Background Remote home monitoring might fill the perceived surveillance gap after hospital discharge. However, it is unclear whether older oncologic patients will be able to use the required new digital technologies. The study aimed to assess the feasibility of postoperative remote home monitoring for this population. Methods This observational cohort study recruited patients aged 65 years or older scheduled for oncologic surgery. The study patients used a mobile application and activity tracker preoperatively until 3 months postoperatively. A subset of the patients used additional devices (thermometer, blood pressure monitor, weight scale) and completed electronic health questionnaires 2 weeks after hospital discharge. Feasibility was assessed by the study completion rate, compliance in using components of the information technology system, acceptability [Net Promotor Score (NPS)] and usability [System Usability Scale (SUS)]. The NPS score varied from − 100 to + 100. An SUS higher than 68 was considered above average. Results Of 47 participants (mean age, 72 years; range, 65–85 years), 37 completed a follow-up assessment, yielding a completion rate of 79%. Compliance in using the activity tracker ( n  = 41) occurred a median of 81 days [interquartile range (IQR), 70–90 days] out of 90 post-discharge days. Compliance in measuring vital signs and completing health questionnaires varied from a median of 10.5 days (IQR, 4.5–14.0 days) to 12 days (IQR, 5–14 days) out of 14 days. The NPS was + 29.7%, and the mean SUS was 74.4 ± 19.3. Conclusion Older oncologic patients in the study considered postoperative home monitoring acceptable and usable. Once they consented to participate, the patients were compliant, and the completion rate was high.
