Abstract Purpose A novel automatic discontinuation policy implemented within an antimicrobial stewardship program (ASP) is described, and results of an evaluation of the policy’s effects on antibiotic usage are reported. Methods A retrospective, before-and-after study was conducted at an 800-bed, tertiary care, academic teaching hospital to evaluate selected antibiotic usage outcomes in both intensive care unit (ICU) and non-ICU adult patients targeted for ASP interventions before and after implementation of an automatic discontinuation of antibiotics policy (ADAP) authorizing the ASP team to automatically halt antibiotic therapy in cases involving inappropriate duplicate antimicrobial coverage or excess duration of therapy. The primary outcome was total days of antibiotic therapy. Secondary outcomes included excess days of therapy and rates of 30-day readmission, Clostridioides difficile infection, and multidrug-resistant infection. Results There were no statistically significant differences in group demographics or clinical characteristics. The most common indication for antibiotics was hospital-acquired pneumonia, and the most common reason for ASP intervention was excess duration of therapy. The mean total number of antibiotic days per patient was reduced from 7.6 days in the pre-ADAP group to 6.6 days in the post-ADAP group (p < 0.05). The mean number of excess days of antibiotics was similarly reduced, from 2.3 days to 1.5 days, after implementation of the ADAP (p < 0.05). Conclusion Adoption of an ADAP—a more active approach to ASP interventions—was effective in reducing overall antibiotic usage and improving the efficiency of the ASP.

While antimicrobial stewardship programs (ASPs) are well established at most large medical centers, small or rural facilities often do not have the same resources; therefore, different methods must be developed to start or expand ASPs for these hospitals. The purpose of this quality improvement study was to describe the implementation of a pharmacist-led remote ASP and assess the effect on antimicrobial use. Antimicrobial use in days of therapy per 1000 patient days (DOT/1000 PD) was compared between the six months before and after remote ASP implementation. Changes in system-wide, facility-specific, and target antimicrobial use were evaluated. Pharmacist interventions, acceptance rates, and number of times infectious disease (ID) physician assistance was sought were also tracked. System-wide antimicrobial use was 4.6% less in the post-implementation time period than in the pre-implementation time period, with vancomycin, piperacillin/tazobactam, and fluoroquinolones having the greatest reductions in use. Ninety-one percent of interventions made during the post-implementation period were accepted. ID physician review was requested 38 times, and direct ID physician intervention was required six times. Remote ASPs delivered from a central facility to serve a larger system may reduce antimicrobial use, especially against targeted agents, with minimal increase in ID physician workload.

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&lt; 0.001). All hospital units showed a significant decrease in carbapenem use, with intensive care step-down unit noting 85.7% reduction (p &lt; 0.00001); floors (medicine, pediatric, surgery) with 61.6% reduction (p&lt; 0.00001); and intensive care units with 52% reduction (p&lt; 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&lt; 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&lt; 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.

ABSTRACT We evaluated the use of antimicrobials expressed as defined daily doses (DDDs) per 1,000 patient days and days of therapy (DOT) per 100 occupied bed-days in a intensive care unit (ICU) of a general hospital in Barcelona, Spain, before and after implementation of an antimicrobial stewardship (AMS) program (2007 to 2010 versus 2011 to 2015). The quarterly costs of antimicrobials used in the ICU and its weight in the overall hospital costs of antimicrobials were calculated. The effect of the applied AMS program on DDDs and DOT time series data was analyzed by means of intervention time series analysis. A total of 5,002 patients were included (1,971 for the first [before] period and 3,031 for the second [after] period). The percentage of patients treated with one or more antimicrobials decreased from 88.6 to 77.2% ( P < 0.001). DDDs decreased from 246.8 to 192.3 (mean difference, −54.5; P = 0.001) and DOT from 66.7 to 54.6 (mean difference, −12.1; P = 0.066). The mean cost per trimester decreased from €115,543 to €73,477 (mean difference, −42,065.4 euros; P < 0.001), and the percentage of ICU antimicrobials cost with respect to the total cost of hospital antimicrobials decreased from 28.5 to 22.8% (mean difference, −5.59; P = 0.023). Implementation of an AMS program in the ICU was associated with a marked reduction in the use of antimicrobials, with cost savings close to one million euros since its implementation. An AMS program can have a significant impact on optimizing antimicrobial use in critical care practice.

