NCT03294473

Brief Summary

This study is related to a previous study, Clinicaltrials.gov ID: NCT02924467. There are some modifications in relation to the intervention arms as well as the use of a different cohort, thereby justifying the second submission to Clinicaltrials.gov. This trial is taking place in New York State, through partnership with the New York State Health Department (excluding New York City), and Colorado. Each state will have it's own Clinicaltrial.gov submission -- this was decided as some of the intervention components are different enough that separate registrations were warranted. Despite U.S. guidelines for influenza vaccination of all children starting at 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 4 clinical trials (2 per state) in two different states. The investigators will assess effectiveness and cost-effectiveness of 1) autodialer R/R 2) text messages R/R 3) mailed postcard R/R as compared to 4) standard of care control (no R/R).

Outcome Measures

Primary Outcomes (1)

  • The primary outcome is receipt of influenza vaccine comparing effectiveness of standard of care control to autodialer, text message and postcard R/R

    Based on our prior studies, we plan to send up to 3 autodialer, text messages or postcards (based on randomization) reminders, roughly every 5-6 weeks. This will begin in October 2017 and end in December 2017. Outcomes are assessed at 6 months using IIS data.

Secondary Outcomes (1)

  • Cost of the R/R intervention

    6 months

Study Arms (4)

Autodial R/R

EXPERIMENTAL

R/R Autodialers:Participants in this group will receive up to 3 influenza vaccination reminders via telephone call - with a brief educational message + practice name + practice phone number

Behavioral: R/R - Autodialers

Text Message R/R

EXPERIMENTAL

R/R Texting: Participants in this group will receive up to 3 influenza vaccination reminders via text message - with a brief educational message + practice name + practice phone number

Behavioral: R/R - Texting

Postcard R/R

EXPERIMENTAL

R/R Mailed Postcard:Participants in this group will receive up to 3 influenza vaccination reminders via postcard - with a brief educational message + practice name + practice phone number

Behavioral: R/R - mailed postcard

Standard of Care Control

NO INTERVENTION

Participants in this group will not receive any influenza vaccination reminders

Interventions

Investigators will send out flu vaccine reminder recall notices via autodialer message to the parents of children 6 months - 17 years of age who are due for the flu vaccine, per the records in the New York State Immunization Information System (NYSIIS).
