Abstract Background Vancomycin and piperacillin-tazobactam (VPT) combination therapy is associated with nephrotoxicity and provides broad-spectrum coverage that may be unnecessary. We conducted a pre-post implementation study to assess the impact of an audit and feedback program for VPT at our academic medical center. Methods Automated alerts were used to identify patients on VPT at the University of Washington Medical Center (UWMC)-Montlake (ML) and UWMC-Seattle Cancer Care Alliance (SCCA) hospitals. Baseline data was collected on patients from 1/20/20-6/2/20: electronic medical records were reviewed for antibiotic indication, duration, renal function, and presence of Infectious Disease (ID) consult. From 6/25/20-10/31/20, all patients on combination therapy without an ID consult were reviewed by the antimicrobial stewardship programs at ML and SCCA, respectively. If intervention was warranted, the ML steward discussed the case with the provider then documented the conversation. The SCCA steward, instead, discussed the case with the team pharmacist. The primary outcome was change in VPT duration post intervention. Secondary outcomes included nephrotoxicity rates and carbapenem escalation. Results Prior to the intervention, 66 ML and 33 SCCA patients were started on the combination compared to 110 ML and 50 SCCA patients post-intervention. Overall, 50% of ML and 14% of SCCA patients were on surgical primary services. Amongst ML patients, there was a decrease in patients on VPT for > 4 days (22 % to 8%), incidence of renal injury (30.3% to 10%), and percentage of ID consults (53.0% to 43.6%). Escalation to a carbapenem was stable (4.5% to 4.5%). In SCCA patients the percentage of patients on VPT for > 4 days decreased slightly (18.2% to 15.2%), incidence of renal injury was stable (18.2% to 18%), percentage of ID consults increased (45.5% to 50.0%), and escalation to a carbapenem was stable (12.1% vs 13.5%). Conclusion Prospective audit and feedback of VPT was associated with a decrease in duration and nephrotoxicity in ML but not SCCA patients. The difference in outcomes could be due to the patient populations, primary services, or intervention process. This study highlights the importance of tailoring interventions even within the same medical system. Disclosures All Authors: No reported disclosures

Abstract Background Facilities with robust antimicrobial stewardship programs often have infectious disease (ID) pharmacists with devoted time to complete antimicrobial stewardship initiatives. Smaller facilities with limited resources or lacking ID pharmacists, may encounter challenges meeting antimicrobial stewardship regulatory requirements. The goal of this study is to assess the impact of a staff pharmacist-driven prospective audit and feedback program in a small community hospital. Methods A pre- and post-intervention study was performed to assess the primary outcome of days of therapy per 1,000 patient days (DOT) for targeted antimicrobials (ciprofloxacin, levofloxacin, piperacillin/tazobactam, cefepime, ceftazidime). Secondary outcomes were antibiotic expenditures and rates of Clostridioides difficile infection (CDI). Results Significant decreases in DOT were observed for piperacillin/tazobactam (29.88 vs. 9.25; p < 0.001), ciprofloxacin (23.22 vs. 9.97; p < 0.001), levofloxacin (11.2 vs. 5.07; p < 0.001) and overall antipseudomonal DOT (62.91 vs. 51.67; p < 0.001). There was no difference in ceftazidime DOT (8.75 vs. 6.47; p= 0.083) and an increase in cefepime DOT (20.47 vs. 34.35; p < 0.001). A trend towards decreased rates of CDI was seen (4.9/10,000 patient days vs. 2.64/10,000 patient days; p= 0.931). There were significant decreases in antibiotic expenditures for piperacillin/tazobactam ($52,498 vs. $10,937; p < 0.001), levofloxacin ($2,168 vs. $672; p < 0.001), ciprofloxacin ($6,700 vs. $1,954; p < 0.001). Lower expenditures for ceftazidime were seen ($9,952 vs. $7,457; p= 0.29). Cefepime expenditures increased ($25,638 vs. $40,097; p= 0.001). An overall decrease in the expenditure for the targeted antibiotics was seen ($95,715 vs. $62,837; p < 0.001). Conclusion Implementation of a staff pharmacist-driven prospective authorization and feedback program led to a significant decrease in DOT and antibiotic expenditures for several targeted antibiotics and a trend towards decreased rates of CDI. Despite increased DOT and expenditures for cefepime, there was an overall decrease amongst the targeted antibiotics. With proper implementation, staff pharmacists can significantly benefit antimicrobial stewardship initiatives. Disclosures All Authors: No reported disclosures

