Identifying high-risk subphenotypes and associated harms from delayed antibiotic orders and delivery.
Delayed antibiotic use can cause harms including mortality in certain novel patient subphenotypes. This study’s objective was to characterize and compare patients who experienced order or delivery delays and identify those novel subphenotypes with elevated risk of harm from delays. Two tertiary care medical centers and four community-based hospitals were analyzed retrospectively from 2008 to 2017. Patient demographics, vitals, laboratory values, medical order and administration times, and in-hospital survival data were obtained from their electronic health records. Order and delivery delays for each admission was calculated. Causal forests, a machine learning method, was used to identify the high-risk subgroup. Out of 60,817 admissions included, delays occurred in 58% of patients. Each additional hour of order delay and delivery delay was associated with increased mortality. A patient subgroup was identified with higher comorbidity burden, greater organ dysfunction, and abnormal initial lactate measures that had a higher risk of death associated with delays.

Risk of antibiotic treatment failure in premenopausal women with uncomplicated urinary tract infection.
This study compared treatment outcomes for various antibiotics in premenopausal women with uncomplicated urinary tract infections (UTIs). The authors compared treatment with fluoroquinolones (first-line), trimethoprim-sulfamethoxazole (TMP/SMX) (first-line), nitrofurantoin (first-line), narrow-spectrum β-lactams (non-first-line), and amoxicillin/ampicillin (non-recommended). Over 1.1 million patient outcomes were analyzed. The risk of treatment failure differed by the antibiotic type, with higher risk associated with TMP/SMX versus nitrofurantoin, and lower or similar risk associated with broad- versus narrow-spectrum β-lactams.

Non-visit-based and non-infection-related antibiotic use in the US: a cohort study of privately insured patients during 2016-2018.
Ambulatory antibiotic prescriptions without a clinic visit or without documentation of infection could represent overuse and contribute to adverse outcomes. We aim to describe US ambulatory antibiotic prescribing, including those without an associated visit or infection diagnosis. The investigators conducted an observational cohort study using data of all patients receiving antibacterial, antibiotic prescriptions from 04/01/2016 to 06/30/2018 in a large US private health insurance plan. They concluded that over half of ambulatory antibiotic use was either non-visit-based or non-infection-related.

Prevalence of inappropriate antibiotic prescribing by antibiotic among privately and publicly insured non-elderly US patients, 2018.
The authors used 2018 commercial and Medicaid claims to assess inappropriate prescribing of antibiotics. In their analysis, 22% of antibiotic claims were inappropriate. Azithromycin had an outsized role in inappropriate prescribing. They concluded that broad-based stewardship initiatives remain important given widespread inappropriate prescribing of all antibiotics.

Management of trichomoniasis in the setting of 5-nitroimidazole hypersensitivity.
Metronidazole and other 5-nitroimidazoles are the mainstay of Trichomonas vaginalis treatment, with few efficacious and safe treatment options available outside of this class. Patients with trichomoniasis and a history of a clinically confirmed hypersensitivity reaction to 5-nitroimidazoles present a management challenge for clinicians. In this study, the investigators examine management of Trichomoniasis in the setting of 5-nitroimidazole hypersensitivity.

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.

Implementation of an antibiotic stewardship intervention to reduce prescription of fluoroquinolones: a human factors analysis in two intensive care units.
In this study, researchers conducted an in-depth analysis of an intervention aimed at limiting ICU prescriber access to fluoroquinolones (FQ) in the ICUs of two hospitals. Their results showed some differences in the implementation of the FQ intervention between the two studied ICUs, such as level and method of FQ restriction, and training and communication with physicians and pharmacists. In both ICUs, several organizational learning mechanisms helped quickly to identify problems with the intervention and to ensure that changes were made in a just-in-time manner. Despite their organizational differences, both sites developed strategies to implement the FQ intervention successfully.

Respiratory viral testing and antibacterial treatment in patients hospitalized with community-acquired pneumonia.
Researchers studied the frequency of respiratory viral testing and its associations with antimicrobial utilization in adult patients hospitalized with community-acquired pneumonia. They found that, of patients with pneumonia on admission, 24.5% were tested for respiratory viruses, 94.8% were tested for influenza, and 20.7% were tested for other viruses. They concluded that a minority of patients hospitalized with pneumonia were tested for respiratory viruses; only a fraction of potential viral pathogens were assayed; and patients with positive viral tests often received long antibacterial courses.

Decreasing ICU-associated Clostridioides difficile infection through fluoroquinolone restriction, the FIRST trial: a study protocol.
Clostridioides difficile infection (CDI) is one of the most common healthcare-associated infections in the USA, having high incidence in intensive care units (ICU). Antibiotic use increases risk of CDI, with fluoroquinolones (FQs) particularly implicated. In healthcare settings, antibiotic stewardship (AS) and infection control interventions are effective in CDI control, but there is little evidence regarding the most effective AS interventions. In this paper the investigators describe their multisite, stepped-wedge, cluster, effectiveness-implementation clinical trial.

Empiric antibacterial therapy and community-onset bacterial coinfection in patients hospitalized with COVID-19: a multi-hospital cohort study.
A randomly sampled cohort of 1705 patients hospitalized with COVID-19 was used. Data was collected on early empiric antibacterial therapy within 2 days of hospitalization, empiric antibacterial therapy and community-onset bacterial co-infections. Of the 1705 patients, 56.6% were prescribed early empiric antibacterial therapy, with 3.5% having a confirmed community-onset bacterial infection. Use varied across hospitals, ranging from 27% to 84%. Patients were more likely to receive the therapy if they were older, had more severe illness, had a lobar infiltrate, or were admitted to a for-profit hospital. Over the one-month period empiric antibacterial use decreased.

