Effectiveness and predictors of failure of noninvasive mechanical ventilation in acute respiratory failure.

OBJECTIVE: To assess the effectiveness and identify predictors of failure of noninvasive ventilation. DESIGN: A retrospective, longitudinal descriptive study was made. SETTING: Adult patients with acute respiratory failure. PATIENTS: A total of 410 consecutive patients with noninvasive ventilation treated in an Intensive Care Unit of a tertiary university hospital from 2006 to 2011. PROCEDURES: Noninvasive ventilation. MAIN VARIABLES OF INTEREST: Demographic variables and clinical and laboratory test parameters at the start and two hours after the start of noninvasive ventilation. Evolution during admission to the Unit and until hospital discharge. RESULTS: The failure rate was 50%, with an overall mortality rate of 33%. A total of 156 patients had hypoxemic respiratory failure, 87 postextubation respiratory failure, 78 exacerbation of chronic obstructive pulmonary disease, 61 hypercapnic respiratory failure without chronic obstructive pulmonary disease, and 28 had acute pulmonary edema. The failure rates were 74%, 54%, 27%, 31% and 21%, respectively. The etiology of respiratory failure, serum bilirubin at the start, APACHEII score, radiological findings, the need for sedation to tolerate noninvasive ventilation, changes in level of consciousness, PaO2/FIO2 ratio, respiratory rate and heart rate from the start and two hours after the start of noninvasive ventilation were independently associated to failure. CONCLUSIONS: The effectiveness of noninvasive ventilation varies according to the etiology of respiratory failure. Its use in hypoxemic respiratory failure and postextubation respiratory failure should be assessed individually. Predictors of failure could be useful to prevent delayed intubation.

Mortality prediction using TRISS methodology in the Spanish ICU Trauma Registry (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.

Epidemiology of severe trauma in Spain. Registry of trauma in the ICU (RETRAUCI). Pilot phase. / Epidemiología del trauma grave en España. REgistro de TRAuma en UCI (RETRAUCI). Fase piloto.

OBJECTIVE: To describe the characteristics and management of severe trauma disease in Spanish Intensive Care Units (ICUs). Registry of trauma in the ICU (RETRAUCI). Pilot phase. DESIGN: A prospective, multicenter registry. SETTING: Thirteen Spanish ICUs. PATIENTS: Patients with trauma disease admitted to the ICU. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Epidemiology, out-of-hospital attention, registry of injuries, resources utilization, complications and outcome were evaluated. RESULTS: Patients, n=2242. Mean age 47.1±19.02 years. Males 79%. Blunt trauma 93.9%. Injury Severity Score 22.2±12.1, Revised Trauma Score 6.7±1.6. Non-intentional in 84.4% of the cases. The most common causes of trauma were traffic accidents followed by pedestrian and high-energy falls. Up to 12.4% were taking antiplatelet medication or anticoagulants. Almost 28% had a suspected or confirmed toxic influence in trauma. Up to 31.5% required an out-of-hospital artificial airway. The time from trauma to ICU admission was 4.7±5.3hours. At ICU admission, 68.5% were hemodynamically stable. Brain and chest injuries predominated. A large number of complications were documented. Mechanical ventilation was used in 69.5% of the patients (mean 8.2±9.9 days), of which 24.9% finally required a tracheostomy. The median duration of stay in the ICU and in hospital was 5 (range 3-13) and 9 (5-19) days, respectively. The ICU mortality rate was 12.3%, while the in-hospital mortality rate was 16.0%. CONCLUSIONS: The pilot phase of the RETRAUCI offers a first impression of the epidemiology and management of trauma disease in Spanish ICUs.

Prognostic factors associated with mortality in patients with severe trauma: from prehospital care to the Intensive Care Unit.

