AbstractObjective:To evaluate whether incorporating mandatory prior authorization for Clostridioides difficile testing into antimicrobial stewardship pharmacist workflow could reduce testing in patients with alternative etiologies for diarrhea.Design:Single center, quasi-experimental before-and-after study.Setting:Tertiary-care, academic medical center in Ann Arbor, Michigan.Patients:Adult and pediatric patients admitted between September 11, 2019 and December 10, 2019 were included if they had an order placed for 1 of the following: (1) C. difficile enzyme immunoassay (EIA) in patients hospitalized >72 hours and received laxatives, oral contrast, or initiated tube feeds within the prior 48 hours, (2) repeat molecular multiplex gastrointestinal pathogen panel (GIPAN) testing, or (3) GIPAN testing in patients hospitalized >72 hours.Intervention:A best-practice alert prompting prior authorization by the antimicrobial stewardship program (ASP) for EIA or GIPAN testing was implemented. Approval required the provider to page the ASP pharmacist and discuss rationale for testing. The provider could not proceed with the order if ASP approval was not obtained.Results:An average of 2.5 requests per day were received over the 3-month intervention period. The weekly rate of EIA and GIPAN orders per 1,000 patient days decreased significantly from 6.05 ± 0.94 to 4.87 ± 0.78 (IRR, 0.72; 95% CI, 0.56–0.93; P = .010) and from 1.72 ± 0.37 to 0.89 ± 0.29 (IRR, 0.53; 95% CI, 0.37–0.77; P = .001), respectively.Conclusions:We identified an efficient, effective C. difficile and GIPAN diagnostic stewardship approval model.

Abstract Background The University of Minnesota Medical Center (UMMC) is a tertiary care facility, which has had a comprehensive antimicrobial stewardship program (ASP) for 12 years. Methods The antimicrobial stewardship team is comprised of a full-time PharmD and ID staff physicians. Recommendations are placed in the electronic medical record as a progress note. Verbal recommendations may also be made. Results There was a downward trend in Hospital-acquired (HA) C. difficile diarrhea from 2007 to 2014 from 1.2 to 0.5/1000 patient-days (pt day). Rates appear stable from 2014 to 2019 with adjustment for change to NHSN lab-based CDI surveillance (Figure 1). From 2009 to 2019 a decrease was seen in VRE hospital-acquired infections (HAI) from 0.53 to 0.21/1,000 patient-days and in MRSA HAIs from 0.2 to 0.14/1,000 patient-days. Newly acquired ESBL HAIs have remained relatively stable from 2009 to 2019 at 0.09 to 0.05/1,000 patient-days. CRE HAIs are low but stable rates at 0.02/1,000 patient-days (Figure 2). We track antimicrobial utilization for internal and national reporting (starting in July 2017). A SAAR for all Antibacterial agents (ICUs, wards, and oncology units) of 1.33 in 2018. Our top four agents average DOT; piperacillin/tazobactam (66.81), cefepime (34.40), oral levofloxacin (23.56) and intravenous meropenem (21.49). We demonstrate lower average DOT for our restricted antimicrobials (206.21) as compared with our nonrestricted antimicrobials (236.74) (Figure 3). Cost savings continued from year to year. After adjusting for inflation annually, our expected costs ($84.08) compared with actual costs ($40.12 ytd 2019), demonstrates effective cost management of antimicrobial agents. (Figure 4) Conclusion We observed a decrease in HAIs VRE and C. difficile infections after 3 years of operation, and MRSA after 5 years. This downward trend has continued. ESBL HAIs remain relatively stable and CRE are stable at low rates but remain emerging HAIs of concern. We are now focusing efforts on limiting unneeded fluoroquinolone and carbapenem use. We continue to analyze our SAAR data and internal DOT data to identify areas of opportunity to improve antimicrobial use. The ASP outcomes have continued to cost justify ongoing efforts. The effects of the program and the Infection Prevention Department appear to be synergistic. Disclosures All authors: No reported disclosures.

