A nationwide mixed-methods study of gaps and barriers to implementation of antimicrobial stewardship programmes in hospitals in Indonesia

There is an urgent need to understand the implementation barriers of antimicrobial stewardship programs (ASP) in low- and middle-income countries. We conducted a mixed-methods study in public and private hospitals across all provinces in Indonesia (March-December 2023). We used a self-assessment questionnaire with a scoring system, and multilevel ordinal regression to assess associations with hospital and district-level characteristics. Focus group discussions (FGD) with hospital stakeholders examined barriers and enablers. We applied a patient safety framework to integrate results. 575 (19%) of 3026 hospitals completed the self-assessment, of whom 516 (89.7%) had a formal ASP (median 4 [IQR1-5] years), and 14 participated in FGD. The median overall ASP development score was 48.4% (35.9-62.5%), classifying 41 (8.0%) hospitals as inadequate (0-25%), 237 (45.9%) as basic (26-50%), 179 (34.7%) as intermediate (51-75%) and 59 (11.4%) as advanced (76-100%). Scores were highest for hospital leadership support (83.4% [66.7-100%]), followed by ASP team and infectious disease training (66.7% [55.6-77.8%]); education (50% [0.0-75.0%]); ASP interventions (43.8% [18.7-68.7%]); hospital infrastructure (42.9% [14.3-71.4%]); and monitoring, reporting and feedback (40.9% [27.3-54.5%]). A higher ASP development score was associated with higher hospital tiered level, longer ASP duration, and higher district-level public health development index and per capita domestic expenditure, but not with hospital ownership or geographic region. FGDs highlighted barriers related to hospital leadership support, staff technical and behavioral skills, cross-disciplinary collaboration, fear of loss of prescriber autonomy, microbiology and IT support, and hospital accreditation. Identified implementation barriers can inform actions for context-specific, sustainable improvement of ASPs.

Microfoundations of Data-Driven Antimicrobial Stewardship Policy (ASP).

This paper introduces a comprehensive framework that elucidates the microfoundations of data-driven antimicrobial stewardship programs (ASPs), specifically focusing on resource-constrained settings. Such settings necessitate the utilization of available resources and engagement among multiple stakeholders. The microfoundations are conceptualized as interlinked components: input, process, output, and outcome. Collectively, these components provide a comprehensive framework for understanding the development and implementation of data-driven ASPs in resource-constrained settings. It underscores the importance of considering both the social and material dimensions when evaluating microbiological, clinical, and social impacts. By harmonizing technology, practices, values, and behaviors, this framework offers valuable insights for the development, implementation, and assessment of ASPs tailored to resource-constrained environments.

Understanding the role of veterinarians in antimicrobial stewardship on Canadian dairy farms: A mixed-methods study.

The aim of this study was to describe the factors that influence dairy cattle veterinarians´ antimicrobial prescribing, their attitudes toward reducing antimicrobial use (AMU) in the dairy industry, awareness of antimicrobial resistance (AMR), and perceived barriers to improving antimicrobial stewardship (AMS) on Canadian dairy farms. We used quantitative and qualitative research methods to consider the complexity of the antimicrobial prescription decision-making process. We designed and distributed an online survey, followed by four online focus groups with practicing veterinarians. We used frequency tables and unconditional associations to analyze quantitative data, and thematic analysis to analyze qualitative data. In total, 107 participants from four Canadian provinces responded to the survey, and 26 veterinarians participated in the focus groups. Results from both studies were triangulated to draw our key findings. We found that 1) Veterinarians must weigh numerous intra-personal and contextual considerations that could be conflicting in their decision-making process for prescribing antimicrobials. 2) Although less experienced veterinarians showed greater awareness of AMR and motivation to improve AMS than more experienced veterinarians, they also reported feeling more pressure to adapt their prescribing practices to farmers' wishes than more experienced veterinarians. 3) Some veterinarians experienced conflict between prescribing antimicrobials to maintain animal health, productivity, and welfare, and AMS, which could result in blaming others for inappropriate antimicrobial use and reducing the opportunity to critically review their own prescribing practices. 4) There were strategies and barriers in common between veterinarians and farmers such as collaborative reviews of disease treatment protocols and improving preventive medicine on dairy farms. 5) The main barriers to reducing AMU on dairy farms reported by veterinarians were concerns about animal welfare and AMU on dairy farms without consultation with the veterinarian. Our results can inform the development of AMS programs in the Canadian dairy industry.

