Background: The disease caused by SARS-CoV-2, COVID-19, has caused a pandemic leading to strained healthcare systems worldwide and an unprecedented public health crisis. Lower respiratory tract infections (LRTIs) and hypoxia caused by COVID-19 has led to an increase in hospitalizations. We sought to define the impact of COVID-19 on antimicrobial use and antimicrobial resistance (AMR) in an urban safety-net community hospital. Methods: Retrospective review of antimicrobial use and AMR in a 151-bed urban community hospital. Antimicrobial use was calculated in days of therapy per 1,000 patient days (DOT/1,000 PD) for ceftriaxone, piperacillin-tazobactam and meropenem during 2019 and 2020. Ceftriaxone, piperacillin-tazobactam and meropenem were reviewed for calendar year 2019 and 2020. AMR was assessed by comparing the carbapenem resistant Enterobacteriaceae (CRE) infection incidence rate per 1,000 patient days between 2019 and 2020. Results: The average quarterly DOT/1,000 PD increased from 359.5 in 2019 to 394.25 in 2020, with the highest increase in the second and fourth quarters of 2020, which temporarily correspond to the first and second waves of COVID-19. Ceftriaxone and meropenem use increased during the first and second waves of COVID-19. Piperacillin-tazobactam use increased during the first wave and declined thereafter (Figure 1). Rates of CRE increased from a quarterly average of 0.57 to 0.68 (Figure 2). Conclusions: Antimicrobial pressure increased during the first and second waves of COVID-19. Ceftriaxone was the most commonly used antimicrobial, reflecting internal guidelines and ASP interventions. CRE rates increased during COVID-19. This finding may be due to an overall increase in antimicrobial pressure in the community and in critically ill patients. Antibiotics are a precious resource, and antimicrobial stewardship remains important during the COVID-19 pandemic. Appropriate use of antimicrobials is critical to preventing AMR.Funding: NoDisclosures: None

Abstract Background Lower respiratory tract infections (LRTIs) are one of the most common infectious disease-related emergency department (ED) visits in the United States. The ID Society of America and the Agency for Healthcare Research and Quality support the use of procalcitonin (PCT) for antimicrobial stewardship (ASP) in LRTI. Though not widely available, awareness and access to PCT is rising. At our facility, PCT became available in February 2018. The aim of our study is to assess the impact of PCT at an urban community hospital and identify possible targets for ASP interventions. Methods Retrospective review of cases from February to August 2018. Cases from the ED were selected for review. Appropriateness of testing was assessed, defined as guideline-based use for cessation of antibiotics in uncomplicated LRTIs without critical illness or immunosuppression. Demographic variables and clinical characteristics, such as, diagnosis, antimicrobial use and PCT levels were obtained. Results PCT was ordered 268 times hospital-wide, of which 160 (60%) were in the ED. Ages ranged from 0–90, with an average of 47. Most cases were male (51%). Appropriate testing for LRTI occurred in 33 (29%) cases. Antimicrobials were used in 75% of cases with low (< 0.5) PCT levels (Figure 1). Length of stay (LOS) was higher in groups that received antimicrobials (Figure 2). Testing was not appropriate in 127 cases (71%), with upper respiratory (21%), soft-tissue (17%), genitourinary (15%) and abdominal (13%) infections as the most common reasons for testing. Other diagnosis included alcohol withdrawal, seizures and altered mental status. Cumulative cost of PCT testing was $24000, of which $19050 was not consistent with guidelines. Conclusion Clinicians routinely ordered PCT in the ED. Antimicrobials were used for LRTIs despite low PCT levels. This may have contributed to higher LOS and excess antimicrobial use. Unwarranted PCT testing had a cost of $19050. As PCT becomes widely available in hospitals across the United States, education and decision support by ASP to clinicians may be needed to enhance guideline-appropriate evidence-based use of PCT. Targeted ASP interventions in the ED may have cost savings by reducing excess testing, length of stay and improving antimicrobial use. Disclosures All authors: No reported disclosures.