Background.An antimicrobial stewardship program was fully implemented at the University of Maryland Medical Center in July 2001 (beginning of fiscal year [FY] 2002). Essential to the program was an antimicrobial monitoring team (AMT) consisting of an infectious diseases-trained clinical pharmacist and a part-time infectious diseases physician that provided real-time monitoring of antimicrobial orders and active intervention and education when necessary. The program continued for 7 years and was terminated in order to use the resources to increase infectious diseases consults throughout the medical center as an alternative mode of stewardship.Design.A descriptive cost analysis before, during, and after the program.Patients/Setting.A large tertiary care teaching medical center.Methods.Monitoring the utilization (dispensing) costs of the antimicrobial agents quarterly for each FY.Results.The utilization costs decreased from $44,181 per 1,000 patient-days at baseline prior to the full implementation of the program (FY 2001) to $23,933 (a 45.8% decrease) by the end of the program (FY 2008). There was a reduction of approximately $3 million within the first 3 years, much of which was the result of a decrease in the use of antifungal agents in the cancer center. After the program was discontinued at the end of FY 2008, antimicrobial costs increased from $23,933 to $31,653 per 1,000 patient-days, a 32.3% increase within 2 years that is equivalent to a $2 million increase for the medical center, mostly in the antibacterial category.Conclusions.The antimicrobial stewardship program, using an antimicrobial monitoring team, was extremely cost effective over this 7-year period.

Prior Approval

Objective. Prior-approval antimicrobial stewardship programs (ASPs) improve patient outcomes and decrease antimicrobial resistance. These benefits would be limited if physicians circumvented ASP efforts. We evaluated whether prescribers wait until after the prior-approval period to order restricted antimicrobial therapy that is in conflict with guidelines or unnecessary. Design. A cross-sectional study design and a retrospective cohort study design. Setting. A tertiary care, academic medical center with a prior-approval ASP that was active between 8 AM and 10 PM. Methods. We evaluated whether there was an increase in the proportion of orders for antimicrobial therapy that involve restricted (vs nonrestricted) antimicrobials during the first hour that the ASP is inactive (ie, the first hour that prior approval is not required), compared with the remainder of the day. We also evaluated whether restricted antimicrobial therapy ordered during this first hour is less likely to be continued when the ASP becomes active the next day, compared with that ordered during the preceding hour. Results. A greater proportion of the antimicrobial therapy orders placed between 10:00 PM and 10:59 PM were for restricted agents, compared with orders placed during other periods (57.0% vs 49.9%; P = .02). Surgical patients for whom antimicrobial therapy orders were placed between 10:00 PM and 10:59 PM were less likely to have that antimicrobial therapy continued, compared with patients whose therapy was ordered between 9:00 PM and 9:59 PM (60.0% vs 98.1%; P <.001). Nonsurgical patients whose therapy orders were placed between 10:00PM and 10:59 PM were also less likely to have the ordered antimicrobial therapy continued, compared with patients whose therapy was ordered between 9:00 PM and 9:59 PM (70.8% vs 84.2%; P = .01). Conclusion. Physicians avoid having to obtain prior approval for therapy involving restricted antimicrobials by waiting until restrictions are no longer active to place orders. Compared with restricted antimicrobial therapy ordered when the ASP is active, these courses of therapy are less often continued by the ASP, suggesting that they are more likely to be in conflict with guidelines or unnecessary.

AbstractObjective:To evaluate the impact of a hard stop in the electronic health record (EHR) on inappropriate gastrointestinal pathogen panel testing (GIPP).Design:We used a quasi-experimental study to evaluate testing before and after the implementation of an EHR alert to stop inappropriate GIPP ordering.Setting:Midwest academic medical center.Participants:Hospitalized patients with diarrhea for which GIPP testing was ordered, between January 2016 through March 2017 (period 1) and April 2017 through June 2018 (period 2).Intervention:A hard stop in the EHR prevented clinicians from ordering a GIPP more than once per admission or in patients hospitalized for >72 hours.Results:During period 1, 1,587 GIPP tests were ordered over 212,212 patient days, at a rate of 7.48 per 1,000 patient days. In period 2, 1,165 GIPP tests were ordered over 222,343 patient days, at a rate of 5.24 per 1,000 patient days. The Poisson model estimated a 30% reduction in total GIPP ordering rates between the 2 periods (relative risk, 0.70; 95% confidence interval [CI], 0.63–0.78; P < .001). The rate of inappropriate tests ordered decreased from 21.5% to 4.9% between the 2 periods (P < .001). The total savings calculated factoring only GIPP orders that triggered the hard stop was ∼$67,000, with potential savings of $168,000 when factoring silent best-practice alert data.Conclusions:A simple hard stop alert in the EHR resulted in significant reduction of inappropriate GIPP testing, which was associated with significant cost savings. Clinicians can practice diagnostic stewardship by avoiding ordering this test more than once per admission or in patients hospitalized >72 hours.

