Social determinants of health (SDOH) are social factors that have a causal role in ill health and have an adverse effect on health outcomes. SDOH are part of the UK medical student curriculum but mainly discusses epidemiologically. There are few educational approaches that aim to incorporate an understanding of SDOH into the experiential and competency-based elements of undergraduate medical education. Prisoners are a population who experience high levels of stigma, social adversity and health disadvantage. Clinical attachments in prison may teach students about the impact of SDOH in a vivid and memorable way. Aims: We aim to explore changes in medical students' knowledge/attitude towards SDOH during and after psychiatry placements at HMP-Berwyn prison.

All year four medical students on psychiatry placement in North East Wales during 2021–2022 participated. In each of the six placement cohorts, one student did their psychiatry placement in prison. All the other students visited for one day. All students participated in two seminars focused on their prison experience and SDOH in psychiatry. Baseline and mid-placement bespoke questionnaires were completed, and all students participated in end-of-placement individual interviews.

29 students participated. Student assessment of the importance of SDOH did not show a significant change between baseline and mid-placement. However, student attitudes to experience in prison became more positive at end-of-placement. Comparing baseline to mid-placement questionnaires showed a 14% increase in students' rating of prison placements as educationally beneficial. 14% of students mentioned improved confidence in dealing with challenging patients, and 28% commented on the benefits of exposure to incarcerated patients. Interestingly, only 3% of students considered hospital placement more beneficial than prison placement. Prison placement was considered an exceptional experience than other settings by 17%.

There are no previous UK empirical studies on medical student placements in prison. Overseas studies identify reduced anxiety over dealing with demanding patients. Our findings so far lack statistical power but show positive satisfaction and knowledge trends amongst participants. Prison placement appears to be acceptable and educationally valuable. It offers opportunities for experiential teaching about SDOH. In addition, it may improve student understanding of a marginalised and stigmatised population.

On completion, this study may provide evidence on one method of improving attitudes toward marginalised people and understanding SDOH in the medical profession.