Abstract Background Antimicrobial stewardship (AS) implementation is challenging in resource-limited settings such as smaller community hospitals that may lack dedicated personnel resources or have limited access to infectious diseases experts with dedicated time for AS. Few studies have evaluated the impact of interdisciplinary rounds as a strategy to optimize antimicrobial use (AU) in the community hospital setting. Methods We evaluated the impact of interdisciplinary rounds in a 280-bed acute care nonteaching, community hospital with an established ASP. The primary outcome was facility-wide antibiotic utilization pre- and post-implementation. Rounds included key healthcare personnel (hospitalists, clinical pharmacists, case managers, nurses) reviewing all patients on inpatient wards Monday through Friday, with a discussion of diagnosis, antibiotic selection, dosing, duration, and anticipated discharge plans. AU was compared for a 7-month post-intervention period (June 1, 2018–December 31, 2018) vs. similar months in 2017 based on days of therapy (DOT)/1,000 patient-days and length of therapy (LOT) per antimicrobial use admission. In addition, trends in AU for the post-intervention period were compared with the previous 17 months (January 1, 2017–May 31, 2018) using segmented binomial regression. Results Interdisciplinary rounds incorporating AS principles was associated with a decrease in overall AU in this facility, with a significant decrease of 16.33% (P < 0.0001) in DOT/1,000 pd in the first month and was stable (decrease of 1.1% per month, P = 0.15) thereafter (Figure 1). There was no significant change in LOT/admission after the first month of the intervention, but the trend demonstrated a 2% per month decrease (P < 0.03) thereafter (Figure 2). Comparing 2018 intervention months with similar months of 2017, the use of antibacterial agents decreased on average by 191.3 (95% CI −128.2 to −254.4) DOT/1,000 patient-days (Figure 3) and 0.546 (95% CI: −0.28 to −0.81) days per admission (Figure 4). Conclusion In this community hospital with an existing antimicrobial stewardship program, implementation of interdisciplinary rounds was associated with a substantial decrease in antimicrobial use. This was sustained for at least a 7-month period. Disclosures All authors: No reported disclosures.

Background: The disease caused by SARS-CoV-2, COVID-19, has caused a pandemic leading to strained healthcare systems worldwide and an unprecedented public health crisis. The hallmark of severe COVID-19 is lower respiratory tract infection (LRTI) and hypoxia requiring hospitalization. A paucity of data on bacterial coinfection and a lack of therapeutic options for COVID-19 during the first surge of cases has increased pressure on antimicrobial use and has challenged antimicrobial stewardship programs (ASPs). We implemented a multimodal approach to antimicrobial stewardship in an urban safety-net community hospital targeting selection and duration of therapy. Methods: Retrospective review of cases during the first wave of COVID-19 in a 151-bed urban safety-net community hospital from March to June 2020. EMR order sets (Figure 1) and prospective audit and feedback by ASPs targeting empiric antimicrobial selection and duration were implemented as part of the COVID-19 response. Hospitalized patients with COVID-19 were reviewed retrospectively. Demographic information was collected. Data on antimicrobial use were tabulated, including selection and duration of antimicrobials (Figure 1). Results: In total, 302 patients were reviewed, of whom 221 (73%) received empiric antimicrobials. The most commonly used antimicrobials were ceftriaxone and azithromycin (Figure 2). Days of therapy per 1,000 patient days (DOT/1,000 PD) for ceftriaxone increased from 71 in the quarter prior to 113 during the study period. Average duration of therapy was 6 days. In the ICU, average duration was 8 days compared to 5 days in non-ICU settings. Average durations of parenteral therapy were 5.54 days in the ICU and 3.36 days in non-ICU settings. Procalcitonin was obtained in 37 cases (17%) and ranged from 0.09 to 12.57 ng/mL, with an average of 1.21 ng/mL. No cases had documented bacterial coinfection (Figure 1). Conclusions: Antimicrobials were commonly prescribed during the first wave of COVID-19 in a safety-net community hospital. Procalcitonin did not guide therapy nor did lack of documented coinfection change physician behavior. With limited resources, ASP successfully guided clinicians toward IDSA guideline recommendations for selection and duration, as evidenced by antimicrobial use. During this unprecedented surge of LRTIs, a multimodal approach to antimicrobial stewardship was used and guided toward early transition to oral agents and shorter durations.Funding: NoDisclosures: None

