Knowledge, attitudes and perceptions of Latin American healthcare workers relating to antibiotic stewardship and antibiotic use: a cross-sectional multi-country study.

BACKGROUND: The burden of antimicrobial resistance (AMR) in Latin America is high. Little is known about healthcare workers' (HCWs) knowledge, attitudes, and perceptions of antimicrobial stewardship (AS), AMR, and antibiotic use (AU) in the region. METHODS: HCWs from 42 hospitals from 5 Latin American countries were invited to take an electronic, voluntary, anonymous survey regarding knowledge, attitudes, and perceptions of AS, AMR, and AU between March-April 2023. FINDINGS: Overall, 996 HCWs completed the survey (52% physicians, 32% nurses, 11% pharmacists, 3% microbiologists, and 2% "other"). More than 90% of respondents indicated optimizing AU was a priority at their healthcare facility (HCF), 69% stated the importance of AS was communicated at their HCF, and 23% were unfamiliar with the term "antibiotic stewardship". Most (> 95%) respondents acknowledged that appropriate AU can reduce AMR; however, few thought AU (< 30%) or AMR (< 50%) were a problem in their HCF. Lack of access to antibiogram and to locally endorsed guidelines was reported by 51% and 34% of HCWs, respectively. Among prescribers, 53% did not consider non-physicians' opinions to make antibiotic-related decisions, 22% reported not receiving education on how to select antibiotics based on culture results and 60% stated patients and families influence their antibiotic decisions. CONCLUSIONS: Although HCWs perceived improving AU as a priority, they did not perceive AU or AMR as a problem in their HCF. AS opportunities include improved access to guidelines, access to AMR/AU data, teamwork, and education on AS for HCWs and patients and families.

Knowledge and attitude of healthcare prescribers and pharmacists toward antimicrobial stewardship program and the barriers for its implementation.

BACKGROUND: Antimicrobial stewardship (ASP) is considered a key prevention strategy in addressing the worldwide concern of accelerating antimicrobial resistance. Limited research is available regarding healthcare providers' knowledge and attitude toward antimicrobial stewardship and the barriers for its implementation. METHODS: The present cross-sectional study was conducted on pharmacists and healthcare prescribers (HCPs) in different hospital sites across Jordan. A validated survey was used to evaluate HCPs and pharmacists' knowledge, and attitudes towards ASP and the barriers for its implementation. Logistic and linear regression were conducted to identify the factors associated with knowledge and attitude toward ASP, respectively. RESULTS: A total of 603 participants, 69 (11.4%) pharmacists and 534 (88.6%) HCPs completed the study questionnaire, with a response rate of 80.4%. The overall mean knowledge about ASP was 7.16 out of 10, ranging from 0 to 10 (SD 2.22). Being a pharmacist and increased awareness/familiarity about ASP were associated with improved ASP knowledge. The overall average attitude score was = 3.8 ± 0.49 (range: 1.8-4.8). Results revealed that being a pharmacist and improved knowledge were associated with improved attitude toward ASP. Lack of specialized staff with expertise in ASP and lack of access to education and training programs were the major barriers hinder ASP implementation. CONCLUSION: Despite the reasonable knowledge and the positive attitude toward the ASP, several barriers were reported, particularly by the pharmacists. Therefore, promoting the presence of adequately skilled healthcare personnel, creating easily accessible online courses, and establishing a comprehensive database of ASP resources are all suggested approaches to improve the application of ASP in healthcare settings.

Implementation of an antimicrobial stewardship program for urinary tract infections in long-term care facilities: a cluster-controlled intervention study.

