Diferencias de sexo en los beneficios de la anticoagulación en pacientes ancianos con fibrilación auricular: un subanálisis del estudio EMERG-AF / Sex-related differences in benefits of anticoagulation therapy in elderly patients with atrial fibrillation: a subanalysis of the EMERG-AF study

Objetivos: Analizar los beneficios y seguridad a largo plazo de la anticoagulación oral (ACO) prescrita en los servicios de urgencias (SU) a pacientes mayores con fibrilación auricular (FA) y las diferencias en función del sexo. Método: Se trata de un análisis post-hoc del estudio EMERG-AF. Se incluyeron pacientes consecutivos $ 75 años, que consultaron en 62 SU por FA. Se recogieron datos clínicos y ACO. La variable principal estuvo compuesta por muerte, tromboembolia o sangrado mayor en 1 año. Resultados: Se incluyeron 690 pacientes, 386 mujeres (55,9%). Al alta, 575 pacientes (83,3%) estaban con ACO. En 96 de ellos se inició en el SU. Tras 1 año, la variable principal sucedió en 158 pacientes (22,9%): 118 (17,1%) fallecieron, 22 (2,7%) tuvieron una complicación tromboembólica y 34 (4,9%) una hemorragia mayor. Tras ajustar por las principales características clínicas, la ACO se asoció a una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p < 0,001), pero no se asoció con la hemorragia mayor. En las mujeres, la ACO se asoció con una reducción en la variable principal (HR: 0,372, IC 95%: 0,236-0,587, p < 0,001) y una menor mortalidad (HR: 0,281, IC 95%: 0,168-0,469, p < 0,001), incluidos pacientes con nueva prescripción y en aquellos dados de alta. Esta asociación no alcanzó significación en los hombres. (AU)

Objectives: To analyze the long-term benefits and safety of oral anticoagulation therapy prescribed in emergency departments for elderly patients with atrial fibrillation, and to detect any sex-related differences present. Material and methods: Post-hoc analysis of data compiled by the EMERG-AF group (Spanish acronym for Emergency Department Stroke Prophylaxis and Guidelines Implementation in Atrial Fibrillation). Consecutive patients aged 75 years or older with atrial fibrillation who were treated in 62 EDs were included. We recorded clinical data and anticoagulants prescribed. Patients were followed for 1 year. The main outcome variable was a composite of death, thromboembolism, or major bleeding within 1 year. Results: Data for 690 patients were registered; 386 (55.9%) were women. At discharge, 575 patients (83.3%) were on anticoagulants; therapy was started in the ED for 96 of them. A total of 158 patients (22.9%) had experienced at least 1 component of the main outcome within 1 year: 118 (17.1%) died, 22 (2.7%) had thromboembolic complications, and 34 (4.9%) had major bleeding. After adjustment for main clinical characteristics, hazard ratios (HRs) showed that anticoagulation therapy was associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) but not specifically with major bleeding overall. When data for women were analyzed separately, anticoagulant therapy was again associated with a reduction in the composite outcome (HR, 0.372; 95% CI, 0.236-0.587; P .001) and also with death (HR, 0.281; 95% CI, 0.168-0.469; P .001), even in patients with anticoagulant prescriptions initiated on discharge from the ED. These associations did not reach statistical significance in men. (AU)

These associations did not reach statistical significance in men. CONCLUSION: ED anticoagulant prescription for elderly patients with atrial fibrillation is safe and contributes to a reduction in mortality. Women in this age group benefited more than men from starting anticoagulation during the acute phase in the ED.

En este grupo etario, las mujeres se benefician más que los hombres de iniciar la ACO en la fase aguda.

Long-term prognosis and emergency management for patients with an implantable cardioverter defibrillator: the EMERGE-ICD study. / Estudio EMERG-ICD: manejo y pronóstico a largo plazo de las urgencias en los pacientes portadores de un desfibrilador automático implantable.

