Malawi HIV programme cuts could save costs but increase AIDS deaths
An individual-based health-system simulation model assessed HIV programme changes in Malawi from 2025 to 2050. Reducing testing or removing viral-load monitoring saved resources but increased projected AIDS deaths and disability-adjusted life years (DALYs).
- Modelled reductions span 2025–2050 in Malawi.
- Halving testing projected 55,200 additional AIDS deaths.
- Removing viral-load monitoring projected 21,460 additional deaths.
- Combined cuts saved most, but worsened health outcomes.
Researchers used the Thanzi La Onse individual-based health-system simulation model to compare HIV testing, treatment monitoring, prevention and tuberculosis preventive therapy strategies with a scenario maintaining end-2024 service levels. The model projected health outcomes, healthcare-worker time and programme costs in Malawi over 2025–2050.
Cutting HIV testing by 50% was projected to save 26.45 million healthcare-worker-hours and USD 538.9 million, while adding about 55,200 AIDS deaths (95% uncertainty interval [UI], 35,100–78,000) and 3.28 million DALYs (95% UI, 2.41–4.54 million). Removing viral-load monitoring was associated with 21,460 additional deaths (95% UI, 12,400–31,700), 1.17 million additional DALYs and USD 108.9 million in savings. A combined reduction in testing, monitoring and prevention had the largest cost savings, USD 812 million, but was projected to add 80,960 AIDS deaths and 4.56 million DALYs.
The model suggests that reducing diagnosis and treatment monitoring could undermine epidemic control despite near-term resource savings. These are projections, not observed outcomes; results depend on model assumptions, and the analysis holds other services and workforce supply fixed. The authors conclude that testing and treatment monitoring should be maintained when HIV programmes are reconfigured.
In practice
For clinicians and programme planners in Malawi, the model projects substantial health losses if HIV testing or treatment monitoring is reduced: halving testing was associated with about 55,200 additional AIDS deaths, while removing viral-load monitoring was associated with about 21,460. The findings support preserving these services in programme reconfiguration discussions, but do not establish observed effects or prove that results will occur in practice. Projections cover 2025–2050 and rely on model assumptions, including fixed delivery of other health services and workforce supply.
