Temporal trends in antimicrobial prescribing during hospitalization for potential infection and sepsis.
This study examined whether the push to administer antimicrobials to prevent sepsis has increased antimicrobial use in general. This observational cohort study of hospitalized patients at 152 hospitals in 2 health care systems during 2013 to 2018 looked at almost 1.6 million patients (81% male), admitted via the emergency department with 2 or more systemic inflammatory response syndrome (SIRS) criteria. From 2013 to 2018 first antimicrobial administration to patients with sepsis decreased by 37 minutes. At the same time, antimicrobial use within 48 hours, days of antimicrobial therapy, and receipt of broad-spectrum coverage decreased among the broader cohort of patients with systemic inflammatory response syndrome (SIRS). This may have caused a decrease in in-hospital mortality, 30-day mortality, length of hospitalization, new MDR culture positivity, and new MDR blood culture positivity over the study period among both patients with sepsis and those with SIRS. For the overall hospital population there was no evidence that increasing antimicrobial timing for sepsis was associated with increasing antimicrobial use or impaired antimicrobial stewardship.

Antibiotic overuse and stewardship at hospital discharge: the reducing overuse of antibiotics at discharge home framework.
In this review, the authors discussed what is currently known about antibiotic overuse at hospital discharge, key barriers, and targets for improving antibiotic prescribing at discharge. They introduced an evidence-based framework, the Reducing Overuse of Antibiotics at Discharge Home Framework, for conducting discharge antibiotic stewardship.

Electronically available patient claims data improve models for comparing antibiotic use across hospitals: results from 576 U.S. facilities.
This study’s goal was to identify comorbidities causally related to appropriate antibiotic use and to compare seven models that include these comorbidities and other patient-level claims variables to a facility model for risk-adjusting inpatient antibiotic utilization. Subjects included adults discharged from Premier Database hospitals in 2016-2017. Findings showed that adding electronically available patient claims data to facility models consistently improved antibiotic utilization predictions and yielded substantial movement in hospitals' utilization rankings.

Effects of a collaborative, community hospital network for antimicrobial stewardship program implementation.
The authors investigated expertise, data resources, and educational tools to support antimicrobial stewardship programs (ASP) in hospitals. They found that network hospitals increased ASP activities and demonstrated decline in antimicrobial use over the 42-month study period. They concluded that their collaborative, consultative network proved a unique model in which hospitals can access ASP implementation expertise to support long-term program growth.

Significant regional differences in antibiotic use across 576 US hospitals
This study’s objective was to examine adult antibiotic use across 576 hospitals and nearly 12 million encounters in 2016-2017. Findings showed that adult inpatient antibiotic use remained high, driven predominantly by broad-spectrum agents. Recommendations included better understanding of the reasons for interhospital usage differences, including by region and teaching status, in order to inform efforts to reduce inappropriate antibiotic prescribing.

Association of a safety program for improving antibiotic use with antibiotic use and hospital-onset Clostridioides difficile infection rates among US hospitals.
Regulatory agencies and professional organizations recommend antibiotic stewardship programs (ASPs) in US hospitals. The optimal approach to establish robust, sustainable ASPs across diverse hospitals is unknown. The purpose of this study was to assess whether the Agency for Healthcare Research and Quality (AHRQ) Safety Program for Improving Antibiotic Use was associated with reductions in antibiotic use across US hospitals. The investigators concluded that AHRQ Safety Program appeared to enable diverse hospitals to establish ASPs and teach frontline clinicians to self-steward their antibiotic use.

Feasibility of core antimicrobial stewardship interventions in community hospitals.
The purpose of this study was to determine the feasibility and results of implementing 2 core stewardship intervention strategies in community hospitals. The two antimicrobial stewardship strategies targeted vancomycin hydrochloride, piperacillin-tazobactam, and the antipseudomonal carbapenems on formulary at the study hospitals: (1) modified preauthorization (PA), in which the prescriber had to receive pharmacist approval for continued use of the antibiotic after the first dose, and (2) postprescription audit and review (PPR), in which the pharmacist would engage the prescriber about antibiotic appropriateness after 72 hours of therapy.

Antimicrobial resistance prevalence, rates of hospitalization with septicemia and rates of mortality with sepsis in adults in different US states.
Researchers studied the relation between the prevalence of resistance to various antibiotics in different bacteria and rates of sepsis-related outcomes. They found that, among the different combinations of antibiotics/bacteria, prevalence of resistance to fluoroquinolones in E. coli had the strongest association with septicemia hospitalization rates for individuals aged over 50 years, and with sepsis mortality rates for individuals aged 18-84 years. They also found a number of positive correlations between prevalence of resistance for different combinations of antibiotics/bacteria and septicemia hospitalization/sepsis mortality rates in adults.

Indications and types of antibiotic agents used in 6 acute care hospitals, 2009-2010: a pragmatic retrospective observational study.
This study characterized the indications for antibiotic therapy, agents used, duration, combinations, and microbiological justification in 6 acute-care US facilities with varied location, size, and type of antimicrobial stewardship programs. It concluded that the use of broad-spectrum empirical therapy was prevalent in 6 US acute care facilities. Fluoroquinolones, vancomycin, and antipseudomonal penicillins were the most frequently used antibiotics, particularly for respiratory indications
