RESUMO
BACKGROUND: Brain death is defined as the irreversible loss of all functions of the brain, including the brainstem. The objective is to know the attitude and knowledge toward brain death of the medical personnel involved in the process of the organ/tissue transplantation and donation in a third level hospital of Mexico City. METHODS: 67 attending physicians were interviewed with the methodology of pen, paper and a printed questionnaire. They were distributed in two groups: group A, consisting of non-surgical physicians, and group B, which was formed by surgical physicians. It was analyzed the attitude and knowledge of the criteria established in the Ley General de Salud (General Law of Health) of Mexico. Thirty-five men and 32 women (median age 42 years) responded to the survey. RESULTS: More than 90 % of both groups would wish to participate in a brain death course, and they would accept to be potential donors or receptors of transplanted organs. A high percentage knows partially the law on brain death (Ley General de Salud) and clinical procedures. Of the interviewed population, 68 % does not know the standard complementary studies to confirm the diagnosis of brain death. Non-significant differences were observed in the attitude and knowledge of both groups (p = 0.170). CONCLUSION: Physicians must improve their knowledge on brain death.
Introducción: la muerte encefálica se define como el cese irreversible de las funciones de las estructuras neurológicas intracraneales, tanto de los hemisferios cerebrales como del troncoencéfalo. El objetivo es conocer la actitud y los conocimientos que tiene ante la muerte encefálica el personal médico relacionado con el trasplante y la donación de órganos y tejidos en un hospital de tercer nivel de la ciudad de México. Métodos: fueron encuestados 67 médicos con el método de pluma, papel y un cuestionario impreso; se distribuyeron en dos grupos: grupo A no quirúrgicos y grupo B quirúrgicos. Se exploraron la actitud y los conocimientos de los criterios establecidos en la Ley General de Salud en México. Contestaron la encuesta 35 hombres y 32 mujeres, con una mediana de edad de 42 años. Resultados: más del 90 % en ambos grupos desearía participar en un curso-taller de muerte encefálica, así como ser potenciales donadores y receptores de órganos. Un alto porcentaje conoce parcialmente la ley sobre muerte encefálica y los conceptos clínicos. El 68 % de la población encuestada no conoce los estudios complementarios establecidos para confirmar el diagnóstico de muerte encefálica. Al comparar ambos grupos no se encontró diferencia significativa (p = 0.170). Conclusión: el médico debe responsabilizarse más en el dominio de la muerte encefálica.

CONTEXT: The performance of a prognostic score must be evaluated prior to being used. The aim of the present study was to evaluate the predictive ability of hospital mortality of Simplified Acute Physiology Score 3 (SAPS 3) score in elderly patients admitted to Intensive Care Units (ICUs). AIMS: The aim of the present study was to evaluate the SAPS 3 score predictive ability of hospital mortality in elderly patients admitted to ICU. SETTINGS AND DESIGN: This study was conducted as a prospective cohort, in two mixed ICUs. PATIENTS AND METHODS: Two hundred and eleven elderly patients were included. INTERVENTIONS: None. We compared the predictive accuracy of SAPS 3 measured at the first hour at ICU and Acute Physiology and Chronic Health Evaluation II (APACHE II) measured with the worst values in the first 24 h at ICU. The patients were followed until hospital discharge. STATISTICAL ANALYSIS USED: Evaluation of discrimination through area under curve receiver operating characteristic (aROC) and calibration by Hosmer-Lemeshow (HL) test. RESULTS: The median age was 68 years. The hospital mortality rate was 35.54%. The mean value of SAPS 3 was 62.54 ± 12.51 and APACHE II was 17.46 ± 6.77. The mortality predicted by APACHE II was 24.98 ± 19.96 and for standard SAPS 3 equation 41.18 ± 22.34. The discrimination for SAPS 3 model was aROC = 0.68 (0.62-0.75) and to APACHE II aROC = 0.70 (0.63-0.78). Calibration: APACHE II with HL 10.127 P = 0.26, and standard SAPS 3 equation HL 7.204 P = 0.51. CONCLUSIONS: In this study, the prognostic model of SAPS 3 was not found to be accurate in predicting mortality in geriatric patients requiring ICU admission.
