The Impact of an Antimicrobial Stewardship Program on Days of Therapy in the Pediatric Center: An Interrupted Time-Series Analysis of a 19-Year Study. J Korean Med Sci 2024; 39:e172. [PMID: 38832477 PMCID: PMC11147790 DOI: 10.3346/jkms.2024.39.e172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 04/29/2024] [Indexed: 06/05/2024] Open
Abstract
BACKGROUND We aimed to analyze the effects of an antimicrobial stewardship program (ASP) on the proportion of antimicrobial-resistant pathogens in bacteremia, antimicrobial use, and mortality in pediatric patients. METHODS A retrospective single-center study was performed on pediatric inpatients under 19 years old who received systemic antimicrobial treatment from 2001 to 2019. A pediatric infectious disease attending physician started ASP in January 2008. The study period was divided into the pre-intervention (2001-2008) and the post-intervention (2009-2019) periods. The amount of antimicrobial use was defined as days of therapy per 1,000 patient-days, and the differences were compared using delta slope (= changes in slopes) between the two study periods by an interrupted time-series analysis. The proportion of resistant pathogens and the 30-day overall mortality rate were analyzed by the χ². RESULTS The proportion of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae bacteremia increased from 17% (39 of 235) in the pre-intervention period to 35% (189 of 533) in the post-intervention period (P < 0.001). The total amount of antimicrobial use significantly decreased after the introduction of ASP (delta slope value = -16.5; 95% confidence interval [CI], -30.6 to -2.3; P = 0.049). The 30-day overall mortality rate in patients with bacteremia did not increase, being 10% (55 of 564) in the pre-intervention and 10% (94 of 941) in the post-intervention period (P = 0.881). CONCLUSION The introduction of ASP for pediatric patients reduced the delta slope of the total antimicrobial use without increasing the mortality rate despite an increased incidence of ESBL-producing gram-negative bacteremia.

Abstract
The identification of antimicrobial use patterns is essential for determining key targets for antimicrobial stewardship interventions and evaluating the effectiveness thereof. Accurately identifying antimicrobial use patterns requires quantitative evaluation, which focuses on measuring the quantity and frequency of antimicrobial use, and qualitative evaluation, which assesses the appropriateness, effectiveness, and potential side effects of antimicrobial prescriptions. This paper summarizes the quantitative and qualitative methods used to evaluate antimicrobials, drawing insights from overseas and domestic cases.

Abstract
BACKGROUND AND PURPOSE Pneumonia and bronchopneumonia are the most common infectious diseases in children. This study aimed to analyze changes in causative pathogens and antibiotic use for bronchopneumonia or pneumonia after the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in children. METHODS This retrospective study was conducted from 2009 to 2019. Hospitalized children aged 6 months-3 years with a discharge diagnosis of bronchopneumonia or pneumonia were included to analyze changes in the potential mismatch between the diagnosed pathogen and antibiotic use. RESULTS The cohort comprised 1100 patients, including 648 (59%) and 452 (41%) with a discharge diagnosis of bronchopneumonia and pneumonia, respectively. The trend of viral pneumonia increased every year (rs = 0.101, p < 0.05) Antibiotics were administered in 97% patients, with an increasing annual trend in macrolide use (rs = 0.031, p = 0.009). Regarding antibiotic utilization, no significant variations were observed in the days of therapy (DOT) (rs = 0.076, p = 0.208) or length of therapy (LOT) (rs = -0.027, p = 0.534) per patient-year throughout the study duration. Interestingly, the LOT for combined therapy with macrolides and first-line beta-lactams was high (rs = 0.333, p = 0.028). In viral pneumonia treatment, neither the DOT nor LOT exhibited significant variations (rs = -0.006, p = 0.787 and rs = -0.156, p = 0.398). CONCLUSION After the introduction of PCV13 in Taiwan, no decrease in antibiotic use has been observed among children aged 6 months-3 years with a discharge diagnosis of bronchopneumonia and pneumonia.

Abstract
BACKGROUND Infectious disease (ID) specialists are skilled facilitators of medical consultation who promote better outcomes in patient survival, antibiotic stewardship as well as healthcare safety in pandemic response. This study aimed to assess the working status of ID specialists and identify problems faced by ID professionals in Korea. METHODS This was a nationwide cross-sectional study in Korea. An online-based survey was conducted over 11 days (from December 17-27, 2020), targeting all active adult (n = 281) and pediatric (n = 71) ID specialists in Korea (N = 352). Questions regarding the practice areas of the specialists were divided into five categories: 1) clinical practices of outpatient care, inpatient care, and consultations; 2) infection control; 3) antibiotic stewardship; 4) research; and 5) education and training. We investigated the weekly time-use patterns for these areas of practice. RESULTS Of the 352 ID specialists, 195 (55.4%; 51.2% [144/281] adult and 71.8% [51/71] pediatric ID specialists) responded in the survey. Moreover, 144 (73.8%) of the total respondents were involved in all practice categories investigated. The most common practice area was outpatient service (93.8%), followed by consultation (91.3%) and inpatient service (87.7%). Specialists worked a median of 61 (interquartile range: 54-71) hours weekly: patient care, 29 (14-37) hours; research 11 (5-19) hours; infection control 4 (2-10) hours; antibiotic stewardship, 3 (1-5) hours; and education/training, 2 (2-6) hours. CONCLUSION ID specialists in Korea simultaneously undertake multiple tasks and work long hours, highlighting the need for training and employing more ID specialists.

