Use of diagnostic tests in elderly patients consulting the emergency department. Analysis of the emergency department and elder needs cohort (EDEN-8).

OBJECTIVE: Analyse the association between the use of diagnostic tests and the characteristics of older patients 65 years of age or more who consult the emergency department (ED). METHODS: We performed an analysis of the EDEN cohort that includes patients who consulted 52 Spanish EDs. The association of age, sex, and ageing characteristics with the use of diagnostic tests (blood tests, electrocardiogram (ECG), microbiological cultures, X-ray, computed tomography, ultrasound, invasive techniques) was studied. The association was analysed by calculating the adjusted odds ratios (aOR) and their 95 % confidence intervals (CI) using a logistic regression model. RESULTS: A total of 25,557 patients were analysed. There was an increase in the use of diagnostic tests based on age, with an aOR for blood test of 1.805 (95 %CI 1.671 - 1.950), ECG 1.793 (95 %CI 1.664 - 1.932) and X-ray 1.707 (95 %CI 1.583 - 1.840) in the group of 85 years or more. The use of diagnostic tests is lower in the female population. Most ageing characteristics (cognitive impairment, previous falls, polypharmacy, dependence, and comorbidity) were independently associated with increased use of diagnostic tests. CONCLUSIONS: Age, and the characteristics of ageing itself are generally associated with a greater use of diagnostic tests in the ED.

Use of resources in elderly patients consulting the emergency department: analysis of the Emergency Department and Elder Needs Cohort (EDEN-21).

The elderly population frequently consults the emergency department (ED). This population could have greater use of EDs and hospital health resources. The EDEN cohort of patients aged 65 years or older visiting the ED allowed this association to be investigated. To analyse the association between healthcare resource use and the characteristics of patients over 65 years of age who consult hospital EDs. We performed an analysis of the EDEN cohort, a retrospective, analytical, and multipurpose registry that includes patients over 65 years of age who consulted in 52 Spanish EDs. The impact of age, sex, and characteristics of ageing on the following outcomes was studied: need for hospital admission (primary outcome) and need for observation, stay in the ED > 12 h, prolonged hospital stay > 7 days, need for intensive care unit (ICU) and return to the ED at 30 days related to the index visit (secondary outcomes). The association was analysed by calculating the adjusted odds ratios (aOR) and their 95% confidence intervals (CI), using a logistic regression model. A total of 25,557 patients with a mean age of 78.3 years were analysed, 45% were males. Of note was the presence of comorbidity, a Charlson index ≥ 3 (33%), and polypharmacy (66%). Observation in the ED was required by 26%, 25.4% were admitted to the hospital, and 0.9% were admitted to the ICU. The ED stay was > 12 h in 12.5% and hospital stay > 7 days in 13.5% of cases. There was a progressive increase in healthcare resource use based on age, with an aOR for the need for observation of 2.189 (95% CI 2.038-2.352), ED stay > 12 h 2.136 (95% CI 1.942-2.349) and hospital admission 2.579 (95% CI 2.399-2.772) in the group ≥ 85 years old. Most of the characteristics inherent to ageing (cognitive impairment, falls in the previous 6 months, polypharmacy, functional dependence, and comorbidity) were associated with significant increases in the use of healthcare resources, except for ICU admission, which was less in all the variables studied. Age and the characteristics inherent to ageing are associated with greater use of structural healthcare resources.

Impact of dementia on 30-, 180-, and 365-day mortality during the first pandemic wave in older adults seen in spanish emergency departments diagnosed with or without COVID-19.

OBJECTIVES: To assess whether dementia is an independent predictor of death after a hospital emergency department (ED) visit by older adults with or without a COVID-19 diagnosis during the first pandemic wave. METHOD: We used data from the EDEN-Covid (Emergency Department and Elderly Needs during Covid) cohort formed by all patients ≥65 years seen in 52 Spanish EDs from March 30 to April 5, 2020. The association of prior history of dementia with mortality at 30, 180 and 365 d was evaluated in the overall sample and according to a COVID-19 or non COVID diagnosis. RESULTS: We included 9,770 patients aged 78.7 ± 8.3 years, 51.1% men, 1513 (15.5%) subjects with prior history of dementia and 3055 (31.3%) with COVID-19 diagnosis. 1399 patients (14.3%) died at 30 d, 2008 (20.6%) at 180 days and 2456 (25.1%) at 365 d. The adjusted Hazard Ratio (aHR) for age, sex, comorbidity, disability and diagnosis for death associated with dementia were 1.16 (95% CI 1.01-1.34) at 30 d; 1.15 at 180 d (95% CI 1.03-1.30) and 1.19 at 365 d (95% CI 1.07-1.32), p < .001. In patients with COVID-19, the aHR were 1.26 (95% CI: 1.04-1.52) at 30 days; 1.29 at 180 d (95% CI: 1.09-1.53) and 1.35 at 365 d (95% CI: 1.15-1.58). CONCLUSION: Dementia in older adults attending Spanish EDs during the first pandemic wave was independently associated with 30-, 180- and 365-day mortality. This impact was lower when adjusted for age, sex, comorbidity and disability, and was greater in patients diagnosed with COVID-19.

Predictive usefulness of qSOFA, NEWS and GYM scores in the elderly patient: EDEN-5 study.

