Influenza
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The effectiveness of a text message reminder on influenza vaccine uptake | Baseline 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
| Measure | Time frame | Description |
|---|---|---|
| The effectiveness of text message language within Cohort 1 | Baseline 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 2 | Baseline 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). |
