Risk Factors and Outcomes After a Brief Resolved Unexplained Event: A Multicenter Study.

BACKGROUND: The accuracy of the risk criteria for brief resolved unexplained events (BRUEs) from the American Academy of Pediatrics (AAP) is unknown. We sought to evaluate if AAP risk criteria and event characteristics predict BRUE outcomes. METHODS: This retrospective cohort included infants <1 year of age evaluated in the emergency departments (EDs) of 15 pediatric and community hospitals for a BRUE between October 1, 2015, and September 30, 2018. A multivariable regression model was used to evaluate the association of AAP risk factors and event characteristics with risk for event recurrence, revisits, and serious diagnoses explaining the BRUE. RESULTS: Of 2036 patients presenting with a BRUE, 87% had at least 1 AAP higher-risk factor. Revisits occurred in 6.9% of ED and 10.7% of hospital discharges. A serious diagnosis was made in 4.0% (82) of cases; 45% (37) of these diagnoses were identified after the index visit. The most common serious diagnoses included seizures (1.1% [23]) and airway abnormalities (0.64% [13]). Risk is increased for a serious underlying diagnosis for patients discharged from the ED with a history of a similar event, an event duration >1 minute, an abnormal medical history, and an altered responsiveness (P < .05). AAP risk criteria for all outcomes had a negative predictive value of 90% and a positive predictive value of 23%. CONCLUSIONS: AAP BRUE risk criteria are used to accurately identify patients at low risk for event recurrence, readmission, and a serious underlying diagnosis; however, their use results in the inaccurate identification of many patients as higher risk. This is likely because many AAP risk factors, such as age, are not associated with these outcomes.

[Application of a new terminology "BRUE: Brief, resolved and unexplained events". Definitions and recommendations]. / Aplicación de una nueva terminología "BRUE: Eventos breves, resueltos e inexplicados". Definiciones y recomendaciones.

Three decades ago, the term Apparent Life-Threatening Events (ALTE) was proposed and was gra dually incorporated into the clinical approach of these patients, allowing to determine risks, attribute causes, and perform specific treatments. However, this led to studies and hospitalizations considered unnecessary in many cases, increasing health costs. For this reason, the concept of Brief Resolved Unexplained Events (BRUE) was created, in order to reduce the subjectivity of the event and focus a management strategy according to the risk determination. This article analyzes the differences bet ween ALTE and BRUE according to international and Chilean consensus, deepening the approach and incorporating relevant considerations for the daily clinical practice with infants who present a BRUE.

Resumen: Hace tres décadas se propuso el término Apparent Life-Threatening Events (ALTE), siendo incorpo rado paulatinamente en el enfrentamiento clínico de estos pacientes; permitiendo determinar riesgos, atribuir causas y realizar tratamientos específicos. Sin embargo, llevó a realizar estudios y hospitalizaciones en muchas instancias considerados innecesarios, generando un aumento de los costos sanitarios. Por estos motivos nace el concepto de Brief Resolved Unexplained Events (BRUE), que pretende disminuir la subjetividad del evento y focalizar una estrategia de manejo según determina ción del riesgo. En el siguiente artículo se analizan diferencias entre ALTE y BRUE según consensos internacionales y chilenos, profundizando en el enfrentamiento e incorporando consideraciones de relevancia para la práctica clínica cotidiana de lactantes que presentan un BRUE.

Brief Resolved Unexplained Events: Analysis of an Apparent Life Threatening Event Database.

