1043. Love Thy Steward – Who Does Not Love Antimicrobial Stewardship?

Abstract Background The impact of antimicrobial stewardship programs (ASPs) depends on physician perception of antimicrobial stewardship and institutional antibiotic prescribing culture. At Rush University Medical Center (RUMC), we conducted an antimicrobial stewardship study targeting inpatient levofloxacin (FQ) use and assessed rates of implementation of recommendations (IORs) by general medicine (GM), vs. surgical services (SS) (general surgery, urology, orthopedics and neurosurgery), vs. transplant surgery-immunocompromised host (T-ICH) teams when made by either infectious disease pharmacists (IDPharmD) or infectious disease fellows (IDMDF). Methods Between August 13, 2018 and January 15, 2019 at RUMC, IDPharmDs reviewed 251 inpatients on FQ, and made ASP recommendations on 36 (14%) that were communicated via telephone. No scripted discussion or note was utilized. From January 15, 2019 to April 19, 2019, an IDMDF reviewed 207 inpatients on FQ, and made ASP recommendations on 47 (22%). IDMDF’s recommendations were communicated via a scripted discussion describing the role of ASP, highlighting the importance of optimizing FQ use due to toxicity, low rates of RUMC’s FQ susceptibilities and to decrease rates of resistance. Telephone recommendations were made to the primary team house staff or attending followed by a templated electronic note left in the medical chart. Rates of IORs were assessed during each period and by each group. Results In 20 out of 83 recommendations (24%), no antibiotic was indicated (Figure 1). GM teams had the highest overall (IDPharmD + IDMDF) IOR (76%), compared with 40% IOR for both SS and T-ICH groups. For all groups, the scripted IDMDF recommendations had higher IOR compared with the nonscripted IDPharmD recommendations (GM 89% vs. 61%; SS 50% vs. 29%; T-ICH 50% vs. 0%). Conclusion ASP interventions using scripted discussions and notes by an IDMDF were more effective than nonscripted IDPharmD interventions across all service lines. Both interventions were less successful with SS or T-ICH compared with GM services. These findings demonstrate the need for further research to understand the importance of scripted vs. nonscripted communication methods by pharmacists and ID physicians, and to develop alternative communication models for nongeneral medicine service providers.

The Impact

Abstract Background Treatment of asymptomatic bacteriuria (ASB) outside of pregnancy and urological procedures increases the risk of antibiotic resistance without improving outcomes. At Olive View-UCLA Medical Center (Sylmar, CA), the CDC U.S. Antibiotic Awareness Week (AAW) was utilized as a platform to promote antimicrobial stewardship (AS) for ASB. We evaluated the incidence of antibiotic treatment of ASB pre-AAW vs post-AAW, and the impact of AS education on future prescribing practices for ASB. Methods In this single-center retrospective observational study, AS education defining ASB vs urinary tract infection (UTI) was provided via visual aids distributed throughout the hospital during AAW from 11/18/2020 to 11/24/2020 (Figure 1). All positive urine cultures (Ucx) for adult inpatients were reviewed prior to AAW from 9/2020 to 11/2020 and after AAW from 12/2020 to 1/2021. Patients were excluded if they were unable to report UTI symptoms, pregnant, or undergoing urological procedure. The incidence of ASB treatment pre- and post-AAW was compared. A survey was sent to providers to compare the impact on antibiotic prescribing behavior for ASB pre- and post-AAW. Fisher’s exact and Chi-squared tests were used for statistical analysis. Figure 1. Antimicrobial Stewardship Education and Poster Distribution Results A total of 260 cases met study eligibility. In the pre-AAW group, 56 of 131 cases presented with ASB, of which 16 were treated with antibiotics (28.6%). In the post-AAW group, 55 of 129 cases presented with ASB, and 5 were treated with antibiotics (9.1%). Antibiotics were prescribed more often for patients with ASB in the pre-AAW group compared to those in the post-AAW group (p=0.014). Forty providers completed the survey, of which 97.5% had seen the visual aids, 70% had found the education "very” or “extremely" useful, and 43.6% reported they “always or sometimes” treated ASB pre-AAW vs 15% post-AAW (p< 0.01). Conclusion AS posters and education defining ASB significantly decreased the treatment of ASB. AAW education on ASB antimicrobial stewardship demonstrated a high value and shifted prescribing behavior to avoid antibiotic treatment of ASB. A similar approach to deliver provider education could serve as a valuable model to change provider AS practices for ASB. Disclosures All Authors: No reported disclosures

