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 In September 2018, pharmacy antimicrobial stewardship services were expanded to include weekends at Cleveland Clinic. Activities performed by antimicrobial stewardship (AMS) pharmacists on the weekend 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, the quasi-experimental study included data from 13 weekends before (9/2017 – November 2017) and after (9/2018 – November 2018) implementation of weekend services. The primary outcome was the number of reviews relating to each stewardship activity. Secondary outcomes were time to AMS opportunity resolution, time to escalation or de-escalation following PAF or RDT alert, time to resolution of other AMS-related opportunities, length of stay (LOS), and antimicrobial use outcomes. Patients were included in time to resolution outcomes if they had an RDT, ART, or select PAF review requiring intervention. Time to opportunity resolution was defined as the time from AMS alert to implementation of the recommendation in the electronic health record. Results During the post-intervention period 1261 reviews were conducted, averaging 97/weekend. This included 187 RDT, 432 PAF, 124 ART, 331 vancomycin dosing notes and 187 other. Inclusion criteria for time to resolution outcomes were met by 72 patients pre-intervention compared with 59 patients post. No significant differences were seen in baseline characteristics between groups with 43% of patients requiring ID consultation and 58% requiring ICU admission. The median time to opportunity resolution improved significantly overall (P < 0.01), with de-escalation (P = 0.03), and with time to other AMS opportunity (P = 0.01) (Figure 1). A numerical reduction was seen with time to escalation (P = 0.1). LOS was a median of 13 and 14 days pre- and post-intervention, respectively (P = 0.4). No differences were seen in antimicrobial use outcomes. Conclusion Presence of pharmacist-driven weekend AMS services significantly reduced time to resolution of AMS interventions. These data support the value of weekend AMS services. Disclosures All authors: No reported disclosures.

Abstract Background Multi-disciplinary engagement and education remain key measures for Antimicrobial Stewardship Programs (ASPs). Over 3 years, our ASP has undergone key changes to pre-authorization review, post-prescriptive activities, and core team members, coinciding with a 30% increase in stewardship interventions. The objectives of this study were to evaluate the familiarity of Nursing, Pharmacy and Prescribers at our academic medical center regarding ASP activities and services, as well as perceived impact on patient care and value. Secondary objectives were to determine what resources are currently utilized and areas for improvement. Methods Distinct surveys were distributed to three participant groups: Nurses, Pharmacists, and Prescribers (Housestaff, Advanced Practice Providers, and staff physicians). Questions were developed to assess familiarity, perceived value, and overall satisfaction with the ASP. Additional items included questions on the current use of ASP resources and educational engagement. Survey results were compared to a similar survey conducted 3 years amongst the same participant groups. Results The survey was delivered electronically to 3367 Prescribers, Nurses and Pharmacists. 403 responders completed the survey (208 Nurses, 181 Prescribers, and 18 Pharmacists). Familiarity was lowest amongst Nurses, but almost doubled compared to 2016 (Figure). Prescribers cited “restricted antibiotic approval”, “de-escalation”, and “alternative therapies relative to allergies” as the three most common interaction types, similar to 2016. ASP interactions continued to be rated “moderate” or “high” value (88.4% vs 89.15% in 2016), however, face-to-face interactions were preferred by only 4% of responders (unchanged compared to 2016). Prescribers also responded uncommon use of ASP online resources (20%) and clinical decision support tools (34%). 78% of responders expressed desire for increased ASP-related education. Conclusion As ASPs evolve, it is important to constantly evaluate impact and value, and identify areas for growth. Despite ASP familiarity being high and interactions valued, we need to further optimize ASP provided resources, clinical support tools, and educational offerings.

OBJECTIVETo assess antimicrobial utilization before and after a change in urine culture ordering practice in adult intensive care units (ICUs) whereby urine cultures were only performed when pyuria was detected.DESIGNQuasi-experimental studySETTINGA 700-bed academic medical centerPATIENTSPatients admitted to any adult ICUMETHODSAggregate data for all adult ICUs were obtained for population-level antimicrobial use (days of therapy [DOT]), urine cultures performed, and bacteriuria, all measured per 1,000 patient days before the intervention (January–December 2012) and after the intervention (January–December 2013). These data were compared using interrupted time series negative binomial regression. Randomly selected patient charts from the population of adult ICU patients with orders for urine culture in the presence of indwelling or recently removed urinary catheters were reviewed for demographic, clinical, and antimicrobial use characteristics, and pre- and post-intervention data were compared.RESULTSStatistically significant reductions were observed in aggregate monthly rates of urine cultures performed and bacteriuria detected but not in DOT. At the patient level, compared with the pre-intervention group (n=250), in the post-intervention group (n=250), fewer patients started a new antimicrobial therapy based on urine culture results (23% vs 41%, P=.002), but no difference in the mean total DOT was observed.CONCLUSIONA change in urine-culture ordering practice was associated with a decrease in the percentage of patients starting a new antimicrobial therapy based on the index urine-culture order but not in total duration of antimicrobial use in adult ICUs. Other drivers of antimicrobial use in ICU patients need to be evaluated by antimicrobial stewardship teams.Infect. Control Hosp. Epidemiol. 2016;37(4):448–454

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 &gt; 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 &gt; 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 Monitoring antimicrobial use and resistance are key components of initiatives to promote antimicrobial stewardship and prevent antimicrobial-resistant infections. In this surveillance study, we evaluated trends in resistance among healthcare-associated P. aeruginosa isolates and potential associations with antimicrobial consumption. Methods We established a retrospective cohort of P. aeruginosa isolates collected ≥48 hours after inpatient admission at a 1,300-bed academic medical center from July 1, 2013 to July 31, 2018. We included isolates from all clinical cultures and retained the first isolate for a patient encounter. We defined the multidrug-resistant (MDR) status in accordance with the phenotype definitions established by the Centers for Disease Control and Prevention. We calculated the monthly percentage of class-specific resistance and MDR status among isolates. We measured monthly antimicrobial consumption as days of therapy per 1,000 patient-days. To evaluate potential associations between identified trends in resistance and antimicrobial use, we constructed autoregressive integrated moving average models (ARIMA) with transfer functions. Results Of 1,897 isolates included in the analysis, 303 (16.0%) were classified as MDR P. aeruginosa. The rate of healthcare-associated P. aeruginosa infections and percent of MDR isolates remained stable over the five-year study period. However, we identified trends in resistance to specific antimicrobial classes: there was a significant increase in resistance to antipseudomonal carbapenems, while resistance to aminoglycosides and extended-spectrum cephalosporins decreased. Using the ARIMA modeling strategy, bivariable analyses of resistance and antimicrobial use revealed that carbapenem-resistant P. aeruginosa was positively correlated with the use of antipseudomonal carbapenems at a 1-month lag and ertapenem at a 5-month lag. Conclusion Risk assessments that only measure rates of MDR organisms may miss underlying trends in class resistance. Increasing carbapenem resistance despite a stable proportion of MDR isolates highlights a critical area for continued monitoring and antimicrobial stewardship initiatives targeted at carbapenem use in our hospital.
