Background: Inappropriate antimicrobial use continues to threaten modern medicine. The ongoing pandemic likely exacerbated this problem because COVID-19 presents similarly to bacterial pneumonia, confusion exists regarding treatment guidelines, and testing turnaround times (TATs) are slow. Our primary object was to quantify antimicrobial use changes during the pandemic to rates before the crisis. A subanalysis within the COVID-19 cohort was completed based on SARS-CoV-2 status. Methods: The pre–COVID-19 period was January–May 2019 and the COVID-19 period was January–May 2020. Subanalyses were used to explore differences in antibiotics use between persons not under investigation (non-PUIs), SARS-CoV-2–negative PUIs, and SARS-CoV-2–positive PUIs. Non-PUI patients were those without respiratory symptoms and/or fever. The χ2 and Wilcoxon signed rank-sum tests were used for analysis. Results: During the 2019 and 2020 study periods, 7,909 and 7,283 patients received >1 antimicrobial, respectively (Figure 1). Overall, antibiotic therapy per 1,000 patient days increased from 633.1 before COVID-19 to 678.5 during COVID-19, a 7.2% increase (Table 1). Notably, broad-spectrum respiratory antibiotics demonstrated a significant increase between pre–COVID-19 and COVID-19 cohorts (p < 0.001). Of the 7,283 patients within the COVID-19 cohort, 34.7% (n = 2,532) were PUI and 13.8% (n = 1,002) of these patients tested SARS-CoV-2 positive. Again, broad-spectrum respiratory antibiotics use was significantly increased for COVID-19 patients (p < 0.001). Of note, the proportion of patients receiving respiratory antibiotics steadily decreased over time (R2 = 0.99). Conclusions: There was a significant increase in antibiotic use during the COVID-19 pandemic. Encouragingly, antimicrobial use decreased over time, likely due to (1) faster TATs, (2) real-time education to clinicians and subsequent de-escalation of unnecessary antimicrobials, and (3) development of treatment guidelines as new research emerged.Funding: NoDisclosures: None

Abstract Background About 30–50% of inpatient antimicrobial therapy is sub-optimal. Health care facilities have utilized various antimicrobial stewardship (AS) strategies to optimize appropriate antimicrobial use, improve health outcomes, and promote patient safety. However, little evidence exists to assess relationships between AS strategies and antimicrobial use. This study examined the impact of changes in AS strategies on antimicrobial use over time. Methods This study used data from the Veterans Affairs (VA) Healthcare Analysis & Informatics Group (HAIG) AS survey, administered at 130 VA facilities in 2012 and 2015, and antimicrobial utilization from VA Corporate Data Warehouse. Four AS strategies were examined: having an AS team, feedback mechanism on antimicrobial use, infectious diseases (ID) attending physicians, and clinical pharmacist on wards. Change in AS strategies were computed by taking the difference in the presence of a given strategy in a facility between 2012–2015. The outcome was the difference between antimicrobial use per 1000 patient days in 2012–2013 and 2015–2016. Employing multiple regression analysis, changes in antimicrobial use was estimated as a function of changes in AS strategies, controlling for ID human resources in and organizational complexity. Results Of the 4 strategies, only change in availability of AS teams had an impact on antimicrobial use. Compared to facilities with no AS teams at both time points, antibiotic use decreased by 63.9 uses per 1000 patient days in facilities that did not have a AS team in 2012 but implemented one in 2015 (p=0.0183). Facilities that had an AS team at both time points decreased use by 62.2 per 1000 patient days (p=0.0324). Conclusion The findings showed that AS teams reduced inpatient antibiotic use over time. While changes in having feedback on antimicrobial use and clinical pharmacist on wards showed reduced antimicrobial use between 2012–2015, the differences were not statistically significant. These strategies may already be a part of a comprehensive AS program and employed by AS teams. In further development of stewardship programs within healthcare organizations, the association between AS teams and antibiotic use should inform program design and implementation.

Background: Antimicrobial decision making in the ICU is challenging. Injudicious use of antimicrobials contributes to the development of resistant pathogens and drug-related adverse events. However, inadequate antimicrobial therapy is associated with mortality in critically ill patients. Antimicrobial stewardship programs are increasingly being implemented to improve prescribing. Methods: This prospective study was conducted over 11 months, during which the pharmacist used a standardized survey form to collect data on antibiotic use. Evaluation of antimicrobial use and stewardship practices in a 12-bed polytrauma ICU and a 20-bed neurosurgery ICU of the 248-bed AIIMS Trauma Center in Delhi, India. Antimicrobial consumption was measured using WHO-recommended defined daily dose (DDD) of given antimicrobials and days of therapy (DOT). Results: Antibiotics were ranked by frequency of use over the 11-month period based on empirical therapy and culture-based therapy. The 11-month DDD and DOT averages when empiric antibiotics were used were 532 of 1,000 patient days and 484 per 1,000 patient days, respectively (Figure 1). When cultures were available, DDD was 486 per 1,000 patient days and DOT was 442 per 1,000 patient days (Figure). Conclusions: The quantity and frequency of antibiotics used in the ICUs allowed the AMSP to identify areas to optimize antibiotic use such as educational initiatives, early specimen collection, and audit and feedback opportunities.Funding: NoDisclosures: None

