摘要

导言:泌尿系统症状是女性患者向全科医生咨询的主要原因。尿液浸量棒测试是诊断尿路感染(UTI)的基石,但传统的目测判读可能会出现偏差。尿液浸量棒检测的自动设备已成为常规替代方法,但有关其准确性的证据仍然有限。因此,我们的目的是比较目测和自动尿液测厚仪判读的一致性,并确定它们在预测细菌尿方面的测试特性:我们进行了一项前瞻性验证研究,研究对象包括全科成年患者的尿液样本,这些样本被送往马斯特里赫特医疗中心 + 进行尿液培养。对每份样本都进行了尿液量尺检测,并通过肉眼自动判读。我们计算了 Cohen's κ 和一致性百分比,并使用 2 × 2 表计算检验特征:我们共采集了 302 份尿样。目测和自动分析结果显示,亚硝酸盐和白细胞酯酶的检测结果几乎完全一致(分别为κ = 0.82和κ = 0.86),但红细胞的检测结果一致性一般(κ = 0.51)。对临床相关(亚硝酸盐和/或白细胞酯酶阳性)样本的解释几乎完全一致(κ = 0.88)。以尿培养为金标准的尿液量尺显示出相似的检测特性,目测和自动判读的灵敏度分别为 0.92 和 0.91,特异性分别为 0.37 和 0.41:结论:自动分析和目测量杯分析在预测菌尿方面显示出近乎完美的一致性和相似的表现。然而,自动分析需要维护,偶尔会出现测量误差。

Comparing visual and automated urine dipstick analysis in a general practice population.

Introduction: Urinary symptoms constitute the primary reason for female patients to consult their general practitioner. The urinary dipstick test serves as a cornerstone for diagnosing urinary tract infections (UTIs), yet traditional visual interpretation may be subject to variability. Automated devices for dipstick urinalysis are routinely used as alternatives, yet the evidence regarding their accuracy remains limited. Therefore we aimed to compare concordance between visual and automated urinary dipstick interpretation and determine their test characteristics for the prediction of bacteriuria.

Material and methods: We conducted a prospective validation study including urine samples originating from adult patients in general practice that were sent to the Maastricht Medical Centre + for urinary culture. Urinary dipstick tests were performed on each sample, which were interpreted visually and automatically. We calculated Cohen's κ and percentage agreement and used 2 × 2 tables to calculate test characteristics.

Results: We included 302 urine samples. Visual and automated analysis showed almost perfect agreement (κ = 0.82 and κ = 0.86, respectively) for both nitrite and leukocyte esterase, but moderate agreement for erythrocytes (κ = 0.51). Interpretation of clinically relevant (nitrite and/or leukocyte esterase positive) samples showed almost perfect agreement (κ = 0.88). Urinary dipsticks show similar test characteristics with urinary culture as gold standard, with sensitivities of 0.92 and 0.91 and specificities of 0.37 and 0.41 for visual and automated interpretation respectively.

Conclusion: Automated and visual dipstick analysis show near perfect agreement and perform similarly in predicting bacteriuria. However, automated analysis requires maintenance and occasionally measurement errors can occur.

期刊介绍: Scandinavian Journal of Primary Health Care is an international online open access journal publishing articles with relevance to general practice and primary health care. Focusing on the continuous professional development in family medicine the journal addresses clinical, epidemiological and humanistic topics in relation to the daily clinical practice. Scandinavian Journal of Primary Health Care is owned by the members of the National Colleges of General Practice in the five Nordic countries through the Nordic Federation of General Practice (NFGP). The journal includes original research on topics related to general practice and family medicine, and publishes both quantitative and qualitative original research, editorials, discussion and analysis papers and reviews to facilitate continuing professional development in family medicine. The journal''s topics range broadly and include: • Clinical family medicine • Epidemiological research • Qualitative research • Health services research.
