Antibiotic indications and appropriateness in the pediatric intensive care unit: a 10-center point prevalence study.
The purpose of this study was to describe indications and appropriateness of antibiotic orders in pediatric intensive care unit (PICU) patients. The study found that of 1462 patients admitted to participating PICUs, 58% had at least 1 antibiotic order, with 1277 antibiotic orders being reviewed. Common indications were empiric therapy for suspected bacterial infections without sepsis or septic shock, nonoperative prophylaxis, empiric therapy for sepsis or septic shock, community-acquired pneumonia, and post-operative prophylaxis. Appropriateness was evaluated for 985 orders for which an evidence-based heading for appropriateness could be created. Of these, 34% were categorized as inappropriate. Indications with the most orders classified as inappropriate were empiric therapy for suspected bacterial infection without sepsis or septic shock, sepsis or septic shock, CAP, ventilator-associated infections, and post-operative prophylaxis. The proportion of antibiotics classified as inappropriate differed across institutions.

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.

Association of diagnostic stewardship for blood cultures in critically ill children with culture rates, antibiotic use, and patient outcomes: results of the Bright STAR Collaborative.
The purpose of this AHRQ-funded prospective study was to assess the relationship between a 14-site PICU blood culture collaborative, the Bright STAR (Testing Stewardship for Antibiotic Reduction) collaborative, and culture rates, antibiotic use, and patient outcomes. The researchers collected data from each participating PICU across the United States and from the Children’s Hospital Association Pediatric Health Information System. The main outcome was blood culture rates, with secondary outcomes including: broad-spectrum antibiotic use and PICU rates of central line-associated bloodstream infection (CLABSI), Clostridioides difficile infection, readmission, length of stay, sepsis, severe sepsis/septic shock, and mortality. The study found that the blood culture rate preimplementation across the 14 PICUs was 149.4 per 1000 patient days per month, and the rate postimplementation was 100.5 for a 33% relative reduction postimplementation. For those same periods, the rate of antibiotic use decreased from 506 days per 1000 patient-days per month preimplementation to 440 days per 1000 patient-days per month postimplementation, which reflects a 13% relative reduction. Rates of CLABSI decreased from 1.8 to 1.1 per 1000 central venous line days per month, a 36% relative reduction. The variables of length of stay, readmission, sepsis, severe sepsis/septic shock, and mortality were similar before and after implementation. The researchers concluded that collaborative interventions can reduce blood culture and antibiotic use in the PICU.

Inappropriate empirical antibiotic therapy for bloodstream infections based on discordant in-vitro susceptibilities: a retrospective cohort analysis of prevalence, predictors, and mortality risk in US hospitals.
Researchers sought to establish the population-level burden, predictors, and mortality risk of in-vitro susceptibility-discordant empirical antibiotic therapy among patients with bloodstream infections. They found that approximately one in five patients with bloodstream infections in US hospitals received discordant empirical antibiotic therapy, receipt of which was closely associated with infection with antibiotic-resistant pathogens. Receiving discordant empirical antibiotic therapy was associated with increased odds of mortality overall, even in patients without sepsis. They concluded that early identification of bloodstream pathogens and resistance will probably improve population-level outcomes.

Recalibrating our approach to the management of sepsis: how the four moments of antibiotic decision-making can help.
In this paper, the authors describe The Four Moments of Antibiotic Decision Making. The Four Moments were conceived as part of the Agency for Healthcare Research and Quality (AHRQ) Safety Program for Improving Antibiotic Use. The Four Moments provide a pragmatic approach to the core principle of antibiotic stewardship – ensuring patients who require antibiotic therapy promptly receive regimens associated with clinical success, while protecting patients from potential harm associated with unnecessary exposure to antibiotics.

Levels of outpatient prescribing for four major antibiotic classes and rates of septicemia hospitalization in adults in different US states - a statistical analysis.
The authors related state-specific rates of outpatient prescribing overall for oral fluoroquinolones, penicillins, macrolides, and cephalosporins between 2011 and 2012 to state-specific rates of septicemia hospitalization in several age groups of adults. They found positive associations between the rates of prescribing for penicillins and the rates of hospitalization with septicemia in US adults aged 50-84 years and recommended further studies.

A critical analysis of the literature on time-to-antibiotics in suspected sepsis.
The Surviving Sepsis Campaign recommends immediate antibiotics for all patients with suspected sepsis and septic shock, ideally within 1 hour of recognition. An accurate understanding of the precise relationship between time-to-antibiotics and mortality for patients with possible sepsis is therefore critical. In this study, the investigators elaborate on potential sources of bias and try to distill a better understanding of what the true relationship between time-to-antibiotics and mortality may be for patients with suspected sepsis or septic shock.

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.
