## Challenge

Health plan disenrollment in commercial insurance databases occurs frequently and for heterogeneous reasons, but whether disenrollment is informatively censored by health status had not been systematically quantified in a large US commercial claims database.

## Solution

Target RWE and collaborators analyzed 2 million patient-years of commercial insurance data to characterize predictors of within-year and end-of-year disenrollment, finding that within-year disenrollment is driven by health status while end-of-year disenrollment reflects plan characteristics.
