Infratriaje en urgencias de pacientes que precisan ingreso directo en cuidados intensivos por enfermedades médicas: impacto en el pronóstico y factores asociados / Undertriage of patients requiring direct admission to intensive care from the emergency department for medical conditions: impact on prognosis and associated factors

RESUMEN

Objetivo: Determinar si el infratriaje tiene impacto pronóstico en pacientes que requieren ingreso desde urgencias en cuidados intensivos por enfermedad médica e identificar factores asociados. Método: Revisión retrospectiva de pacientes atendidos durante 2018 por enfermedades médicas con ingreso directo en cuidados intensivos desde urgencias. Se clasificaron en dos grupos en función del nivel de triaje asignado y se consideró infratriaje un nivel de triaje $ III. Las variables independientes incluyeron datos demográficos, epidemiológicos e indicadores de gravedad en urgencias. Se registró la mortalidad a los 30 días (objetivo primario), así como la mortalidad hospitalaria, el ingreso prolongado en cuidados intensivos o el ingreso prolongado hospitalario (objetivos secundarios). Resultados: Se incluyeron 470 pacientes [edad 68 años (rango 57-78), 61,1% hombres] de los que 151 (32,1%) formaban el grupo con infratriaje. Los factores relacionados con el infratriaje fueron la edad (OR = 1,017; IC 95% 1,003-1,032), indicador qSOFA 0-1 (OR = 1,761; IC 95% 1,038-2,988), índice SpO2/FiO2 > 300 (OR = 2,447; IC 95% 1,418-4,223) y el diagnóstico de infección (OR = 5,003; IC 95% 2,727-9,188), respiratorio (OR = 3,993; IC 95% 1,919-8,310) u otro (OR = 1,980; IC 95% 1,036-3,785) respecto al diagnóstico cardiovascular, mientras que la admisión en horario de tarde (OR = 0,512; IC 95% 0,306-0,856) o el traslado en ambulancia (OR = 0,373; IC 95% 0,232-0,600) se relacionaron de forma inversa con el infratriaje. El evento mortalidad a 30 días tuvo lugar en 90 pacientes (19,1%). El infratriaje no se relacionó con la mortalidad a 30 días ni con el resto de los objetivos analizados. (AU)

ABSTRACT

Objectives: To determine whether undertriage affects the outcome for patients requiring direct admission to the intensive care unit (ICU) from the emergency department due to a medical condition. To identify factors associated with undertriage. Material and methods: Retrospective review of patients treated in 2018 for medical emergencies requiring direct admission to the ICU from the emergency department. The cases were classified in 2 groups according to the assigned triage level. Underestimation was defined as a triage level of III or more. Independent variables were demographic and epidemiologic data and indicators of severity recorded in the emergency department. The main outcome was 30-day mortality. Secondary outcomes were in-hospital mortality, prolonged ICU stay, and prolonged hospital stay. Results: We included 470 patients with a median age of 68 years (first-third quartile range, 57-78 years); 61.1% were men, and 151 (32.1%) were undertriaged. Factors directly related to undertriage according to odds ratios (ORs) were age (OR = 1.017; 95% CI, 1.003-1.032), Quick Sequential Organ Failure Assessment score of 0 or 1 (OR = 1.761; 95% CI, 1.038-2.988), ratio of oxygen saturation to fraction of inspired oxygen greater than 300 (OR = 2.447; 95% CI, 1.418-4.223), a diagnosis of infection (OR = 5.003, 95% CI 2.727-9.188) whether respiratory (OR = 3.993, 95% CI 1.919-8.310) or other (OR = 1.980, 95% CI, 1.036-3.785) versus a diagnosis of cardiovascular disease. Factors inversely related to undertriage were admission during the afternoon (OR = 0.512, 95% CI, 0.306-0.856) and ambulance transfer (OR = 0.373; 95% CI, 0.232-0.600). Ninety patients (19.1%) died within 30 days. Undertriage was not related to 30-day mortality or the other outcomes analyzed. (AU)
