Antimicrobial Stewardship Interventions in a Hospital Setting

Abstract Background Antimicrobial stewardship initiatives and efforts have historically had a greater emphasis in the inpatient hospital setting. There is a need for outpatient stewardship, and additionally, accreditation standards are starting to require antimicrobial stewardship efforts in the ambulatory care setting. Fluoroquinolones are a target for antimicrobial stewardship based on their broad-spectrum activity, pharmacokinetics/pharmacodynamics, safety profile, downstream resistance, and risk of super infections. The objective of this study was to compare outpatient fluoroquinolone prescribing rates before and after pharmacist led initiative. Methods This was a prospective, quality improvement initiative between October 1, 2019 to June 1, 2020 at a community-based physician network across Indiana. The pharmacist initiative incorporated a live, educational presentation with intervention 1 and an informational letter to healthcare providers across the outpatient physician network with intervention 2. Data was collected from a computer-generated, prescription report. The primary outcome was fluoroquinolone prescribing rates at Central Indiana (CI) sites before and after pharmacist led interventions. Rate of fluoroquinolone prescribing was defined as total number of fluoroquinolone prescriptions per month. The secondary outcome included percentage of fluoroquinolone use at CI sites. Percentage of fluoroquinolone use was defined as monthly number of fluoroquinolones prescriptions compared to monthly number of all oral antibiotic prescriptions. Results There was a 29.8% decrease (382 vs 268 prescriptions) in outpatient fluoroquinolone prescriptions at CI sites after intervention 1 compared to same month of previous year. There was a 43.7% decrease (428 vs 241 prescriptions) in outpatient fluoroquinolone prescriptions at CI sites after intervention 2. There was an overall 2.4% decrease (4.9% vs 2.5%) in percentage of fluoroquinolone use compared to all oral antibiotics at CI sites after intervention 2 compared to same month of previous year. Conclusion These findings suggest the pharmacist led outpatient antimicrobial stewardship initiative successfully decreased fluoroquinolone prescribing rates across the network.

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.

ObjectivesThis study responds to calls for greater focus on nursing roles, and the need for nursing integration within the antimicrobial optimisation agenda. The objective of this study was to explore Australian hospital nurses’ views on antimicrobial resistance and antimicrobial stewardship (AMS) in a hospital setting, in order to better understand the opportunities for and challenges to integration of nursing staff in antimicrobial optimisation within hospital settings.DesignQualitative one-on-one, semistructured interviews. Interview transcripts were digitally audio-recorded and transcribed verbatim. Data were subject to thematic analysis supported by the framework approach and informed by sociological methods and theory.SettingFour hospitals (three public and one private), across metropolitan, regional and remote areas, in two Australian states.Participants86 nurses (77 females, 9 males), from a range of hospital departments, at a range of career stages.ResultsFindings were organised into three thematic domains: (1) the current peripheral role of nurses in AMS; (2) the importance of AMS as a collaborative effort, and current tensions around interprofessional roles and (3) how nurses can bolster antimicrobial optimisation within AMS and beyond.ConclusionNursing staff are central to infection management within the hospital and are thus ideally located to enhance antibiotic optimisation and contribute to AMS governance. However, without increased interprofessional cooperation, education and integration in the AMS agenda, as well as addressing organisational/resource constraints in the hospital, the nursing role in stewardship will remain limited.

