Overview
Brief Summary
Previous studies have shown that low-cost, behavioral nudges through texting can increase influenza vaccination uptake compared to usual care. However, there are limited studies that evaluate the effect of decreasing barriers to scheduling, especially within safety net populations. The setting for this study, DHS, is the second largest public delivery system in the country and serves approximately half a million diverse patients that are eligible for vaccinations annually. This pilot study (one arm in a larger randomized controlled trial) will examine the effect of text messages highlighting MediCal health plan transportation resources (vs standard text messaging) on influenza vaccination rates in adults during the 2022-2023 flu season.

Outcomes
Primary Outcomes
Number of Participants Vaccinated at the End of the Campaign Period
Time Frame: 6 months
Number of Participants who received their influenza vaccination during the campaign period, as measured in the California Immunization Registry (CAIR2) to include vaccinations occurring both inside and outside the LADHS system. We assessed baseline vaccination status at the beginning of the flu season and excluded individuals who already received their vaccination.
Secondary Outcomes
- Heterogeneity of Treatment Effects for Demographics(6 months)
