ABSTRACT
PURPOSE:
To evaluate if nudges delivered by text message prior to an upcoming primary care visit can increase influenza vaccination rates.DESIGN:
Randomized, controlled trial.SETTING:
Two health systems in the Northeastern US between September 2020 and March 2021.SUBJECTS:
74,811 adults.INTERVENTIONS:
Patients in the 19 intervention arms received 1-2 text messages in the 3 days preceding their appointment that varied in their format, interactivity, and content.MEASURES:
Influenza vaccination.ANALYSIS:
Intention-to-treat.RESULTS:
Participants had a mean (SD) age of 50.7 (16.2) years; 55.8% (41,771) were female, 70.6% (52,826) were White, and 19.0% (14,222) were Black. Among the interventions, 5 of 19 (26.3%) had a significantly greater vaccination rate than control. On average, the 19 interventions increased vaccination relative to control by 1.8 percentage points or 6.1% (P = .005). The top performing text message described the vaccine to the patient as "reserved for you" and led to a 3.1 percentage point increase (95% CI, 1.3 to 4.9; P < .001) in vaccination relative to control. Three of the top five performing messages described the vaccine as "reserved for you." None of the interventions performed worse than control.CONCLUSIONS:
Text messages encouraging vaccination and delivered prior to an upcoming appointment significantly increased influenza vaccination rates and could be a scalable approach to increase vaccination more broadly.Palavras-chave