BACKGROUND: Widespread inappropriate use of antimicrobial substances drives resistance development worldwide. In long-term care facilities (LTCF), antibiotics are among the most frequently prescribed medications. More than one third of antimicrobial agents prescribed in LTCFs are for urinary tract infections (UTI). We aimed to increase the number of appropriate antimicrobial treatments for UTIs in LTCFs using a multi-faceted antimicrobial stewardship intervention. METHODS: We performed a non-randomized cluster-controlled intervention study. Four LTCFs of the Geriatric Health Centers Graz were the intervention group, four LTCFs served as control group. The main components of the intervention were: voluntary continuing medical education for primary care physicians, distribution of a written guideline, implementation of the project homepage to distribute guidelines and videos and onsite training for nursing staff. Local nursing staff recorded data on UTI episodes in an online case report platform. Two blinded reviewers assessed whether treatments were adequate. RESULTS: 326 UTI episodes were recorded, 161 in the intervention group and 165 in the control group. During the intervention period, risk ratio for inadequate indication for treatment was 0.41 (95% CI 0.19-0.90), p = 0.025. In theintervention group, the proportion of adequate antibiotic choices increased from 42.1% in the pre-intervention period, to 45.9% during the intervention and to 51% in the post-intervention period (absolute increase of 8.9%). In the control group, the proportion was 36.4%, 33.3% and 33.3%, respectively. The numerical difference between intervention group and control group in the post-intervention period was 17.7% (difference did not reach statistical significance). There were no significant differences between the control group and intervention group in the safety outcomes (proportion of clinical failure, number of hospital admissions due to UTI and adverse events due to antimicrobial treatment). CONCLUSIONS: An antimicrobial stewardship program consisting of practice guidelines, local and web-based education for nursing staff and general practitioners resulted in a significant increase in adequate treatments (in terms of decision to treat the UTI) during the intervention period. However, this difference was not maintained in the post-intervention phase. Continued efforts to improve the quality of prescriptions further are necessary. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov NCT04798365.

[Combating antimicrobial resistance: audits of practices to target actions]. / Lutte contre l'antibiorésistance : audits des pratiques pour cibler les actions.

Antibiotic resistance is a public health emergency requiring a concerted approach and motivating the implementation of antibiotic stewardship programmes. As part of an institutional project at the Centre hospitalier universitaire vaudois, we collected data on the appropriateness of antimicrobial prescriptions in various medical and surgical departments in order to identify areas for improvement. The results show that there is room for improvement and that there are differences between departments, particularly regarding surgical prophylaxis administered beyond the operating time, adaptation of the spectrum and duration. Prescribing appropriateness data is an essential complement to consumption data for adapting effective intervention strategies.

L'antibiorésistance constitue une urgence de santé publique justifiant une approche concertée et motivant la mise en place de programmes de gestion des antibiotiques (Antibiotic Stewardship). Dans le cadre d'un projet institutionnel conduit au Centre hospitalier universitaire vaudois, nous avons collecté dans différents services médico-chirurgicaux des données d'adéquation des prescriptions afin d'identifier les domaines d'amélioration. Les résultats obtenus montrent qu'il existe une marge d'amélioration et des différences interservices, en particulier concernant les prophylaxies chirurgicales administrées au-delà du temps opératoire, l'adaptation du spectre et la durée. Les données d'adéquation des prescriptions sont un complément essentiel aux données de consommation pour adapter des stratégies d'intervention efficaces.

The Diagnosis and Treatment of Adult Urinary Tract Infections in the Emergency Department.

Emergency medicine has been called the art of "making complicated clinical decisions with limited information." This description is particularly relevant in the case of diagnosis and treatment of urinary tract infections (UTIs). Although common, UTIs are often challenging to diagnose given the presence of non-specific signs and symptoms and over-reliance on laboratory findings. This review provides an interdisciplinary interpretation of the primary literature and practice guidelines, with a focus on diagnostic and antimicrobial stewardship in the emergency department.

Optimizing Antimicrobial Stewardship in the Emergency Department.

Antibiotic stewardship is a core component of emergency department (ED) practice and impacts patient safety, clinical outcomes, and public health. The unique characteristics of ED practice, including crowding, time pressure, and diagnostic uncertainty, need to be considered when implementing antibiotic stewardship interventions in this setting. Rapid advances in pathogen detection and host response biomarkers promise to revolutionize the diagnosis of infectious diseases in the ED, but such tests are not yet considered standard of care. Presently, clinical decision support embedded in the electronic health record and pharmacist-led interventions are the most effective ways to improve antibiotic prescribing in the ED.

