Evaluation of Antibiotic Use for Dental-Related Infections in Dental Clinics Associated With an Academic Safety Net Institution.

This retrospective study found lower antibiotic prescribing rates by outpatient dentists than previous literature, but with deviations from guideline recommendations in antibiotic indications and durations of treatment for oral pain and swelling. These findings will guide future stewardship interventions to promote guideline-directed therapy plans.

Extended-Infusion β-Lactam Therapy, Mortality, and Subsequent Antibiotic Resistance Among Hospitalized Adults With Gram-Negative Bloodstream Infections.

Importance: Current evidence is conflicting for associations of extended-infusion β-lactam (EI-BL) therapy with clinical outcomes.

Objective: To investigate the association of EI-BL therapy with survival, adverse events, and emergence of antibiotic resistance in adults with gram-negative bloodstream infections (GN-BSI).

Design, Setting, And Participants: This cohort study of consecutive adults with GN-BSI admitted to 24 United States hospitals between January 1, 2019, and December 31, 2019, receiving EI-BL were compared with adults with GN-BSI receiving the same agents as intermittent infusion β-lactam (II-BL; ≤1-hour infusions).

Transition to Oral Antibiotic Therapy for Hospitalized Adults With Gram-Negative Bloodstream Infections.

Importance: Management of gram-negative bloodstream infections (GN-BSIs) with oral antibiotics is highly variable.

Objective: To examine the transition from intravenous (IV) to oral antibiotics, including selection, timing, and associated clinical and microbial characteristics, among hospitalized patients with GN-BSIs.

Design, Setting, And Participants: A retrospective cohort study was conducted of 4581 hospitalized adults with GN-BSIs at 24 US hospitals between January 1 and December 31, 2019.

Multiple-Dose Dalbavancin Regimens as the Predominant Treatment of Deep-Seated or Endovascular Infections: A Scoping Review.

Off-label use of dalbavancin for deep-seated and endovascular infections has been increasing. We performed a scoping review to evaluate the evidence for use of multiple-dose dalbavancin regimens as the predominant therapy for these indications. Predominant therapy was defined as use of dalbavancin without other concurrent antibiotics for more than half of the total treatment duration.

Factors Associated With Longer Than Recommended Durations of Antibiotic Therapy for Uncomplicated Ambulatory Infections in an Integrated Healthcare System.

Across the ambulatory care network of an integrated health care system, durations of antibiotic therapy prescribed for uncomplicated infections were longer than recommended in 39% of cases. By logistic regression, site of care, prescriber characteristics, and type of infection were independently associated with longer than recommended durations of therapy.

Use of a Standardized Dalbavancin Approach to Facilitate Earlier Hospital Discharge for Vulnerable Patients Receiving Prolonged Inpatient Antibiotic Therapy.

Twenty-seven patients receiving prolonged inpatient antibiotic therapy for a serious bacterial infection received a single dose of dalbavancin 7-10 days before the planned end date to facilitate earlier hospital discharge. Eighty-one percent met criteria for clinical success, 7% experienced a potential adverse event, and 182 hospital days were averted.

Antibiotic Prescribing Patterns for Acute Otitis Media for Children 2 Years and Older.

Objective: To determine the frequency that non-first-line antibiotics, safety-net antibiotic prescriptions (SNAPS), and longer than recommended durations of antibiotics were prescribed for children ≥2 years of age with acute otitis media and examine patient and system level factors that contributed to these outcomes.

Study Design: Children age ≥2 years with acute otitis media seen at Denver Health Medical Center outpatient locations from January to December 2018 were included. The percentages of patients who received first-line antibiotics, SNAPs, and recommended durations of antibiotics were determined.

Effectiveness of Shorter Versus Longer Durations of Therapy for Common Inpatient Infections Associated With Bacteremia: A Multicenter, Propensity-Weighted Cohort Study.

Background: National guidelines for pneumonia (PNA), urinary tract infection (UTI), and acute bacterial skin and skin structure infection (ABSSSI) do not address treatment duration for infections associated with bacteremia. We evaluated clinical outcomes of patients receiving shorter (5-9 days) versus longer (10-15 days) duration of antibiotics.

Methods: This was a multicenter retrospective cohort study of inpatients with uncomplicated PNA, UTI, or ABSSSI and associated bacteremia.

Patterns of use and perceptions of an institution-specific antibiotic stewardship application among emergency department and urgent care clinicians.

We surveyed emergency department and urgent care clinicians to assess patterns of use and perceived usefulness of a local antibiotic stewardship application to deliver institution-specific prescribing guidance. Among 114 eligible respondents, the application was widely utilized, and it was perceived to be a useful clinical resource that improved prescribing.

Corticosteroids for Posttransplant Immune Reconstitution Syndrome in Meningoencephalitis: Case Report and Literature Review.

represents an emerging fungal pathogen of immunocompromised and immunocompetent hosts in the United States. To our knowledge, this is the first case of posttransplant immune reconstitution syndrome due to meningoencephalitis successfully treated with corticosteroids. We also report successful maintenance phase treatment with isavuconazole, a novel triazole, following fluconazole-induced prolonged QT syndrome.

A Novel Approach to Evaluate Antibiotic Utilization Across the Spectrum of Inpatient and Ambulatory Care and Implications for Prioritization of Antibiotic Stewardship Efforts.

Background: Antibiotic overuse remains a significant problem. The objective of this study was to develop a methodology to evaluate antibiotic use across inpatient and ambulatory care sites in an integrated healthcare system to prioritize antibiotic stewardship efforts.

Methods: We conducted an epidemiologic study of antibiotic use across an integrated healthcare system on 12 randomly selected days from 2017 to 2018.

Omadacycline: A New Tetracycline Antibiotic.

Objective: To review the chemistry, pharmacology, microbiology, pharmacokinetics, pharmacodynamics, clinical efficacy, tolerability, dosage, and administration of omadacycline, a new tetracycline antibiotic.

Data Sources: A literature search through PubMed, Google Scholar, and clinicaltrials.gov was conducted (2008 to October 2018) using the search terms omadacycline and PTK-0796.

Implementation of an institution-specific antimicrobial stewardship smartphone application.

Smartphones are increasingly used to access clinical decision support, and many medical applications provide antimicrobial prescribing guidance. However, these applications do not account for local antibiotic resistance patterns and formularies. We implemented an institution-specific antimicrobial stewardship smartphone application and studied patterns of use over a 1-year period.

Appropriateness of antibiotic prescriptions for acute sinusitis and pharyngitis in an integrated healthcare system.

We evaluated the appropriateness of antibiotic prescriptions for acute sinusitis and pharyngitis. Overall, 81% of antibiotic prescriptions for acute sinusitis were inappropriate and 48% of antibiotic prescriptions for pharyngitis were inappropriate. Types of prescribing errors differed between the 2 infections, including lack of an indication for antibiotics and excessive duration in ~50% of sinusitis cases and incorrect antibiotic dose in ~33% of pharyngitis cases.

A Statewide Antibiotic Stewardship Collaborative to Improve the Diagnosis and Treatment of Urinary Tract and Skin and Soft Tissue Infections.

Background: Colorado hospitals participated in a statewide collaborative to improve the management of inpatient urinary tract infections (UTIs) and skin and soft tissue infections (SSTIs). We evaluated the effects of the intervention on diagnostic accuracy and antibiotic use.

Methods: The main collaborative outcomes were proportion of UTI diagnoses that met criteria for symptomatic UTI; exposure to fluoroquinolones (UTI only); duration of therapy (UTIs and SSTIs); and exposure to antibiotics with broad gram-negative activity (SSTIs only).
