"In long-term care facilities, treatment of asymptomatic bacteriuria (ASB) is common. However, randomized, controlled trials suggest that such treatment offers no benefit and may promote antimicrobial resistance," scientists writing in the American Journal of Infection Control report (see also Drug Resistance).
"For 3 months before and 30 months after instituting an educational intervention, we monitored the appropriateness of urine culture collection and antibiotic treatment based on published guidelines and examined the effect on total antimicrobial use. The intervention included education of nursing staff to discourage the collection of urine cultures in the absence of symptoms suggestive of urinary tract infection and of primary care practitioners to not treat ASB. In preintervention period, 23 of 38 (61%) antibiotic regimens prescribed for urinary tract indications were for ASK In the 6 months after the intervention, inappropriate submission of urine cultures decreased from 2.6 to 0.9 per 1000 patient-days (P
The researchers concluded: "Education of the nursing staff regarding appropriate criteria for requesting urine cultures should be a component of such interventions."
