About

This study will assess the impact of automated reminders for the 6 month and 12 month vaccine visits to increase vaccination in parents experiencing logistic barriers to vaccination.

Full description

Parents of children less than 11 months of age will be identified as delayed or missing vaccinations due to logistic barriers in the Kaiser Permanente Colorado population. Parents identified will be randomized to the intervention arm or the usual care arm. Those in the intervention arm will receive automated reminders for the 6 month and 12 month vaccine visits. Reminders will include scheduling information as well as access to a website with vaccine and scheduling information. They will also have an opportunity to provide preferences in how they receive the automated reminders (text, phone or email). There will be 2 reminders before the 6 and 12 month visits and 2 after the 6 and 12 month visits. Parents will be excluded from receiving reminders if they have received vaccines within the time frame when they are eligible to receive another vaccine or have a well child visit scheduled.

Usual Care
No Intervention group
Description:
Parents will receive usual care for their child at Kaiser Permanente Colorado. This includes recommendations for well child visits at 2, 4, 6 and 12 months of age as well as automated reminders for age eligible children to receive the flu shot during flu season.
Reminders
Experimental group
Description:
Parents randomized to the reminder arm will receive automated reminders to complete a 6 month and 12 month vaccine visit for their child. They will receive 2 reminders before the child is 6 and 12 months of age and 2 reminders after their child is 6 and 12 months of age. Reminders will not occur if they have received vaccines within the eligible time frame to receive a vaccine or have a visit scheduled. After randomization, participants in the intervention arm will have an opportunity to provide their preference on how they receive reminders (text, phone and/or email). Participants not providing a preference will receive text reminders. If a child is randomized into the study after the child is 7 months of age, the parent will only be eligible for reminders for the 12 month vaccine visit.
