Abstract Background According to the WHO, carbapenems and fluoroquinolones (FQ) should be key targets for stewardship programs. Methods A multifaceted antimicrobial stewardship program (ASP) was implemented in July 2018 at a 160-bed tertiary care center serving the tristate area of Iowa, South Dakota and Nebraska. Carbapenem and FQ use during pre-ASP intervention period (P1: 12/01/2016-6/30/2018) was compared with ASP-intervention period (P2: 07/01/2018-1/31/2020). ASP interventions included: stewardship educational pearls in monthly physician newsletters; educational posters in provider areas; suppression of carbapenem results on microbiology susceptibility reports; provider counseling for appropriate ordering; creating carbapenem alternative alert in order-entry software; removing FQ and carbapenems from order-sets where appropriate; default antibiotic stop dates changed to 7 days in EMR (Epic); adverse effects warning fired as an alert when ordering FQ. Pharmacist interventions: procalcitonin protocol allowing pharmacists to reorder follow-up procalcitonin and make recommendations to discontinue therapy where appropriate. Results FQ use declined significantly from a mean of 133 days of therapy (DOT) per 1000 days to 46 DOT per 1000 patient days during P2 (p< 0.0001). Carbapenem use declined significantly from a mean of 65 DOT per 1000 patient days during P1 to 9 DOT per 1000 patient days in P2 (p< 0.001). All hospital units showed a significant decrease in use, with intensive care units (ICUs) noting 56% reduction (p< 0.00001) during P2 compared to P1. During P2, 55% of orders for carbapenems and FQ during P2 were found to be appropriate compared to 39% in P1 (p< 0.0001). Sensitivity profile for Pseudomonas aeruginosa improved from 86% carbapenem sensitivity during P1 to 89% in P2 and no Carbapenem-Resistant Enterobacteriaceae isolates were identified during the study period; FQ sensitivity remained stable at 81%. Cost savings of &757 per 1000 patient days were recognized in P2 as a result of reduced use. Conclusion With ASP and pharmacist interventions, a significant decline in total utilization of carbapenem and FQ, considerable cost savings and an increase in proportion of appropriate use were observed.

Abstract Background Per World Health Organization, carbapenems should be key targets for antibiotic stewardship programs. Methods A multifaceted antimicrobial stewardship program (ASP) was implemented in January 2018 at a 160-bed tertiary care center serving the tristate area of Iowa, South Dakota and Nebraska. Carbapenem use during pre ASP intervention period (P1: 07/01/2016-12/31/2017) was compared with ASP intervention period (P2: 01/01/2018-06/30/2019). ASP interventions included: providing educational pearls in monthly physician newsletter; educational posters in high-traffic provider areas; suppression of carbapenem results on microbiology susceptibility reports; distributing monthly carbapenem use data to providers; provider counseling for appropriate ordering; creating carbapenem alternative alert in order-entry software; generating pharmacy decision-support software algorithms to aid in identifying intervention opportunities; removing carbapenems from order-sets where appropriate. Additional ASP pharmacist interventions: limiting double antibiotic coverage for pseudomonas/anaerobes; de-escalation recommendations. Results Carbapenem use declined significantly from a mean of 64.81 days of therapy (DOT) per 1000 patient days during P1 to 8.91 DOT per 1000 patient days in P2 (p< 0.001). All hospital units showed a significant decrease in carbapenem use, with intensive care step-down unit noting 85.7% reduction (p < 0.00001); floors (medicine, pediatric, surgery) with 61.6% reduction (p< 0.00001); and intensive care units with 52% reduction (p< 0.00001) during P2 compared to P1. Defined daily doses per 1000 patient days decreased from 314.9 in P1 to 93.4 in P2 (p< 0.00001). During P2, 58.3% (132/228) of carbapenem orders were found to be appropriate compared to 37.5% (190/506) in P1 (p< 0.00001). Sensitivity profile for Pseudomonas aeruginosa improved from 86% carbapenem sensitivity during P1 to 89% in P2. No Carbapenem Resistant Enterobacteriaceae isolates were identified. Cost savings of $643 per 1000 patient days were recognized in P2 as a result of reduced carbapenem use. Conclusion There was a significant decline in total carbapenem utilization, an increase in proportion of appropriate use and considerable cost savings as a result of ASP interventions.

The Impact

Background.We evaluated the impact of education and an antifungal stewardship program for candidiasis on prescribing practices, antifungal consumption, Candida species infections, and estimated costs at a Thai tertiary care hospital.Methods.A hospital-wide, quasi-experimental study was conducted for 1.5 years before the intervention and 1.5 years after the implementation of an antifungal stewardship program. Inpatient antifungal prescriptions were prospectively observed, and patients' demographic, clinical, and administrative-cost data were collected. Interventions included education, introduction of an antifungal hepatic and/or renal dose adjustment tool, antifungal prescription forms, and prescription-control strategies.Results.After the intervention, there was a 59% reduction in antifungal prescriptions (from 194 to 80 prescriptions per 1,000 hospitalizations; P < .001). Inappropriate antifungal use decreased (from 71% to 24%; P < .001), a sustained reduction in antifungal use was observed (r = 0.83; P < .001), and fluconazole use decreased (from 242 to 117 defined daily doses per 1,000 patient-days; P < .001). Reductions in the incidence of infection with Candida glabrata (r = 0.69; P < .001) and Candida krusei (r = 0.71; P < .001) were observed, whereas the incidence of infection with Candida albicans (r = —0.81; P < .001) increased. Total cost savings were US$31,615 during the 18-month postintervention period.Conclusions.Implementation of an antifungal stewardship program was associated with appropriate antifungal drug use, improved resource utilization, and cost savings.

