Fit4Surgery app: Home-based prehabilitation app for older patients undergoing elective colorectal cancer surgery

Abstract

Background

Supervised multimodal prehabilitation prior to colorectal cancer (CRC) surgery is associated with reduced complications and enhanced recovery. However, it is labor intensive and expensive. In an aging population with increasing demand and costs on healthcare and staff shortages, home-based prehabilitation (HBP) with an app could be of interest. This study assessed the effectiveness of a Fit4Surgery app in CRC surgery.

Method

The app was effectuated in a prospective cohort study of 100 CRC patients ≥60 years from October 2021–December 2022. The primary outcome was preservation or improvement of the 6-minute walking test (6MWT) six weeks postoperative, compared to baseline. Secondary outcomes were 90-day complication and mortality rate, 90-day readmission, length of stay, 6MWT and Short Performance Physical Battery (SPPB) at different timepoints and total costs.

Results

Three patients needed urgent surgery, remaining 97 patients (mean age 72) using the app for at least three weeks. The 6MWT was preserved in 74.7 % with a 12.1 m higher mean six weeks postoperative, compared to baseline (p = 0.194). A significant higher 6MWT was observed after prehabilitation and one year postoperative, compared to baseline (p=<0.001). The SPPB was significant higher at all timepoints. Overall 90-day complication rate was 25.8 %, readmission rate 6.3 % and mortality occurred in 2.1 %. Total costs were €518.50 per patient.

Conclusion

This is the first study of multimodal HBP by an app for CRC surgery patients with high compliance. Results show promising results regarding functional capacity and a low occurrence of complications, in line with multimodal supervised prehabilitation. This by reducing costs by half.
