Engagement and Adherence with a Web-Based Prehabilitation Program for Patients Awaiting Abdominal Colorectal Surgery

Abstract

Understanding the drivers of patient engagement and adherence is critical to developing and implementing preoperative optimization programs. The aim of this project is to determine whether existing health beliefs are associated with engagement and adherence in a home-based online prehabilitation program. Patients undergoing abdominal colorectal operations were enrolled in an online nutrition and exercise program. We collected baseline health beliefs and mindsets, daily exercises, and weekly diet recalls. Multivariable binary logistic regression predicted engagement, multivariable ordinary least squares regression predicted diet adherence, and generalized linear models with a binomial distribution predicted engagement and exercise adherence. Of the 227 patients who agreed to participate, 75% activated their accounts; of those, 75% used the program. Engagement with the program was unrelated to health beliefs or mindsets. Positive diet-related health beliefs and a growth mindset were associated with positive diet behaviors and inversely associated with negative diet behaviors. Exercise-related health beliefs and mindsets were not associated with exercise adherence. Patients enrolled within 4 weeks of surgery used the program more than those enrolled more than 4 weeks from surgery. This app-based prehabilitation program demonstrated moderate acceptability, engagement, and adherence. Addressing health beliefs and mindsets may be an effective way of increasing adherence to diet recommendations. To increase adherence to exercise recommendations, further assessment of potential barriers is critical. While an online platform is a highly promising scalable strategy, more customization and user engagement are necessary to make it an effective way of delivering a preoperative health behavior change intervention.
