Impact of clinician feedback reports on antibiotic use in children hospitalized with community-acquired pneumonia.

Background: Feedback reports summarizing clinician performance are effective tools for improving antibiotic use in the ambulatory setting, but the effectiveness of feedback reports in the hospital setting is unknown.

Methods: Quasi-experimental study conducted between December 2021 and November 2023 within a pediatric health system measuring the impact of clinician feedback reports delivered by email and reviewed in a monthly meeting on appropriate antibiotic use in children hospitalized with community-acquired pneumonia (CAP). We used an interrupted time series analysis (ITSA) to estimate the immediate change and change over time in the proportion of CAP encounters adherent to validated metrics of antibiotic choice and duration, then used Poisson regression to estimate intervention effect as a rate ratio (RR).

Stewardship Prompts to Improve Antibiotic Selection for Pneumonia: The INSPIRE Randomized Clinical Trial.

Importance: Pneumonia is the most common infection requiring hospitalization and is a major reason for overuse of extended-spectrum antibiotics. Despite low risk of multidrug-resistant organism (MDRO) infection, clinical uncertainty often drives initial antibiotic selection. Strategies to limit empiric antibiotic overuse for patients with pneumonia are needed.

Stewardship Prompts to Improve Antibiotic Selection for Urinary Tract Infection: The INSPIRE Randomized Clinical Trial.

Importance: Urinary tract infection (UTI) is the second most common infection leading to hospitalization and is often associated with gram-negative multidrug-resistant organisms (MDROs). Clinicians overuse extended-spectrum antibiotics although most patients are at low risk for MDRO infection. Safe strategies to limit overuse of empiric antibiotics are needed.

Length of antibiotic therapy among adults hospitalized with uncomplicated community-acquired pneumonia, 2013-2020.

Objective: The 2014 US National Strategy for Combating Antibiotic-Resistant Bacteria (CARB) aimed to reduce inappropriate inpatient antibiotic use by 20% for monitored conditions, such as community-acquired pneumonia (CAP), by 2020. We evaluated annual trends in length of therapy (LOT) in adults hospitalized with uncomplicated CAP from 2013 through 2020.

Methods: We conducted a retrospective cohort study among adults with a primary diagnosis of bacterial or unspecified pneumonia using codes in MarketScan and the Centers for Medicare & Medicaid Services databases.

An Update From the National Healthcare Safety Network on Hospital Antibiotic Stewardship Programs in the United States, 2014-2021.

Background: In 2014, the Centers for Disease Control and Prevention (CDC) released the Core Elements of Hospital Antibiotic Stewardship Programs (ASPs) and began monitoring uptake through the National Healthcare Safety Network (NHSN) Annual Hospital Survey. In 2019, CDC updated the Core Elements and in 2022 released the Priorities for Hospital Core Element Implementation. We describe Core Element uptake from 2014 to 2021, provide a snapshot of specific ASP practices in acute care hospitals in 2021, and describe how we plan to monitor stewardship moving forward.

Antibiotic Use Among Hospitalized Patients With COVID-19 in the United States, March 2020-June 2022.

We conducted a retrospective study to describe antibiotic use among US adults hospitalized with a COVID-19 diagnosis. Despite a decrease in overall antibiotic use, most patients hospitalized with COVID-19 received antibiotics on admission (88.1%) regardless of critical care status, highlighting that more efforts are needed to optimize antibiotic therapy.

Defining access without excess: expanding appropriate use of antibiotics targeting multidrug-resistant organisms.

Antimicrobial resistance remains a significant global public health threat. Although development of novel antibiotics can be challenging, several new antibiotics with improved activity against multidrug-resistant Gram-negative organisms have recently been commercialised. Expanding access to these antibiotics is a global public health priority that should be coupled with improving access to quality diagnostics, health care with adequately trained professionals, and functional antimicrobial stewardship programmes.

Health Equity and Antibiotic Prescribing in the United States: A Systematic Scoping Review.

We performed a scoping review of articles published from 1 January 2000 to 4 January 2022 to characterize inequities in antibiotic prescribing and use across healthcare settings in the United States to inform antibiotic stewardship interventions and research. We included 34 observational studies, 21 cross-sectional survey studies, 4 intervention studies, and 2 systematic reviews. Most studies (55 of 61 [90%]) described the outpatient setting, 3 articles were from dentistry, 2 were from long-term care, and 1 was from acute care.

Pharmacist-Driven Transitions of Care Practice Model for Prescribing Oral Antimicrobials at Hospital Discharge.

Importance: Although prescribers face numerous patient-centered challenges during transitions of care (TOC) at hospital discharge, prolonged duration of antimicrobial therapy for common infections remains problematic, and resources are needed for antimicrobial stewardship throughout this period.

Objective: To evaluate a pharmacist-driven intervention designed to improve selection and duration of oral antimicrobial therapy prescribed at hospital discharge for common infections.

Design, Setting, And Participants: This quality improvement study used a nonrandomized stepped-wedge design with 3 study phases from September 1, 2018, to August 31, 2019.

