Limitación de tratamiento de soporte vital en una Unidad de Cuidado Intensivo pediátrica chilena: 2004-2014 / Limitation of Vital Support in a Chilean Pediatric Intensive Care Unit: 2004-2014

Resumen Objetivo: Describir las frecuencias y características del proceso de Limitación de Tratamiento de So porte Vital (LTSV) en pacientes de la Unidad de Cuidados Intensivos Pediátricos (UCI) entre 2004 2014. Pacientes y Método: Estudio retrospectivo, observacional descriptivo a partir de dos registros de la UCI del Hospital Roberto del Río: 1) ficha clínica individual de seguimiento y 2) ficha de registro de indicadores de calidad incluida LTSV, ambos actualizados diariamente al iniciar la visita clínica. Desde estos registros se analizaron los casos con dilemas bioéticos en los que se propuso LTSV du rante su hospitalización en UCI ("LTSV intra-UCI"). Se menciona la población rechazada de ingresar a UCI ("LTSV pre-UCI") y los fallecidos con LTSV en cama básica. Resultados: De 7.821 ingresos a UCI en el 1,51% (118 pacientes) se establece una LTSV: ONI (Orden de No Innovación) en 78,8% de los casos, retiro de medidas terapéuticas en 14,4% y suspensión de ventilación mecánica en 6,8%. En 23,7% el diagnóstico de base fue neurológico u oncológico, para cada uno. La condición fisiopatológica predominante para una LTSV fue neurológica (39%). El tiempo de estadía en UCI triplica el promedio de estada de los egresos totales de UCI, pero es de amplia variabilidad. Conclusiones: Es factible realizar una LTSV en UCI cuando el equipo incorpora esta perspectiva al trabajo diario junto a la familia. Hay una amplia variabilidad individual en las características del proceso de LTSV, propio del ámbito de la ética clínica.

Abstract Objective: Describe the frequency and characteristics of PICU patients who undergo a process of withholding or withdrawing life-sustaining treatment (LTSV), between 2004 y 2014. Patients and Method: A retrospective, observational descriptive study, using two documents for quality assessment in the PICU of Hospital Roberto del Río: 1) daily individual patient tracking log and 2) daily record of quality indicators, including LTSV, both updated daily at the morning visit. All PICU patients with an ethical dilemma during their PICU stay in which a LTSV was proposed were included. We men tion patients rejected for admission in the ICU and those who died in basic units of the hospital with LTSV. Results: In 118 patients of 7821 PICU admissions (1,5%) we determined a LTSV: ONR (Non Resuscitation Order) for all of them, ONI (Non Innovation Order) in 78,8%, withdrawal of some therapeutics in 14,4% and withdrawal of active mechanical ventilation in 6,8%. The basic diagnosis was 23,7% for each neurologic and oncologic diseases. The predominant pathophysiologic condition leading to a LTSV was severe chronic neurologic damage (39%). The length of stay was threefold the mean PICU stay, with a large variability due to expectable individual factors when ethic decisions are involved. Conclusion: LTSV is feasible when the team is involved and this perspective is part of daily clinical analysis. The wide individual variability in the LTSV process is expectable in ethical decisions.

Do not attempt resuscitation orders at the emergency department of a teaching hospital / Ordens de não ressuscitação no serviço de emergência de um hospital universitário

