Abstract
Background In light of the increasing burden of non-communicable diseases on health systems in low- and middle-income countries, particularly in Sub-Saharan Africa, context adapted cost effective service delivery models are now required as a matter of urgency. Multiple models have thus been trialled across Africa with varying degrees of success. Zimbabwe is a low-income country with unique socio-economic challenges but similar dual disease burden of infectious chronic diseases such as HIV and non-communicable diseases. We aim to describe the experience of setting up and organising a nurse-led Diabetes Mellitus (DM) and Hypertension (HTN) model of care in a rural context of a low-income country from July 2016 to June 2019.Methods A descriptive study based on a conceptual framework successfully applied in the roll-out of antiretroviral therapy in Manicaland Province, Zimbabwe. Attempting to mirror the HIV experience, we describe the key enablers in the design and implementation of the model: decentralization of services, integration of care, simplification of management guidelines, mentoring and task-sharing, provision of affordable medicines, quality assured laboratory support, patient empowerment, a dedicated monitoring and evaluation system, and a robust referral system.Results 11 out of 51 health facilities were selected in Chipinge district, of which nine were primary health care (PHC) clinics and two were hospitals. DM/HTN services were set up and integrated into the general out-patient department or pre-existing HIV clinics. In one hospital, an integrated chronic care clinic was established. Through structured intensive mentoring, including simplified protocols, nurses in seven PHC facilities and one hospital developed sufficient knowledge and skills to diagnose, initiate treatment and monitor DM/HTN patients. Overall, more than 3000 patients were registered in a dedicated recording system and offered education. Free medication with differentiated periodic refills and regular monitoring of blood pressure and/or blood glucose with the use of glycosylated haemoglobin were provided.Conclusion Our experience shows that it is feasible to implement nurse-led decentralized integrated DM/HTN care in a high HIV prevalence rural, low-income context. Developing a context-adapted efficient model of care is a dynamic process.