Antimicrobial stewardship programs in seven Latin American countries: facing the challenges

BackgroundStudies have shown that more than 50% of the antibiotics used in hospitals are unnecessary or inappropriate and, that antimicrobial resistance may cost up to 20 billion USD in excess medical costs each year. On the other hand, Antimicrobial Stewardship Programs (ASP) significantly reduce inappropriate antimicrobial use, emergence of antimicrobial resistance, healthcare associated infections, and costs in hospital settings.ObjectiveTo evaluate the development of ASP and antibiotic savings in 7 Latin American hospitals using standardized quantitative indicators in all the participating health care institutions.MethodsAn interventional study was conducted, where pre- and post- evaluations were performed using a standardized score tool adapted from the Joint Commission International accreditation standards and, the Colombian Institute of Technical Standards and Certification. We evaluated ASP from 7 Latin American hospitals between 2019 and 2020. A pre-intervention evaluation was done in each hospital to quantify the degree of development of the ASP (ASP Development score). Based on these results, tailored on-site training was implemented in each hospital, followed by a post-intervention evaluation to quantify improvement of ASP-development indicators. In addition, monetary savings in antimicrobials derived from the ASP intervention were estimated.ResultsIn the pre-intervention evaluation, the average ASP development score for the 7 institutions was 65.8% (40-94.3%). The items with the lowest development score were those related to monitoring and communicating the ASP progress and success. For the post-intervention evaluation, 2 institutions couldn’t participate due to the pressure imposed by the COVID-19 pandemic. For the remaining 5/7 hospitals, the average ASP development score was 82.3% with an increase of 12.0% when compared to the pre-intervention measurement of the same institutions (average pre-intervention score 70.3% (48.2%-94.3%) The items with a significant increase were key performance indicators, AMS education and training of the prescribers. Three of the seven (3/7) hospitals reported antibiotic monetary savings associated to the ASP intervention.ConclusionsThe use of the tool described shown to be useful to evaluate specific areas of ASP-development that were lacking and tailor interventions for the participating hospitals, consequently, it helped improve ASP-development in the institutions that underwent pre- intervention and post-intervention analysis. In addition, the strategies showed monetary savings on antimicrobial costs when measured.

Deep Dive Into Gaps and Barriers to Implementation of Antimicrobial Stewardship Programs in Hospitals in Latin America.

Antimicrobial resistance has worsened in Latin America. There is an urgent need to understand the development of antimicrobial stewardship programs (ASPs) and the barriers to implementing effective ASPs in light of limited national action plans or policies to promote ASPs in the region. We performed a descriptive mixed-methods study of ASPs in 5 Latin American countries in March-July 2022. An electronic questionnaire with an associated scoring system (hospital ASP self-assessment) was used, and ASP development was classified based on the scores (inadequate, 0-25; basic, 26-50; intermediate, 51-75; or advanced, 76-100). Interviews among healthcare workers (HCWs) involved in antimicrobial stewardship (AS) inquired about behavioral and organizational factors that influence AS activities. Interview data were coded into themes. Results from the ASP self-assessment and interviews were integrated to create an explanatory framework. Twenty hospitals completed the self-assessment, and 46 AS stakeholders from these hospitals were interviewed. ASP development was inadequate/basic in 35% of hospitals, intermediate in 50%, and advanced in 15%. For-profit hospitals had higher scores than not-for-profit hospitals. Interview data validated the self-assessment findings and provided further insight into ASP implementation challenges, which included limited formal hospital leadership support, inadequate staffing and tools to perform AS work more efficiently, limited awareness of AS principles by HCWs, and limited training opportunities. We identified several barriers to ASP development in Latin America, suggesting the need to create accurate business cases for ASPs to obtain the necessary funding for their effective implementation and sustainability.

Interventions to Improve Antibiotic Use in Hospitals with Different Levels of Complexity in Colombia: Findings from a Before-and-After Study and Suggestions for the Future.

