Increasing Appropriate Vaccination: Client Reminder and Recall Systems

Client reminder and recall interventions involve reminding members of a target population that vaccinations are due (reminders) or late (recall). Reminders and recalls differ in content and are delivered by various methods—telephone, letter, postcard, or other. Most reminder systems involve a specific notification for a specific client, and may be accompanied by educational messages regarding the importance of immunization for the targeted vaccine.

Summary of Task Force Recommendations and Findings

The Community Preventive Services Task Force recommends reminder and recall interventions based on strong evidence of effectiveness in improving vaccination coverage:

  • In children and adults
  • In a range of settings and populations
  • When applied at different levels of scale from individual practice settings to entire communities
  • Across a range of intervention characteristics (e.g., reminders and recall, content, theoretical basis and method of delivery)
  • When used alone or with additional components

Task Force Finding and Rationale Statement

 

Results of the Original and Updated Systematic Reviews

The Task Force recommendation is based on evidence from an original review (search period 1980-1997) and an updated review (search period 1997-2007). Updates of reviews are conducted to incorporate more recent evidence.

Learn more about the original review and Task Force finding in the Vaccinations to Prevent Diseases section of our publications page.

Original Review (search period 1980–1997)

Forty-two studies qualified for the original systematic review.

Updated Review (search period 1997–2007)

Twenty studies were identified in the search period considered in this update.

  • Median increase in vaccination coverage:
    • Overall: 6.1 percentage points (20 studies)
    • Client reminder and recall alone: 5.1 percentage points (12 studies)
    • Client reminder and recall combined with additional components: 10 percentage points (8 studies)
  • Reviewed studies evaluated the effectiveness of client reminder and recall interventions in a wide range of client and provider populations and settings.

These updated results were based on a recent systematic review of available studies, by a team of specialists in systematic review methods, and experts in research, practice and policy related to vaccinations to prevent diseases.
