Antimicrobial resistance is a global public health threat. Antimicrobial-resistant infections are on the rise and are associated with increased morbidity, mortality, and health care costs. Infants and children are affected by transmission of antimicrobial-resistant zoonotic pathogens through the food supply, direct contact with animals, environmental pathways, and contact with infected or colonized humans. Although the judicious use of antimicrobial agents is necessary for maintaining the health and welfare of humans and animals, it must be recognized that all use of antimicrobial agents exerts selective pressure that increases the risk of development of resistance. This report describes historical and recent use of antibiotics in animal agriculture, reviews the mechanisms of how such use contributes to development of resistance and can adversely affect child health, and discusses US initiatives to curb unnecessary use of antimicrobial agents in agriculture.

Antimicrobial drug use (AMU) in veterinary medicine may contribute to antimicrobial resistant (AMR) infections in both animals and people. Efforts to improve AMU in companion animal medicine are underway and should include all members of the veterinary team, including veterinary support staff. Our objective was to describe knowledge and attitudes regarding AMU, AMR, and antimicrobial stewardship (AMS) in companion animal medicine among veterinary support staff professionals in the United States using an anonymous, online questionnaire. Additionally, we sought to explore veterinary support staff perceptions of their role in the antimicrobial drug (AMD) prescribing process. Veterinary technicians, nurses, assistants, client care representatives, and hospital managers (n = 337) considered AMR a global concern (83.4%), and 40% reported receiving AMR education from their employer. Few (18.3%) were aware of AMS, with only 6.4% indicating that their clinic had an AMS program. Frequent involvement in the AMD prescribing process was reported (43.4%), but only 19.7% perceived involvement with AMS interventions. Approximately one-third of participants (34.9%) said that advice regarding the need for AMDs was routinely provided by staff to pet owners prior to veterinary consultation. Participants estimated that 82.6% of all AMD prescriptions were filled at the clinic as opposed to an outside pharmacy. Given their direct involvement in the AMD prescribing process and frequent interactions with pet owners, AMS should be emphasized to all veterinary staff. Involving support staff in AMS interventions is necessary to improve AMU in companion animal medicine. [ABSTRACT FROM AUTHOR]

Background No national study has evaluated changes in the appropriateness of US outpatient antibiotic prescribing across all conditions and age groups after the coronavirus disease 2019 (COVID-19) outbreak in March 2020. Methods This was an interrupted time series analysis of Optum's de-identified Clinformatics Data Mart Database, a national commercial and Medicare Advantage claims database. Analyses included prescriptions for antibiotics dispensed to children and adults enrolled during each month during 2017–2021. For each prescription, we applied our previously developed antibiotic appropriateness classification scheme to International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes on medical claims occurring on or during the 3 days prior to dispensing. Outcomes included the monthly proportion of antibiotic prescriptions that were inappropriate and the monthly proportion of enrollees with ≥1 inappropriate prescription. Using segmented regression models, we assessed for level and slope changes in outcomes in March 2020. Results Analyses included 37 566 581 enrollees, of whom 19 154 059 (51.0%) were female. The proportion of enrollees with ≥1 inappropriate prescription decreased in March 2020 (level decrease: −0.80 percentage points [95% confidence interval {CI}, −1.09% to −.51%]) and subsequently increased (slope increase: 0.02 percentage points per month [95% CI,.01%–.03%]), partly because overall antibiotic dispensing rebounded and partly because the proportion of antibiotic prescriptions that were inappropriate increased (slope increase: 0.11 percentage points per month [95% CI,.04%–.18%]). In December 2021, the proportion of enrollees with ≥1 inappropriate prescription equaled the corresponding proportion in December 2019. Conclusions Despite an initial decline, the proportion of enrollees exposed to inappropriate antibiotics returned to baseline levels by December 2021. Findings underscore the continued importance of outpatient antibiotic stewardship initiatives. [ABSTRACT FROM AUTHOR]

In a retrospective, ecological analysis of US medical claims, visit rates explained more of the geographic variation in outpatient antibiotic prescribing rates than per-visit prescribing. Efforts to reduce antibiotic use may benefit from addressing the factors that drive higher rates of outpatient visits, in addition to continued focus on stewardship. [ABSTRACT FROM AUTHOR]

Clostridioides difficile infection is the most common healthcare-associated infection in the United States, with potential life-threatening complications and a significant impact on the costs of care. Antibiotic stewardship as well as discontinuation of chronic acid suppressive therapy are key for its prevention and treatment. Effective infection management requires appropriate interpretation of diagnostic tests, as well as the use of vancomycin and fidaxomicin as first-line treatment. Novel treatments such as Bezlotoxumab, fecal microbiota transplant, and live biotherapeutic products are proven effective in recurrent C. difficile infection and address dysbiosis.

Coccidioidomycosis poses a significant cost and morbidity burden in the United States. Additionally, coccidioidomycosis requires constant decision-making related to prevention, diagnosis, and management. Delays in diagnosis lead to significant consequences, including unnecessary diagnostic workup and antibacterial therapy. Antifungal stewardship considerations regarding empiric, prophylactic, and targeted management of coccidioidomycosis are also complex. In this review, the problems facing antimicrobial stewardship programs (ASPs) in the endemic region for coccidioidomycosis, consequences due to delayed or missed diagnoses of coccidioidomycosis on antibacterial prescribing, and excess antifungal prescribing for prevention and treatment of coccidioidomycosis are elucidated. Finally, our recommendations and research priorities for ASPs in the endemic region for coccidioidomycosis are outlined. [ABSTRACT FROM AUTHOR]

The US healthcare system's contribution to greenhouse gas emissions and climate change is disproportionately high and harms the public. Several medical specialties are now reassessing how they can mitigate healthcare's harmful environmental impact. Healthcare sustainability is broadly defined as measures to decrease greenhouse gas emissions, waste, and other pollutants generated during the healthcare delivery process. Prior efforts and programs by infectious diseases (ID) professionals, such as antimicrobial stewardship and infection prevention and control can form a framework for ID professionals to help apply this expertise to healthcare environmental sustainability more broadly. This call to action proposes strategies for ID societies and professionals to incorporate climate change education for trainees, increase research and funding opportunities in healthcare sustainability, and calls for action by ID societies to champion system changes to decrease greenhouse gas emissions.

An introduction is presented which discusses article on several topics including antimicrobial stewardship as a response to Antimicrobial resistance, exploring correctness, optimization, and moderation in antimicrobial use, framed within ethical considerations, conservation, and sustainability.

