Abstract:Objective To observe the application effect of IDEAS model visit intervention on patients with colonic polyps undergoing endoscopic mucosal resection (EMR). Methods A total of 137 patients with colonic polyps who were treated by EMR in the Second Affiliated Hospital of Chengdu Medical College from January 2021 to December 2022 were selected as the research subjects. According to the randomization method, the patients were divided into the control group (68 cases) and the observation group (69 cases). Both groups were given routine nursing intervention, and the observation group was given extra IDEAS model visit intervention. The perioperative basic conditions (surgical time, hospital stay, incidence rate of postoperative complications), and coping styles ［Simplified Coping Style Questionnaire (SCSQ)］ and quality of life ［Short Form 12-Item Survey (SF-12)］scores before and after intervention were compared between the two groups of patients. Results There was no statistical difference in surgical time between the two groups (P＞0.05). The hospital stay［(3.07±0.34) d vs (3.48±0.51) d, t=5.544, P＜0.01］and incidence rate of postoperative complications［18.84% vs 35.29%, χ²=4.703, P＜0.05］ in the observation group were lower than those in the control group, and the differences were statistically significant. After intervention, the SCSQ positive coping dimension score and the total score of SF-12 scale in the observation group were increased compared with those before intervention (P＜0.05), and the above scores were higher compared to the control group （19.25±4.13 vs 16.60±3.72, 71.78±8.88 vs 66.62±8.90, P<0.01). The score of negative coping dimension of SCSQ scale in observation group was reduced compared with those before intervention (P<0.05), and the score in observation group was lower than that in control group (10.83±4.08 vs 12.94±4.32, P<0.01). Conclusion IDEAS model visit intervention can shorten the hospital stay, and reduce the incidence rate of postoperative complications. It can increase positive coping styles and enhance the quality of life, which has high clinical application value.