Abstract
Currently, antimicrobial resistance (AMR) is a major threat to global public health. The antimicrobial stewardship program (ASP) has been proposed as an important approach to overcome this crisis. ASP supports the optimal use of antimicrobials, including appropriate dosing decisions, administration duration, and administration routes. In Korea, efforts are being made to overcome AMR using ASPs as a national policy. The current study aimed to develop core elements of ASP that could be introduced in domestic medical facilities. A Delphi survey was conducted twice to select the core elements through expert consensus. The core elements for implementing the ASP included (1) leadership commitment, (2) operating system, (3) action, (4) tracking, (5) reporting, and (6) education. To ensure these core elements are present at medical facilities, multiple departments must collaborate as teams for ASP operations. Establishing a reimbursement system and a workforce for ASPs are prerequisites for implementing ASPs. To ensure that ASP core elements are actively implemented in medical facilities, it is necessary to provide financial support for ASPs in medical facilities, nurture the healthcare workforce in performing ASPs, apply the core elements to healthcare accreditation, and provide incentives to medical facilities by quality evaluation criteria.

Exploring Antimicrobial Stewardship Influential Interventions on Improving Antibiotic Utilization in Outpatient and Inpatient Settings: A Systematic Review and Meta-Analysis. Antibiotics (Basel) 2022; 11:antibiotics11101306. [PMID: 36289964 PMCID: PMC9598859 DOI: 10.3390/antibiotics11101306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/18/2022] [Accepted: 09/21/2022] [Indexed: 11/30/2022] Open
Abstract
Antimicrobial stewardship interventions are targeted efforts by healthcare organizations to optimize antimicrobial use in clinical practice. The study aimed to explore effective interventions in improving antimicrobial use in hospitals. Literature was systemically searched for interventional studies through PubMed, CINAHL, and Scopus databases that were published in the period between January 2010 to April 2022. A random-effects model was used to pool and evaluate data from eligible studies that reported antimicrobial stewardship (AMS) interventions in outpatient and inpatient settings. Pooled estimates presented as proportions and standardized mean differences. Forty-eight articles were included in this review: 32 in inpatient and 16 in outpatient settings. Seventeen interventions have been identified, and eight outcomes have been targeted. AMS interventions improved clinical, microbiological, and cost outcomes in most studies. When comparing non-intervention with intervention groups using meta-analysis, there was an insignificant reduction in length of stay (MD: -0.99; 95% CI: -2.38, 0.39) and a significant reduction in antibiotics' days of therapy (MD: -2.73; 95% CI: -3.92, -1.54). There were noticeable reductions in readmissions, mortality rates, and antibiotic prescriptions post antimicrobial stewardship multi-disciplinary team (AMS-MDT) interventions. Studies that involved a pharmacist as part of the AMS-MDT showed more significant improvement in measured outcomes than the studies that did not involve a pharmacist.

Abstract
Emerging pathogens in the meantime of paucity of new antibiotics discovery, put antimicrobial stewardship in the center of attention, to preserve the existing antimicrobial effect. Implementation of antimicrobial stewardship programs, however, needs approval from healthcare system managers. The approval process can be enhanced, when the beneficial effects of stewardship programs are supported by both clinical and financial evidence. Focusing on the financial outcome evaluation, the practitioners who run the stewardship programs, may choose certain methods and metrics, depending on the clinical setting scale and type, available human resources, and budget. The wise selection of the methods and metrics warrants a comprehensive insight of the existing methods and metrics, deployed by typically published works that set good examples to follow. This review is an attempt to provide such an insight along with typical relevant examples for each metric and method.

Abstract
Background: The antimicrobial stewardship program (ASP) is a coordinated intervention designed to improve and measure the appropriate antibiotics use by selecting an optimal antibiotic drug regimen, including dosing, therapy duration, and administration route. The implementation of ASPs decreases the consumption, cost, and adverse effects of antibiotic use. Additionally, it improves the clinical outcomes, and decreases Clostridium difficile infection and antimicrobial resistance.Current Concepts: To overcome the antimicrobial resistance and implement ASPs worldwide, various efforts are underway, such as enacting ASP guidelines, developing core elements for ASP implementation, introducing ASPs to the healthcare accreditation system, and providing healthcare facilities with adequate incentives to implement ASPs. In Korea, ASP guidelines were published in September 2021, and core elements for ASP implementation are being developed at the time of writing. However, there is a shortage of personnel required for the ASP team, including healthcare workforce and infectious disease specialists for leading the team Moreover, financial support for ASP implementation in the National Health Insurance Service is not provided yet. The awareness of hospital leadership and clinicians prescribing antibiotics for ASP implementation is still low. The reimbursement system establishment and workforce for ASPs are prerequisite for the implementation of ASPs.Discussion and Conclusion: At the national level, it is necessary to provide financial support for ASPs in healthcare facilities, nurture the healthcare workforce in performing ASPs, and advocate ASP education and publicity.