Abstract Background A regional antibiotic stewardship program (ASP) within a large integrated healthcare system covering two, non-academic, tertiary care medical centers and an additional six community hospitals implemented multiple interventions to optimize antimicrobial therapy and reduce unnecessary hospital costs, such as transition to extended-infusion (EI) piperacillin/tazobactam (TZP), formulary restriction of antimicrobials, and antimicrobial stewardship clinical review. The purpose of this study was to evaluate the cost savings associated with these regional ASP initiatives. Methods This was a multicenter, retrospective, observational review of regional stewardship interventions across eight inpatient medical centers in Oregon. Data was collected from January 2019 to December of 2020. Cost savings associated with reduced TZP administrations was based on the duration of therapy for each encounter in adults who received TZP for &gt;24 hours in 2020. The regional antimicrobial restriction policy was implemented in February 2020. Cost savings attributed to antimicrobial formulary restrictions and reduction in overall days of therapy/1000 patient days (DOT) were based on EPIC costs. Results The reduction in number of administrations with implementation of EI TZP resulted in &226,420 saved in 2020. &182,837 was saved due to decreased usage of restricted antimicrobial agents. An additional &433,341 was saved for overall antimicrobial costs due to 19,775 days reduction in overall DOT/1000 patient days. Conclusion A community-based regional ASP has resulted in substantial financial impact and identified areas for future cost savings within the region.

Global Threat

Background: Carbapenem-resistant Enterobacteriaceae (CRE) has emerged as a global threat with mortality risk ranging from 48%-71% worldwide. The emergence of MBL resistance is threatening as carbapenem is one of the last line antibiotics. A total 24 variants of NDM resistance raises a concern to the clinicians and epidemiologists worldwide. Objective: The study aims at identifying MBL resistance (NDM, IMP, VIM, GIM, SPM, and SIM) and its coexistence in clinical isolates in a single tertiary care center. Methodology: Forty five clinical isolates characterized phenotypically for Carbapenem resistance obtained from PSG Institute of Medical Science and Research (PSG IMSR), Coimbatore, between February to March 2018 were taken for analysis. Result: Out of the 45 Clinical isolates, 38 isolates (84%) were detected as MBL carriers. VIM, NDM, GIM, and SPM were the predominant resistance genes, with detection rates of 48.8%, 28.8%, 24.4%, and 22.2% respectively. Fifteen isolates were observed to harbor more than one MBL gene in coexistence. Two isolates - U42 and R714 (K. pneumoniae) were found to harbor all 5 MBL variants in combination. Conclusion: 33% of clinical isolates harboring multiple MBL variants is a concern in clinical settings. The presence of SPM and GIM gene amongst isolates in this geographical location within India is an indicator demanding continuous monitoring of these resistance determinants.

Background: Antimicrobial decision making in the ICU is challenging. Injudicious use of antimicrobials contributes to the development of resistant pathogens and drug-related adverse events. However, inadequate antimicrobial therapy is associated with mortality in critically ill patients. Antimicrobial stewardship programs are increasingly being implemented to improve prescribing. Methods: This prospective study was conducted over 11 months, during which the pharmacist used a standardized survey form to collect data on antibiotic use. Evaluation of antimicrobial use and stewardship practices in a 12-bed polytrauma ICU and a 20-bed neurosurgery ICU of the 248-bed AIIMS Trauma Center in Delhi, India. Antimicrobial consumption was measured using WHO-recommended defined daily dose (DDD) of given antimicrobials and days of therapy (DOT). Results: Antibiotics were ranked by frequency of use over the 11-month period based on empirical therapy and culture-based therapy. The 11-month DDD and DOT averages when empiric antibiotics were used were 532 of 1,000 patient days and 484 per 1,000 patient days, respectively (Figure 1). When cultures were available, DDD was 486 per 1,000 patient days and DOT was 442 per 1,000 patient days (Figure). Conclusions: The quantity and frequency of antibiotics used in the ICUs allowed the AMSP to identify areas to optimize antibiotic use such as educational initiatives, early specimen collection, and audit and feedback opportunities.Funding: NoDisclosures: None