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.

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.

Polymyxins being last resort drugs to treat infections triggered by multidrug-resistant pathogens necessitates the implementation of antimicrobial stewardship program (ASP) initiatives to support its rational prescription across healthcare settings. Our study aims to describe the change in the epidemiology of polymyxins and patient outcomes following the implementation of ASP at our institution. The antimicrobial stewardship program initiated in February 2016 at our 1300 bed tertiary care center involved post-prescriptive audits tracking polymyxin consumption and evaluating prescription appropriateness in terms of the right indication, right frequency, right drug, right duration of therapy and administration of the right loading dose (LD) and maintenance dose (MD). Among the 2442 polymyxin prescriptions tracked over the entire study period ranging from February 2016 to January 2020, the number of prescriptions dropped from 772 prescriptions in the pre-implementation period to an average of 417 per year during the post-implementation period, recording a 45% reduction. The quarterly patient survival rates had a significant positive correlation with the quarterly prescription appropriateness rates (r = 0.4774, p = 0.02), right loading dose (r = 0.5228, p = 0.015) and right duration (r = 0.4361, p = 0.04). Our study on the epidemiology of polymyxin use demonstrated favorable effects on the appropriateness of prescriptions and mortality benefits after successful implementation of antimicrobial stewardship in a real-world setting.

The effectiveness of antimicrobial stewardship programs (ASP) in reducing antimicrobial use (AU) in children has been proved. Many interventions have been described suitable for different institution sizes, priorities, and patients, with surgical wards being one of the areas that may benefit the most. We aimed to describe the results on AU and length of stay (LOS) in a pre-post study during the three years before (2014–2016) and the three years after (2017–2019) implementation of an ASP based on postprescription review with feedback in children and adolescents admitted for appendix-related intraabdominal infections (AR-IAI) in a European Referral Paediatric University Hospital. In the postintervention period, the quality of prescriptions (QP) was also evaluated. Overall, 2021 AR-IAIs admissions were included. Global AU, measured both as days of therapy/100 patient days (DOT/100PD) and length of therapy (LOT), and global LOS remained unchanged in the postintervention period. Phlegmonous appendicitis LOS (p = 0.003) and LOT (p < 0.001) significantly decreased, but not those of other AR-IAI diagnoses. The use of piperacillin–tazobactam decreased by 96% (p = 0.044), with no rebound in the use of other Gram-negative broad-spectrum antimicrobials. A quasisignificant (p = 0.052) increase in QP was observed upon ASP implementation. Readmission and case fatality rates remained stable. ASP interventions were safe, and they reduced LOS and LOT of phlegmonous appendicitis and the use of selected broad-spectrum antimicrobials, while increasing QP in children with AR-IAI.

Objective Previous analyses of neonatal intensive care units (NICU) antimicrobial stewardship programs have identified key contributors to overall antibiotic use, including prolonged empiric therapy >48 hours for early-onset sepsis (EOS). However, most were performed in mixed NICU settings with onsite birthing units, resulting in a high proportion of inborn patient admissions. The study aimed to describe and analyze the most common reasons for antimicrobial use in an outborn tertiary care NICU. Study Design This was a 10-month review of all antimicrobial doses prescribed in a 20-bed level III NICU. The primary outcome was the total days of therapy (DOT) and length of therapy (LOT) for each clinical indication. Secondary outcomes included total DOT for each antimicrobial and appropriateness of antimicrobial courses. Results Of 235 antibiotic courses and 1,899 DOT (519 DOT/1,000 patient days) prescribed in 173 infants during the study period, the most common indications were suspected EOS, followed by prophylaxis. Among the 85 DOT/1,000 patient days (PD; 38 courses) prescribed for prophylaxis, 52.5 DOT/1,000 PD (25 courses; 62%) were for surgical prophylaxis. Of 17 postoperative antibiotic courses, 15 (88.2%) were deemed to be inappropriate mostly due to a duration greater than 24 hours postoperatively (n = 13; median LOT = 3 days). Conclusion Surgical prophylaxis is a common reason for antimicrobial misuse in outborn NICU. NICU-based prospective audit and feedback between neonatologists and antimicrobial stewardship teams alone may not be impactful in this setting. Partnerships with neonatologists and surgeons will be key to achieving the target of less than 24 hours of postoperative antimicrobials. Key Points

