    El número de pacientes que busca atención en el servicio de urgencia ha ido aumentando progresivamente. Este fenómeno, sumado a la falta de camas disponibles dentro del hospital, determina que se produzca un desbalance entre la oferta y demanda de atenciones médicas. Así, los pacientes compiten por los recursos disponibles en determinado momento. La evaluación de riesgo o triage en un servicio de urgencia permite determinar la gravedad o necesidad de atención médica inmediata de los pacientes de manera estructurada. Establece prioridades y asigna a los pacientes a sectores y tiempos de atención apropiados para el cuadro que los aqueja. En la actualidad, los métodos de triage más ampliamente usados por su validez y reproducibilidad son the australasian triage scale, the Canadian triage and acuity scale, the Manchester triage system y the emergency severity index, los cuales clasifican a los pacientes en cinco categorías de riesgo. En los servicios de urgencia públicos chilenos, se está empleando un sistema de categorización de riesgo de cinco niveles (C1 a C5) basado principalmente en la experiencia clínica del enfermero(a) del triage.

    Point-of-Care Ultrasound stratified by the Wells Score for the diagnosis of proximal deep vein thrombosis: A Prospective Study
    (2025) Rojas Muñoz, Nicolás; Clausdorff Fiedler, Hans Jurgen; Riquelme Morales, Felipe Ignacio; Vidal Zamorano, Victor Alejandro; Seydewitz Osses, María Francisca; Rivera Gonzalez, Sofía Viviana; Basaure Verdejo, Carlos Eugenio
    Background Deep vein thrombosis (DVT) affects 1 in 1000 people, with complications associated both in under and over diagnosis. Duplex ultrasound is the gold standard but its use in emergency settings is limited. Two-point Point-of-Care ultrasound protocol performed by emergency physicians can foster its diagnosis. However, 6 % of cases can be missed and its performance stratified by clinical pre-test probability is unknown. Objective To evaluate the diagnostic performance of an extended compression ultrasound (ECUS) protocol performed by emergency physicians when stratified by Wells score. Methods We conducted a prospective diagnostic accuracy study. Adult patients (≥18 years) with suspected DVT were stratified by Wells score (low, intermediate, high risk) and underwent ECUS by trained emergency physicians or residents. Results were compared to complete duplex ultrasound (CDUS) performed by radiologists within 24 h. Results Among 194 patients analyzed (54 % female, mean age 61 ± 18 years), the overall prevalence of proximal DVT was 17 %. The ECUS protocol demonstrated a global sensitivity of 97 % (95 % CI: 84.2–99.9), specificity of 94.4 % (95 % CI: 89.7–97.4), positive predictive value of 78.6 % (95 % CI: 63.2–89.4), and negative predictive value of 99.3 % (95 % CI: 96.4–100). In the low-risk group, sensitivity was 100 % (95 % CI: 29.2–100) with a negative predictive value of 100 % (95 % CI: 90.7–100). Conclusion The combined use of Wells score stratification and ECUS can reliably exclude proximal DVT in low and intermediate-risk patients, potentially optimizing emergency department resources and facilitating timely clinical decisions. In low-risk patients, this strategy may yield results comparable to comprehensive Doppler ultrasound.
