Intervención educativa para mejorar la prescripción de ceftriaxona en un servicio de urgencias / Educational intervention to improve ceftriaxone prescription in an emergency department

Objetivo: Evaluar prevalencia y adecuación de ceftriaxona tras una intervención educativa en un servicio de urgencias.Métodos: Estudio cuasi experimental que incluyó un mues-treo consecutivo de consultas no programadas de pacien-tes adultos, durante dos meses preintervención y posin-tervención. Dicha intervención consistió en capacitación a médicos para limitar su indicación sólo a situaciones clínicas específicas (meningitis, enfermedad pélvica infla-matoria y abdomen agudo). Se utilizaron datos retrospecti-vos, con adicional revisión manual de historias, para validar adecuación de inicio antibiótico y apropiabilidad de droga. Se utilizó estadística descriptiva y analítica.Resultados: De un total de 28.570 consultas, 512 recibie-ron ceftriaxona (1,79%; IC95% 1,64-1,95), y sólo 60,54% se hospitalizaron. En cuanto a la comparación antes-después, se observó una reducción en la tasa de uso (de 3,66% a 0,63%; p<0,001), la adecuación en el inicio de un antimicro-biano se mantuvo (de 84,52% a 86,21%; p=0,778), aunque la adecuación de ceftriaxona aumentó en forma significativa (de 41,78% a 84,00% respectivamente; p<0,001). Adicional-mente, se redujo el tiempo de estadía hospitalaria (media-na de 6 a 5 días; p=0,014), sin diferencias en la mortalidad intrahospitalaria (19,44% vs 17,24%; p=0,691), ni en la mor-talidad a los 30 días (23,41% vs 18,96%; p=0,464).Conclusiones: Esta intervención resultó eficaz. Los hallaz-gos representan un paso fundamental en los programas de optimización del uso de antimicrobianos hospitalarios, que apuntan a reducir su sobreutilización y la consecuente resistencia.

Objective: To evaluate the prevalence and appropriateness of ceftriaxone after an educational intervention in an emergency department.Methods: Quasi-experimental study, which included a consecutive sampling of unscheduled consultations of adult patients, during 2 months pre-intervention and post-intervention. The intervention consisted of training physicians to limit its indication only to specific clinical situations (meningitis, pelvic inflammatory disease, and acute abdomen). Retrospective data were used, with additional manual chart review, to validate appropriateness of antibiotic initiation and drug appropriateness. Descriptive and analytical statistics were used.Results: Among 28570 visits, 512 received ceftriaxone (1.79%; 95%CI 1.64-1.95), and only 60.54% were hospitalized. Regarding the before-after comparison, we observed a reduction in the rate of use (from 3.66% to 0.63%; p<0.001), the appropriateness in starting an antimicrobial was maintained (from 84.52% to 86.21%; p=0.778), and the appropriateness of ceftriaxone increased significantly (from 41.78% to 84.00% respectively; p<0.001). Additionally, hospital length of stay was reduced (median 6 to 5 days; p=0.014), with no difference in in-hospital mortality (19.44% vs 17.24%; p=0.691), nor in 30-day mortality (23.41% vs 18.96%; p=0.464)

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