OBJECTIVES: Patients with implantable cardioverter defibrillators (ICDs) are at risk of serious complications that are often treated in hospital emergency departments (EDs). The EMERG-ICD study (Emergency Department Management and Long-term Prognosis for Patients with ICDs) analysed management and long-term prognosis of ED patients with an ICD after an acute clinical event. MATERIAL AND METHODS: Observational multicenter cohort study including consecutive adult patients with ICDs who came to 27 hospital EDs in Spain for treatment and were followed for 10 years. We collected clinical variables on presentation, ED case management variables, and the date and cause of death in each case. The primary outcome variable was all-cause mortality. RESULTS: Five-hundred three patients were studied; 471 had structural heart disease (SHD) and 32 had primary electrical heart disease (PEHD). Beta-blockers were prescribed in the ED for 55% of the patients for whom they were indicated. Twenty-four (4.8%), 75 (15.7%), and 368 (73.2%) patients died during follow-up at 1 month, 1 year, and 10 years, respectively. Of these, 363 (77.1%) had SHD and 5 (15.6%) had PEHD (hazard ratio, 8.05 (95% CI, 3.33- 19.46). Among patients with SHD, the cause of death was cardiovascular in 66%. Mortality correlated significantly with seeking care for cardiovascular symptoms, advanced age, male sex, diabetes, a New York Heart Association score of 2 or more, severe ventricular dysfunction, and long-term amiodarone therapy. CONCLUSION: Prognosis after an acute clinical event is poor in patients with SHD and ICDs, mainly due to cardiovascular causes, especially among patients with associated comorbidities and cardiovascular complaints. Mortality is lower in patients with PEHD.

OBJETIVO: Los pacientes portadores de desfibriladores automáticos implantables (DAI) tienen riesgo de complicaciones graves que son atendidas con frecuencia en los servicios de urgencias hospitalarios (SUH). Este estudio analiza el manejo y el pronóstico de las urgencias en portadores de un DAI. METODO: Estudio de cohorte observacional y multicéntrico que incluyó de manera consecutiva pacientes adultos portadores de DAI que consultaron en 27 SUH en España, con seguimiento posterior a 10 años. Se recogieron las variables clínicas, manejo en el SUH, fecha y causa del fallecimiento. La variable de resultado primaria fue la mortalidad por cualquier causa. RESULTADOS: Se incluyeron 503 pacientes, 471 con cardiopatía estructural (CE) y 32 con enfermedad eléctrica primaria cardiaca (EEPC). Se prescribió betabloqueantes en el SUH al 55% de los pacientes con indicación. Durante el seguimiento fallecieron 24 (4,8%), 75 (15,7%) y 368 pacientes (73,2%) a 1 mes, 1 año y 10 años, respectivamente. De estos, 363 tenían CE y 5 EEPC (77,1% vs 15,6%, HR 8,05 IC 95% 3,33-19,46). Entre los pacientes con CE, la mortalidad global fue de causa cardiovascular en el 66% de los casos. La mortalidad se asoció significativamente con la consulta por una causa cardiovascular, edad avanzada, sexo masculino, diabetes, NHYA 2, disfunción ventricular grave y tratamiento crónico con amiodarona. CONCLUSIONES: El pronóstico de los portadores de DAI con CE es muy adverso, fundamentalmente debido a complicaciones cardiovasculares en pacientes con comorbilidades que consultan por sintomatología cardiovascular. La mortalidad es menor en los pacientes con EEPC.

Análisis del tratamiento para mantener el ritmo sinusal en pacientes con fibrilación auricular prescrito en los servicios de urgencias: subanálisis del estudio HERMES-AF / Emergency department prescription of sinus rhythm maintenance therapy for patients treated for atrial fibrillation: a secondary analysis of the HERMES-AF study