The field of infectious diseases saw numerous exciting advances in 2023. Trials of new antibiotics and treatment regimens sought to address rising rates of antimicrobial resistance. Other studies focused on the most appropriate use of currently available treatments, balancing the dual goals of providing effective treatment and impactful antimicrobial stewardship. Improvements in disease prevention were made through trials of both new vaccines and new chemoprophylaxis approaches. Concerning trends this year included increasing rates of invasive group A streptococcal infections, medical tourism-associated cases of fungal meningitis, and the return of locally acquired malaria to the United States. This review covers some of these notable trials and clinical developments in infectious diseases in the past year. [ABSTRACT FROM AUTHOR]

Dermatophytoses are fungal infections of the skin, hair, and nails that affect approximately 25% of the global population. Occlusive clothing, living in a hot humid environment, poor hygiene, proximity to animals, and crowded living conditions are important risk factors. Dermatophyte infections are named for the anatomic area they infect, and include tinea corporis, cruris, capitis, barbae, faciei, pedis, and manuum. Tinea incognito describes steroid-modified tinea. In some patients, especially those who are immunosuppressed or who have a history of corticosteroid use, dermatophyte infections may spread to involve extensive skin areas, and, in rare cases, may extend to the dermis and hair follicle. Over the past decade, dermatophytoses cases not responding to standard of care therapy have been increasingly reported. These cases are especially prevalent in the Indian subcontinent, and Trichophyton indotineae has been identified as the causative species, generating concern regarding resistance to available antifungal therapies. Antifungal-resistant dermatophyte infections have been recently recognized in the United States. Antifungal resistance is now a global health concern. When feasible, mycological confirmation before starting treatment is considered best practice. To curb antifungal-resistant infections, it is necessary for physicians to maintain a high index of suspicion for resistant dermatophyte infections coupled with antifungal stewardship efforts. Furthermore, by forging partnerships with federal agencies, state and local public health agencies, professional societies, and academic institutions, dermatologists can lead efforts to prevent the spread of antifungal-resistant dermatophytes.

Background The BioFire FilmArray Pneumonia Panel (BFPP), a multiplex PCR panel for the diagnosis of lower respiratory tract infections, has been proposed as a tool for antimicrobial stewardship. Few studies evaluate real-world implementation of the BFPP and no studies focus exclusively on children. Our institution implemented BFPP testing without restrictions. Methods We conducted a retrospective cohort study in children hospitalized at St. Louis Children's Hospital to (1) characterize the use of the BFPP in pediatric patients and (2) assess how results impacted antibiotic use. We included all BFPP tests obtained during the first year after the introduction of the test, September 2021 through August 2022. The primary outcome was change in antibiotic therapy within 24 hours of results, which was compared to the potential change in antibiotic therapy determined by two infectious diseases clinicians. Results One hundred sixty-nine tests from 126 patients were included. Nine patients were immunocompromised and 19 had chronic tracheostomy. The majority of tests were sent from tracheal aspirate specimens (92%) and from patients in an intensive care unit (94%). Only 51% of tests were obtained due to respiratory failure or suspected pneumonia. For 80% of test results, there was potential to change antibiotics, but change occurred in only 46% of tests in practice. Antibiotic escalation was more common (26%) than de-escalation (15%) or discontinuation (4.1%). Conclusions In a cohort of pediatric patients tested with the BFPP, the majority of tests were sent from tracheal aspirates and less than half of tests were associated with a change in antibiotics.

Dentists are an overlooked group of prescribers but are responsible for up to 10% of antibiotic prescriptions written in the United States annually, most of which are for prophylaxis. Dental prophylaxis in orthopedic patients has been an area of confusion, with discordance among societal guidelines. In 2020, an antimicrobial stewardship (AS) group spearheaded a collaborative effort among dental, orthopedic surgery, and infectious diseases specialties to develop a protocol for the use of dental antibiotic prophylaxis for patients with total joint replacements (TJRs) based on the most current American Dental Association-American Academy of Orthopaedic Surgeons statement. This study aimed to assess antibiotic prescribing for dental prophylaxis before and after an AS intervention. This study is an interventional, pre-post review of dental encounters with patients with a history of TJR before (October 2019 to July 2021) and after (August 2021 to April 2023) the intervention. Charts were reviewed to determine the frequency and appropriateness of dental procedure prophylactic antibiotics. A total of 1587 encounters from October 2019 to April 2023 were identified. Notably, 179 encounters in the pre- and 183 encounters in the postgroup were analyzed, 31 encounters (17%) in the pregroup versus 33 (18%) in the postgroup had a prophylactic antibiotic associated with it (P > 0.05), 26 of 31 antibiotics (84%) in the pregroup were prescribed for prosthetic joint infection prophylaxis compared with 18 of 33 (55%) in the postgroup (P > 0.05), and 151 of 179 encounters (84.3%) were guideline adherent in the preintervention group compared with 160 of 183 encounters (87.4%) in the postintervention group (P > 0.05). This study observed a shift in the distribution of antibiotic indications and a decreased rate of inappropriate prophylactic prescriptions in dental patients with a history of TJR after an AS-led, collaborative intervention. Although the overall rate of prophylactic antibiotic prescribing remained the same and the changes did not reach statistical significance, lessons learned through this process can help inform future interventions in our institution and for others.

Background Blood culture contamination (BCC) has been associated with prolonged antibiotic use (AU) and increased health care utilization; however, this has not been widely reevaluated in the era of increased attention to antibiotic stewardship. We evaluated the impact of BCC on AU, resource utilization, and length of stay in Dutch and US patients. Methods This retrospective observational study examined adults admitted to 2 hospitals in the Netherlands and 5 hospitals in the United States undergoing ≥2 blood culture (BC) sets. Exclusion criteria included neutropenia, no hospital admission, or death within 48 hours of hospitalization. The impact of BCC on clinical outcomes—overall inpatient days of antibiotic therapy, test utilization, length of stay, and mortality—was determined via a multivariable regression model. Results An overall 22 927 patient admissions were evaluated: 650 (4.1%) and 339 (4.8%) with BCC and 11 437 (71.8%) and 4648 (66.3%) with negative BC results from the Netherlands and the United States, respectively. Dutch and US patients with BCC had a mean ± SE 1.74 ± 0.27 (P <.001) and 1.58 ± 0.45 (P <.001) more days of antibiotic therapy than patients with negative BC results. They also had 0.6 ± 0.1 (P <.001) more BCs drawn. Dutch but not US patients with BCC had longer hospital stays (3.36 days; P <.001). There was no difference in mortality between groups in either cohort. AU remained higher in US but not Dutch patients with BCC in a subanalysis limited to BC obtained within the first 24 hours of admission. Conclusions BCC remains associated with higher inpatient AU and health care utilization as compared with patients with negative BC results, although the impact on these outcomes differs by country.