Abstract Background Long-term care facilities (LTCF) often struggle with implementation of antimicrobial stewardship programs (ASP) that meet all CDC core elements (CE). The CDC recommends partnership with infectious diseases (ID)/ASP experts to guide ASP implementation. The Nebraska Antimicrobial Stewardship Assessment and Promotion Program (ASAP) is an initiative funded by NE DHHS via a CDC grant to assist healthcare facilities with ASP implementation. Methods ASAP performed on-site baseline evaluation of ASP in 5 LTCF (42–293 beds) in the spring of 2017 using a 64-item questionnaire based on CDC CE. After interviewing ASP members, ASAP provided prioritized facility-specific recommendations for ASP implementation. LTCF were periodically contacted in the next 12 months to provide implementation support and evaluate progress. The number of CE met, recommendations implemented, antibiotic starts (AS) and days of therapy (DOT)/1000 resident-days (RD), and incidence of facility-onset Clostridioides difficile infections (FO-CDI) were compared 6 to 12 months before and after on-site visits. Paired t-test and Wilcoxon signed rank test were used for statistical analyses. Results Multidisciplinary ASP existed in all 5 facilities at baseline with medical directors (n = 2) or directors of nursing (n = 3) designated as team leads. Median CE implemented increased from 3 at baseline to 6 at the end of follow-up (P = 0.06). No LTCF had all 7 CE at baseline. By the end of one year, 2 facilities implemented all 7 CE with the remaining implementing 6 CE. LTCF not meeting all CE were only deficient in reporting ASP metrics to providers and staff. Among the 38 recommendations provided by ASAP, 82% were partially or fully implemented. Mean AS/1000 RD reduced by 19% from 10.1 at baseline to 8.2 post-intervention (P = 0.37) and DOT/1000 RD decreased by 21% from 91.7 to 72.5 (P = 0.20). The average incidence of FO-CDI decreased by 75% from 0.53 to 0.13 cases/10,000 RD (P = 0.25). Conclusion Assessment of LTCF ASP along with feedback for improvement by ID/ASP experts resulted in more programs meeting all 7 CE. Favorable reductions in antimicrobial use and CDI rates were also observed. Moving forward, the availability of these services should be expanded to all LTCFs struggling with ASP implementation.

Background Clinical decision support (CDS) embedded into the electronic health record (EHR), is a potentially powerful tool for institution of antimicrobial stewardship programs (ASPs) in emergency departments (EDs). However, design and implementation of CDS systems should be informed by the existing workflow to ensure its congruence with ED practice, which is characterized by erratic workflow, intermittent computer interactions, and variable timing of antibiotic prescription. Objective This article aims to characterize ED workflow for four provider types, to guide future design and implementation of an ED-based ASP using the EHR. Methods Workflow was systematically examined in a single, tertiary-care academic children's hospital ED. Clinicians with four roles (attending, nurse practitioner, physician assistant, resident) were observed over a 3-month period using a tablet computer-based data collection tool. Structural observations were recorded by investigators, and classified using a predetermined set of activities. Clinicians were queried regarding timing of diagnosis and disposition decision points. Results A total of 23 providers were observed for 90 hours. Sixty-four different activities were captured for a total of 6,060 times. Among these activities, nine were conducted at different frequency or time allocation across four roles. Moreover, we identified differences in sequential patterns across roles. Decision points, whereby clinicians then proceeded with treatment, were identified 127 times. The most common decision points identified were: (1) after/during examining or talking to patient or relative; (2) after talking to a specialist; and (3) after diagnostic test/image was resulted and discussed with patient/family. Conclusion The design and implementation of CDS for ASP should support clinicians in various provider roles, despite having different workflow patterns. The clinicians make their decisions about treatment at different points of overall care delivery practice; likewise, the CDS should also support decisions at different points of care.
