In women with suspected urinary tract infection (UTI), a non-contaminated voided specimen is considered important for valid urinalysis and culture results. We assess whether midstream parted-labia catch (MSPC) instructions were provided by nurses, understood, and performed correctly, according to the patient.
We conducted a cross-sectional survey of English- and Spanish-speaking female patients submitting voided urine samples for urinalysis for suspected UTI. The survey was conducted in a public teaching hospital emergency department (ED) from June to December 2010, beginning 2 months after development and dissemination of a nursing MSPC instructions protocol. Research assistants administered the survey within 2 hours of urine collection. Nurses were unaware of the study purpose.
Of 129 patients approached, 74 (57%) consented and were included in the analysis. Median age was 35; 44% were Latino. Regarding instructions from nurses, patients reported the following: 45 (61%; 95% CI 50-72%) received any instructions; of whom 37 (82%; 95% CI 71-93%) understood them completely. Sixteen (36%; 95% CI 22-51%) were instructed to collect midstream; and 7 (16%; 95% CI 6-29%) to part the labia. Regardless of receiving or understanding instructions, 33 (45%; 95% CI 33-57%) reported actually collecting midstream, and 11 (15%, 95% CI 8-25%) parting the labia.
In this ED, instructions for MSPC urine collection frequently were not given, despite a nursing protocol, and patients rarely performed the essential steps. An evidence-based approach to urine testing in the ED that considers urine collection technique, is needed.
对于疑似尿路感染(UTI)的女性患者,采集未经污染的中段尿样进行尿液分析和培养是非常重要的。本研究旨在评估护士是否提供了中段尿留取(MSPC)指导,患者是否理解并正确执行。
本研究采用横断面调查方法,对 2010 年 6 月至 12 月期间在一家公立教学医院急诊科(ED)因疑似 UTI 而留取中段尿样进行尿液分析的英语和西班牙语女性患者进行调查。该研究在护士制定并发布 MSPC 指导方案 2 个月后开展。研究助理在留取尿液后 2 小时内进行问卷调查。护士不知道研究目的。
共对 129 名患者进行了调查,74 名(57%)患者同意并纳入分析。患者的中位年龄为 35 岁,44%为拉丁裔。关于护士的指导,患者报告如下:45 名(61%;95%CI 50-72%)患者接受了任何指导;其中 37 名(82%;95%CI 71-93%)完全理解。16 名(36%;95%CI 22-51%)患者被指导留取中段尿,7 名(16%;95%CI 6-29%)患者被指导分开阴唇。无论是否接受或理解指导,33 名(45%;95%CI 33-57%)患者实际留取了中段尿,11 名(15%;95%CI 8-25%)患者分开了阴唇。
在本 ED,尽管有护理方案,但 MSPC 尿液采集指导经常未被提供,患者很少执行关键步骤。需要一种基于证据的 ED 尿液检测方法,考虑尿液采集技术。
