Antimicrobial Stewardship Initiatives: A Programmatic Approach to Optimizing Antimicrobial Use

We surveyed faculty and residents to assess attitudes, perceptions, and knowledge about antimicrobial use and resistance. Most respondents were concerned about resistance when prescribing antibiotics and agreed that antibiotics are overused, that inappropriate use is professionally unethical, and that others, but not themselves, overprescribe antibiotics. Antimicrobial stewardship programs should capitalize on these perceptions.

Background: The CDC NHSN launched the Antimicrobial Use Option in 2011. The Antimicrobial Use Option allows users to implement risk-adjusted antimicrobial use benchmarking within- and between- facilities using the standardized antimicrobial administration ratio (SAAR) and to evaluate use over time. The SAAR can be used for public health surveillance and to guide an organization’s stewardship or quality improvement efforts. Methods: Antimicrobial Use Option enrollment grew through partner engagement, targeted education, and development of data benchmarking. We analyze enrollment over time and discuss key drivers of participation. Results: Initial 2011 Antimicrobial Use Option enrollment efforts awarded grant Funding: to 4 health departments. These health departments partnered with hospitals, which encouraged vendors to build infrastructure for electronic antimicrobial use reporting. CDC supported vendors through outreach and education. In 2012, with CDC support, Veterans’ Affairs (VA) Informatics, Decision-Enhancement, and Analytic Sciences Center and partners began implementation of Antimicrobial Use Option reporting and validation of submitted data. These early efforts led to enrollment of 64 facilities by 2014 (Fig. 1). As awareness of the antimicrobial use option grew, we focused on facility engagement and development of benchmark metrics. A second round of grant Funding: in 2015 supported submission to the Antimicrobial Use Option from additional facilities by Funding: a vendor, a healthcare system, and an antimicrobial stewardship network. In 2015, CMS recognized the Antimicrobial Use Option as a choice for public health registry reporting under Meaningful Use Stage 3, resulting in an increase in participating hospitals. Antimicrobial Use Option enrollment increased in 2015 (n = 120), coinciding with national prioritization of antimicrobial stewardship. In 2016, the SAAR, was released in NHSN. We leveraged the SAAR to encourage participation from additional facilities and began quarterly calls to encourage continued participation from existing users. In 2016, the Department of Defense began submitting data to the Antimicrobial Use Option, resulting in 207 facilities enrolled in 2016, which grew to 616 in 2017. As of November 2019, 12 vendors self-report submission capabilities and 1,470 facilities, of ~6,800 active NHSN participants, are enrolled in the Antimicrobial Use Option. Two states have passed requirements regulating Antimicrobial Use Option reporting with Tennessee’s requirement going into effect in 2021. Conclusions: The Antimicrobial Use Option offers evidence that collaboration with partners, and leveraging of benchmarking metrics available to a national surveillance system can lead to increased voluntary participation in surveillance of high-priority public health data. Moving forward, we will continue expanding analytic capabilities and partner engagement.Funding: NoneDisclosures: None

