|Equation||(# individuals screened) x (% individuals getting screened solely because of the program) x (# QALY increase) x ($ QALY)|
|Explanation||This metric estimates the impact of Type 2 diabetes screening leading to improved health, estimated in terms of quality-adjusted life years (QALY).
Number of individuals screened: Reported by program.
Percentage of participants screened solely because of the program: [0.1]. This is based on the Minnesota Department of Health estimate that around 1 in 10 individuals with diabetes are not diagnosed (Minnesota Department of Health, 2016).
QALY increase: [0.02]. This estimate is for the screening of patients for Type 2 diabetes from the Centers for Disease Control and Prevention, Diabetes Cost-Effectiveness Group (1998) and Engelau, Narayan & Herman (2000), which indicate that the QALY for diabetes screening can, on average, be estimated at about 0.02.
$ value per QALY: [$50,000]
Benefits are then discounted to present value based on the average age of participation to life expectancy.