Objetivo. El mantenimiento del ritmo sinusal (RS) con fármacos antiarrítmicos (FAA) y/o tratamiento del remodelado (TRM) es parte fundamental en la estrategia de control del ritmo en la fibrilación auricular (FA). Este estudio analiza estas estrategias y su adecuación en los servicios de urgencias hospitalarios (SUH). Método. Análisis secundario del estudio multicéntrico observacional transversal HERMES-AF, desarrollado en 124 SUH representativos del sistema sanitario español en 2011. Se incluyeron pacientes consecutivos con FA que revirtieron a RS y fueron dados de alta desde urgencias. Resultados. Se incluyeron 449 pacientes: 204 (45,4%) ya realizaban tratamiento para mantenimiento del RS. De los 245 restantes se prescribió tratamiento en el SUH a 107 (43,7%): 41 con FAA, 19 TRM y en 47 ambas terapias. En 10 casos (11,8%) la selección del FAA no era acorde a las recomendaciones de las guías. La prescripción de FAA se asoció a FA previa [odds ratio (OR) 2,024, IC 95%: 1,196-3,424, p = 0,009], frecuencia cardiaca > 110 lpm (OR 2,147, IC 95%: 1,034-4,456, p = 0,040) y anticoagulación al alta (OR 1,862, IC 95%: 1,094-3,170, p = 0,022). El TRM se asoció a frecuencia cardiaca > 110 lpm (OR 2,187, IC 95%: 1,005-4,757, p = 0,018). En total, al alta del SUH 311 pacientes (69,2%) recibían tratamiento para mantenimiento del RS (87 con FAA, 117 con TRM y 107 con ambas terapias). Conclusiones. La prescripción de tratamiento para evitar las recurrencias de la FA es insuficiente en los SUH. Extender esta prescripción y mejorar la adecuación del tratamiento antiarrítmico son áreas de mejora de la estrategia de control del ritmo en los SUH.

Background and objective. The maintenance of sinus rhythm by means of antiarrhythmic drugs and/or upstream therapy to counter cardiac remodeling is fundamental to the management of atrial fibrillation (AF). This study aimed to analyze this approach and its appropriateness in the setting of hospital emergency departments. Methods. Secondary analysis of data from the multicenter observational cross-sectional HERMES-AF study carried out in 124 hospitals representative of the Spanish national health service in 2011. Included were consecutive patients with AF restored to sinus rhythm who were discharged home from emergency care. Results. A total of 449 patients were included; 204 (45.4%) were already on sinus rhythm maintenance therapy. Of the 245 remaining patients, 107 (43.67%) were prescribed maintenance treatment in the emergency department, as follows: 41, an antiarrhythmic drug; 19, upstream therapy; and 49, both treatments. The selection of an antiarrhythmic drug did not follow guideline recommendations in 10 patients (11.8%). Antiarrhythmic drug prescription was associated with having had a prior episode of AF (odds ratio [OR], 2.024; 95% CI, 1.196-3.424; P = .009); a heart rate of more than 110 beats/min (OR, 2.147; 95% CI, 1.034-4.456, P = 0.40); and prescription of anticoagulation on discharge (OR, 1.862; 95% CI, 1.094-3.170; P = .022). Upstream therapy prescription was associated only with a heart rate over 110 beats/min (OR, 2.187; 95% CI, 1.005-4.757; P = .018). In total, 311 patients (69.23%) were discharged from the emergency department with sinus rhythm maintenance therapy: 87 with an antiarrhythmic drug, 117 with an upstream therapy, and 107 with both. Conclusions. Treatment to prevent the recurrence of AF is underprescribed in emergency departments. Increasing such prescription and ensuring the appropriateness of antiarrhythmic therapy prescribed are points emergency departments can improve in the interest of better sinus rhythm maintenance.

Factors associated with poor prognosis in patients with atrial fibrillation: An emergency department perspective the EMERG-AF study.

OBJECTIVE: We sought to identify the factors associated with a worse prognosis in Emergency Department (ED) patients with atrial fibrillation (AF), crucial information to guide management decisions. METHODS: This is a secondary analysis of a prospective, multicenter, observational cohort of consecutive AF patients attended in 62 EDs in Spain. Clinical variables were collected on enrollment. Follow-up was performed at 30 days and one year. The primary composite outcome was all-cause mortality, major bleeding and/or stroke at one year. Secondary outcomes were each of these components considered separately, plus one-year cardiovascular mortality and the composite outcome at 30 days. RESULTS: We analyzed 1107 patients. The primary outcome occurred in 209 patients (18.9%), one-year all-cause mortality in 151 (13.6%), major bleeding in 47 (4.2%), and stroke in 31 (2.8%). Disability (HR 2.064, 95% CI 1.478-2.882), previous known AF (HR 1.829, 95% CI 1.096-3.051), long duration of the AF episode (HR 1.849, 95% CI 1.052-3.252) and renal failure (HR 2.073, 95% CI 1.433-2.999) were independently associated with the primary outcome, whereas anticoagulation at discharge was inversely associated (HR 0.576, 95% CI 0.415-0.801). Disability was associated with mortality, cardiovascular mortality, and the composite at 30 days, and renal failure with mortality and major bleeding. CONCLUSIONS: Comorbidities like renal failure, long AF duration and disability were related to adverse outcomes and should be decisive to guide management decisions in ED patients with AF. Anticoagulation had a positive impact on prognosis and should be the mainstay of therapy in AF patients attended in ED.