OBJECTIVE: To analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease. METHODS: Data from the EDEN (Emergency Department and Elderly Need) cohort were used. This retrospective cohort included all patients aged ≥65 years seen in 52 Spanish EDs during two weeks (from 1-4-2019 to 7-4-2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality. RESULTS: 6054 patients were analyzed. Median age was 80 years (IQR 73-87) and 45.3% women. 993 (16,4%) patients died. NEWS score had better AUC than qSOFA (0.765, 95CI: 0.725-0.806, versus 0.700, 95%CI: 0.653-0.746; P < .001) and GYM (0.716, 95%CI: 0.675-0.758; P = .024), and there was no difference between qSOFA and GYM (P = .345). The highest sensitivity scores for 30-day mortality were GYM ≥ 1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWS ≥ 8 showed high specificity. CONCLUSION: NEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity.

[Impacto de la dependencia funcional de los pacientes mayores atendidos en los servicios de Urgencias españoles durante la primera ola pandémica de la COVID-19 sobre la mortalidad a 30, 180 y 365 días en función del diagnóstico (COVID versus no COVID).] / Impact of functional dependency of elderly patients seen in Spanish emergency departments during the first wave of the COVID-19 pandemic on mortality at 30, 180 and 365 days depending on the diagnosis (COVID versus non-COVID).

OBJECTIVE: Functional assessment is part of geriatric assessment. How it is performed in hospital Emergency Departments (ED) is poorly understood, let alone its prognostic value. The aim of this paper was to investigate whether baseline disability to perform basic activities of daily living (BADL) was an independent prognostic factor for death after the index visit to the ED during the first wave of the COVID-19 pandemic and whether it had a different impact on patients with and without diagnosis of COVID-19. METHODS: A retrospective observational study of the EDEN-Covid (Emergency Department and Elder Needs during COVID) cohort was carried out, consisting of all patients aged ≥65 years seen in 52 Spanish EDs selected by chance during 7 consecutive days (30/3/2020 to 5/4/2020). Demographic, clinical, functional, mental and social variables were analyzed. Dependence was categorized with the Barthel index (BI) as independent (BI=100), mild-moderate dependence (100>BI>60) and severe-total dependence (BI<60), and their crude and adjusted association was evaluated with mortality at 30, 180 and 365 days using COX proportional hazards models. RESULTS: Of 9,770 enrolled patients with a mean age of 79 years, 51% were men, 6,305 (64.53%) were independent, 2,340 (24%) had mild-moderate dependence, and 1,125 (11.5%) severe-total dependence. The number of deaths at 30 days in these three groups was 500 (7.9%), 521 (22.3%) and 378 (33.6%), respectively; at 180 days it was 757 (12%), 725 (30.9%) and 526 (46.8%); and at 365 days 954 (15.1%), 891 (38.1%) and 611 (54.3%). In relation to independent patients, the adjusted risks (hazard ratio) of dying within 30 days associated with mild-moderate and severe-total dependency were 1.91 (95% CI: 1.66-2.19) and 2.51. (2.11-2.98); at 180 days they were 1.88 (1.68-2.11) and 2.64 (2.28-3.05); and at 365 days they were 1.82 (1.64-2.02) and 2.47 (2.17-2.82). This negative impact of dependency on mortality was greater in patients diagnosed with COVID-19 than in non-COVID-19 (p interaction at 30, 180 and 365 days of 0.36, 0.05 and 0.04). CONCLUSIONS: The functional dependence of older patients who attend Spanish EDs during the first wave of the pandemic is associated with mortality at 30, 180 and 365 days, and this risk is significantly higher in patients treated for COVID-19.

OBJETIVO: La valoración funcional forma parte de la valoración geriátrica. No se conoce bien cómo se realiza en los servicios de Urgencias hospitalarios (SUH) y menos aún su valor pronóstico. El objetivo de este trabajo fue investigar si la dependencia funcional basal para realizar las actividades básicas de la vida diaria (ABVD) era un factor pronóstico independiente de muerte tras la visita índice al SUH durante la primera ola pandémica de la COVID-19 y si tuvo un impacto diferente en pacientes con y sin diagnóstico de COVID-19. METODOS: Se realizó un estudio observacional retrospectivo de la cohorte EDEN-Covid (Emergency Department and Elder Needs during COVID) formada por todos los pacientes de edad mayor o igual a 65 años atendidos en 52 SUH españoles, seleccionados por oportunidad durante siete días consecutivos (del 30 de marzo al 5 de abril de 2020). Se analizaron variables demográficas, clínicas, funcionales, mentales y sociales. La dependencia se categorizó con el índice de Barthel (IB) en independiente (IB=100), dependencia leve-moderada (100>IB>60) y dependencia grave-total (IB<60), y se evaluó su asociación cruda y ajustada con la mortalidad a 30, 180 y 365 días mediante modelos de riesgos proporcionales de COX. RESULTADOS: De 9.770 pacientes incluidos con una media de edad de 79 años, un 51% eran hombres, 6.305 (64,53%) eran independientes, 2.340 (24%) tenían dependencia leve-moderada y 1.125 (11,5%) dependencia grave-total. El número de fallecidos a 30 días en estos tres grupos fue 500 (7,9%), 521 (22,3%) y 378 (33,6%), respectivamente; a 180 días fue 757 (12%), 725 (30,9%) y 526 (46,8%); y a 365 días 954 (15,1%), 891 (38,1%) y 611 (54,3%). En relación a los pacientes independientes, los riesgos (hazard ratio) ajustados de fallecer a 30 días, asociados a dependencia leve-moderada y grave-total, fueron 1,91 (IC 95%: 1,66-2,19) y 2,51 (2,11-2,98); a 180 días fueron de 1,88 (1,68-2,11) y 2,64 (2,28-3,05); y a 365 días fueron 1,82 (1,64-2,02) y 2,47 (2,17-2,82). Este impacto negativo de la dependencia sobre la mortalidad fue mayor en pacientes diagnosticados de COVID-19 que en los no COVID-19 (p interacción a 30, 180 y 365 días de 0,36, 0,05 y 0,04). CONCLUSIONES: La dependencia funcional de los pacientes mayores que acuden a SUH españoles durante la primera ola pandémica se asocia a mortalidad a 30, 180 y 365 días, y este riesgo es significativamente mayor en los pacientes atendidos por COVID-19.