Characteristics associated with opioid and antibiotic prescribing by dentists.
The objective of this study was to identify county-level characteristics that may be high-impact targets for opioid and antibiotic interventions to improve dental prescribing. The investigators concluded that dental prescribing of opioids was decreasing, whereas dental antibiotic prescribing was increasing. High prescribing of antibiotics was associated with high prescribing of opioids. The investigators suggested that strategies focused on optimizing dental antibiotics and opioids are needed given their impact on population health.

De-escalation of empiric antibiotics following negative cultures in hospitalized patients with pneumonia: rates and outcomes.
This study assessed antibiotic de-escalation practices across hospitals and their associations with outcomes in hospitalized patients diagnosed with pneumonia with negative cultures. The authors included 14,170 adults admitted with pneumonia in 2010-2015 to 164 US hospitals if they had negative blood and/or respiratory cultures and received both anti-MRSA and antipseudomonal agents other than quinolones. If empiric drugs were stopped on day 4 while continuing another antibiotic it was defined at de-escalation. Patients were propensity adjusted for de-escalation and compared on in-hospital 14-day mortality, late deterioration with ICU transfer, length-of-stay (LOS) and costs. Thirteen percent (1924 patients) had both initial empiric drugs stopped by hospital day 4. De-escalation rates at hospitals ranged from 2-35% and the established rate quartiles were not significantly associated with outcomes. Even at hospitals in the top quartile of de-escalation, the de-escalation rates were lower than 50%.

"I never get better without an antibiotic": antibiotic appeals and how to respond.
In this paper, the investigators present various scenarios in which patients who do not meet guideline criteria for antibiotic prescribing, appeal to clinicians for antibiotics. The authors discuss the issue of antiobiotic appeals and provide examples of responses for clinicians. They suggest that clinicians should acquire a stock of responses to these appeals grounded in the latest evidence about antibiotics.

Antibiotic regimens and associated outcomes in children hospitalized with staphylococcal scalded skin syndrome.
Controversy exists regarding the optimal antibiotic regimen for use in hospitalized children with staphylococcal scalded skin syndrome (SSSS). Various regimens may confer toxin suppression and/or additional coverage for methicillin-susceptible Staphylococcus aureus (MSSA) or methicillin-resistant S aureus (MRSA). The purpose of this study was to describe antibiotic regimens in hospitalized children with SSSS and examine the association between antistaphylococcal antibiotic regimens and patient outcomes.

The impact of beta-lactam allergy labels on hospitalized children.
Investigators sought to determine the impact of beta-lactam allergy labels in hospitalized children with regards to clinical and economic outcomes. Subjects were pediatric patients hospitalized at Intermountain Healthcare facilities from 2007 to 2017 who received one or more 1 dose of an antibiotic during their admission. The researchers found that patients with beta-lactam allergy received broader-spectrum antibiotics and experienced higher antibiotic costs than nonallergic controls. However, there were no differences in the length of stay, readmission rates, or total number of days of antibiotics between allergic and nonallergic patients.

Antibiotic susceptibility of Escherichia coli among infants admitted to neonatal intensive care units across the US From 2009 to 2017.
Investigators assessed the epidemiologic characteristics and antibiotic susceptibility patterns of E coli in infants admitted to neonatal intensive care units in the US over time. Using the Premier Health Database, they found nonsusceptibility to commonly administered antibiotics in substantial proportions of neonatal E coli isolates, with no significant change from 2009 to 2017. They suggested that their findings may inform empirical antibiotic choices for newborn infants.

Criteria for intradermal skin testing and oral challenge in patients labeled as fluoroquinolone allergic.
This cohort study at Vanderbilt University looked at the utility of intradermal skin testing and oral challenge in patients labeled as fluoroquinolone (FQ) allergic. The authors concluded that most patients with non-anaphylactic immediate histories such as urticaria will tolerate single-dose 200- to 250-mg challenge with an FQ and further tolerate therapeutic courses of FQ. For patients with a history of anaphylaxis FQ, skin test positivity is needed using a distinct set of criteria.

Dose, timing, and spectrum of prenatal antibiotic exposure and risk of childhood asthma.
The potential for prenatal antibiotic exposure to influence asthma risk is not clear. The investigators aimed to determine the effect of timing, dose, and spectrum of prenatal antibiotic exposure on the risk of childhood asthma. The investigators concluded that increased cumulative dose, early pregnancy first course, and broad-spectrum antibiotic exposure were associated with childhood asthma risk.

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.

Vancomycin hypersensitivity reactions documented in electronic health records.
This study’s objective is to describe vancomycin hypersensitivity reaction (HSR) epidemiology in hospitals documented in electronic health records. Vancomycin is the most commonly prescribed antimicrobial in US hospitals. A cross-sectional study of patients with 1 or more encounter from 2017 to 2019 and an electronic health record vancomycin drug allergy label (DAL) in 2 US health care systems was conducted. Prevalence and trends of vancomycin DALs and assessed active DALs by HSR phenotype was determined. Out of almost 4.5 million patients, 14,426 (0.3%) had a vancomycin DAL with 18,761 documented reactions. Out of those 18,761 vancomycin HSRs, 42.1% were immediate phenotypes and 20.7% were delayed phenotypes. Common reactions were rash and red man syndrome (RMS). Anaphylaxis occurred in 6% of HSRs. RMS reaction was more likely for males and less likely for Blacks.