Over Time

Abstract Background About 30–50% of inpatient antimicrobial therapy is sub-optimal. Health care facilities have utilized various antimicrobial stewardship (AS) strategies to optimize appropriate antimicrobial use, improve health outcomes, and promote patient safety. However, little evidence exists to assess relationships between AS strategies and antimicrobial use. This study examined the impact of changes in AS strategies on antimicrobial use over time. Methods This study used data from the Veterans Affairs (VA) Healthcare Analysis & Informatics Group (HAIG) AS survey, administered at 130 VA facilities in 2012 and 2015, and antimicrobial utilization from VA Corporate Data Warehouse. Four AS strategies were examined: having an AS team, feedback mechanism on antimicrobial use, infectious diseases (ID) attending physicians, and clinical pharmacist on wards. Change in AS strategies were computed by taking the difference in the presence of a given strategy in a facility between 2012–2015. The outcome was the difference between antimicrobial use per 1000 patient days in 2012–2013 and 2015–2016. Employing multiple regression analysis, changes in antimicrobial use was estimated as a function of changes in AS strategies, controlling for ID human resources in and organizational complexity. Results Of the 4 strategies, only change in availability of AS teams had an impact on antimicrobial use. Compared to facilities with no AS teams at both time points, antibiotic use decreased by 63.9 uses per 1000 patient days in facilities that did not have a AS team in 2012 but implemented one in 2015 (p=0.0183). Facilities that had an AS team at both time points decreased use by 62.2 per 1000 patient days (p=0.0324). Conclusion The findings showed that AS teams reduced inpatient antibiotic use over time. While changes in having feedback on antimicrobial use and clinical pharmacist on wards showed reduced antimicrobial use between 2012–2015, the differences were not statistically significant. These strategies may already be a part of a comprehensive AS program and employed by AS teams. In further development of stewardship programs within healthcare organizations, the association between AS teams and antibiotic use should inform program design and implementation.

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.

Antimicrobial Administration

Background: Hospitals in the United States have been encouraged to report antimicrobial use (AU) to the CDC NHSN since 2011. Through the NHSN Antimicrobial Use Option module, health systems may compare standardized antimicrobial administration ratios (SAARs) across specific facilities, patient care locations, time periods, and antimicrobial categories. To date, participation in the NHSN Antimicrobial Use Option remains voluntary and the value of reporting antimicrobial use and receiving monthly SAARs to multihospital healthcare systems has not been clearly demonstrated. In this cohort study. we examined potential applications of SAAR within a healthcare system comprising multiple local hospitals. Methods: Three hospitals within Prisma Health-Midlands (hospitals A, B, and C) became participants in the NHSN Antimicrobial Use Option in July 2017. SAAR reports were presented initially in October 2017 and regularly (every 3–4 months) thereafter during interprofessional antimicrobial stewardship system-wide meetings until end of study in June 2019. Through interfacility comparisons and by analyzing SAAR categories in specific patient-care locations, primary healthcare providers and pharmacists were advised to incorporate results into focused antimicrobial stewardship initiatives within their facility. Specific alerts were designed to promote early de-escalation of antipseudomonal β-lactams and vancomycin. The Student t test was used to compare mean SAAR in the preintervention period (July through October 2017) to the postintervention period (November 2017 through June 2019) for all antimicrobials and specific categories and locations within each hospital. Results: During the preintervention period, mean SAAR for all antimicrobials in hospitals A, B, and C were 0.69, 1.09, and 0.60, respectively. Notably, mean SAARs at hospitals A, B, and C in intensive care units (ICU) during the preintervention period were 0.67, 1.36, and 0.83 for broad-spectrum agents used for hospital-onset infections and 0.59, 1.27, and 0.68, respectively, for agents used for resistant gram-positive infections. After antimicrobial stewardship interventions, mean SAARs for all antimicrobials in hospital B decreased from 1.09 to 0.83 in the postintervention period (P < .001). Mean SAARs decreased from 1.36 to 0.81 for broad-spectrum agents used for hospital-onset infections and from 1.27 to 0.72 for agents used for resistant gram-positive infections in ICU at hospital B (P = .03 and P = .01, respectively). No significant changes were noted in hospitals A and C. Conclusions: Reporting AU to the CDC NHSN and the assessment of SAARs across hospitals in a healthcare system had motivational effects on antimicrobial stewardship practices. Enhancement and customization of antimicrobial stewardship interventions was associated with significant and sustained reductions in SAARs for all antimicrobials and specific antimicrobial categories at those locations.Funding: NoneDisclosures: None