OBJECTIVE: To identify the proportion of patients previously diagnosed with apparent life-threatening events (ALTE) who would meet criteria for brief resolved unexplained events (BRUE) and to identify rates of adverse outcomes in subgroups: ALTE not meeting criteria for BRUE, lower-risk BRUE, and higher-risk ALTE. METHODS: We performed a secondary analysis of a single-center prospective registry of patients diagnosed with ALTE in a tertiary care emergency department from March 1, 1997 to October 31, 2007. We identified the proportion of patients meeting criteria for BRUE, and the proportion of patients with BRUE meeting lower-risk criteria. We assessed outcomes of patients in subgroups. RESULTS: Seven hundred and sixty-two patients were included. Adverse outcomes included recurrent ALTE (n = 49), aspiration (n = 9), trauma (n = 8), and death (n = 4). Three hundred and twenty-six of 762 (42.8%) met criteria for BRUE. Seventy of 326 (21.5%) met criteria for lower-risk BRUE. Adverse outcomes occurred in 40 of 436 (9.2%) with ALTE not meeting criteria for BRUE, 2 of 70 (2.9%) with lower-risk BRUE, and 23 of 256 (9.0%) with higher-risk BRUE. Of 4 patients who died, 1 had an ALTE not meeting criteria for BRUE and 3 had non-lower-risk BRUE. The BRUE risk criteria identified all BRUE patients that died or had substantial morbidity as higher-risk. CONCLUSIONS: Less than half of patients with ALTE meet criteria for BRUE. Of those who do, one-fifth is lower-risk. In this series, the risk-stratification in the BRUE criteria identified those patients at highest risk of adverse outcomes. Further research is required to risk-stratify patients with BRUE.

Physicians' attitudes when faced with life-threatening events in children with severe neurological disabilities.

PURPOSE: Children with severe neurological disabilities are at an increased risk of acute, life-threatening events. We assessed physicians' attitudes when making decisions in these situations. METHODS: We surveyed physicians in pediatric intensive care, neurology, and rehabilitation units in Swiss hospitals. The questionnaire explored participants' attitudes toward life-threatening situations in two scenarios: a child with profound intellectual and multiple disabilities (PIMD) and an infant with spinal muscular atrophy (SMA) type I. RESULTS: The participation rate was 55% (52/95). There was a consensus favoring non-invasive ventilation and comfort care as well as avoiding tracheostomy and invasive ventilation. For the child with PIMD, 61% of participants opposed cardiopulmonary resuscitation (CPR), 51% for the child with SMA. Physicians with over 20 years of experience were significantly more opposed to providing CPR than less experienced colleagues. CONCLUSIONS: Physicians held different views, influenced by personal factors. This highlights the importance of standardizing multidisciplinary processes toward approaching these complex situations.

Portable, non-powered, suction-generating device for management of life-threatening aerodigestive tract foreign bodies: Novel prototype and literature review.

OBJECTIVE: To present a novel approach for the emergent, pre-hospital management of life-threatening aerodigestive tract foreign body aspiration using a portable, non-powered, suction-generating device (PNSD), in the context of a literature review of emergent pre-hospital management of patients with foreign body airway obstruction. METHODS: The PubMed and MEDLINE databases were comprehensively screened using broad search terms. A literature review of pre-hospital management and resuscitative techniques of foreign body airway obstruction was performed. Further, independent measurements of PNSD pressure generation were obtained. Application of a PNSD in cadaveric and simulation models were reviewed. A comparative analysis between a PNSD and other resuscitative techniques was performed. RESULTS: Physiologic data from adult and pediatric human, non-human, and simulation studies show pressure generation ranging from 5.4 to 179 cm H2O using well-established resuscitative maneuvers. Laboratory testing demonstrated that a protypic PNSD demonstrated peak airway pressures of 434.23 ±â€¯12.35 cm H2O. A simulation study of a PNSD demonstrated 94% reliability in retrieving airway foreign body, while a similar cadaveric study demonstrated 98% reliability, with both studies approaching 100% success rate after multiple attempts. Several case reports have also shown successful application of PNSD in the emergent management of airway foreign body in elderly and disabled patients. CONCLUSION: PNSDs may play an important role in the emergent, non-operative, pre-hospital management of upper aerodigestive tract foreign body aspiration, particularly in settings and populations with high choking risk. Further characterization of effectiveness and safety in larger cadaveric or simulation studies mimicking physiologic conditions is indicated.

Unidad de niños con patología crónica compleja. Un modelo necesario en nuestros hospitales / Children's medically complex diseases unit. A model required in all our hospitals