In the collaborative efforts to control bacterial antimicrobial resistance (AMR), the challenge for many low- and middle-income countries currently lies in the adequate design and successful implementation and operation of different strategies aimed at improving antibiotic use during hospital care. This study aims to provide data on these different strategies in three hospitals with different levels of complexity and geographic locations in Colombia. This before-and-after study describes and analyzes the development and implementation of clinical practice guidelines (CPGs), continuing education courses, quick consultation tools, and antimicrobial stewardship programs (ASPs) with the use of telemedicine. This includes measuring indicators in the ASP framework such as adherence to CPGs and antibiotic consumption. We used five CPGs developed in the Colombian context. We designed and developed a Massive Open Online Course (MOOC) and a mobile application (app) as strategies for dissemination and implementation. The ASP was designed and implemented according to each institution's level of complexity. In the three hospitals, a progressive increase in adherence to the antibiotic recommendations proposed in the CPGs was observed, and there was a lower use of antibiotics with the ASPs, both in the general wards and ICUs. We concluded that in medium-complexity hospitals located in small rural cities, successful development of ASPs is possible when they are well-planned, implemented, and supported by the organization. It is necessary that Colombia and other Latin American countries continue activities that reduce AMR by designing, implementing, and improving these interventions throughout the national territory.

945. Development of Antimicrobial Stewardship Programs in Central and South America

Abstract Background There is a need to assess current development of hospital Antimicrobial Stewardship Programs (ASPs) in Latin America. Methods Cross-sectional evaluation of ASPs using a standardized and previously validated self-assessment tool derived from the Centers for Disease Control and Prevention Core Elements of Antibiotic Stewardship (AS). The assessment was deployed to 40 hospitals in Panama, Guatemala, Ecuador, Colombia, and Argentina in 3/2022 through a regional research network. The assessment included 94 questions, with each question including a graded response (meets criteria, partially meets criteria, does not meet criteria, and in some, not applicable). Results 22 public and 16 private hospitals completed the assessment (95% response rate), 10% and 25% of which were small hospitals (< 110 beds), respectively. 82% were academic, and all have an Infection Prevention and Control program/committee. >70% of ASPs have a physician and pharmacist involved, although 65% reported no salary support for AS activities. Only 13% and 29% of AS pharmacists and physicians, respectively, met recommended full-time equivalent/bed ratios; and 76% lacked information and technology (IT) support. 50% indicated the AS committee did not meet regularly, and another 50% reported not including non-AS physicians in the committee. Most hospitals have implemented prior-authorization and post-prescription review and feedback, with much fewer reporting a process to alert of duplicate therapy and use of auto-stops. 89% reported regular access to new antibiotics. While most hospitals monitor antibiotic consumption, few evaluate trends and/or appropriateness of use. Treatment guidelines for most common infections were missing in up to 50% of hospitals, especially in public hospitals. Most respondents indicated their hospitals promote teamwork, and in the vast majority, recommendations from AS are valued. Stratification of results by private and public hospitals in Table. Table:Results of a self-assessment of antimicrobial stewardship activities at the facility level in 38 hospitals in Latin America. Conclusion We found several opportunities for improvement, which differed between private and public hospitals. Common barriers to both settings include access to IT support; better pharmacist and physician resource allocation, education, and monitoring of process and outcomes measures. Disclosures Sara E.

940. First situational diagnosis of the implementation of Antimicrobial Stewardship Programs in Mexican Hospitals, 2021

Abstract Background The development of antimicrobial stewardship programs (ASP) can help to improve the quality of care and contain the growing problem of antimicrobial resistance (AMR). In Mexico, there is little evidence on the design, implementation and evaluation of hospital ASP. The objective of this study is to present a situational diagnosis of the ASP structure, processes implemented and monitoring of results obtained in a sample of Mexican hospitals. Methods An online survey directed to ASP teams was applied to a purposive sample of 40 hospitals that perform regular antimicrobial stewardship activities in Mexico, during the last trimester of 2021. The survey was based on the ‘core elements’ instruments developed by the CDC and WHO. Results Forty hospitals (62% public and 38% private) were surveyed in 13 states in Mexico regarding ASP basic elements. Infrastructure and Organization elements: on average 52% of these hospitals carry basic actions that refer to: written ASP document and annual plan (46%); allocated human resources (68%); availability of material resources (59%) and use of technological platforms (37%). Processes: development of hospital treatment guidelines (49%); educational interventions (40%); persuasive and feedback interventions (42%); and in greater proportion, restrictive interventions (77%). Monitoring activities: interventions (25%); antimicrobial consumption (73%) and AMR (85%) Conclusion This first diagnosis serves as a baseline to determine the current state of ASP implementation per hospital and in the country. It also reflects on the ASP heterogeneity, that should be addressed by national policies. The greatest challenge lies in the program governance, and the systematic monitoring of the implementation of ASP interventions. Disclosures Anahí Dreser, PhD, MSD: Grant/Research Support.

