Abstract Background The procalcitonin (PCT) assay is FDA-approved to help guide antimicrobial treatment of respiratory tract infections, however, conflicting data exist regarding its impact on shortening durations of therapy. The purpose of this study was to compare the impact of PCT to a targeted audit-and-feedback (TAF) strategy on prescribed antibiotic durations of therapy for community-acquired pneumonia (CAP). Methods A retrospective cohort study was conducted at two community teaching hospitals, one implementing PCT with routine audit-and-feedback and one implementing a TAF strategy recommending 5 days of therapy for uncomplicated CAP. The primary objective of this study was to compare the impact of PCT implementation to TAF implementation on durations of therapy prescribed for suspected CAP. Secondary objectives included comparing length of stay, 30-day readmission, mortality, and rates of Clostridioides difficile. Adult inpatients with an antibiotic ordered with an indication of pneumonia were eligible for inclusion. Those who were critically ill, immunocompromised, had concurrent infections, were made comfort care, discharged or expired within 48 hours were excluded. Results 311 patients were included (Pre-TAF n=80, Pre-PCT n=80, Post-TAF n=80, Post-PCT n=71). Average duration of therapy prescribed for CAP at baseline was similar between groups, Pre-TAF 7.0 days vs. Pre-PCT 7.8 days (p=0.1). After implementation of the respective interventions, there remained no difference in the average duration of therapy between groups, Post-TAF 5.5 days vs. Post-PCT 5.4 days (p=0.8). Both PCT and TAF strategies demonstrated significant improvement in prescribed durations for CAP between their respective Pre- and Post-intervention groups (p< 0.001 and p=0.002, respectively). The PCT protocol was followed 41% of the time in the Post-PCT group. There were no differences in readmission, mortality, or C. difficile between groups. Conclusion PCT and TAF were equally effective antimicrobial stewardship strategies in reducing total days of antibiotic therapy prescribed for CAP with no differences observed in patient outcomes.

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

Abstract Background Community-acquired pneumonia and healthcare-associated pneumonia are often treated with prolonged antibiotic therapy. Procalcitonin (PCT) has effectively and safely reduced antibiotic use for pneumonia in controlled studies. However, limited data exist regarding PCT guidance in real-world settings for management of pneumonia. Methods A retrospective, preintervention/postintervention quality improvement study was conducted to compare management for patients admitted with pneumonia before and after implementation of PCT guidance at two teaching hospitals in Pittsburgh, Pennsylvania. The preintervention period was March 1, 2014 through October 31, 2014, and the post-intervention period was March, 1 2015 through October 31, 2015. Results A total of 152 and 232 patients were included in the preintervention and postintervention cohorts, respectively. When compared with the preintervention group, the mean duration of therapy decreased (9.9 vs. 6.1 days; P < 0.001). More patients received an appropriate duration of 7 days or less (26.9% vs. 66.4%; P < 0.001). Additionally, mean hospital length of stay decreased in the postintervention group (4.9 vs. 3.5 days; P = 0.006). Pneumonia-related 30-day readmission rates (7.2% vs. 4.3%; P = 0.99) were unaffected. In the postintervention group, patients with PCT levels < 0.25 µg/l received shorter mean duration of therapy compared with patients with levels >0.25 µg/l (8.0 vs. 4.6 days; P < 0.001) as well as reduced hospital length of stay (3.9 vs. 3.2 days; P = 0.02). Conclusion In this real-world practice study, PCT guidance led to shorter durations of total antibiotic therapy and abridged inpatient length of stay without affecting hospital re-admissions.