Association between acute heart failure and major cardiovascular events in atrial fibrillation patients presenting at the emergency department: an EMERG-AF ancillary study.

BACKGROUND: There is little evidence concerning the impact of acute heart failure (AHF) on the prognosis of atrial fibrillation patients attending the emergency department (ED). OBJECTIVE: To know the influence of AHF on adverse long-term outcomes in patients presenting with atrial fibrillation in ED. DESIGN, SETTING AND PARTICIPANTS: Secondary analysis of a prospective, multicenter, observational cohort of consecutive atrial fibrillation patients, performed in 62 Spanish EDs. EXPOSURE: Patients presenting with atrial fibrillation in ED were divided by the presence or absence of AHF at arrival. OUTCOME MEASURES AND ANALYSIS: Primary outcome: combination of 1-year all-cause mortality, major bleeding, stroke and other major cardiovascular events (MACE). Secondary outcomes: each of these events analyzed separately. Cox and logistic regression were used to investigate adjusted significant associations between AHF and outcomes. MAIN RESULTS: Totally, 1107 consecutive ED patients with atrial fibrillation attending ED were analyzed, 262 (23.7%) with AHF. The primary outcome occurred in 433 patients (39.1%), 1-year all-cause mortality in 151 patients (13.6%), major bleeding in 47 patients (4.2 %), stroke in 31 patients (2.8 %) and other MACE in 333 patients (30.1%). AHF was independently related to the primary outcome [odds ratio (OR), 1.422; 95% confidence interval (CI), 1.020-1.981; P = 0.037)] and 1-year MACE (OR, 1.797; 95% CI, 1.285-2.512; P = 0.001), but not to 1-year all-cause mortality, stroke or bleeding. CONCLUSIONS: The coexistence of AHF in patients presenting with atrial fibrillation in ED is associated to a worse 1-year outcome mainly due to MACE, but does not impact in overall mortality.

Cardioversión en la fibrilación auricular de reciente comienzo / Cardioversion in recent onset atrial fibrillation

Objetivos: Este estudio analiza el control del ritmo en los servicios de urgencias (SUH) y sus resultados en pacientes con fibrilación auricular (FA) de reciente comienzo, para identificar áreas de mejora en el manejo. Método: Estudio multicéntrico, observacional, prospectivo y transversal desarrollado en 124 SUH representativos del sistema sanitario español basado en el registro HERMES-AF (estrategias de manejo en el servicio de urgencias hospitalario de la FA) del 23 de mayo al 5 de junio de 2011. Se incluyeron pacientes con FA sintomática con menos de 48 h de evolución en los cuales se tomó la decisión de restaurar el ritmo sinusal. Resultados: Se incluyeron 337 pacientes, se optó por cardioversión farmacológica en 311 pacientes (92,3%), y por cardioversión eléctrica en 52 (15%), la mitad de los casos tras fracaso de los fármacos. Se obtuvo ritmo sinusal (RS) en 278 pacientes (82,5%) y el alivio de los síntomas en 297 (94%), con una tasa de efectos adversos del 0,9%, ninguno grave. Amiodarona se asoció de manera independiente a una menor tasa de RS al alta (OR = 0,442; IC 95% 0,238-0,823; p = 0,01), al contrario que la cardioversión eléctrica (OR = 4,0; IC 95% 1,2-13,3; p = 0,024). Los fármacos I-C se asociaron con una mayor proporción de altas en < 6 h (OR 2,6; IC 95% 1,6-4,3; p < 0,001) y amiodarona con más estancias prolongadas de > 24 h (OR 2,7, IC 95% 1,5-4,8; p < 0,003). Conclusiones: En los SUH, la restauración del RS en la FA de reciente comienzo es segura, efectiva y asocia beneficios clínicos para los pacientes. Reemplazar amiodarona por técnicas más efectivas y rápidas como la cardioversión eléctrica o los fármacos I-C es un área de mejora de la calidad asistencial