The Impact

Abstract Background Antimicrobial stewardship (AS) implementation is challenging in resource-limited settings such as smaller community hospitals that may lack dedicated personnel resources or have limited access to infectious diseases experts with dedicated time for AS. Few studies have evaluated the impact of interdisciplinary rounds as a strategy to optimize antimicrobial use (AU) in the community hospital setting. Methods We evaluated the impact of interdisciplinary rounds in a 280-bed acute care nonteaching, community hospital with an established ASP. The primary outcome was facility-wide antibiotic utilization pre- and post-implementation. Rounds included key healthcare personnel (hospitalists, clinical pharmacists, case managers, nurses) reviewing all patients on inpatient wards Monday through Friday, with a discussion of diagnosis, antibiotic selection, dosing, duration, and anticipated discharge plans. AU was compared for a 7-month post-intervention period (June 1, 2018–December 31, 2018) vs. similar months in 2017 based on days of therapy (DOT)/1,000 patient-days and length of therapy (LOT) per antimicrobial use admission. In addition, trends in AU for the post-intervention period were compared with the previous 17 months (January 1, 2017–May 31, 2018) using segmented binomial regression. Results Interdisciplinary rounds incorporating AS principles was associated with a decrease in overall AU in this facility, with a significant decrease of 16.33% (P < 0.0001) in DOT/1,000 pd in the first month and was stable (decrease of 1.1% per month, P = 0.15) thereafter (Figure 1). There was no significant change in LOT/admission after the first month of the intervention, but the trend demonstrated a 2% per month decrease (P < 0.03) thereafter (Figure 2). Comparing 2018 intervention months with similar months of 2017, the use of antibacterial agents decreased on average by 191.3 (95% CI −128.2 to −254.4) DOT/1,000 patient-days (Figure 3) and 0.546 (95% CI: −0.28 to −0.81) days per admission (Figure 4). Conclusion In this community hospital with an existing antimicrobial stewardship program, implementation of interdisciplinary rounds was associated with a substantial decrease in antimicrobial use. This was sustained for at least a 7-month period. Disclosures All authors: No reported disclosures.

Introduction Proper measures to combat antimicrobial resistance development and spread in Sub Saharan Africa are very crucial bearing in mind the projected burden of antimicrobial resistance which is expected to be increase by 2050. Training of medical doctor and pharmacy students in antimicrobial stewardship is vital to combat antimicrobial resistance. This study was designed to evaluate the knowledge, attitude, and perception of final year medical and pharmacy students on antimicrobial use and antimicrobial resistance at three universities in Uganda, Kenya, and Tanzania. Methodology A cross-sectional survey was carried out among final year undergraduate medical and pharmacy students at three universities in East Africa. A Self-administered questionnaire was developed which included dichotomous questions and questions using a 4-point Likert scale. The questions were based on knowledge and attitude about antibiotics, and preparedness to use antibiotics in clinical scenarios. Data were analyzed using STATA version 16 following the objective of the study. Results Three hundred and twenty-eight final year students participated in the survey from MUK 75, MKU 75 and CUHAS 178. Slightly majority of participants were male 192(58.5%) and their median age was 25 [23 – 27] years. In general, 36.6% (120/328) of students had good overall total knowledge. More students at MUK had good knowledge compared to MKU, and CUHAS (72% vs, 40% vs. 20.2%; p<0.001). The mean scores for overall good total knowledge, general knowledge about antibiotics, knowledge about antibiotic resistance, and knowledge about antibiotic use in clinical scenarios were 58% (CI: 57%– 60%), 95% (CI: 94%– 97%), 54% (CI: 52% - 56%), and 46% (CI:44% - 48%) respectively. More pharmacy students compared to medical students had a good attitude and perception on antibiotic use (79.6% vs. 68.4%; p = 0.026). The students at CUHAS perceived being more prepared to use antibiotic in district hospitals compared to MKU and MUK (75.3% vs. 62.7% vs. 65.3%; p = 0.079). While two hundred and seventy (82.3%) students perceived knowing when to start antimicrobial therapy, 112 (34.2%) did not know how to select the appropriate antibiotic (p<0.0001), 97 (29.6%) did not know the antibiotic dose to give (p<0.0001), and 111 (33.8%) did not know when to switch form an intravenous antibiotic to oral regimen (p<0.0001). Conclusion Final year students have low scores in knowledge about antimicrobial resistance and antibiotic use in clinical scenarios. This has exposed gaps in practical training of students, while they may feel confident, are not fully prepared to prescribe antibiotics in a hospital setting. A multidisciplinary and practical approach involving medical schools across the East African region should be undertaken to train final year undergraduate students in antimicrobial resistance and antimicrobial stewardship programs. Antimicrobial resistance and antimicrobial stewardship courses should be introduced into the curriculum of final year medicine and pharmacy programs.

