Tulane STAR (Sending Texts, Advancing Results): impact of text messaging on bariatric post-operative protocol compliance

BACKGROUND: Text messaging is frequently employed in the outpatient setting to communicate with or send reminders to patients. However, there is a paucity of literature on the impact of text messaging on inpatient care. In this study, the use of text messaging in hospitalized patients is evaluated by assessing patient compliance to a post-operative bariatric protocol. METHODS: This was a randomized controlled trial that studied compliance to a post-operative bariatric protocol in patients who underwent bariatric surgery at a tertiary, academic medical center between February and May 2021. Patients were randomized to either the control group, in which they received standard post-operative education alone or the Tulane Sending Texts, Advancing Results (STAR) intervention arm, in which participants received the same post-operative education along with two text message reminders to drink water, use their incentive spirometers, and ambulate (per post-operative instructions) on post-operative day (POD) # 0 and POD # 1. The primary outcome was compliance with the protocol, defined as the number of 1-oz cups of water consumed, incentive spirometry usage, and ambulation frequency and distance. Secondary outcomes include length of stay and complications. RESULTS: A total of 35 patients were enrolled in the study (17 control, 18 STAR intervention). There was no significant difference in age, BMI, or type of surgery performed between the two groups. Clear liquid consumption was significantly higher in the STAR intervention group with an average of 27.7 ± 3.5 cups as compared to 18.2 ± 8.9 in the control group (p < 0.001). Similarly, statistically significant increases in incentive spirometry usage (p < 0.01) and ambulation distance and frequency (p < 0.02) were observed in the STAR intervention group. CONCLUSIONS: While patients are in the hospital, text messaging can improve compliance to post-operative protocols. Peri-operative text messaging can enhance patient education and communication.