Clinical Culture

Abstract Background Clinical culture results are sometimes used to estimate the burden of multidrug-resistant organisms (MDROs) in hospitals. The association between positive clinical culture results and prevalence of MDROs in the gut is incompletely understood. Methods Rectal swab or stool samples were collected daily from adult medical intensive care unit (MICU) patients and cultured for target MDROs using selective media between January 2017 and January 2018 at Rush University Medical Center, a 676-bed tertiary-care center in Chicago. Resistance mechanisms were confirmed by phenotypic methods and/or polymerase chain reaction. Clinical culture results during MICU stay were extracted from the hospital information system. Target MDROs included vancomycin-resistant Enterococci (VRE), carbapenem-resistant Enterobacteriaceae (CRE), extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL), carbapenem-resistant Pseudomonas aeruginosa (CRPA) and carbapenem-resistant Acinetobacter baumannii (CRAB). Patients with either a study or clinical culture positive for a target MDRO were analyzed. Results We collected 5,086 study samples from 1,661 unique admissions (1,419 patients) and included here data from 413 unique admissions (397 patients) with completed microbiologic analysis. Median (IQR) patient age was 65 (51–75) years and length of MICU stay was 3 (3–4) days. A total of 156 (37.8%) patients had a target MDRO detected from a study sample at any point; 57 (36.5%) patients had &gt;1 MDRO detected. Overall prevalence of these MDROs was found to be 22.5% VRE, 6.5% CRE, 19.8% ESBL, 4.4% CRPA, and 0.7% CRAB. New MDRO acquisition was observed in 58 (14.6%) patients (figure). Once a target MDRO was detected in a study sample, 82.2% of subsequent study samples were positive for that MDRO. Only 13 (5.8%) patients had a positive clinical culture for any target MDRO during their MICU stay (table). Conclusion Clinical cultures capture only the tip of the resistance iceberg and alone are insufficient to guide MDRO-targeted prevention strategies. Universal infection prevention measures are an alternative that may be preferred in settings where overall prevalence of MDROs is moderate or high and patients may be colonized with &gt;1 MDRO.

Abstract PURPOSE: The purpose of the study is to estimate the rate of infection with carbapenem-resistant Enterobacteriaceae (CRE) in the main governmental tertiary care hospital in Bahrain. MATERIALS AND METHODS: All clinical samples with positive growth of CRE over 6-year period (January 2012–December 2017) were collected from the microbiology laboratory data. RESULTS: The CRE incidence was high in the first half of study period (2012–2014) and then decreased between 2015 and 2017, after implementation of intensified CRE control measure bundle. About 49.4% of CRE-positive samples were isolated from the elderly age group (above 65 years old), most of them were admitted in the intensive care unit (ICU). The most common isolated organisms were Klebsiella pneumoniae (87.0%), followed by Escherichia coli (7.9%). Isolates from deep tracheal aspirate and midstream urine specimens were the most common source of CRE isolates (27.3%) and (26.3%), respectively. Bacteremia was documented in 21.2% of cases. CRE isolates in the study showed high rates of resistance to aminoglycosides (72.2% resistant to amikacin and 67.3% to gentamicin). Alternatively, most isolates retained their susceptibility to colistin and tigecycline with sensitivity of 83.9% and 85.7%, respectively. Combined resistance to both colistin and tigecycline was observed in 0.06% of total isolates. CONCLUSION: Elderly population and ICU admission were important risk factors for CRE acquisition. Most of CRE isolates were sensitive to both colistin and tigecycline, which make them the best combination for empiric frontline therapy for suspected serious CRE infection in our facility. Implementing CRE-bundled infection control measures significantly reduced the incidence of CRE infection in our hospital.

Abstract Background According to the literature, 25% to 50% of antimicrobials prescribed in hospitals are unnecessary or inappropriate, directly impacting antimicrobial resistance. Thus, the present study aimed to evaluate the use of antimicrobials in a university hospital in Northeast Brazil, using days of therapy (DOT) and length of therapy (LOT) indicators in accordance with the latest national and international recommendations for monitoring the use of antimicrobials. Methods This is an observational, prospective analytical study conducted in a teaching hospital, with 94 active beds, distributed between the intensive care unit (ICU), the surgical clinic (SUR), the medical clinic (MED), the pneumology/infectology department (PNE/INF) and pediatrics (PED). The duration of the study was from the beginning of January to the end of December 2018. Results During the study period, a total of 11,634 patient-days were followed up and 50.4% of the patients were found to have received some antimicrobial, with a significant reduction in use of 1% per month throughout the year. Patients were receiving antimicrobial therapy for 376 days in every 1000 days of hospitalization (LOT = 376/1000pd). Overall, the 1st-generation cephalosporins and fluoroquinolones were the most used in respect of the number of prescriptions and the duration of therapy. The calculated global DOT/LOT ratio showed that each patient received an average of 1.5 antimicrobials during the hospital stay. The incidence of antimicrobial resistance, globally, for both methicillin-resistant Staphylococcus aureus (methicillin R), Carbapenem-resistant Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii (Carbapenem R), was 1 per 1000 patient-days. Conclusions The results obtained from the analyses revealed that half of the patients admitted to the hospital who took part in the study were exposed to the use of antimicrobials at some point during their stay. Although moderate, it is noteworthy that there was a decline in the use of antimicrobials throughout the year. The indicators used in this study were found to be very effective for gathering data on the use of antimicrobials, and assessing the results of the initiatives taken as part of the Stewardship program.
