The concurrent epidemics of HIV, diabetes, and hypertension strain health systems in sub-Saharan Africa. Integrating non-communicable disease screening into existing HIV services is a proposed strategy to enhance efficiency, but evidence on its operational implementation in routine African settings remains limited. This meta-analysis aimed to synthesise operational research evidence on integrating diabetes and hypertension screening within HIV testing services in Zambia's Copperbelt Province, from an African health systems perspective. A systematic search was conducted across multiple electronic databases for operational research studies, including programme evaluations and observational studies. Studies were screened against pre-defined inclusion criteria. Data on screening uptake, yield, operational processes, and health system challenges were extracted. A qualitative synthesis was performed due to significant heterogeneity in outcome measures and study designs. Integrated screening was operationally feasible but revealed systemic challenges. The synthesis indicated a high prevalence of undiagnosed hypertension among clients attending HIV testing services. Key operational themes included increased staff workload, frequent commodity stock-outs, and the need for adapted counselling protocols. Integration shows potential for improving case-finding of non-communicable diseases. However, its effectiveness is constrained by persistent health system weaknesses common in resource-limited settings. Success depends on addressing these systemic bottlenecks, not merely adopting the integrated clinical model. Strengthen supply chains for essential diagnostic commodities. Develop and validate simplified, integrated counselling and clinical guidelines. Implement routine monitoring and evaluation frameworks for integrated services to inform quality improvement and policy decisions.

This synthesis provides consolidated evidence for policymakers on the real-world implementation of integrated screening, highlighting critical health system prerequisites for successful scale-up in similar African contexts.