 Objective: The objective of the study was to evaluate antimicrobial prescription pattern in outpatient departments.Method: This was a prospective, cross-sectional and observational study over 12 weeks total 400 prescriptions of either gender and age; containing antimicrobial agents (AMAs) were analyzed for demographic data and the WHO prescribing indicators.Results: Most of prescription were given to men (n=262). The most common group of AMA used was Cephalosporins (n=141, 35.25%); of which Ceftriaxone was most commonly prescribed (n=73, 18.25%). 10 AMAs were from the WHO essential medicine list AMAs. Men outnumbered women in prescribing antibiotics (n=262 vs. 138). Most of AMAs receivers were between 26 and 35 years (n=128, 32%). Amoxicillin+Clavulanic acid fixed-dose combination was most common (n=84, 21%). Most of the prescriptions were containing four drugs per prescriptions (n=130, 32.5%). Only 10% of the prescription was given by generic name and rest 90% were given by brand name. Oral dosage form of AMAs was predominant (n=340, 85%). Vitamins and supplement were most common comedication received by patients.Conclusion: Antibiotic use was found to be reasonable and rational in most of the cases. However, still, prescribers should improve prescribing practices and make it more rational.

Abstract Background To identify areas for improved antibiotic use, we developed and pilot-tested visualization tools to quantify antibiotic use at 8 VA facilities. These tools allow a facility to review its patterns of total use, and use by antibiotic class, compared with patterns of use at VA facilities with similar (or user-selected) complexity levels. Methods Antibiotic stewards from 8 VA facilities participated in iterative report development and implementation, with the final product consisting of two components: an interactive web-based antibiotic dashboard and a standardized antibiotic usage report updated at user-selected intervals. Stewards also participated in monthly learning collaboratives. The percent change in average monthly antimicrobial use (all antibiotics; anti-methicillin-resistant S. aureus agents (anti-MRSA); and broad-spectrum agents predominantly used for hospital-onset/multi-drug-resistant organisms (anti-MDRO)) was analyzed using a pre-post (January 2014–January 2016 vs. July 2016–January 2018) with un-involved controls (all other inpatient VA facilities, n = 132) design modeled using Generalized Estimation Equations segmented regression. Results Intervention sites had a 2.1% decrease (95% CI = [−5.7%,1.6%]) in all antibiotic use pre-post-intervention, vs. a 2.5% increase (95% CI = [0.8%, 4.1%]) in nonintervention sites (P = 0.025 for difference). Anti-MRSA antibiotic use decreased 11.3% (95% CI = [−16.0%,−6.3%]) at intervention sites vs. a 6.6% decrease (95% CI=[−9.1%, −3.9%]) at nonintervention sites (P = 0.092 for difference). Anti-MDRO antibiotic use decreased 3.4% (95% CI = [−8.2%,1.7%]) at intervention sites vs. a 3.6% increase (95% CI = [0.8%,6.5%]) at nonintervention sites (P = 0.018 for difference) (Figure 1). Examples of graphs include overall antibacterial use (Figure 2), and usage of broad-spectrum Gram-negative therapy (Figure 3) in intensive care units. Conclusion The use of data visualization tools use and participation in monthly learning collaboratives by antimicrobial stewards in a pilot implementation project at eight VA facilities was associated with decreases in antimicrobial use relative to uninvolved sites.

Background: Unnecessary antimicrobial use is an emerging problem throughout the world. To design future interventions to ensure rational antimicrobial use and decrease the risk of antimicrobial resistance, physician's knowledge and prescribing practices of antimicrobials should be assessed. Therefore, the main objective of this study is to investigate the physician's knowledge along with their prescribing patterns of antimicrobials in their health care system.Methods: The present qualitative study was conducted in a tertiary care public hospital located at Penang island, situated in Northwest of Malaysia. A total of 12 semi-structured, face to face interviews were conducted with purposive sampling technique. Physicians recruited had different specialties. All interviews were audio recorded, then transcribed into English language and analyze by thematic content analysis.Results: Four major themes were identified: (1) prescribing patterns of physicians regarding antimicrobials; (2) physician's knowledge about antimicrobials; (3) antimicrobial resistance; (4) satisfaction with management of infections. Physicians believed in regular educational activities and updates about the latest antimicrobial guidelines may change the prescribing behavior of physicians to optimize the use of antimicrobials. This may lead to decrease in burden of antimicrobial resistance in their health care system. Physicians emphasized that stricter rules and regular monitoring of antimicrobial use should be implemented to overcome the main challenges of antimicrobial resistance.Conclusion: Different factors were identified to assist optimized use of antimicrobials and decrease the risk of antimicrobial resistance. The present study helps to design targeted future interventions to ensure rational antimicrobial use and decrease the impact of antimicrobial resistance in Malaysia.

