DescriptionPURPOSE
In the United States, influenza infection is estimated to hospitalize 200,000 people and cause 36,000 deaths each year. Healthy People 2020 has set a goal of 70% vaccination rate per season for adults; however seasonal influenza rates continually fall short of this goal, with 38.5% of adults over the age of 18 vaccinated for the 2017-2018 season ("Immunization and Infectious Diseases", n.d.). Text message reminder programs for vaccines have been successful in increasing vaccination rates by way of serving as a reminder and recommendation for vaccination (Jacobson Vann et al., 2018).
METHODOLOGY
An influenza text message reminder program was implemented at an adult primary care practice. Patients were enrolled in September and October 2018 and randomized into intervention and standard care groups based on month of enrollment. A single text message reminder was sent to each cohort, and vaccine receipt was evaluated for each group. Rationales for non-enrollment were collected to identify barriers to enrollment uptake, and a post-study satisfaction survey link was sent via text message.
RESULTS
While most patients did not receive the vaccine, more individuals in the intervention group (26.7%, n=4) received the flu vaccine than the standard care group (15.4%, n=2). A Fisher's Exact test was used to examine any correlations between the intervention groups, demographic factors, and vaccine receipt. No significant association was found between intervention group and text message receipt, but there was a significant association between female gender and vaccine uptake. Of the 42 non-enrollment rationales, 19% stated they did not want to be vaccinated, 40.4% were ineligible due to prior vaccination or planned vaccination at current appointment, and 23.8% declined to provide a reason for non-enrollment. The post-intervention survey data had minimal response, likely due to message failure.
IMPLICATIONS FOR PRACTICE
Future studies would also seek to expand on this project, perhaps with a larger sample size and incorporation of an educational intervention for vaccination. Increasing vaccination rates is vital to the health of the population, and further study on these types of reminder interventions would contribute greatly to primary care practice.
