根治性膀胱切除术后患者再入院的强度依据患者自身及医疗护理系统的影响而不同。因此,研究者进行了基于人口的研究,以探讨根治性膀胱切除后再住院强度增加的相关因素。研究者使用SEER(监测,流行病学和最终结果)-Medicare数据,确定了1 782例从2003年至2009年行根治性膀胱切除术的患者,并以住院时间长度(d)来定义再入院强度,住院时间以四分法分为短于3d(最低)、3~5d、5~7d及7d以上(最高),采用Logistic回归检验与再住院强度相关的因素。结 The intensity of readmission after radical cystectomy varies depending on the patient and the medical care system. Therefore, the researchers conducted a population-based study to explore the factors associated with increased hospitalization after radical cystectomy. Using the SEER-Medicare data, the researchers identified 1 782 patients undergoing radical cystectomy from 2003 to 2009 and defined the length of hospital stay (d) to define readmission Intensity and length of hospital stay were divided into three quarters for shorter than 3 days (lowest), 3 ~ 5 days, 5 ~ 7 days and 7 days (highest), and Logistic regression was used to test the factors related to the strength of rehospitalization.
