Catheter-associated urinary tract infection (CAUTI) is a frequently reported healthcare-associated infection in critical and non-critical patients. Limited data are available about CAUTI incidence in non-critical patients. We aim to describe the incidence of CAUTI over 9 years and evaluate the impact of the pandemic on the incidence in non-critical acute care patients.
A retrospective observational study of CAUTI in medical-surgical and maternity wards was carried out at a public hospital in the west of the State of Qatar. Data collected included the annual CAUTI incidence (per 1,000 device days), urinary catheter utilization ratio (UC-UR), etiology, and antimicrobial resistance.
115,238 patient days and 6,681 urinary catheters (UC) days were recorded over the study period, and 9 and 4 CAUTI were confirmed in medical-surgical and maternity wards, respectively. The infection rate was 1.9 per 1,000 UC days, and the UC-UR was 0.06. The CAUTI rate was higher in medical-surgical wards over the COVID-19 period (2.4 × 1,000 UC days) in comparison with the non-COVID-19 period (1.7 × 1,000 UC days) (RR 1.46; 1.12-1.80). However, in the maternity ward, the result was 0 and 2.5 × 1,000 UC days during these periods, respectively. No differences were observed in the infection rate among periods for all patients (RR 1.06; 0.81-1.31). Multidrug-resistant organisms were identified in 7 patients, and non-multidrug-resistant in 6 cases.
The study findings describe a lower CAUTI risk over 9 years in non-critical acute care patients. The impact of COVID-19 on the CAUTI risk is mainly related to medical patients who had previously been admitted to critical care. The infection control program should consider these data as a benchmark for quality improvement.
导尿管相关尿路感染（CAUTI）是重症和非重症患者中经常报告的医疗相关感染。关于非重症患者CAUTI发病率的数据有限。我们旨在描述9年期间CAUTI的发病率，并评估大流行对非重症急性护理患者发病率的影响。
在卡塔尔国西部的一家公立医院对内科、外科和产科病房的CAUTI进行了一项回顾性观察研究。收集的数据包括年度CAUTI发病率（每1000个导尿管日）、导尿管使用率（UC-UR）、病因和抗菌药物耐药性。
在研究期间记录了115238个患者日和6681个导尿管日，在内科、外科和产科病房分别确诊了9例和4例CAUTI。感染率为每1000个导尿管日1.9例，UC-UR为0.06。与非COVID-19时期（每1000个导尿管日1.7例）相比，COVID-19时期内科、外科病房的CAUTI率更高（每1000个导尿管日2.4例）（相对危险度1.46；1.12-1.80）。然而，在产科病房，这两个时期的结果分别为每1000个导尿管日0例和2.5例。所有患者各时期的感染率未观察到差异（相对危险度1.06；0.81-1.31）。7例患者鉴定出多重耐药菌，6例为非多重耐药菌。
研究结果表明，非重症急性护理患者在9年期间CAUTI风险较低。COVID-19对CAUTI风险的影响主要与先前入住重症监护病房的内科患者有关。感染控制计划应将这些数据作为质量改进的基准。
