Overview
Brief Summary
The investigators will design and implement a randomized clinical trial to test, on a community-wide level, the effectiveness of managed care based tracking/reminder/recall on improving vaccination coverage among adolescents.
The investigators propose a randomized controlled trial to evaluate the effectiveness of reminder/recall for adolescents: 10,599 adolescents within the managed care organization (MCO) will be randomized into one of three arms: 1) mailed reminders, 2) autodialer telephone messages or 3) standard of care of their practice (no messages from the intervention).
Hypothesis 1: Reminder/recall will increase the receipt of immunizations and preventive services
Hypothesis 2: Telephone (autodialer) reminders will be more effective than mailed reminders
Hypothesis 3: The impact of reminders will be greatest for the most high-risk subgroups which have low baseline immunization rates.
Hypothesis 4: Mailed reminders will be more costly (and less effective) than telephone reminders.