Abstract
Objective: The objective of the study was to assess the impact of multifaceted clinical pharmacist-led antimicrobial stewardship (AMS) program on the rational use of antibiotics for patients who receive vascular and interventional radiology therapies. Methods: A quasi-experimental retrospective intervention design with a comparison group was applied to the practice of antibiotic use in the department of vascular and interventional radiology in a Chinese tertiary hospital. We used difference-in-differences (DID) analysis to compare outcomes before and after the AMS intervention between the intervention group and control group, to determine whether intervention would lead to changes in irrationality of antibiotic prescribing, antibiotic utilization, cost of antibiotics, and length of hospital stay. Results: The DID results showed that the intervention group was associated with a reduction in the average consumption of antibiotics (p = 0.017) and cost of antibiotics (p = 0.006) and cost per defined daily dose (DDD) (p = 0.000). There were no significant differences in the mean change of total costs and length of stay between the two groups (p > 0.05). The average inappropriate score of perioperative antimicrobial prophylaxis in the intervention group declined by 0.23, while it decreased by 0.02 in the control group [0.21 (95% CI, -0.271 to -0.143); p = 0.000]. The average inappropriate score of non-surgical antimicrobial prophylaxis in the intervention group declined by 0.14, while it increased by 0.02 in the control group [0.16 (95% CI, -0.288 to -0.035); p = 0.010]. The average inappropriate score of the therapeutic use of antibiotics in the intervention group declined by 0.07, while it decreased by 0.01 in the control group [0.06 (95% CI, -0.115 to -0.022); p = 0.003]. Conclusions: This study provides evidence that implementation of AMS interventions was associated with a marked reduction of antibiotic use, cost of antibiotics, and irrationality of antibiotic prescribing in China.

Abstract
Aim To evaluate the changes in antimicrobial consumption and multidrug-resistant microorganism trends after introducing an empiric antimicrobial therapy manual to support antimicrobial stewardship. Methods A 4-year prospective interventional study assessed the effect of introducing an empiric antimicrobial therapy manual in medical and surgical wards during two periods: pre-intervention period (January 2015–May 2017) and post-intervention period (June 2017–December 2019). Outcomes included microorganism trends of bloodstream infections (BSI) for Klebsiella pneumoniae carbapenemase-producing bacteria (KPC), extended spectrum beta-lactamase ESBL-E. coli, meticillin-resistant Staphylococcus aureus (MRSA) and Candida albicans. Also, Clostridioides difficile infection (CDI) episodes were included. Rates were normalised per 1000 patient-days (PD). Antimicrobial consumption was assessed as defined daily dose (DDD)/1000 PD in interrupted time series analysis. Results In medical wards, we observed a significant decrease in the consumption of piperacillin-tazobactam and a decrease in the trends of tigecycline and vancomycin consumption. In surgical wards, there was a significant decrease in consumption of fluoroquinolones and piperacillin-tazobactam. This decrease was maintained in trend for all the antimicrobials but was significant for tigecycline only. In medical wards, there was a significant reduction of MRSA and C. albicans. In surgical wards, we observed a decrease in MRSA, ESBL-E. coli, C. albicans and CDI. KPC cases decreased by 22.5% in medical wards and 74.3% in surgical wards. Conclusion The results suggest that a persuasive educational approach to antimicrobial stewardship, with the introduction of an empiric antimicrobial manual and continuous education, resulted in reductions in both antimicrobial use and healthcare-associated BSI caused by multidrug-resistant organisms. More studies with longer follow up are needed to investigate the effect of antimicrobial stewardship on clinical outcomes.

Abstract
These guidelines were developed as a part of the 2021 Academic R&D Service Project of the Korea Disease Control and Prevention Agency in response to requests from healthcare professionals in clinical practice for guidance on developing antimicrobial stewardship programs (ASPs). These guidelines were developed by means of a systematic literature review and a summary of recent literature, in which evidence-based intervention methods were used to address key questions about the appropriate use of antimicrobial agents and ASP expansion. These guidelines also provide evidence of the effectiveness of ASPs and describe intervention methods applicable in Korea.