OBJECTIVE: To identify factors related to mortality in adult trauma patients, analyzing the clinical, epidemiological and therapeutic characteristics at the pre-hospital levels, in the Emergency Care Department and in Intensive Care. DESIGN: A retrospective, longitudinal descriptive study was carried out. Statistical analysis was performed using SPSS, MultBiplot and data mining methodology. SETTING: Adult multiple trauma patients admitted to the Salamanca Hospital Complex (Spain) from 2006 to 2011. MAIN VARIABLES OF INTEREST: Demographic variables, clinical, therapeutic and analytical data from the injury site to ICU admission. Evolution from ICU admission to hospital discharge. RESULTS: A total of 497 patients with a median age of 45.5 years were included. Males predominated (76.7%). The main causes of injury were traffic accidents (56.1%), precipitation (18.4%) and falls (11%). The factors with the strongest association to increased mortality risk (P<.05) were age > 65 years (OR 3.15), head injuries (OR 3.1), pupillary abnormalities (OR 113.88), level of consciousness according to the Glasgow Coma Scale ≤ 8 (OR 12.97), and serum lactate levels > 4 mmol/L (OR 9.7). CONCLUSIONS: The main risk factors identified in relation to the prognosis of trauma patients are referred to the presence of head injuries. Less widely known statistical techniques such as data mining or MultBiplot also underscore the importance of other factors such as lactate concentration. Trauma registries help assess the healthcare provided, with a view to adopting measures for improvement.

[Prognostic factors in severe traumatic brain injury]. / Factores pronósticos del traumatismo craneoencefálico grave.

OBJECTIVE: To describe the factors associated to mortality of patients with severe traumatic brain injury (TBI). DESIGN: A retrospective observational study was made of patients with severe TBI covering the period between 1 January 2007 and 31 December 2010. SETTING: Virgen de la Vega Hospital, Salamanca (Spain). PATIENTS: All patients hospitalized during the consecutive study period. MAIN VARIABLES OF INTEREST: The dependent variable has been the death rate, while the independent variables were divided into two groups: epidemiological and clinical. RESULTS: The mean patient age was the 50.84 years; 75.5% were males. The average score on the Glasgow Coma Scale (GCS) was 5.09, and the average Injury Severity Score (ISS) was 30.8. Higher mortality was observed in older patients with a higher ISS score. A total of 68.1% of the patients in which intracranial pressure (ICP) was monitored showed intracranial hypertension (ICH). The mortality rate in patients with severe TBI was 36.8%, and was associated mainly to a lower GCS score, the existence of hyperglycemia, coagulopathy, hypoxemia, the presence of mydriasis and shock. The independent mortality indicators in patients with severe TBI were the existence of mydriasis (OR: 32.75), the GCS score (OR: 2.65) and hyperglycemia (OR: 6.08). CONCLUSIONS: The existence of mydriasis, the GCS score and hyperglycemia should be taken into account as prognostic factors in TBI patients.

Scoring severity in trauma: comparison of prehospital scoring systems in trauma ICU patients.

PURPOSE: We evaluated the predictive ability of mechanism, Glasgow coma scale, age and arterial pressure (MGAP), Glasgow coma scale, age and systolic blood pressure (GAP), and triage-revised trauma Score (T-RTS) scores in patients from the Spanish trauma ICU registry using the trauma and injury severity score (TRISS) as a reference standard. METHODS: Patients admitted for traumatic disease in the participating ICU were included. Quantitative data were reported as median [interquartile range (IQR), categorical data as number (percentage)]. Comparisons between groups with quantitative variables and categorical variables were performed using Student's T Test and Chi Square Test, respectively. We performed receiving operating curves (ROC) and evaluated the area under the curve (AUC) with its 95 % confidence interval (CI). Sensitivity, specificity, positive predictive and negative predictive values and accuracy were evaluated in all the scores. A value of p < 0.05 was considered significant. RESULTS: The final sample included 1361 trauma ICU patients. Median age was 45 (30-61) years. 1092 patients (80.3 %) were male. Median ISS was 18 (13-26) and median T-RTS was 11 (10-12). Median GAP was 20 (15-22) and median MGAP 24 (20-27). Observed mortality was 17.7 % whilst predicted mortality using TRISS was 16.9 %. The AUC in the scores evaluated was: TRISS 0.897 (95 % CI 0.876-0.918), MGAP 0.860 (95 % CI 0.835-0.886), GAP 0.849 (95 % CI 0.823-0.876) and T-RTS 0.796 (95 % CI 0.762-0.830). CONCLUSIONS: Both MGAP and GAP scores performed better than the T-RTS in the prediction of hospital mortality in Spanish trauma ICU patients. Since these are easy-to-perform scores, they should be incorporated in clinical practice as a triaging tool.

