeding when it’s not your turn at the intersection (most driving errors are rule-based.Examples of knowledge-based mistakes: devising an alternate route when there is a road-block, devising a differential-diagnosis and arriving at a working diagnosis.In order to prevent, trap, and mitigate errors, we need a common language to discuss errors and how to manage them.Violations are intentional deviations from norms and rules.Corner-cutting or routine violations committed to avoid unnecessary effort or to circumvent inappropriate procedures (the written vs unwritten rules);Thrill-seeking or optimizing violations (e.g. speeding);Necessary violations that occur because the people making the rules are not the ones performing the actual work; andExceptional violations: one-off events that occur under exceptional circumstances.The Swiss Cheese Model of defences in depthDefences protect against hazards reaching losses, like barriers.These barriers have holes in them, like swiss cheeseThe holes are latent conditions and active failuresLatent conditions exist for years and are due to system factors (understaffing, policies etc)Active failures are errors created by people at the front-end (doctors, nurses, pilots, technicians etc) that are closely connected in time to bad outcomes.The current medical model is not error tolerant. It expects practitioners to be perfect. If a pharmacist, nurse, physician etc makes a mistake, the safety margins are so razor-thin that it can easily result in a bad outcome for a patient.Conversely, the response in most medical safety protocols is to warn practitioners of the dangerous conditions and then blame them when the bad outcome occurs, because this time they knew about the dangers. We should instead insist on changing the working environment, which produces the errors.Medicine being one of the oldest professions in the world and certainly one of the most complex, contributes to the difficulty in changing its culture.In changing the culture of medicine to improve the overall system, we also need to consider how the training of healthcare professionals entrenches the stigma of reporting errors.There is no true tension between training excellent physicians and reporting systemic deficiencies, because “stress testing” of physicians can happen in simulations and true-emergencies, while we also work to improve day to day conditions for everyone.We are moving towards a model of care where we speak of Centres of Excellence, rather than “who is the orthopaedic surgeon?” Medicine is team-based and even, or perhaps especially, community hospitals whose teams are well-known to each other can deliver excellent and safe care.R v Omstead, [1999] OJ No. 5701999 in Leamington, Ontario Nurse Omstead was charged with manslaughter (criminal negligence causing death) after she gave potassium chloride thinking it was furosemide because they were lookalike drugs stored close together.The judge acquitted Omstead because the Crown failed to prove beyond a reasonable doubt that her actions were a marked departure from a reasonable nurse in her situation. The judge noted that latent conditions such as the drugs looking alike and being placed together were significant factors in the error.The judge also noted that the error had been reported by Omstead herself and a conviction could have a chilling effect on future reporting of errors.Criminal trials are held to determine criminal blameworthiness and judges in such cases cannot make recommendations to hospitals or policymakers.Investigating errors as being produced by the working conditions and being related to systemic deficiencies does not mean that individuals cannot be held accountable for gross negligence (e.g. intoxication). It does mean that if, for example, training deficiencies are found, the training system can be corrected and everyone who was similarly situated can benefit.Safety intervention worth mentioning: leadership walkthroughs Dr. John Dornan, New Brunswick’s Health Minister, spends 24 hours in Moncton Hospital’s EDDr. Warren Thirsk challenges Alberta Premiere Danielle Smith to come on shift Other resources Martin Bromiley: A patient’s perspective (March 16, 2018 - YouTube 23 min)A Life In Error: From Little Slips to Big Disasters by James ReasonRandom recommendations Adam: Politics Without Politicians by Helen LandemoreAmir: The Black Swan by Nassim Taleb

Send us Fan Mail Show notes Elaine BromileyHealthy 37 year old woman for elective sinus surgery in the UK in 2005Can’t Intubate Can’t OxygenateExperienced anesthesiologist + another who joined when help was called for + a head and neck surgeon in the room + experienced OR nursesElaine’s oxygenation fell and the team could not get oxygen to her through intubation, face mask ventilation, or by using a laryngeal mask airway (LMA or rescue airway device)Several minutes went by, meanwhile a nurse brought in a cricothyroidotomy kit for surgical Front of Neck Access (FONA). The nurse announced the kit’s presence to the operating theatre but received no response.After 40 minutes (20 without sufficient oxygenation), an airway was established with an LMA.A nurse had arranged for an ICU bed and returned to the OR to tell the team, but received a look from the physicians as if to say, “What’s wrong? You’re overreacting.”Elaine was taken to the recovery room and the surgical team continued on with the rest of the patients on the list.The nurses in the recovery room were concerned that Elaine may have been having seizures and called the anesthetist, but he was busy with a patient in the OR and could not attend.Eventually, Elaine was transferred with an LMA (as opposed to a secured airway) to another hospital for ICU care.Having confirmed an unrecoverable anoxic brain injury due to the lack of oxygen on induction of anesthesia, Elaine was removed from life-sustaining