Effect of prehabilitation on postoperative outcomes in the frail older people: A systematic review and meta-analysis

Abstract

Objective: The study investigates the impact of preoperative rehabilitation on the surgical prognosis of frail older patients.

Method: The effect sizes of all studies retrieved and included by the nine databases were analyzed and expressed as RR and WMD.

Results: 8 studies with 902 participants met the criteria for inclusion. A significant reduction in total complications (RR = 0.84, 95 % CI = 0.73 to 0.97, P = 0.021) and the 6MWT after surgery (WMD = 74.76, 95 % CI = 44.75 to 104.77, P = 0.000) was observed in the prehabilitation group. But it had no differences in mortality(RR = 1.89, 95 % CI = 0.75 to 4.72, P = 0.176), readmission rates(RR = 1.04, 95 % CI = 0.56 to 1.91, P = 0.906) and LOS(WMD = -0.24, 95 % CI = -1.00 to 0.52, P = 0.540).

Conclusions: Prehabilitation had positive effect on postoperative complications and functional recovery in frail older patients.