Objectives: To analyze heart rate control in hospital emergency departments and outcomes in patients with recent onset atrial fibrillation (AF) so that targets for improvement can be identified. Methods: Multicenter, prospective observational cross-sectional study in a representative sample of 124 hospitals of the Spanish health services, based on records in the HERMES-AF database (Hospital Emergency Department Management Strategies for AF) for May 23 to June 5, 2011. Patients with symptomatic AF within 48 hours of onset were enrolled when the decision was made to attempt restoration of sinus rhythm. Results: We included 337 patients. Chemical cardioversion was used in 311 (92.3%) and electrical cardioversion in 52 (15%), after drugs had failed in half the cases. Sinus rhythm was restored in 278 patients (82.5%), and symptoms resolved in 94%. Adverse effects were recorded in 0.9% but none were serious. Amiodarone was independently associated with a lower rate of restored sinus rhythm (odds ratio [OR], 0.442; 95% CI, 0.238-0.823; P=.01) than electrical cardioversion (OR, 4.0; 95% CI, 1.2-13.3; P=.024). The use of class Ic antiarrhythmic agents was associated with a higher percentage of discharges in less than 6 hours (OR, 2.6; 95% CI, 1.6-4.3; P<.001), and amiodarone was associated with hospital stays longer than 24 hours (OR, 2.7; 95% CI, 1.5-4.8; P<.003). Conclusions: Emergency department restoration of sinus rhythm in patients with AF is safe, effective, and associated with clinical benefits. Quality of care could be improved by replacing the use of amiodarone with faster and more effective treatments such as electrical cardioversion or the use of class Ic agents

Cardioversion in recent onset atrial fibrillation. / Cardioversión en la fibrilación auricular de reciente comienzo.

OBJECTIVES: To analyze heart rate control in hospital emergency departments and outcomes in patients with recent onset atrial fibrillation (AF) so that targets for improvement can be identified. MATERIAL AND METHODS: Multicenter, prospective observational cross-sectional study in a representative sample of 124 hospitals of the Spanish health services, based on records in the HERMES-AF database (Hospital Emergency Department Management Strategies for AF) for May 23 to June 5, 2011. Patients with symptomatic AF within 48 hours of onset were enrolled when the decision was made to attempt restoration of sinus rhythm. RESULTS: We included 337 patients. Chemical cardioversion was used in 311 (92.3%) and electrical cardioversion in 52 (15%), after drugs had failed in half the cases. Sinus rhythm was restored in 278 patients (82.5%), and symptoms resolved in 94%. Adverse effects were recorded in 0.9% but none were serious. Amiodarone was independently associated with a lower rate of restored sinus rhythm (odds ratio [OR], 0.442; 95% CI, 0.238-0.823; P=.01) than electrical cardioversion (OR, 4.0; 95% CI, 1.2-13.3; P=.024). The use of class Ic antiarrhythmic agents was associated with a higher percentage of discharges in less than 6 hours (OR, 2.6; 95% CI, 1.6-4.3; P< .001), and amiodarone was associated with hospital stays longer than 24 hours (OR, 2.7; 95% CI, 1.5-4.8; P< .003). CONCLUSION: Emergency department restoration of sinus rhythm in patients with AF is safe, effective, and associated with clinical benefits. Quality of care could be improved by replacing the use of amiodarone with faster and more effective treatments such as electrical cardioversion or the use of class Ic agents.

OBJETIVO: Este estudio analiza el control del ritmo en los servicios de urgencias (SUH) y sus resultados en pacientes con fibrilación auricular (FA) de reciente comienzo, para identificar áreas de mejora en el manejo. METODO: Estudio multicéntrico, observacional, prospectivo y transversal desarrollado en 124 SUH representativos del sistema sanitario español basado en el registro HERMES-AF (estrategias de manejo en el servicio de urgencias hospitalario de la FA) del 23 de mayo al 5 de junio de 2011. Se incluyeron pacientes con FA sintomática con menos de 48 h de evolución en los cuales se tomó la decisión de restaurar el ritmo sinusal. RESULTADOS: Se incluyeron 337 pacientes, se optó por cardioversión farmacológica en 311 pacientes (92,3%), y por cardioversión eléctrica en 52 (15%), la mitad de los casos tras fracaso de los fármacos. Se obtuvo ritmo sinusal (RS) en 278 pacientes (82,5%) y el alivio de los síntomas en 297 (94%), con una tasa de efectos adversos del 0,9%, ninguno grave. Amiodarona se asoció de manera independiente a una menor tasa de RS al alta (OR = 0,442; IC 95% 0,238-0,823; p = 0,01), al contrario que la cardioversión eléctrica (OR = 4,0; IC 95% 1,2-13,3; p = 0,024). Los fármacos I-C se asociaron con una mayor proporción de altas en < 6 h (OR 2,6; IC 95% 1,6-4,3; p < 0,001) y amiodarona con más estancias prolongadas de > 24 h (OR 2,7, IC 95% 1,5-4,8; p < 0,003). CONCLUSIONES: En los SUH, la restauración del RS en la FA de reciente comienzo es segura, efectiva y asocia beneficios clínicos para los pacientes. Reemplazar amiodarona por técnicas más efectivas y rápidas como la cardioversión eléctrica o los fármacos I-C es un área de mejora de la calidad asistencial.