therapy and allowed to die naturally.Martin BromileyElaine’s husband, and father to their two young children, was also a UK airline pilotHe told the hospital that he would “wait for the report” which is what would have happened if Elaine had died on or near an airplane in the UK. The accident investigation board, an independent investigatory body, would have determined the causes and contributing factors and then published an anonymized report with recommendations on how to improve safety.Mr. Bromiley was told that no such process existed in the UK and that “that would only happen if you sued us.”Martin commissioned just such a report, anonymized it and published it “so others can learn”.Importantly, Martin did not seek punishment. He specifically stated that the physicians and nurses that were in that room were intelligent, hard working, caring professionals. He did not blame them. He blamed the system, but the inquiry did not end there. The system can be changed but first we need to know what happened and why.The report (see MSP Ep 1 - Elaine Bromiley)Professional, third-party investigation may helpAvoid the fundamental attribution error in medicine, which suggests that when we see another’s actions, particularly errors, we attribute them to individual failings, but when we see our own, we see them as products of the environment or context.By running similar can’t intubate, can’t oxygenate scenarios, it was seen that many anesthetists at the time, fell into the same patterns of behaviour that led to Elaine Bromiley’s death, so arguments that “I wouldn’t have done that” are not credible when put to the test.Provide a “win-win-win”Patients and loved ones win as they generally want to know what happened and how the system can learn to prevent it in the future;Hospitals and healthcare systems win because safety is tangibly improved; andPractitioners win by also becoming better, but also knowing that it wasn’t all on them. That the system failed and it was not a moral or individual failure on their part. This reduces moral injury and distress for the practitioner. In this way, we preserve a much needed resource in the healthcare professional, but also in the person who is less likely to self-harm.Provide commentary about how the system as a whole, which includes the regulator, operates, as opposed to looking at one hospital or one profession.Blame-culture in medicineThe blame-culture in medicine is so ingrained that some view physicians as more culpable than pilots given a similar set of circumstances (physicians taking care of Elaine Bromiley vs pilots in United Flight 173).The idea that the physician has all the answers and can save the day all on their own is an outdated concept that has no place in modern team-based medicine.Human factors are so called because they are a part of the human condition and they exist amongst all high-risk industries.There are many ways of getting human factors training and investigation into medicine, but perhaps the most likely to be permanent is when the front-line professionals demand it.In medicine, we need senior clinicians to describe times when they’ve made mistakes. Not things that were mostly someone else’s fault, but time when they made a serious error. This will allow more junior members to talk about these issues and that is the starting point for fixing these issues. Those clinicians that do this, will be remembered as it is rare these days.Audio-Video Recordings (“Black Boxes”) in HealthcareWith much of society being recorded, patients are often surprised that we don’t audio and video record in resuscitation areas (ORs, ICUs, ED’s). One reason for this is the lack of specific legislation that exists for other industries (such as protects the black box recordings from being used in court). It is possible that current quality of care legislation can be invoked to protect such records should anyone want to start a pilot project, but certainly this is an area that needs to be explored before full implementation of nation-wide recorders would be likely. In the UK, the HSSIB has specific legislation protecting such recordings.Making it easier to get it right and harder to get it wrongIn general, we need more interventions in healthcare that make it easier to get things right and harder to get things wrong. As Professor James Reason’s work shows, errors are a part of the human condition and while we cannot change the human condition, we can change our work environment.The Health Services Safety Investigations BodyThe HSSIB works a bit differently from the AAIB (the UK’s air accident investigatory body). While aviation investigations and reports focus on specific accidents, the HSSIB may start by looking at one incident, but generally looks at a number of similar incidents and publishes a report where all the incidents have a specific theme.Independence of investigatory bodies from the regulator is of prime importance otherwise credibility is in question.Learning from excellence Medicine can export good ideas to other industries, such as “learning from excellence”. This means that we should be investigating notable times when things went right, so that we can improve our chances of success.Justifying the costs of safety endeavoursIt is impossible to measure harm that is prevented (because it is a non-event);Society spends millions of dollars investigating aviation accidents where only a few people died. Why should it matter that someone died on an airplane vs in a hospital, if there is the potential to prevent their death?We spend billions of dollars helping heal people after the healthcare system has harmed them and there can be considerable cost savings associated with improved systems safety. Safety intervention worth mentioning The YouTube videos Martin Bromiley produced to improve patient safetyJust a Routine Operation (YouTube - 6 min)Just a Routine Operation (YouTube - 14 min)Martin Bromiley: A patient’s perspective (March 16, 2018 - YouTube 23 min)Other resources A Life In Error: From Little Slips to Big Disasters by James ReasonRoyal College of Anesthetists (RoCA) NovPod - S2E11: Prevention and management of pain during caesarean section (with Susanna Stratford)Random recommendations Martin: Confessions of a Hornet Pilot by Tug WilsonAdam: Project Hail Mary audiobook, movie or Artemis II loreAmir: The Drama moviePlease consider donating at medicalsafetypodcast.com or becoming a patron of the show at Patreon.com/medicalsafetypodcast where you find full episodes