Nurses' attitudes toward antimicrobial stewardship in South Korea

Global concerns about antimicrobial resistance have accelerated the development of antimicrobial stewardship programmes (ASPs) to improve the safety and quality of clinical care. Nurses have important roles in antimicrobial stewardship (AS). To assess Korean nurses' attitudes toward AS and compare differences in nurses' attitudes toward antimicrobial use and resistance by organizational factors. This descriptive cross-sectional study analysed online survey data for 1142 nurses. Nurses' attitudes were compared by organizational factors using analysis of variance. Approximately half of the nurses reported that they were familiar with and knowledgeable about the term AS. Most of the respondents agreed that a strong knowledge of antimicrobials is essential, that ASPs are important in their healthcare settings, and that they should be involved in interventions to improve antimicrobial use. Nurses often relied on peer nurses or internet resources when questions arose about the care for infectious disease patients. Nurses working at large hospitals or those who had easy access to infectious disease specialists had more insightful attitudes about antimicrobial use and resistance. Hospitals need to provide educational programmes on the appropriate use of antimicrobials and antimicrobial resistance for nurses. Comprehensive approaches, including ASPs and contact systems with infectious disease specialists, could increase nurses' accessibility to scientific evidence regarding antimicrobial use. National-level approaches should be implemented to establish ASPs in healthcare settings with limited resources.

The use of common antimicrobial agents in US veal calves.

The use of antimicrobials in food animals and the selection of antimicrobial-resistant pathogens continue to be prominent concerns for human food safety and public health. To provide optimal stewardship programs, antimicrobial use in animal production operations must be quantified and standardized for benchmarking and creating goals, monitoring temporal trends, and identifying causes of emerging resistance. In the United States, quantified estimates of antimicrobial use are available in dairy and beef cattle, but these data have not been generated for veal calf herds. Therefore, the objective of this study was to estimate the treatment incidence (TI) of antimicrobials for eight US veal calf farms in one rearing cycle. Treatment incidences were compared between calculated doses defined by the labeled daily dose (LDD), animal-defined daily dose (ADD) from the European Medicines Agency (EMA) guideline, and the used daily dose (UDD) from the farm treatment protocols. Among eight farms, veal calves received a mean of 34.40 LDD, 34.88 ADD, and 28.68 UDD of an antimicrobial per 100days. The lower TI based on the UDD administration was a result of higher farm protocol dosing relative to the labeled and EMA daily doses. Higher quantities of antimicrobial administration were observed in the first three weeks (day 1-21) of rearing (Tukey-adjusted p<.05). This study is the first to quantitatively estimate the TI of antimicrobials on the US veal calf operations and serves as an important step toward the development of antimicrobial stewardship programs.

PATTERNS OF ANTIMICROBIAL RESISTANCE AMONG MAJOR BACTERIAL PATHOGENS ISOLATED FROM CLINICAL SAMPLES IN TWO TERTIARY’S HOSPITALS, IN SANA'A, YEMEN

Background and objectives: At the present time, antimicrobial resistance (AMR) is a major public health hazard, with antimicrobial resistance bacteria increasing exponentially. This study estimates the epidemiological profiles and antimicrobial resistance of Gram-positive bacteria (GPB) and Gram-negative bacteria (GNB) isolated from clinical samples among patients admitted to two University hospitals in Sana'a city for one year (2019). Methods: This was a retrospective study of clinical samples of patients collected from January 1, 2019 to December 30, 2019. All samples were appraised to determine presence of infectious agents using standard methods for isolation and identification of bacteria and yeasts from clinical samples of patients admitted to Al-Gumhouri University Hospital and Al-Kuwait University Hospital in Sana'a city. Antibiotic resistance was done using Kirby-Bauer disc diffusion methods. Results: 2,931 different pathogenic bacteria were detected from 24,690 different clinical specimens. The samples had an overall detection rate of 11.9% (2931/24,690). Among the bacterial pathogens isolated from clinical samples, 52.4% (n=1536) had GPB and 41.2% (n=1207) had GNB. The predominant GNB isolates were E.coli (22.04%), Klebsiella spp (6.03%), Pseudomonas aeruginosa (7.1%), Acinetobacter baumannii (1.46%), Enterobacter spp. (1.09%), Citrobacter spp. (1.16%), respectively. Among the GPB, S.aureus was the most common (26.3%), Coagulase-negative Staphylococcus (8.1%), Non-hemolytic Streptococcus (9.1%), Other alpha-hemolytic Streptococcus (3.9%), Streptococcus pyogenes (1.9%), and Streptococcus pneumoniae (0.5% ). A high rate of antibiotic resistance was recorded for sulfamethoxazole/trimethoprim (85.5%), ceftazidime (81.07%), ampicillin (70.4%), cefuroxime (66.4%). Conclusions: The current study results revealed that the rate of resistance between GNB and GPB is associated with the incidence of different infections in patients attending two major tertiary hospitals in Sana'a city is very high. These results indicate ongoing screening and follow-up programs to detect antibiotic resistance, and also suggest the development of antimicrobial stewardship programs in Sana'a, Yemen.