Abstract Objectives Understanding the current state of antibiotic treatment guidelines and prescribing practices for bacterial enteric infections is critical to inform antibiotic stewardship initiatives. This study aims to add to the current understanding through three objectives: (i) to identify and summarize published treatment guidelines for bacterial enteric infections; (ii) to describe observed antibiotic prescribing practices for bacterial enteric infections across three sentinel sites in Canada; and (iii) to assess concordance between observed antibiotic prescribing and treatment guidelines. Methods An environmental scan of treatment guidelines for bacterial enteric infections was conducted and recommendations were collated. A descriptive analysis of cases of bacterial enteric illnesses captured in FoodNet Canada’s sentinel site surveillance system between 2010 and 2018 was performed. Antibiotic-use data were self-reported by cases via an enhanced questionnaire. Results Ten treatment guidelines were identified in the environmental scan. There was substantial variation between guidelines for both when to prescribe antibiotics and which antibiotics were recommended. Of the 5877 cases of laboratory-confirmed bacterial enteric illness in the three sites, 49% of cases reported having received an antibiotic prescription. Of particular significance was the finding that 21% of verotoxigenic Escherichia coli cases received a prescription. Of the 17 antibiotics recommended in the guidelines, 14 were used in practice. In addition to these, 18 other antibiotics not included in any of the guidelines reviewed were also prescribed. Conclusions Our study suggests that a substantial proportion of enteric bacterial infections in Canada are prescribed antibiotics. These findings highlight the need to standardize treatment guidelines for enteric illnesses and could be used to inform future stewardship programme development.

Abstract Background Inappropriate antibiotic use is a global health concern as it increases antibiotic resistance. Antibiotics are not routinely recommended for treating acute gastroenteritis, non-typhoidal salmonella and campylobacter infections. We investigated adherence to these recommendations in primary care. Methods We used a large electronic database of primary care records to identify presentations for acute gastroenteritis, non-typhoidal salmonella and campylobacter infections and antibiotic prescribing from 1st Jan 2013 to 31 December 2018. We estimated the proportions of cases prescribed antibiotics according to various characteristics and examined the antibiotics prescribed. Results A total of 86998, 1106, and 1952 participants were identified with acute gastroenteritis, non-typhoidal salmonella, and campylobacter infections and correspondingly 10% (8720/86998), 40% (437/1106), and 57% (1118/1952) of these cases were prescribed antibiotics in the period up to 5 days post-diagnosis. Patients residing in outer regional/remote areas and those from Northern Territory and Queensland were more likely to be prescribed antibiotics than those residing in major cities and those from other states (p &lt; =0.04). No dominant antibiotic class was prescribed for acute gastroenteritis. Quinolones (28.6%) and macrolides (27.0%) were the most frequently prescribed antibiotics for non-typhoidal salmonella, and macrolides (69%) were the predominant antibiotics prescribed for campylobacter. Conclusion The high proportion of antibiotics dispensed in the general population with acute gastroenteritis, non-typhoidal salmonella and campylobacter infections suggests that antimicrobial stewardship needs to include better education and awareness around treatment guidelines for such infections. Key messages Antibiotics use was common for Australian population with acute gastroenteritis, particularly those with non-typhoidal salmonella and campylobacter infections.

Abstract Background Most skin and soft tissue infections (SSTIs) are managed in the outpatient setting, but data are lacking on treatment patterns outside the emergency department (ED). Available data suggest that there is poor adherence to SSTI treatment guidelines. Methods We conducted a retrospective cohort study of Veterans diagnosed with SSTIs in the ED or outpatient clinics from 1 January 2005 through 30 June 2018. The incidence of SSTIs over time was modeled using Poisson regression using robust standard errors. Antibiotic selection and incision and drainage (I&D) were described and compared between ambulatory settings. Anti–methicillin-resistant Staphylococcus aureus (MRSA) antibiotic use was compared to SSTI treatment guidelines. Results There were 1 740 992 incident SSTIs in 1 156 725 patients during the study period. The incidence of SSTIs significantly decreased from 4.58 per 1000 patient-years in 2005 to 3.27 per 1000 patient-years in 2018 (P &lt; .001). There were lower rates of β-lactam prescribing (32.5% vs 51.7%) in the ED compared to primary care (PC), and higher rates of anti-MRSA therapy (51.4% vs 35.1%) in the ED compared to PC. The I&D rate in the ED was 8.1% compared to 2.6% in PC. Antibiotic regimens without MRSA activity were prescribed in 24.9% of purulent SSTIs. Anti-MRSA antibiotics were prescribed in 40.1% of nonpurulent SSTIs. Conclusions We found a decrease in the incidence of SSTIs in the outpatient setting over time. Treatment of SSTIs varied depending on the presenting ambulatory location. There is poor adherence to guidelines in regard to use of anti-MRSA therapies. Further study is needed to understand the impact of guideline nonadherence on patient outcomes.

