The Task Force finding is based on evidence from a Community Guide systematic review published in 2000 (search period 1980-1997) combined with more recent evidence (search period 1997-2009). The systematic review was conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to increasing appropriate vaccination.
Previous Review (search period 1980–1997)
Twenty-nine intervention studies qualified for the systematic review.
Updated Evidence (search period 1997–2007)
Nineteen additional studies were identified in the search period considered in this update. Of these, 15 studies provided common measurements of change in vaccination rates or coverage.
- Median increase in vaccination coverage:
- Overall: 10 percentage points (15 studies)
- Provider reminders alone: 12 percentage points (5 studies)
- Provider reminders with additional components: 10 percentage points (10 studies)
Studies from the updated search period evaluated the effectiveness of provider reminders in a range of different client and provider populations, healthcare settings, and for different vaccines.