Purpose: To summarize the most noteworthy infectious diseases (ID) pharmacotherapy articles published in peer-reviewed literature in 2021. Summary: Members of the Houston Infectious Diseases Network (HIDN) nominated articles that were deemed to have significant contributions to ID pharmacotherapy in 2021. These nominations included articles pertaining to both general ID, including coronavirus disease 2019 (COVID-19), and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) pharmacotherapy. A total of 35 articles were nominated by HIDN: 30 articles pertaining to general ID pharmacotherapy and 5 articles with HIV/AIDS focus. To select the most influential articles of 2021, a survey was created and distributed to members of the Society of Infectious Diseases Pharmacists (SIDP). Of the 239 SIDP members who responded to the survey, there were 192 recorded votes for the top 10 general ID pharmacotherapy articles and 47 recorded votes for the top HIV/AIDS article, respectively. The top publications are summarized. Conclusion: Antimicrobial stewardship and the optimal management of infectious disease states continues to be a priority in the midst of the ongoing coronavirus disease 2019 (COVID-19) global pandemic. In light of the sheer volume of ID-related articles published in the past year, this review aims to aid clinicians in remaining up-to-date on key practice-changing ID pharmacotherapy publications from 2021.

Purpose Emergency department (ED) pharmacists commonly perform positive culture follow-ups that result in optimized antibiotic prescribing. The purpose of this study was to evaluate the potential positive impact on the outcome of antibiotic-free days through an ED pharmacist–driven protocol to contact patients with negative urine cultures and sexually transmitted infection (STI) test results who were discharged with antibiotics. Methods This was a single-center, prospective, observational, pre-post intervention study to determine antibiotic use in patients with negative urine cultures who were discharged from the Loyola Medical University Center ED with antibiotics prescribed. Patients were identified through daily positive culture reports. The primary outcome was days free of antibiotics, defined as the number of calendar days within 28 days after urine culture or STI test collection on which the patient did not receive any antibiotic treatments. Results One hundred ninety-two patients were screened. Sixty-three and twenty-six patients met the inclusion criteria in the pre- and postintervention groups, respectively. The study identified 163/465 (35.1%) antibiotic free days for the preintervention group, compared to 150.5/187 (80.5%) antibiotic-free days for the postintervention group. A majority of the patients did not have urinary tract infection as the chief complaint. The most common urinary and STI symptoms upon ED admission in the pre- and postintervention groups were dysuria (19.2% vs 28.1%) and unusual discharge (30.8% vs 28.6%), respectively. Conclusion This study showed that a pharmacist-driven protocol increased the number of antibiotic-free days for patients prescribed empiric antibiotic therapy and discharged from the ED with subsequent negative urine cultures and STI results. We propose taking a novel approach in discontinuation of antibiotics by implementing an expansion of ED culture programs to include negative cultures that promote antimicrobial stewardship.

In a cross-sectional survey of US acute care hospitals, antimicrobial stewardship programs were present in most Veterans Affairs and nonfederal hospitals but varied in team composition, scope, and impact. Diagnostic stewardship was common across hospitals. Veterans Affairs hospitals had increased reach in outpatient settings. Telestewardship remains an opportunity in all hospital systems.

Background Antimicrobial stewardship (AS) is an important topic in infectious diseases (ID) training, yet many ID fellowships lack formal training, and little is known about fellows' learning preferences. Methods We conducted 24 in-depth interviews with ID fellows across the United States during 2018 and 2019 to explore their experiences with and preferences for AS education during fellowship. Interviews were transcribed, deidentified, and analyzed to identify themes. Results Fellows had variable exposure to AS before and during fellowship, which impacted their knowledge about and attitude toward stewardship as a career; however, all fellows expressed the importance of learning general stewardship principles during fellowship. Some fellows' training included mandatory stewardship lectures and/or rotations, but most fellows felt their primary stewardship learning occurred through informal experiences in the clinical setting, such as holding the antimicrobial approval pager. Fellows expressed a preference for a standardized, structured curriculum that included in-person practical, interactive discussions with multidisciplinary faculty along with the opportunity to practice and apply their skills; however, they emphasized that time needed to be set aside for those educational activities. Although they wanted to learn the evidence and rationale for stewardship recommendations, they especially wanted training in and feedback on how to communicate stewardship recommendations to other health professionals, particularly in the setting of conflict. Conclusions ID fellows believe that standardized AS curricula should be included in their fellowship training, and they prefer structured, practical, and interactive learning experiences.

In the United States, approximately 27 million people have a documented penicillin allergy, but 90% of the allergies are falsely labeled. By rechallenging suspected allergies, a pharmacist can optimize patient care, fulfill antimicrobial stewardship objectives, and educate patients on true allergies. We suggest a protocol that allows pharmacists to investigate the presence of an allergy and conduct a challenge when indicated. The protocol consists of a patient interview, a risk assessment, an oral rechallenge, and the potential for a skin test. The testing and delabeling of penicillin allergies will enhance the practice of antimicrobial stewardship in the outpatient setting. In the changing landscape of pharmacy, community pharmacists can increase their services and improve patient care. Owing to limited documented experience in the outpatient pharmacy, an opportunity to set the standard and be a leader in the field is present. [ABSTRACT FROM AUTHOR]

By fall 2020, students returning to U.S. university campuses were mandated to engage in COVID-19 mitigation behaviors, including masking, which was a relatively novel prevention behavior in the U.S. Masking became a target of university mandates and campaigns, and it became politicized. Critical questions are whether the influences of injunctive norms and response efficacy on one behavior (i.e. masking) spill over to other mitigation behaviors (e.g. hand-washing), and how patterns of mitigation behaviors are associated with clinical outcomes. We conducted a cross-sectional survey of college students who returned to campus (N = 837) to explore these questions, and conducted COVID-19 antibody testing on a subset of participants to identify correlations between behaviors and disease burden. The results showed that college students were more likely to intend to wear face masks as they experienced more positive injunctive norms, liberal political views, stronger response efficacy for masks, and less pessimism. Latent class analysis revealed four mitigation classes: Adherents who intended to wear face masks and engage in the other COVID-19 mitigation behaviors; Hygiene Stewards and Masked Symptom Managers who intended to wear masks but only some other behaviors, and Refusers who intended to engage in no mitigation behaviors. Importantly, the Hygiene Stewards and Refusers had the highest likelihood of positive antibodies; these two classes differed in their masking intentions, but shared very low likelihoods of physical distancing from others and avoiding crowds or mass gatherings. The implications for theories of normative influences on novel behaviors, spillover effects, and future messaging are discussed. [ABSTRACT FROM AUTHOR]