Abstract Background S. aureus, including MRSA, is a common colonizer of the nares. Recent data have shown that a negative MRSA nares screen by PCR has a negative predictive value of 98%. This implies that the absence of colonization can significantly reduce empiric vancomycin utilization. This study aimed to determine the utilization of MRSA nares screening on patients receiving vancomycin for respiratory tract infections (RTI) following the addition of the screen to the institutional RTI management guidelines. Methods This was a retrospective chart review of adult inpatients presenting to two community-teaching hospitals who were prescribed vancomycin for the treatment of RTIs. Patients were divided into pre-guideline (Jan-Feb 2019), post-guideline 1 (Jan-Feb 2020), and post-guideline 2 (Jan-Feb 2021) groups. The primary endpoint was the difference in percent of vancomycin orders discontinued within 24 hours of a negative screen. Secondary endpoints included the percent of screens ordered, re-initiation of vancomycin within seven days for RTI, and total vancomycin days of therapy (DOT) per 1000 patient days (PD). Results Of 493 vancomycin orders screened, 100 orders in each arm were analyzed. There was an absolute increase of 20.6% in vancomycin orders discontinued within 24 hours of a negative screen between the pre-guideline and post-guideline 2 groups (59.1% vs. 79.7%, p = 0.0177). When compared to the pre-guideline group, utilization of the screen increased by 15% in the post-guideline 1 group (48% vs. 63%, p = 0.0328) and 26% in the post-guideline 2 group (48% vs. 74%, p = 0.000164). There was no difference in re-initiation of vancomycin. A statistically significant reduction in total vancomycin DOT/1000PD from the pre-guideline to the post-guideline 1 and 2 groups (66 to 63 to 60, respectively) was also observed. Conclusion The addition of the MRSA nares screen to the institutional RTI guidelines increased utilization of the test and demonstrated a reduction in vancomycin utilization. With an increase in education, prospective audit and feedback, and prescriber comfort with the use of the MRSA nares screen in the post-guideline 2 group, there was significant improvement in MRSA nares screen utilization, vancomycin discontinuation after a negative screen, and vancomycin utilization.

Abstract Background Minimal literature exists to demonstrate the quantitative impact of bedside nurses in antimicrobial stewardship (AMS). We initiated bedside nurse-driven AMS and infection prevention (AMS/IP) rounds on three inpatient telemetry units of a community regional medical center. Rounds were nurse-driven, involved an infectious diseases (ID) pharmacist and infection preventionist, and were designed to complement traditional ID pharmacist and ID physician AMS rounds. Rounds were focused on use of antibiotics, urinary catheters (UCs), and central venous catheters (CVCs). Recommendations from rounds were communicated by the bedside nurse either directly to providers or to the ID pharmacist and ID physician for intervention. Methods This was an observational, multiple-group, quasi-experimental study conducted over 3.5 years (July 2015 to December 2018) to characterize the impact of bedside nurse-driven AMS/IP rounds on antibiotic, urinary catheter and CVC use, hospital-onset C. difficile infection (CDI), catheter-associated urinary tract infections (CAUTI), and central line-associated bloodstream infections (CLABSI). Outcomes were assessed in two cohorts based on time of AMS/IP rounds implementation (Cohort 1 implemented on one telemetry unit in July 2016, Cohort 2 implemented in two telemetry units in January 2018). Results A total of 2,273 patient therapy reviews occurred (Cohort 1: 1,736; Cohort 2: 537). Of these reviews, 1,209 (53%) were antibiotics, 879 (39%) were urinary catheters, and 185 (8%) were CVCs. Pre- vs. post-intervention, significant reductions were observed in both cohorts for mean monthly antibiotic days of therapy per 1,000 patient-days (Cohort 1: 791 vs. 688, P < 0.001; Cohort 2: 615 vs. 492, P < 0.001), UC days per patient day (Cohort 1: 0.25 vs. 0.16, P < 0.001; Cohort 2: 0.19 vs. 0.14, P < 0.001), CVC days per patient day (Cohort 1: 0.15 vs. 0.11, = 0.002; Cohort 2: 0.09 vs. 0.07, p = 0.005), and CDI per 10,000 patient-days (Cohort 1: 17.8 vs. 7.1, p = 0.035; Cohort 2: 19.1 vs. 5.4, p = 0.003). Numerical reductions were observed in CAUTI and CLABSI per 10,000 patient-days. Conclusion Bedside nurses can improve AMS and IP outcomes in a scalable fashion when supported by an interdisciplinary AMS/IP team and are complimentary to traditional AMS and IP practices.

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

Abstract Background To meet the core elements required for antimicrobial stewardship programs, our institution implemented a pharmacy-led antibiotic timeout (ATO) process in 2017 and a multidisciplinary ATO process in 2019. An antibiotic timeout is a discussion and review of the need for ongoing empirical antibiotics 2-4 days after initiation. This study sought to evaluate both the multidisciplinary ATO and the pharmacy-led ATO in a pediatric population, compare the impact of each intervention on antibiotic days of therapy (DOT) to a pre-intervention group without an ATO, and to then compare the impact of the pharmacy-led ATO versus multidisciplinary ATO on antibiotic days of therapy (DOT). Methods This was a retrospective, pre-post, quasi-experimental study of pediatric patients comparing antibiotic DOT prior to ATO implementation (pre-ATO), during the pharmacy-led ATO (pharm-ATO), and during the multidisciplinary ATO (multi-ATO). The pre-ATO group was a patient sample from February-September 2016, prior to the initiation of a formal ATO. The pharmacy-led ATO was implemented from February-September 2018. This was followed by a multidisciplinary ATO led by pediatric residents and nurses from February-September 2019. Both the pharm-ATO and the multi-ATO were implemented as an active non-interruptive alert added to the electronic health record patient list. This alert triggered when new antibiotics had been administered to the patient for 48 hours, at which time, the responsible clinician would discuss the antibiotic and document their decision via the alert workspace. Pediatric patients receiving IV or PO antibiotics administered for at least 48 hours were included. The primary outcome was DOT. Secondary outcomes included length of stay (LOS) and mortality. Results 1284 unique antibiotic orders (n= 572 patients) were reviewed in the pre-ATO group, 868 (n= 323 patients) in the pharm-ATO and 949 (n= 305 patients) in the multi-ATO groups. Average DOT was not significantly different pre vs post intervention for either methodology (Table 1). Mortality was similar between groups, but LOS was longer for both intervention groups (Table 1). Impact of an ATO on DOT, Mortality and LOS Conclusion An ATO had no impact on average antibiotic DOT in a pediatric population, regardless of the ATO methodology.

