Prevalence of frailty was 27.5% with the Fried Frailty Scale and 11% with the Clinical Frailty Scale. Even though frail patients presented a higher incidence of postoperative major complications than their robust counterparts, up to 50% of frail patients improved their frailty status after surgery. The distribution of frailty groups at baseline and six months after surgery changed significantly, decreasing the overall burden of frailty after surgery. Besides, robust patients showed a slightly worsening of their previous frailty scores.