Prospective Audit And Feedback

Background: In September 2018, pharmacy antimicrobial stewardship (AMS) services were expanded to include weekends at this academic medical center. Activities performed by AMS pharmacists on the weekends include blood culture rapid diagnostic (RDT) review, antiretroviral therapy (ART) review, prospective audit and feedback (PAF) utilizing clinical decision support, vancomycin dosing, and operational support. The purpose of this study was to assess the operational and clinical impact of these expanded AMS services. Methods: This single-center, quasi-experimental study included data from weekends before (9/2017–11/2017) and after (9/2018–11/2018) implementation. The descriptive primary outcome was the number of activities completed for each AMS activity type in the post-implementation group only. Secondary outcomes were time to AMS opportunity resolution, time to escalation or de-escalation following PAF or RDT alert, time to resolution of miscellaneous AMS related opportunities, length of stay (LOS), and antimicrobial use outcomes. Results: During the post-implementation period 1258 activities were completed, averaging 97/weekend. Inclusion criteria for time to resolution outcomes were met by 72 patients pre-implementation and 59 patients post. The median (IQR) time to AMS opportunity resolution decreased from 18.5 hours pre-intervention (7.7-35.7) to 8.5 hours post-intervention (IQR 1.8-14.0), p < 0.01. Time to escalation was 11.6 hours compared to 1.7 hours (p = 0.1), de-escalation 16.7 hours compared to 10.8 hours (p = 0.03), and miscellaneous opportunity 40.8 hours compared to 13.2 hours (p = 0.01). No differences were observed in LOS or antimicrobial use outcomes. Conclusion: Presence of pharmacist-driven weekend AMS services significantly reduced time to resolution of AMS opportunities. These data support the value of weekend AMS services.

Abstract Background High regulatory burden on hospital-onset (HO) infections has increased performance pressure on infection prevention programs. Despite the availability of comprehensive prevention guidelines, a major challenge has been communication with frontline staff to integrate appropriate prevention measures into practice. The objective of our study was to evaluate the impact of educational intervention on HO CAUTI rates and urinary catheter days. Methods At the University of Mississippi Medical Center, Infection prevention (IP) reports unit-based monthly HO infections via email to respective unit managers and ordering physician providers. Starting May 2018, IP assessed compliance to CAUTI prevention strategies per SHEA/IDSA practice recommendations (2014). HO CAUTI cases with noncompliance were labeled as “preventable” infections and educational justification was provided in the email report. No other interventions were introduced during the study period. CAUTI data were collected using ongoing surveillance per NHSN and used to calculate rates per 1,000 catheter days. One-way analysis of variance (ANOVA) was used to compare pre- and post-intervention data. Results Prior to intervention (July 2017–March 2018), HO CAUTI rate was 1.43 per 1,000 catheter days. In the post-intervention period (July 2018–March 2019), HO CAUTI rate decreased to 0.62 per 1,000 catheter days. Comparison of pre- and post-intervention rates showed a statistically significant reduction in HO CAUTIs (P = 0.04). The total number of catheter days reduced, but the difference was not statistically significant (8,604 vs. 7,583; P = 0.06). Of the 14 HO CAUTIs in post-intervention period, 64% (8/14) were reported preventable. The preventable causes included inappropriate urine culturing practice in asymptomatic patients (5) or as part of pan-culture without urinalysis (2), and lack of daily catheter assessment for necessity (1). Conclusion At our institute, regular educational feedback by IP to frontline staff resulted in a reduction of HO CAUTIs. Feedback measure improved accountability, awareness and engagement of frontline staff in practicing appropriate CAUTI prevention strategies. Disclosures All authors: No reported disclosures.

