Technologic Transformation of Perioperative Cardiac Care and Outcomes

Ann Thorac Surg. 2023 Aug;116(2):413-419. doi: 10.1016/j.athoracsur.2023.03.024. Epub 2023 Mar 31.


Background: The "Perfect Care" initiative engages, educates, and enrolls adult cardiac surgery patients into a comprehensive program that incorporates remote perioperative monitoring (RPM). This study investigated the impact of RPM on postoperative length of stay, 30-day readmission and mortality, and other outcomes.

Methods: This quality improvement project compared outcomes in 354 consecutive patients who underwent isolated coronary artery bypass and who were enrolled in RPM between July 2019 and March 2022 at 2 centers against outcomes in propensity-matched control patients from a pool of 1301 patients who underwent isolated coronary artery bypass from April 2018 to March 2022 without RPM. Data were extracted from The Society of Thoracic Surgeons Adult Cardiac Surgery Database, and outcomes were analyzed according to its definitions. RPM used perioperative standard practice routines, a digital health kit for remote monitoring, a smartphone application and platform, and nurse navigators. Propensity scores were generated with RPM as the outcome measure, and a 2:1 match was generated using a nearest-neighbor matching algorithm.

Results: Patients who underwent isolated coronary artery bypass and who were participating in RPM showed a statistically significant, 15.4% (1 day) reduction in postoperative length of stay (P < .0001) and a 44% reduction in 30-day readmission and mortality (P < .039) compared with matched control patients. Significantly more RPM participants were discharged directly home instead of to a facility (99.4% vs 92.0%; P < .0001).

Conclusions: The RPM platform and associated efforts to engage and monitor adult cardiac surgery patients remotely is feasible, is embraced by patients and clinicians, and transforms perioperative cardiac care by significantly improving outcomes and reducing variation.