It is very hard to measure competence; there is anecdotal support from bystanders, simulation facilitators, allied health that it makes people better, but there are no RCTs to demonstrate this as it is inherently a difficult thing to measureFor physicians who are at risk of leaving high acuity fields (IE: rural physicians working emergency medicine or hospitalist medicine), increasing their confidence may help with retention, which is pivotal in some of these communities. This may also encourage junior physicians to practice at full scope, especially in underserved communities where it is traditionally hard to hire physiciansSimulation directly works on team dynamics; improving team dynamics may improve the work environment and improve retentionDifferent kinds of simulationThere is a specific kind of simulation focused on logistics and ergonomicsAlthough some Simulation focused on CRM principles may bring this out, there is a dedicated form of simulation meant to test thisThis can be implemented locally without a lot of equipment or cost by a hospital “code committee” to solely look at implementation in a site or systemRapid cycle deliberate practice is a tool you can use to work on specific technical skills in a short time frame without needing a full theatre simulation experienceCan we use simulation as an evaluation tool for competency?In medicine, we are rarely given the opportunities to practice what we learn in simulation, or real life scenarios reflective of what we see in simulation, so there are not many opportunities to practice these events prior to being evaluated on themIf we build a training system that the skillsets of CRM are taught well, and people have the opportunity to practice those skills, in training and in independent practice, with a very low barrier to entry, we may have the foundations for using simulation as a competency assessment tool, like they have in aviationThere are some residency programs that make simulation a mandatory part of their program and use it as a formal assessment tool during their licensing Some key CRM themesFixation vs focus:Fixation is when you devote your attention and mental resources to the wrong thing in a crisis situationFocus when you devote your attention and mental resources to the correct thing in a crisisIf you are maintaining your situational awareness (an accurate mental model of what is occurring and what the priorities are) then you are not fixated.The issue is that our attention narrows when performing complex tasks and we lose our situational awareness (e.g. when intubating, we momentarily lose sight of the bigger picture).Either delegate such tasks (IV access, intubation, chest tube insertion, etc) or have someone else run the rest of the resuscitation and then inform you of what occurred while you were performing that task.If our system is built around the infallibility of a single person, or a few key people, our system will inevitably fail because no one can be perfect 100% of the timeCrisis resource management is fundamentally moving from a theoretical solution to a problem in crisis, to a practical solution to this problemWays to improve your performance in crisisThink about the resources you have available that can help you; sometimes this is a colleague, or a more experienced member of the team.

Send us Fan Mail What is Crisis Resource Management (CRM)?It is a set of skills that helps improve team performance through communication, leadership, and interpersonal skills.It can help build a common language and shortcuts so that even people that have not worked together before can work well together. Used well, it can improve efficiency.While it is more formalized in other industries (aviation, military), it exists in medicine and has existed for some time, but is more practitioner-dependent.Order of priorities when leading a resuscitationEstablish communication, your role, and the role of others (“I’m Dr. [X], I will be leading this resuscitation. Who else do I have in the room with me?”)Try to build some rapport, if time permitsGather information, starting with threats to lifePrioritize treatment, diagnosis, and transportationMaintain situational awareness by continually seeking new information and revaluate the diagnoses, need for more information and revaluate the decisions that have been made and need to be madePrioritize the patient’s safety but also remember your colleagues’ including transportation teamHow to manage your stress response to perform optimallyTake a breath“Slow is smooth, smooth is fast”Use a systematic approachMaintain control of the room (ask for quiet when necessary, ask those not immediately involved in the resus to step out, )Summarize the situation and seek the input of othersThe foot of the bed is often a good place for the resuscitation leader. They can see the monitor and all of the work being done, as well as the patient and their colleagues. It also helps reduce the urge to physically do tasks that might in the leader’s skillset, but that would take them away from leading the team.Practicing CRMVisualize  / walkthrough / tabletop common life threatening scenarios (head injury, multisystem trauma, obstetrical hemorrhage, etc).