Abstract Background A candidemia treatment bundle (CTB) may increase adherence to guideline recommended candidemia management and improve patient outcomes. The purpose of this study was to evaluate the impact of a best practice alert (BPA) and order-set on optimizing compliance with all CTB components and patient outcomes. Methods A single center, pre-/post-intervention study was completed at Grady Health System from August 2015 to August 2017. Post-CTB intervention began August 2016. The CTB included a BPA that fires for blood cultures positive for any Candida species to treatment clinicians upon opening the patient’s electronic health record. The BPA included a linked order-set based on treatment recommendations including: infectious diseases (ID) and ophthalmology consultation, repeat blood cultures, empiric echinocandin therapy, early source control, antifungal de-escalation, intravenous to oral (IV to PO) switch, and duration of therapy. The primary outcome of the study was total adherence to the CTB. The secondary outcomes include adherence with the individual components of the CTB, 30-day mortality, and infection-related length of stay (LOS). Results Forty-five patients in the pre-group and 24 patients in the CTB group with candidemia were identified. Twenty-seven patients in the pre-group and 19 patients in the CTB group met inclusion criteria. Total adherence with the CTB occurred in one patient in the pre-group and threepatients in the CTB group (4% vs. 16%, P = 0.29). ID was consulted in 15 patients in the pre-group and 17 patients in the CTB group (56% vs. 89%, P = 0.02). Source control occurred in three and 11 patients, respectively (11% vs. 58% P &lt; 0.01). The bundle components of empiric echinocandin use (81% vs. 100%, P = 0.07), ophthalmology consultation (81% vs. 95%, P = 0.37), and IV to PO switch (22% vs. 32%, P = 0.5) also improved in the CTB group. Repeat cultures and antifungal de-escalation were similar among groups. Thirty-day mortality decreased in the CTB group by 10% (26% vs. 16%, P = 0.48). Median iLOS decreased from 30 days in the pre-group to 17 days in the CTB group (P = 0.05). Conclusion The CTB, with a BPA and linked order-set, improved guideline recommended management of candidemia specifically increasing the rates of ID consultation and early source control. There were quantitative improvements in mortality and iLOS. Disclosures All authors: No reported disclosures.

Abstract Background Hoop’s Family Children’s Hospital is a pediatric hospital with 72 beds, nested within Cabell Huntington Hospital. There is an established adult antibiotic stewardship program (ASP), however, since 2014 there has not been a pediatric infectious disease (ID) specialist and no pediatric ASP. With the recent hire of a pediatric ID specialist in Oct 2019 and the formation of a targeted pediatric ASP, we tracked the use of ceftriaxone (CRO) in our facility. Methods Starting January 2020, education was provided to pediatric providers in regards to appropriate CRO dosing and clinical indications via email communication. The main goals were to limit 100mg/kg/day dosing to severe infections and reduce CRO use in community-acquired pneumonia. This was sustained through intermittent prospective audits and feedback. A retrospective chart review was done from 2019-2021 for the months of January, April and December of each year. Patients ≤18 years of age who received CRO were included. Dosing, interval frequency, indication, and treatment duration were reviewed. Patients who received a single dose of CRO were excluded. Results From Jan 2019 – April 2021, 391 patient charts were reviewed (189 in the pre-intervention period and 202 in the post intervention period). There were no significant differences in age, race/ethnicity and gender in the two study groups. In the pre-intervention period, 86% of patients were prescribed CRO at severe infection dosing vs 33% in the post intervention period (p&lt; 0.0001) (Figure 1). When dosing was paired with indication, only 20% of patients in the pre intervention period had the appropriate dosing per clinical indication compared to 83% in the post intervention period (p&lt; 0.0001) (Figure 2). We also saw that in the pre-intervention period the most common indication for CRO was pneumonia (66%), which decreased to 57% in 2020 and to 35% in 2021 (p&lt; 0.0001) (Figure 3). Figure 1 describes the percentage of patients receiving ceftriaxone at severe infection dosing. This changed from an average of 86% in the pre-intervention period to 33% in the post-intervention period. Figure 2 describes the percentage of patients receiving ceftriaxone at the appropriate dosing dependent on the clinical indication provided. This changed from 20% in the pre-intervention period to closer to 90% in the post-intervention period. Conclusion Pediatric specific ASP efforts and expertise proved to be crucial in appropriate CRO use in our institution. With a feasible education strategy and targeted prospective audit and feedback, there has been a sustained impact in inappropriate CRO use. This underscores the importance of targeted pediatric ASP efforts in pediatric hospitals within larger adult hospitals. Disclosures All Authors: No reported disclosures

