Feasibility of an Image-Based Mobile Health Protocol for Postoperative Wound Monitoring

Surgical site infection (SSI) is the most common nosocomial infection and the leading cause of readmission among surgical patients. Many SSI develop in the post-discharge period and are inadequately recognized by patients. To address this, we developed a mobile health protocol of remote wound monitoring using smartphone technology. The current study aims to establish its feasibility among patients and providers. Study Design We enrolled vascular surgery patients during their inpatient stay. They were trained to use our mobile health app, which allowed them to transmit digital images of their surgical wound and answer a survey regarding their recovery. Following hospital discharge, participants completed the app daily for two weeks. Providers on the inpatient team reviewed submissions daily and contacted patients for concerning findings. Results Forty participants were enrolled. Forty-five percent of participants submitted data every day for two weeks, with an overall submission rate of 90.2%. Submissions were reviewed within an average of 9.7 hours of submission, with 91.9% of submissions reviewed within 24 hours. We detected 7 wound complications with one false negative. Participant and provider satisfaction was universally high. Conclusions Patients and their caregivers are willing to participate in a mobile health program aimed at remote monitoring of postoperative recovery, and they are able to complete it with a high level of fidelity and satisfaction. Preliminary results indicate the ability to detect and intervene on wound complications.


Surgical site infections are the most common hospital-acquired infection, costing an estimated $3 to $10 billion annually, and a leading cause of hospital readmission. We demonstrate the feasibility and preliminary effectiveness of an image-based smartphone protocol for the early detection of surgical site infections and the prevention of hospital readmission.