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. Differences in antibiotic prescribing were found by patient's race and ethnicity, sex, age, socioeconomic factors, geography, clinician's age and specialty, and healthcare setting, with an emphasis on outpatient settings. Few studies assessed stewardship interventions. Clinicians, antibiotic stewardship experts, and health systems should be aware that prescribing behavior varies according to both clinician- and patient-level markers. Prescribing differences likely represent structural inequities; however, no studies reported underlying drivers of inequities in antibiotic prescribing. [ABSTRACT FROM AUTHOR]

Using antibiotics without medical guidance (non-prescription antibiotic use) may contribute to antimicrobial resistance. Hispanic individuals are a growing demographic group in the United States (US) with a high prevalence of non-prescription antibiotic use. We investigated the effects of acculturation and subjective norms on Hispanic individuals' intentions to use antibiotics without a prescription from the following sources: (1) markets in the United States (not legal), (2) other countries (abroad), (3) leftovers from previous prescriptions, and (4) friends/relatives. We surveyed self-identified Hispanic outpatients in eight clinics from January 2020 to June 2021 using the previously validated Short Acculturation Scale for Hispanics (SASH). Of the 263 patients surveyed, 47% reported previous non-prescription use, and 54% expressed intention to use non-prescription antibiotics if feeling sick. Individuals with lower acculturation (Spanish-speaking preferences) expressed greater intentions to use antibiotics from abroad and from any source. Individuals with more friends/relatives who obtain antibiotics abroad were over 2.5 times more likely to intend to use non-prescription antibiotics from friends/relatives (p = 0.034). Other predictors of intention to use non-prescription antibiotics included high costs of doctor visits and perceived language barriers in the clinic. Antibiotic stewardship interventions in Hispanic communities in the United States should consider the sociocultural and healthcare barriers influencing non-prescription use and promote language-concordant healthcare.

In this national cohort of older adults residing long-term in US nursing homes between 2013 and 2017, we calculated period prevalence estimates for antibiotic prescribing, rates of prescribing, and days of therapy. Among 1 375 062 residents, 66.2% were prescribed at least 1 antibiotic during the nursing home stay. The most prevalent antibiotic classes were fluoroquinolones, sulfonamides and related agents, and first-generation cephalosporins. Levofloxacin, ciprofloxacin, and sulfamethoxazole-trimethoprim were the most prevalent antibiotics. These results can inform antibiotic stewardship interventions to reduce antibiotic overprescribing, improve appropriateness, and reduce related adverse outcomes in nursing homes.

To assess knowledge, attitudes, and practices (KAP) related to antimicrobial resistance (AMR) among college students. Undergraduate students at a large public university in the United States. Anonymous online questionnaire completed in early 2020. While 82% of participants knew that resistant pathogens can spread between people, 38% believed that antibiotics weaken the immune system and 32% believed that AMR is only a problem for people who take antibiotics often. Many undergraduates have or would stop taking antibiotics before completing a full course because of side effects (44%) or feeling better (38%), and some would take (23%) or share (13%) antibiotics that had not been prescribed to the recipient. Only 57% are worried about AMR, compared to 88% who are worried about global climate change. Health education about antimicrobial stewardship and other global health issues must improve knowledge, perceptions, health behaviors, self-efficacy, and social norms. [ABSTRACT FROM AUTHOR]

Background Community-acquired pneumonia (CAP) is a leading cause of hospital admissions and antimicrobial use. Clinical practice guidelines recommend switching from intravenous (IV) to oral antibiotics once patients are clinically stable. Methods We conducted a retrospective cohort study of adults admitted with CAP and initially treated with IV antibiotics at 642 US hospitals from 2010 through 2015. Switching was defined as discontinuation of IV and initiation of oral antibiotics without interrupting therapy. Patients switched by hospital day 3 were considered early switchers. We compared length of stay (LOS), in-hospital 14-day mortality, late deterioration (intensive care unit [ICU] transfer), and hospital costs between early switchers and others, controlling for hospital characteristics, patient demographics, comorbidities, initial treatments, and predicted mortality. Results Of 378 041 CAP patients, 21 784 (6%) were switched early, most frequently to fluoroquinolones. Patients switched early had fewer days on IV antibiotics, shorter duration of inpatient antibiotic treatment, shorter LOS, and lower hospitalization costs, but no significant excesses in 14-day in-hospital mortality or late ICU admission. Patients at a higher mortality risk were less likely to be switched. However, even in hospitals with relatively high switch rates, <15% of very low–risk patients were switched early. Conclusions Although early switching was not associated with worse outcomes and was associated with shorter LOS and fewer days on antibiotics, it occurred infrequently. Even in hospitals with high switch rates, <15% of very low–risk patients were switched early. Our findings suggest that many more patients could be switched early without compromising outcomes.

Background To address knowledge gaps in management of Gram-negative bloodstream infection, the Antibiotic Stewardship Implementation Collaborative was established consisting of programs from 24 academic and community hospitals across the United States. Methods A retrospective cohort study was conducted of unique adult patients with Gram-negative bloodstream infection hospitalized at participating hospitals from January to December 2019. Patient level and microbiologic data were collected via electronic medical record review with a standardized data collection form and data dictionary. Data analysis was largely descriptive. The Pearson χ2 test to compare categorical variables and the Wilcoxon rank sum test for continuous variables were used. Results In total, 4851 bacterial isolates from 3710 eligible unique patients were included in the cohort. Most common source of infection was the urinary tract (47.9%). Source control was achieved in 84% of cases. Escherichia coli (2471, 51.0%) was the most common Gram-negative organism recovered. Antibiogram combining isolates from all participating centers with species-level susceptibilities and source specific antibiograms for isolates from urinary, respiratory, and intraabdominal source were created. Northeast sites contributed the most extended spectrum beta-lactamase (ESBL) producing organisms (73%), but West sites had the highest percentage of ESBL producers of total isolates (16%). A statistically significant difference in percentage of ESBL-producing organisms in Whites vs. non-Whites (14.6 % and 9.5 %, respectively, P <0.01) was observed. Conclusions While the present study was conducted pre-pandemic, it highlights the need for stewardship data collaboratives to enhance our understanding of the antimicrobial resistance patterns.