Abstract Background Clostridium difficile infections (CDI) pose a growing threat to hospitalized patients. This study assesses the impact of changing from a nucleic acid amplification test (NAAT) to a stepwise testing algorithm (STA) by using an enzyme immunoassay (GDH and toxin A/B) and confirmatory NAAT confirmation in specific cases. Methods In an 885 bed academic medical center a 24 month pre-/post design was used to assess the effect of the STA for the following parameters: rates of enterocolitis due to C.diff (CDE), NHSN C.diff LabID events, CDI complications, mortality, antimicrobial prescription patterns, cluster occurrences; and testing, treatment, and isolation costs. Inpatient data were extracted from ICD-9/10 diagnosis codes, infection prevention, and laboratory databases. Results The STA significantly decreased the number of CDE ICD9/10 codes, HO, CO, and CO-HCFA C.diff LabID event rates by 65%, 78%, 75%, and 75%, respectively. Similar reductions were noted for associated complications such as NHSN defined colon surgeries (-61%), megacolon (-64%), and acute kidney failure (-55%). CDE unrelated complication rates for colon surgeries and acute kidney failure remained constant while the diagnosis of megacolon decreased but not significantly (-71%; P &gt; 0.05). Inpatient mortality did not change with or without CDE. Significant reductions were observed in the use of oral metronidazole (total: -32%; CDE specific: -70%) and vancomycin (total: -58%; CDE specific: -61%). There were no clusters detected pre-/post STA introduction. The need for isolation decreased from 748 to 181 patients post-intervention (-76%; P &lt; 0.05). Annual cost savings were over $175,000 due to decreases in laboratory testing followed by isolation, and antibiotic use. Conclusion The switch to an STA from NAAT did not affect the diagnosis, treatment, or control of clinically relevant CDI in our institution. Benefits included avoidance of unnecessary antibiotic treatment, reduction in isolation, achieving publicly reported objectives, and costs savings. Selection of clinically relevant tests can help to improve hospitalization and treatment of patients and should be considered as part of diagnostic stewardship.

OBJECTIVETo describe the impact of rapid diagnostic microarray technology and antimicrobial stewardship for patients with Gram-positive blood cultures.DESIGNRetrospective pre-intervention/post-intervention study.SETTINGA 1,200-bed academic medical center.PATIENTSInpatients with blood cultures positive for Staphylococcus aureus, Enterococcus faecalis, E. faecium, Streptococcus pneumoniae, S. pyogenes, S. agalactiae, S. anginosus, Streptococcus spp., and Listeria monocytogenes during the 6 months before and after implementation of Verigene Gram-positive blood culture microarray (BC-GP) with an antimicrobial stewardship intervention.METHODSBefore the intervention, no rapid diagnostic technology was used or antimicrobial stewardship intervention was undertaken, except for the use of peptide nucleic acid fluorescent in situ hybridization and MRSA agar to identify staphylococcal isolates. After the intervention, all Gram-positive blood cultures underwent BC-GP microarray and the antimicrobial stewardship intervention consisting of real-time notification and pharmacist review.RESULTSIn total, 513 patients with bacteremia were included in this study: 280 patients with S. aureus, 150 patients with enterococci, 82 patients with stretococci, and 1 patient with L. monocytogenes. The number of antimicrobial switches was similar in the pre–BC-GP (52%; 155 of 300) and post–BC-GP (50%; 107 of 213) periods. The time to antimicrobial switch was significantly shorter in the post–BC-GP group than in the pre–BC-GP group: 48±41 hours versus 75±46 hours, respectively (P<.001). The most common antimicrobial switch was de-escalation and time to de-escalation, was significantly shorter in the post-BC-GP group than in the pre–BC-GP group: 53±41 hours versus 82±48 hours, respectively (P<.001). There was no difference in mortality or hospital length of stay as a result of the intervention.CONCLUSIONSThe combination of a rapid microarray diagnostic test with an antimicrobial stewardship intervention improved time to antimicrobial switch, especially time to de-escalation to optimal therapy, in patients with Gram-positive blood cultures.Infect Control Hosp Epidemiol 2016;1–6