Influence of type of household on prognosis at one year in patients ≥65 years attending hospital emergency departments in Spain. The EDEN-6 study.

OBJECTIVE: To investigate whether the type of household is associated with prognosis at one year in patients ≥65 years of age discharged after medical consultation requiring emergency department care. METHODS: Data from the Emergency Department and Elder Needs (EDEN) cohort were used. This retrospective cohort included all patients ≥65 years of age seen in 52 Spanish emergency departments over one week (April 1-7, 2019) in whom the type of household was recorded and categorized as living at home alone, with relatives, with professional caregivers, or in a nursing home. Patient demographic and other baseline characteristics and management during the index emergency department episode were recorded and used to adjust the following 1-year outcomes: all-cause mortality, hospitalization and emergency department revisit. Associations between type of household and outcomes are expressed as adjusted hazard ratios with 95% confidence intervals using living alone as the reference category. RESULTS: 13,442 patients with a median age of 79 years (interquartile range 72-86) were included; 56% were women, 12.2% of patients lived alone, 74.9% with relatives, 3.9% with a professional caregiver, and 9.1% in a nursing home. During the year following discharge, the mortality rate was 14.0%, the hospitalization rate 29.7%, and the emergency department revisit rate 59.3%. In the fully adjusted model, the risk of death was associated only with living in a nursing home (hazard ratio 1.366 (1.101-1.695)). On the other hand, the risk of hospitalization was lower in individuals living in nursing homes (hazard ratio 0.783 [0.676-0.907]) and at home with relatives (hazard ratio 0.897 [0.810-0.992]), while the risk of emergency department revisit was lower in individuals living in nursing homes (hazard ratio 0.826 [0.742-0.920]) or at home with caregivers (hazard ratio 0.856 [0.750-0.976]). CONCLUSION: The type of household was modestly associated with the one-year prognosis of patients ≥65 years of age discharged after attendance at an emergency department. Living in a nursing home is associated with an increased risk of death but a decreased risk of rehospitalization or emergency department revisit, while living at home with relatives or professional caregivers is associated only with a decreased risk of hospitalization and emergency department revisit, respectively.

Impact of the COVID-19 pandemic on demand for emergency department care for older patients: the EDEN-7 COVID cohort study. / Estudio EDEN-7: impacto de la pandemia COVID-19 sobre la demanda asistencial de personas mayores en los servicios de urgencias españoles.

OBJECTIVES: To analyze the impact of the COVID-19 pandemic on Spanish emergency department (ED) care for patients aged 65 years or older during the first wave vs. a pre-pandemic period. MATERIAL AND METHODS: Retrospective cross-sectional study of a COVID-19 portion of the EDEN project (Emergency Department and Elder Needs). The EDEN-COVID cohort included all patients aged 65 years or more who were treated in 52 EDs on 7 consecutive days early in the pandemic. We analyzed care variables, discharge diagnoses, use of diagnostic and therapeutic resources, use of observation units, need for hospitalization, rehospitalization, and mortality. These data were compared with data for an EDEN cohort in the same age group recruited during a similar period the year before the pandemic. RESULTS: The 52 participating hospital EDs attended 33 711 emergencies during the pandemic vs. 96 173 emergencies in the pre-COVID period, representing a 61.7% reduction during the pandemic. Patients aged 65 years or older accounted for 28.8% of the caseload during the COVID-19 period and 26.4% of the earlier cohort (P .001). The COVID-19 caseload included more men (51.0%). Comorbidity and polypharmacy were more prevalent in the pandemic cohort than in the earlier one (comorbidity, 92.6% vs. 91.6%; polypharmacy, 65.2% vs. 63.6%). More esturesources (analgesics, antibiotics, heparins, bronchodilators, and corticosteroids) were applied in the pandemic period, and common diagnoses were made less often. Observation wards were used more often (for 37.8% vs. 26.2% in the earlier period), and hospital admissions were more frequent (in 56.0% vs. 25.3% before the pandemic). Mortality was higher during the pandemic than in the earlier cohort either in ED (1.8% vs 0.5%) and during hospitalization (11.5 vs 2.9%). CONCLUSION: The proportion of patients aged 65 years or older decreased in the participating Spanish EDs. However, more resources were required and the pattern of diagnoses changed. Observation ward stays were longer, and admissions and mortality increased over the numbers seen in the reference period.