PACIENTES: Un total de 410 pacientes (muestra consecutiva) tratados mediante ventilación mecánica no invasiva en una unidad de cuidados intensivos de un hospital universitario terciario entre 2006 y 2011. INTERVENCIONES: Ventilación mecánica no invasiva. VARIABLES PRINCIPALES DE INTERÉS: Variables demográficas, clínicas y analíticas desde el inicio de la ventilación mecánica no invasiva y 2h después. Variables evolutivas durante el ingreso en la unidad y hasta el alta hospitalaria. RESULTADOS: El fracaso fue del 50%, y la mortalidad global del 33%. Un total de 156 pacientes presentaban insuficiencia respiratoria aguda hipoxémica, 87 insuficiencia respiratoria postextubación, 78 reagudización de enfermedad pulmonar obstructiva crónica, 61 insuficiencia respiratoria hipercápnica sin enfermedad pulmonar obstructiva crónica y 28 edema pulmonar agudo cardiogénico. El fracaso fue del 74, del 54, del 27, del 31 y del 21%, respectivamente. El tipo de insuficiencia respiratoria, la bilirrubina sérica al inicio, APACHEII, la existencia de hallazgos radiológicos, la necesidad de sedación para tolerarla y los cambios en el nivel de consciencia, ratio PaO2/FiO2, frecuencia respiratoria y frecuencia cardiaca entre el inicio y 2 h después se asociaron con el fracaso. CONCLUSIONES: La efectividad de la técnica varió dependiendo del tipo de insuficiencia respiratoria. Su uso en la insuficiencia respiratoria aguda hipoxémica y la insuficiencia respiratoria postextubación debería valorarse individualmente. Los predictores de fracaso podrían ser útiles para prevenir el retraso en la intubación orotraqueal

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)

DISEÑO: Estudio observacional retrospectivo de los pacientes con TCEG en el periodo comprendido entre el 1 de enero de 2007 y el 31 de diciembre de 2010. Ámbito: Hospital Virgen de la Vega de Salamanca. PACIENTES: Los 106 pacientes con TCEG ingresados de forma consecutiva en el periodo de estudio. Variables de interés: La variable dependiente ha sido la mortalidad y las distintas variables independientes han sido divididas en 2 grupos: epidemiológicas y clínicas. RESULTADOS: La edad media fue de 50,84 años. El 75,5% de los casos eran varones. La puntuación media en la escala de Glasgow (GCS) fue de 5,09 y el Injury Severity Score (ISS) medio fue de 30,8. Se observa mayor mortalidad en los pacientes con edad más avanzada y puntuación ISS más alta. Un 68,1% de los pacientes en los que se monitorizó la presión intracraneal (PIC) presentaron hipertensión intracraneal (HIC). La mortalidad de los pacientes con TCEG fue del 36,8% y se asoció de forma significativa a una menor puntuación del GCS, a la existencia de hiperglucemia, HIC, coagulopatía, hipoxemia, presencia de midriasis y shock. Los factores responsables de la mortalidad de forma independiente en los pacientes con TCEG fueron la existencia de midriasis (OR: 32,75), puntuación del GCS (OR: 2,65) e hiperglucemia (OR: 6,08). CONCLUSIONES: La existencia de midriasis, la puntuación del GCS y la hiperglucemia deben ser tenidas en cuenta como factores pronóstico del TCEG