ABSTRACT Objective: To identify factors associated with not attempting resuscitation. Methods: A cross-sectional study conducted at the emergency department of a teaching hospital. The sample consisted of 285 patients; in that, 216 were submitted to cardiopulmonary resuscitation and 69 were not. The data were collected by means of the in-hospital Utstein Style. To compare resuscitation attempts with variables of interest we used the χ2 test, likelihood ratio, Fisher exact test, and analysis of variance (p<0.05). Results: No cardiopulmonary resuscitation was considered unjustifiable in 56.5% of cases; in that, 37.7% did not want resuscitation and 5.8% were found dead. Of all patients, 22.4% had suffered a previous cardiac arrest, 49.1% were independent for Activities of Daily Living, 89.8% had positive past medical/surgical history; 63.8% were conscious, 69.8% were breathing and 74.4% had a pulse upon admission. Most events (76.4%) happened at the hospital, the presumed cause was respiratory failure in 28.7% and, in 48.4%, electric activity without pulse was the initial rhythm. The most frequent cause of death was infection. The factors that influenced non-resuscitation were advanced age, history of neoplasm and the initial arrest rhythm was asystole. Conclusion: Advanced age, past history of neoplasia and asystole as initial rhythm were factors that significantly influenced the non-performance of resuscitation. Greater clarity when making the decision to resuscitate patients can positively affect the quality of life of survivors.

RESUMO Objetivo: Identificar fatores associados à não realização de ressuscitação. Métodos: Estudo transversal realizado no serviço de emergência de um hospital universitário. A amostra foi composta por 285 pacientes, dos quais 216 foram submetidos à ressuscitação cardiopulmonar, e 69 não tiveram esta conduta. Os dados foram coletados por meio do in-hospital Utstein Style. Para comparar as tentativas de ressuscitação e as variáveis de interesse, utilizaram-se o teste do χ2, a razão de verossimilhança, o teste exato de Fisher e a análise de variância (p<0,05). Resultados: A não ressuscitação foi considerada injustificável em 56,5% dos casos, sendo que 37,7% não queriam ressuscitação e 5,8% foram encontrados mortos. Do total de pacientes, 22,4% tiveram parada cardíaca prévia, 49,1% eram independentes para Atividades de Vida Diária, e 89,8% tinham alguma história pregressa; 63,8% estavam conscientes, 69,8% estavam respirando e 74,4% tinham pulso palpável à admissão. A maioria dos eventos (76,4%) ocorreu no hospital, e a causa presumida de parada foi insuficiência respiratória em 28,7% e, em 48,4%, o ritmo inicial foi atividade elétrica sem pulso. A causa mais frequente de morte foi infecção. Os fatores que influenciaram na não realização de ressuscitação foram idade avançada, história de neoplasia e assistolia como ritmo inicial de parada. Conclusão: Idade avançada, história de neoplasia e assistolia como ritmo inicial foram os fatores que influenciaram significativamente na não realização de ressuscitação. Maior clareza na decisão de reanimar pode afetar positivamente a qualidade de vida dos pacientes.

Limitación del esfuerzo terapéutico en cuidados intensivos pediátricos: conocimiento y actitudes bioéticas del profesional médico / Limitation of therapeutic effort in Paediatric Intensive Care Units: bioethical knowledge and attitudes of the medical profession

Los cuidados intensivos pediátricos son una especialidad nueva, con importantes avances tecnológicos que pueden prolongar el proceso de morir. Uno de los problemas bioéticos frecuentes es la limitación del esfuerzo terapéutico, que es la adecuación y/o proporcionalidad del tratamiento tratando de evitar obstinación y futilidad. OBJETIVO Conocer la experiencia de médicos que trabajan en unidades de cuidado intensivo (UCIP) ante decisiones ético-clínicas. SUJETOS Y MÉTODO Estudio observacional, descriptivo y transversal, aplicando una encuesta anónima a médicos de UCIP, solicitando datos sobre problemas éticos que se generan en la atención al niño crítico y su procedimiento de resolución. Aprobado por el Comité de Ética de la Investigación de la Facultad de Medicina de la Universidad del Desarrollo-Clínica Alemana. RESULTADOS Respondieron 126 médicos de 34 UCIP de Chile. El 98,41% ha tomado decisiones de limitación terapéutica. El tipo de limitación más frecuente mencionado fue la orden de no reanimar (n = 119), seguido por la no instauración de medicamentos (n = 113), limitación de ingreso a UCIP (n = 81), siendo la menos mencionada la retirada de tratamientos (n = 81). El 34,13% consideró que existían diferencias éticas entre no instaurar o retirar un determinado tratamiento. CONCLUSIONES Los dilemas ético-clínicos son comunes en la UCIP, siendo frecuentes las decisiones de limitación terapéutica. Muchos médicos reconocen no poseer conocimientos en ética clínica y necesitar formación continua en bioética.

