Primary Care and Adolescent Immunization for Rochester

Study Overview
=================
Brief Summary
-----------------
This study will examine whether the implementation of an outreach program that employs a tracking/reminder/recall/home visiting strategy will have any impact on receipt of immunizations and preventive care among urban adolescents.

Detailed Description
-----------------
Outreach workers will be placed at 9 primary care pediatric and family medicine practices throughout one urban area. Adolescent patients at these 9 practices will be identified and then randomized into two groups; (1) those receiving outreach intervention during Year 1 of the study and (2) those receiving outreach intervention during Year 2 of the study. Randomization will be stratified by practice site, patient age, and patient gender. After randomization, the list of Year 1 subjects will be distributed to the appropriate outreach worker. The outreach worker will track the immunization status of 11-15yo patients within their practice, identify patients who are eligible for but have not yet received immunizations recommended for their age group (MMR, Varicella, Hepatitis B, HPV, Meningococcal Conjugate, Tdap) and/or a well child visit within the past year, and then attempt to connect these patients with medical care through three levels of outreach activity. First level of outreach activity involves contacting the parent/guardian of the patient by telephone. Outreach workers will attempt to inform patient's parent/guardian of needed immunizations/preventive visit and facilitate the scheduling of a medical appointment. If unable to successfully complete the task through telephone contact, outreach workers will initiate the second level of outreach activity - contact by mail. If contact by mail is unsuccessful, the third and most intense level of outreach activity will be implemented. The outreach worker will attempt to notify the patient's parent/guardian of need for immunization/preventive appointment by visiting the patient's listed home address. During this visit, the outreach worker will attempt to inform the parent/guardian of recommended immunizations, provide information pertaining to these immunizations, facilitate appointment scheduling, and assist patient in compliance with scheduled medical appointment Interventions directed towards the subjects of the Year 1 group will cease after 15 months of outreach activity. A chart review of intervention and control groups will be conducted to determine immunization and well child visit rates within the two groups. At this time, the tracking/reminder/recall/home visiting strategy employed with the Year 1 group will be repeated for Year 2 subjects.
