Accuracy of clean-catch technique for urine collection in young children

Abstract

Introduction: Urine collection in children should respect efficacy and child safety, considering child/family satisfaction and the quality of nursing care. Clean-Catch (CCU) has been described as a non-invasive, safe and quick urine collection method used in children lacking sphincter control, for Urinary Tract infections (UTI) diagnosis in alternative to invasive methods such as urethral catheterization/suprapubic aspiration (UC/SPA). Objective: To identify scientific evidence of the accuracy of clean-catch for the diagnosis of urinary infection in neonates. Methods: A systematic review was conducted based on Cochrane Handbook guidelines (Higgins & Green, 2011) of studies comparing urine contamination rates/ accuracy diagnosis between clean-catch and UC/SPA. Selected studies in PUBMED, EBSCO, Web of Science and Scielo databases, published between 2000 and 2017, according to previously established inclusion/exclusion criteria. Two researchers evaluated the studies’ quality. Results: In a total of 297 studies, two RCTs were included that met inclusion criteria. In the first study (Labrosse, Autmizguine & Gravel, 2016) it was verified that the contamination rates of the CCU group were 16% versus 6% for UC/SPA, whereas in the second study (Herreros et al., 2015) it was 5% versus 8% for CCU and UC respectively. Conclusions: The accuracy of clean-catch for nursing practice needs to be confirmed, given the small number of studies with methodological quality that use this technique.
