Peer Review Process

Manuscripts submitted to Memorias del Instituto de Investigaciones en Ciencias de la Salud undergo a double-blind peer review process, in which the identities of both authors and reviewers remain anonymous throughout the evaluation. Each manuscript is assessed by a minimum of two external reviewers with expertise in the relevant subject area, who are given a period of 30 days to submit their evaluation. Reviewers assess the originality, methodological rigor, scientific relevance, and clarity of presentation of each work. Based on the reviewers' reports, the Editorial Committee decides whether to accept, request revisions, or reject the manuscript, and communicates the decision to the authors as promptly as possible. This process ensures impartiality, transparency, and the scientific quality of published articles.

Abstract

El objetivo de este estudio descriptivo, retrospectivo y transversal fue determinar la sensibilidad a los antimicrobianos de las enterobacterias obtenidas de los cultivos de orina en el Hospital Central del Instituto de Previsión Social (IPS) y comparar la tasa de sensibilidad según la especie y el origen de la muestra. Se realizó la revisión retrospectiva del expediente clínico de pacientes ambulatorios y hospitalizados diagnosticados como infección urinaria que ingresaron en el Hospital Central del IPS entre marzo del 2015 y agosto del 2016. Se incluyeron 4014 aislamientos de enterobacterias de infecciones urinarias, 3224 (80,3%) fueron muestras ambulatorias y 790 (19,7%) de pacientes hospitalizados. El patógeno urinario más frecuente fue Escherichia coli (70,1%) seguido de Klebsiella pneumoniae (18,9%), Enterobacter cloacae (2,8%) y otras especies (8,2%). La sensibilidad de E. coli a fosfomicina, nitrofurantoína y aminoglucósidos fue alta. El 24,4% de E. coli y el 50,3% de K. pneumoniae fueron productores de betalactamasa de espectro extendido (BLEE). E. coli sigue siendo la causa más frecuente de infecciones del tracto urinario. El tratamiento de elección recomendado es fosfomicina, nitrofurantoína o aminoglucósidos, ya que este esquema cubrirá más del 90% de los patógenos que causan infección del tracto urinario en el hospital de IPS. Deben investigarse las enterobacterias que producen infección urinaria atípica.
