Abstract：
OBJECTIVE: Indwelling urinary catheter is closely associated with the occurrence of urinary tract infection (UTI). Herein, we further explored the correlation of urinary catheter indwelling time and UTI.
METHODS: Retrospectively, the medical data of nosocomial patients (n = 681) were collected during two quarters of April 2023 to June 2023 (the second quarter, 23.4-23.6, n = 330) and July 2023 to September 2023 (the third quarter, 23.7-23.9, n = 351). The baseline data and incidence of catheter-related UTI were analysed. The total hospitalisation days and indwelling urinary catheter days of patients in five departments were assessed, namely, coronary care unit (CCU), respiratory intensive care unit (RICU), surgical intensive care unit (SICU), neurology intensive care unit (NICU) and cardiac surgical intensive care unit (CSICU) departments. The correlation between hospitalisation days/indwelling urinary catheter days and the occurrence of UTI was evaluated by Spearman correlation analysis.
RESULTS: In the CCU, RICU, SICU, NICU and CSICU departments, the number of patients was 463, 83, 29, 91 and 15, respectively. During 23.4-23.6, the incidence of catheter-associated UTI (CAUTI) was 0, 2.85, 6.12, 0 and 12.99 per 1000 urinary catheter days in CCU, RICU, SICU, NICU and CSICU, respectively. During 23.7-23.9, the incidence of CAUTI was 2.98, 6.13, 8.66, 0 and 0 per 1000 urinary catheter days in CCU, RICU, SICU, NICU and CSICU, respectively. Notably, hospitalisation days/indwelling urinary catheter days were positively correlated with the occurrence of CAUTI in each quarter (p < 0.05).
CONCLUSIONS: There was a positive correlation between urinary catheter indwelling time and the occurrence of UTI.

摘要：
目的：留置导尿管与尿路感染(UTI)的发生密切相关。在这里，我们进一步探讨了导尿管留置时间与UTI的相关性。
方法：回顾，医院患者的医疗数据(n=681)是在2023年4月至2023年6月的两个季度收集的(第二季度，23.4-23.6，n=330）和2023年7月至2023年9月（第三季度，23.7-23.9，n=351）。分析基线数据和导管相关UTI的发生率。评估五个科室患者的总住院天数和留置导尿管天数,即,冠心病监护病房(CCU),呼吸重症监护病房(RICU),外科重症监护病房(SICU),神经内科重症监护病房(NICU)和心脏外科重症监护病房(CSICU)。采用Spearman相关性分析评价住院天数/留置导尿管天数与UTI发生的相关性。
结果：在CCU中，RICU,SICU,NICU和CSICU部门，患者人数分别为463,83,29,91和15.在23.4-23.6期间，CCU中导管相关UTI（CAUTI）的发生率为每1000个导尿管天数0、2.85、6.12、0和12.99。RICU,SICU,NICU和CSICU,分别。在23.7-23.9期间，在CCU中，每1000个导尿管天的CAUTI发生率为2.98、6.13、8.66、0和0。RICU,SICU,NICU和CSICU,分别。值得注意的是,住院天数/留置导尿管天数与各季度CAUTI发生率呈正相关(p<0.05).
结论：导尿管留置时间与尿路感染的发生呈正相关。