Benefits of Rhythm Control and Rate Control in Recent-onset Atrial Fibrillation: The HERMES-AF Study.

BACKGROUND: Although rhythm control has failed to demonstrate long-term benefits over rate control in longstanding episodes of atrial fibrillation (AF), there is little evidence concerning recent-onset ones. We analyzed the benefits of rhythm and rate control in terms of symptoms alleviation and need for hospital admission in patients with recent-onset AF. METHODS: This was a multicenter, observational, cross-sectional study with prospective standardized data collection carried out in 124 emergency departments (EDs). Clinical variables, treatment effectiveness, and outcomes (control of symptoms, final disposition) were analyzed in stable patients with recent-onset AF consulting for AF-related symptoms. RESULTS: Of 421 patients included, rhythm control was chosen in 352 patients (83.6%), a global effectiveness of 84%. Rate control was performed in 69 patients (16.4%) and was achieved in 67 (97%) of them. Control of symptoms was achieved in 396 (94.1%) patients and was associated with a heart rate after treatment ≤ 110 beats/min (odds ratio [OR] = 14.346, 95% confidence interval [CI] = 3.90 to 52.70, p < 0.001) and a rhythm control strategy (OR = 2.78, 95% CI = 1.02 to 7.61, p = 0.046). Sixty patients (14.2%) were admitted: discharge was associated with a rhythm control strategy (OR = 2.22, 95% CI = 1.20-4.60, p = 0.031) and admission was associated with a heart rate > 110 beats/min after treatment (OR = 29.71, 95% CI = 7.19 to 123.07, p < 0.001) and acute heart failure (OR = 9.45, 95% CI = 2.91 to 30.65, p < 0.001). CONCLUSION: In our study, recent-onset AF patients in whom rhythm control was attempted in the ED had a high rate of symptoms' alleviation and a reduced rate of hospital admissions.

Benefits of Emergency Departments' Contribution to Stroke Prophylaxis in Atrial Fibrillation: The EMERG-AF Study (Emergency Department Stroke Prophylaxis and Guidelines Implementation in Atrial Fibrillation).

BACKGROUND AND PURPOSE: Long-term benefits of initiating stroke prophylaxis in the emergency department (ED) are unknown. We analyzed the long-term safety and benefits of ED prescription of anticoagulation in atrial fibrillation patients. METHODS: Prospective, multicenter, observational cohort of consecutive atrial fibrillation patients was performed in 62 Spanish EDs. Clinical variables and thromboprophylaxis prescribed at discharge were collected at inclusion. Follow-up at 1 year post-discharge included data about thromboprophylaxis and its complications, major bleeding, and death; risk was assessed with univariate and bivariate logistic regression models. RESULTS: We enrolled 1162 patients, 1024 (88.1%) at high risk according to CHA2DS2-VASc score. At ED discharge, 935 patients (80.5%) were receiving anticoagulant therapy, de novo in 237 patients (55.2% of 429 not previously treated). At 1 year, 48 (4.1%) patients presented major bleeding events, and 151 (12.9%) had died. Anticoagulation first prescribed in the ED was not related to major bleeding (hazard ratio, 0.976; 95% confidence interval, 0.294-3.236) and was associated with a decrease in mortality (hazard ratio, 0.398; 95% confidence interval, 0.231-0.686). Adjusting by the main clinical and sociodemographic characteristics, concomitant antiplatelet treatment, or destination (discharge or admission) did not affect the results. CONCLUSIONS: Prescription of anticoagulation in the ED does not increase bleeding risk in atrial fibrillation patients at high risk of stroke and contributes to decreased mortality.