Diseño de un panel de indicadores para programas de optimización del uso de antimicrobianos en los Servicios de Urgencias / Design of a panel of indicators for antibiotic stewardship programs in the Emergency Department

Objetivo: desarrollar un panel de indicadores para monitorizar la actividad de los programas de optimización del uso de antimicrobianos en los servicios de urgencias. Métodos: un grupo multidisciplinar formado por expertos en el manejo de la infección en urgencias y en la implantación de programas de optimización de uso de antimicrobianos (PROA) evaluó una propuesta de indicadores utilizando una metodología Delphi modificada. En una primera ronda, cada uno de los expertos clasificó la relevancia de cada indicador propuesto en 2 dimensiones (repercusión asistencial y facilidad de implantación) y 2 atributos (nivel de priorización y periodicidad de medida). La segunda ronda se realizó a partir del cuestionario modificado de acuerdo con las sugerencias planteadas y nuevos indicadores sugeridos por los participantes. Los expertos efectuaron modificaciones en el orden de priorización y calificaron los nuevos indicadores propuestos de la misma manera que en la primera ronda. Resultados: se propusieron un total de 61 potenciales indicadores divididos en 4 grupos: indicadores de consumo, microbiológicos, de proceso y de resultado. Tras el análisis de las puntuaciones y los comentarios realizados en la primera ronda, 31 indicadores fueron clasificados como de alta prioridad, 25 de prioridad intermedia y 5 de baja prioridad. Además se generaron 19 nuevos indicadores. Tras la segunda ronda, se mantuvieron los 61 indicadores inicialmente propuestos y adicionalmente se incorporaron 18 nuevos: 11 como de alta prioridad, 3 como de intermedia y 4 como de baja prioridad. Conclusiones: los expertos consensuaron un panel de indicadores PROA adaptado a los servicios de urgencias priorizados por nivel de relevancia como un elemento de ayuda para el desarrollo de estos programas, que contribuirá a monitorizar la adecuación del uso de antimicrobianos en estas unidades.(AU)

Objective: To develop a panel of indicators to monitor antimicrobial stewardship programs activity in the emergency department. Methods: A multidisciplinary group consisting of experts in the management of infection in emergency departments and the implementation of antimicrobial stewardship programs (ASP) evaluated a proposal of indicators using a modified Delphi methodology. In the first round, each expert classified the relevance of each proposed indicators in two dimensions (healthcare impact and ease of implementation) and two attributes (prioritization level and frequency). The second round was conducted based on the modified questionnaire according to the suggestions raised and new indicators suggested. Experts modified the prioritization order and rated the new indicators in the same manner as in the first round. Results: 61 potential indicators divided into four groups were proposed: consumption indicators, microbiological indicators, process indicators, and outcome indicators. After analyzing the scores and comments from the first round, 31 indicators were classified as high priority, 25 as intermediate priority, and 5 as low priority. Moreover, 18 new indicators were generated. Following the second round, all 61 initially proposed indicators were retained, and 18 new indicators were incorporated: 11 classified as high priority, 3 as intermediate priority, and 4 as low priority. Conclusions: The experts agreed on a panel of ASP indicators adapted to the emergency services prioritized by level of relevance. This is as a helpful tool for the development of these programs and will contribute to monitoring the appropriateness of the use of antimicrobials in these units.(AU)

Programas de optimización del uso de antimicrobianos en los servicios de urgencias españoles: Estudio PROA-URG / Antibiotic stewardship programs in the Spanish emergency services: PROA-URG Study