Abstract Background Measuring antimicrobial consumption data is a foundation of antimicrobial stewardship programs. There is data to support antimicrobial scorecard utilization to improve antibiotic use in the outpatient setting. There is a lack of data on the impact of an antimicrobial scorecard for hospitalists. Our objective was to improve antibiotic prescribing amongst the hospitalist service through the development of an antimicrobial scorecard. Methods Conducted in a 451-bed teaching hospital amongst 22 full time hospitalists. The antimicrobial scorecard for 2019 was distributed in two phases. In October 2019, baseline antibiotic prescribing data (January – September 2019) was distributed. In January 2020, a second scorecard was distributed (October – December 2019) to assess the impact of the scorecard. The scorecard distributed via e-mail to physicians included: Antibiotic days of therapy/1,000 patient care days (corrected for attending census), route of antibiotic prescribing (% intravenous (IV) vs % oral (PO)) and percentage of patients prescribed piperacillin-tazobactam (PT) for greater than 3 days. Hospitalists received their data in rank order amongst their peers. Along with the antimicrobial scorecard, recommendations from the antimicrobial stewardship team were included for hospitalists to improve their antibiotic prescribing for these initiatives. Hospitalists demographics (years of practice and gender) were collected. Descriptive statistics were utilized to analyze pre and post data. Results Sixteen (16) out of 22 (73%) hospitalists improved their antibiotic prescribing from pre- to post-scorecard (χ 2(1)=3.68, p = 0.055). The median antibiotic days of therapy/1,000 patient care days decreased from 661 pre-scorecard to 618 post-scorecard (p = 0.043). The median PT use greater than 3 days also decreased significantly, from 18% pre-scorecard to 11% post-scorecard (p = 0.0025). There was no change in % of IV antibiotic prescribing and no correlation between years of experience or gender to antibiotic prescribing. Conclusion Providing antimicrobial scorecards to our hospitalist service resulted in a significant decrease in antibiotic days of therapy/1,000 patient care days and PT prescribing beyond 3 days.

The Impact

Abstract Background When considering antimicrobial stewardship (AMS) interventions, pediatrics is an important and often overlooked group. By 5 years of age, 97% of New Zealand (NZ) children have received antibiotics (median 8 antibiotic courses/child). Prescribing is complex due to age and weight-based adjustments, unpalatable oral preparations and inappropriate allergy labeling. Our tertiary Children’s Hospital has >250 web-based nationally utilized guidelines, 15% including antimicrobials. A point prevalence audit showed only 63% guideline adherence for inpatient antimicrobial prescriptions. We designed an accessible app to bring antibiotic prescribing and antibiotic allergy decision-making to prescribers at point of care. Methods Using local hospital and community guidelines, the national formulary and in consultation with subspecialist teams, 31 algorithms were developed. Each algorithm asked questions including diagnosis, age, antibiotic allergy history and known colonization with-resistant organisms. Results The smartphone app (Script) uses the algorithms to advise on appropriate antimicrobial, dose, route and duration of treatment. Advice regarding IV-oral switch parameters and oral antibiotic choice is provided. If allergy is suspected symptom-based decision-making enables the user to choose an alternative agent or encourages allergy de-labeling. Further AMS occurs in some algorithms when advice is given not to prescribe antimicrobials. Conclusion Script for Pediatrics launched in NZ in March 2019 with >1000 users in the first 6 weeks. The most frequently accessed guidelines are otitis media, pneumonia and meningitis. Smartphone applications with local relevance and the ability to update in real-time may prove important tools, by providing easily accessible and intuitive advice to help support antimicrobial stewardship activities. This intervention has been rapidly adopted by pediatric hospital prescribers. The impact on prescribing in concordance with guidelines, timely intravenous to oral antibiotic switch and allergy de-labeling will be assessed. Disclosures All authors: No reported disclosures.