Stroke prophylaxis in atrial fibrillation: searching for management improvement opportunities in the emergency department: the HERMES-AF study.

STUDY OBJECTIVE: We determine the prevalence of stroke prophylaxis prescription in emergency department (ED) patients with atrial fibrillation and the factors associated with a lack of prescription of anticoagulation in high-risk patients without contraindications. METHODS: This was a multicenter, observational, cross-sectional study with prospective standardized data collection carried out in 124 Spanish EDs. Clinical variables, risk factors for stroke, type of prophylaxis prescribed, and reasons for not prescribing anticoagulation in high-risk patients (congestive heart failure/left ventricular dysfunction, hypertension, age >75 years, diabetes and previous stroke/transient ischemic attack/systemic embolism [CHADS2] score ≥2 and the congestive heart failure/left ventricular dysfunction, hypertension, age >75 years, diabetes, previous stroke/transient ischemic attack/systemic embolism, vascular disease age 65 to 74 years and sex category [CHA2DS2-VASc] score ≥2) without contraindications were collected. RESULTS: Of 3,276 patients enrolled, 71.5% were at high risk according to CHADS2; 89.7% according to CHA2DS2-VASc. At discharge from the ED, 2,255 patients (68.8%) were receiving anticoagulants, 1,691 of whom (75%) were high-risk patients. Of the 1,931 patients discharged home, anticoagulation was prescribed for 384 patients (19.9%) de novo and for 932 patients (48.3%) previously receiving anticoagulation. The main reasons for not prescribing anticoagulation to eligible patients were considering antiplatelet therapy as adequate prophylaxis (33.1%), advanced age (15%), and considering stroke risk as low (8.3%). Advanced age (odds ratio 0.46; 95% confidence interval 0.30 to 0.69) and female sex (odds ratio 0.50; 95% confidence interval 0.36 to 0.71) were significantly associated with the lack of prescription of anticoagulation to eligible patients. CONCLUSION: In Spain, most patients with atrial fibrillation treated in EDs who do not receive anticoagulation are at high risk of stroke, with relevant differences with regard to the risk stratification scheme used. Anticoagulation is underused, mainly because the risk of stroke is underestimated by the treating physicians and the benefits of antiplatelets are overrated, principally in female patients and the elderly. Efforts to increase the prescription of anticoagulation in these patients appear warranted.

Analysis of the characteristics of interconsultations performed by emergency physicians to other hospital specialists and their evolution over time.

OBJECTIVE: The objective of this study was to describe the type of interconsultations carried out in the Emergency Department (ED) to hospital specialists and analyze their pattern over time. METHODS: The study was carried out during the period from 2006 to 2012. It was carried out at EDs attending to all types of interconsultations except pediatrics and obstetrics-gynecology. There were no changes in physical structure, number of personnel, or organization during the study period. The main measurements taken were as follows: monthly ED census, number of interconsultations and specialties consulted, main reason for presentation at the ED during the first (2006) and last year (2012), and, for specialties demonstrating substantial quantitative changes, main reasons for the interconsultation from the ED at the beginning (2006) and the end (2012) of the study. Linear regression analysis was carried out for the relationship between time and number of interconsultations. RESULTS: A total of 628 256 care interventions were carried out, with 128 008 interconsultations (20.4%). Orthopedic surgery and traumatology, psychiatry, and general and digestive surgery were the departments most frequently consulted (54.5% of the interconsultations). Consultations significantly reduced over time (R=0.29; P<0.001) but the percentage of interconsultations (related to ED census) remained unchanged (R=0.01; P=0.49). The behavior related to specialties was heterogeneous: consultations to general and digestive surgery, hematology and hemostasis, and urology specialists decreased, whereas to thoracic surgery, angiology and vascular surgery, neurology, nephrology, neurosurgery, psychiatry, orthopedic surgery and traumatology, and critical care medicine specialists increased. Some of the reasons for specialist consultation also significantly changed over time. CONCLUSION: The study of interconsultations allows us to identify areas of lesser autonomy of emergency physicians. Changes in the pattern of these interconsultations over time may reflect both learning processes and changes in the healthcare circuits in the ED.
