Influenza Reminder Text-Messaging

Not Applicable
Completed
Conditions
Influenza
Interventions
Behavioral: Text message reminder
Registration Number
NCT06587984
Lead Sponsor
Children's Hospital of Philadelphia
Brief Summary

Through a large, population-level quality improvement effort within the Children's Hospital of Philadelphia Care Network, we will evaluate text message reminders on flu vaccination rates for both patients with and without a scheduled well child care visit during flu season.

Detailed Description

This is a randomized control trial with two patient cohorts: patients with and without a scheduled well child care visit during the upcoming 2024 flu season. Patients with a scheduled well child visit will be randomized into one of three groups (control, intervention message #1, or intervention message #2). Patients within the intervention groups will receive a one-time text message reminder to get their flu shot for their child at their child's upcoming well visit. Intervention groups will be texted at the same time, the same month as their child's well visit. The text message language will differ between groups. Patients without a scheduled upcoming well child visit during the 2024 flu season will also be randomized into one of three groups (control, intervention message #1, or intervention message #2). Intervention groups will be texted at the same time, at the start of flu season. The text message language will differ between groups.

Flu vaccine uptake will be measured within each patient cohort.

GroupInterventionDescription
Cohort 1bText message reminderPatients within Cohort 1 have an upcoming well child visit between September-December 2024. Patients within Cohort 1b are those randomized to INTERVENTION MESSAGE #1 and will receive text message reminder (variation #1) about getting their flu shot at their upcoming visit.
Cohort 1cText message reminderPatients within Cohort 1 have an upcoming well child visit between September-December 2024. Patients within Cohort 1c are those randomized to INTERVENTION MESSAGE #2 and will receive text message reminder (variation #2) about getting their flu shot at their upcoming visit.
Cohort 2bText message reminderPatients within Cohort 2 do not have an upcoming well visit between September-December 2024, but completed their well visit between January 2023 through August 2024. Patients within Cohort 2b are those randomized to INTERVENTION MESSAGE #1 and will receive text message reminder (variation #3) about getting their flu shot this upcoming flu season.
Cohort 2cText message reminderPatients within Cohort 2 do not have an upcoming well visit between September-December 2024, but completed their well visit between January 2023 through August 2024. Patients within Cohort 2b are those randomized to INTERVENTION MESSAGE #2 and will receive text message reminder (variation #4) about getting their flu shot this upcoming flu season.
Primary Outcome Measures
NameTimeMethod
The effectiveness of a text message reminder on influenza vaccine uptakeBaseline to approximately 30 days post-text message

Via prospective chart review, the primary outcome for both Cohort 1 and Cohort 2 will be to assess the number of patients who received an influenza vaccination 30 days post-text message reminder (baseline). Data from chart review will determine vaccination status (patient received influenza vaccination or not).

Secondary Outcome Measures
NameTimeMethod
The effectiveness of text message language within Cohort 1Baseline to approximately 30 days post-text message

Via prospective chart review, we will compare the number of patients within the Cohort 1 intervention groups who received influenza vaccination to understand which text message variation was more effective. Data from chart review will determine vaccination status (patient received influenza vaccination or not).

The effectiveness of text message language within Cohort 2Baseline to approximately 30 days post-text message

Via prospective chart review, we will compare the number of patients within the Cohort 2 intervention groups who received influenza vaccination to understand which text message variation was more effective. Data from chart review will determine vaccination status (patient received influenza vaccination or not).