The best today for a better tomorrow: a standard of practice to both recognise and develop infectious diseases pharmacy

Infectious disease is a multidisciplinary specialty involving infectious diseases physicians, clinical microbiologists, nurses and pharmacists among other specialities. Given that so much of infectious diseases involves antimicrobial drugs, it is obvious that pharmacists are an integral part of the care of patients with infections. Infectious diseases pharmacy has developed as its own specialty over the last 10–15 years with the development of antimicrobial stewardship programs, which are now a requirement of hospital accreditation. For those of us that have the privilege of working with specialist ID pharmacists, there are few days that we would not call upon their expertise for difficult areas – HIV drug interactions, dosing in organ failure and critically ill patients, the more unusual antibiotic interactions, and hospital in the home programs, for example. Australian pharmacists have also contributed immensely to areas outside of direct clinical care. In research, The Australian newspaper named Prof Jason Roberts as the leading national researcher in the fields of both critical care and communicable diseases in 2019.1 Many other examples of the impact of pharmacists are provided in this document. Pharmacists have led the ongoing development of Australian national treatment guidelines, Therapeutic Guidelines, while providing key insights into quality and safety programs at state and national levels, as well as contributing to the National COVID-19 Evidence Task Force, among many other contributions. The SHPA Standard of Practice in Infectious Diseases for Pharmacy Services, published in this issue, crystallises the skills and scope that pharmacists have in the management of infectious diseases, particularly in providing clinical care but also into broader governance systems. These include ensuring the quality use of antimicrobials (through education, antimicrobial stewardship programs, developing and reviewing policies and procedures) and ensuring access through formulary policies. The immediate impact of the Standard is to form the basis for a curriculum for junior pharmacists intending to specialise in this area, or for general pharmacists who may require skills in this area in other settings, such as rural hospitals or community settings. Advanced training for physicians has evolved from an “apprenticeship” model to a more structured educational model. While most currently available post-graduate courses are international, a standardised curriculum should facilitate local training and education initiatives, analogous to accreditation developed for infection prevention and control nurses by the Australasian College of Infection Prevention and Control. Collaborative guidance such as this Standard will help future ID pharmacists to build on existing roles and extend into emerging areas of practice. It should be noted that like the scope of practice of pharmacists more generally, this will continue to evolve and expand over time. The infectious diseases community welcomes this major step in recognising the expertise of infectious diseases pharmacists and their contribution to clinical care and the systems that support healthcare. The author has no conflicts of interest to declare.

Barriers to implementing antimicrobial stewardship programs in three low- and middle-income country tertiary care settings: findings from a multi-site qualitative study

