Mortality prediction using TRISS methodology in the Spanish ICU Trauma Registry (RETRAUCI) / Predicción de la mortalidad a través de la metodología TRISS en el Registro Español de Trauma en UCI (RETRAUCI)

OBJECTIVES: To validate Trauma and Injury Severity Score (TRISS) methodology as an auditing tool in the Spanish ICU Trauma Registry (RETRAUCI). DESIGN: A prospective, multicenter registry evaluation was carried out. SETTING: Thirteen Spanish Intensive Care Units (ICUs). PATIENTS: Individuals with traumatic disease and available data admitted to the participating ICUs. INTERVENTIONS: Predicted mortality using TRISS methodology was compared with that observed in the pilot phase of the RETRAUCI from November 2012 to January 2015. Discrimination was evaluated using receiver operating characteristic (ROC) curves and the corresponding areas under the curves (AUCs) (95% CI), with calibration using the Hosmer-Lemeshow (HL) goodness-of-fit test. A value of p < 0.05 was considered significant. Main variables of interest: Predicted and observed mortality. RESULTS: A total of 1405 patients were analyzed. The observed mortality rate was 18% (253 patients), while the predicted mortality rate was 16.9%. The area under the ROC curve was 0.889 (95% CI: 0.867-0.911). Patients with blunt trauma (n=1305) had an area under the ROC curve of 0.887 (95% CI: 0.864-0.910), and those with penetrating trauma (n=100) presented an area under the curve of 0.919 (95% CI: 0.859-0.979). In the global sample, the HL test yielded a value of 25.38 (p = 0.001): 27.35 (p < 0.0001) in blunt trauma and 5.91 (p = 0.658) in penetrating trauma. TRISS methodology underestimated mortality in patients with low predicted mortality and overestimated mortality in patients with high predicted mortality. CONCLUSIONS: TRISS methodology in the evaluation of severe trauma in Spanish ICUs showed good discrimination, with inadequate calibration - particularly in blunt trauma

Objetivos: Evaluar el Trauma and Injury Severity Score (TRISS) como instrumento de auditoría en el Registro Español de Trauma en UCI. Diseño: Evaluación prospectiva de un registro multicéntrico. Ámbito: Trece UCI españolas. Pacientes: Individuos con enfermedad traumática y datos completos ingresados en las UCI participantes. Intervenciones: Comparamos la mortalidad predicha por el TRISS con la observada en la fase piloto del Registro Español de Trauma en UCI desde noviembre de 2012 hasta enero de 2015. La discriminación se evaluó mediante curvas receiver operating characteristic y el valor bajo su área (IC 95%), y la calibración, mediante el test de bondad de ajuste de Hosmer-Lemeshow. Un valor de p<0,05 se consideró significativo. Principales variables de interés: Mortalidad observada y predicha. Resultados: Analizamos 1.405 pacientes. La mortalidad observada fue del 18% (253 pacientes), mientras que la predicha fue del 16,9%. El área bajo la curva receiver operating characteristic fue de 0,889 (IC 95% 0,867-0,911). Los pacientes con trauma cerrado (n=1.305) presentaron un área bajo la curva receiver operating characteristic de 0,887 (IC 95% 0,864-0,910), y aquellos con traumatismo penetrante (n=100), de 0,919 (IC 95% 0,859-0,979). En la muestra global, el test de Hosmer-Lemeshow mostró un valor de 25,38 (p=0,001), siendo de 27,35 (p<0,0001) en trauma cerrado y de 5,91 (p=0,658) en trauma penetrante. La metodología TRISS infraestimó la mortalidad en los pacientes con mortalidad predicha baja y la sobreestimó en pacientes con mortalidad predicha elevada. Conclusiones: La aplicación de la metodología TRISS en el trauma grave ingresado en las UCI españolas mostró buenos niveles de discriminación y una calibración inadecuada, especialmente en el traumatismo cerrado (AU)

Predicción de la utilidad clínica de la radiografía de tórax rutinaria en una unidad de cuidados intensivos de traumatología / Prediction of the clinical usefulness of routine chest X-rays in a traumatology ICU

