RESUMO
BACKGROUND: Cardiovascular disease among patients with severe mental illness in England is a major preventable contributor to premature mortality. To address this, a nurse and peer-coach delivered service (Primrose-A) was implemented in three London general practices from 2019 (implementation continued during COVID-19). This study aimed to conduct interviews with patient and staff to determine the acceptability of, and experiences with, Primrose-A. METHODS: Semi-structured audio-recorded interviews with eight patients who had received Primrose-A, and 3 nurses, 1 GP, and 1 peer-coach who had delivered Primrose-A in three London-based GP surgeries were conducted. Reflexive thematic analysis was used to identify themes from the transcribed interviews. FINDINGS: Overall, Primrose-A was viewed positively by patients and staff, with participants describing success in improving patients' mental health, isolation, motivation, and physical health. Therapeutic relationships between staff and patients, and long regular appointments were important facilitators of patient engagement and acceptance of the intervention. Several barriers to the implementation of Primrose-A were identified, including training, administrative and communication issues, burden of time and resources, and COVID-19. CONCLUSIONS: Intervention acceptability could be enhanced by providing longer-term continuity of care paired with more peer-coaching sessions to build positive relationships and facilitate sustained health behaviour change. Future implementation of Primrose-A or similar interventions should consider: (1) training sufficiency (covering physical and mental health, including addiction), (2) adequate staffing to deliver the intervention, (3) facilitation of clear communication pathways between staff, and (4) supporting administrative processes.
