Nigerian clinical pharmacy researcher Dr AbdulMuminu Isah has presented new evidence suggesting that differentiated service delivery (DSD), an approach that tailors HIV care to client needs, was associated with improved outcomes among adults living with HIV in a semi-urban Nigerian community, with results indicating strong retention in care and viral load suppression alongside notable patient-reported outcomes.

Isah, whose expertise spans clinical pharmacy, infectious-disease therapeutics, and health-outcomes research, delivered the findings as lead presenter of a mixed-methods assessment titled “Mixed-methods assessment of health outcomes of differentiated service delivery among adults living with HIV in a semi-urban Nigerian community: clients and clinicians’ perspectives.” The work examined DSD’s impact using both routine service data and participant feedback, highlighting how care models affect treatment continuity and the lived experience of people receiving HIV services.

According to the results highlighted in the presentation, DSD was linked to improvements across clinical and humanistic measures, reinforcing the role of implementation design in strengthening HIV outcomes in resource-constrained settings. Isah’s analysis also connected these outcomes to practical realities of care delivery: how services are organised, accessed, and sustained, rather than focusing solely on institutional performance.

The presentation was delivered at the 12th International AIDS Society (IAS) Conference on HIV Science (IAS 2023), held in Brisbane, Australia, from July 23 to 26, 2023, a major global forum where researchers and practitioners share advances shaping HIV science and service delivery worldwide.
