Informative censoring by health plan disenrollment among commercially insured adults.
Informative censoring by health plan disenrollment among commercially insured adults
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.
