Abstract
Does HIV/AIDS Funding Undermine Health Systems?
Highlights
The main threat to the validity of this study relates to the assignment of treatment of HIV/AIDS funding to health centers
Even if Shepard and others[1] had enough money to get data for all the HIV/ AIDS health centers and did not have to take a random subset of 25 HIV/AIDS centers, the work by Shepard and others[1] needs to address why these health centers were chosen to receive HIV/AIDS funding to start. It would not be surprising if the government assigned centers to receive HIV/ AIDS funding because those centers were more likely to have better outcomes, or were believed to be more successful or capable before treatment assignment
The work by Shepard and others[1] matches only on three characteristics: (1) health center ownership, (2) performance-based financing, and (3) district income in 2002. This assessment might be reasonable if these were the only three factors on which the treatment was assigned, and if there were no other differences between intervention and control groups that affected the outcomes
Summary
The main threat to the validity of this study relates to the assignment of treatment of HIV/AIDS funding to health centers. It would not be surprising if the government assigned centers to receive HIV/ AIDS funding because those centers were more likely to have better outcomes, or were believed to be more successful or capable before treatment assignment.