Introducción: Los programas de optimización de antimicrobianos (PROA) son herramientas clave en la adecuación de estos fármacos. La información disponible sobre la aplicación e indicadores para monitorizar estos programas en urgencias es limitada. El objetivo del estudio es conocer el grado de implantación de programas PROA en los servicios de urgencias, así como el uso de antimicrobianos en estas unidades. Material y métodos. Estudio multicéntrico retrospectivo. Se envió una invitación a todos los participantes del grupo de trabajo de farmacéuticos de urgencias REDFASTER-SEFH. Se utilizó un cuestionario de 21 ítems, contestado por un equipo formado por especialistas en los servicios de farmacia hospitalaria, urgencias, enfermedades infecciosas y microbiología. Resultados. 18 hospitales completaron la encuesta. Catorce (77,8%) disponían de un responsable PROA en la unidad. El valor de DDD por 1000 ingresos osciló entre 36,5 y 400,5 (mediana 100,4 [RIQ:57,2-157,3]). El grupo de carbapenémicos y macrólidos presentó una amplia variabilidad. Únicamente seis (33,3%) hospitales disponían de informe anual de resistencias específico para urocultivos y hemocultivos en urgencias. El porcentaje de multirresistentes en urocultivos fue del 12,5% y en hemocultivos del 12,2%. El porcentaje de adecuación en bacteremia de acuerdo con el resultado del hemocultivo fue del 81,0% (RIQ:74,6-85,0%), y en infección urinaria del 78,0% (RIQ:71,5-88,0%). Conclusiones. Pese a la existencia de responsables PROA, actividades formativas y guías de tratamiento en urgencias, la información sobre el uso de antimicrobianos y el perfil de resistencias en estas unidades es limitado. Futuras actividades han de ir encaminadas a mejorar la información sobre los resultados PROA propios para estas unidades. (AU)

Introduction: Antimicrobial stewardship programs (ASP) have become a key tool in the adaptation of these drugs to the health system. The information available on the application and indicators used in these programs in emergency departments is scarce. The objective of this study is to know theextent of ASP implementation in the emergency departments, as well as the use of antimicrobials in these units. Material and methods. Multicenter retrospective study. An invitation was sent to all participants of the REDFASTER-SEFH emergency pharmacist working group. A questionnaire was used consisting of 21 items, answered by a team made up of a pharmacist, emergency room specialist, infectious disease specialist and microbiologist. Results. Eighteen hospitals completed the survey. Fourteen (77.8%) had an ASP manager. The DDD value per 1000 admissions ranged between 36.5 and 400.5 (median: 100.4 [IQR:57.2-157.3]). Both carbapenem and macrolide group presented wide variability in use. Six (33.3%) hospitals had an annual report on the specific resistance profile for urine and blood cultures. The percentage of multi-drug resistant strains in urine cultures was 12.5% and in blood cultures 12.2%. The percentage of adequacy in the bacteremia treatment was 81.0% (IQR:74.6-85.0%), while in urinary tract infections was 78.0% (IQR:71.5-88.0). Conclusions: Despite the existence of ASP members in emergency services, as well as the training activity and local guidelines is common. knowledge of the use of antimicrobials and resistances is limited. Future activities must be aimed at improving information about the ASP results in these units. (AU)

Management of Chronic Osteomyelitis and Antibiotic Stewardship; An Effort to Delay the Post-Antibiotic Era.

OBJECTIVE: To develop an effective antimicrobial strategy for the management of chronic osteomyelitis. STUDY DESIGN: Observational study. Place and Duration of the Study: Departments of Microbiology and Orthopaedics, Combined Military Hospital Malir, Karachi, Pakistan, from January 2021 to February 2022. METHODOLOGY: Bone biopsies of 45 enrolled participants were taken for microbiological evaluation. Intravenous antibiotic therapy was begun as per empirical therapy based on the local antibiogram and antibiotic policy. Once the susceptibility pattern was available, targeted therapy started and continued for 28 to 42 days. Patients were evaluated based on inflammatory markers and clinical conditions for a minimum of six months to a maximum of one year. RESULTS:  Out of the 45 patients, the majority 29% were soldiers, 40% belonging to the age group of 31-60 years. The common predisposing factor was trauma/fractures followed by diabetes and implants leading to chronic sinus discharge and decubitus ulcers. The most commonly isolated organism was Staphylococcus aureus (38%) followed by Methicillin-resistant Staphylococcus aureus (MRSA) (31%). Cotrimoxazole and Rifampicin turned out to be good treatment options. Only 4.4% showed unsatisfactory prognosis, nonetheless, no mortality was observed during the course of treatment. CONCLUSION: In this study, highly resistant strains were observed with limited treatment options for chronic osteomyelitis, however, effective stewardship programmes with accurate diagnostic reporting and judicious use of antimicrobials can prevent overuse of the valuable resources. KEY WORDS: Antimicrobial stewardship, Osteomyelitis, Methicillin-resistant Staphylococcus aureus, Empirical therapy, Antimicrobial resistance.