The Impact

Background: Antibiotic resistance has increased at alarming rates, driven predominantly by antibiotic overuse. Although most antibiotic use occurs in outpatients, antimicrobial stewardship programs have primarily focused on inpatient settings. A major challenge for outpatient stewardship is the lack of accurate and accessible electronic data to target interventions. We sought to develop and validate an electronic algorithm to identify inappropriate antibiotic use for outpatients with acute bronchitis. Methods: This study was conducted within the University of Pennsylvania Health System (UPHS). We used ICD-10 diagnostic codes to identify encounters for acute bronchitis at any outpatient UPHS practice between March 15, 2017, and March 14, 2018. Exclusion criteria included underlying immunocompromising condition, other comorbidity influencing the need for antibiotics (eg, emphysema), or ICD-10 code at the same visit for a concurrent infection (eg, sinusitis). We randomly selected 300 (150 from academic practices and 150 from nonacademic practices) eligible subjects for detailed chart abstraction that assessed patient demographics and practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for assessment of the electronic algorithm. Because antibiotic use is not indicated for this study population, appropriateness was assessed based upon whether an antibiotic was prescribed or not. Results: Of 300 subjects, median age was 61 years (interquartile range, 50–68), 62% were women, 74% were seen in internal medicine (vs family medicine) practices, and 75% were seen by a physician (vs an advanced practice provider). On chart review, 167 (56%) subjects received an antibiotic. Of these subjects, 1 had documented concern for pertussis and 4 had excluding conditions for which there were no ICD-10 codes. One received an antibiotic prescription for a planned dental procedure. Thus, based on chart review, 161 (54%) subjects received antibiotics inappropriately. Using the electronic algorithm based on diagnostic codes, underlying and concurrent conditions, and prescribing data, the number of subjects with inappropriate prescribing was 170 (56%) because 3 subjects had antibiotic prescribing not noted based on chart review. The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were the following: sensitivity, 100% (161 of 161); specificity, 94% (130 of 139); positive predictive value, 95% (161 of 170); and negative predictive value, 100% (130 of 130). Conclusions: For outpatients with acute bronchitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. This algorithm could be used to efficiently assess prescribing among practices and individual clinicians. The impact of interventions based on this algorithm should be tested in future studies.Funding: NoneDisclosures: None

The Impact

Background: The Tufts Medical Center Antimicrobial Stewardship (ASP) Team has partnered with the Massachusetts Department of Public Health (MDPH) to provide broad-based educational programs (BBEP) to long-term care facilities (LTCFs) in an effort to improve ASP and infection control practices. LTCFs have consistently expressed interest in individualized and hands-on involvement by ASP experts, yet they lack resources. The goal of this study was to determine whether “enhanced” individualized guidance provided by an ASP expert would lead to antibiotic start decreases in LTCFs participating in our pilot study. Methods: A pilot study was conducted to test the feasibility and efficacy of providing enhanced ASP and infection control practices to LTCFs. In total, 10 facilities already participating in MDPH BBEP and submitting monthly antibiotic start data were enrolled, were stratified by bed size and presence of dementia unit, and were randomized 1:1 to the “enhanced” group (defined as reviewing protocols and antibiotic start cases, providing lectures and feedback to staff and answering questions) versus the “nonenhanced” group. Antibiotic start data were validated and collected prospectively from January 2018 to July 2019, and the interventions began in April 2019. Due to staff turnover and lack of engagement, intervention was not possible in 2 of the 5 LTCFs randomized to the enhanced group, which were therefore analyzed as a nonenhanced group. An incidence rate ratios (IRRs) with 95% CIs were calculated comparing the antibiotic start rate per 1,000 resident days between periods in the pilot groups. Results: The average bed sizes for enhanced groups versus nonenhanced groups were 121 (±71.0) versus 108 (±32.8); the average resident days per facility per month were 3,415.7 (±2,131.2) versus 2,911.4 (±964.3). Comparatively, 3 facilities in the enhanced group had dementia unit versus 4 in the nonenhanced group. In the per protocol analysis, the antibiotic start rate in the enhanced group before versus after the intervention was 11.35 versus 9.41 starts per 1,000 resident days (IRR, 0.829; 95% CI, 0.794–0.865). The antibiotic start rate in the nonenhanced group before versus after the intervention was 7.90 versus 8.23 antibiotic starts per 1,000 resident days (IRR, 1.048; 95% CI, 1.007–1.089). Physician hours required for ASP for the enhanced group totaled 8.9 (±2.2) per facility per month. Conclusions: Although the number of hours required for intervention by an expert was not onerous, maintaining engagement proved difficult and in 2 facilities could not be achieved. A statistically significant 20% decrease in the antibiotic start rate was achieved in the enhanced group after interventions, potentially reflecting the benefit of enhanced ASP support by an expert.Funding: This study was funded by the Leadership in Epidemiology, Antimicrobial Stewardship, and Public Health (LEAP) fellowship training grant award from the CDC.Disclosures: None

