38. Impact of Antimicrobial Stewardship Interventions on Adherence to Clostridioides difficile Treatment Guidelines

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.

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

AbstractObjectivesAntibiotic use varies widely between hospitals, but the influence of antimicrobial stewardship programs (ASPs) on this variability is not known. We aimed to determine the key structural and strategic aspects of ASPs associated with differences in risk-adjusted antibiotic utilization across facilities.DesignObservational study of acute-care hospitals in Ontario, CanadaMethodsA survey was sent to hospitals asking about both structural (8 elements) and strategic (32 elements) components of their ASP. Antibiotic use from hospital purchasing data was acquired for January 1 to December 31, 2014. Crude and adjusted defined daily doses per 1,000 patient days, accounting for hospital and aggregate patient characteristics, were calculated across facilities. Rate ratios (RR) of defined daily doses per 1,000 patient days were compared for hospitals with and without each antimicrobial stewardship element of interest.ResultsOf 127 eligible hospitals, 73 (57%) participated in the study. There was a 7-fold range in antibiotic use across these facilities (min, 253 defined daily doses per 1,000 patient days; max, 1,872 defined daily doses per 1,000 patient days). The presence of designated funding or resources for the ASP (RRadjusted, 0·87; 95% CI, 0·75–0·99), prospective audit and feedback (RRadjusted, 0·80; 95% CI, 0·67–0·96), and intravenous-to-oral conversion policies (RRadjusted, 0·79; 95% CI, 0·64–0·99) were associated with lower risk-adjusted antibiotic use.ConclusionsWide variability in antibiotic use across hospitals may be partially explained by both structural and strategic ASP elements. The presence of funding and resources, prospective audit and feedback, and intravenous-to-oral conversion should be considered priority elements of a robust ASP.

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: Inappropriate use of broad-spectrum antibiotics accelerates the development of drug resistance in nosocomial pathogens. In Malaysia, the National Antimicrobial Guidelines (NAG), along with the feedback from antimicrobial stewardship (AMS) teams, serves as an important guide for antibiotic use in hospitals. Objectives: This study aimed to determine the effectiveness of a prospective audit-and-feedback intervention in promoting the appropriate prescribing of third-generation cephalosporins and timely culture and sensitivity (C&S) testing in patients admitted to a neurosurgical ward. Method: In the pre-intervention phase, a ward pharmacist examined medical records of the patients receiving treatment with third-generation cephalosporins. The use of a cephalosporin was deemed to be appropriate only if it was in line with either the NAG or the recommendations made by the AMS team. The laboratory reports were also checked to see if the C&S testing was performed right before the first dose of a cephalosporin was given. The findings were subsequently presented and discussed in a 2-hour feedback session. The post-intervention audit was performed in the same manner as in the pre-intervention phase. Results: Seventy cases were studied in the pre- and post-intervention phases each. The proportion of cases with appropriate use of third-generation cephalosporin increased significantly from 77.1% (54/70) to 95.8% (67/70) following the intervention (p=0.001). The proportion of cases with a C&S test performed timely also increased significantly from 38.6% (27/70) to 58.6% (41/70) (p=0.018). Conclusion: The prospective audit-and-feedback intervention was effective in improving the appropriateness of the prescribing of third-generation cephalosporins and timely culture and sensitivity testing, indicating the antimicrobial stewardship strategy had produced a positive outcome.

Prospective Audit And Feedback

Background: Most hospitals have a basic infrastructure in place for antimicrobial stewardship programs (ASPs). Although this is a critical first step, we need to ensure that ASPs are working to implement effective evidence-based approaches nationally. In 2018, a group of leading antibiotic stewardship organizations met and identified specific, effective, and recommended ASP activities based on current scientific evidence and their experience (Baker et al, Joint Comm J Qual Pat Saf 2019;45:517–523). To determine the extent to which hospitals are currently implementing the recommended practices, we conducted an electronic questionnaire–based assessment. Methods: A 50-item questionnaire-based assessment was sent via QualtricsTM to the hospital’s designated ASP leader. The sample comprised 992 Joint Commission accredited hospitals. The practices of interest related to (1) development of facility-specific treatment guidelines, (2) measuring appropriate use and concordance of care with these guidelines, (3) engaging clinicians while the patient is on the unit, (4) diagnostic stewardship, (5) measurement of antimicrobial utilization data, and (6) measuring hospital-acquired Clostridioides difficile infection (CDI) rates. Sampling weights were used to adjust the results for nonresponse using R software. Results: In total, 288 hospitals completed the questionnaire. Small and nonteaching hospitals were significantly less likely to respond (p < 0.005, p=0.01 respectively), however there were no differences by healthcare system membership or urban/rural location. 49% of respondents had the specialist term ASP or infectious disease (ID) in their title. Most hospitals (93.1%) had developed facility-specific treatment guidelines for specific inpatient conditions, often community-acquired pneumonia (85%), sepsis (81%), UTI (75%), and SSTI (69%). However, only 37% had formally assessed compliance with 1 or more of these guidelines. Also, 83% reported having a process for prospective audit and feedback, of which 43% do this 4–5 days per week. Similarly, 49% reported that they review all antimicrobials ordered. Recommendations are commonly given by the ASP pharmacist (69%) via some combination of telephone (78%), face-to-face (69%), text message (54%), and/or EHR alert (36%). Overall, 66% of hospitals had procedures in place to prevent inappropriate diagnostic testing for C. difficile, and 39% of hospitals had similar policies for urine specimens. Furthermore, >80% were routinely measuring days of therapy and CDI rates. Conclusions: Most hospitals have facility-specific treatment guidelines and measure CDI and days of therapy. Practices for active engagement with frontline staff in prospective audit and feedback vary widely. Greater understanding of barriers to assessing adherence to hospitals’ treatment guidelines is critical to improving this practice.Funding: The Pew Charitable TrustsDisclosures: None

