Empirical and post-susceptibility antimicrobial regimens were assessed according to the Sanford Guide and VNACCEMT 2020 recommendations.<\/p>\r\n<p style=\"text-align: justify;\"><em>Results<\/em>: Respiratory infection was the most frequent source of sepsis. Cultures were performed in 63 patients, and blood cultures were positive in 32. The main pathogens were <em>Klebsiella pneumoniae<\/em> (38.1%), <em>Acinetobacter baumannii<\/em> (22.2%), <em>Pseudomonas<\/em> <em>aeruginosa<\/em> (14.3%), and methicillin-resistant <em>Staphylococcus aureus<\/em> (11.1%). Levofloxacin and piperacillin-tazobactam were commonly prescribed empirically, whereas meropenem, linezolid, and colistin were frequently used after susceptibility results. Empirical adherence to Sanford Guide and VNACCEMT recommendations was 32.1% and 56.6%, respectively. Post-susceptibility adherence was 46.4% and 50.0%, respectively. Adherence to the Sanford Guide after susceptibility testing was associated with treatment success at discharge, defined as recovery or improvement (OR 2.301, 95% CI 1.105\u20134.792; p = 0.026). The in-hospital mortality rate was 41.5%.<\/p>\r\n<p style=\"text-align: justify;\"><em>Conclusions<\/em>: Inappropriate empirical antimicrobial therapy was frequent in this high-resistance ICU cohort. Adherence to antimicrobial stewardship recommendations, particularly Sanford Guide-based adjustments after susceptibility results became available, was associated with improved discharge outcomes in the exploratory multivariable analysis. Locally adapted empirical therapy combined with PK\/PD-optimized targeted dosing should be evaluated prospectively.<\/p>\r\n<p style=\"text-align: justify;\"><em>Keywords<\/em>: antimicrobial stewardship; antimicrobial susceptibility testing; critical care; drug resistance, bacterial; drug resistance, multiple, bacterial; treatment outcome.<\/p>\r\n<!-- \/wp:paragraph -->\r\n\r\n&nbsp;\r\n\r\n<!-- wp:image {\"linkDestination\":\"custom\"} -->\r\n<figure class=\"wp-block-image\"><a href=\"https:\/\/jppres.com\/jppres\/pdf\/vol14\/jppres_14.3.2799.pdf\" target=\"_blank\" rel=\"noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"PDF Download\" src=\"https:\/\/jppres.com\/jppres\/wp-content\/uploads\/2013\/09\/jppres_pdf_free.png\" alt=\"PDF Download\" width=\"40\" height=\"20\" \/><\/a><\/figure>\r\n<!-- \/wp:image -->\r\n\r\n&nbsp;\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4 id=\"block-98722437-95d1-45d3-a5f6-d46d54bbb00e\" class=\"wp-block-heading\">Resumen<\/h4>\r\n<!-- \/wp:heading --><!-- wp:paragraph -->\r\n<p style=\"text-align: justify;\"><em>Contexto<\/em>: La sepsis sigue siendo una causa importante de mortalidad en las unidades de cuidados intensivos, y la selecci\u00f3n de antimicrobianos se ve complicada por los patrones locales de resistencia.<\/p>\r\n<p style=\"text-align: justify;\"><em>Objetivos<\/em>: Describir el uso de antimicrobianos y evaluar la asociaci\u00f3n entre la adherencia a las gu\u00edas y los desenlaces al alta en pacientes adultos con sepsis o shock s\u00e9ptico en la UCI.<\/p>\r\n<p style=\"text-align: justify;\"><em>M\u00e9todos:<\/em> Se llev\u00f3 a cabo un estudio de cohorte observacional retrospectivo con 106 historias cl\u00ednicas de pacientes adultos ingresados en la UCI del Hospital Dong Nai 2 entre enero de 2023 y febrero de 2024. Los reg\u00edmenes antimicrobianos emp\u00edricos y posteriores al antibiograma se evaluaron seg\u00fan las recomendaciones de la Sanford Guide y de las gu\u00edas de la VNACCEMT 2020.<\/p>\r\n<p style=\"text-align: justify;\"><em>Resultados<\/em>: La infecci\u00f3n respiratoria fue la fuente m\u00e1s frecuente de sepsis.

La adherencia emp\u00edrica a las recomendaciones de la Sanford Guide y de VNACCEMT fue del 32,1% y del 56,6%, respectivamente. La adherencia posterior al antibiograma fue del 46,4% y del 50,0%, respectivamente. La adherencia a la Sanford Guide tras las pruebas de sensibilidad se asoci\u00f3 con el \u00e9xito terap\u00e9utico al alta, definido como recuperaci\u00f3n o mejor\u00eda (OR 2,301; IC 95% 1,105\u20134,792; p = 0,026).

La adherencia a las recomendaciones del programa de uso racional de antimicrobianos, en particular los ajustes basados en la Gu\u00eda Sanford tras la disponibilidad de los resultados de susceptibilidad, se asoci\u00f3 con mejores desenlaces al alta en el an\u00e1lisis multivariable exploratorio.