Objective Antibiotic stewardship should be an essential component of neonatology training as neonatal intensive care units (NICU) have unique stewardship needs. Our aim was to assess neonatology fellowship trainees' knowledge, attitudes, and perceptions about antibiotic stewardship to inform sustainable curriculum development. Study Design We distributed an electronic survey to neonatology fellows in the United States over 4 months (January–April 2018) via Accreditation Council for Graduate Medical Education program directors. Results Of 99 programs in the United States with an estimated 700 fellows, 159 (23%) fellows from 52 training programs (53%) responded to the survey and 139 (87%) provided analyzed responses. Majority of respondents were training in southern (59; 42%) and northeastern (43; 31%) regions and were equally spread across all 3 years of training. One hundred (72%) respondents reported an antibiotic stewardship program (ASP) in their institution. While 86% (120/139) were able to identify the components of an ASP, 59% (82/139) either did not or were unsure if they had received antibiotic stewardship training during fellowship. Furthermore, while answering case studies, 124 (89%) respondents identified the optimal antibiotic for methicillin susceptible Staphylococcus aureus (MSSA) infection and 69 (50%) respondents chose appropriate empiric antibiotics for neonatal meningitis. Notably, fellowship training year was not significantly related to the proportion of incorrect knowledge responses (p = 0.40). Most survey respondents (81; 59%) identified small group sessions as the most useful teaching format, while others chose audit and feedback of individual prescribing behavior (52; 38%) and didactic lectures (52; 38%). Finally, ninety-five (69%) respondents preferred trainee-led ASP interventions targeting focal areas such as antifungal and surgical prophylaxis. Conclusion Antibiotic stewardship is a critical part of neonatology training. Neonatology fellows report variation in access to ASP during their training. Fellows prefer dedicated trainee-led interventions and stewardship curriculum taught within small group settings to promote targeted NICU ASP. Key Points Most neonatology programs expose trainees to internal or external antibiotic stewardship programs. Over half of fellow trainees are unsure about receiving targeted antibiotic stewardship training. Most neonatology fellows prefer a trainee-led antibiotic stewardship intervention.

Background There are limited US data assessing adherence to surgical antimicrobial prophylaxis guidelines, particularly across a large, nationwide sample. Moreover, commonly prescribed inappropriate antimicrobial prophylaxis regimens remain unknown, hindering improvement initiatives. Methods We conducted a retrospective cohort study of adults who underwent elective craniotomy, hip replacement, knee replacement, spinal procedure, or hernia repair in 2019–2020 at hospitals in the PINC AI (Premier) Healthcare Database. We evaluated adherence of prophylaxis regimens, with respect to antimicrobial agents endorsed in the American Society of Health-System Pharmacist guidelines, accounting for patient antibiotic allergy and methicillin-resistant Staphylococcus aureus colonization status. We used multivariable logistic regression with random effects by hospital to evaluate associations between patient, procedural, and hospital characteristics and guideline adherence. Results Across 825 hospitals and 521 091 inpatient elective surgeries, 308 760 (59%) were adherent to prophylaxis guidelines. In adjusted analysis, adherence varied significantly by US Census division (adjusted OR [aOR] range:.61–1.61) and was significantly lower in 2020 compared with 2019 (aOR:.92; 95% CI:.91–.94; P <.001). The most common reason for nonadherence was unnecessary vancomycin use. In a post hoc analysis, controlling for patient age, comorbidities, other nephrotoxic agent use, and patient and procedure characteristics, patients receiving cefazolin plus vancomycin had 19% higher odds of acute kidney injury (AKI) compared with patients receiving cefazolin alone (aOR: 1.19; 95% CI: 1.11–1.27; P <.001). Conclusions Adherence to antimicrobial prophylaxis guidelines remains suboptimal, largely driven by unnecessary vancomycin use, which may increase the risk of AKI. Adherence decreased in the first year of the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Most neonatologists will be named as a defendant in a medical malpractice lawsuit during their careers. Most are until it happens likely poorly prepared for the process. This article reviews common and uncommon situations that can result in adverse outcomes and potential liability for neonatologists and newborn providers and discusses ways to mitigate this risk in advance. The ramifications of a medical malpractice lawsuit and whether to settle the case out of court or going to trial, followed by potential review by the State's Medical Board are discussed. Finally, knowledge of the process before, rather than after it happens, may help to reduce the stress and uncertainty that naturally follows for the individual involved. [ABSTRACT FROM AUTHOR]

Purpose Clinical trials of procalcitonin (PCT)–based algorithms for antibacterial therapy have shown a reduction in antimicrobial use and improved survival. Translation of PCT algorithms to clinical settings has often been unsuccessful. We hypothesized that appropriate utilization of PCT could be improved by implementing an antimicrobial stewardship team (AST) approach to PCT testing. Methods We completed a pre-post intervention evaluation of adult patients admitted to the intensive care unit with a diagnosis of sepsis. The standard PCT algorithm period (SPAP) cohort included patients enrolled before dedicated AST involvement. During the AST-supported PCT algorithm period (ASPAP), the AST reviewed and provided feedback for all appropriate patients. The primary outcome was adherence to the PCT algorithm. Results Thirty-five and 57 patients were evaluated in the SPAP and ASPAP cohorts, respectively. There were no differences in demographics or infection site between the groups. Baseline PCT assessment was ordered in a larger proportion of patients in the ASPAP cohort (90% vs 57%; P = 0.0006). Follow-up PCT measurement was performed in more patients in the ASPAP cohort (76% vs 23%; P < 0.0001). Antibiotics were discontinued per algorithm in more patients in the ASPAP cohort (25/57 [44%] vs 2/35 [7%]; P < 0.0001). Patients in the ASPAP cohort experienced a shorter total duration of antibiotics (5 vs 7 days; P = 0.02), with no significant difference in length of stay or 30-day readmission or mortality between the cohorts. Conclusion A PCT algorithm successfully implemented by an AST was associated with a significant decrease in total antibiotic days with no differences in mortality or length of stay.

Purpose: Antimicrobial resistance poses a major threat to human health globally and antibiotic overuse is a main driver of resistance. Antimicrobial stewardship (AMS) was developed to improve the rationale use of antibiotics. The Choosing Wisely campaign was initiated to ameliorate medical practice through avoidance of unnecessary diagnostic and therapeutic procedures. Our objective was to give an overview on the Choosing Wisely recommendations related to AMS practices from a selection of different countries in order to define future needs. Methods: We evaluated the seven countries already analyzed for Choosing Wisely recommendations related to topics of infectious medicine before. Finally, we included five of the former countries (Australia/New Zealand, Canada, Italy, Switzerland, and USA) and Germany with easily accessible recommendations and selected those related to six categories of AMS as following: diagnostics, indication, choice of antiinfective drugs, dosing, application and duration of therapy. Results: In total, 213 recommendations could be extracted related to AMS for the six countries and were matched to the chosen categories. Interestingly, no recommendations were found for the category "dosing." Topics related to indication and diagnostics were most frequently found with 85 and 78 recommendations, respectively. Perioperative prophylaxis was a frequently addressed issue – both related to application, indication and duration. Avoiding antibiotic treatment of asymptomatic bacteriuria and upper respiratory tract infections were central topics of all countries. Conclusion: AMS is an important strategy to fight increasing resistance and is frequently addressed by Choosing Wisely recommendations of different countries. Similar issues are considered important in the selected countries. [ABSTRACT FROM AUTHOR]