The Impact

Background: The rise of antimicrobial resistance has made it critical for clinicians to understand antimicrobial stewardship principles. We sought to determine whether the opportunity to participate in an American Board of Pediatrics Maintenance of Certification Part 4 (MOC4) quality improvement (QI) project would engage pediatricians and improve their knowledge about antimicrobial stewardship. Methods: In August 2019, a new clinical algorithm for acute appendicitis, spearheaded by the antimicrobial stewardship program (ASP), was implemented at UCSF Benioff Children’s Hospital Oakland to standardize care and optimize antimicrobial use. Medical staff were invited to participate in a QI project evaluating the impact of this algorithm. Data were collected for the 2 quarters preceding implementation (baseline), for the quarter of implementation (transition period), and for the quarter after implementation. Participants were offered MOC4 credit for reviewing these 3 cycles of data and associated materials highlighting information about antimicrobial stewardship. An initial survey was given to participants to assess their baseline knowledge via 4 questions about antimicrobial use in surgical patients (Table 1). At the conclusion of the QI project, another survey was conducted to reassess participant knowledge and to evaluate overall satisfaction with the project. Results: In total, 150 clinicians completed the initial survey. Of these, 44% were general pediatricians and 56% were pediatric subspecialists. Based on years out of training, their levels of experience varied: >20 years in 24%, 11–20 years in 32.7%, 0–10 years in 34.7%, and currently in training in 8.7%. Of the 150 initial participants, 133 (89%) completed the QI project and the second survey. Between surveys, there was significant improvement in knowledge about the appropriate timing and duration of surgical antibiotic prophylaxis (Table 1). Moreover, 88% of participants responded that the QI project was extremely effective in helping them learn about antimicrobial stewardship principles and about ASP interventions. Conclusions: Participation in this MOC4 QI project resulted in significant improvement in knowledge about antimicrobial use in surgical patients, and the activity was perceived as a highly effective way to learn about antimicrobial stewardship. QI projects that leverage MOC4 credit can be a powerful tool for engaging pediatricians and disseminating education about antimicrobial stewardship.Funding: NoDisclosures: None

Group Name: VHA Center for Antimicrobial Stewardship and Prevention of Antimicrobial Resistance (CASPAR) Background: Antimicrobial stewardship programs (ASPs) are advised to measure antimicrobial consumption as a metric for audit and feedback. However, most ASPs lack the tools necessary for appropriate risk adjustment and standardized data collection, which are critical for peer-program benchmarking. We created a system that automatically extracts antimicrobial use data and patient-level factors for risk-adjustment and a dashboard to present risk-adjusted benchmarking metrics for ASP within the Veterans’ Health Administration (VHA). Methods: We built a system to extract patient-level data for antimicrobial use, procedures, demographics, and comorbidities for acute inpatient and long-term care units at all VHA hospitals utilizing the VHA’s Corporate Data Warehouse (CDW). We built baseline negative binomial regression models to perform risk-adjustments based on patient- and unit-level factors using records dated between October 2016 and September 2018. These models were then leveraged both retrospectively and prospectively to calculate observed-to-expected ratios of antimicrobial use for each hospital and for specific units within each hospital. Data transformation and applications of risk-adjustment models were automatically performed within the CDW database server, followed by monthly scheduled data transfer from the CDW to the Microsoft Power BI server for interactive data visualization. Frontline antimicrobial stewards at 10 VHA hospitals participated in the project as pilot users. Results: Separate baseline risk-adjustment models to predict days of therapy (DOT) for all antibacterial agents were created for acute-care and long-term care units based on 15,941,972 patient days and 3,011,788 DOT between October 2016 and September 2018 at 134 VHA hospitals. Risk adjustment models include month, unit types (eg, intensive care unit [ICU] vs non-ICU for acute care), specialty, age, gender, comorbidities (50 and 30 factors for acute care and long-term care, respectively), and preceding procedures (45 and 24 procedures for acute care and long-term care, respectively). We created additional models for each antimicrobial category based on National Healthcare Safety Network definitions. For each hospital, risk-adjusted benchmarking metrics and a monthly ranking within the VHA system were visualized and presented to end users through the dashboard (an example screenshot in Figure 1). Conclusions: Developing an automated surveillance system for antimicrobial consumption and risk-adjustment benchmarking using an electronic medical record data warehouse is feasible and can potentially provide valuable tools for ASPs, especially at hospitals with no or limited local informatics expertise. Future efforts will evaluate the effectiveness of dashboards in these settings.Funding: NoDisclosures: None

