Twenty of 21 health systems and network-based antimicrobial stewardship programs (ASPs) who were invited participated in a questionnaire, a webinar, and focus groups to understand implementation strategies for system-wide antimicrobial stewardship. Four centralized ASPs structures emerged. Of participating organizations, 3 (15%) confirmed classification as collaborative, 3 (15%) as centrally coordinated, 3 (15%) as in between or in transition between centrally coordinated and centrally led, 8 (40%) as centrally led, 2 (10%) as collaborative, consultative network. One (5%) organization considered themselves to be a hybrid. System-level stewardship responsibilities varied across sites and generally fell into 6 major categories: building and leading a stewardship community, strategic planning and goal setting, development of validated data streams, leveraging tools and technology for stewardship interventions, provision of subject-matter expertise, and communication/education. Centralized ASPs included in this study most commonly took a centrally led approach and engaged in activities tailored to system-wide goals.

Background 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. Methods The Joint Commission and Pew Charitable Trusts sponsored a meeting to bring together experts and key stakeholder organizations from around the country to identify leading practices for AS interventions and measurement. Presenters were asked to summarize the AS activities they thought were most important for the success of their own AS program and leading practices that all hospitals should be able to implement. Results The panel highlighted two interventions as leading practices that go beyond current guidelines and established practices (that is, preauthorization and prospective audit and feedback). The first is diagnostic stewardship. This type of intervention addresses errors in diagnostic decision making that lead to inappropriate antibiotic prescribing. The second is handshake stewardship, a method of engaging frontline providers on a regular basis for education and discussions about barriers to AS from the clinician's perspective. The panel identified days of therapy (or defined daily dose, when days of therapy is not possible), Clostridioides difficile rates, and adherence to facility-specific guidelines as the preferred measures for assessing stewardship activities. Conclusion The practices highlighted should be given greater emphasis by The Joint Commission in their efforts to improve hospital AS, and the Centers for Disease Control and Prevention will be updating the Core Elements of Hospital Antibiotic Stewardship Programs.

BackgroundThis study reports estimates of the healthcare costs, length of stay, and mortality associated with infections due to multidrug-resistant bacteria among elderly individuals in the United States.MethodsWe conducted a retrospective cohort analysis of patients aged ≥65 admitted for inpatient stays in the Department of Veterans Affairs healthcare system between 1/2007–12/2018. We identified those with positive cultures for multidrug-resistant bacteria and matched each infected patient to ≤10 control patients. We then performed multivariable regression models to estimate the attributable cost and mortality due to the infection. We also constructed multistate models to estimate the attributable length of stay due to the infection. Finally, we multiplied these pathogen-specific attributable cost, length of stay, and mortality estimates by national case counts from hospitalized patients in 2017.ResultsOur cohort consisted of 87 509 patients with infections and 835 048 matched controls. Costs were higher for hospital-onset invasive infections, with attributable costs ranging from $22 293 (95% confidence interval: $19 101–$24 485) for methicillin-resistant Staphylococcus aureus (MRSA) to $57 390 ($34 070–$80 710) for carbapenem-resistant (CR) Acinetobacter. Similarly, for hospital-onset invasive infections, attributable mortality estimates ranged from 14.2% (12.2–16.2%) for MRSA to 24.1% (12.1–36.0%) for CR Acinetobacter. The aggregate cost of these infections was an estimated $1.9 billion ($1.3 billion–$2.5 billion) with 11 852 (8719–14 985) deaths and 448 224 (354 513–541 934) inpatient days in 2017.ConclusionsEfforts to prevent these infections due to multidrug-resistant bacteria could save a significant number of lives and healthcare resources.

