Health system facilitators and barriers to the integration of mental health services into primary care in the Democratic Republic of the Congo: a multimethod study.

Background: The integration of mental health into primary care-i.e., the process by which a range of essential mental health care and services are made available in existing multipurpose health care settings that did not previously provide them-can be facilitated or hindered by several health system factors that are still poorly understood. This study aimed to identify health system facilitators and barriers to the integration of mental health services into primary care in the Democratic Republic of the Congo (DRC) to improve the success rate of integration programs.

Methods: We conducted a multimethod, cross-sectional exploratory study. Stakeholders (managers, health service providers, service users, etc.) from sixteen of the twenty-six provinces of the DRC participated. We collected qualitative data through 31 individual, semistructured, face-to-face key informant interviews. We then collected quantitative data through a population-based survey of 413 respondents. We analyzed the interviews via thematic analysis, assigning verbatims to predefined themes and subthemes. For the survey responses, we performed descriptive analysis followed by binomial logistic regression to explore the associations between the variables of interest.

Results: Strong leadership commitment, positive attitudes toward mental health care, the availability of care protocols, mental health task sharing (p < 0.001), and sufficient numbers of primary care providers (PCPs) (p < 0.001) were identified as key health system facilitators of successful integration. However, barriers to integration are mainly related to a poor understanding of what integration is and what it is not, as well as to the poor functionality and performance of health facilities. In addition, stigma, low prioritization of mental health, lack of mental health referents, low retention rate of trained health professionals, lack of reporting tools, lack of standardized national guidelines for integration (p < 0.001), lack of funding (p < 0.001), shortage of mental health specialists to coach PCPs (p < 0.001), and lack of psychotropic medications (p < 0.001) were identified as health system barriers to integration.

Conclusion: Improving the functionality of primary care settings before integrating mental health care would be beneficial for greater success. In addition, addressing identified barriers, such as lack of funding and mental health-related stigma, requires multistakeholder action across all building blocks of the health system.
