Home to Stay: A Randomized Controlled Trial Evaluating the Effect of a Postdischarge Mobile App to Reduce 30-Day Readmission Following Elective Colorectal Surgery

A randomized controlled trial was conducted to evaluate the effect of a postdischarge app on 30-day readmissions and patient-reported outcomes following colorectal surgery.Patients undergoing colorectal surgery are particularly vulnerable during their transition from hospital-to-home. There has been increasing interest in e-health to provide cost-effective transitional care. An integrated discharge monitoring program using a mobile app platform was developed to support patients after surgery.A 2 arm, superiority randomized control trial was conducted at an academic tertiary care center with patients undergoing elective colorectal surgery. The intervention group received usual postoperative care and postdischarge monitoring with the app. The primary outcome was 30-day readmissions following hospital discharge.Two hundred eighty-two participants were randomized. The majority were young, had inflammatory bowel disease and underwent laparoscopic surgery. Intention to treat analysis showed no difference between groups for 30-day readmission (14.8% vs 17.6%, P=0.55), ER visits (25.0% vs 28.8%, P=0.49), primary care visits (12.5% vs 8.8%, P=0.34) or unplanned healthcare visits (34.4% vs 35.2%, P=0.89). All patient reported outcomes were significantly improved with median scores higher with the app for satisfaction [9, interquartile range (IQR): 8-10 vs 8, IQR: 7-9, P=0.001], well-being (7, IQR: 6-8 vs 6, IQR: 5-7, P=0.001) and significantly lower for anxiety (3, IQR: 2-5 vs 5, IQR: 3-6, P=0.001).Although the app did not show a significant reduction in 30-day readmission or ER visits, it did lead to significant improvements in patient-reported outcomes. The app may be an important tool to support patients following colorectal surgery.
