Comparative Effectiveness Trial of Two Reminder/Recall Methods to Increase Immunization Rates in Young Children

Summary

The purpose of this study is to determine if a collaborative centralized population-based reminder/recall intervention is more effective than a traditional practice-based reminder/recall intervention at increasing immunizations among young children.

Conditions

• Immunization Rates

Interventions

BEHAVIORAL

Collaborative Pop-Based R/R: Phone/Mail Group

Within each county, half of patients will be randomized to a phone/mail group (2 auto-dialer calls and 2 postcards) and the other half of patients will be put in a mail-only group (4 mailings). The following collaborative approaches will be utilized: patient addresses and phone numbers will be updated prior to recall for electronic Flat File Format practices; all notices to parents (auto-dialer calls and mailings) will appear to come both from the local public health department and providers who choose to have their name listed; all bad addresses and phone numbers will be updated by calling the last provider of care. Up to 4 notices will be sent to parents of children who are still not up to date for recommended immunizations.

BEHAVIORAL

Collaborative Pop-Based R/R: Mail-Only Group

Parents will receive up to four mailings if their child appears in need of immunizations according to CIIS. The Collaborative method is the same as in the auto-dialer/mail group; however patients in this group will not receive telephone calls.

BEHAVIORAL

Practice-based Recall

All practices will receive training on how to conduct practice-based recall using CIIS and educational materials to use within their practices to promote compliance with the infant vaccination schedule. Individual practices will make their own decisions about the extent to which they follow the recommendations and implement recall within their practice. Although the study team will not provide them with any additional interventions, we will track any other interventions they independently do (websites, newsletters, telephone) in order to assess the effect of these additional interventions.
