New Study Reveals Significant Benefits of Prehabilitation in Surgery Patients
A groundbreaking new study suggests that exercise and nutritional prehabilitation can significantly improve surgical outcomes by reducing complication rates and potentially enhancing recovery times among patients preparing for surgery.
Key Findings of the Study
Researchers examined 186 randomized controlled trials involving 15,684 participants, with an average age of 62 years, of whom 45% were women. The study found that exercise prehabilitation was associated with a 50% reduced risk of complications compared to standard care. Nutritional support alone was linked to a 38% decrease in complications. Furthermore, a combination of exercise, nutritional, and psychosocial support decreased the complication risk by 36%.
Dr. Daniel McIsaac, a leader in the Aging Innovation in Perioperative Medicine and Surgery Research Group at the University of Ottawa, noted that while the benefits were expected, the magnitude of the findings was surprising. He highlighted how psychosocial support also played a crucial role in reducing hospital stay times.
The Impact of Exercise, Nutrition, and Psychosocial Support
The review found that exercise alone, with an odds ratio (OR) of 0.50, and nutrition alone, with an OR of 0.62, significantly reduced complications. Combined exercise, nutrition, and psychosocial support, with an OR of 0.64, further enhanced these benefits. Regarding hospital stays, combined exercise and psychosocial support reduced hospital days by 2.44, while combined exercise and nutrition support decreased days by 1.22. Individually, exercise and nutrition reduced hospital stays by 0.93 and 0.99 days, respectively.
Overall, exercise and nutrition were the most effective components across all critical outcomes. Dr. McIsaac emphasized that while the data are promising, more research is needed due to the mixed quality of the studies included in the review.
Expert Opinion
Dr. Michael Englesbe from the University of Michigan commented that, while the study shows consistent positive benefits of prehabilitation, the overall evidence strength is uneven. However, he underlined the small downsides and minimal risks associated with such interventions, suggesting that these activities are beneficial for patients.
Dr. Englesbe’s prior study in Michigan also demonstrated that prehabilitation programs could lead to shorter hospital stays and reduced costs. He stressed the importance of practical, flexible programs that enhance patient compliance and health system feasibility.
Implications for Future Practice
While the results are promising, Dr. McIsaac advised caution, especially for patients new to exercise or those who are not active. He emphasized the need for a supportive health system framework that includes safe, effective, and feasible prehabilitation programs.
As more advanced health systems integrate prehabilitation into preoperative care, the components of a robust prehab program will likely involve exercise, nutrition, and efforts to promote positive psychological well-being.
Conclusion
This systematic review underscores the significant benefits of prehabilitation, including exercise and nutritional support, for reducing surgical complications and improving patient outcomes. The inclusion of psychosocial support further enhances these benefits, particularly in reducing hospital stay times.
As the field advances, more rigorous trials and practical strategies are needed to ensure the widespread adoption of prehabilitation programs that are both effective and accessible.
