Objective To construct a perioperative exercise program for older frail patients with colorectal cancer,and to verify its effect. Methods Based on Goal-directed Theory and literature review,expert consultation was carried out to establish the perioperative exercise program for older frail patients with colorectal cancer. Then,from July to December 2022,the perioperative exercise program was established for older frail patients with colorectal cancer hospitalized in the General Surgery Department of a tertiary A hospital in Suzhou by convenience sampling method for preliminary application. It was divided in to the intervention group and the control group by the ward. The intervention group was applied with the constructed perioperative exercise program on the basis of routine perioperative nursing. The safety, feasibility and intervention effect of the program were evaluated. Results 15 experts were included for 2 rounds of expert consultations. The authority coefficient was 0.880;the coefficient of variation was <0.250;the Kendall concordance coefficient was 0.167 and 0.224,respectively. The final program contained 4 stages:preoperative exercise, postoperative bed rest,sitting and standing exercise. In the end,54 specific interventions were constructed. During the preliminary application,all the patients completed the program. Generalized estimation equation showed that, on the interaction effect, there was no statistical difference(P=0.752);there were significant differences on the intervention effect and the time effect(P<0.05). At discharge,there were significant differences in timed up and go test and Barthel Index between the 2 groups(P<0.05). Only 2 patients experienced mild pain in the intervention group,and no other adverse events occurred. Conclusion The perioperative exercise program for older frail patients with colorectal cancer,based on Goal-directed Theory,is scientific, reliable and safe. It has been preliminarily verified in improving postoperative physical function,activities of daily living and early postoperative recovery of elderly frail patients with colorectal cancer.