OBJETIVO: Analizar el impacto de la pandemia COVID-19 sobre la asistencia a las personas mayores ($ 65 años) en los servicios de urgencias hospitalarios (SUH) españoles durante la primera oleada pandémica, comparándola con un periodo previo. METODO: Estudio transversal retrospectivo de la cohorte EDEN-COVID (Emergency Department and Elder Needs during COVID), que incluyó a todos los pacientes $ 65 años atendidos en 52 SUH españoles durante 7 días consecutivos de un periodo pandémico. Se analizaron variables asistenciales, diagnósticos de alta, consumo de recursos diagnósticos y terapéuticos, utilización de las unidades de observación, necesidad de ingreso, rehospitalización y mortalidad. Estos datos se compararon con la cohorte EDEN (Emergency Department and Elder Needs), que reclutó a pacientes del mismogrupo de edad durante un periodo similar del año anterior. RESULTADOS: Durante el periodo COVID-19 se atendieron 33.711 episodios en los 52 SUH participantes, frente a 96.173 del periodo pre-COVID, lo que supone una disminución de la demanda de 61,7%. La proporción de asistencias a pacientes de 65 o más años fue de 28,8% en el periodo COVID-19 y 26,4% en el periodo previo (p 0,001). Durante el periodo COVID hubo mayor proporción de hombres (51,0% vs 44,9%), mayor comorbilidad (92,6% vs 91,6%) y polifarmacia (65,2% vs 63,6%), mayor uso de recursos, de analgésicos, antibióticos, heparinas, broncodilatadores y corticoides, menor proporción de los diagnósticos más habituales, mayor utilización de las unidades de observación (37,8% vs 26,2%) y un incremento de la proporción de ingresos (56,0% vs 25,3%), y de mortalidad en urgencias (1,8% vs 0,5%) y durante la hospitalización (11,5% vs 2,9%). CONCLUSIONES: La primera ola de la pandemia COVID-19 ha provocado una disminución global de las asistencias a personas mayores ($ 65 años) en los SUH españoles analizados, mayor consumo de recursos, un mapa diferente de procesos diagnósticos asistidos y un aumento proporcional de estancias en observación, de ingresos y de mortalidad, respecto al periodo de referencia.

Study EDEN-12: Analysis of access to intensive care units of patients older than 65 years requiring emergency hospitalization.

OBJECTIVE: To investigate the relationship between the age of an urgently hospitalized patient and his or her probability of admission to an intensive care unit (ICU). DESIGN: Observational, retrospective, multicenter study. SETTING: 42 Emergency Departments from Spain. TIME-PERIOD: April 1-7, 2019. PATIENTS: Patients aged ≥65 years hospitalized from Spanish emergency departments. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: ICU admission, age sex, comorbidity, functional dependence and cognitive impairment. RESULTS: 6120 patients were analyzed (median age: 76 years; males: 52%. 309 (5%) were admitted to ICU (186 from ED, 123 from hospitalization). Patients admitted to the ICU were younger, male, and with less comorbidity, dependence and cognitive impairment, but there were no differences between those admitted from the ED and from hospitalization. The OR for ICU-admission adjusted by sex, comorbidity, dependence and dementia reached statistical significance >83 years (OR: 0.67; 95%CI: 0.45-0.49). In patients admitted to the ICU from ED, the OR did not begin to decrease until 79 years, and was significant >85 years (OR: 0.56, 95%CI: 0.34-0.92); while in those admitted to ICU from hospitalization, the decrease began 65 years of age, and were significant from 85 years (OR: 0.55, 95%CI: 0.30-0.99). Sex, comorbidity, dependency and cognitive deterioration of the patient did not modify the association between age and ICU-admission (overall, from the ED or hospitalization). CONCLUSIONS: After taking into account other factors that influence admission to the ICU (comorbidity, dependence, dementia), the chances of admission to the ICU of older patients hospitalized on an emergency basis begin to decrease significantly after 83 years of age. There may be differences in the probability of admission to the ICU from the ED or from hospitalization according to age.

Quality of hospital emergency department care for patients with COVID-19 during the first wave in 2020: the CALUR-COVID-19 study. / Estudio CALUR-COVID-19: calidad asistencial en urgencias del proceso de atención a pacientes con COVID-19 durante el primer pico pandémico de 2020.

OBJECTIVES: To define quality of care indicators and care process standards for treating patients with COVID-19 in hospital emergency departments (EDs), to determine the level of adherence to standards during the first wave in 2020, and to detect factors associated with different levels of adherence. MATERIAL AND METHODS: We selected care indicators and standards by applying the Delphi method. We then analyzed the level of adherence in the SIESTA cohort (registered by the Spanish Investigators in Emergency Situations Team). This cohort was comprised of patients with COVID-19 treated in 62 Spanish hospitals in March and April 2020. Adherence was compared according to pandemic-related ED caseload pressure, time periods during the wave (earlier and later), and age groups. RESULTS: Fourteen quality indicators were identified. Three were adhered to in less than 50% of the patients. Polymerase chain reaction testing for SARS-CoV-2 infection was the indicator most often disregarded, in 29% of patients when the caseload was high vs 40% at other times (P .001) and in 30% of patients in the later period vs 37% in the earlier period (P = .04). Adherence to the following indicators was better in the later part of the wave: monitoring of oxygen saturation (100% vs 99%, P = .035), electrocardiogram monitoring in patients treated with hydroxychloroquine (87% vs 65%, P .001), and avoiding of lopinavir/ritonavir treatment in patients with diarrhea (79% vs 53%, P .001). No differences related to age groups were found. CONCLUSION: Adherence to certain quality indicators deteriorated during ED treatment of patients with COVID-19 during the first wave of the pandemic. Pressure from high caseloads may have exacerbated this deterioration. A learning effect led to improvement. No differences related to patient age were detected.