Stewardship Program

The Centers for Medicare and Medicaid Services (CMS) have mandated that acute care and critical access hospitals implement an Antimicrobial stewardship (AMS) program. This manuscript describes the process that was implemented to ensure CMS compliance for AMS, across a 14-member health system (eight community hospitals, five critical access hospitals, and an academic medical center) in the Omaha metro area, and surrounding cities. The addition of the AMS program to the 14-member health system increased personnel, with a 0.5 full-time equivalent (FTE) infectious diseases (ID) physician, and 2.5 FTE infectious diseases trained clinical pharmacists to support daily AMS activities. Clinical decision support software had previously been implemented across the health system, which was also key to the success of the program. Overall, in its first year, the AMS program demonstrated a $1.2 million normalized reduction (21% total reduction in antimicrobial purchases) in antimicrobial expenses. The ability to review charts daily for antimicrobial optimization with ID pharmacist and physician support, identify facility specific needs and opportunities, and to collect available data endpoints to determine program effectiveness helped to ensure the success of the program.

Objective.Evaluate antimicrobial stewardship interventions targeted to reduce highly active antiretroviral therapy (HAART)– or opportunistic infection (Ol)–related medication errors and increase error resolution.Design.Retrospective before-after study.Setting.Academic medical center.Patients.Inpatients who were prescribed antiretroviral therapy before the intervention (January 1, 2011, to October 31, 2011) and after the intervention (July 1, 2012, to December 31, 2012). Patients treated with lamivudine or tenofovir monotherapy for hepatitis B were excluded.Methods.Antimicrobial stewardship interventions included education, modification of electronic medication records, collaboration with the infectious diseases (ID) department, and prospective audit and review of HAART and OI regimens by an ID clinical pharmacist.Results.Data for 162 admissions from the preintervention period and 110 admissions from the postintervention period were included. The number of admissions with a medication error was significantly reduced after the intervention (81 [50%] of 162 admissions vs 37 (34%) of 110 admissions; P < .00)1. A total of 124 errors occurred in the preintervention group (mean no. of errors, 1.5 per admission), and 43 errors occurred in the postintervention group (mean no. of errors, 1.2 per admission). The most common error types were major drug interactions and dosing in the preintervention group and renal adjustment and OI-related errors in the postintervention group. A significantly higher error resolution rate was observed in the postintervention group (36% vs 74%; P < .001). After adjustment for potential confounders with logistic regression, admission in the postintervention group was independently associated with fewer medication errors (odds ratio, 0.4 [95% confidence interval, 0.24-0.77]; P = .005). Overall, presence of an ID consultant demonstrated a higher error resolution rate (32% without a consultation vs 68% with a consultation; P = .002).Conclusions.Multifaceted, multidisciplinary stewardship efforts reduced the rate and increased the overall resolution of HAART-related medication errors.

(See the commentary by Van Schooneveld and Rupp, on pages1100–1102.)ObjectiveAlthough prior authorization and prospective audit with feedback are both effective antimicrobial stewardship program (ASP) strategies, the relative impact of these approaches remains unclear. We compared these core ASP strategies at an academic medical center.DesignQuasi-experimental study.MethodsWe compared antimicrobial use during the 24 months before and after implementation of an ASP strategy change. The ASP used prior authorization alone during the preintervention period, June 2007 through May 2009. In June 2009, many antimicrobials were unrestricted and prospective audit was implemented for cefepime, piperacillin/tazobactam, and vancomycin, marking the start of the postintervention period, July 2009 through June 2011. All adult inpatients who received more than or equal to 1 dose of an antimicrobial were included. The primary end point was antimicrobial consumption in days of therapy per 1,000 patient-days (DOT/1,000-PD). Secondary end points included length of stay (LOS).ResultsIn total, 55,336 patients were included (29,660 preintervention and 25,676 postintervention). During the preintervention period, both total systemic antimicrobial use (−9.75 DOT/1,000-PD per month) and broad-spectrum anti-gram-negative antimicrobial use (−4.00 DOT/1,000-PD) declined. After the introduction of prospective audit with feedback, however, both total antimicrobial use (+9.65 DOT/1,000-PD per month; P < .001) and broad-spectrum anti-gram-negative antimicrobial use (+4.80 DOT/1,000-PD per month; P < .001) increased significantly. Use of cefepime and piperacillin/tazobactam both significantly increased after the intervention (P = .03). Hospital LOS and LOS after first antimicrobial dose also significantly increased after the intervention (P = .016 and .004, respectively).ConclusionsSignificant increases in antimicrobial consumption and LOS were observed after the change in ASP strategy.Infect Control Hosp Epidemiol 2014;35(9):1092-1099