Background: The Infectious Diseases Society of America released updated community-acquired pneumonia (CAP) guidelines in October 2019. One of the recommendations, with a low quality of supporting evidence, is the standard administration of antibiotics in adult patients with influenza and radiographic evidence of pneumonia. Procalcitonin (PCT) is not endorsed as a strategy to withhold antibiotic therapy, but it could be used to de-escalate appropriate patients after 48–72 hours. Radiographic findings are not indicative of the etiology of pneumonia. Prescribing antibiotics for all influenza-positive patients with an infiltrate has significant implications for stewardship. Therefore, we reviewed hospitalized, influenza-positive patients at our institution during the 2018–2019 season, and we sought to assess the impact of an abnormal chest x-ray (CXR) and PCT on antibiotic prescribing and outcomes. Methods: We conducted a retrospective chart review of all influenza-positive admissions at 2 urban, community-based, teaching hospitals. Demographic data, vaccination status, PCT levels, CXR findings, and treatment regimens were reviewed. The primary outcome was the difference in receipt of antibiotics between patients with a negative (<0.25 ng/mL) and positive PCT. Secondary outcomes included the impact of CXR result on antibiotic prescribing, duration, 30-day readmission, and 90-day mortality. Results: We reviewed the medical records of 117 patients; 43 (36.7%) received antibiotics. The vaccination rate was 36.7%. Also, 11% of patients required intensive care unit (ICU) admission and 84% received antibiotics. Moreover, 109 patients had a CXR: 61 (55.9%) were negative, 29 (26.6%) indeterminate, and 19 (17.4%) positive per radiologist interpretation. Patients with a positive PCT (OR, 12.7; 95% CI, 3.43–60.98; P < .0007) and an abnormal CXR (OR, 7.4; 95% CI, 2.9–20.1; P = .000003) were more likely to receive antibiotics. There was no significant difference in 30-day readmission (11.6% vs 13.5%; OR, 0.89; 95% CI, 0.21–3.08; P = 1) and 90-day mortality (11.6% vs 5.4%; OR, 2.37; 95% CI, 0.48–12.75; P = .28) between those that received antibiotics and those that did not, respectively. Furthermore, 30 patients (62.5%) with an abnormal CXR received antibiotics and 21 (43.7%) had negative PCT. There was no difference in 30-day readmission or 90-day mortality between those that did and did not receive antibiotics. Conclusions: Utilization of PCT allowed selective prescribing of antibiotics without impacting readmission or mortality. Antibiotics should be initiated for critically ill patients and based on clinical judgement, rather than for all influenza-positive patients with CXR abnormalities.Funding: NoneDisclosures: None

Abstract Background Implementation of the Accelerate PhenoTM Gram-negative platform (RDT) paired with antimicrobial stewardship program (ASP) intervention projects to improve time to institutional-preferred antimicrobial therapy (IPT) for Gram-negative bacilli (GNB) bloodstream infections (BSIs). However, few data describe the impact of discrepant RDT results from standard of care (SOC) methods on antimicrobial prescribing. Methods A single-center, pre-/post-intervention study of consecutive, nonduplicate blood cultures for adult inpatients with GNB BSI following combined RDT + ASP intervention was performed. The primary outcome was time to IPT. An a priori definition of IPT was utilized to limit bias and to allow for an assessment of the impact of discrepant RDT results with the SOC reference standard. Results Five hundred fourteen patients (PRE 264; POST 250) were included. Median time to antimicrobial susceptibility testing (AST) results decreased 29.4 hours (P &lt; .001) post-intervention, and median time to IPT was reduced by 21.2 hours (P &lt; .001). Utilization (days of therapy [DOTs]/1000 days present) of broad-spectrum agents decreased (PRE 655.2 vs POST 585.8; P = .043) and narrow-spectrum beta-lactams increased (69.1 vs 141.7; P &lt; .001). Discrepant results occurred in 69/250 (28%) post-intervention episodes, resulting in incorrect ASP recommendations in 10/69 (14%). No differences in clinical outcomes were observed. Conclusions While implementation of a phenotypic RDT + ASP can improve time to IPT, close coordination with Clinical Microbiology and continued ASP follow up are needed to optimize therapy. Although uncommon, the potential for erroneous ASP recommendations to de-escalate to inactive therapy following RDT results warrants further investigation.

