Intellectual disabilities teaching for medical students: a scoping review

Background: People with intellectual disabilities are a marginalized group whose health experiences and outcomes are poor. Lack of skill and knowledge in the healthcare workforce is a contributing factor. In England, there is a new legislative requirement for mandatory intellectual disability training to be given to the existing healthcare workforce, including doctors. There is a lack of evidence about effective models of educational delivery of such training in medical schools. We undertook a scoping review to assess the range of intellectual disabilities educational interventions and their effectiveness. Methods: We included any study from 1980 onwards which reported an educational intervention on intellectual disability, or intellectual disability and autism, for medical students from any year group. Databases searched included PUBMED, ERIC, Scopus and Web of Science as well as searches of grey literature and hand searching two journals (Medical Education and Journal of Learning Disabilities). 2,020 records were extracted, with 1,992 excluded from initial screening, and a further 12 excluded from full-text review, leaving 16 studies for inclusion. Data was extracted, quality assessed, and findings collated using narrative analysis. Results: We found a variety of intervention types: classroom-based teaching, simulation, placement, home visits, and panel discussions. There was substantial variation in content. Most studies involved lived experience input. Across studies, interventions had different learning outcomes which made it difficult to assess effectiveness. Overall study quality was poor, with high use of non-validated measures, making further assessment of effectiveness problematic. Conclusions: There is a need for more consistency in intervention design, and higher quality evaluation of teaching in this area. Our review has drawn attention to the variety in teaching on this topic area and further research should focus on updating this review as curriculum changes are implemented over time.
