Cost-Utility Analysis of Three U.S. HIV Linkage and Re-engagement in Care Programs from Positive Charge.

Linking and retaining people living with HIV in ongoing, HIV medical care is vital for ending the U.S. HIV epidemic. Yet, 41-44 % of HIV+ individuals are out of care. In response, AIDS United initiated Positive Charge, a series of five HIV linkage and re-engagement projects around the U.S. This paper investigates whether three Positive Charge programs were cost effective and calculates a return on investment for each program. It uses standard methods of cost utility analysis and WHO-CHOICE thresholds. All three projects were found to be cost effective, and two were highly cost effective. Cost utility ratios ranged from $4439 to $137,271. These results suggest that HIV linkage to care programs are a productive and efficient use of public health funds.
