研究概览
简要总结
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.

研究组 & 干预措施
Population-based Reminder/Recall
Recall is performed centrally by public health departments for all children in need of immunizations in a geographic area.
干预措施: Recall conducted centrally by local health department (Behavioral)
Practice-based Reminder/Recall
Reminder/Recall is performed by individual private practices for their patients who appear in need of immunizations.
干预措施: Recall conducted by private practices (Behavioral)
结局指标
主要结局
Evaluate effectiveness of population-based reminder/recall methods versus practice-based reminder/recall methods in 14 Colorado counties (rural and urban)
时间窗: 6 months post-intervention (December 2010)
The primary outcome measures will be: 1) change in up-to-date rates from baseline levels 6 months after the intervention (T-1) for 19-35 month olds in population-based compared to practice-based intervention counties and 2) percent of children who were not up-to-date prior to recall (T-0) who received any additional new vaccine in each type of intervention county.