Hwang S, Kwon KT. Core Elements for Successful Implementation of Antimicrobial Stewardship Programs. Infect Chemother 2021; 53:421-435. [PMID: 34623776 PMCID: PMC8511365 DOI: 10.3947/ic.2021.0093] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 09/11/2021] [Indexed: 12/23/2022] Open
Abstract
Antimicrobial resistance has emerged as a serious global public health threat. One of the countermeasures to increased antibiotic-resistant bacterial infections is the use of an integrative intervention strategy for the selection and administration of appropriate antibiotics and for the monitoring of antibiotic use, collectively known as "Antimicrobial Stewardship Programs" (ASPs). However, since the medical environment and policies vary by country and medical facilities, ASPs also need to be applied to each facility and condition accordingly. The United States Centers for Disease Control and Prevention announced the core elements for hospital ASPs, which outlines the specific structural and procedural components required to implement ASPs in 2014. As multidrug-resistant bacterial infections and use of broad-spectrum antibiotics in Korea are on the rise, ASPs must be urgently applied to medical facilities for appropriate management of antibiotic use. However, there is an ongoing limitation to the immediate adoption and application of ASPs in Korean medical facilities due to the lack of medical workforce and related financial resources. To address this issue, efforts of medical professionals and government are required, and core elements that match the characteristics and circumstances of Korean medical facilities must be urgently developed.

Abstract
OBJECTIVES This study aimed to analyse the effect of discontinuation of antimicrobial stewardship programme (ASP) activity on the usage pattern of antibiotics. METHODS An interrupted time-series analysis assessing the trends in antibiotic use was conducted between September 2015 and August 2019 in an 859-bed university-affiliated hospital in Korea, where all ASP activities were discontinued in March 2018. The major activity of the ASP was a restrictive antibiotic programme. RESULTS The use of restrictive antibiotics increased immediately after the discontinuation of the ASP by 41.06 days of therapy (DOT)/1000 patient-days in the general ward (95% confidence interval (CI) 21.04-61.08) and by 391.04 DOT/1000 patient-days in the intensive care unit (ICU) (95%CI 207.56-574.51). In addition, there were positive changes in the slope for the use of restrictive antibiotics in the general ward (7.06 DOT/1000 patient-days per month, 95%CI 4.63-9.50) and ICU (35.95 DOT/1000 patient-days per month, 95%CI 18.70-53.19). The use of broad-spectrum antibiotics in the general ward significantly decreased (-87.54 DOT/1000 patient-days, 95%CI -149.29 to -25.79). For non-broad-spectrum antibiotics, there were positive changes in the slope in the general ward (16.54 DOT/1000 patient-days per month, 95%CI 12.99-20.09) and ICU (12.85 DOT/1000 patient-days per month, 95%CI 2.32-23.38). CONCLUSIONS After discontinuation of the ASP, antibiotic usage patterns rapidly returned to the patterns prior to the implementation of the programme.

Abstract
OBJECTIVE To investigate the relationship between the systemic inflammatory response syndrome (SIRS), early antibiotic use, and bacteremia in solid-tumor patients. DESIGN, SETTING, AND PARTICIPANTS We conducted a retrospective observational study of adults with solid tumors admitted to a tertiary-care hospital through the emergency department over a 2-year period. Patients with neutropenic fever, organ transplant, trauma, or cardiopulmonary arrest were excluded. METHODS Rates of SIRS, bacteremia, and early antibiotics (initiation within 8 hours of presentation) were compared using the χ2 and Student t tests. Binomial regression and receiver operator curves were analyzed to assess predictors of bacteremia and early antibiotics. RESULTS Early antibiotics were administered in 507 (37%) of 1,344 SIRS-positive cases and 492 (22%) of 2,236 SIRS-negative cases (P < .0001). Of SIRS-positive cases, 70% had blood cultures drawn within 48 hours and 19% were positive; among SIRS negative cases, 35% had cultures and 13% were positive (19% vs 13%; P = .003). Bacteremic cases were more often SIRS positive than nonbacteremic cases (60% vs 50%; P =.003), but they received early antibiotics at similar rates (50% vs 49%, P = .72). Three SIRS components predicted early antibiotics: temperature (OR, 1.7; 95% CI, 1.31-2.29; P = .0001), tachycardia (OR, 1.4; 95% CI, 1.10-1.69; P < .0001), and white blood-cell count (OR, 1.8; 95% CI, 1.56-2.14; P < .0001). Only temperature (OR, 1.6; 95% CI, 1.09-2.41; P = .01) and tachycardia (OR, 1.5; 95% CI, 1.09-2.06; P = .01) predicted bacteremia. SIRS criteria as a composite were poorly predictive of bacteremia (AUC, 0.57). CONCLUSIONS SIRS criteria are frequently used to determine the need for early antibiotics, but they are poor predictors of bacteremia in solid-tumor patients. More reliable models are needed to guide judicious use of antibiotics in this population.