Abstract Background Antimicrobial resistance (AMR) is an increasing threat to public health and antimicrobial consumption is a primary driver of resistance. Many studies have shown that the implementation of an antibiotic stewardship program (ASP) improves prescribing of antibiotics and can reduce AMR. Purpose of the study was to assess the impact of a successful ASP, implemented for four years, on AMR in our 427-bed tertiary general hospital. Methods We monitored pharmacy data for the years 2015 (pre-intervention) and 2016-2019 (post-intervention) for antibiotic consumption (DDD/100 bed-days) and resistance rates. AMR data were obtained from the clinical microbiology laboratory’s electronic database. To achieve the goals of ASP we used a range of interventions as pre-authorization strategy for the protected antibiotics (tigecycline, carbapenems, quinolones, glycopeptides, daptomycin, colistin, linezolid), prospective audit and feedback with direct intervention, de-escalation or switch from iv to oral administration and appropriate selection and duration of chemoprophylaxis in surgery. Results Significant reductions were observed for: total antibiotics, colistin, carbapenems, quinolones and tigecycline consumption during study period. Significantly lower resistance rates were documented in 2019 compared to 2015 for Pseudomonas aeruginosa and for Klebsiella pneumoniae. As for Acinetobacter baumannii isolates, which in our hospital are highly-resistant exhibiting &gt;90% resistance to carbapenems, no significant changes were noted during the study period. Infections caused by Gram-positive pathogens are less prevalent in our hospital. Lower rates of vancomycin-resistant enterococci were noted after the implementation of our ASP (30.4% in 2019 vs. 50.0% in 2015 for E. faecium and 0.6% vs. 6% for E. faecalis, respectively), whereas methicillin-resistant S. aureus isolates increased (40% in 2019 vs. 31.1% in 2015), possibly because most of these infections were not hospital-acquired. Resistance rates of Pseudomonas and Klebsiella Conclusion Our ASP was successful in reducing antibiotic consumption and AMR for important pathogens. Disclosures All Authors: No reported disclosures

Abstract Background Facility-specific treatment guidelines are a priority intervention recommended in the CDC Core Elements of Hospital Antimicrobial Stewardship Programs (ASPs). Our ASP sought to improve adherence to the facility C. difficile infection (CDI) treatment guideline by implementing prospective audit and feedback of CDI cases, changing fidaxomicin from being restricted to Infectious Diseases consult use, to only requiring prospective audit and feedback, and allowing fidaxomicin and oral vancomycin orders only through the order set. This study reviews the impact of these interventions. Methods This single-center retrospective quasi-experimental study evaluated inpatient CDI lab events 3 months pre-intervention (10/1/2019-12/31/2019) and post-intervention (10/14/2020-1/14/2021). Patient and treatment data was evaluated via chart review. The primary outcome was adherence to CDI treatment guideline. ASP intervention types were categorized. Statistical analyses were performed using Chi-squared or Fischer’s exact, where appropriate. Results Baseline characteristics were well matched between the 58 and 70 patients pre and post intervention respectively (Table 1). ASP interventions resulting from the prospective audit and feedback are described in Table 2 and overall acceptance rates were high (88%). Guideline adherence improved significantly from 71% pre to 90% post-intervention (p=0.005). Reasons for non-adherence included vancomycin dose incorrect for the severity of illness (9 pre vs 2 post), inappropriate duration (4 pre vs 0 post), use of combination therapy in non-fulminant disease (5 pre vs 3 post), and not using fidaxomicin for recurrent disease (3 pre vs 2 post). Clinical outcomes pre and post intervention were not different in this small sample size: colectomy 1 (2%) vs 1 (1%) p=1, 60 day all- cause mortality 15 (26%) vs 14 (20%) p=0.43, and CDI recurrence at day 60 9/43 (21%) vs 5/56 (9%) p=0.131. Conclusion A bundle of ASP interventions including prospective audit and feedback of CDI cases improved adherence to facility-specific CDI treatment guidelines.

Background and Purpose: Prompt identification of acute intracranial hemorrhage on CT is important. The goal of this study was to assess the impact of artificial intelligence software for prioritizing positive cases. Materials and Methods: Cases analyzed by Aidoc (Tel Aviv, Israel) software for triaging acute intracranial hemorrhage cases on non-contrast head CT were retrospectively reviewed. The scan view delay time was calculated as the difference between the time the study was completed on PACS and the time the study was first opened by a radiologist. The scan view delay was stratified by scan location, including emergency, inpatient, and outpatient. The scan view delay times for cases flagged as positive by the software were compared to those that were not flagged. Results: A total of 8723 scans were assessed by the software, including 6894 cases that were not flagged and 1829 cases that were flagged as positive. Although there was no statistically significant difference in the scan view time for emergency cases, there was a significantly lower scan view time for positive outpatient and inpatient cases flagged by the software versus negative cases, with a reduction of 604 min on average, 90% in the scan view delay (p-value < 0.0001) for outpatients, and a reduction of 38 min on average, and 10% in the scan view delay (p-value <= 0.01) for inpatients. Conclusion: The use of artificial intelligence triage software for acute intracranial hemorrhage on head CT scans is associated with a significantly shorter scan view delay for cases flagged as positive than cases not flagged among outpatients and inpatients at an academic medical center.
