Study Summary
This study is the second trial related to ClinicalTrials.gov ID: NCT02761551. There are slight changes to methods and a different cohort will be used, thus justifying a 2nd ClinicalTrials.gov submission. This trial is taking place in New York State (not NYC) and in Colorado. Each state has it's own ClinicalTrials.gov submission. Despite U.S. guidelines for influenza vaccination of all children starting at age 6 months, only about half of children are vaccinated annually leading to substantial influenza disease in children and spread of disease to adults. A major barrier is that families are not reminded about the need for their children to receive influenza vaccination. The investigators will evaluate the impact of patient reminder/recall (R/R) performed by state immunization information systems to improve influenza vaccination rates by using three clinical trials in two states. The investigators will assess effectiveness and cost-effectiveness of: 1) autodialer reminder/recall versus 2) postcard reminder/recall versus 3) usual care (no R/R) on improving influenza vaccination rates. The investigators will disseminate the state immunization information system based reminder/recall system to all states for use for both seasonal and pandemic influenza vaccinations with the goal of lowering influenza morbidity.
Primary Outcome
Based on our prior studies, we currently plan to send up to 3 autodialer or postcards (based on randomization arm) reminders, spaced every 5 weeks, beginning in early October, and ending mid-December 2017. Outcomes are assessed at 6 months using IIS data.