Impact of antifungal stewardship interventions on the susceptibility of colonized Candida species in pediatric patients with malignancy. Sci Rep 2021; 11:14099. [PMID: 34238976 PMCID: PMC8266849 DOI: 10.1038/s41598-021-93421-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 06/18/2021] [Indexed: 12/28/2022] Open
Abstract
There is a worldwide concern regarding the antimicrobial resistance and the inappropriate use of antifungal agents, which had led to an ever-increasing antifungal resistance. This study aimed to identify the antifungal susceptibility of colonized Candida species isolated from pediatric patients with cancer and evaluate the clinical impact of antifungal stewardship (AFS) interventions on the antifungal susceptibility of colonized Candida species. Candida species colonization was evaluated among hospitalized children with cancer in a tertiary teaching hospital, Shiraz 2017–2018. Samples were collected from the mouth, nose, urine, and stool of the patients admitted to our center and cultured on sabouraud dextrose agar. The isolated yeasts identified by polymerase chain reaction–restriction fragment length polymorphisms (PCR–RFLP). DNA Extracted and PCR amplification was performed using the ITS1 and ITS4 primer pairs and Msp I enzyme. The broth microdilution method was used to determine the minimum inhibitory concentrations (MICs) for amphotericin B, caspofungin, and azoles. The prevalence of Candida albicans in the present study was significantly higher than other Candida species. Candida albicans species were completely susceptible to the azoles. The susceptibility rate of C. albicans to amphotericin B and caspofungin was 93.1% and 97.1%, respectively. The fluconazole MIC values of Candida albicans decreased significantly during the post-AFS period (P < 0.001; mean difference: 72.3; 95% CI of the difference: 47.36–98.62). We found that 52.5% (53/117) of the isolated C. albicans were azole-resistant before AFS implementation, while only 1.5% (2/102) of the isolates were resistant after implementation of the AFS program (P < 0.001). C. albicans fluconazole and caspofungin resistant rate also decreased significantly (P < 0.001) after implementation of the AFS program [26 (32.9%) versus 0 (0.0%) and 11 (10.9%) versus 1 (0.9%), respectively]. Besides, fluconazole use (p < 0.05) and fluconazole expenditure reduced significantly (about one thousand US$ per year) after the AFS program. Our results confirm the positive effect of optimized antifungal usage and bedside intervention on the susceptibility of Candida species after the implementation of the AFS program. C. albicans and C. glabrata exhibited a significant increase in susceptibility after the execution of the AFS program.

Impact of antibiotic usage on extended-spectrum β-lactamase producing Escherichia coli prevalence. Sci Rep 2021; 11:13024.

Abstract
An increase in antibiotic usage is considered to contribute to the emergence of antimicrobial resistance.
Although experts are counting on the antimicrobial stewardship programs to reduce antibiotic usage, their effect remains uncertain. In this study, we aimed to evaluate the impact of antibiotic usage and forecast the prevalence of hospital-acquired extended spectrum β-lactamase (ESBL)—producing Escherichia coli (E. coli) using time-series analysis. Antimicrobial culture information of E. coli was obtained using a text processing technique that helped extract free-text electronic health records from standardized data. The antimicrobial use density (AUD) of antibiotics of interest was used to estimate the quarterly antibiotic usage. Transfer function model was applied to forecast relationship between antibiotic usage and ESBL-producing E. coli. Of the 1938 hospital-acquired isolates, 831 isolates (42.9%) were ESBL-producing E. coli. Both the proportion of ESBL-producing E. coli and AUD increased over time. The transfer model predicted that ciprofloxacin AUD is related to the proportion of ESBL-producing E. coli two quarters later. In conclusion, excessive use of antibiotics was shown to affect the prevalence of resistant organisms in the future. Therefore, the control of antibiotics with antimicrobial stewardship programs should be considered to restrict antimicrobial resistance.

Status of antimicrobial stewardship programmes in Korean hospitals including small to medium-sized hospitals and the awareness and demands of physicians: a nationwide survey in 2020. J Glob Antimicrob Resist 2021; 26:180-187. [PMID: 34153526 DOI: 10.1016/j.jgar.2021.06.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 05/26/2021] [Accepted: 06/03/2021] [Indexed: 12/26/2022] Open
Abstract
OBJECTIVES This study aimed to identify the status of antimicrobial stewardship programmes (ASPs) in small to medium-sized Korean hospitals as well as the awareness and demands about ASPs of physicians. METHODS A questionnaire was designed based on a questionnaire from a previous nationwide survey in 2018 targeting large hospitals in Korea and modified to reflect the results of in-depth interviews with non-infectious diseases (IDs) physicians at secondary care hospitals. The survey targeted all hospitals with ≥150 beds in South Korea and was performed in May-June 2020. Only one ASP-associated physician per hospital participated in the survey. RESULTS The survey response rate was 31.9% (217/680). ID specialists comprised the majority of medical personnel participating in ASPs in tertiary care hospitals. Conversely, in secondary and primary care hospitals there was no predominant medical personnel for ASPs and the median full-time equivalent was 0 for all types of medical personnel. Tertiary care hospitals, more than secondary and primary care hospitals, tended to perform ASP activities more actively. 'Workforce for ASPs', 'Establishment of healthcare fees for ASPs' and 'Development of tools for ASPs' were the most important required support for ASP improvement. CONCLUSION The level of ASP establishment was more limited in primary care hospitals than in secondary and tertiary care hospitals in Korea. To improve ASPs in Korean hospitals, a supporting workforce and the establishment of a healthcare fee for ASPs appear to be necessary.