OBJETIVO: Definir indicadores de calidad y sus estándares para el proceso asistencial del paciente con COVID-19 en servicios de urgencias hospitalarios (SUH), así como determinar su grado de cumplimiento durante el primer pico pandémico e investigar si existieron diferencias en relación con diferentes factores. METODO: Siguiendo la metodología del Delphi, los autores seleccionaron los indicadores y sus estándares. Posteriormente, se analizó el grado de cumplimiento en la cohorte SIESTA, formada por pacientes COVID-19 de 62 SUH españoles atendidos en marzo y abril de 2020. Se comparó el cumplimiento de los indicadores según la presión asistencial generada por la pandemia en el SUH, el periodo asistencial y el grupo etario. RESULTADOS: Se definieron 14 indicadores. Tres de ellos se cumplieron en 50% de los pacientes. La realización de la reacción en cadena de la polimerasa (PCR) para el SARS-CoV-2 tuvo peor cumplimiento en SUH con alta presión (29% frente a 40%, p 0,001) y durante el periodo tardío (30% frente a 37%, p = 0,04). Durante el periodo tardío, mejoró la medida de saturación de oxígeno (100% frente a 99%, p = 0,035), la realización de electrocardiograma en pacientes tratados con hidroxicloroquina (87% frente a 65%, p 0,001) y la no administración de lopinavir-ritonavir en pacientes con diarrea (79% frente a 53%, p 0,001). No hubo diferencias en relación con el grupo etario. CONCLUSIONES: Durante el primer pico pandémico, diversos aspectos de la calidad de la atención a pacientes COVID-19 en los SUH españoles se vieron deteriorados. La presión asistencial pudo incrementar este deterioro. Hubo un efecto de aprendizaje que condicionó una mejora, pero no se observaron diferencias según la edad de los pacientes.

Ability of lactate, procalcitonin, and criteria defining sepsis to predict 30-day mortality, bacteremia, and microbiologically confirmed infection in patients with infection suspicion treated in emergency departments. / Capacidad del lactato, procalcitonina y de los criterios definitorios de sepsis para predecir mortalidad a 30 días, bacteriemia o infección confirmada microbiológicamente en los pacientes atendidos por sospecha de infección en urgencias.

OBJECTIVES: To evaluate lactate, procalcitonin, criteria defining systemic inflammatory response syndrome (SIRS), and the Quick Sepsis-Related Organ Failure Assessment (qSOFA) and compare their ability to predict 30-day mortality, infection with microbiologic confirmation, and true bacteremia in patients treated for infection in hospital emergency departments. MATERIAL AND METHODS: Prospective multicenter observational cohort study. We enrolled a convenience sample of patients aged 18 years or older attended in 71 Spanish emergency departments from October 1, 2019, to March 31, 2020. Each model's predictive power was analyzed with the area under the receiver operating characteristic curve (AUC), and predetermined decision points were assessed. RESULTS: A total of 4439 patients with a mean (SD) age of 18 years were studied; 2648 (59.7%) were men and 459 (10.3%) died within 30 days. True bacteremia was detected in 899 (20.25%), and microbiologic confirmation was on record for 2057 (46.3%). The model that included the qSOFA score (2) and lactate concentration (0.738 mmol/L; 95% CI, 0.711-0.765 mmol/L) proved to be the best predictor of 30-day mortality, with an AUC of 0.890 (95% CI, 0.880-0.901). The model that included the SIRS score (2) and procalcitonin concentration (0.51 ng/mL) proved to be the best predictor of true bacteremia and microbiologic confirmation, with an AUC of 0.713 (95% CI, 0.698-0.728). CONCLUSION: A qSOFA score of 2 or more plus lactate concentration (0.738 mmol/L) predict 30-day mortality better than the combination of a SIRS score of 2 or more and procalcitonin concentration. A SIRS score of 2 or more plus procalcitonin concentration (0.51 ng/mL) predict true bacteremia and microbiologic confirmation.

OBJETIVO: Evaluar y comparar la capacidad del lactato, la procalcitonina (PCT) y de los criterios definitorios de sepsis (síndrome de respuesta inflamatoria sistémica ­SRIS­ y del quick Sepsis-related Organ Failure Assessment ­qSOFA­) para predecir mortalidad a 30 días, o infección ­con confirmación microbiológica o bacteriemia verdadera (BV)­ en los pacientes que acuden al servicio de urgencias hospitalario (SUH) por un episodio de sospecha de infección. METODO: Estudio observacional de cohortes, multicéntrico, prospectivo. Se incluyó por oportunidad a pacientes 18 años atendidos por sospecha de infección en 71 SUH españoles desde el 01/10/2019 al 31/03/2020. Se analizó la capacidad predictiva con el área bajo la curva (ABC) de la característica operativa del receptor (COR) y puntos de decisión predeterminados. RESULTADOS: Se incluyeron 4.439 pacientes con edad media de 67 (18) años, 2.648 (59,7%) fueron hombres, fallecieron a los 30 días 459 (10,3%), se consideraron BV 899 (20,2%) y se consiguió confirmación microbiológica en 2.057 (46,3%). Para la mortalidad a 30 días la mejor ABC-COR fue la obtenida con el modelo qSOFA 2 más lactato 2 mmol/l con un ABC-COR de 0,738 (0,711-0,765). Para predecir BV y confirmación microbiológica el mejor rendimiento se obtuvo con el modelo de SRIS 2 más PCT 0,51 ng/ml, con un ABC-COR de 0,890 (0,880-0,901) y 0,713 (0,698-0,728), respectivamente. CONCLUSIONES: Para la predicción de mortalidad a 30 días, el qSOFA 2 es superior al SRIS 2 y el mejor rendimiento lo consigue el modelo qSOFA 2 más lactato 2 mmol/l.

