Population Versus Practice-based Interventions to Increase Immunizations

NCT01296906 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 31567

Last updated 2013-06-21

No results posted yet for this study

Summary

One of the nation's major health priorities, as outlined in Healthy People 2010, is to increase the proportion of children aged 19 to 35 months who have received all universally recommended vaccines. This study will compare two interventions for increasing immunization rates in this age group, one using well-studied primary care practice-based methods and the other using innovative technologies to increase immunization rates at the population-level. Results of this study will provide data that will be relevant nationally in guiding future investment of resources to increase up-to-date rates in young children prior to school entry.

Hypothesis: Population-based approaches will be more effective than practice-based interventions at increasing immunizations among 19-35 month olds.

Interventions

BEHAVIORAL

Recall conducted by private practices

All practices in these counties will receive training on practice-based R/R using the Colorado Immunization Information System (CIIS or immunization registry). Practices will receive a recommended schedule for conducting recall in 19-35 month children 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 informational systems) in order to assess the effect of these additional interventions.

BEHAVIORAL

Recall conducted centrally by local health department

A centralized recall of children 19-35 months will be conducted through local health departments. CIIS will identify a cohort of 19-35 month olds with an who are in need of an immunization and will coordinate up to 3 mailers to children who are not current for recommended immunizations.
