An increasing body of information suggests that preoperative physical activity level can impact postoperative outcomes. We sought to investigate this relationship in patients undergoing ventral hernia repair (VHR).
The Abdominal Core Health Quality Collaborative registry was used to identify patients undergoing a VHR between 2013 and 2019. Patient-reported preoperative exercise level was used to stratify the study population into 4 groups: none (no reported exercise), sporadic (once a month), moderate (once per week), and intense (more than once per week). Multi-variate logistic regression analyses were used to assess the impact of preoperative exercise frequency on postoperative outcomes, including complications, hospital readmissions and length of stay. Changes in quality of life and pain from baseline to 30-days postoperatively were assessed using the Hernia-Related Quality of Life Survey and National Institutes of Health Patient-Reported Outcomes Measurement Information System 3A Pain Scale.
A total of 2,994 patients were included in the study, out of which 1,519 (50.7%) patients reported no preoperative exercise, 662 (22.1%) sporadic exercise, 467 (15.6%) moderate exercise, and 346 (11.6%) intense exercise. A total of 1,253 patients (19.2%) experienced a postoperative complication, out of which 249 (3.8%) had a surgical site infection. After multi-variable analysis and adjusting for demographics, comorbidities, and hernia characteristics, increasing exercise frequency (versus no reported exercise) was associated with significantly lower odds of experiencing any postoperative complication (sporadic: odds ratio 0.70; P = .008; moderate: odds ratio 0.62, P = .006; intense: odds ratio 0.67, P = .04), as well as lower odds of readmission (sporadic: odds ratio 0.04; moderate: odds ratio 0.40; intense: odds ratio 0.03; P = .01). Exercise level was not associated with length of stay (sporadic: P = .36; moderate: P = .19; intense: P = .95). No significant differences were found in changes in quality of life or pain from baseline to 30-days after surgery (Hernia-Related Quality of Life Survey, P = .24; National Institutes of Health Patient-Reported Outcomes Measurement Information System 3A P = .14).
Patients reporting greater exercise frequency before surgery demonstrated decreased risk of complications and readmission after undergoing ventral hernia repair. Increasing preoperative exercise participation through targeted prehabilitation programs may be a viable way for patients to reduce complications associated with VHR and improve their postoperative recovery.