Utilidad del modelo 5MPB-Toledo para predecir bacteriemia en el paciente anciano / Usefulness of the 5MPB-Toledo model to predict bacteremia in the elderly patient

Resumen Objetivo: Analizar la utilidad del modelo predictivo de bacteriemia (5MPB-Toledo) en los mayores de 65 años atendidos por infección en el servicio de urgencias (SU). Material y Método: Estudio observacional prospectivo y multicéntrico de los hemocultivos (HC) obtenidos en pacientes mayores de 65 años atendidos por infección en 66 SU españoles desde el 1 de diciembre de 2019 hasta el 30 de abril de 2020. Se analizó la capacidad predictiva del modelo con el área bajo la curva (ABC) de la característica operativa del receptor (COR) y se calculó el rendimiento diagnóstico de los puntos de corte (PC) del modelo elegido con los cálculos de la sensibilidad, la especificidad, el valor predictivo positivo y el valor predictivo negativo. Resultados: Se incluyeron 2.401 episodios de HC extraídos. De ellos, se consideró como bacteriemia verdadera a 579 (24,11%) y como HC negativo a 1.822 (75,89%). Entre los negativos, 138 (5,74%) se consideraron contaminados. Se categorizó a los pacientes en bajo (0-2 puntos), moderado (3-5 puntos) y alto (6-8 puntos) riesgo, con una probabilidad de bacteriemia de 1,2%, 18,1% y 80,7%, respectivamente. El ABC-COR del modelo tras remuestreo fue de 0,908 (IC 95%: 0,897-0,924). El rendimiento diagnóstico del modelo, considerando un PC ≥ 5 puntos, obtiene una sensibilidad de 94% (IC 95%:92-96), especificidad de 77% (IC 95%:76-79) y un valor predictivo negativo de 97% (IC 95%:96-98). Conclusión: El modelo 5MPB-Toledo es de utilidad para predecir bacteriemia en los mayores de 65 años atendidos en el SU por un episodio de infección.

Abstract Objective: To analyse a risk score to predict bacteremia (MPB5-Toledo) in the patients aged older 65 years seen in the emergency departments (ED) due to infections. Patients and Methods: Prospective and multicenter observational cohort study of the blood cultures (BC) ordered in 66 Spanish ED for patients aged older 65 years seen from December 1, 2019, to April 30, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The prognostic performance for true bacteremia was calculated with the cut-off values chosen for getting the sensitivity, specificity, positive predictive value and negative predictive value. Results: A total of 2.401 blood samples wered cultured. True cases of bacteremia were confirmed in 579 (24.11%). The remaining 1.822 cultures (75.89%) wered negative. And, 138 (5.74%) were judged to be contaminated. Low risk for bacteremia was indicated by a score of 0 to 2 points, intermediate risk by 3 to 5 points, and high risk by 6 to 8 points. Bacteremia in these 3 risk groups was predicted for 1.2%, 18.1%, and 80.7%, respectively. The model´s area under the receiver ope rating characteristic curve was 0.908 (95% CI, 0.897-0.924). The prognostic performance with a model´s cut-off value of ≥ 5 points achieved 94% (95% CI: 92-96) sensitivity, 77% (95% CI: 76-79) specificity, and negative predictive value of 97% (95% CI: 96-98). Conclusion: The 5MPB-Toledo score is useful for predicting bacteremia in the patients aged older 65 years seen in the emergency departments due to infections.

The utility of the Barthel index as an outcome predictor in older patients with acute infection attending the emergency department.

BACKGROUND: Functional decline and frailty are common in older adults and influence the risk of adverse outcomes. We aimed to assess the value of a Barthel index at the Emergency Department (ED-BI) score in predicting 30-day mortality and ED reconsultation among older patients with acute infection. METHODS: We performed a prospective multicentre cohort study of older patients (≥75 years) diagnosed with acute infection in 69 Spanish EDs. Demographic, comorbidities, functional status, clinical and analytical data were collected. Unadjusted and adjusted logistic regression models were used to assess the association between ED-BI score, mortality and ED reconsultation. RESULTS: In total 1596 patients with a mean age of 84.7 years were included in the study and 51.7% female. The most frequent focus of infection was respiratory in 918 patients (57.5%). Patients with an ED-BI< 60 points were significantly older, predominantly female, more likely institutionalized and more urinary infections. When comparing patients with an ED-BI score ≥ 60 points with those< 60 points no differences were found in ED reconsultation but in the latter group mortality at 30-days was higher (p < 0.001). CONCLUSION: An ED-BI score< 60 points appears to be a strong predictor of mortality at the 30-day follow up in older patients with acute infection. DATA AVAILABILITY: The data used to support the findings of this study are included within the article.

Current Spanish emergency department organization and clinical practicesin caring for patients with acute heart failure. / Organización y práctica clínica actual en los servicios de urgencias españoles en la atención a los pacientes con insuficiencia cardiaca aguda.

OBJECTIVES: To describe routine diagnostic and therapeutic care processes and assignment of resources available for treating patients with acute heart failure (AHF) in Spanish hospital emergency departments (EDs). MATERIAL AND METHODS: We surveyed the heads of all hospital EDs in the Spanish national health service concerning their routine diagnostic, therapeutic, and decision-making processes for treating patients with AHF. Questions also covered processes related to continuity of care for patients after discharge. Responses were grouped by hospital size and location (Spanish autonomous community) for comparison. RESULTS: Heads of 250 of the 282 EDs (89%) responded. Thirty-two percent had a cardiologist on call, and a specialized AHF unit was present in 35%. Such untis were present in more than half the EDs in the Community of Madrid and in Catalonia. Eighty-four percent of EDs measured natriuretic peptide (NP) levels, 80% carried out echocardiographic assessments (although only 24% reported that more than half their staff were trained to undertake echocardiography), and 64% had high-flow nasal cannula (HFNC) systems. Only the Community of Valencia, Navarre, and La Rioja had the capacity for NP analysis, echocardiography, and HFNC therapy in 80% or more of their hospital EDs. Forty-six percent had admission protocols for patients with AHF, and 60% scheduled outpatient clinic appointments on discharge. Fifty-seven percent of the hospitals with AHF units had consensus-based protocols with their EDs, and 40% of them could schedule clinic appointments from the ED. Large hospitals had significantly better conditions with respect to some of these aspects of organization and care. CONCLUSION: There is room for improvement in the diagnosis and treatment of patients with AHF. We detected opportunities to ensure more effective continuity of care for these patients.

