Una evaluación preoperatoria adecuada reduce costos, la tasa de suspensión de cirugías y días de hospitalización. Este estudio mide la variación interobservador de la clasificación del estado físico de la Sociedad Americana de Anestesiología entre especialidades en la valoración preoperatoria, buscando optimizar la protocolización del paciente quirúrgico.  Material y métodos:  se realizó un estudio descriptivo, observacional y transversal en el Hospital Ángeles Clínica Londres, aplicando un cuestionario con 12 casos clínicos hipotéticos para identificar diferencias en el conocimiento y uso de dicha clasificación.  Resultados:  se evaluaron 80 especialistas; 46.9% reconoció que la clasificación valora el estado físico de los pacientes, 67.9% desconoce la última modificación de la clasificación y 79% solicita estudios adicionales según el puntaje que le asignan al estado físico del paciente. Los anestesiólogos tienden a clasificar con mayor uniformidad, comparado con otras especialidades que muestran mayor variabilidad al clasificar, lo que puede generar inconsistencias en la valoración.  Conclusión:  este estudio resalta la necesidad de una mejor estandarización en el uso de la clasificación del estado físico de la Sociedad Americana de Anestesiología entre especialidades médicas para garantizar una valoración más uniforme del riesgo preoperatorio.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Introduction:  the American Society of Anesthesiologists physical status classification system is a widely used method for risk stratification by the surgical team; however, many clinicians misuse it. Proper preoperative assessment reduces costs, surgery cancellation rates, and hospital stays. This study evaluates interobserver variation in the American Society of Anesthesiologists physical status assignment across specialties during preoperative assessment, aiming to optimize surgical patient protocol.  Material and methods:  a descriptive, observational, and cross-sectional study was conducted at Hospital Angeles Clinica Londres. A questionnaire with 12 hypothetical clinical cases was administered to identify differences in knowledge and usage of the American Society of Anesthesiologists physical status classification system.  Results:  eighty specialists were evaluated; 46.9% recognized that the classification assesses patients&#8217; physical status, 67.9% were unaware of the latest classification modification, and 79% requested additional tests based on their physical status assignment. Anesthesiologists tended to classify patients more consistently compared to other specialties, which exhibited greater variability in their classifications, potentially leading to inconsistencies.  Conclusion:  this study highlights the need for better standardization in the use of the American Society of Anesthesiologists physical status classification system across medical specialties to ensure more uniform assessment of preoperative risk.]]></p></abstract>
