|Equation||(# participants) x (% of participants who receive treatment solely because of the program) x (# QALY increase) x ($ QALY)|
|Explanation||This metric estimates the impact of mental health care access and treatment on lifetime health, estimated in terms of quality-adjusted live years (QALY). This metric should be used in conjunction with HEA021.
Number of participants: Reported by program.
Percentage of participants receiving treatment solely because of program: [54%]. This is estimated by Constellation Fund staff based on data from SAMHSA (2017), which shows that 46% of individuals under 200% of the federal poverty level with any mental illness receive mental health care.
QALY increase: [0.16]. This is based on findings from Ising, et al. (2016) which estimated the impact of treatment on QALY over a 4-year period.
$ value per QALY: [$50,000]
Benefits are then discounted to present value based on the average age of participation to life expectancy.