BackgroundAntimicrobial resistance has been named as one of the top ten threats to public health in the world. Hospital-based antimicrobial stewardship programs (ASPs) can help reduce antimicrobial resistance. The purpose of this study was to determine perceived barriers to the development and implementation of ASPs in tertiary care centers in three low- and middle-income countries (LMICs).MethodsInterviews were conducted with 45 physicians at tertiary care hospitals in Sri Lanka (n = 22), Kenya (12), and Tanzania (11). Interviews assessed knowledge of antimicrobial resistance and ASPs, current antimicrobial prescribing practices, access to diagnostics that inform antimicrobial use, receptiveness to ASPs, and perceived barriers to implementing ASPs. Two independent reviewers coded the interviews using principles of applied thematic analysis, and comparisons of themes were made across the three sites.ResultsBarriers to improving antimicrobial prescribing included prohibitively expensive antimicrobials, limited antimicrobial availability, resistance to changing current practices regarding antimicrobial prescribing, and limited diagnostic capabilities. The most frequent of these barriers in all three locations was limited drug availability. Many physicians in all three sites had not heard of ASPs before the interviews. Improved education was a suggested component of ASPs at all three sites. The creation of guidelines was also recommended, without prompting, by interviewees at all three sites. Although most participants felt microbiological results were helpful in tailoring antibiotic courses, some expressed distrust of laboratory culture results. Biomarkers like erythrocyte sedimentation rate and c-reactive protein were not felt to be specific enough to guide antimicrobial therapy. Despite limited or no prior knowledge of ASPs, most interviewees were receptive to implementing protocols that would include documentation and consultation with ASPs regarding antimicrobial prescribing.ConclusionsOur study highlighted several important barriers to implementing ASPs that were shared between three tertiary care centers in LMICs. Improving drug availability, enhancing availability of and trust in microbiologic data, creating local guidelines, and providing education to physicians regarding antimicrobial prescribing are important steps that could be taken by ASPs in these facilities.

Finding the path of least resistance: Locally adapting the MITIGATE toolkit in emergency departments and urgent care centers.

The MITIGATE toolkit was developed to assist urgent care and emergency departments in the development of antimicrobial stewardship programs. At the University of Washington, we adopted the MITIGATE toolkit in 10 urgent care centers, 9 primary care clinics, and 1 emergency department. We encountered and overcame challenges: a complex data build, choosing feasible outcomes to measure, issues with accurate coding, and maintaining positive stewardship relationships. Herein, we discuss solutions to challenges we encountered to provide guidance for those considering using this toolkit.

166. Barriers to implementing antimicrobial stewardship programs in low- or middle-income country settings: findings from a multi-site qualitative study

BackgroundAntimicrobial resistance has been named as one of the top ten threats to health in the world. The World Health Organization has endorsed the implementation of hosptial-based antimicrobial stewardship programs (ASPs) to reduce antimicrobial resistance. We conducted a qualitative study to determine perceived barriers to the development and implementation of ASPs in low- and middle-income countries (LMICs).MethodsWe conducted 46 interviews with medical doctors at tertiary care hospitals in Sri Lanka (22 doctors), Kenya (12), and Tanzania (12). Interviews assessed knowledge and receptiveness to ASPs and barriers to implementing ASP protocols. Interviews were conducted in English, audio recorded, and transcribed. The interviews discussed knowledge of antimicrobial resistance and ASPs, current antimicrobial prescribing practices, access to diagnostics, receptiveness to ASPs, and perceived barriers to implementing ASPs. Data analysis followed procedures of applied thematic analysis, and used NVivo software. A codebook included structural themes based on the interview questions and emerging inductive themes. Two independent reviewers coded the interviews, and the coding was combined and reviewed for consensus. Themes were synthesized, with comparisons made across the three sites.ResultsMedical doctors from all three sites discussed multiple barriers to improving antimicrobial prescribing: prohibitively expensive antimicrobials, limited antimicrobial availability, resistance to change current practices regarding antimicrobial prescribing, and limited diagnostic data. The most frequent of these barriers discussed in all three locations was limited drug availability, mentioned by 12/22 physicians in Sri Lanka, 5/12 in Tanzania and 8/12 in Kenya. Improved education was a suggested component of ASPs in all three sites: 7/22 in Sri Lanka, 6/12 in Tanzania, and 6/12 in Kenya.ConclusionThe study highlighted several important issues in determining the next steps for the implementation of ASPs in these LMIC hospitals. Improving drug availability and improving education to change physicians’ antimicrobial prescribing practices are important targets that could be addressed by ASPs in these facilities.Disclosures All Authors: No reported disclosures

Antimicrobial Stewardship Practice in the Ambulatory Setting From a National Cohort.