Abstract Background Automatic antimicrobial stop orders (ASOs) are a stewardship initiative used to decrease days of therapy, prevent resistance, and reduce drug costs. Limited evidence outside of the perioperative setting exists on the effects of ASOs on broad spectrum antimicrobial use, discharge prescription duration, and effects of missed doses. This study aims to evaluate the impact of an ASO policy across a health system of adult academic and community hospitals for treatment of intra-abdominal (IAI) and urinary tract infections (UTI). ASO Outcome Definitions ASO Outcomes Methods This multicenter retrospective cohort study compared patients with IAI and UTI treated before and after implementation of an ASO. Patients over the age of 18 with a diagnosis of UTI or IAI and 48 hours of intravenous (IV) antimicrobial administration were included. Patients unable to achieve IAI source control within 48 hours or those with a concomitant infection were excluded. The primary outcome was the difference in sum length of antimicrobial therapy (LOT). Secondary endpoints include length and days of antimicrobial therapy (DOT) at multiple timepoints, all cause in hospital mortality and readmission, and adverse events such as rates of Clostridioides difficile infection. Outcomes were also evaluated by type of infection, hospital site, and presence of infectious diseases (ID) pharmacist on site. Results This study included 119 patients in the pre-ASO group and 121 patients in the post-ASO group. ASO shortened sum length of therapy (LOT) (12 days vs 11 days respectively; p=0.0364) and sum DOT (15 days vs 12 days respectively; p=0.022). This finding appears to be driven by a decrease in outpatient LOT (p=0.0017) and outpatient DOT (p=0.0034). Conversely, ASO extended empiric IV LOT (p=0.005). All other secondary outcomes were not significant. Ten patients missed doses of antimicrobials due to ASO. Subgroup analyses suggested that one hospital may have influenced outcomes and reduction in LOT was observed primarily in sites without an ID pharmacist on site (p=0.018). Conclusion While implementation of ASO decreases sum length of inpatient and outpatient therapy, it may not influence inpatient length of therapy alone. Moreover, ASOs prolong use of empiric intravenous therapy. Hospitals without an ID pharmacist may benefit most from ASO protocols. Disclosures All Authors: No reported disclosures

AbstractAntimicrobial stewardship programs typically use days of therapy to assess antimicrobial use. However, this metric does not account for the antimicrobial spectrum of activity. We applied an antibiotic spectrum index to a population of very-low-birth-weight infants to assess its utility to evaluate the impact of antimicrobial stewardship interventions.

Abstract Background The use of anti-Pseudomonal β-lactam (APBL) agents has significantly increased in the past decade, carrying higher costs and contributing to antimicrobial pressure. Antimicrobial stewardship (ASP) can promote evidence-based antimicrobial selection and mitigate excess APBL use. We implemented a comprehensive ASP with syndrome-based prospective audit and feedback (PAF) at an urban community hospital. The goal of this study is to assess the impact of syndrome-based PAF on APBL use, C. difficile rates and cost. Methods ASP with all CDC core elements was implemented at a 151-bed community hospital in October 2017. Syndrome-based guidelines and PAF was established and overseen via direct communication with an ID physician. Days of therapy (DOT), cost and C. difficile rates were assessed 12 months before and after ASP. DOT for APBL and non-APBL utilization was tabulated by unit and paired t-test performed. Results Most cases reviewed by PAF (51%) were represented in our syndrome-based treatment guidelines (Figure 1). Soft tissue (33%) and intra-abdominal (24%) infections were the most common syndromes. Change to guideline was the most common PAF intervention (62%) followed by de-escalation (30%). At 12 months, total DOT/1,000 increased (392.5 vs. 404) while the proportion of parenteral antimicrobials used decreased (71% vs. 65%). Antibiotic expenditures decreased by 23%, with a reduction in APBL of 20% and non-APBL of 10% (Table 1). Statistically significant reductions APBL use in non-ICU settings (P = 0.0139) and statistically significant increases in non-APBL in ICU settings occurred (P = 0.0001) (Figure 2 and 3). C difficile rates decreased from 21% (3.27 vs. 2.56). Conclusion Syndrome-based PAF was successfully implemented. A reduction in APBL use was seen in non-ICU settings, where evidence-based de-escalation may be more feasible. APBL use remained high in the ICU but was guideline consistent. A rise in non-APBL use also occurred. Certain critical illness syndromes warrant APBLs, but PAF may promote culture-directed and syndrome-specific treatments. ASP increased guideline-based therapy and contributed to decreased broad-spectrum antimicrobial use, antimicrobial expenditures and C difficile rates. Syndrome based PAF can be successfully implemented in community settings. Disclosures All authors: No reported disclosures.

