- Registration Number
- NCT01390363
- Lead Sponsor
- Boston Children's Hospital
- Brief Summary
The purpose of this study is to determine whether contacting the parents of adolescents overdue for routine vaccines or contacting both the parents AND adolescents overdue to routine vaccines improves immunization rates as compared to usual care.
- Detailed Description
This randomized controlled trial is a 3-armed study designed to evaluate an immunization recall system in adolescents. In the control arm (Group 1), the adolescents will receive usual care, in which they will primarily receive immunizations at annual physical exams, or as recommended by providers at urgent care visits. In one intervention arm (Group 2), the parent/guardian will receive a telephone call informing them that the adolescent is overdue for one or more immunizations (conjugated Neisseria meningitidis (MCV4) vaccine, tetanus-diphtheria-pertussis (Tdap) booster, and/or the second varicella (VZV) vaccine). In the second intervention arm (Group 3), both the parent/guardian and the adolescent will receive a telephone call informing them that the adolescent is overdue for one or more immunizations. Immunization rates will be compared between the 3 groups at a four week and a twelve month follow up period.

- Primary Outcome Measures
Name Time Method receipt of vaccine of interest at 28 days 28 days Vaccination records are assessed 28 days after the intervention to see if Tdap, MCV4, or the 2nd VZV vaccine were administered.
- Secondary Outcome Measures
Name Time Method receipt of vaccine of interest at 1 year 1 year Immunization records are assessed 1 year after the intervention to assess for receipt of Tdap, MCV4, and/or the 2nd VZV vaccine.
receipt of other vaccines at 28 days 28 days Immunization records are assessed 28 days after the intervention to assess for receipt of any vaccine other than Tdap, MCV4, and the 2nd VZV.
receipt of other vaccines at 1 year 1 year Immunization records are assessed 1 year after the intervention to assess for receipt of any vaccine other than Tdap, MCV4, and the 2nd VZV.
receipt of prior vaccines at 28 days 28 days We will assess the immunization record at 28 days to see if it has been updated with vaccines given prior to the enrollment date to see if we successfully obtained copies of immunization records at other healthcare sites.
receipt of prior vaccines at 1 year 1 year We will assess the immunization record at 1 year to see if it has been updated with vaccines given prior to the enrollment date to see if we successfully obtained copies of immunization records at other healthcare sites.
