Abstract:Objective：To investigate the effect of comprehensive nursing under the core concept of multidimensional crisis control concept on perioperative psychological stress and complications of elderly patients undergoing endoscopic retrograde cholangiopancreatography（ERCP）. Methods：A total of 98 elderly patients who underwent ERCP in our hospital from October 2019 to January 2022 were selected and divided into observation group（n=53）and control group（n=45）by simple random method. The control group received routine nursing intervention，and the observation group received all-round nursing under the JCI core concept，and continued intervention until the patients were discharged. The postoperative recovery indicators（hospitalization time，first time out of bed，and first anal exhaust time） of the two groups of patients were recorded.Before and after intervention，depression and anxiety were assessed by Hamilton Depression Scale（HAMD）and Hamilton Anxiety Scale（HAMA），and exercise of self-care agency scale（ESCA），and pain was assessed by visual analog scale（VAS）. The incidence of postoperative complications and patient care satisfaction were compared between the two groups. Results：The hospitalization time，first time out of bed and first anal exhaust time of patients in the observation group were significantly shorter than those in the control group（P < 0.05）. After intervention，the scores of HAMD，HAMA and VAS in observation group were significantly lower than those in control group（P < 0.05）. After the intervention，the ESCA and positive coping scores of both groups increased，and the negative coping scores decreased. The ESCA and positive coping scores of the observation group were higher than those of the control group，while the negative coping scores of the observation group were lower than those of the control group（P < 0.05）. At 2 h，6 h，and 12 h after surgery，the VAS scores of the observation group were significantly lower than those of the control group（P < 0.05）；the incidence of complications in the observation group was 15.09%，which was significantly lower than the 40.00% of the control group（P < 0.05）. The nursing satisfaction of the observation group was higher than that of the control group（92.45% vs 77.78%）（P＜0.05）. Conclusion：Multidimensional crisis control concept is beneficial to improve the mental state，changing coping styles，and alleviating pain levels of elderly ERCP patients，reduce the incidence of complications，and promote patients to recover quickly.
