RESUMEN
OBJECTIVE: Urinary tract infections (UTIs) are the most commonly occurring infectious complication following kidney transplantation. Questions remain regarding whether asymptomatic bacteriuria (ASB) should be treated. The aim was to evaluate the incidence and management of ASB in kidney transplant recipients at a large academic medical center. METHODS: All subjects receiving an isolated kidney transplant between September 2012 and October 2016, and with at least one ASB episode were included. Demographics, symptomatology, and urine culture data were collected on subjects with bacteriuria in the first year post-transplant. Cultures were classified by symptoms, ASB treatment trends were analyzed, and ASB-to-UTI progression was compared between ASB treatment and non-treatment. RESULTS: A total of 527 subjects were transplanted with 64 developing at least one ASB episode. The incidence of ASB was 12.1% and treated 74.6% of the time. Neither lack of ASB treatment (P = 0.463) nor ASB within the first month post-transplant (P = 0.303) were associated with ASB-to-UTI progression. CONCLUSION: Despite high ASB treatment rate, this was not found to be protective against ASB-to-UTI progression. ASB within the first month post-transplant also did not correlate with increased progression risk. These results suggest minimization of ASB treatment in kidney transplant recipients remains an important antimicrobial stewardship target.

Background: Thiazide diuretics are often utilized to overcome loop diuretic resistance when treating acute decompensated heart failure (ADHF). In addition to a large cost advantage, several pharmacokinetic advantages exist when administering oral metolazone (MTZ) compared with intravenous (IV) chlorothiazide (CTZ), yet many providers are reluctant to utilize an oral formulation to treat ADHF. The purpose of this study was to compare the increase in 24-hour total urine output (UOP) after adding MTZ or CTZ to IV loop diuretics (LD) in patients with heart failure with reduced ejection fraction (HFrEF). Methods and Results: From September 2013 to August 2016, 1002 patients admitted for ADHF received either MTZ or CTZ in addition to LD. Patients were excluded for heart failure with preserved ejection fraction (HFpEF) (n = 469), <24-hour LD or UOP data prior to drug initiation (n = 129), or low dose MTZ/CTZ (n = 91). A total of 168 patients were included with 64% receiving CTZ. No significant difference was observed between the increase in 24-hour total UOP after MTZ or CTZ initiation (1458 [514, 2401] mL vs 1820 [890, 2750] mL, P = .251). Conclusions: Both MTZ and CTZ similarly increased UOP when utilized as an adjunct to IV LD. These results suggest that while thiazide agents can substantially increase UOP in ADHF patients with HFrEF, MTZ and CTZ have comparable effects.
RESUMEN
PURPOSE: To describe the Norton Healthcare electronic antimicrobial stewardship program (E-ASP), a novel prospective audit and feedback approach that leverages the electronic medical record to overcome efficiency barriers. Additionally, to describe an accompanying opt-out antimicrobial stewardship approach that addresses provider nonresponsiveness. SUMMARY: Prospective audit and feedback is recommended by antimicrobial stewardship guidelines; however, execution can be difficult due to labor requirements, delays in communication, and provider nonparticipation. The Norton E-ASP was developed to address these issues by reliably identifying target patients, documenting assessments, streamlining recommendation delivery, promoting handoff, and providing automated tracking of recommendation responses. Opt-out stewardship allows recommendations to be implemented if not rejected after 24 hours. CONCLUSION: A 25% reduction in target antimicrobial use has been achieved and sustained with the program. Use of the Norton E-ASP, including opt-out antimicrobial stewardship, broadened the reach and furthered the impact of infectious diseases pharmacists. Successes of this program justified addition of 3 full-time infectious diseases pharmacist positions at a large community health system. This strategy may serve as a model for tele-antimicrobial stewardship or other pharmacy recommendations.

