Centralized IIS-based Reminder/Recall to Increase Childhood Influenza Vaccination Rates_2nd Trial in Colorado
Centralized IIS-based Reminder/Recall to Increase Childhood Influenza Vaccination Rates, 2nd Trial in Colorado
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.

Descripción detallada
Annual epidemics of seasonal influenza cause substantial morbidity and mortality in the U.S. with high rates of hospitalizations, emergency department and outpatient visits, and medical costs. Children experience significant morbidity from influenza, and also play a critical role in spreading infection to adults. Since 2010, the Advisory Committee on Immunization Practices (ACIP) has recommended influenza vaccination for all children >6 months of age. However, vaccination rates remain very low-- only 56% of children 2-17 years are vaccinated. Low rates are a concern for both seasonal influenza and in preparation for pandemic influenza. One of the nationally recommended strategies for raising childhood influenza vaccination rates is to use parent reminder/recall (R/R) by phone or mail, which can raise rates by up to 20 percentage points. However, less than 16% of primary care practices use R/R despite many studies showing its effectiveness.
Statewide immunization information systems (IISs) now exist in all states to track childhood vaccinations, but they have not been used for R/R for influenza vaccine because of the lack of evidence for its effectiveness and lack of a template for IIS-based R/R. The investigators have united two leading immunization research groups (Denver, CO and Rochester, NY) to assess the impact of centralized IIS-based influenza vaccine R/R, and to evaluate the effect of two types of R/R (autodial v. mail R/R) over usual care. The investigators will also develop tools to aid other states in creating efficient IIS R/R systems for seasonal and possible pandemic influenza outbreaks.
In Colorado, evaluate the impact of (a) autodialer reminders and (b) mailed messages versus standard-of-care control on raising influenza vaccination rates among children 6m-17 years of age.
The investigators propose a 3-arm RCT study design with the following study arms:
- Standard of care control
- Autodialer (3 reminders)- with brief education message + practice name + practice phone #
- Mailed reminder (3 reminders)-- with brief education message + practice name + practice phone #

Receipt of at least 1 influenza vaccine according to immunization records in the Immunization Information System (IIS) records in each state
Periodo de tiempo: 6 months

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.
