To Clean or Not to Clean: Effect on Contamination Rates in Midstream Urine Collections in Toilet-Trained Children

摘要: OBJECTIVE. Urinary tract infection is one of the most common bacterial infections among children. Difficulty in specimen collection and interpretation inadequately collected specimens may contribute to misdiagnosis urinary infection. Our objective was assess effect perineal/genital cleaning on contamination rates midstream urine collections toilet-trained METHODS. We conducted a randomized trial children who presented tertiary care pediatric emergency department between November 1, 2004, October 2005. All were ages 2 18 years had sample requested eligible. Those whose parents consented cluster-randomized by week either or not perineum with soap. The risk for contaminated culture (defined as growth RESULTS. A total 350 enrolled. rate group 14 (7.8%) 179 vs 41 (23.9%) 171 noncleaning group. Children randomly assigned less likely have positive urinalysis (37 [20.6%]) than those (63 [36.8%]). CONCLUSIONS. Urine are higher that from when obtained without cleaning. Cleaning reduce returning repeat cultures receiving unnecessary antibiotic treatment investigations.
