Changes in Frailty prevalence
With both the Fried scale and the CFS, the prevalence of the different frailty groups significantly changed 6 months after surgery with respect to their baseline distribution (p<0.01).
Figure 3 shows the differences in the prevalence of frailty, before and 6 months after surgery. The direction of these changes was towards a decrease in the overall burden of frailty in the entire cohort of patients. In this way, the patients classified as frail with the Fried scale went from 27.5% in the preoperative period to 17% after 6 months of follow-up. On the CFS scale, the most remarkable change occurred in vulnerable patients, who decreased from 39.5 to 22%.