Background: Antimicrobial resistance (AMR) is a growing problem worldwide, with differences in regional resistance patterns partially driven by local variance in antibiotic stewardship. Trauma patients transferring from Mexico have more AMR than those injured in the United States; we hypothesized a similar pattern would be present for burn patients. Patients and Methods: The registry of an American Burn Association (ABA)-verified burn center was queried for all admissions for burn injury January 2015 through December 2019 with hospital length-of-stay (LOS) longer than seven days. Patients were divided into two groups based upon burn location: United States (USA) or Mexico (MEX). All bacterial infections were analyzed. Results: A total of 73 MEX and 826 USA patients were included. Patients had a similar mean age (40.4 years MEX vs. 42.2 USA) and gender distribution (69.6% male vs. 64.4%). The MEX patients had larger median percent total body surface area burned (%TBSA; 11.1% vs. 4.3%; p ≤ 0.001) and longer hospital LOS (18.0 vs. 13.0 days; p = 0.028). The MEX patients more often had respiratory infections (16.4% vs. 7.4%; p = 0.046), whereas rates of other infections were similar. The MEX patients had higher rates of any resistant organism (47.2% of organisms MEX vs. 28.1% USA; p = 0.013), and were more likely to have resistant infections on univariable analysis; however, on multivariable analysis country of burn was no longer significant. Conclusions: Antimicrobial resistance is more common in burn patients initially burned in Mexico than those burned in the United States, but location was not a predictor of resistance compared to other traditional burn-related factors. Continuing to monitor for AMR regardless of country of burn remains critical. [ABSTRACT FROM AUTHOR]

Purpose Surgical patients with a penicillin allergy label (PAL) are less likely to receive β-lactams for surgical site infection (SSI) prophylaxis and more likely to receive second-line antibiotics, which may increase the risk of SSI, drug toxicities, and associated costs. We assessed the impact of implementing a pharmacist-led quality improvement project to increase the use of cefazolin as a first-line agent in this population. Summary After implementation of a pilot project in December 2021, all patients with a PAL and orders for preoperative antibiotics were risk stratified into high- or low-risk categories by a pharmacist. For the low-risk group, cefazolin was recommended. For the high-risk group, cefazolin was avoided and a second-line agent was administered. Our analysis compared 422 preintervention patients (August 15 to November 15, 2021) to 492 postintervention patients (December 15 to March 15, 2022). During the postintervention period, β-lactam usage increased (from 12.6% to 37.8%, P < 0.001), while usage of vancomycin (45.5% vs 29.5%, P < 0.001) and other second-line antibiotics (87.4% vs 62.2%, P < 0.001) declined. There were no adverse reactions reported in the preintervention cohort, with 2 potential adverse reactions reported after the intervention (0% vs 0.4%, P = 0.190). Medication costs based on claims data were 50% to 80% lower for patients receiving cefazolin. Conclusion In our cohort, a pharmacy-led antibiotic selection algorithm for patients with a PAL receiving perioperative antimicrobial prophylaxis resulted in increased use of β-lactam antibiotics, decreased use of second-line antibiotics, and decreased costs without a significant change in the incidence of adverse reactions.

The article discusses research which evaluated trends in antibiotic dispensations and treatment of acute sinusitis between 2003 to 2020 using the MarketScan Commercial Claims and Encounters Database. The study assessed the impact of the Infectious Diseases society of America's guidelines on antibiotic selection and prescribing practices. Results revealed changes in the proportion of children dispensed with amoxicillin, azithromycin, cefdinir and amoxicillin-clavulanate.

Objective: Both the United Nations and the World Health Organization have identified antimicrobial resistance as a significant threat to global health. The Centers for Disease Control and Prevention identified five pediatric respiratory conditions as requiring particular scrutiny in terms of antibiotic stewardship. This study sought to identify strategies used by experienced naturopathic practitioners to treat acute respiratory infections in children. The authors theorize that naturopathic strategies safely fill the gap between watchful waiting and antibiotic prescription, thus reducing the use of antibiotics. Methods: Naturopathic practitioners in Canada, the United States, and Australia with a minimum of 5 years of experience in clinical naturopathic care of children were recruited for a modified Delphi study. A 14-person panel of practitioners was selected to complete a series of four iterative surveys assessing agreement to statements in five domains of knowledge/attitudes, assessment/diagnosis, management, monitoring, and education. Items were deemed to have reached consensus if they reached a predetermined threshold of 70% agreement, or failed to reach a threshold of 40% agreement. Items between these boundaries were modified and retested until either consensus was reached or the four surveys had been completed. Results: Results yielded a large degree of agreement on core naturopathic approaches to the management of acute pediatric respiratory infections, especially lifestyle strategies, including adequate rest and dietary recommendations. The use of vitamins C and D was strongly supported, as were herbs, particularly echinacea and elderberry. Some hydrotherapy and topical applications specific to the individual focus on infection also reached consensus. Results suggested that most respondents, even if they have the authority to prescribe antibiotics, rarely deem it necessary to do so. Conclusion: Findings of this study provide (1) clarity on the role of naturopathic doctors in the management of pediatric health concerns and the stewardship of antibiotics; and (2) initial guidance to less experienced naturopathic practitioners. The findings also identify key priorities for research into the safety and effectiveness of naturopathic interventions to reduce the unnecessary prescribing of antibiotics. [ABSTRACT FROM AUTHOR]

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.

Background Empiric antibiotic use among hospitalized adults in the United States (US) is largely undescribed. Identifying factors associated with broad-spectrum empiric therapy may inform antibiotic stewardship interventions and facilitate benchmarking. Methods We performed a retrospective cohort study of adults discharged in 2019 from 928 hospitals in the Premier Healthcare Database. "Empiric" gram-negative antibiotics were defined by administration before day 3 of hospitalization. Multivariable logistic regression models with random effects by hospital were used to evaluate associations between patient and hospital characteristics and empiric receipt of broad-spectrum, compared to narrow-spectrum, gram-negative antibiotics. Results Of 8 017 740 hospitalized adults, 2 928 657 (37%) received empiric gram-negative antibiotics. Among 1 781 306 who received broad-spectrum therapy, 30% did not have a common infectious syndrome present on admission (pneumonia, urinary tract infection, sepsis, or bacteremia), surgery, or an intensive care unit stay in the empiric window. Holding other factors constant, males were 22% more likely (adjusted odds ratio [aOR], 1.22 [95% confidence interval, 1.22–1.23]), and all non-White racial groups 6%–13% less likely (aOR range, 0.87–0.94), to receive broad-spectrum therapy. There were significant prescribing differences by region, with the highest adjusted odds of broad-spectrum therapy in the US West South Central division. Even after model adjustment, there remained substantial interhospital variability: Among patients receiving empiric therapy, the probability of receiving broad-spectrum antibiotics varied as much as 34+ percentage points due solely to the admitting hospital (95% interval of probabilities: 43%–77%). Conclusions Empiric gram-negative antibiotic use is highly variable across US regions, and there is high, unexplained interhospital variability. Sex and racial disparities in the receipt of broad-spectrum therapy warrant further investigation. [ABSTRACT FROM AUTHOR]