OBJETIVO: Conocer la práctica clínica diagnóstico-terapéutica y de disposición en los servicios de urgencias hospitalarios (SUH) españoles en los pacientes con insuficiencia cardiaca aguda (ICA). METODO: Encuesta a los responsables de todos los SUH públicos españoles sobre rutinas asistenciales diagnóstico-terapéuticas y de toma de decisión en urgencias en la atención a pacientes con ICA. Se indagaron procesos relacionados con la continuidad asistencial de pacientes dados de alta. Los resultados se comparan según tamaño del hospital y se detallan por comunidad autónoma. RESULTADOS: Respondieron 250 de los 282 SUH españoles (89%): 32% tenían cardiólogo de guardia y 35% unidad de insuficiencia cardiaca (UIC), presente en más del 50% de hospitales de la Comunidad de Madrid y Cataluña. El 84% de SUH determina péptidos natriuréticos (PN), 80% realiza evaluación ecográfica (aunque solo el 24% tiene más del 50% de sus facultativos formados) y el 64% dispone de cánulas nasales de alto flujo (CNAF). Solo la Comunidad Valenciana, Navarra y La Rioja disponen de PN, exploración ecográfica y CNAF en $ 80% de sus SUH. El 46% tiene protocolizado dónde ingresar el paciente con ICA y el 60% dan cita ambulatoria. Un 57% de los hospitales con UIC tienen un protocolo consensuado con el SUH: el 40% puede asignar la citación desde urgencias. Los hospitales grandes muestran datos significativamente mejores en algunas de las características anteriormente mencionadas. CONCLUSIONES: Existe margen de mejora en los SUH en cuanto a sus capacidades diagnóstico-terapéuticas de pacientes con ICA, y se detectan oportunidades para asegurar una continuidad asistencial más efectiva.

A case-control, multicentre study of consecutive patients with COVID-19 and acute (myo)pericarditis: incidence, risk factors, clinical characteristics and outcomes.

OBJECTIVE: To estimate incidence, risk factors, clinical characteristics and outcomes of acute (myo)pericarditis (AMP) in patients with COVID-19. METHODS: Case-control, retrospective review, consecutive case inclusion performed in 62 Spanish EDs. All COVID-19 patients with AMP (cases) were compared in clinical characteristics and outcomes with COVID-19 without AMP (control group A) and non-COVID patients with AMP (control group B). We estimated unadjusted standardised incidence (SI, not adjusted by population's age/sex) of AMP in COVID-19 and non-COVID populations (per 100 000/year). RESULTS: We identified 67 AMP in COVID-19 patients (SI=56.5, OR with respect to non-COVID patients=4.43, 95% CI=3.98 to 4.94). Remarkably, COVID-19 cases presented with chest pain less frequently than non-COVID patients and had less typical ECG changes, higher NT-proBNP (N-terminal prohormone of brain natriuretic peptide), more left and right ventricular dysfunction in echocardiography and more need of inotropic/vasopressor drugs. Admission to intensive care was higher than control group A (OR=3.22, 95% CI=1.43 to 7.23), and in-hospital mortality was higher than control group B (OR=7.75, 95% CI=2.77 to 21.7). CONCLUSION: AMP is unusual as a form of COVID-19 presentation (about 1‰ cases), but SI is more than fourfold higher than non-COVID population, and it is less symptomatic, more severe and has higher in-hospital mortality; therefore, rapid recognition, echocardiographic assessment of myopericardial inflammation/dysfunction and treatment with vasoactive drugs when needed are recommended in AMP in patients with COVID-19.

Pulmonary embolism severity and in-hospital mortality: An international comparative study between COVID-19 and non-COVID patients.

OBJECTIVE: To compare the severity of pulmonary embolism (PE) between patients with and without COVID, and to assess the association between severity and in-hospital-mortality. METHODS: We performed an analysis of 549 COVID (71.3% PCR-confirmed) and 439 non-COVID patients with PE consecutively included by 62 Spanish and 16 French emergency departments. PE-severity was assessed by size, the presence of right ventricular dysfunction (RVD), and the sPESI. The association of PE-severity and in-hospital-mortality was assessed both in COVID and non-COVID patients, and the interaction of COVID status and PE severity/outcome associations was also evaluated. RESULTS: COVID patients had PEs of smaller size (43% vs 56% lobar or larger, 42% vs. 35% segmental and 13% vs. 9% subsegmental, respectively; p = 0.01 for trend), less RVD (22% vs. 16%, p =0.02) and lower sPESI (p =0.03 for trend). Risk of in-hospital death was higher in COVID patients (12.8% vs. 5.3%, p < 0.001). PE-severity assessed by RVD and sPESI was independently associated with in-hospital-mortality in COVID patients, while PE size and sPESI were significantly associated with in-hospital-mortality in non-COVID. COVID status showed a significant interaction in the association of PE size and outcome (p =0.01), with OR for in-hospital mortality in COVID and non-COVID patients with lobar or larger PE of 0.92 (95%CI=0.19-4.47) and 4.47 (95%CI=1.60-12.5), respectively. Sensitivity analyses using only PCR-confirmed COVID cases confirmed these results. CONCLUSION: COVID patients present a differential clinical picture, with PE of less severity than in non-COVID patients. An increased sPESI was associated with the risk of mortality in both groups but, PE size did not seem to be associated with in-hospital mortality in COVID patients.