Nonguideline antibiotic prescribing for the treatment of pediatric infections is common, but the consequences of inappropriate antibiotics are not well described.To evaluate the comparative safety and health care expenditures of inappropriate vs appropriate oral antibiotic prescriptions for common outpatient pediatric infections.This cohort study included children aged 6 months to 17 years diagnosed with a bacterial infection (suppurative otitis media [OM], pharyngitis, sinusitis) or viral infection (influenza, viral upper respiratory infection [URI], bronchiolitis, bronchitis, nonsuppurative OM) as an outpatient from April 1, 2016, to September 30, 2018, in the IBM MarketScan Commercial Database. Data were analyzed from August to November 2021.Inappropriate (ie, non-guideline-recommended) vs appropriate (ie, guideline-recommended) oral antibiotic agents dispensed from an outpatient pharmacy on the date of infection.Propensity score-weighted Cox proportional hazards models were used to estimate hazards ratios (HRs) and 95% CIs for the association between inappropriate antibiotic prescriptions and adverse drug events. Two-part models were used to calculate 30-day all-cause attributable health care expenditures by infection type. National-level annual attributable expenditures were calculated by scaling attributable expenditures in the study cohort to the national employer-sponsored insurance population.The cohort included 2 804 245 eligible children (52% male; median [IQR] age, 8 [4-12] years). Overall, 31% to 36% received inappropriate antibiotics for bacterial infections and 4% to 70% for viral infections. Inappropriate antibiotics were associated with increased risk of several adverse drug events, including Clostridioides difficile infection and severe allergic reaction among children treated with a nonrecommended antibiotic agent for a bacterial infection (among patients with suppurative OM, C. difficile infection: HR, 6.23; 95% CI, 2.24-17.32; allergic reaction: HR, 4.14; 95% CI, 2.48-6.92). Thirty-day attributable health care expenditures were generally higher among children who received inappropriate antibiotics, ranging from $21 to $56 for bacterial infections and from -$96 to $97 for viral infections. National annual attributable expenditure estimates were highest for suppurative OM ($25.3 million), pharyngitis ($21.3 million), and viral URI ($19.1 million).In this cohort study of children with common infections treated in an outpatient setting, inappropriate antibiotic prescriptions were common and associated with increased risks of adverse drug events and higher attributable health care expenditures. These findings highlight the individual- and national-level consequences of inappropriate antibiotic prescribing and further support implementation of outpatient antibiotic stewardship programs.

ObjectivesAt least 30% of outpatient antibiotic prescriptions are unnecessary. Outpatient antibiotic stewardship is needed to improve prescribing and address the threat of antibiotic resistance. A better understanding of primary care physicians (PCPs) attitudes towards antibiotic prescribing and outpatient antibiotic stewardship is needed to identify barriers to stewardship implementation and help tailor stewardship strategies. The aim of this study was to assess PCPs current attitudes towards antibiotic resistance, inappropriate antibiotic prescribing and the feasibility of outpatient stewardship efforts.DesignEight focus groups with PCPs were conducted by an independent moderator using a moderator guide. Focus groups were audio recorded, transcribed and coded for major themes using deductive and inductive content analysis methods.SettingFocus groups were conducted in four US cities: Philadelphia, Birmingham, Chicago and Los Angeles.ParticipantsTwo focus groups were conducted in each city—one with family medicine and internal medicine physicians and one with paediatricians. A total of 26 family medicine/internal medicine physicians and 26 paediatricians participated.ResultsParticipants acknowledged that resistance is an important public health issue, but not as important as other pressing problems (eg, obesity, opioids). Many considered resistance to be more of a hospital issue. While participants recognised inappropriate prescribing as a problem in outpatient settings, many felt that the key drivers were non-primary care settings (eg, urgent care clinics, retail clinics) and patient demand. Participants reacted positively to stewardship efforts aimed at educating patients and clinicians. They questioned the validity of antibiotic prescribing metrics. This scepticism was due to a number of factors, including the feasibility of capturing prescribing quality, a belief that physicians will ‘game the system’ to improve their measures, and dissatisfaction and distrust of quality measurement in general.ConclusionsStakeholders will need to consider physician attitudes and beliefs about antibiotic stewardship when implementing interventions aimed at improving prescribing.

The prevalence of pediatric antimicrobial stewardship programs (ASPs) is increasing. We review strategies for ASPs to adapt and report standardized metrics, expand activities to specialized populations, and implement novel diagnostics for continued progress in improving antibiotic use and patient outcomes., The prevalence of pediatric antimicrobial stewardship programs (ASPs) is increasing in acute care facilities across the United States. Over the past several years, the evidence base used to inform effective stewardship practices has expanded, and regulatory interest in stewardship programs has increased. Here, we review approaches for established, hospital-based pediatric ASPs to adapt and report standardized metrics, broaden their reach to specialized populations, expand to undertake novel stewardship initiatives, and implement rapid diagnostics to continue their evolution in improving antimicrobial use and patient outcomes.

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. However, there are serious geographic and resource barriers to ASP adoption in small community hospitals and critical access hospitals. Fortunately, many barriers can be overcome by using collaborative models to bring together key stakeholders, including large hospitals and health systems and academic medical centers; hospital associations; federal, state, and local public health organizations; and federal and state offices of rural health. These stakeholders are ideally positioned to assist with stewardship efforts in small community and critical access hospitals and, in doing so, can improve patient safety while stemming the spread of resistant bacteria.

Using the 2014 IBM MarketScan commercial database, we compared antibiotic selection for pharyngitis, sinusitis, and acute otitis media in retail clinics, emergency departments, urgent care centers, and offices. Only 50% of visits for these conditions received recommended first-line antibiotics. Improving antibiotic selection for common outpatient conditions is an important stewardship target.