Who knows what’s going with X, Y, and Z?”Summarizing for the team (shared mental model)Where we’ve beenWhere we are currentlyWhere we need to bePriorities for making that happenTelling the team the working diagnosis (e.g. respiratory failure, PE, etc) can help them access their own mental schema for that and they can watch for your blind spots and anticipate things that may be otherwise forgotten.

Send us Fan Mail Aspects of CRMMaking a welcoming environment, so that others feel they can speak upCRM is not about being perfect. It’s about identifying and mitigating the times of increased risk of making mistakes and identifying why a particular mistake was made.The perceived tension between performance and “soft skills” (CRM)Some people view these non-technical skills as costing time and money and not contributing to patient safety or as detracting from efficiency. The reality is that good CRM skills make teams more efficient. Additionally, we are no longer in a stage in medicine where we can say that leadership or non-technical skills don’t matter. We have plenty of evidence that failures of leadership have directly resulted in bad outcomes (morbidity and mortality).Additionally, CRM skills improve the working environment for all, which leads to the preservation of healthcare workers and mitigates burnout.The origins of CRMCRM developed in aviation because of a data-driven approach where successive accident investigations determined that the majority of aviation accidents were caused by human error (team performance) rather than mechanical failure, as had happened in the past.In medicine, we can safely assume the same trend, but as a profession that purports to follow the evidence, we should investigate and build a dataset on which to make these kinds of decisions. This could look like the aviation-style medicine incident investigation systems that exist in the UK and Norway and could use systems like audio and video recording of operating rooms, ICUs, and resuscitation bays. It would also likely require a change to legislation to protect that data from being used in litigation, as currently exists for aviation black boxes.The evolution of CRM in aviationfrom elective courses to mandatory SOPs to the point where even if a pilot completed the tasks technically correct, but exhibited poor CRM skills, they would fail their flight test.“Anticipation builds vigilance; vigilance aids recognition; recognition leads to recovery.”CRM & Error ManagementIn aviation, CRM treats errors as inevitable events to be managed, not moral failures.Error prevention: reduces the chance of making an error in the first place. Usually through human factors engineering and improving working conditions. The focus is here, which involves planning, discipline, and preparation. (e.g. aircraft design, fatigue risk management, rules around how much additional fuel must be onboard, use of checklists to avoid memory errors).Error trapping: catching the error before there is any effect. This is often about vigilance and teamwork. (e.g. crosschecking, callouts, assertiveness to encourage speaking up)Error mitigation: to limit the severity of outcomes. This is about resilience and recovery. (e.g. unstable approach leads to missed approach. Short on fuel > divert to alternate.)Error chains: a single error rarely, if ever, causes a major accident. It is untrapped, unmitigated error chains that result in accidents.In clinical medicine we see this often: errors are inevitable (ask any clinician), harm is not.Medical examples of error management:Error prevention: pre-printed order sets, standardize drug trays, avoiding look-alike drugs.Error trapping: Surgical “time-out” checklists before skin incision, closed-loop communication during resuscitation.Error mitigation: iatrogenic opioid overdose that was recognized and naloxone is given.Acceptable delays to ensure appropriate margins of safetyThere are occasions in medicine and aviation where one group of professionals needs to push back on the production pressure to perform tasks appropriately in order to ensure safety. Both professions must understand that certain delays are required, however, the degree to which this happens is not consistent around the world. Mike gave the example of arriving early to train a new pilot and occasionally needing to close the cockpit door after saying the flight crew needed ten minutes. Amir and Adam gave anesthesia examples where they had to delay the OR in order to prevent or trap errors (additional airway equipment, provide preoperative medications). CRM is alive and well in medicine, but we must meeting people where they are atIn this episode, there were many examples where medical teams are performing good CRM, particularly Threat and Error Management through the use of briefings. Mike mentioned the public health example of meeting people where they are. We should acknowledge that a lot of CRM strategies and skills exist in modern medicine, but much of it is not formalized.CRM as an inclusive tool to improve team performanceCRM by its nature of improving team performance has its foundation