The clinical impact of a urinary tract infection management bundle in a tertiary-care teaching hospital

ObjectiveThe aim of this study was to assess the impact of a urinary tract infection (UTI) management bundle to reduce the treatment of asymptomatic bacteriuria (AB) and to improve the management of symptomatic UTIs.DesignBefore-and-after intervention study.SettingsTertiary-care hospital.PatientsConsecutive sample of inpatients with positive single or mixed-predominant urine cultures collected and reported while admitted to the hospital.MethodsThe UTI management bundle consisted of nursing and prescriber education, modification of the reporting of positive urine cultures, and pharmacists' prospective audit and feedback. A retrospective chart review of consecutive inpatients with positive urinary cultures was performed before and after implementation of the management bundle.ResultsPrior to the implementation of the management bundle, 276 patients were eligible criteria for chart review. Of these 276 patients, 165 (598%) were found to have AB; of these 165 patients with AB, 111 (673%) were treated with antimicrobials. Moreover, 268 patients met eligibility criteria for postintervention review. Of these 268, 133 patients (496%) were found to have AB; of these 133 with AB, 22 (165%) were treated with antimicrobials. Thus, a 755% reduction of AB treatment was achieved. Educational components of the bundle resulted in a substantial decrease in nonphysician-directed urine sample submission. Adherence to a UTI management algorithm improved substantially in the intervention period, with a notable decrease in fluoroquinolone prescription for empiric UTI treatment.ConclusionsA UTI management bundle resulted in a dramatic improvement in the management of urinary tract infection, particularly a reduction in the treatment of AB and improved management of symptomatic UTI.
