Current Studies

  1. Adolescent Depression Screening in Pediatric Primary Care: An Examination of Case Disposition and Racial and Ethnic Disparities
    Goal: The aim of this retrospective cohort study is to examine screening for depression and case disposition for youth with depressive symptoms in the primary care setting across two health care systems. Using electronic health record data, the study will examine the frequency of depression screening among adolescents (ages 12-17) in pediatric primary care. Among adolescents with positive depression screening, the study will examine referral and mental health treatment receipt. Finally, the study will examine racial and ethnic group differences in screening referral, and treatment.

  2. Vaccine Safety Datalink (VSD) InfrastructureGoal: Kaiser Permanente Mid-Atlantic States (KPMAS) is collaborating with CDC and the VSD network of health care organizations to conduct ongoing surveillance of vaccine safety. KPMAS is developing a local data infrastructure that facilitates monitoring of adverse events following vaccination, and collaborating on or leading vaccine safety monitoring and evaluation studies.