Antimicrobial stewardship hindered by inadequate biosecurity and biosafety practices, and inappropriate antibiotics usage in poultry farms of Nepal-A pilot study.

Nepal's poultry industry has experienced remarkable growth in the last decade, but farm biosafety and biosecurity measures are often overlooked by farmers. As a result, farms often suffer from sporadic and regular outbreaks of many diseases, impacting production and creating public health challenges. Poor management practices, including overuse of antibiotics for prophylaxis and therapeutics, can enhance the spread of poultry diseases by propagating antimicrobial resistance (AMR) that is threatening poultry and human health. We assessed biosafety, biosecurity risks and AMR stewardship in sixteen poultry farms located in four districts: Ramechhap, Nuwakot, Sindhupalchowk, and Kavre. Risk assessment and AMR stewardship evaluation questionnaires were administered to formulate biosafety and biosecurity compliance matrix (BBCM). Risk assessment checklist assessed facility operations, personnel and standard operating procedures, water supply, cleaning and maintenance, rodent/pest control and record keeping. Oral and cloacal samples from the poultry were collected, pooled, and screened for eight poultry pathogens using Polymerase Chain Reaction (PCR) tests. Based on BBCM, we identified the highest BBCM score of 67% obtained by Sindhupalchowk farm 4 and the lowest of 12% by Kavre farm 3. Most of the farms (61.6%) followed general poultry farming practices, only half had clean and well-maintained farms. Lowest scores were obtained for personnel safety standard (42.4%) and rodent control (3.1%). At least one of the screened pathogens were detected in all farms. Mycoplasma gallisepticum was the most common pathogen detected in all but three farms, followed by Mycoplasma synoviae. More than half of the farmers considered AMR a threat, over 26% of them used antibiotics as a preventive measure and 81% did not consider withdrawal period for antibiotics prior to processing of their meat products. Additionally, antibiotics classified as "Watch" and "Restrict" by the WHO were frequently used by the farmers to treat bacterial infections in their farms.

Role of infrastructure and operation in disease prevalence in dairy farms: groundwork for disease prevention-based antibiotic stewardship.

Attempts at regulating misuse of antibiotics in the dairy industry have been ineffective, especially in low- and middle-income countries, who also typically have high burden of preventable infectious disease, we propose a disease prevention-based approach to minimize the need and in turn consumption of antibiotics in dairy farms. Since the immediate environment of the animals is key to disease prevalence, we targeted the infrastructure- and operation-related factors in dairy farms and their link with prevalence of most common diseases and symptoms. We conducted four focused group discussions and a cross-sectional survey in 378 dairy farms to investigate disease prevalence and associated infrastructural (housing system, and manger shape), and operational (waste management, feed management, and type of cleaning agent) parameters. The most common diseases (Mastitis and secondary infections related to Foot-and-mouth disease) and symptoms (fever and diarrhoea) in the focus area were linked with the infrastructural and operational factors on the dairy farm with higher disease prevalence reported in dairy farms, where the animals were exposed to variations in diurnal temperatures or were hard to clean. We further used ML classifiers - Neural Network (NN), k-Nearest Neighbour (kNN), Support Vector Machine (SVM), Decision Tree (DT), and Random Forest (RF) - to corroborate the relationship between infrastructure and operations of the dairy farms and disease prevalence- The DT classifier on randomly sampled data could predict the prevalence of the two most common diseases (accuracy = 92%, F1-score = 0.919) Our results open new avenues for cost-effective interventions such as use of curve-edged mangers, use of rubber mats on floors, not reusing leftover feed etc. in dairy farms to prevent the most common diseases and symptoms in dairy farms and reduce the need and consumption of antibiotics.