Introducción: El incremento de la supervivencia de niños con enfermedades graves ha supuesto el aumento de niños con patología crónica altamente compleja, en ocasiones con discapacidades de por vida. En el año 2008 se creó una unidad para la atención específica de los niños con patología crónica compleja (NPCC) en el Hospital La Paz. Objetivos: Describir el funcionamiento y la actividad asistencial de esta unidad. Pacientes y métodos Se analizaron todos los informes de alta de la unidad entre enero de 2014 y julio de 2016. Resultados: La unidad dispone de consulta y 6 camas de hospitalización. Se han atendido 1.027 pacientes, 243 desde 2014. La mediana de edad fue de 24,2 meses (IC: 10,21-84,25). Un 92,59% presentaron pluripatología, siendo las condiciones crónicas más frecuentemente observadas las neurológicas (76,95%), gastrointestinales (63,78%) y respiratorias (61,72%). Un 69,54% de los NPCC fueron dependientes de tecnología, el 53,49% de soporte respiratorio y el 35,80% nutricional. El número de ingresos ha aumentado anualmente, hasta 403 desde 2014, con un 8,93% de reingresos. La mediana de la estancia fue de 6 días (IC: 3-14). La tasa de ocupación fue superior al 100% en este período. En la actualidad se mantienen en seguimiento 210 pacientes (86,42%), 11 niños han sido dados de alta a sus hospitales de referencia y 22 han fallecido (9,05%). De estos 22 pacientes, la principal condición fue neurológica, y la principal causa desencadenante del fallecimiento fue infecciosa. Conclusión: La unidad de NPCC ha incrementado su actividad en estos años, poniendo de manifiesto la necesidad de crear estas unidades en los hospitales terciarios (AU)

Introduction: The increase in survival of children with severe diseases has led to the rise of children with chronic diseases, sometimes with lifelong disabilities. In 2008, a unit for the specific care of medically complex children (MCC) was created in Hospital La Paz. Objectives: To describe the work and care activities of this Unit. Patients and methods An analysis was performed on all discharge reports of the Unit between January 2014 and July 2016. Results: The MCC Unit has 6 beds and daily outpatient clinic. A total of 1,027 patients have been treated since the creation of the unit, with 243 from 2014. The median age was 24.2 months (IQ: 10.21-84.25). The large majority (92.59%) have multiple diseases, the most frequent chronic conditions observed were neurological (76.95%), gastrointestinal (63.78%), and respiratory diseases (61.72%). More than two-thirds (69.54%) of MCC are dependent on technology, 53.49% on respiratory support, and 35.80% on nutritional support. Hospital admission rates have increased annually. There have been 403 admissions since 2014, of which 8.93% were re-admissions within 30 days of hospital discharge. The median stay during 2014-2016 was 6 days (IQ: 3-14). The occupancy rate has been above 100% for this period. Currently, 210 patients remain on follow-up (86.42%), and 11 children (4.53%) were discharged to their referral hospitals. The mortality rate is 9.05% (22 deaths). The main condition of these 22 patients was neurological (9 patients). Infectious diseases were the leading cause of death. Conclusion: MCC should be treated in specialized units in tertiary or high-level hospitals (AU)

Background. There is no accepted consensus for the approach to apparent life-threatening events (ALTE), resulting in major variability in its management. Objective. The aim of the Apparent Life-Threatening Events Working Group (ALTEWG) of the Catalan Society of Pediatrics was to elaborate a consensus algorithm to be used in Catalan hospitals. Method. The ALTEWG designed an algorithm for the approach of ALTE that did not include newborns admitted in neonatal units. Professionals of different pediatric subspecialties participated in the development of the guidelines. The algorithm was based on a literature review and a consensus among the ALTEWG members, and included the management in the emergency room, admission criteria, and indication of diagnostic studies. The algorithm was sent to 48 professionals of 40 Catalan hospitals in July of 2015 for further discussion. Results. Twenty-one responses from 17 hospitals were received. Five responders accepted the algorithm, while 16 made comments or proposed modifications. The ALTEWG evaluated all the responses and some modifications to the algorithm were subsequently made. Conclusions. The ALTEWG elaborated a consensus algorithm among Catalan hospitals that will allow for the implementation of a homogeneous approach to patients with ALTE (AU)

Pediatric emergencies admitted in the resuscitation room of a Swiss university hospital.