Background: Antibiotic overuse contributes to antibiotic resistance and unnecessary adverse drug effects. Antibiotic stewardship interventions have primarily focused on acute-care settings. Most antibiotic use, however, occurs in outpatients with acute respiratory tract infections such as pharyngitis. The electronic health record (EHR) might provide an effective and efficient tool for outpatient antibiotic stewardship. We aimed to develop and validate an electronic algorithm to identify inappropriate antibiotic use for pediatric outpatients with pharyngitis. Methods: This study was conducted within the Children’s Hospital of Philadelphia (CHOP) Care Network, including 31 pediatric primary care practices and 3 urgent care centers with a shared EHR serving >250,000 children. We used International Classification of Diseases, Tenth Revision (ICD-10) codes to identify encounters for pharyngitis at any CHOP practice from March 15, 2017, to March 14, 2018, excluding those with concurrent infections (eg, otitis media, sinusitis), immunocompromising conditions, or other comorbidities that might influence the need for antibiotics. We randomly selected 450 features for detailed chart abstraction assessing patient demographics as well as practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for evaluating the electronic algorithm. Criteria for appropriate use included streptococcal testing, use of penicillin or amoxicillin (absent β-lactam allergy), and a 10-day duration of therapy. Results: In 450 patients, the median age was 8.4 years (IQR, 5.5–9.0) and 54% were women. On chart review, 149 patients (33%) received an antibiotic, of whom 126 had a positive rapid strep result. Thus, based on chart review, 23 subjects (5%) diagnosed with pharyngitis received antibiotics inappropriately. Amoxicillin or penicillin was prescribed for 100 of the 126 children (79%) with a positive rapid strep test. Of the 126 children with a positive test, 114 (90%) received the correct antibiotic: amoxicillin, penicillin, or an appropriate alternative antibiotic due to b-lactam allergy. Duration of treatment was correct for all 126 children. Using the electronic algorithm, the proportion of inappropriate prescribing was 28 of 450 (6%). The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were sensitivity (99%, 422 of 427); specificity (100%, 23 of 23); positive predictive value (82%, 23 of 28); and negative predictive value (100%, 422 of 422). Conclusions: For children with pharyngitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. Future work should validate this approach in other settings and develop and evaluate the impact of an audit and feedback intervention based on this tool.Funding: NoneDisclosures: None

Introduction.Antimicrobial stewardship programs are being implemented in health care to reduce inappropriate antimicrobial use, adverse events, Clostridium difficile infection, and antimicrobial resistance. There is no standardized approach to evaluate the impact of these programs.Objective.To use a structured panel process to define quality improvement metrics for evaluating antimicrobial stewardship programs in hospital settings that also have the potential to be used as part of public reporting efforts.Design.A multiphase modified Delphi technique.Setting.Paper-based survey supplemented with a 1-day consensus meeting.Participants.A 10-member expert panel from Canada and the United States was assembled to evaluate indicators for relevance, effectiveness, and the potential to aid quality improvement efforts.Results.There were a total of 5 final metrics selected by the panel: (1) days of therapy per 1000 patient-days; (2) number of patients with specific organisms that are drug resistant; (3) mortality related to antimicrobial-resistant organisms; (4) conservable days of therapy among patients with community-acquired pneumonia (CAP), skin and soft-tissue infections (SSTI), or sepsis and bloodstream infections (BSI); and (5) unplanned hospital readmission within 30 days after discharge from the hospital in which the most responsible diagnosis was one of CAP, SSTI, sepsis or BSI. The first and second indicators were also identified as useful for accountability purposes, such as public reporting.Conclusion.We have successfully identified 2 measures for public reporting purposes and 5 measures that can be used internally in healthcare settings as quality indicators. These indicators can be implemented across diverse healthcare systems to enable ongoing evaluation of antimicrobial stewardship programs and complement efforts for improved patient safety.
