摘　　要：目的通过数据挖掘分析,探讨恶性肿瘤放射治疗病种住院日的影响因素,以指导合理控制住院日。方法结合文献查阅与专家咨询意见,提取2015年7月-2018年6月某三甲医院恶性肿瘤放射治疗病种的病案首页的相关数据,包括社会学因素、疾病因素、诊疗因素等。应用相应的秩和检验方法对可能影响住院日的变量进行单因素分析,并对筛选出的变量行多因素logistic回归分析。结果共纳入1696例患者(男736例,女960例),住院日为40.5(29.0,49.0)天。单因素分析中,性别、年龄、入院次数、肿瘤类型、伴随疾病、病例分型、操作、同期化疗、31天内再住院计划、医疗组等10个变量对住院日的影响差异有统计学意义(均P<0.05)。多因素logistic回归分析显示:按OR值大小排序,肿瘤类型、同期化疗、医疗组、病例分型、伴随疾病、入院次数等6个因素是住院日长短的独立影响因素。结论恶性肿瘤放射治疗病种住院日受多因素综合影响,不同肿瘤类型、放疗同期进行化疗、不同医疗组诊疗、不同病例分型、有伴随疾病以及入院次数均能影响该病种住院日。Objectives To explore the influencing factors of the length of hospital stay(LOS) for the patients receiving radiotherapy based on data mining, and eventually shorten the LOS. Methods According to the literature review and expert consultation, related data of patients on radiotherapy in a tertiary hospital from July2015 to June 2018 were retrospectively collected. Potential influencing factors of the LOS in this population were screened by rank sum test and then established by a multivariate logistic regression analysis. Results According to univariate analysis, gender, age, number of admissions, type of tumors, concomitant diseases, case classification,operation, concurrent chemotherapy, re-hospitalization plan within 31 days and medical group were significantly correlated with the LOS(P<0.05). According to logistic regression analysis, six factors were independent influencing factors on the LOS,including type of tumors, concurrent chemotherapy, medical group,case classification, concomitant diseases and number of admissions(ordered by odds ratio).Conclusions The LOS for patients receiving radiotherapy was affected by many factors.Among them, type of tumors, concurrent chemotherapy, medical group, case classification, concomitant diseases and number of Admissions were the independent influencing factors.