The Impact

Abstract Background In the outpatient setting, the majority of antibiotic prescriptions are for acute respiratory infections (ARIs), but most of these infections are viral and antibiotics are unnecessary. We analyzed provider-specific antibiotic prescribing in a group of outpatient clinics affiliated with an academic medical center to inform future interventions to minimize unnecessary antibiotic use. Methods We conducted a cross-sectional study of patients who presented with an ARI to any of 15 The Emory Clinic (TEC) primary care clinic sites between October 2015 and September 2017. We performed multivariable logistic regression analysis to examine the impact of patient, provider, and clinic characteristics on antibiotic prescribing. We also compared provider-specific prescribing rates within and between clinic sites. Results A total of 53.4% of the 9600 patient encounters with a diagnosis of ARI resulted in an antibiotic prescription. The odds of an encounter resulting in an antibiotic prescription were independently associated with patient characteristics of white race (adjusted odds ratio [aOR] = 1.59; 95% confidence interval [CI], 1.47–1.73), older age (aOR = 1.32, 95% CI = 1.20–1.46 for patients 51 to 64 years; aOR = 1.32, 95% CI = 1.20–1.46 for patients ≥65 years), and comorbid condition presence (aOR = 1.19; 95% CI, 1.09–1.30). Of the 109 providers, 13 (12%) had a rate significantly higher than predicted by modeling. Conclusions Antibiotic prescribing for ARIs within TEC outpatient settings is higher than expected based on prescribing guidelines, with substantial variation in prescribing rates by site and provider. These data lay the foundation for quality improvement interventions to reduce unnecessary antibiotic prescribing.

Abstract Background Fluoroquinolone (FQ) antibiotics are frequently used in hospitalized patients to treat a wide range of infections but are often misused and implicated in antibiotic-associated adverse events. The purpose of this study is to evaluate the impact of Infectious Disease fellow (IDF)-driven antimicrobial stewardship program (ASP) interventions on inpatient FQ use. Methods This is a retrospective study of all admitted patients who received a FQ for greater than 48 hours from 01/01/2019 -12/31/2020 in an urban academic center. “Phase 1” (pre-intervention phase) covered 01/1/2019- 03/31/2019. “Phase 2” (intervention phase) covered 03/03/2020- 12/23/2020. In “Phase 2”, our ASP reviewed FQ use 2-3 days per week and an IDF provided feedback interventions that averaged 30-60 minutes of IDF time spent per day. We categorized FQ use as either: “appropriate”, “appropriate but not preferred”, or “inappropriate”, as determined by local clinical guidelines and ASP team opinion. We compared FQ use in both phases, indications for FQ use, and new Clostridioides difficile infections (CDI). Results A total of 386 patients are included (76 in “Phase 1”and 310 in “Phase 2”). Patient characteristics are similar (Table 1). Overall, 63 % of FQ use was empiric, and 50% FQ use was deemed “appropriate”, 28% “appropriate but not preferred”, and 22% “inappropriate”. In “Phase 2”, 126 interventions were conducted, with 86% of these accepted. Appropriate FQ use increased significantly in “Phase 2” vs. “Phase 1” (53.5% vs 35.5%, p = 0.008), with decrease in mean days of FQ use (4.38 days vs 5.87 days, p =.021). Table 2 shows “appropriate” FQ use by clinical indication. New CDIs occurred more in “Phase 1” vs. “Phase 2” (6.6% vs 0.6%, p=.001). Conclusion An IDF-driven ASP intervention has a positive impact on appropriate inpatient use of FQs in our hospital. This highlights a promising ASP model which not only improves appropriate use of FQ, but also offers an opportunity for IDF mentorship and use of available resources to promote ASPs.