Abstract Background Small hospitals in the US may lack access to infectious diseases (ID) expertise despite similar rates of antimicrobial use and drug-resistant bacteria as larger hospitals. A tele-antimicrobial stewardship program (TASP) is a force multiplier, expanding access to specialty care, training, and guidance on appropriate resource utilization. Data on the impact of TASPs in community or rural inpatient settings is limited. Methods We established a TASP at a 160-bed hospital in Armstrong County, PA (population &lt; 5000) in September 2020. Tele-ID consult services were already being used (Figure 1). A non-local ID pharmacist or ID physician performed prospective audits and provided feedback with 1 local pharmacist on a 30-minute video conference call daily. At TASP implementation, all patients receiving intravenous (IV) fluoroquinolones, metronidazole, and azithromycin were reviewed. Figure 1 shows the additional support following TASP implementation, including addition of ceftriaxone, carbapenems, IV vancomycin, and tocilizumab to daily reviews. A patient monitoring form was developed to track interventions and the local pharmacists were trained in documentation. Table 1 lists other TASP features implemented. Figure 1. TASP Timeline Table 1. TASP Accomplishments Results From 09/01/2020 to 04/30/2021, 304 stewardship opportunities were identified and 77% of interventions were accepted. Recommending a duration of therapy was accepted most frequently (93.5%) and de-escalation of therapy least frequently (69.6%) (Table 2). Recommending an ID consultation or diagnostic testing was always accepted but only comprised 6.2% of all interventions. Daily calls involved an average of 5 patient reviews. Monthly antimicrobial use declined on average from 673 DOT (days of therapy)/1000 PD (patient days) to 638 DOT/1000 PD (Figure 2). Daily calls were cancelled on 31/166 weekdays (18.7%) due to staffing shortages. Table 2. TASP Interventions (9/2020 - 4/2021) Figure 2. Monthly Antimicrobial Use in Days of Therapy (DOT) per 1000 Patient Days (4/2019 - 5/2021) Conclusion Implementation of TASP in a community hospital resulted in a high percentage of accepted stewardship interventions and lower antimicrobial usage. Success is dependent on robust educational efforts, establishing strong relationships with local providers, and involvement of key stakeholders. Lack of dedicated stewardship time for local pharmacists is a very significant barrier. Disclosures Erin K.

Abstract Background Neutralizing monoclonal antibodies (mAbs) bind to the receptor binding domain of the spike protein of SARS-CoV-2. In November 2020, several mAbs were issued an EUA by the FDA as single-dose intravenous (IV) infusions for treatment of mild to moderate COVID-19. mABs were allocated to local health facilities capable of administering infusions and managing side effects. Creating an outpatient infusion program during the COVID-19 winter surge can be logistically difficult. Our goal was to implement a mAb outpatient infusion program at an urban safety-net community hospital designed to serve communities most heavily impacted by COVID-19. Methods The emergency department (ED) fast-track was repurposed for the mAb program with protocols from the infectious diseases physician and antimicrobial stewardship. Education materials with indications for mAbs were distributed in surrounding clinics serving our community. The program was available to all patients meeting criteria outlined in the protocol, 24/7, including but not limited to current ED patients and referrals from facilities in the vicinity. Results Between December 1, 2020 and March 1, 2021, a total of 37 patients were treated: 51% male, 57% Hispanic or Latinx, 27% Black, and 95% (35) represented ZIP codes with high COVID-19 burden (Figure 1). Bamlanivimab was used for each instance and all infusions met criteria. Patient indications for mAb infusion are listed in Figure 2. Parenteral antibiotics were given to 10.8% and 35% received oral antibiotics upon discharge. At 30 days post-infusion, 8% (3) required hospitalization and there were no deaths. Zip codes with high COVID-19 disease burden served by our mAB infusion program Distribution of patients who received mAB infusions by indication Conclusion A mAb outpatient infusion program was successfully deployed in a safety-net community hospital. We believe strengths of the program included the flexible infusion hours and convenient referral site for patients and providers. Of importance, this program was able to provide services to minorities from ZIP codes most heavily impacted by COVID-19. Unfortunately, antibacterial use was common and may reflect broader unnecessary use in COVID-19 patients. Whilst mAb treatment was deemed appropriate in all instances via protocol inclusion criteria, antibacterial stewardship programs may need to expand to ED settings for COVID-19 management.