BackgroundThe majority of antimicrobial use occurs in the ambulatory setting. Antimicrobial stewardship programs (ASPs) are effective in improving appropriate prescribing and are now required by accreditation bodies.MethodsThis was a cross-sectional, multicenter survey describing the current state of ambulatory ASPs in a national cohort of Vizient member hospitals with ambulatory healthcare settings and serves as a benchmark for stewardship strategies related to program effectiveness.ResultsOne hundred twenty-nine survey responses from a variety of institution types across 44 states were received. Survey respondents reported a fully functioning ASP in 7% (9 of 129) of ambulatory practices compared with 88% (114 of 129) of inpatient institutions. Effectiveness in at least 1 antibiotic use-related outcome (ie, utilization, resistance, Clostridioides difficile infection, or cost) in the past 2 years was reported in 18% (18 of 100) of ambulatory and 84% (103 of 123) of inpatient ASPs. Characteristics of ambulatory ASPs demonstrating effectiveness were institution guidelines (89%, 16 of 18), rapid diagnostic testing for respiratory viruses or group A Streptococcus (89% 16 of 18), outpatient antibiograms (78% 14 of 18), and dedicated pharmacist support (72%, 13 of 18). Ambulatory ASP effectiveness was shown to increase as programs met more of the Centers for Disease Control and Prevention (CDC) Core Elements of Outpatient Antimicrobial Stewardship (P < .001).ConclusionsAntimicrobial stewardship programs are needed in the ambulatory setting, but they are not common. Currently, few ambulatory ASPs in this survey self-identify as fully functioning. The CDC Core Elements of antimicrobial stewardship should remain foundational for ASP development and expansion.

Effect of Short-Term Carbapenem Restriction on Antimicrobial Susceptibility of Resistant Gram-Negative Bacilli in an ICU

Background: Carbapenem-resistant GNB infections are a serious public health problem worldwide, particularly due to the high mortality associated with them and the low number of therapeutic options. One approach to this challenge is the development of antimicrobial stewardship programs. Objective: We evaluated the impact of a carbapenem restriction program on reducing of bacterial resistance in an intensive care unit (ICU). Methods: A retrospective study conducted in 2 phases in the 80-bed ICU of an acute-care public hospital in Minas Gerais, Brazil. The preintervention phase lasted 16 months (January 2018–April 2019) and the second phase (carbapenem restriction), after the intervention, lasted 4 months (May–August 2019). The intervention was defined as carbapenem-sparing and the use of meropenem was authorized in 3 situations: (1) treatment of serious infections documented by extended-spectrum β-lactamase–producing Enterobacteriacea (ESBL); (2) therapeutic failure with the use of another antimicrobial; and (3) infectious disease recommendation. Data were obtained through consultation of electronic medical records and microbiological results, as standardized by the CLSI, for patients with a &gt;48-hour stay in the ICU and who met the criteria for healthcare-associated infection (HAI) according to the CDC NHSN definition. Results: Before the intervention, on average, 50 cultures were obtained with positive results for multidrug-resistant GNB–MER-GNB (SD, 12.2) and in the intervention phase, this number was 31 cultures (SD, 12.8; P = .010). Average carbapenem consumption decreased significantly with corresponding increase in cefepime consumption in the same period (Fig. 1). The ATB (DDD per 1,000 patient days) before the intervention for carbapenems was 110.6 (SD, 97.1) and for cefepime was 8.2 (SD, 5.9). In the intervention phase, the ATB for carbapenems was 44.7 (SD, 38.5; P = .015) and for cefepime it was 32.0 (SD, 20.3; P &lt; .001). In terms of multidrug resistance rate, before the intervention, 95 of 149 of Acinetobacter (64%) were resistant and during the intervention, 13 of 30 Acinetobacter (43%) were resistant (P = .043). Other GNB (Klebsiella, Proteus, Escherichia coli, and Pseudomonas) reduced the resistance rate, but without statistical significance. We observed a reduction in the HAI rate per MDR-GNB (Fig. 2): before the intervention, it was 22.7 (SD, 5.5) and during the intervention phase it was 16.5 (SD, 7.7; P = .07), although this change did not reach statistical significance. Nevertheless, the ICU Klebsiella infection rate did significantly decrease; it was 5.5 (SD, 1.9) before the intervention and 2.4 (SD, 1.8) after the intervention (P = .009). Conclusions: Short-term carbapenem restriction may be an effective strategy to reduce the incidence of carbapenem-resistant GNB infections in the ICU. The scarce arsenal available for the treatment of MDR-GNB and the high mortality rate justify the growing need for stewardship programs in Brazilian ICUs.Funding: NoneDisclosures: None

Implementation of an Antimicrobial Stewardship Program in Five Colombian Hospitals in 2018

