RESUMO
Older adults are the fastest growing sub-group in prisons. They have complex health, social care and custodial needs and often the support they receive is sub-optimal. The Older prisoner Health and Social Care Assessment and Plan (OHSCAP) aimed to better meet these inter-related needs. As part of a wider study, a randomised controlled trial was conducted to evaluate the OHSCAPs effectiveness in meeting older prisoners' health, social care and custodial needs in comparison to treatment as usual. This article describes the nested qualitative study which aimed to explore the barriers and facilitators to the effective implementation of the OHSCAP. Semi-structured interviews were conducted with older adults (n = 14) and staff members t (n = 12). Data was analysed using the framework method. Three overarching key themes were identified. These were: (1) balancing care and custodial requirements; (2) prison, health and social care silos; and (3) rigid prison processes. Prison is an important opportunity to engage residents and improve public health. Cultural and strategic change is required for health, social care and custodial interventions, such as the OHSCAP, to be successfully implemented into prison settings.
