Abstract
Children, caregivers, and clinicians often prefer midstream clean catch technique to urethral catheterization for obtaining urine cultures. However, contamination is common, potentially resulting in unnecessary medical intervention and cost. With this resident-led initiative, we aimed to reduce pediatric midstream clean catch urine culture contamination over 6 months.
A bundled intervention was implemented in the emergency department, inpatient units, and outpatient clinics at our institution. Baseline contamination rates were collected April 2016 to September 2017; the intervention was introduced October 2017 to March 2018 and evaluated April 2018 to September 2018. Sustainability was measured October 2018 to September 2020. Balancing measures included rates of repeat urine cultures, positive cultures, and contaminated cultures by urethral catheterization.
Rates of midstream clean catch urine culture contamination were 45.3% preintervention and 30.9% postintervention, a 14.7% (95% confidence interval: 8.0% to 21.5%) absolute decrease. Before and after intervention, girls and patients 16 to 17 years old had the highest rates of midstream clean catch contamination. Six months postintervention, the rate of repeat urine culture decreased from 4.9% to 0.9% with no change in positive culture results or contaminated cultures by urethral catheterization. Over the subsequent 2 years, the impact of the intervention decreased (rate of contamination over 30 months postintervention: 38.4%, a 7.3% [95% confidence interval: 2.9% to 11.6%] absolute decrease; rate of repeat urine culture: 3.2%).
An intervention to improve midstream clean catch urine culture collection was associated with a clinically meaningful decrease in contamination. Impact of the resident-led intervention decreased over time.
