Gains and limitations of a connected tracking solution in the perioperative follow-up of colorectal surgery patients.

The means to target shorter hospital stay include information technology strategies to improve communication between caregivers and patients in order to limit potentially avoidable readmissions. The aim of the present study was to analyse the benefits and limitations of a smartphone-based connected tracking solution in the perioperative follow-up of colorectal surgery patients. This was a retrospective monocentric cohort study of consecutive patients after colorectal surgery between February and December 2018. The mobile health application included information delivery and daily structured questionnaires on a personalized patient electronic profile, before the hospital stay and for 7 days post-discharge. The medical team answered automatic alerts in real time. A total of 93 eligible patients were approached and 36 had to be excluded (26 no smartphone, five no email, five not French speaking). Among the potential users, 50 (88%) engaged in an mHealth app and seven refused. Of these 50 patients, seven dropped out. Of the remaining 43 patients, the app detected 12 adverse events, and 10 (83%) were handled through the app. Healthcare providers responded to patient-generated alerts after a median time of 90 min (range 9-448 min). Patients' mean satisfaction level was 4 ± 0.97 out of 5. In total, 88% of smartphone-equipped patients showed a willingness to engage in mHealth. Reasons for exclusion were the absence of connection tools and a language barrier. Patients who responded to the survey were satisfied with the solution and 83% of post-discharge adverse events were solved through the app, avoiding emergency consultations