Bureau Of Prisons

Background: Fluoroquinolones are the perfect target for antimicrobial stewardship programs (ASPs) due to their broad-spectrum nature, poor safety profile, and frequent misuse. In April 2019, the Bureau of Prisons (BOP) created a national antimicrobial stewardship clinical pharmacist consultant program. One of the program’s main initiatives was to screen active fluoroquinolone prescriptions for appropriateness and work with providers to tailor therapy as needed. Since July 2019, pharmacist consultants have utilized a singular system-wide electronic health record (EHR) to conduct fluoroquinolone prospective audit and feedback targeting all BOP sites across the country. The objective was to assess the national impact of prospective audit and feedback on outpatient fluoroquinolone prescriptions utilizing pharmacist consultants and an integrated EHR. Method: Reviews were conducted in a federal correctional setting including 122 BOP sites with an average daily population of 167,308 inmates. The ASP consisted of 7 pharmacists, each assigned a region across the country. Consultant pharmacists were in charge of conducting daily fluoroquinolone reviews within 72 hours of the prescription being written, utilizing a singular system-wide EHR to gain remote access to newly prescribed prescriptions along with all other pertinent information (ie, clinical notes, patient profiles, laboratory, and radiology). Interventions were sent via e-mail. Total fluoroquinolone prescriptions per 1,000 inmates during the preintervention period (July 1, 2018, to September 30, 2018) were compared to the postintervention period (July 1, 2019, to September 30, 2019), after the development of the clinical consultant program. Data were also collected during the 3-month postintervention period to include total fluoroquinolone prescriptions reviewed, total recommendations sent, percentage of recommendations accepted, and intervention types. Results: In total, 833 fluoroquinolone prescriptions of 1, 264 total prescriptions written (66%)were reviewed over the 3-month postintervention period. In total,192 interventions were recommended (23%). Of the interventions recommended, 65 (34%) were accepted. The most common intervention was to stop therapy (41%), followed by changing antibiotic (37%), and shorten therapy duration (8%). Total outpatient fluoroquinolone prescriptions decreased by 1.5 prescriptions per 1,000 patients after the intervention. Conclusions: Pharmacist-driven prospective audit and feedback on a national scale utilizing a singular system-wide EHR resulted in an overall decrease in outpatient fluoroquinolone prescriptions over short period of time.Funding: NoneDisclosures: None

The Impact

Clostridioides difficile is the most common cause of healthcare-associated infection and gastroenteritis-associated death in the USA. Adherence to guideline recommendations for treatment of severe C. difficile infection (CDI) is associated with improved clinical success and reduced mortality. The purpose of this study was to determine whether implementation of a pharmacist-led antimicrobial stewardship program (ASP) CDI initiative improved adherence to CDI treatment guidelines and clinical outcomes. This was a single-center, retrospective, quasi-experimental study evaluating patients with CDI before and after implementation of an ASP initiative involving prospective audit and feedback in which guideline-driven treatment recommendations were communicated to treatment teams and documented in the electronic health record via pharmacy progress notes for all patients diagnosed with CDI. The primary endpoint was the proportion of patients treated with guideline adherent definitive regimens within 72 hours of CDI diagnosis. Secondary objectives were to evaluate the impact on clinical outcomes, including length of stay (LOS), infection-related LOS, 30-day readmission rates, and all-cause, in-hospital mortality. A total of 233 patients were evaluated. The proportion of patients on guideline adherent definitive CDI treatment regimen within 72 hours of diagnosis was significantly higher in the post-interventional group (pre: 42% vs post: 58%, p=0.02). No differences were observed in clinical outcomes or proportions of patients receiving laxatives, promotility agents, or proton pump inhibitors within 72 hours of diagnosis. Our findings demonstrate that a pharmacist-led stewardship initiative improved adherence to evidence-based practice guidelines for CDI treatment.
