Objectives: Technology can now be used through patient engagement platforms (PEPs) to allow patients to interact with their healthcare providers in order to increase education, assess and manage symptoms, monitor outcomes, and address questions/concerns. The objective of this study was to evaluate the impact of a mobile health patient engagement platform (PEP) on postoperative outcomes among gynecologic oncology patients undergoing surgery on an enhanced recovery protocol (ERP). Methods: All gynecologic oncology patients undergoing surgery on the ERP were approached from July 2019 to May 2021. The patients were enrolled in a PEP, which can be accessed by computer, tablet, or smartphone and provide enhanced pre and postoperative patient education and remote patient monitoring. Patients who elected to participate were provided with targeted education based on their age and comorbid conditions and were asked to complete daily health checks in the postoperative period. Patients reporting problems in the health check were given personalized education for minor problems or prompted to call the healthcare team for more serious issues. Age, race, body mass index (BMI), Carlson comorbidity index (CCI), surgical complexity, insurance status, length-of-stay (LOS), re-admission rates, surgical site infections, and use of the PEP were evaluated. Analysis was performed using SPSS v.26. Results: A total of 682 women met inclusion criteria during the study time. Of them, 347 were in the PEP group and 335 were in the control group (ERP only group). Patients in the PEP group had a significantly lower LOS (2.9 vs 3.6 days; p<0.01) and lower re-admission rate (4.3% vs 8.6%; p<0.01) than the control group. There was no difference in surgical site infections (1.1 vs 0.9%; p=0.4). Demographics and other factors, including race, BMI, CCI, gynecologic cancer diagnosis, surgical complexity, and insurance status, were not different between the PEP and control groups. Conclusions: The use of PEP in our gynecologic oncology patient population decreased LOS by nearly one day despite an absence of differences in other demographic and surgical factors. Furthermore, there was a 50% reduction in re-admission rates in the PEP group. The use of PEP allows healthcare professionals to engage, evaluate, and treat patients in a way that improves perioperative care.