This cohort study compares antibiotic prescribing in 2014 among retail clinics, urgent care centers, emergency departments, and traditional medical offices in the United States.

Antibiotic-resistant infections pose a growing threat to public health. Antibiotic use, regardless of whether it is warranted, is a primary factor in the development of resistance. In the United States, the majority of antibiotic health care expenditures are due to prescribing in outpatient settings. Much of this prescribing is inappropriate, with research showing that at least 30% of antibiotic use in outpatient settings is unnecessary. In this State of the Art Review article, we provide an overview of the latest research on outpatient antibiotic prescribing practices in the United States. Although many of the researchers in these studies describe antibiotic prescribing across all patient age groups, we highlight prescribing in pediatric populations when data are available. We then describe the various factors that can influence a physician’s prescribing decisions and drive inappropriate antibiotic use and the potential role of behavioral science in enhancing stewardship interventions to address these drivers. Finally, we highlight the role that a wide range of health care stakeholders can play in aiding the expansion of outpatient stewardship efforts that are needed to fully address the threat of antibiotic resistance.

Antibiotic stewardship programs (ASPs) improve antibiotic prescribing. Seventy-three percent of US hospitals have

The outcome of patients who were treated with oral trimethoprim-sulfamethoxazole or oral clindamycin after hospitalization at Texas Children's Hospital for community-acquired methicillin-resistant Staphylococcus aureus skin and soft tissue infections was compared. No significant differences were observed in the percentage of patients who returned to the emergency center or clinics because of worsening or incomplete resolution of the infected site.

Antimicrobial stewardship (AS) programs are effective in improving clinical outcomes associated with antimicrobial therapies while improving patient safety by reducing adverse events and development of bacterial resistance. Understanding the basic principles of AS is essential to the successful development and implementation of AS strategies. Identifying and developing strategies to address barriers and challenges to AS can facilitate the establishment of financial, administrative, and organizational support, and agreement and participation by individual prescribers. Review of published outcomes of AS demonstrates the effectiveness in reducing unnecessary antimicrobial use and adverse events such as Clostridium difficile infections. We also illustrate the need for further research and expansion of AS activities to office-based practices and communities by using novel and innovative AS strategies and by influencing regional and national policies.

An adolescent with recently removed ureteral stents and exposure to toilet water contaminated with sink flies developed urinary myiasis after stent removal. Poor hygiene, urinary obstruction and retention and decreased general health are known risk factors for developing urinary myiasis. Good hygiene and sanitation practices should be emphasized to patients with indwelling urogenital foreign bodies such as ureteral stents.

Importance The National Action Plan for Combating Antibiotic-Resistant Bacteria set a goal of reducing inappropriate outpatient antibiotic use by 50% by 2020, but the extent of inappropriate outpatient antibiotic use is unknown. Objective To estimate the rates of outpatient oral antibiotic prescribing by age and diagnosis, and the estimated portions of antibiotic use that may be inappropriate in adults and children in the United States. Design, Setting, and Participants Using the 2010-2011 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, annual numbers and population-adjusted rates with 95% confidence intervals of ambulatory visits with oral antibiotic prescriptions by age, region, and diagnosis in the United States were estimated. Exposures Ambulatory care visits. Main Outcomes and Measures Based on national guidelines and regional variation in prescribing, diagnosis-specific prevalence and rates of total and appropriate antibiotic prescriptions were determined. These rates were combined to calculate an estimate of the appropriate annual rate of antibiotic prescriptions per 1000 population. Results Of the 184 032 sampled visits, 12.6% of visits (95% CI, 12.0%-13.3%) resulted in antibiotic prescriptions. Sinusitis was the single diagnosis associated with the most antibiotic prescriptions per 1000 population (56 antibiotic prescriptions [95% CI, 48-64]), followed by suppurative otitis media (47 antibiotic prescriptions [95% CI, 41-54]), and pharyngitis (43 antibiotic prescriptions [95% CI, 38-49]). Collectively, acute respiratory conditions per 1000 population led to 221 antibiotic prescriptions (95% CI, 198-245) annually, but only 111 antibiotic prescriptions were estimated to be appropriate for these conditions. Per 1000 population, among all conditions and ages combined in 2010-2011, an estimated 506 antibiotic prescriptions (95% CI, 458-554) were written annually, and, of these, 353 antibiotic prescriptions were estimated to be appropriate antibiotic prescriptions. Conclusions and Relevance In the United States in 2010-2011, there was an estimated annual antibiotic prescription rate per 1000 population of 506, but only an estimated 353 antibiotic prescriptions were likely appropriate, supporting the need for establishing a goal for outpatient antibiotic stewardship.
