|Equation||(# participants) x (% individuals screened/treated solely because of the program) x (# QALY increase) x ($ QALY)|
|Explanation||This metric estimates the impact of screening for sexually transmitted diseases (STI) on lifetime health, estimated in terms of quality-adjusted life years (QALY).
Number of participants: Reported by program.
Percentage of participants receiving test/treatment due to program: The counterfactual is based on the percent of low-income female and male individuals who are tested for sexually transmitted illnesses in the U.S.A. An estimated 80% of women are tested and 7% of men (Cuffe, et al.,2016).
QALY increase: [0.4]. Based on findings from Beck, et al. (2016).
$ value per QALY: [$50,000]
Benefits are then discounted to present value based on the average age of participation to life expectancy.