Paediatric intensive care is a relatively new specialty, with significant technological advances that lead to the prolongation of the dying process. One of the most common bioethical problems is limitation of treatment, which is the adequacy and/or proportionality treatment, trying to avoid obstinacy and futility. OBJECTIVE To determine the experience of physicians working in Paediatric Intensive Care Units (PICU) when faced with bioethical decisions. SUBJECTS AND METHOD An observational, descriptive and cross-sectional study was conducted using an anonymous questionnaire sent to physicians working in PICU. The data requested was related to potential ethical problems generated in the care of the critical child, and the procedure for their resolution. The study was approved by the Ethics Research Committee of the Faculty of Medicine UDD CAS. RESULTS A total of 126 completed questionnaires were received from physicians working in 34 PICU in Chile. Almost all (98.41%) of them acknowledged having taken therapeutic limitation decisions (TLD). The most common type of TLD mentioned was the Do Not Resuscitate order (n = 119), followed by the establishment of no medications (n = 113), limited admission to PICU (n = 81), with the withdrawal of treatment being the least mentioned (n = 81). Around one-third (34.13%) felt that there were no ethical difference between introducing or removing certain treatments. CONCLUSIONS Bioethical dilemmas are common in the PICU, with therapeutic limitation decisions being frequent. Many recognise not having expertise in clinical ethics, and they need continuing education in bioethics.

cross-sectional study of knowledge and attitudes of medical professionals towards end-of-life decisions in teaching hospitals of Kandy District [Sri Lanka]

The aim of this study was to evaluate the knowledge and attitudes about Do Not Resuscitate orders, Advance Directives and Withdrawal or Withholding of life-sustaining therapy among medical professionals. Descriptive, cross-sectional study. The study was conducted in three teaching hospitals, General Hospital Kandy, Teaching Hospital Peradeniya and Teaching Hospital Gampola of Kandy District [Sri Lanka]. 232 medical professionals were randomly selected. Data were collected using a pre-tested self administered questionnaire. The knowledge and attitude was assessed with regard to 'Advance Directives', DNR orders and 'withdrawal/ withholding life sustaining care', by scenario based questions and several close-ended questions. Data were analyzed with SPSS v17.0 and Pearson Chi Square was calculated. The age range of the study population [n=232] was 26-56 years and majority of the participants were male [64.2%]. Most of the medical professionals were Buddhists [88.4%]. Out of the subjects, 66.8% [p<0.001] had heard the term 'DNR', while 26.3% knew the correct meaning and 68.1% [p<0.001] thought it to be ethical to practice it in Sri Lanka. The number of medical professionals feeling that patient, doctor or the family should have the right to decide on end-of-life decisions was 62.9% [p=0.005], 62.9% [p=0.005] and 46.6% [p=0.46] respectively. 20.7% had heard about 'Advance Directives' but only 12.1% knew the correct meaning; 62.5% had heard about 'withdrawal/withholding of life sustaining therapy' [p=0.006] and 65.9% opined that it should be implemented in Sri Lanka [p<0.001]. The knowledge about end-of-life decisions among medical professionals working in three major teaching hospitals of Kandy district is inadequate. The majority of the medical doctors have positive attitude towards end-of-life decisions implementation in Sri Lanka

Orden de no reanimar, consideraciones sobre este problema / Don not resuscitate order: some considerations about this problem

