RESUMO
The optimal management of bacteriuria/pyuria of clinically undetermined significance (BPCUS) is unknown. Among 220 emergency department patients prescribed antibiotics for BPCUS, we found frequent readmissions, which were mitigated by outpatient follow-up visits. Observation and follow-up for an unknown diagnosis should be emphasized over antibiotics due to high likelihood of readmissions.
RESUMO
Background: Urinary tract infections (UTIs) are over-diagnosed and over-treated in the emergency department (ED) leading to unnecessary antibiotic exposure and avoidable side effects. However, data describing effective large-scale antimicrobial stewardship program (ASP) interventions to improve UTI and asymptomatic bacteriuria (ASB) management in the ED are lacking. Methods: We implemented a multifaceted intervention across 23 community hospital EDs in Utah and Idaho consisting of in-person education for ED prescribers, updated electronic order sets, and implementation/dissemination of UTI guidelines for our healthcare system. We compared ED UTI antibiotic prescribing in 2021 (post-intervention) to baseline data from 2017 (pre-intervention). The primary outcomes were the percent of cystitis patients prescribed fluoroquinolones or prolonged antibiotic durations (>7 days). Secondary outcomes included the percent of patients treated for UTI who met ASB criteria, and 14-day UTI-related readmissions. Results: There was a significant decrease in prolonged treatment duration for cystitis (29% vs 12%, P < .01) and treatment of cystitis with a fluoroquinolone (32% vs 7%, P < .01). The percent of patients treated for UTI who met ASB criteria did not change following the intervention (28% pre-intervention versus 29% post-intervention, P = .97). A subgroup analysis indicated that ASB prescriptions were highly variable by facility (range 11%-53%) and provider (range 0%-71%) and were driven by a few high prescribers. Conclusions: The intervention was associated with improved antibiotic selection and duration for cystitis, but future interventions to improve urine testing and provide individualized prescriber feedback are likely needed to improve ASB prescribing practice.
RESUMO
Simultaneous administration of vancomycin and piperacillin-tazobactam (VPT) poses significant challenges related to physical and chemical compatibility, as well as clinical practice. A systematic review of available literature related to VPT Y-site compatibility was performed. Data was collected from primary and tertiary sources. Seven articles were included in addition to one internal assessment and one review article and information from tertiary drug databases. The literature supports the simultaneous administration via Y-site of piperacillin-tazobactam 33.75 mg/mL in normal saline (NS) and vancomycin 4 to 8 mg/mL in NS. The same drug products at differing concentrations, diluents, storage conditions, or preparations outside of this recommendation should be considered incompatible.
