An introduction to OHA!, a tool currently being developed which aims to assist dentists in accessing the most reliable evidence regarding the effectiveness of common dental treatments. The OHA! repository has been purposefully crafted to be exceptionally selective and compact, ensuring that users can easily find straightforward and valuable answers to their dental clinical questions. During the presentation, Professor Paulo Nadanovsky will show two sample dental fact boxes (in draft form) that have been developed. One pertains to the success rate of root canal treatment, while the other focuses on the impact of shorter versus longer intervals between dental check-ups on oral health. Patients expect doctors to take action to help them, and the more treatment or diagnostic tests, the better they feel. Doctors genuinely want to help and can often come up with various treatment or testing options to try. Consequently, this leads to a situation where everyone becomes perpetual patients, regardless of their actual health needs and potential benefits – essentially, an overuse of healthcare. Furthermore, there is a pervasive illusion of certainty among healthcare professionals, including physicians and dentists. This illusion entails the belief that treatments are always effective, diagnostic tests are infallible, and there exists only a single, optimal treatment or management approach. Consequently, there is often a lack of systematic comparisons between the pros and cons of different options. To dispel this illusion of certainty, reduce excessive healthcare practices, and promote clear thinking when considering interventions, the provision of clear information is essential. The practice of evidence-based healthcare involves two distinct roles: that of evidence consumers and evidence producers. Consumers, including clinicians and the general public, often lack the expertise needed to evaluate and choose the most reliable evidence. Hence, it falls upon those producing healthcare evidence to assume the role of experts and develop tools that simplify the integration of the best available evidence into the decision-making process for clinicians and patients alike. Bio: Professor Nadanovsky graduated as a dentist in Rio de Janeiro, Brazil. He worked for a few years in the clinic (mainly periodontics), then migrated to public health and epidemiology and obtained a PhD from the University of London in 1993. He witnessed the birth of the evidence-based medicine movement and of the Cochrane Collaboration while working as a lecturer at the London Hospital Medical College and at University College London (afterwards it was renamed Queen Mary and Westfield College). Professor Nadanovsky taught evidence-based dentistry between 1993 and 1997 and since 1997 has been teaching epidemiology and evidence-based health care to physicians, dentists, nutritionists, and other health care professionals. He supervises PhD and MSc students, and his main interest is in overdiagnosis and overtreatment in health care in general, and more specifically, in dentistry.

Using a variety of examples of fast and slow qualitative research this talk explores the affordances of rapid methods, and help researchers decide if and where to use them in their own work. Methodologies of rapid qualitative research have been around for decades, gaining particular prominence during the Covid-19 pandemic. They spark intense debate about the place of rapid qualitative methods in healthcare research. What questions are they best suited to answer? Is speed a trade-off for quality? Which parts of the qualitative process can and can't be done at pace? If can do research quicker, should we? Dr Anna Dowrick (https://www.phc.ox.ac.uk/team/anna-dowrick) is an interdisciplinary social scientist, spanning medical sociology, medical anthropology and science and technology studies. Her research explores how social injustice can be seen and acted upon through understanding experiences of health and illness, with a view to informing and improving the design of public services. She has used rapid and slow qualitative designs to explore issues including: improving access to support for domestic violence and abuse, food poverty interventions, cancer detection, Covid and Long Covid, and beauty 'injectables'.

Dr Alexandra Burton reports on the SHAPER-PND study exploring singing's effect on postnatal depression in new mothers Singing has shown positive effects on maternal mood and mother–child bonding. The Scaling-Up Health-Arts Programmes: Implementation and Effectiveness Research-Postnatal Depression (SHAPER-PND) study will analyse the clinical and implementation effectiveness of a 10-week programme of singing sessions for PND in new mothers. This talk will present findings from the evaluation of an adapted online programme during the COVID-19 pandemic and describe the methods used to evaluate the main in-person programme. This free guest lecture is part of the Mixed Methods in Health Research module, part of the Oxford University Evidence-Based Health Care (EBHC) programme (https://www.conted.ox.ac.uk/courses/mixed-methods-in-health-research?code=O22C212B9Y).

Dr Clare J Taylor, Academic GP, explores how we can use large, anonymised GP datasets to improve our understanding of heart failure management in primary care. Nearly all UK residents are registered with a general practice and data collected during routine consultations can be used by researchers to understand more about common diseases. Heart failure occurs when the heart has been damaged and is struggling to pump enough blood to meet the needs of the body. Patients can feel breathless, exhausted and have swollen legs but treatments to improve quality of life and outlook are available. In this lecture, Dr Taylor explores how we can use large, anonymised GP datasets to improve our understanding of heart failure management in primary care. With a focus on the patient throughout, she presents her recent work on heart failure diagnosis and survival to illustrate the power, and limitations, of using big GP data for research and to ultimately improve patient care. Part of the Evidence-Based Health Care programme. About the speaker: Dr Clare J Taylor is a Clinical Lecturer in the Nuffield Department of Primary Care Health Sciences. Her research explores heart failure in primary care using big data epidemiology, prospective studies, and qualitative work. The findings have been published in high-impact journals and informed national and European heart failure policy. Clare is also experienced in postgraduate teaching and doctoral supervision and was a member of the National Institute for Health and Care Excellence Chronic Heart Failure guideline committee. She also works as an NHS general practitioner. Creative Commons Attribution-Non-Commercial-Share Alike 2.0 UK: England & Wales; http://creativecommons.org/licenses/by-nc-sa/2.0/uk/

In 2022 a Canadian population based retrospective cohort study hit the headlines in the U.K. by claiming that women were 32% more likely to die if operated on by a male surgeon. The study was led by Christopher Wallace who sought to examine the link between surgeon patient sex discordance and postoperative outcomes. Data was collected for over 1.3 million patients and nearly 3000 surgeons were included. It found that 14.9% of patients had one or more adverse postoperative outcome. But that worse outcomes were seen for female patients operated on by male surgeons, but not for males operated on by female surgeons. Together with Director of the Centre for Evidence-Based Medicine, Professor Carl Heneghan, and EBHC DPhil Director, Dr. Jamie Hartmann-Boyce, Dr. Anne Marie Boylan discusses what this means for women, the accuracy of the study and whether it has any relevance here in the U.K. They also speak to Emily McFadden, a Senior Statistical Epidemiologist here at Oxford, Sunil Patel, a Canadian surgeon completing his DPhil in evidence based healthcare and Sharon Dixon, a GP and academic who's researching women's health in the department.Together with Director of the Centre for Evidence-Based Medicine, Professor Carl Heneghan, and EBHC DPhil Director, Jamie Hartmann-Boyce, Dr. Anne Marie Boylan discusses what this means for women, the accuracy of the study and whether it has any relevance here in the U.K. Creative Commons Attribution-Non-Commercial-Share Alike 2.0 UK: England & Wales; http://creativecommons.org/licenses/by-nc-sa/2.0/uk/