Background: More than 50% of antibiotics used in hospitals are unnecessary or inappropriate. The antimicrobial stewardship programs (ASPs) are coordinated efforts to promote the rational and effective use of antibiotics including appropriate selection, dosage, administration, and duration of therapy. When an ASP integrates infection control strategies, it is possible to decrease the transmission of multidrug-resistant pathogens. Methods: In 2018, 5 Colombian hospitals were selected to implement an ASP. Private and public hospitals from different cities were included in the study, ranging from 200 to 700 beds. Our team, consisting of an infectious disease and hospital epidemiologist, visited each hospital to establish the baseline of their ASP program, to define the ASP outcomes according to each hospital’s needs, and to set goals for ASP outcomes in the following 6–12 months. Follow-up was scheduled every 2 months through Skype video conference. The baseline diagnosis or preintervention evaluation was done using a tool adapted from previous reports (ie, international consensus and The Joint Commission international standards). Documentation related to ASPs, such as microbiological profiles, antimicrobial guidelines (AMG) and indicators for the adherence to them as well as antimicrobial resistance (AMR) prevention through protocols, were written and/or updated. Prevention and infection control requirements and protocols were also updated, and cleaning and antiseptic policies were created. Training in rational use of antibiotic, infection control and prevention, and cleaning and disinfection were carried out with the healthcare workers in each institution. Results: Before the intervention, the development of the ASP according to the tool was 27% (range, 5%–47%). The lowest institutional scores were the item related to ASP feedback and reports (11% on average), followed by education and training (14%), defined ASP responsibilities (23%), ASP function according to priorities (26%), and AMR surveillance (27%). After the intervention, the ASP development increased to 57% (range, 39%–81%) in the hospitals. The highest scores achieved were for education and training (90%), surveillance (75%), and the activities of the infection control committee (70%). The items that made the greatest contribution to ASP development were the individual antibiogram, including the bacteria resistance profile, and the development of the AMG based on the local epidemiology in each hospital. Conclusions: The implementation of an ASP should include training and education as well as defining outcomes according to the hospital’s needs. Once the strategy is implemented, follow-up is key to achieving the goals.Funding: NoneDisclosures: None

Development of Antimicrobial Stewardship Programmes in Low and Middle-Income Countries: A Mixed-Methods Study in Nigerian Hospitals.

Antimicrobial resistance (AMR) is a major concern facing global health today, with the greatest impact in developing countries where the burden of infectious diseases is much higher. The inappropriate prescribing and use of antibiotics are contributory factors to increasing antibiotic resistance. Antimicrobial stewardship programmes (AMS) are implemented to optimise use and promote behavioural change in the use of antimicrobials. AMS programmes have been widely employed and proven to improve antibiotic use in many high-income settings. However, strategies to contain antimicrobial resistance have yet to be successfully implemented in low-resource settings. A recent toolkit for AMS in low- and middle-income countries by the World Health Organisation (WHO) recognizes the importance of local context in the development of AMS programmes. This study employed a bottom-up approach to identify important local determinants of antimicrobial prescribing practices in a low-middle income setting, to inform the development of a local AMS programme. Analysis of prescribing practices and interviews with prescribers highlighted priorities for AMS, which include increasing awareness of antibiotic resistance, development and maintenance of guidelines for antibiotic use, monitoring and surveillance of antibiotic use, ensuring the quality of low-cost generic medicines, and improved laboratory services. The application of an established theoretical model for behaviour change guided the development of specific proposals for AMS. Finally, in a consultation with stakeholders, the feasibility of the plan was explored along with strategies for its implementation. This project provides an example of the design, and proposal for implementation of an AMS plan to improve antibiotic use in hospitals in low-middle income settings.

Challenges in the Diagnosis and Management of Bacterial Lung Infections in Solid Organ Recipients: A Narrative Review.

Respiratory infections pose a significant threat to the success of solid organ transplantation, and the diagnosis and management of these infections are challenging. The current narrative review addressed some of these challenges, based on evidence from the literature published in the last 20 years. Specifically, we focused our attention on (i) the obstacles to an etiologic diagnosis of respiratory infections among solid organ transplant recipients, (ii) the management of bacterial respiratory infections in an era characterized by increased antimicrobial resistance, and (iii) the development of antimicrobial stewardship programs dedicated to solid organ transplant recipients.