Hospitalized coronavirus disease 2019 (COVID-19) patients receiving antibiotics (n = 173) were retrospectively assigned to the early or late discontinuation groups. The length of therapy was shorter in the early discontinuation group (3 vs 7 days; P < .0001). Mortality rates (14.3% vs 20.7%; P = .316) and length of stay (7 vs 9 days; P = .063) were similar.

In this study, we evaluated the impact of a microbiology nudge on de-escalation to first-generation cephalosporins in hospitalized patients with urinary tract infections secondary to Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis isolates with minimum inhibitory concentrations (MICs) ≤ 16 µg/mL. De-escalation to first generation-cephalosporins was uncommon at MICs = 4-16 µg/mL.
RESUMEN
Objective: To describe inpatient fluoroquinolone use and susceptibility data over a 10-year period after the implementation of an antimicrobial stewardship program (ASP) led by an infectious diseases pharmacist starting in 2011. Design: Retrospective surveillance study. Setting: Large community health system. Methods: Fluoroquinolone use was quantified by days of therapy (DOT) per 1,000 patient days (PD) and reported quarterly. Use data are reported for inpatients from 2016 to 2020. Levofloxacin susceptibility is reported for Pseudomonas aeruginosa and Escherichia coli for inpatients from 2011 to 2020 at a 4 adult-hospital health system. Results: Inpatient fluoroquinolone use decreased by 74% over a 5-year period, with an average decrease of 3.45 DOT per 1,000 PD per quarter (P < .001). Over a 10-year period, inpatient levofloxacin susceptibility increased by 57% for P. aeruginosa and by 15% for E. coli. P. aeruginosa susceptibility to levofloxacin increased by an average of 2.73% per year (P < .001) and had a strong negative correlation with fluoroquinolone use, r = -0.99 (P = .002). E. coli susceptibility to levofloxacin increased by an average of 1.33% per year (P < .001) and had a strong negative correlation with fluoroquinolone use, r = -0.95 (P = .015). Conclusions: A substantial decrease in fluoroquinolone use and increase in P. aeruginosa and E. coli levofloxacin susceptibility was observed after implementation of an antimicrobial stewardship program. These results demonstrate the value of stewardship services and highlight the effectiveness of an infectious diseases pharmacist led antimicrobial stewardship program.
RESUMEN
BACKGROUND: In September 2018, pharmacy antimicrobial stewardship (AMS) services were expanded to include weekends at this academic medical center. Activities performed by AMS pharmacists on the weekends include blood culture rapid diagnostic (RDT) review, antiretroviral therapy (ART) review, prospective audit and feedback (PAF) utilizing clinical decision support, vancomycin dosing, and operational support. The purpose of this study was to assess the operational and clinical impact of these expanded AMS services. METHODS: This single-center, quasi-experimental study included data from weekends before (9/2017-11/2017) and after (9/2018-11/2018) implementation. The descriptive primary outcome was the number of activities completed for each AMS activity type in the post-implementation group only. Secondary outcomes were time to AMS opportunity resolution, time to escalation or de-escalation following PAF or RDT alert, time to resolution of miscellaneous AMS related opportunities, length of stay (LOS), and antimicrobial use outcomes. RESULTS: During the post-implementation period 1258 activities were completed, averaging 97/weekend. Inclusion criteria for time to resolution outcomes were met by 72 patients pre-implementation and 59 patients post. The median (IQR) time to AMS opportunity resolution decreased from 18.5 hours pre-intervention (7.7-35.7) to 8.5 hours post-intervention (IQR 1.8-14.0), p < 0.01. Time to escalation was 11.6 hours compared to 1.7 hours (p = 0.1), de-escalation 16.7 hours compared to 10.8 hours (p = 0.03), and miscellaneous opportunity 40.8 hours compared to 13.2 hours (p = 0.01). No differences were observed in LOS or antimicrobial use outcomes. CONCLUSION: Presence of pharmacist-driven weekend AMS services significantly reduced time to resolution of AMS opportunities. These data support the value of weekend AMS services.
