Increasing Appropriate Vaccination: Health Care System-Based Interventions Implemented in Combination
Task Force Finding
The Community Preventive Services Task Force recommends health care system-based interventions implemented in combination on the basis of strong evidence of effectiveness in increasing vaccination rates in targeted client populations.
Based on findings from 37 of the 64 included studies, the Task Force further recommends a combination of interventions that include the following:
At least one intervention to increase client demand for vaccinations, such as:
And one or more interventions that address either, or both, of the following strategies:
- Interventions to enhance access to vaccinations:
- Interventions directed at vaccination providers or systems:
The interventions listed as examples for each strategy were those that showed the greatest effect on vaccination rates.
Read the full Task Force Finding and Rationale Statement for details including implementation issues, possible added benefits, potential harms, and evidence gaps.
Health care system-based interventions implemented in combination involve the use of two or more coordinated interventions to increase vaccination rates within a targeted client population. Interventions are implemented primarily in health care settings, although efforts may include additional activities within the community. Specific interventions may include client reminder and recall systems; clinic-based client education; expanded access in health care settings; provider assessment and feedback; provider reminders; and standing orders. The selection and implementation of coordinated interventions may result from an overall quality improvement effort in a health care setting.
About the Systematic Review
This Task Force finding is based on evidence from a Community Guide systematic review completed in 2010 (62 studies; search period 1980-2010) combined with more recent evidence (2 studies; search period 2010-February 2012).
It updates and replaces the 2010 finding for Health System-Based Interventions Implemented in Combination.
The 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.
The systematic review included 64 studies with 76 study arms.
- Overall change in vaccination rates from the combination of at least two interventions: median increase of 9.0 percentage points (interquartile interval [IQI]: 4 to 21 percentage points; 58 studies, 70 study arms)
- Increases in vaccination rates were larger when implemented in settings with low rates at baseline.
- Change in vaccination rates from the combination of at least one intervention each from two or more strategies: median increase of 17.0 percentage points (IQI: 6 to 27 percentage points; 37 studies, 44 study arms)
- Studies were conducted in urban (34 study arms), rural (1 study arm), and mixed urban, suburban, and rural (9 study arms) settings.
- Interventions targeted children (29 study arms), adolescents (2 study arms), adults (14 study arms) and older adults (22 study arms).
- Studies evaluated the following vaccines:
- Childhood recommended (24 study arms)
- Influenza - child (5 study arms)
- Influenza – adult (27 study arms), child (1 study arm)
- Pneumococcal - adult (19 study arms)
- Tetanus booster (4 study arms)
- Adolescent recommended (1 study arm)
- Nearly one-third of the studies evaluated interventions that targeted populations with low socioeconomic status (22 study arms).
Based on the settings and populations from included studies, results are applicable to the following;
- Interventions were implemented in a range of clinical settings, communities, and client populations
- Combined approaches were effective when delivered to:
- Children ages 12 years and younger
- Adults ages 18 to 65 years
- Older adults ages 65 years and older
- Urban settings
- For different vaccines, including:
- Childhood vaccination series
- Pneumococcal –adults and children
- Influenza – adults and children
- Tetanus booster
The five studies that qualified for the economic review assessed various combinations of provider reminders, standing orders, provider assessment and feedback, provider education, and provider incentives. All monetary values are reported in 2012 U.S. dollars.
- The median intervention cost per person per year was $4 (IQI: $0.84 to $13; 4 studies)
- The mean cost per additional vaccinated person was $12, ranging from $6 to $21 (3 studies)
- One study evaluated an intensive intervention that included home visits to immunize and care for newborns. The cost reported in this study is considered an outlier and was not included in the cost estimates provided above.
Considerations for Implementation
The Task Force also recommends community-based interventions implemented in combination giving decision-makers a range of options to consider when selecting and coordinating interventions to meet local needs and resources.