Background: Antimicrobial stewardship in the community is essential as most antibiotic prescribing occurs in the outpatient setting. Pharmacists are recognized as co-leaders for implementing efforts to improve antimicrobial use. Objectives: the purpose of this study is to evaluate current antimicrobial stewardship practices in community pharmacies across the United States and identify perceptions and challenges faced by community pharmacists. Methods: a survey based on the Center of Disease Control and Prevention (CDC) Core Elements of Outpatient Antibiotic Stewardship was created and distributed. Results: Sixty-one community pharmacists participated in the survey. The majority of pharmacists practiced in chain pharmacies. Based on the responses, a minority of pharmacies met the requirements of the CDC core elements: commitment (27.9%), action (24.6%), tracking and reporting (14.8%), and education and expertise (23% for providing pharmacist resources and 9.8% for providing patient resources). Regarding perception, 67.9% felt antimicrobial stewardship is important in the community and would participate in antimicrobial stewardship activities if the opportunity was provided (88.5%). Challenges faced by community pharmacists include the lack of time, staff, training, and technology support; pushback from prescribers and patients; and the lack of leadership, financial incentives, funding, and legal requirements. Conclusions: many challenges exist in community pharmacies inhibiting the full potential of pharmacists in implementing antimicrobial stewardship. [ABSTRACT FROM AUTHOR]

Antibiotic resistance is a major public health concern driven by antibiotic overuse. Antibiotic stewardship programs are often limited to clinical settings and do little to address non-prescription antibiotic use in community settings. This study investigates the association between non-prescription antibiotic use and healthcare system distrust in the United States and Mexico. An online survey was deployed in the United States and Mexico with enhanced sampling through in-person recruiting in the border region. Non-prescription antibiotic use was defined as having bought or borrowed non-prescription oral or injectable antibiotics within the last 3 years. The survey included a previously validated 10-item scale to measure healthcare system distrust. Logistic regression was used to model the use of non-prescription antibiotics by the level of healthcare system distrust, adjusted for demographic characteristics and antibiotic knowledge. In total, 568 survey participants were included in the analysis, 48.6% of whom had used non-prescription oral or injectable antibiotics in the last 3 years. In the fully adjusted regression model, the odds of using non-prescription antibiotics were 3.2 (95% CI: 1.8, 6.1) times higher for those in the highest distrust quartile versus the lowest. These findings underscore the importance of community-based antibiotic stewardship and suggest that these programs are particularly critical for communities with high levels of healthcare system distrust.

Introduction: The latest vancomycin therapeutic drug monitoring guidelines for serious MRSA infections have made a pivotal change in dosing, switching from targeting trough levels to AUC dosing. Because of these new recommendations, antimicrobial stewardship programs across the country are tasked with implementing AUC based dosing. Objectives: To assess plans for institutional adoption of vancomycin AUC dosing programs and perceptions of currently used programs in hospitals across the US. Methods: An electronic survey was distributed to members of the American College of Clinical Pharmacy IDprn Listserv and American Society of Health-System Pharmacists between May and June 2020 to assess current institutional vancomycin dosing. Institutional program use and multiple software user parameters were analyzed using descriptive statistics. Results: Two hundred two pharmacists responded to the survey with the majority practicing in institutions with 251-500 beds. Most respondents have yet to implement AUC dosing (142/202, 70.3%) with many of them planning to do so in the next year (81/142, 57.0%). Of those that already implemented AUC dosing programs, purchased Bayesian software (23/60, 38.3%) and homemade software (21/60, 35.0%) were the 2 methods most frequently utilized. Purchased Bayesian software users were more likely to recommend their software to other institutions and ranked user friendliness higher compared to non-purchased software. Conclusion: Most respondents have not made the switch to vancomycin AUC dosing, but there is a growing interest with many institutions looking to adopt a program within the next year.

Given the complexity of antimicrobial resistance and the dire implications of misusing antimicrobials, it is imperative to identify accurate and meaningful ways to understand and communicate the realities, challenges, and opportunities associated with antimicrobial utilization and measurement in all sectors, including in animal agriculture. The objectives of this article are to (i) describe how antimicrobials are regulated and used in US animal agriculture and (ii) highlight realities, challenges, and opportunities to foster multidisciplinary understanding of the common goal of responsible antimicrobial use. Recognition of the realities of medicine, practice, and policy in the agricultural setting is critical to identify realistic opportunities for improvement and collaboration. [ABSTRACT FROM AUTHOR]

The third opium war may have already started, not only due to illicit opioid trafficking from the Golden Crescent and Golden Triangle on the international front but also through indiscriminate opioid prescription and opioid diversion at home. Opioid use disorder (OUD), among unintentional injuries, has become one of the top 4 causes of death in the United States (U.S.). An OUD is defined as a problematic pattern of opioid use resulting in clinically significant impairment or distress, consisting of 2 or more of 11 problems within 1 year, as described by the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition. Observation of aberrant behaviors of OUD is also helpful for overworked clinicians. For the prevention of OUD, the Opioid Risk Tool and the Current Opioid Misuse Measure are appropriate screening tests before and during opioid administration, respectively. Treatment of OUD consists of 3 opioid-based U.S. Food and Drug Administration-approved medications, including methadone, buprenorphine, and naltrexone, and non-opioid-based symptomatic medications for reducing opioid withdrawal syndromes, such as a2 agonists, ß-blockers, antidiarrheals, antiemetics, non-steroidal anti-inflammatory drugs, and benzodiazepines. There are at least 6 recommendable guidelines and essential terms related to OUD. Opioid stewardship programs are now critical to promoting appropriate use of opioid medications, improving patient outcomes, and reducing misuse of opioids, influenced by the successful implementation of antimicrobial stewardship programs. Despite the lack of previous motivation, now is the critical time for trying to reduce the risk of OUD. [ABSTRACT FROM AUTHOR]

The burden of infections in acute care surgery (ACS) is huge. Surgical emergencies alone account for three million admissions per year in the United States (US) with estimated financial costs of USD 28 billion per year. Acute care facilities and ACS patients represent boost sanctuaries for the emergence, development and transmission of infections and multi-resistant organisms. According to the World Health Organization, healthcare-associated infections affected around 4 million cases in Europe and 1.7 million in the US alone in 2011 with 39,000 and 99,000 directly attributable deaths, respectively. In this scenario, antimicrobial resistance arose as a public-health emergency that worsens patients' morbidity and mortality and increases healthcare costs. The optimal patient care requires the application of comprehensive evidence-based policies and strategies aiming at minimizing the impact of healthcare associated infections and antimicrobial resistance, while optimizing the treatment of intra-abdominal infections. The present review provides a snapshot of two hot topics, such as antimicrobial resistance and systemic inflammatory response, and three milestones of infection management, such as source control, infection prevention, and control and antimicrobial stewardship.