Health Care Workers Online YouTube Content Compared to AUA Prevention of Recurrent Urinary Tract Infections in Women Guidelines: An Integrative Review of Quality and Comprehensiveness Analysis.

INTRODUCTION: We document the quality, veracity, and comprehensiveness of recurrent UTI information on YouTube to increase health care workers' (HCWs') awareness of UTI-related content online, and to identify deficits in understanding, clarify misconceptions, and reduce stigmatization risk. METHODS: High-traffic topic search terms were curated by Google Trends to extract 200 videos, of which 45 met inclusion criteria. Five independent reviewers used a standardized questionnaire based on the AUA recurrent UTI guidelines to assess the definition of UTI, marketing content, prophylaxis/prevention strategies, and antibiotic use/stewardship. RESULTS: Incongruent or incomplete guideline UTI definitions were found in 78% (35/45) of videos (K = 0.40), despite 80% (36/45) being authored by HCWs. Forty-two percent (19/45) promoted nonguideline-based hygiene practices; 25% (11/45) advocated front-to-back wiping (K = 0.71). Descriptors identified within the videos included the mention of women with UTI as unclean. Only 55% (25/45) discussed increasing fluid intake (K = 0.59), while 33% (15/45) discussed the use of cranberry supplementation (K = 0.81). CONCLUSIONS: Discussion of hygiene practices which lack a specific guideline statement is particularly evident. Descriptors that characterize women with UTI as "unclean" may create a health equity concern for women experiencing UTIs. These findings should alert HCWs to the scope and emphasis in online education that patients may view to self-educate; both the errors and the issues of equity are problematic. Educational materials on UTI should be based on evidence-based guidelines, such as those by the AUA.

CDC's Hospital-Onset Clostridioides difficile Prevention Framework in a Regional Hospital Network.

Importance: Despite modest reductions in the incidence of hospital-onset Clostridioides difficile infection (HO-CDI), CDI remains a leading cause of health care-associated infection. As no single intervention has proven highly effective on its own, a multifaceted approach to controlling HO-CDI is needed. Objective: To assess the effectiveness of the Centers for Disease Control and Prevention's Strategies to Prevent Clostridioides difficile Infection in Acute Care Facilities Framework (hereafter, the Framework) in reducing HO-CDI incidence. Design, Setting, and Participants: This quality improvement study was performed within the Duke Infection Control Outreach Network from July 1, 2019, through March 31, 2022. In all, 20 hospitals in the network participated in an implementation study of the Framework recommendations, and 26 hospitals did not participate and served as controls. The Framework has 39 discrete intervention categories organized into 5 focal areas for CDI prevention: (1) isolation and contact precautions, (2) CDI confirmation, (3) environmental cleaning, (4) infrastructure development, and (5) antimicrobial stewardship engagement. Exposures: Monthly teleconferences supporting Framework implementation for the participating hospitals. Main Outcomes and Measures: Primary outcomes were HO-CDI incidence trends at participating hospitals compared with controls and postintervention HO-CDI incidence at intervention sites compared with rates during the 24 months before the intervention. Results: The study sample included a total of 2184 HO-CDI cases and 7 269 429 patient-days. In the intervention cohort of 20 participating hospitals, there were 1403 HO-CDI cases and 3 513 755 patient-days, with a median (IQR) HO-CDI incidence of 2.8 (2.0-4.3) cases per 10 000 patient-days. The first analysis included an additional 3 755 674 patient-days and 781 HO-CDI cases among the 26 controls, with a median (IQR) HO-CDI incidence of 1.1 (0.7-2.7) case per 10 000 patient-days. The second analysis included an additional 2 538 874 patient-days and 1751 HO-CDI cases, with a median (IQR) HO-CDI incidence of 5.9 (2.7-8.9) cases per 10 000 patient-days, from participating hospitals 24 months before the intervention. In the first analysis, intervention sites had a steeper decline in HO-CDI incidence over time relative to controls (yearly incidence rate ratio [IRR], 0.79 [95% CI, 0.67-0.94]; P = .01), but the decline was not temporally associated with study participation. In the second analysis, HO-CDI incidence was declining in participating hospitals before the intervention, and the rate of decline did not change during the intervention. The degree to which hospitals implemented the Framework was associated with steeper declines in HO-CDI incidence (yearly IRR, 0.95 [95% CI, 0.90-0.99]; P = .03). Conclusions and Relevance: In this quality improvement study of a regional hospital network, implementation of the Framework was not temporally associated with declining HO-CDI incidence. Further study of the effectiveness of multimodal prevention measures for controlling HO-CDI is warranted.