OBJECTIVES: Pediatric resuscitation is an intense, stressful, and challenging process. The aim of this study was to review the life-threatening pediatric (LTP) emergencies admitted in a Swiss university hospital with regards to patients' demographics, reason for admission, diagnosis, treatment, significant events, critical incidents, and outcomes. METHODS: A retrospective observational cohort study of prospectively collected data was conducted, including all LTP emergencies admitted over a period of 2 years in the resuscitation room (RR). Variables, including indication for transfer, mode of prehospital transportation, diagnosis, and time spent in RR, were recorded. RESULTS: Of the 60,939 pediatric emergencies treated in our university hospital over 2 years, a total of 277 LTP emergencies (0.46%) were admitted in the RR. They included 160 boys and 117 girls, aged 6 days to 15.95 years (mean, 6.69 years; median, 5.06). A medical problem was identified in 55.9% (n = 155) of the children. Of the 122 children treated for a surgical problem, 35 (28.3%) went directly from the RR to the operating room. Hemodynamic instability was noted in 19.5% of all LTP emergencies, of which 1.1% benefited from O negative transfusion. Admission to the intensive care unit was necessary for 61.6% of the children transferred from another hospital. The average time spent in the RR was 46 minutes. The overall mortality rate was 7.2%. CONCLUSIONS: The LTP emergencies accounted for a small proportion of all pediatric emergencies. They were more medical than surgical cases and resuscitation measures because of hemodynamic instability were the most frequent treatment.

Consenso sobre el manejo de eventos de aparente amenaza a la vida del lactante (ALTE): comisión de sueño, sociedad chilena de neumología pediátrica 2013 / Consensus on evaluation and management of apparent life-threatening events in infancy (ALTE)

Un Evento de Aparente Amenaza de la Vida o ALTE (del inglés: Apparent Life Threatening Event) corresponde a un episodio agudo que ante los ojos del observador pone en riesgo la vida de un lactante menor de 1 año. Debe presentar la combinación de 2 o más de los criterios siguientes: apnea / cambio de color / alteración del tono / atoro e implicar la necesidad de algún tipo de maniobras para reanimar. En el presente consenso sobre el manejo de un ALTE se revisaron la evidencia internacional y nacional respecto al enfoque diagnóstico, estudio etiológico, criterios y duración de hospitalización y las indicaciones de monitorización domiciliaria.

Apparent life threatening events are defined as an acute episode in which the observer fears an infant < 1 year may die. ALTE is characterized by some combination of apnea, color or muscle tone change, chocking and has to be followed by cardiorespiratory reanimation. The present consensus paper reviews international and national evidence concerning diagnosis, etiologies, hospitalization criteria and indications for home monitoring.

[Severe apparent life-threatening event during "skin-to-skin": treatment with hypothermia]. / Episodio aparentemente letal neonatal durante el «piel con piel¼. Tratamiento con hipotermia.

'Skin-to-skin' in healthy newborn infants is currently routine practice in Spanish maternity wards. This practice has shown benefits in increasing the duration of breast-feeding and maternal bonding behaviour with no significant adverse events. Early sudden deaths and severe apparent life-threatening events (ALTE) during the first 24 hours of life are infrequent, but well recognised. Risk factors during 'skin to skin' have been established. These events can lead to high neonatal morbidity and mortality. Hypothermia is now the standard of care for moderate to severe hypoxic-ischaemic encephalopathy and has shown to reduce mortality and neurological morbidity in children with hypoxic-ischaemic brain injury. Although there are no clinical trials that evaluate hypothermia after a severe ALTE, neonates who suffer it should be considered for this treatment. We present a case of a healthy newborn who had an ALTE during skin-to-skin with his mother and was treated with hypothermia.

[An apparent life threatening secondary to long Qt syndrome]. / Aparente amenaza para la vida por el síndrome de QT prolongado.

We report the case of an infant with an episode of loss of consciousness, in whom ventricular fibrillation was diagnosed. He was successfully defibrillated and long QT syndrome was diagnosed as his baseline disease. This case constitutes a documented example of this entity as a cause of the sudden infant death syndrome.

Ethanol ingestion in two infants under 2 months old: a previously unreported cause of ALTE.

The differential diagnosis for the infant presenting with an apparent life-threatening event (ALTE) is broad. Toxic ingestions are a relatively uncommon cause of an ALTE, although several over-the-counter, prescription, and illicit drugs have been implicated. We present 2 cases of ethanol intoxication in infants as a previously unreported cause of an ALTE. Additionally, serial ethanol levels for these patients offer novel insight into the pharmacokinetics of ethanol metabolism in infants. Ethanol ingestion may be an underrecognized cause of an ALTE and should be considered if the history or physical examination is suggestive.