Background: Antibiotic resistance is a leading global public health threat. Nurses are well positioned to optimize antibiotic use via targeted antibiotic stewardship (AS) nursing practices. However, standardized AS education for nurses is lacking. The objective of this study was to evaluate the effect of an online AS for nurses continuing education program on nurses' antibiotic resistance, antibiotic, and AS knowledge and their intent to integrate AS into their clinical practice. Method: A quasi-experiential pretest–posttest design was used with a convenience sample of nurses at a U.S. academic medical center. Focus groups were conducted with those completing the program. Results: Forty-seven of 100 eligible nurses completed the program and the pre- and posttest surveys. Participation resulted in statistically significant increases (p <.05) in antibiotic resistance, antibiotic, and AS knowledge, confidence, and perceptions related to the role of nursing in AS. Focus group participants had multiple recommendations for ways to integrate AS in daily nursing practice. Conclusion: Completing a comprehensive AS nursing continuing education program could prove instrumental to motivating nurses to adopt AS nursing practices.

Objective: To determine the prevalence of C-reactive protein (CRP) use in early-onset sepsis (EOS) evaluations in neonatal intensive care units (NICUs) across the US over time and to determine the association between CRP use and antibiotic use., Study Design: A retrospective cohort study of NICUs contributing data to Premier Healthcare Database from 2009 through 2021. EOS evaluation was defined as a blood culture charge ≤ 3 days after birth. CRP use for each NICU was calculated as the proportion of infants with a CRP test obtained ≤ 3 days after birth among those undergoing an EOS evaluation and categorized as, low (<25%); medium-low (25 to < 50%), medium-high (50 to < 75%), and high (≥75%). Outcomes included antibiotic use and mortality ≤ 7 days after birth., Results: Among 572 NICUs, CRP use varied widely and was associated with time. The proportion of NICUs with high CRP use decreased from 2009 to 2021 (24.7% vs 17.4%, P < .001), and those with low CRP use increased (47.9% vs 64.8%, P < .001). Compared with low-use NICUs, high-use NICUs more frequently continued antibiotics > 3 days (10% vs 25%, P < .001). This association persisted in multivariable-adjusted regression analyses (adjusted risk ratio 1.95, 95%CI 1.54, 2.48). Risk of mortality was not different in high-use NICUs (adjusted risk difference -0.02%, 95%CI -0.04%, 0.0008%)., Conclusions: CRP use in EOS evaluations varied widely across NICUs. High CRP use was associated with prolonged antibiotic therapy but not mortality ≤ 7 days after birth. Reducing routine CRP use in EOS evaluations may be a target for neonatal antibiotic stewardship efforts., Competing Interests: Declaration of Competing Interest This work was supported by Clinical Futures, a Research Institute Center of Emphasis at the Children's Hospital of Philadelphia.

Background: Antibiotic overuse at hospital discharge is common, but there is no metric to evaluate hospital performance at this transition of care. We built a risk-adjusted metric for comparing hospitals on their overall post-discharge antibiotic use., Methods: This was a retrospective study across all acute-care admissions within the Veterans Health Administration during 2018-2021. For patients discharged to home, we collected data on antibiotics and relevant covariates. We built a zero-inflated, negative, binomial mixed model with 2 random intercepts for each hospital to predict post-discharge antibiotic exposure and length of therapy (LOT). Data were split into training and testing sets to evaluate model performance using absolute error. Hospital performance was determined by the predicted random intercepts., Results: 1 804 300 patient-admissions across 129 hospitals were included. Antibiotics were prescribed to 41.5% while hospitalized and 19.5% at discharge. Median LOT among those prescribed post-discharge antibiotics was 7 (IQR, 4-10) days. The predictive model detected post-discharge antibiotic use with fidelity, including accurate identification of any exposure (area under the precision-recall curve = 0.97) and reliable prediction of post-discharge LOT (mean absolute error = 1.48). Based on this model, 39 (30.2%) hospitals prescribed antibiotics less often than expected at discharge and used shorter LOT than expected. Twenty-eight (21.7%) hospitals prescribed antibiotics more often at discharge and used longer LOT., Conclusions: A model using electronically available data was able to predict antibiotic use prescribed at hospital discharge and showed that some hospitals were more successful in reducing antibiotic overuse at this transition of care. This metric may help hospitals identify opportunities for improved antibiotic stewardship at discharge., Competing Interests: Potential conflicts of interest. The authors: No reported conflicts of interest. All authors have submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest., (© The Author(s) 2024.

Objective: To understand antimicrobial stewardship (AS) and infection prevention and control (IPC) activities in veterinary schools., Methods: An online survey was completed by representatives from American Association of Veterinary Medical Colleges-accredited veterinary schools in the US and Caribbean prior to attending the Inaugural Small Animal Antimicrobial Stewardship Workshop for US Veterinary Schools. Responses were examined to identify patterns among AS and IPC activities and adherence to the AVMA core principles., Results: Half (12 of 24) of the surveyed schools had an AS committee and most (79% [19 of 24]) had an IPC committee. Lack of dedicated staff time was a common barrier to AS (88% [21 of 24]) and IPC (75% [18 of 24]) reported by schools both with and without AS and IPC committees. Eleven of 24 schools (46%) reported performing at least 1 activity focused on each of the AVMA's 5 core principles of AS. Although 79% (19 of 24) of schools incorporate AS into preclinical curricula, training of clinical faculty (17% [4 of 24]), veterinary technicians and support staff (21% [5 of 24]), and house officers (42% [10 of 24]) is less common, despite these individuals engaging in teaching clinical-year veterinary students., Conclusions: Veterinary schools varied in established AS education and AS and IPC practices, though financial and human resources were a common barrier., Clinical Relevance: A collaborative and cohesive approach to AS and IPC among schools to create sustainable frameworks for practice improvement will help combat the global threat of antimicrobial resistance. This is a critical action for settings where future veterinarians are trained.

Antifungal-resistant dermatophyte infections have recently emerged as a global public health concern. A survey of US infectious diseases specialists found that only 65% had heard of this issue and just 39% knew how to obtain testing to determine resistance. Increased clinician awareness and access to testing for antifungal-resistant dermatophytosis are needed.
