Vaccination Programs: Home Visits to Increase Vaccination Rates
Summary of CPSTF Finding
The CPSTF notes, however, that economic evidence shows home visits can be resource-intensive and costly relative to other options.
Intervention
Interventions may be directed to everyone in a designated population (e.g., low-income single mothers), or to those who have not responded to other intervention efforts, such as client reminder and recall systems.
Programs may be implemented alone or as part of a larger healthcare system or community-based program to increase vaccination rates.
CPSTF Finding and Rationale Statement
About The Systematic Review
This review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice and policy related to increasing appropriate vaccination.
Context
Summary of Results
The systematic review included 23 studies. Of these, 20 studies with 21 study arms used a common measure of change in vaccination rates.
- Overall vaccination rates increased by a median of 11 percentage points (20 studies with 21 study arms).
- Home visits led to meaningful improvements in vaccination rates when used in the following ways:
- With all clients in a designated population (12 study arms)
- With only clients who did not respond to other interventions (9 study arms)
- When focused on vaccinations alone (12 study arms)
- When used to address vaccinations and other health concerns (9 study arms)
- When vaccinations were provided on-site (8 study arms)
- When clients were referred to vaccination services outside the home (13 study arms)
- As the sole intervention (8 study arms)
- As part of a larger healthcare system or community-based program (13 study arms)
Summary of Economic Evidence
Findings from the economic review show that home visits are resource-intensive and high-cost interventions relative to other available options.
Nine studies were included in the review (search period: 1980 – 2012). Monetary values are in reported in 2013 US dollars.
- The median for intervention group size was 575 (9 studies)
- Median cost per person was $56.30 (9 studies)
- Median cost per additional vaccinated person was $786.79 (9 studies)
- Studies were conducted in the United States (5 studies), the United Kingdom (2 studies), Australia (1 study), and Canada (1 study).
- One study looked at adolescent vaccines; eight studies evaluated interventions focused on the childhood vaccination series.
Applicability
- Urban settings
- Lower income populations
- Children and adults
- Influenza and childhood vaccinations
Evidence Gaps
- What are the effectiveness and economic benefits of this intervention among adolescent populations or when used in rural settings?
- What portion of home visits can be attributed solely to improving vaccination rates when home visits include other activities and objectives?
Study Characteristics
- Included studies were conducted primarily in urban settings (15 studies) and among lower income populations (10 studies).
- Studies were directed at children (15 studies) and adults (7 studies)
- Evaluated interventions addressed influenza vaccinations (7 studies) and childhood vaccinations (14 studies).
Analytic Framework
Effectiveness Review
When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

Search Strategies
Effectiveness Review
The CPSTF findings are based on studies included in the original review (search period 1980-1997) combined with studies identified in the updated search (search period 1997- February 2012). Reference lists of articles reviewed as well as lists in review articles were also searched, and members of our coordination team were consulted for additional references.
Details of the original search (1980-1997)
The following five electronic databases were searched during the original review period of 1980 up to 1997: MEDLINE, Embase, Psychlit, CAB Health, and Sociological Abstracts. The team also reviewed reference lists in articles and consulted with immunization experts. To be included in the review, a study had to:
- have a publication date of 1980 1997;
- address universally recommended adult, adolescent, or childhood vaccinations;
- be a primary study rather than, for example, a guideline or review;
- take place in an industrialized country or countries;
- be written in English;
- meet the evidence review and Guide chapter development team’s definition of the interventions; provide information on one or more outcomes related to the analytic frameworks; and
- compare a group of persons who had been exposed to the intervention with a group who had not been exposed or who had been less exposed. In addition, we excluded studies with least suitable designs for two interventions (provider reminder/recall and client reminder/recall) where the literature was most extensive.
Details of the update search (1997- February 2012)
The team conducted a broad literature search to identify studies assessing the effectiveness of Vaccine Preventable Disease interventions in improving vaccination rates. The following nine databases were searched during the period of 1997 up to February 2012: CABI, CINAHL, The Cochrane Library, EMBASE, ERIC, MEDLINE, PSYCHINFO, Soci Abs and WOS. Reference lists of articles reviewed as well as lists in review articles were also searched, and subject matter experts consulted for additional references. To be included in the updated review, a study had to:
- have a publication date of 1997- February 2012;
- evaluate vaccinations with universal recommendations;
- meet the evidence review and Guide chapter development team’s definition of the interventions;
- be a primary research study with one or more outcomes related to the analytic frameworks;
- take place in an high income country or countries;
- be written in English
- compare a group of persons who had been exposed to the intervention with a group who had not been exposed or who had been less exposed. In addition, we excluded studies with least suitable designs for two interventions (provider reminder/recall and client reminder/recall) where the literature was most extensive

Economic Review
The present review included studies that reported economic outcomes from the 2000 review (search period 1980-1997) combined with studies identified from updated searches (search period 1997- February 2012) within the standard medical and health-related research databases, Google Scholar, and databases specialized to economics and social sciences. The details of the two sets of searches are provided below.
Details of the Updated Search (1997- February 2012)
The team conducted a broad literature search to identify studies assessing interventions to improve vaccination rates. The following nine databases were searched during the period of 1997 up to February 2012: CABI, CINAHL, The Cochrane Library, EMBASE, ERIC, MEDLINE, PSYCHINFO, Soci Abs and WOS. In addition, Google Scholar and specialized databases (CRD-University of York: NHS EED, EconLit, and JSTOR), were also searched. Reference lists of articles reviewed as well as lists in review articles were also considered, and subject matter experts consulted for additional references.

Considerations for Implementation
- Home visits that serve multiple purposes (e.g., parent education, home safety assessment, vaccination promotion) may be logistically challenging.
- Timing for vaccinations and other home visit services may be difficult (i.e. seasonal influenza and childhood series).
- Clients may not open their homes to strangers because of security or privacy concerns.
- Resource-intensive interventions such as home visits may be necessary to increase vaccination rates among populations with very low vaccination rates or communities where disparities in coverage persist. Interventions are likely to cost less if used as part of a stepped approach that begins with something less resource-intensive such as client reminder and recall systems.
- Included studies noted that home visits give providers additional opportunities to assess clients’ undetected health risks or medical problems.
- Although no specific harms were identified in the included studies, potential harms described in the literature include difficulties managing clients who have adverse reactions to vaccinations, and stigmatization of socially or economically disadvantaged clients who are identified as needing special services.
