Abstract

OBJECTIVES

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 ( < 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。在此，我们进一步探讨了导尿管留置时间与 UTI 的相关性。

方法

回顾性收集 2023 年 4 月至 6 月（第二季度，23.4-23.6，n=330）和 7 月至 9 月（第三季度，23.7-23.9，n=351）两个季度期间住院患者（n=681）的医疗数据。分析患者的基线数据和导管相关性 UTI 的发生率。评估五个科室（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]、神经重症监护病房[NICU]和心脏外科重症监护病房[CSICU]）患者的总住院天数和留置导尿天数。采用 Spearman 相关分析评估住院天数/留置导尿天数与 UTI 发生的相关性。

结果

在 CCU、RICU、SICU、NICU 和 CSICU 科室中，患者人数分别为 463、83、29、91 和 15。在 23.4-23.6 期间，CCU、RICU、SICU、NICU 和 CSICU 科室的导管相关性尿路感染（CAUTI）发生率分别为 0、2.85、6.12、0 和 12.99/1000 导尿天数。在 23.7-23.9 期间，CCU、RICU、SICU、NICU 和 CSICU 科室的 CAUTI 发生率分别为 2.98、6.13、8.66、0 和 0/1000 导尿天数。值得注意的是，每个季度的住院天数/留置导尿天数与 CAUTI 的发生呈正相关（<0.05）。
