Misclassification of Loss to Care Among Persons With Human Immunodeficiency Virus (HIV): Improved Capture of Silent Transfers Through Surveillance Linkage Using Statewide Mandatorily Reported Laboratory Measures

HIV-positive individuals lost to follow-up from particular clinics may not be lost to care (LTC). After linking Vanderbilt's Comprehensive Care Clinic cohort to Tennessee's statewide HIV surveillance database, LTC decreased from 48.4% to 35.0% at 10 years. Routine surveillance-linkage by domestic HIV clinics would improve LTC and retention measure accuracy.