Objectives.To evaluate (1) the framework of the 12 Steps to Prevent Antimicrobial Resistance Among Hospitalized Adults that is part of the Centers for Disease Control and Prevention (CDC) Campaign to Prevent Antimicrobial Resistance in Healthcare Settings, with regard to steps addressing antimicrobial use; and (2) methods of feedback to clinicians regarding antimicrobial use after postprescription review.Design.Prospective intervention to identify and modify inappropriate antimicrobial therapy.Setting.A 1,000-bed, tertiary care teaching hospital.Patients.Inpatients in selected medicine and surgery units receiving broad-spectrum antimicrobials for 48-72 hours.Interventions.We created a computer-based clinical-event detection system that automatically identified inpatients taking broad-spectrum and “reserve” antimicrobials for 48-72 hours. Although prior approval was required for initial administration of broad-spectrum and reserve antimicrobials, once approval was obtained, therapy with the antimicrobials could be continued indefinitely at the discretion of the treating clinician. Therapy that was ongoing at 48-72 hours was reviewed by an infectious diseases pharmacist or physician, and when indicated feedback was provided to clinicians to modify or discontinue therapy. Feedback was provided via a direct telephone call, a note on the front of the medical record, or text message sent to the clinician's pager. The acceptance rate of feedback was recorded and recommendations were categorized according to the 12 steps recommended by the CDC.Results.Interventions were recommended for 334 (30%) of 1,104 courses of antimicrobial therapy reviewed. A total of 87% of interventions fit into one of the CDC's 12 steps of prevention: 39% into step 3 (“target the pathogen”), 1% into step 4 (“access experts”), 3% into steps 7 and 8 (“treat infection, not colonization or contamination”), 18% into step 9 (“say ‘no’ to vancomycin”), and 26% into step 10 (“stop treatment when no infection”). The rate of compliance with recommendations to improve antimicrobial use was 72%. No differences in compliance were seen with the different methods of feedback.Conclusions.Nearly one-third of antimicrobial courses did not follow the CDC's recommended 12 steps for prevention of antimicrobial resistance. Clinicians demonstrated high compliance with following suggestions made after postprescription review, suggesting that it is a useful approach to decreasing and improving antimicrobial use among inpatients.

Abstract Background Provision of provider-specific outpatient antibiotic prescribing data has resulted in significant decreases in antibiotic use. We describe the development of reports of inpatient antibiotic prescribing by hospitalists attending on acute medical wards in VA medical facilities. Methods We created algorithms for determining the attending physician responsible for patient days present (DP), by considering changes of service (e.g., prior to admission from the emergency department) and transfers between services or physicians. Each antibiotic dose was assigned to a single attending, ward location, and service according to denominator assignment. Antibiotic use was grouped into Centers for Disease Control and Prevention drug categories and expressed as antibiotic days of therapy (DOT) per 1000 DP. Data were obtained from the VA Corporate Data Warehouse. Algorithms were iteratively refined based on reviews of medical records from three VA medical centers and applied to acute care patients at a single site for 2018-2020. Results In 2018-2020, 294 attendings oversaw acute inpatient care for &gt;= 14 DP. 129 attendings with &gt;= 300 DP oversaw 88.0% of all patient care and prescribed 87.6% of all antibiotics (480 DOT/1000 DP, IQR 375-559), 90.1% of broad-spectrum therapy for hospital-onset infections (55 DOT/1000 DP, IQR 31-72) and 88.3% of resistant Gram-positive therapy (70 DOT/1000 DP, IQR 39-89) in inpatient wards. The distribution of antibiotic use for acute care ward patients amongst these 129 staff is shown in the following figure. Conclusion We developed algorithms to attribute antibiotic therapy to inpatient attendings that can be broadly applied in facilities with electronic medical records. As with outpatient prescribing, we found large variation across inpatient attendings in overall antibiotic use and broad-spectrum antibiotic use. In future work, we will obtain provider feedback of report usability and interpretability and assess whether distribution of these reports allows antibiotic stewards to favorably influence provider prescribing practices.