Abstract Background The use of facility-specific guidelines and clinical decision-making tools are recommended by a number of organizations to improve the appropriateness of empiric antimicrobial prescribing; however, how to increase usage is not clear. We evaluated the impact of embedding antimicrobial stewardship (AS) electronic order sets (EOS) into the general medicine admission EOS in the context of an established AS program. Methods The standalone EOS for community-acquired pneumonia (CAP), urinary tract infection (UTI) and cellulitis were reviewed and simplified to only include the antibiotic section prior to embedding. The intervention was introduced on March 30, 2017 with pre-intervention period defined as January 1, 2016 to March 29, 2017 and post-intervention period as of March 30, 2017 to June 30, 2018. The primary outcome was the change in usage of embedded AS EOS compared with the corresponding standalone EOS using counts. In addition, other standalone AS EOS (i.e., Clostridioides difficile infection (CDI), etc) were used as a control. The secondary outcomes were the change in antibiotic usage de-emphasized in embedded EOS (i.e., ceftriaxone, ciprofloxacin, clindamycin, moxifloxacin) and predicted prescribing shifts to antibiotics in the embedded EOS (i.e., amoxicillin-clavulanate, azithromycin and sulfamethoxazole-trimethoprim) using Days of Therapy (DOT)/1000 patient-days (PD). Paired t-test was used to compare antibiotic usage pre- and post-intervention. Results The usage of standalone EOS remained similar pre- and post-intervention except for a 16-fold increased usage of CDI EOS. There were large increases in uptake of the embedded EOS compared with the standalone EOS: 11-fold () increase for CAP, 47-fold () increase for UTI and 24-fold () increase for cellulitis. In addition, there was a statistically significant decrease in ciprofloxacin (mean 16.6 DOT/1000-PD vs. 13.6 DOT/1000-PD, P = 0.026) and moxifloxacin usage (mean 9.3 DOT/1000-PD vs. 5.2 DOT/1000-PD) during the study time period. Conclusion Our study showed that simplifying AS EOS and embedding these into a more commonly used EOS is associated with a significant increase in EOS usage and uptake of AS recommended empiric antibiotics with a decrease in fluoroquinolone usage.

The Impact

Background: Numerous interventions have been used to reduce medication errors related to antiretroviral (ARV) therapy for hospitalized patients with HIV. Objective: This study assessed the impact of an antimicrobial stewardship (ASP) team intervention on reducing the rate of ARV therapy errors in patients admitted to an academic medical center. Methods: This observational, retrospective study included patients who received ARV therapy from June 2016 to December 2017. The primary outcome was evaluation of ASP team performance in detecting ARV medication errors in the inpatient setting. Errors were further categorized by type (interaction, dosing, regimen). The Mann-Whitney U test and χ2 tests were utilized to analyze continuous and categorical data, respectively. Results: Medication errors occurred in 51% of patients in the preintervention group (n = 152) and 48% of patients in the postintervention group (n = 203; P = 0.43). The most frequent medication error type was drug interactions in both groups, involving integrase strand transfer inhibitors and polyvalent cations (64% vs 67%). There was a significant difference between preintervention and postintervention groups regarding number of errors detected (13 vs 106, P < 0.001), corrected (12 vs 86, P < 0.001), and persisting at discharge (106 vs 18, P < 0.001). Conclusion and Relevance: Review of ARV regimens by an ASP team significantly decreased medication errors. Drug interactions are the most common medication error found in HIV-positive patients admitted to our academic center.