on clear communication from all team members. While it used to be called Cockpit Resource Management, it changed to become Crew Resource Management to emphasize the inclusion of flight attendants, ground personnel, air traffic controllers, etc. Many errors have been prevented or trapped by ancillary personnel speaking up.Escalation of Language of ConcernIn order to encourage everyone to speak up, formalized escalation of language models exist. In aviation this is the PACE model:Probing: “I’ve never seen [x] done before. Can you tell me why you’re doing it this way?”Alert: “The oxygen saturation is 90%.”Challenge: “The oxygen saturation is critically low, we need to move to BiPAP.”Emergency: “This is an emergency. Dr. [x] will perform a cricothyroidotomy.”In an emergency, you can start ‘higher up’ on the PACE ladder, as appropriate, but starting lower is less aggressive and can prevent conflict.Instrumentation to avoid fixation-induced loss of situational awareness Cockpit instrumentation is being redesign to account for the fact that hearing is one of the first things to go in a high cognitive load. Rather than just the aural announcements of “terrain, terrain”, the words are being displayed in red letter on the displays in front of the pilots.Cognitive load in training: much of what we can process related to cognitive load. As novice become experts, they can deal with greater and greater cognitive loads before becoming task saturated. This is well-recognized in pilot training.Line Oriented Safety Audits (LOSA) Trained observers in the cockpit observe and report on real-world operations. In this way, an accurate analysis of company-specific operations can occur. These observe comment on both salutary solutions and errors which can then be fed-back to trainers and risk management.Theoretically, there is no reason such a system could not exist in medicine. In such a system, trained people would observe physicians and provide information solely for the purpose of improving safety, rather than any punitive action.Use people’s first names as opposed to their title, when it is critical to get their attention.Who can do what tomorrow Policy / government / regulator: Canada could have an aviation-style investigation board for medical incidents, as the UK and Norway currently have. This would be a non-punitive investigation conducted by a knowledgeable independent board to determine the causes and contributing factors of specific medical incidents. The report would be anonymized and publicly available and would include recommendations for practitioners, training institutions, medical device manufacturers, and regulators.Hospitals / heads of department: We saw in aviation how CRM was a data-driven response in the 1970’s and onward to team performance becoming the predominant reason for aviation accidents. We don’t have the same quality of evidence in medicine, however, we need not wait for the government or regulator to mandate the technology that would lead to this data becoming available. The technology exists for audio and video recording (“black boxes”) of the OR, ICU, and resuscitation bays of emergency departments. Individual hospitals or departments could run a pilot program (ensuring that such information is prevented from being used in litigation by invoking current quality of care investigation legislation). Much like Tommy Douglas’s creation of publicly-funded healthcare in Saskatchewan, which was later expended to cover all of Canada, any hospital that begins such an endeavour may be credited with pushing the entire profession in this direction.Residency program directors: while modules on human factors are a good start, we can look to the evolution of CRM in aviation and see that formalized CRM training with high-fidelity simulation is the gold standard. For those that are already doing this, Mike’s comments about the field of aviation ideally incorporating CRM into earlier stages of pilot training can be instructive for the medical field.Other Resources: United Flight 232 - Captain Al Haynes (YouTube) Next episode: Escalating Language of Concern with Dr. Katie Lin

Send us Fan Mail In this episode Amir and Adam discuss three aviation accidents that parallel the Elaine Bromiley case. Human factors in medicine: As Captain Bromiley put it, this was not an individual failure. It was a system failure. It was a failure of human performance. In aviation, 75% of airline accidents are due to human factors rather than mechanical failure. Eastern Airlines Flight 401 (1972)Fixation-induced loss of situational awareness.Troubleshooting a landing gear light indicator problem in the cockpit (one of the landing gear lights would not indicate the gear was down and locked).The autopilot was engaged and the aircraft was flying over unlit terrain (the Florida everglades) at night.One of the flight crew inadvertently bumped the control column which disengaged the autopilot.Despite an altitude alert chime being audible on the Cockpit Voice Recorder (CVR), none of the crew responded to it.The aircraft slowly descended and impacted terrain.The landing