IntroducciónEl valor de la radiografía torácica rutinaria está en cuestión. Sin embargo, este asunto no ha sido suficientemente evaluado en el caso concreto del paciente traumatizado. Nos propusimos encontrar predictores de utilidad en este entorno.Material y métodosEstudio observacional prospectivo en una UCI de traumatología de 8 camas. Se incluyeron los pacientes de más de 15 años, con traumatismo grave (ISS > 15), ingresados 48h o más. Se excluyeron las mujeres embarazadas y las radiografías no rutinarias. Un miembro del equipo médico examinó de manera independiente las placas, en busca de hallazgos radiográficos según se definían en una lista cerrada. Durante la ronda diaria, los médicos al cargo comunicaron cuantos cambios en el estado clínico y en el manejo ocurrieron tras la toma de la radiografía, también siguiendo una lista de criterios cerrados. La relación entre ambas variables se estudió por análisis univariante y multivariante.ResultadosDurante un año se obtuvieron 1.440 radiografías de 138 pacientes consecutivos. Predominaron los varones (82%), de edad joven (39±1 años). El 97% sufrieron traumatismo contuso; el 52%, traumatismo torácico grave. La estancia media se prolongó 12,9±10,1 días. En el 86,8% se empleó ventilación mecánica. De cada paciente se realizaron 10,4±9,3 placas. En el 14% hubo hallazgos relevantes, con mayor frecuencia una malposición de un dispositivo (6,8%) o infiltrados (4,9%), desencadenando una acción clínica en el (..) (AU)

BACKGROUND: The clinical value of routine chest X-rays in critical care has been questioned, but has not been studied in the trauma environment to date. The objective of this study was to identify easy to use clinical predictors of utility in this setting. MATERIAL AND METHODS: A prospective observational study was made in an 8-bed traumatology ICU. Severe trauma patients (ISS > 15), aged 15 or older and admitted for 48 h or longer were included. Pregnant women and radiographs obtained during initial care or for reasons other than routine indication were excluded. A staff physician, separated from clinical duties, independently reviewed the films in search of changes, as described in a closed checklist. Following closed criteria, the attending physicians reported previous day clinical events and changes in clinical management after chest X-ray obtainment. Demographic and epidemiological data were also recorded. The associations among variables were studied by univariate and multivariate analysis. RESULTS: A total of 1440 routine chest X-rays were obtained from 138 consecutive patients during one year. Young males prevailed (82%; 39 ± 16 years). The most common process was severe blunt trauma (97%). Fifty-two percent suffered severe chest trauma. The mean length of stay was 12.9 ± 10.1 days. Mechanical ventilation was used in 86.8% of the cases. A median of 10.4 ± 9.3 films were obtained from each patient. A total of 14% of the X-rays showed changes, most commonly malpositioning of an indwelling device (6.8%) or infiltrates (4.9%). Those findings led to a change in care in 84.6% of the cases. Multivariate analysis identified the following significant (p < 0.05) risk factors for radiographic changes: first two days of evolution, mechanical ventilation, worsening of PaO2/FiO2, worsening of lung compliance and changes in respiratory secretions. CONCLUSIONS: Based on the results obtained, the risk of not identifying dangerous conditions by restricting routine chest X-rays prescription to the described conditions is low. Observing this policy would probably mean substantial savings and a reduction in radiation exposure.

[Diagnostic and therapeutic alternatives in perioperative acute myocardial ischemia in heart surgery]. / Diagnóstico y alternativas terapéuticas en la isquemia miocárdica aguda perioperatoria en cirugía coronaria.

Ischemia and infarct after surgical revascularization are a relatively frequent complication, with high morbidity and mortality. Early diagnosis is essential. However, this is less standardized and more complicated to diagnose than in patients who have not undergone surgery since there is no specific biomarker that allows the clinician to differentiate between myocardial ischemia due to the procedure itself and myocardial damage due to perioperative infarct. Once detected, perioperative ischemia should be treated immediately in order to limit myocardial damage. The objectives of this study have been 1. To show the diagnostic criteria for perioperative infarct and ischemia. 2. to show the different therapeutic options available. 3. to propose a treatment algorithm that includes the differential diagnosis, how to control vasospasm, implantation of balloon counterpulsation, and the possible revascularization strategies (percutaneous coronary intervention vs reoperation).
