Older Veterans are increasingly undergoing surgery and are at particularly high risk of postoperative morbidity and mortality. Prehabilitation has emerged as a method to improve postoperative outcomes by enhancing the patient's preoperative condition. We present data from our prehabilitation pilot project and plans for expansion and dissemination of a nationwide quality improvement effort. The infrastructure of the existing Veterans Affairs (VA) Gerofit health and exercise program was used to create our pilot. Pilot patients were screened for risk of postoperative functional decline, assessed for baseline physical function, enrolled in a personalized exercise program, and prepared to transition into the hospital for surgery. Patients (n = 9) completed an average of 17.7 prehabilitation sessions. After completing the program, 55.6% improved in ≥2 of the 5 fitness assessments completed. Postoperative outcomes including complications, 30-day mortality, and 30-day readmissions were better than predicted by the National Surgical Quality Improvement Program Surgical Risk Calculator. We have obtained institutional support for implementing similar prehabilitation programs at VA hospitals nationally through our designation as a VA Patient Safety Center for Inquiry. This is the first multi-institutional prehabilitation program for frail, older Veterans and represents an essential step toward optimizing surgical care for this vulnerable population.