Decreasing Prescribing Errors in Antimicrobial Stewardship Program-Restricted Medications.

OBJECTIVES: Antimicrobial stewardship programs (ASPs) restrict prescribing practices to regulate antimicrobial use, increasing the risk of prescribing errors. This quality improvement project aimed to decrease the proportion of prescribing errors in ASP-restricted medications by standardizing workflow. METHODS: The study took place on all inpatient units at a tertiary care children's hospital between January 2020 and February 2022. Patients <22 years old with an order for an ASP-restricted medication course were included. An interprofessional team used the Model for Improvement to design interventions targeted at reducing ASP-restricted medication prescribing errors. Plan-Do-Study-Act cycles included standardizing communication and medication review, implementing protocols, and developing electronic health record safety nets. The primary outcome was the proportion of ASP-restricted medication orders with a prescribing error. The secondary outcome was time between prescribing errors. Outcomes were plotted on control charts and analyzed for special cause variation. Outcomes were monitored for a 3-month sustainability period. RESULTS: Nine-hundred ASP-restricted medication orders were included in the baseline period (January 2020-December 2020) and 1035 orders were included in the intervention period (January 2021-February 2022). The proportion of prescribing errors decreased from 10.9% to 4.6%, and special cause variation was observed in Feb 2021. Mean time between prescribing errors increased from 2.9 days to 8.5 days. These outcomes were sustained. CONCLUSIONS: Quality improvement methods can be used to achieve a sustained reduction in the proportion of ASP-restricted medication orders with a prescribing error throughout an entire children's hospital.

Evaluation of a Clinical Decision Support System and an Automated Electronic Health Record Alert on Outpatient Prescribing of Cefdinir.

Acute bacterial upper respiratory infections are common indications for antibiotics in pediatrics, and many prescriptions may be inappropriate. Novel approaches to outpatient antimicrobial stewardship interventions are needed. This quasi-experimental study of an order set and best practice advisory alert targeting cefdinir prescriptions demonstrated an 8.4% decrease in cefdinir prescribing (P ≤ .001).

Group A Streptococcus pharyngitis in Children: New Perspectives on Rapid Diagnostic Testing and Antimicrobial Stewardship.

The most common cause of bacterial pharyngitis is Group A Streptococcus (GAS). Accurate diagnosis of GAS pharyngitis is crucial to identify children who would benefit from antibiotic treatment. Rapid diagnosis has the potential to reduce antibiotic overuse. Current national guidelines differ in their recommendations for GAS testing. While rapid antigen detection tests (RADTs) are widely used, their sensitivity is considered too low for stand-alone testing by several expert bodies. Newer molecular tests using nucleic acid amplification show higher accuracy and fast results, but their cost, complexity, and very high sensitivity may limit widespread adoption. This review provides up-to-date evidence regarding rapid diagnostic testing and antimicrobial stewardship in children with sore throat. We discuss discrepancies across GAS testing guidelines at the international level, patient selection for testing for GAS, rapid test accuracy, and the potential role of rapid GAS tests to promote antibiotic stewardship, with emphasis on emerging rapid molecular tests.
