Brief summary

Although most US adolescents visit their primary care doctor, their immunization rates are low. Primary care practices from two networks, one in upstate New York as well as a national network of pediatric clinics were surveyed to ask what they thought was the best strategy to increase immunization rates. Point-of-care prompts (either by an electronic health record message or by a nurse) when an adolescent patient comes in for any type of visit and is due for a vaccine was chosen. This study will determine if these prompts will increase immunization rates after a 12-month intervention period.

Design outcomes

Primary

Measure	Time frame	Description
Adolescent Immunization Rates	One Year	Bivariate analysis will measure the overall change between the control and intervention groups. Vaccination rates will be summarized using descriptive statistics. As appropriate, two sample t-test or chi-square tests will be used to summarize patient level data. Odds ratio with associated 95% confidence interval will be reported within each of the 2 networks.

Secondary

Measure	Time frame	Description
Missed Opportunities	One Year	A hierarchical logistic regression model will evaluate the intervention effect on rates of missed opportunities.