Abstract
BACKGROUND Antimicrobial stewardship (AMS) programmes optimize antimicrobial use and address antimicrobial resistance. Pharmacists are often key agents of these programmes. The effectiveness of hospital-based AMS interventions when they are led by pharmacists, however, has not previously been reported. AIM To evaluate the effectiveness of pharmacist-led AMS interventions in improving antimicrobial use for hospital inpatients. METHODS Standard systematic review methods were used. The search strategies and databases used in a previous Cochrane review were applied. Studies that reported pharmacist-led AMS interventions were included. Narrative synthesis was used to report the findings. PRISMA guidelines were followed. FINDINGS From 6971 records retrieved and screened, 52 full-text articles were included. Most studies were undertaken in teaching hospitals (N = 45) and many were conducted in North America (N = 27). Most interventions targeted junior or ward physicians and lasted between one and six months. All studies evaluated educational interventions often in combination with other interventions and reported improvements 'in compliance with target AMS practice'. Greater compliance was achieved with multiple interventions. Pharmacist-led interventions reduced the duration of antimicrobial therapy without increasing mortality. No consistency of evidence was achieved in relation to interventions and reduced duration of hospital stay, nor infections due to antimicrobial resistance or occurrence of Clostridium difficile. CONCLUSION This is the first systematic review to evaluate the effectiveness of pharmacist-led AMS interventions in hospital inpatients. Education-based interventions were effective in increasing guideline compliance and reducing duration of antimicrobial therapy. Future hospital-based AMS programmes should consider the involvement of pharmacists to deliver and promote AMS interventions and programmes.

Abstract
The development and spread of antimicrobial resistance are major concerns for human and animal health. The effects of the overuse of antimicrobials in domestic animals on the dissemination of resistant microbes to humans and the environment are of concern worldwide. Rhodococcus equi is an ideal model to illustrate the spread of antimicrobial resistance at the animal-human-environment interface because it is a natural soil saprophyte that is an intracellular zoonotic pathogen that produces severe bronchopneumonia in many animal species and humans. Globally, R. equi is most often recognized as causing severe pneumonia in foals that results in animal suffering and increased production costs for the many horse-breeding farms where the disease occurs. Because highly effective preventive measures for R. equi are lacking, thoracic ultrasonographic screening and antimicrobial chemotherapy of subclinically affected foals have been used for controlling this disease during the last 20 years. The resultant increase in antimicrobial use attributable to this "screen-and-treat" approach at farms where the disease is endemic has likely driven the emergence of multidrug-resistant (MDR) R. equi in foals and their environment. This review summarizes the factors that contributed to the development and spread of MDR R. equi, the molecular epidemiology of the emergence of MDR R. equi, the repercussions of MDR R. equi for veterinary and human medicine, and measures that might mitigate antimicrobial resistance at horse-breeding farms, such as alternative treatments to traditional antibiotics. Knowledge of the emergence and spread of MDR R. equi is of broad importance for understanding how antimicrobial use in domestic animals can impact the health of animals, their environment, and human beings.

Abstract
Background This study aimed to investigate psychological distress among infectious disease (ID) physicians during the coronavirus disease 2019 (COVID-19) outbreak in the Republic of Korea. Methods Using an online-based survey link sent via text message and email, we conducted a survey from April 21 to 25, 2020, targeting all ID physicians currently working in ID (n = 265). The questionnaire was based on the Maslach Burnout Inventory-Human Services Survey and the Depression, Anxiety, and Stress Scales, and information was collected on factors protecting against psychological distress and difficulties in relation to COVID-19. Results Of 265 ID physicians, 115 (43.3%) responded, showing burnout (97, 90.4%), depression (20, 17.4%), anxiety (23, 20.0%), and stress (5, 4.3%). There were no differences in terms of distress between ID physicians who were directly involved in the care of patients with COVID-19 or not. Greater than 50% of physicians valued their work and felt recognized by others, whereas < 10% indicated that sufficient human and financial support and private time had been provided during the outbreak. The most challenging issues concerned a lack of attending physicians caring for COVID-19 patients or infection control practitioners, a shortage of personal protective equipment or airborne infection isolation rooms, pressure for research, and lack of guidelines for COVID-19 management. Conclusions During the COVID-19 outbreak in the Republic of Korea, most respondents reported psychological distress. Preparing strategies to secure human resources are crucial to prepare effectively for future epidemics and pandemics.

