Challenges and opportunities for implementation and dissemination of a task- sharing counselling intervention for depression at primary health care level in South Africa

BACKGROUND: The treatment gap for mental health services is a growing public health concern. A lay-counselling service located at primary health care (PHC) level could potentially help to close the large treatment gap for common mental disorders in South Africa. The aim of this study was to understand multilevel factors contributing to implementation and potential dissemination of such a service for depression at PHC level. METHODS: Process qualitative data of the lay-counselling service for patients with depressive symptoms was collected alongside a pragmatic randomized controlled trial evaluating a collaborative care model that included a lay-counselling service for patients with depressive symptoms. Semi-structured key informant interviews (SSI) were conducted with a purposive sample of PHC providers (lay-counsellors, nurse practitioners, operational managers), lay-counsellor supervisors, district and provincial managers, and patients in receipt of services. A total of 86 interviews were conducted. The Consolidated Framework for Implementation Research (CFIR) was used to guide data collection as well as Framework Analysis to determine barriers and facilitators for implementation and dissemination of the lay-counselling service. RESULTS: Facilitators identified include supervision and support available for counsellors; person focused counselling approach; organizational integration of the counsellor within facilities. Barriers included lack of organizational support of the counselling service, including lack of counselling dedicated space; high counsellor turnover, resulting in a counsellor not available all the time; lack of an identified cadre to deliver the intervention in the system; and treatment of mental health conditions including counselling not included within mental health indicators. CONCLUSIONS: Several system level issues need to be addressed to promote integration and dissemination of lay-counselling services within PHC facilities in South Africa. Key system requirements are facility organizational readiness for improvement of integration of lay-counselling services; formal recognition of counselling services provided by lay counsellors as well as inclusion of lay counselling as a treatment modality within mental health treatment data element definitions and the need for diversification of the roles of psychologists to include training and supervision of lay counsellors was also emphasized.
