Microbiological diagnostics is of great importance in limiting the spread of nosocomial infections. The information on etiological agents of infections and their susceptibility to antibiotics enables a quick response in the case of a suspected epidemic outbreak. The aim of this study is to analyze the incidence of nosocomial urinary tract infections among patients hospitalized in hospital wards over a period of 2 years and to determine the predominant etiological agent depending on the method of clinical specimen collection. Data from the Mazovian Specialist Hospital (MSH) in Radom constitute the material for the preparation of this study. Urine was collected using two methods. The first one was the method of collecting urine from the central stream, while the second method was urine collected from patients with a urinary catheter in place. The statistical calculations were conducted using the statistical software. Based on hospital data, it was shown that 5,870 urine tests were performed during the period under review, of which 2,070 were positive. The number of positive results in 2021 decreased by 2.84% compared to that in 2020. On the basis of the statistical analysis, differences in the occurrence of multiple strains were observed between catheter-based and midstream urine collection. Differences were observed especially for , , , and , , and were significantly more frequently found in urine samples collected through the catheter than from the midstream. Furthermore, (51.56%) and (25.46%) were more frequent when collected from the middle stream than when urine was collected through a catheter. However, for the strain , the results were comparable when urine was collected from catheterized patients (13.83%) and from midstream (13.35%). Urinary tract infection among hospitalized patients of the Mazovian Specialist Hospital in Radom was diagnosed quite frequently. In 2021, 32 more urine cultures were performed than in 2020. In the analyzed period, among all ordered urine cultures, 35.27% of samples were positive.
微生物诊断在限制医院感染的传播方面非常重要。有关感染病原体及其对抗生素的敏感性的信息可在疑似疫情爆发时快速做出反应。本研究的目的是分析在 2 年内住院病房中发生的医院获得性尿路感染的发生率，并根据临床标本采集方法确定主要病原体。该研究的材料来自拉多姆的马佐夫舍专家医院（MSH）。尿液采集采用两种方法。第一种是从中流收集尿液的方法，第二种是从带有导尿管的患者中收集尿液的方法。统计计算使用统计软件进行。根据医院数据，在审查期间共进行了 5870 次尿液检查，其中 2070 次为阳性。与 2020 年相比，2021 年阳性结果数量减少了 2.84%。基于统计分析，在基于导管和中流尿液采集的情况下，观察到多种菌株发生的差异。在导管和中流尿液样本中观察到差异，特别是在 、 、 、 、 、 和 。通过导管收集的尿液样本中明显更频繁地发现 ， ， ， 和 ，而从中流收集的尿液样本中 ， ， 和 更频繁。此外，从中流收集的尿液样本中更频繁地发现 （51.56%）和 （25.46%），而通过导管收集的尿液样本中则较少。然而，对于菌株 ，从中流收集尿液（13.35%）和从导管化患者收集尿液（13.83%）的结果相当。拉多姆的马佐夫舍专家医院住院患者的尿路感染诊断相当频繁。2021 年比 2020 年多进行了 32 次尿液培养。在分析期间，在所有订购的尿液培养物中，有 35.27%的样本为阳性。