Abstract Background The study aimed to assess the development of antimicrobial stewardship (AMS) program in China’s tertiary hospitals to identify the potential challenges for AMS program and provide references and benchmarks for strategic policymaking. Methods A nationwide cross-sectional study was conducted online by sending questionnaires to tertiary hospitals under China Antimicrobial Resistance Surveillance System (CARSS) between November 1, 2018 and December 10, 2018. The questionnaire included 5 sections regarding structure, technical support, antimicrobial use management, antimicrobial use surveillance and education. Descriptive statistics were used for data analysis. Results Of 1044 tertiary hospitals under CARSS, 13.4% (140) hospitals participated in the study. Among them, 99.3% (139/140) set up AMS program. Hospital president (82.1%, 115/140) and medical service department (59.3%, 83/140) were responsible for AMS outcomes in most hospitals. Structured antimicrobial formulary restriction management was adopted by 99.3% (139/140) hospitals. Infection disease department, infection control department and microbiological laboratories were established in 87.1% (122/140), 99.3% (139/140), and 100% (140/140) hospitals, respectively. Up to 85.6% (124/140) hospitals applied clinical pathways and 33.6% (47/140) hospitals implemented hospital-specific guidelines for infectious diseases. Outpatient prescription audit, inpatient prescription audit and prophylactic antimicrobial prescription audit of aseptic operation were performed in 99.3% (139/140), 98.6% (138/140) and 95.7% (134/140) hospitals, respectively. Up to 97.1% (136/140) hospitals participated in antimicrobial use surveillance network and 99.3% (139/140) hospitals established the specialized management of carbapenem and tigecycline. Staff education and AMS-related popular science education were provided with different ways and frequency in 100% (140/140) and 88.6% (124/140) hospitals, respectively. Conclusions AMS in China’s tertiary hospitals were primarily headed by hospital presidents and involved collaboration among various disciplines and administrative departments. More efforts should be put into further promoting and strengthening the development of hospital-specific guidelines and the establishment of progress and outcome evaluation system.

The Impact

BACKGROUND Antimicrobial stewardship (AMS) programs aim to optimize antimicrobial use by utilizing a suite of coordinated strategies. With the increased use of health information technology in hospitals, AMS processes that were traditionally paper-based are becoming computerized and streamlined. A number of reviews on digital interventions supporting AMS have been performed, so we performed a review of reviews to consolidate findings OBJECTIVE To provide a systematic overview and synthesis of evidence on the effectiveness of digital interventions to improve antimicrobial prescribing and monitoring in hospitals. METHODS Databases: Medline, Embase, Scopus, CINAHL and the Cochrane Database of Systematic Reviews were searched from 2010 onwards. Papers were eligible if they included studies that examined the effectiveness of digital health interventions related to antimicrobial prescribing and monitoring, in an inpatient hospital setting. Papers were excluded if they did not include a clearly defined search strategy, if they were limited to a pediatric setting, or they were not in English. RESULTS Seven systematic reviews were included for data extraction. Five reviews were of moderate quality and two of low quality. A large number of digital interventions were evaluated, with a strong focus on clinical decision support. There was a large variability in outcome measures used. Six reviews reported that digital interventions reduced antimicrobial use and improved antimicrobial appropriateness. The impact of digital interventions on clinical outcomes was inconsistent. CONCLUSIONS The results of this review indicate digital interventions, regardless of type, reduce antimicrobial use and improve antimicrobial appropriateness in hospitals. We recommend hospitals consider implementing one or more digital interventions to facilitate AMS programs.