Abstract
OBJECTIVES We calculated the human resources required for an antimicrobial stewardship program (ASP) in Korean hospitals. DESIGN Multicenter retrospective study. SETTING Eight Korean hospitals ranging in size from 295 to 1,337 beds. METHODS The time required for performing ASP activities for all hospitalized patients under antibiotic therapy was estimated and converted into hours per week. The actual time spent on patient reviews of each ASP activity was measured with a small number of cases, then the total time was estimated by applying the determined times to a larger number of cases. Full-time equivalents (FTEs) were measured according to labor laws in Korea (52 hours per week). RESULTS In total, 225 cases were reviewed to measure time spent on patient reviews. The median time spent per patient review for ASP activities ranged from 10 to 16 minutes. The total time spent on the review for all hospitalized patients was estimated using the observed number of ASP activities for 1,534 patients who underwent antibiotic therapy on surveillance days. The most commonly observed ASP activity was 'review of surgical prophylactic antibiotics' (32.7%), followed by 'appropriate antibiotics recommendations for patients with suspected infection without a proven site of infection but without causative pathogens' (28.6%). The personnel requirement was calculated as 1.20 FTEs (interquartile range [IQR], 1.02-1.38) per 100 beds and 2.28 FTEs (IQR, 1.93-2.62) per 100 patients who underwent antibiotic therapy, respectively. CONCLUSION The estimated time required for human resources performing extensive ASP activities on all hospitalized patients undergoing antibiotic therapy in Korean hospitals was ~1.20 FTEs (IQR, 1.02-1.38) per 100 beds.

Abstract
This study reports the effect of implementing an antibiotic stewardship program (ASP) based on the "handshake" strategy for 2 years on multiple endpoints compared with that in a preceding period when an antimicrobial restriction policy was only applied in the absence of a complete program in a tertiary-care Lebanese hospital. The studied endpoints were broad-spectrum antibiotic consumption, antibiotic expenditure, nosocomial bacteremia incidence rate, and patient outcome.An interrupted time series analysis was undertaken to assess the changes in the trend (ΔT) and level (ΔL) of the aforementioned endpoints among adult inpatients before (October 2013 to September 2015) and after the introduction of the ASP (October 2016 to September 2018).After the implementation of the "handshake" ASP, marked changes were observed in the consumption of broad-spectrum antibiotics. The mean use density levels for imipenem and meropenem decreased by 13.72% (P = 0.017), coupled with a decreasing rate of prescription (ΔT = -24.83 defined daily dose [DDD]/1,000 patient days [PD]/month; P = 0.02). Tigecycline use significantly decreased in level by 69.19% (P < 0.0001) and in trend (ΔT = -25.63 DDD/1,000 PD/month; P < 0.0001). A reduction in the use of colistin was also documented but did not reach statistical significance (ΔL = -8.71%, P = 0.56; ΔT = -5.51 DDD/1,000 PD/month = -5.5; P = 0.67). Antibiotic costs decreased by 24.6% after ASP implementation (P < 0.0001), and there was a distinct change from an increasing rate to a decreasing rate of expenditure (ΔT = -12.19 US dollars/PD/month; P = 0.002). The incidence rate of nosocomial bacteremia caused by carbapenem-resistant gram-negative bacteria (CRGNB) decreased by 34.84% (P = 0.13) coupled with a decreasing trend (ΔT = -0.23 cases/1,000 PD/month, P = 0.08). Specifically, a noticeable reduction in the incidence rate of bacteremia due to carbapenem-resistant Acinetobacter baumannii was documented (ΔL = -54.34%, P = 0.01; ΔT = -0.24 cases/1000 PD/month, P = 0.01). Regarding patient outcome, all-cause mortality rates did not increase in level or in rate (ΔL = -3.55%, P = 0.59; ΔT = -0.29 deaths/1000 PD/month, P = 0.6). The length of stay and 7-day readmission rate remained stable between the two periods.In conclusion, the "handshake" ASP succeeded in controlling the prescription rates of antibiotics and in decreasing the nosocomial bacteremia rates caused by CRGNB without compromising patient outcome in our facility. It also had an economic effect in reducing antibiotic costs compared with the previous restriction policy on antimicrobial dispensing.