Objective The primary objectives were to evaluate the prescriber acceptance rate of Antimicrobial Stewardship Program (ASP) pharmacist recommendation to de-escalate/discontinue meropenem, and estimate the difference in duration of meropenem therapy. The secondary objective was to determine incidence of adverse events in the two groups. Methods It was a retrospective study. All patients admitted to Gwinnett Medical Center and receiving meropenem from January–November 2015 were included in the study. Exclusion criteria were: patients admitted to intensive care unit, one-time dose, infectious disease consultation, and age <18 years. Electronic medical records were reviewed for data collection. The control group consisted of patients from January–July 2015 when there was no ASP pharmacist. The intervention group consisted of patients from August–November 2015 during which period the ASP pharmacist recommended de-escalation/discontinuation of meropenem based on culture and sensitivity results. Results A total of 41 patients were studied, 21 in the control group and 20 in the intervention group. There was no significant difference in baseline characteristics in the two groups and in terms of prior hospitalization or antibiotic use (within 90 days) and documented or suspected MDRO infection at the time of admission. De-escalation/discontinuation was suggested in 16/20 patients in the intervention group (80%), and intervention was accepted in 68%. The mean duration of therapy was significantly decreased in the intervention group (5.6 days vs. 8.1 days, p =0.0175). Two patients had thrombocytopenia (unrelated to meropenem), and none of the patients had seizure. Conclusion Targeted antibiotic review is an effective ASP strategy, which significantly decreases the duration of meropenem therapy.

Introduction: Thrombolytic window for acute ischemic stroke is brief and crucial. The AHA/ASA Target: Stroke Best Practice Strategies (TSBPS) aim to help hospitals improve thrombolysis door-to-needle (DTN) time. We assessed long-term efficacy of TSBPS to reduce DTN in a tertiary care hospital. Methods: We initiated a quality improvement program across one regional academic medical center (1,550 beds, 900 annual stroke admissions) that serves a multi-ethnic population by establishing a multidisciplinary DTN committee to assess causes of delayed DTN and implement focused TSBPS. Strategies included stroke team pre-admission notification, direct transfer to CT scanner, storing and administering IV rt-PA at CT scanner, and immediate stakeholder feedback. Door-to-CT, DTN, CT to IV rt-PA and door-to-groin (DTG) times were analyzed prospectively in consecutive IV rt-PA treated patients over 27 months pre-implementation and 13 months post-implementation. Results: A total of 148 patients were included in the pre-implementation and 126 patients in the post-implementation group. The two groups had similar demographics, comorbidities, anticoagulation status, pre-thrombolysis hypertension treatment, stroke severity (median NIHSS 11 (6-18) vs. 11 (5-17), p= 0.483), arrival by EMS (96% vs. 97%, p=0.708), and arrival after hours. Post implementation, reductions in treatment times were observed for median DTN (IQR) 59 (52-80) to 28.5 (20-41) min (p<0.001), door-to-CT time 17 (14-21) to 16 (12-19) min (p=0.016), CT-to-IV rt-PA time 43 (31-59) to 13 (6-23) min (p<0.001), and DTG time 164 (136-188) min (n=37) to 86 (63-103) min (n=51) (p<0.001). Overall monthly IV r-tPA administration increased post-implementation (5.5 vs. 9.8, p<0.001). Rate of symptomatic intracranial hemorrhage (2.7% vs. 3.2%, p=0.817) and treatment of stroke mimics (9% vs. 13%, p=0.311) were similar pre- and post-implementation. Conclusions: In this study, delay in IV rt-PA administration was predominantly related to prolonged CT to IVrt-PA time. DTN committee implementation is a simple, low-cost intervention, that significantly reduced DTN and DTG with persistent effect and no increase in symptomatic intracranial hemorrhage or stroke mimic treatment rate.
