Despite recent international efforts to increase antiretroviral treatment (ART) coverage, it is estimated that more than 5 million people who need ART in developing countries do not receive such treatment. Shortages of human resources to treat HIV/AIDS (HRHA) are one of the main constraints to...

Without large increases in the number of health workers to treat HIV/AIDS (HAHW) many countries in sub-Saharan Africa will be unable to achieve universal coverage with antiretroviral treatment (ART), leading to large numbers of avoidable deaths among people living with HIV/AIDS. We conduct a...

The Indus Basin of Pakistan with 800 hydropower project sites and a feasible hydropower potential of 60GW, 89% of which is undeveloped, is a complex system poised for large-scale changes in the future. Motivated by the need to understand future impacts of hydropower alternatives, this study...

Systematic reviews of health systems research commonly limit studies for evidence synthesis to randomized controlled trials. However, well-conducted quasi-experimental studies can provide strong evidence for causal inference. With this article, we aim to stimulate and inform discussions on...

We quantify the impact of adult deaths on household economic wellbeing, using a large longitudinal dataset spanning more than a decade. Verbal autopsies allow us to distinguish AIDS mortality from that due to other causes. The timing of the lower socioeconomic status observed for households with...

This paper presents a framework for the health system with health workers at the core. We review existing health-system frameworks and the role they assign to health workers. Earlier frameworks either do not include health workers as a central feature of system functioning or treat them as one...

At present, there exists no widely agreed upon set of study-design selection criteria for systematic reviews of health systems research, except for those proposed by the Cochrane Collaboration's Effective Practice and Organisation of Care (EPOC) review group (which comprises randomized...
