Influencia de la renta económica en la mortalidad intrahospitalaria de las personas mayores durante la primera ola de la pandemia por COVID-19: resultados del estudio EDEN-33 / Influence of income on in-hospital mortality in older adults during the first wave of the COVID-19 pandemic: results from the EDEN-33 study

Objetivo: Determinar si el nivel económico durante la primera ola pandémica tuvo una influencia diferente a la esperable en la mortalidad intrahospitalaria de los pacientes mayores atendidos en los servicios de urgencias (SU) de los hospitales públicos españoles. Método: Cincuenta y un SU públicos españoles que participaron voluntariamente y que dan cobertura al 25% de la población incluyeron todos los registros de pacientes de edad $ 65 años atendidos durante una semana del periodo preCOVID (1-4-2019 a 7-4-2019) y una semana del periodo COVID (30-3-2020 a 5-4-2020). Se identificó la renta bruta (RB) asignada al código postal de residencia de cada paciente y se calculó la RB normalizada (RBN) dividiendo aquella por la RB media de su comunidad autónoma. La existencia y fuerza de la relación entre RBN y mortalidad intrahospitalaria se determinó mediante curvas spline cúbicas restringidas (SCR) ajustadas por 10 características basales del paciente. Las OR para cada situación económica se expresó en relación con una RBN de 1 (referencia, renta correspondiente a la media de la comunidad autónoma). La comparación entre periodo COVID y no COVID se realizó mediante el estudio de interacción de primer grado. (AU)

Objective: To determine whether income was associated with unexpected in-hospital mortality in older patients treated in Spanish public health system hospital emergency departments. Methods: Fifty-one public health system hospital emergency departments in Spain voluntarily participated in the study. Together the hospitals covered 25% of the population aged 65 years or older included in all patient registers during a week in the pre-pandemic period (April 1-7, 2019) and a week during the COVID-19 pandemic (March 30 to April 5, 2020). We estimated a patient’s gross income as the amount published for the postal code of the patient’s address. We then calculated the standardized gross income (SGI) by dividing the patient’s estimated income by the mean for the corresponding territory (Spanish autonomous community). The existence and strength of an association between the SGI and in-hospital mortality was evaluated by means of restricted cubic spline (RCS) curves adjusted for 10 patient characteristics at baseline. Odds ratios (ORs) for each income level were expressed in relation to a reference SGI of 1 (the mean income for the corresponding autonomous community). We compared the COVID-19 and pre-pandemic periods by means of first-order interactions. (AU)

Together the hospitals covered 25% of the population aged 65 years or older included in all patient registers during a week in the pre-pandemic period (April 1-7, 2019) and a week during the COVID-19 pandemic (March 30 to April 5, 2020). We estimated a patient's gross income as the amount published for the postal code of the patient's address. We then calculated the standardized gross income (SGI) by dividing the patient's estimated income by the mean for the corresponding territory (Spanish autonomous community). The existence and strength of an association between the SGI and in-hospital mortality was evaluated by means of restricted cubic spline (RCS) curves adjusted for 10 patient characteristics at baseline. Odds ratios (ORs) for each income level were expressed in relation to a reference SGI of 1 (the mean income for the corresponding autonomous community). We compared the COVID-19 and pre-pandemic periods by means of first-order interactions. RESULTS: Of the 35 280 patients attended in the 2 periods, gross income could be ascertained for 21 180 (60%), 15437 in the pre-pandemic period and 5746 during the COVID-19 period. SGIs were slightly higher for patients included before the pandemic (1.006 vs 0.994; P = .012). In-hospital mortality was 5.6% overall and higher during the pandemic (2.8% pre-pandemic vs 13.1% during COVID-19; P .001). The adjusted RCS curves showed that associations between income and mortality differed between the 2 periods (interaction P = .004). Whereas there were no significant income-influenced differences in mortality before the pandemic, mortality increased during the pandemic in the lowest-income population (SGI 0.5 OR, 1.82; 95% CI, 1.32-3.37) and in higher-income populations (SGI 1.5 OR, 1.32; 95% CI, 1.04-1.68, and SGI 2 OR, 1.92; 95% CI, 1.14-3.23). We found no significant differences between patients with COVID-19 and those with other diagnoses (interaction P = .667). CONCLUSION: The gross income of patients attended in Spanish public health system hospital emergency departments, estimated according to a patient's address and postal code, was associated with in-hospital mortality, which was higher for patients with the lowest and 2 higher income levels. The reasons for these associations might be different for each income level and should be investigated in the future.

Las OR para cada situación económica se expresó en relación con una RBN de 1 (referencia, renta correspondiente a la media de la comunidad autónoma). La comparación entre periodo COVID y no COVID se realizó mediante el estudio de interacción de primer grado. RESULTADOS: De los 35.280 registros de pacientes atendidos en ambos periodos, se disponía de la RB en 21.180 (60%): 15.437 del periodo preCOVID y 5.746 del periodo COVID. La RBN de los pacientes incluidos fue discretamente superior en el periodo preCOVID (1,006 versus 0,994; p = 0,012). La mortalidad intrahospitalaria fue del 5,6%, y fue superior durante el periodo COVID (2,8% versus 13,1%; p 0,001). Las curvas SCR ajustadas mostraron una asociación entre nivel económico y mortalidad diferente entre ambos periodos (p interacción = 0,004): en el periodo preCOVID no hubo diferencias significativas de mortalidad en función de la RBN, mientras que en el periodo COVID la mortalidad se incrementó en rentas bajas (OR = 1,82, IC 95% = 1,32-3,37 para RBN de 0,5) y en rentas altas (OR = 1,32, IC 95% = 1,04-1,68 y OR = 1,92, IC 95% = 1,14-3,23 para RBN de 1,5 y 2, respectivamente), sin diferencias significativas entre pacientes con COVID y con otros diagnósticos (p interacción = 0,667). CONCLUSIONES: Durante la primera ola de la pandemia COVID, la RB asignada al código postal de residencia de los pacientes atendidos en los SU públicos españoles se asoció con la mortalidad intrahospitalaria, que aumentó en pacientes de rentas bajas y altas. Las razones de estas asociaciones pueden ser distintas para cada segmento económico y deben ser investigadas en el fututo.

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.

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.
