Differences in the yield of the implantable loop recorder between secondary and tertiary centers.

BACKGROUND: The implantable loop recorder (ILR) is a useful tool for diagnosis of syncope or palpitations. Its easy use and safety have extended its use to secondary hospitals (those without an Electrophysiology Lab). The aim of the study was to compare results between secondary and tertiary hospitals. METHODS: National prospective and multicenter registry of patients with an ILR inserted for clinical reasons. Data were collected in an online database. The follow-up ended when the first diagnostic clinical event occurred, or 1 year after implantation. Data were analyzed according to the center of reference; hospitals with Electrophysiology Lab were considered Tertiary Hospitals, while those hospitals without a lab were considered Secondary Hospitals. RESULTS: Seven hundred and forty-three patients (413 [55.6%] men; 65 ± 16 year-old): 655 (88.2%) from Tertiary Centers (TC) and 88 (11.8%) from Secondary Centers (SC). No differences in clinical characteristics between both groups were found. The electrophysiologic study and the tilt table test were conducted more frequently in Tertiary Centers. Follow-up was conducted for 680 (91.5%) patients: 91% in TC and 94% in SC. There was a higher rate of final diagnosis among SC patients (55.4% vs. 30.8%; p < 0.001). Tertiary Hospital patients showed a trend towards a higher rate of neurally mediated events (20% vs. 4%), while bradyarrhythmias were more frequent in SC (74% vs. 60%; p = 0.055). The rate of deaths and adverse events was similar in both populations. CONCLUSIONS: Patients with an ILR in SC and TC have differences in terms of the use of complementary tests, but not in clinical characteristics. There was a higher rate of diagnosis in Secondary Hospital patients.

Manejo del síncope en el servicio de urgencias sin ingreso hospitalario: utilidad de un protocolo coordinado con la unidad de arritmias / Management of syncope in the emergency department without hospital admission: usefulness of an arrhythmia unit coordinated protocol

Introducción y objetivos. El principal objetivo de este estudio es demostrar que un protocolo para el manejo del síncope en el servicio de urgencias basado en la detección precoz de cardiopatía permite diagnosticar a los pacientes de forma rápida y con una baja proporción de ingresos, sin que ello repercuta de forma negativa en su pronóstico. Métodos. El estudio se realizó de forma prospectiva en 199 pacientes consecutivos (54% varones; media de edad, 67 ± 17 años) que acudieron por síncope al servicio de urgencias de nuestro hospital en un período de 17 meses. Se desarrolló un algoritmo diagnóstico en dos pasos en el que los pacientes eran sometidos a una primera evaluación clínica y electrocardiográfica y posteriormente a un protocolo diagnóstico basado en la realización secuencial de pruebas diagnósticas en el servicio de urgencias, con lo que se evitó su ingreso hospitalario. Resultados. Tras la valoración inicial, se diagnosticó a 120 (60%) pacientes. Después de completado el protocolo, se obtuvo clasificación diagnóstica del 78% de los pacientes, con una estancia media en el servicio de urgencias de 19 ± 15 h; se ingresó al 10% de los pacientes. Con un seguimiento medio de 237 días, fallecieron 3 pacientes. Conclusiones. El manejo protocolizado del síncope en el servicio de urgencias basado en una estratificación de los pacientes según tengan o no cardiopatías permite el diagnóstico de una elevado porcentaje de pacientes y dar de alta a la mayoría de forma rápida desde el mismo servicio de urgencias, sin que ello repercuta de forma negativa en su pronóstico a medio plazo (AU)

Introduction and objectives. The main aim of this study was to demonstrate that a protocol for managing syncope in the emergency department that is based on the early detection of heart disease enables patients to be diagnosed quickly and with few admissions, without there being a negative impact on prognosis. Methods. The study was performed prospectively in 199 consecutive patients (54% male; mean age, 67 [17] years) who presented with syncope at the emergency department of our hospital during a 17-month period. A two-step diagnostic algorithm was developed in which patients initially underwent clinical and electro-cardiographic assessment, and thereafter were submitted to a diagnostic protocol that involved carrying out a sequence of diagnostic tests in the emergency room to avoid hospital admission. Results. A presumptive diagnosis was established in 120 (60%) patients during the initial assessment. After completion of the diagnostic protocol, 78% of patients were given a clear diagnosis within a mean stay of 19 [15] h in the emergency department. Some 10% of patients were admitted. Three patients died during a mean follow-up period of 237 days. Conclusions. Implementation of a protocol for managing syncope in the emergency department that was based on screening patients according to the presence of heart disease enabled a large percentage to receive a diagnosis. Moreover, the majority of patients could be discharged rapidly from the emergency department without there being any negative impact on medium-term prognosis (AU)
