目的 调查重症胰腺炎患者非计划重返ICU的现状特征，并分析其危险因素，为避免胰腺炎患者重返ICU提供理论依据。方法 回顾性分析2020年1月1日—2024年2月1日在浙江省某三级甲等综合医院4个院区中自ICU转到普通病房的298例主要诊断为重症胰腺炎患者的病例资料，统计非计划重返ICU率，收集患者的一般资料、疾病相关资料，按照是否发生非计划重返ICU分为重返组和未重返组，采用单因素及Logistic回归分析筛选非计划重返ICU的危险因素。结果 298例患者中共有47例重返ICU，重返率15.8%。二分类Logistic回归分析显示：年龄（OR=1.039）、基础疾病个数（OR=1.244）、合并呼吸衰竭（OR=3.283）是重症胰腺炎患者非计划重返ICU的独立危险因素。结论 该组重症胰腺炎患者非计划重返ICU处于较高水平。为避免高危患者重返ICU，临床需重点关注高龄、基础疾病复杂、合并呼吸衰竭的患者。

Objective To investigate the clinical characteristics and status of unplanned return to the ICU for patients with acute pancreatitis in general wards，and analyze risk factors to provide a theoretical basis for preventing ICU readmissions. Methods A retrospective analysis was conducted on the medical records of 298 patients primarily diagnosed with acute pancreatitis，transferred from the ICU to general wards between January 1，2020，and February 1，2024，from 170 wards in four campuses of a tertiary hospital in Zhejiang Province. The unplanned ICU return rate was calculated，and patient demographics and disease-related information were collected. According to the occurrence of unplanned return to the ICU，the patients were divided into the return to the ICU group and the non-return to the ICU group. Univariate and logistic regression analyses were employed to identify risk factors for unplanned readmissions. Results Among the 298 patients，47 experienced returns to ICU，resulting in a rate of 15.8%. Binary logistic regression showed that age（OR=1.039），number of comorbidities（OR=1.244），and presence of respiratory failure（OR=3.283） were independent risk factors for unplanned ICU return in acute pancreatitis patients. Conclusion The rate of unplanned return to ICU among acute pancreatitis patients was relatively high in this group of patients. Clinicians should pay special attention to patients with advanced age, complex comorbidities and heart failure，thereby preventing return to ICU.