The Impact

Abstract Background Community hospitals have fewer resources for antimicrobial stewardship programs (ASP) compared to larger tertiary hospitals. At our 312-bed community hospital, Long Island Jewish Forest Hills/Northwell, a combination of modified preauthorization, prospective audit feedback, and ASP education was implemented starting in August 2019 (Monday through Friday 9 am to 5 pm). Methods This retrospective study evaluated the impact of ASP interventions on the rate of targeted antimicrobial use over a 7 month pre- vs 7 month post- intervention period (Aug 2018 to Feb 2019 vs Aug 2019 to Feb 2020). Targeted antimicrobials included piperacillin-tazobactam, vancomycin, daptomycin, and carbapenems. The primary outcome was the monthly mean for overall targeted antimicrobial use measured by the rate of antimicrobial days per 1000 days present. Secondary outcomes were the individual rates of antimicrobial days per 1000 days present for each of the targeted antimicrobials, and the hospital’s overall standardized antimicrobial administration ratio (SAAR). Data were analyzed as a segmented regression of interrupted time series. Results Pre-intervention, there was an increasing trend (positive slope, p< 0.05) in the monthly mean, hospital SAAR, vancomycin and piperacillin-tazobactam use. Post-intervention, there was a significant change in slope for these same metrics, indicating a decrease in the mean use. Immediate impact of ASP interventions, measured by the difference in antibiotic use between the end of each intervention period, was visually evident in all cases except carbapenems (Fig. 1 through 4). The immediate impact on the overall monthly mean represented a significant reduction in the rate of antimicrobial days per 1000 days present, -12.72 (CI -21.02 to -4.42, P < 0.0066). The pre- vs post- ASP gap for all measures was negative and consistent with fewer days of antibiotic use immediately following intervention. Conclusion A targeted, multifaceted ASP intervention utilizing modified preauthorization, prospective audit feedback, and education significantly reduced antibiotic use in a community hospital.

Abstract Background Most studies on hospital antimicrobial stewardship (AMS) status and practices are conducted in the west, and there is a lack of such data from Asian countries. The objective of this survey was to determine existing AMS practices and gaps, and challenges in implementing AMS programs in secondary and tertiary acute-care hospitals in 10 Asian countries. Methods A 70-item questionnaire was disseminated to hospitals fulfilling inclusion criteria and responses were collected from 10 April 2020 to 9 April 2021. The survey, specific to the Asian hospital setting, enquired about hospital leadership support for AMS; AMS team membership and training; AMS interventions; AMS monitoring and reporting; hospital infrastructure; and education. These were subdivided into core and supplementary components, adapted from the Transatlantic Taskforce on Antimicrobial Resistance set of core and supplementary indicators for hospital AMS programs, and the US Centers for Disease Control and Prevention checklist for core elements of hospital AMS programs. Results A total of 349 hospitals from Cambodia, India, Indonesia, Japan, Malaysia, Pakistan, Philippines, Taiwan, Thailand and Vietnam responded. Overall, only 47 hospitals fulfilled all 12 core components, and there were inter-country differences in terms of performance. The hospitals generally did well in terms of the AMS team (ie, comprising at least a physician leader responsible for AMS activities, a pharmacist, and infection control and microbiology personnel), and access to a timely and reliable microbiology service, with mean positive response rates (PRR) of ≥ 80% for these indicators (Figure 1). In the core components of AMS program interventions, and AMS monitoring and reporting, the lower mean PRR ( > 60%) revealed that Asia has wider gaps in these areas versus gold standards. Although many hospitals had formal hospital leadership statements to support AMS (mean PPR 85.6%), this was not always matched by allocated financial support for AMS activities (mean PPR 57.1%). Figure 1 Conclusion For all core components of an AMS program, most Asian hospitals participating in this survey fell short of international gold standards. Inter-country differences in gaps highlight that country-specific solutions are needed to improve current standards in AMS.