gear was in fact down and locked and the failure of a single light bulb resulted in many fatalities.United Airlines Flight 173 (1978)Fixation-induced loss of situational awareness leading to fuel exhaustion and crashing in PortlandTroubleshooting a landing gear light indication problem, similar to Eastern Airlines Flight 401Again the light failed to indicate, but the gear was later found to be in a safe positionThis time the Captain continued to circle to try to troubleshoot the problem and optimize the conditions for the emergency landing with a potentially unsafe landing gear.Despite the First Officer (FO) and Flight Engineer (FE) attempting to tell the Captain that the aircraft was dangerously low on fuel, the Captain continued to take time to work the landing gear problem.When the engines began to fail, the Captain was surprised that it was because of a lack of fuel.Air Florida Flight 90 (1982)Poor crew coordination and lack of assertiveness / failure of leadership leading to a crash on departure in icing conditions.The failure to engage the engine anti ice later led to a false indication in the cockpit instruments showing that the engines were developing sufficient thrust for takeoff when they weren’t.The Captain ignored the First Officer’s repeated concerns about the amount of ice on the wings and whether the engines were developing sufficient power on takeoff.Just a Routine Operation (YouTube - 6 min)Just a Routine Operation (YouTube - 14 min)Martin Bromiley: A patient’s perspective (March 16, 2018 - YouTube - 23 min)Eastern Airline Flight 401  Mayday Fatal Distraction - S05E09 (YouTube)United Airlines Flight 173 - Mayday Focused on Failure  S12E08 (YouTube)Air Florida Flight 90 - Mayday Disaster on the Potomac - S13E04 (YouTube)ACCRAC Ep 325: The WISH Inventory and Well-Being in Anesthesiology with Drs.

Send us Fan Mail Welcome to the Medical Safety Podcast where we aim to improve the safety of our healthcare system through the integration of human factors into medical incident investigation and proactive safety measures. This podcast is hosted by two Canadian anesthetists, Drs. Adam Shehata and Amir Hamid. In the inaugural episode, we take a look at the 2005 death of Elaine Bromiley and the lessons learned from it. Elaine Bromiley Healthy 37 year old woman for elective sinus surgery in the UK in 2005Can’t Intubate Can’t OxygenateExperienced surgical teamElaine’s oxygenation fell and the team could not get oxygen to her through intubation, face mask ventilation, or by using a laryngeal mask airway (LMA)Several minutes went by, meanwhile a nurse brought in a cricothyroidotomy kit for surgical Front of Neck Access (FONA). The nurse announced the kit’s presence to the operating theatre but received no response.After 40 minutes (20 without sufficient oxygenation), an airway was established with an LMA.A nurse had arranged for an ICU bed and returned to the OR to tell the team, but received a look from the physicians as if to say, “What’s wrong? You’re overreacting.”Elaine was taken to the recovery room and the surgical team continued on with the rest of the patients on the list.The nurses in the recovery room were concerned that Elaine may have been having seizures and called the anesthetist, but he was busy with a patient in the OR and could not attend.Eventually, Elaine was transferred with an LMA (as opposed to a secured airway) to another hospital for ICU care.Having confirmed an unrecoverable anoxic brain injury due to the lack of oxygen on induction of anesthesia, Elaine was removed from life-sustaining therapy and allowed to die naturally.Martin BromileyElaine’s husband, and father to their two young children, was also a UK airline pilotHe told the hospital that he would “wait for the report” which is what would have happened if Elaine had died on or near an airplane in the UK. The accident investigation board, an independent investigatory body, would have determined the causes and contributing factors and then published an anonymized report with recommendations on how to improve safety.Mr. Bromiley was told that no such process existed in the UKMartin commissioned just such a report “so others can learn”.Importantly, Martin did not seek punishment. He specifically stated that the physicians and nurses that were in that room were intelligent, hard working, caring professionals. He did not blame them. He blamed the system. The system can be changed but first we need to know what happened and why.The reportA failure of leadership and communication which led to a fixation-induced loss of situational awarenessThe physicians became fixated on intubating to the exclusion of other possibilities of providing oxygen (such as FONA).They became so fixated that they did not respond to the nurses who later reported knowing what needed to happen but being unable to communicate it effectively.YouTube videos Martin Bromiley produced to improve patient safety:Just a Routine Operation (6 min)Just a Routine Operation (14 min)Martin Bromiley: A patient’s perspective (March 16, 2018 - 23 min)Please consider donating at medicalsafetypodcast.com