National Healthcare Safety Network 2018 Baseline Neonatal Standardized Antimicrobial Administration Ratios.

Background: The microbiologic etiologies, clinical manifestations, and antimicrobial treatment of neonatal infections differ substantially from infections in adult and pediatric patient populations. In 2019, the Centers for Disease Control and Prevention developed neonatal-specific (Standardized Antimicrobial Administration Ratios SAARs), a set of risk-adjusted antimicrobial use metrics that hospitals participating in the National Healthcare Safety Network's (NHSN's) antimicrobial use surveillance can use in their antibiotic stewardship programs (ASPs).

Methods: The Centers for Disease Control and Prevention, in collaboration with the Vermont Oxford Network, identified eligible patient care locations, defined SAAR agent categories, and implemented neonatal-specific NHSN Annual Hospital Survey questions to gather hospital-level data necessary for risk adjustment.

Trends in Antibiotic Use in United States Hospitals During the Coronavirus Disease 2019 Pandemic.

Assessment of the Appropriateness of Antimicrobial Use in US Hospitals.

Importance: Hospital antimicrobial consumption data are widely available; however, large-scale assessments of the quality of antimicrobial use in US hospitals are limited.

Objective: To evaluate the appropriateness of antimicrobial use for hospitalized patients treated for community-acquired pneumonia (CAP) or urinary tract infection (UTI) present at admission or for patients who had received fluoroquinolone or intravenous vancomycin treatment.

Design, Setting, And Participants: This cross-sectional study included data from a prevalence survey of hospitalized patients in 10 Emerging Infections Program sites.

A Pilot Study to Evaluate the Impact of a Nurse-Driven Urine Culture Diagnostic Stewardship Intervention on Urine Cultures in the Acute Care Setting.

Background: The role of nurses in diagnostic stewardship in hospitals remains largely unknown.

Methods: In this before-after study, researchers assessed the impact of a nurse-driven urine culture (UrCx) stewardship intervention for adults with and without urinary catheters on a general medicine unit of a large hospital. The intervention included education on principles of diagnostic stewardship, identification of a nurse champion to serve as liaison between nursing and the antibiotic stewardship program, and implementation of an algorithm to guide discussions with hospitalists about situations when UrCx may not be needed.

National Healthcare Safety Network Standardized Antimicrobial Administration Ratios (SAARs): A Progress Report and Risk Modeling Update Using 2017 Data.

Background: The Standardized Antimicrobial Administration Ratio (SAAR) is a risk-adjusted metric of antimicrobial use (AU) developed by the Centers for Disease Control and Prevention (CDC) in 2015 as a tool for hospital antimicrobial stewardship programs (ASPs) to track and compare AU with a national benchmark. In 2018, CDC updated the SAAR by expanding the locations and antimicrobial categories for which SAARs can be calculated and by modeling adult and pediatric locations separately.

Methods: We identified eligible patient-care locations and defined SAAR antimicrobial categories.

Inpatient Management of Uncomplicated Skin and Soft Tissue Infections in 34 Veterans Affairs Medical Centers: A Medication Use Evaluation.

Background: Skin and soft tissue infections (SSTIs) are a key antimicrobial stewardship target because they are a common infection in hospitalized patients, and non-guideline-concordant antibiotic use is frequent. To inform antimicrobial stewardship interventions, we evaluated the proportion of veterans hospitalized with SSTIs who received guideline-concordant empiric antibiotics or an appropriate total duration of antibiotics.

Methods: A retrospective medication use evaluation was performed in 34 Veterans Affairs Medical Centers between 2016 and 2017.

Collaborative Solutions to Antibiotic Stewardship in Small Community and Critical Access Hospitals.

The overuse and misuse of antibiotics affect patients in many ways, including by driving antibiotic resistance, a serious public health threat in the United States and around the world. To improve patient safety and address rising rates of resistance, an increasing number of health care facilities have created antibiotic stewardship programs (ASPs). ASPs have been successful in slowing the emergence of resistance and improving patient outcomes.

Leading Practices in Antimicrobial Stewardship: Conference Summary.

Unlabelled: The Joint Commission's hospital antimicrobial stewardship (AS) standards became effective in January 2017. Surveyors' experience to date suggests that almost all hospitals have established AS leadership commitment and organized structures. Thus, The Joint Commission sought to examine advances in AS interventions and measures that hospitals could implement to strengthen their existing AS programs.

Using NHSN's Antimicrobial Use Option to Monitor and Improve Antibiotic Stewardship in Neonates.

Background: The Antimicrobial Use (AU) Option of the Centers for Disease Control and Prevention's National Healthcare Safety Network (NHSN) is a surveillance resource that can provide actionable data for antibiotic stewardship programs. Such data are used to enable measurements of AU across hospitals and before, during, and after stewardship interventions.

Methods: We used monthly AU data and annual facility survey data submitted to the NHSN to describe hospitals and neonatal patient care locations reporting to the AU Option in 2017, examine frequencies of most commonly reported agents, and analyze variability in AU rates across hospitals and levels of care.

Evaluation of uncomplicated acute respiratory tract infection management in veterans: A national utilization review.