Abstract
BACKGROUND Implementing a successful antimicrobial stewardship program (ASP) is difficult for non-academic community (NAC) hospitals due to insufficient infrastructure. AIM We evaluated the impact of an infectious disease specialist (IDS) on implementing an ASP in a resource-limited setting in Korea. METHODS A retrospective study was performed at a NAC hospital between June 2015 and August 2018. An IDS has led an ASP at the hospital since June 2017. We used an interrupted time series analysis to evaluate longitudinal effects of the IDS-led ASP on the amount of antibiotic use and incidence of multidrug-resistant organism (MDRO) acquisition. FINDINGS Total antibiotic use changed from 698.82 ± 74.41 to 602.09 ± 69.94 defined daily dose/1000 patient-days (PDs) after intervention. An immediate reduction in the use of carbapenems, glycopeptides, penicillins, and other antibiotics followed the IDS-led ASP. The 3rd/4th generation cephalosporins and carbapenems prescription rates decreased in slope after the intervention. Incidence of MDRO acquisition changed from 1.38, 0.78, and 0.21/1000 PDs to 1.06, 0.15, and 0.32/1000 PDs in methicillin-resistant Staphylococcus aureus, multidrug-resistant Acinetobacter baumannii, and multidrug-resistant Pseudomonas aeruginosa, respectively. The incidence of methicillin-resistant Staphylococcus aureus and multidrug-resistant Acinetobacter baumannii acquisition immediately decreased following intervention. CONCLUSION An IDS can implement a successful ASP by reducing antibiotic consumption and MDRO acquisition at resource-limited NAC hospitals.

Mitchell KF, Safdar N, Abad CL. Evaluating carbapenem restriction practices at a private hospital in Manila, Philippines as a strategy for antimicrobial stewardship. ACTA ACUST UNITED AC 2019; 77:31. [PMID: 31312447 PMCID: PMC6610803 DOI: 10.1186/s13690-019-0358-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 06/13/2019] [Indexed: 11/10/2022]
Abstract
Background Hospital antimicrobial stewardship programs are especially critical in countries such as the Philippines, where antibiotic resistant infections are highly prevalent. At the study institution in Manila, Philippines, a Prior Approval for Restricted Antimicrobials (PARA) is required for non-infectious disease specialists to prescribe certain antimicrobials, including carbapenems. PARA request forms include specification of empiric or definitive therapy based on diagnostic tests. Recommended duration of therapy is typically 3 days for empiric use and 7 days for definitive, with possible extension upon specialist approval. Methods The study took place at an 800-bed tertiary hospital. We performed a retrospective review of patient medical records and laboratory reports dating from January 1 to December 31, 2016. Information related to patient demographics, carbapenem prescription, laboratory diagnosis, and therapy were compiled. Carbapenem prescriptions were classified as 'adherent' or 'non-adherent' according to clinical guidelines related to infection diagnosis, treatment duration, and de-escalation. Results Of the 185 patients on carbapenem therapy, Prescriptions of carbapenems were either definitive (n = 56), empiric (n = 127), or prophylactic (n = 2) as defined by the ordering provider. 69 out of 185 (37%) prescriptions were deemed non-adherent to guidelines, despite receiving approvals for their respective requests. Of these, 72% were non-adherent due to failure to de-escalate the carbapenem and 28% were non-adherent due to an incomplete course of therapy. Conclusion Despite initial PARA approval for carbapenem therapy, 37% of prescriptions were non-guideline-adherent, highlighting the ongoing challenges in implementing this type of stewardship strategy. In order to increase the effectiveness of PARA, additional approaches may be warranted, including the application of strict policies which reinforce follow-up of available culture results, justification of therapy extension, or referral to an infectious disease specialist.

Abstract
Rhodococcus equi causes severe pneumonia in foals and is most often recognized in people as an opportunistic pathogen. Longitudinal studies examining antimicrobial-resistant R. equi from environmental samples are lacking. We hypothesized that antimicrobial-resistant R. equi would be detectable in the ground (pasture soil or stall bedding) and air at breeding farms with previous documentation of foals infected with resistant isolates, and that concentrations of resistant isolates would increase over time during the foaling season. In this prospective cohort study, ground and air samples were collected from stalls and paddocks in January, March, May and July of 2018 at 10 horse-breeding farms with history of foal pneumonia attributed to macrolide- or Rifampicin-resistant R. equi. Environmental samples were cultured in the presence and absence of macrolides and Rifampicin to select for resistant organisms. Data were analyzed with linear mixed-effects and Hurdle models. Concentrations of total R. equi in bedding or air of stalls were significantly (P < 0.05) higher in January than other months. The proportion of resistant R. equi in soil samples from paddocks was significantly (P < 0.05) higher than stall bedding during all months. For each month, air samples from paddocks had a significantly (P < 0.05) higher proportion of resistant isolates than those from stalls. Fifty-five percent of resistant soil isolates and 34% of resistant air isolates were considered virulent by identification of the vapA gene. Concentrations of resistant R. equi isolates did not increase over time during the foaling season. Antimicrobial-resistant R. equi can persist in the environment at farms with a history of pneumonia caused by resistant R. equi infections, and exposure to resistant isolates in paddocks and stalls appears stable during the foaling season. Resistant isolates in the environment not only pose a risk for disease but also can serve as a repository for dissemination of resistance genes.