El artículo define aspectos y significados clínicos y éticos sobre Paro Cardiorrespiratorio (PCR), Maniobras de Reanimación Cardiopulmonar y Orden de No resucitación Cardiopulmonar (No-RCP). Enfatiza la diferencia entre el cese de la función cardiorrespiratoria por muerte natural (p.ej. por enfermedad crónica irreversible), distinguiéndolo de el PCR súbito, reversible. Se examinan estas situaciones a la luz de los “Fines de la Medicina” (Hastings Center, 1996).Se analizan los principales problemas, comenzando por las dificultades según los diferentes escenarios (servicio de urgencia, pabellón de maternidad, sala de hospitalizados, unidad de intensivo, pabellones quirúrgicos); se analiza la incertidumbre sobre el pronóstico de cada pacientes y sobre quién(es) deben tomar las decisiones sobre el fin de la vida. Idealmente debe ser el paciente autónomo quien tome la decisión, pero en otros casos se requieren alternativas, una de ellas es la Orden Unilateral. Otros problemas son la Validez de las órdenes de no-RCP en los diferentes tiempos evolutivos, el problema de la Futilidad y la Validez de las “Directivas Anticipadas”, en este grupo resalta el enfoque POLST (Physician’s Order for Life Sustaining Treatment) como más comprehensivo; como complemento ha surgido también el concepto AND (Allow Natural Death), que podría estar destinado a remplazar la orden de no-RCP (DNR).

This article examines the ethical and clinical significance of Cardiopulmonary Arrest, Cardiopulmonary Resuscitation maneuvers and Do Not Resuscitate Order (DNR). It emphasizes Cardiopulmonary Arrest, Cardiopulmonary Resuscitation maneuvers and Do Not Resuscitate Order (DNR). It emphasizes the difference between the cessation of cardiorespiratory function by natural death (e.g. by chronic irreversible disease) as different from the sudden, reversible cardiopulmonary arrest. It considers these situations under the light of the “Goals of Medicine” (Hastings Center, 1996). We look through the main problems, in first place the specific difficulties according to different scenarios (emergency room, maternity ward, hospital room, intensive care unit, surgical blocks); second we analyzes the uncertainty about patients prognosis and third the controversial issue about who should take charge the end of life decisions. The autonomous patient should ideally be who takes the decisions. Other cases need alternatives ways, one of them is the “Unilateral Order”. Other problems are the validity of the DNR orders in different clinical times, the problem of futility and the value of Advance Directives; in this last point POLST (Physician’s Order for Life Sustaining Treatment) approach appears as more comprehensive; at last, the new concept AND (allow natural death) could be destined to replace the DNR order.

Decisiones críticas en Anestesiología / Critical Decisions in Anesthesiology

Cada vez son màs los anestesiòlogos que reconocen casos de dilemas éticos en su pràctica diaria. En este reporte de caso se presentan algunos fundamentos èticos para un debate urgente y necesario de anestesia en el que se requieren que las decisiones diarias tengan en cuenta los principios éticos y eviten la futilidad.

La reanimación cardiorrespiratoria y la orden de no reanimar / Cardiopulmonary resuscitation and do not resuscitate orders

In medical practice, the different scenarios in which cardio respiratory resuscitation (CPR) may be applied must be taken into account. CPR is crucial in subjects that arrive in emergency rooms or suffer a cardiac arrest in public places or at their homes. It is also critical in hospitalized patients with potentially reversible diseases, who suffer cardiac arrest as an unexpected event during their evolution. In intensive care units, the decision is particularly complex. The concepts of therapeutic proportionality, treatment futility and therapeutic tenacity can help physicians in their decision making about when CPR is technically and morally mandatory. The do not resuscitate (DNR) decision in taken when a patient is bearing an irreversible disease and his life is coming to an end. DNR decisions are clearly indicated in intensive care units to limit the therapeutic effort and in other hospital facilities, when death is foreseeable and therapeutic tenacity must be avoided. DNR orders must be renewed and reconsidered on a daily basis. It does not mean that other treatment should be discontinued and by no means should the patient be abandoned. DNR and previous directives, DNR and quality of life and DNR communication are also commented in the present article.
