Abstract The Community Mental Health Education and Detection (CMED) tool was designed and validated for community health workers (CHWs) in South Africa to promote mental health education, detection and linkage to care for adults at risk of mental health conditions. This study evaluated CMED scale-up using implementation research to understand reach and adoption.Routinely collected CHW data from three scale-up community areas were analysed over six months. Using the Reach and Adoption components of the RE-AIM framework, data included the (i) number of CMED administrations; (ii) proportion of identified presumptive cases; and (iii) proportion of referred cases who received care. These data identified high-and low-adopting CHW teams. Observations and repeated group discussions explored factors influencing adoption. CHWs completed 2,135 CMED administrations. Seventeen percent screened positive and were referred for further assessment at PHC facilities; 62% of those referred presented for assessment, diagnosis, and management. Adoption varied across teams. Barriers included poor data systems and inconsistent supply of mental health services. Supportive leadership and supervision were strong facilitators of adoption. Policy uptake signalled maintenance. Findings suggest the CHW-delivered CMED tool is viable and useful for narrowing the treatment gap by strengthening demand for and access to mental health services.

Study methods

An observational research design using a pragmatic application of the RE-AIM implementation outcome framework (Glasgow et al., 2013), previously used in the main study (Petersen et al., 2023), was adopted to assess Reach and Adoption. Assessment of Effectiveness was not possible under real-world conditions. In terms of Implementation, a mentoring and support tool was developed to build confidence and support the delivery of all CMED components. This tool was used qualitatively during mentoring visits rather than as a quantitative measure, limiting the ability to formally assess implementation fidelity. Assessment of Maintenance was inhibited by funding and time constraints requiring a lengthy follow-up period to assess continued use of the tool, although we do report on adoption of the tool into policy. Routinely collected data were used to examine Reach and Adoption components as they pertain to household-level identification, referral and access to mental health and psychosocial services as part of routine care.

Limitations

The analysis was limited by our reliance on real-world data, which varied in completeness and consistency across clinics, with logistical and financial constraints preventing the collection of parallel research data to verify routine CHW self-reported data. Complete care cascade data were available for only three of the nine original community catchment areas and their associated WBPHCOTs. This may have introduced selection bias, as facilities with more complete routine data systems and stronger implementation processes may also have been more likely to demonstrate higher levels of intervention uptake. Despite this limitation, 14,262 household visits were conducted across the three community catchment areas, of which 2,135 received the CMED intervention during the 6-month study period, indicating that the findings were drawn from implementation at substantial scale. In addition, the variation observed across the three WBPHCOTs in leadership, referral coordination and intervention adoption suggests that the included sites reflected differing implementation contexts rather than only high-performing settings. Nevertheless, the findings should be interpreted cautiously, and further research across a broader range of implementation contexts is required to better understand the generalisability of these findings across WBPHCOTs and PHC settings in South Africa.

A 90-day district inquiry

Days 1–15 · Appraise. Read the source methods, recruitment, comparator, outcomes and limitations. Record how the study setting differs from your district and which claim the design can support.
Days 16–30 · Design. Choose one school improvement question with teachers. Protect a short shared planning cycle, agree an instructional change and use a common rubric for examining student work. Agree participation, privacy protections, baseline and stopping rules before starting.
Days 31–60 · Observe. Collect the pre-agreed measures, keep a log of implementation changes and invite confidential voluntary feedback. Preserve existing support for staff and learners.
Days 61–90 · Decide. Review implementation fidelity, teacher time and independently scored student work against a recorded baseline. Examine access differences and competing explanations before attributing changes to leadership. Make a dated decision to stop, revise or extend the inquiry.
