Construcción y validación de la escala EsVida para la valoración del requerimiento de manejo en urgencias de una gastroenteritis infecciosa

Introduction: Infectious gastroenteritis can result in unnecessary emergency room consultations. Instruments are needed to detect the risks for unfavorable progression. Aim: To develop and validate a comprehensive severity scale for acute gastroenteritis in children. Materials and methods: Data associated with complications (probable items) were determined through a MeSH search. The EsVida scale was developed with 4 theoretic domains: personal history (3 items), social problems (2 items), risks for severe gastroenteritis (4 items), and signs of fluid and electrolyte imbalance (4 items). The items were evaluated as present (one point) or absent (zero points) on a 0 to 13-point scale. To validate the instrument, an observational study was conducted at the emergency service on children from one to 13 years of age with acute gastroenteritis. The scale was re-developed utilizing the risks calculated by logistic regression analysis. © Revista de Gastroenterología de México