Incidence, Clinical Characteristics, Risk Factors and Outcomes of Acute Coronary Syndrome in Patients With COVID-19: Results of the UMC-19-S1010.

BACKGROUND: There is a lack of knowledge about the real incidence of acute coronary syndrome (ACS) in patients with COVID-19, their clinical characteristics, and their prognoses. OBJECTIVE: We investigated the incidence, clinical characteristics, risk factors, and outcomes of ACS in patients with COVID-19 in the emergency department. METHODS: We retrospectively reviewed all COVID-19 patients diagnosed with ACS in 62 Spanish emergency departments between March and April 2020 (the first wave of COVID-19). We formed 2 control groups: COVID-19 patients without ACS (control A) and non-COVID-19 patients with ACS (control B). Unadjusted comparisons between cases and control subjects were performed regarding 58 characteristics and outcomes. RESULTS: We identified 110 patients with ACS in 74,814 patients with COVID-19 attending the ED (1.48% [95% confidence interval {CI} 1.21-1.78%]). This incidence was lower than that observed in non-COVID-19 patients (3.64% [95% CI 3.54-3.74%]; odds ratio [OR] 0.40 [95% CI 0.33-0.49]). The clinical characteristics of patients with COVID-19 associated with a higher risk of presenting ACS were: previous coronary artery disease, age ≥60 years, hypertension, chest pain, raised troponin, and hypoxemia. The need for hospitalization and admission to intensive care and in-hospital mortality were higher in cases than in control group A (adjusted OR [aOR] 6.36 [95% CI 1.84-22.1], aOR 4.63 [95% CI 1.88-11.4], and aOR 2.46 [95% CI 1.15-5.25]). When comparing cases with control group B, the aOR of admission to intensive care was 0.41 (95% CI 0.21-0.80), while the aOR for in-hospital mortality was 5.94 (95% CI 2.84-12.4). CONCLUSIONS: The incidence of ACS in patients with COVID-19 attending the emergency department was low, around 1.48%, but could be increased in some circumstances. Patients with COVID-19 with ACS had a worse prognosis than control subjects with higher in-hospital mortality.

Validation of a predictive model for bacteraemia (MPB5-Toledo) in the patients seen in emergency departments due to infections.

OBJECTIVE: To validate a simple risk score to predict bacteremia (MPB5-Toledo) in patients seen in the emergency departments (ED) due to infections. METHODS: Prospective and multicenter observational cohort study of the blood cultures (BC) ordered in 74 Spanish ED for adults (aged 18 or older) seen from October 1, 2019, to February 29, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The prognostic performance for true bacteremia was calculated with the cut-off values chosen for getting the sensitivity, specificity, positive predictive value and negative predictive value. RESULTS: A total of 3.843 blood samples wered cultured. True cases of bacteremia were confirmed in 839 (21.83%). The remaining 3.004 cultures (78.17%) were negative. Among the negative, 172 (4.47%) were judged to be contaminated. Low risk for bacteremia was indicated by a score of 0-2 points, intermediate risk by 3-5 points, and high risk by 6-8 points. Bacteremia in these 3 risk groups was predicted for 1.5%, 16.8%, and 81.6%, respectively. The model's area under the receiver operating characteristic curve was 0.930 (95% CI, 0.916-0.948). The prognostic performance with a model's cut-off value of ≥5 points achieved 94.76% (95% CI: 92.97-96.12) sensitivity, 81.56% (95% CI: 80.11-82.92) specificity, and negative predictive value of 98.24% (95% CI: 97.62-98.70). CONCLUSION: The 5MPB-Toledo score is useful for predicting bacteremia in patients attended in hospital emergency departments for infection.

A bacteraemia risk prediction model: development and validation in an emergency medicine population.

OBJECTIVE: Design a risk model to predict bacteraemia in patients attended in emergency departments (ED) for an episode of infection. METHODS: This was a national, prospective, multicentre, observational cohort study of blood cultures (BC) collected from adult patients (≥ 18 years) attended in 71 Spanish EDs from October 1 2019 to March 31, 2020. Variables with a p value < 0.05 were introduced in the univariate analysis together with those of clinical significance. The final selection of variables for the scoring scale was made by logistic regression with selection by introduction. The results obtained were internally validated by dividing the sample in a derivation and a validation cohort. RESULTS: A total of 4,439 infectious episodes were included. Of these, 899 (20.25%) were considered as true bacteraemia. A predictive model for bacteraemia was defined with seven variables according to the Bacteraemia Prediction Model of the INFURG-SEMES group (MPB-INFURG-SEMES). The model achieved an area under the curve-receiver operating curve of 0.924 (CI 95%:0.914-0.934) in the derivation cohort, and 0.926 (CI 95%: 0.910-0.942) in the validation cohort. Patients were then split into ten risk categories, and had the following rates of risk: 0.2%(0 points), 0.4%(1 point), 0.9%(2 points), 1.8%(3 points), 4.7%(4 points), 19.1% (5 points), 39.1% (6 points), 56.8% (7 points), 71.1% (8 points), 82.7% (9 points) and 90.1% (10 points). Findings were similar in the validation cohort. The cut-off point of five points provided the best precision with a sensitivity of 95.94%, specificity of 76.28%, positive predictive value of 53.63% and negative predictive value of 98.50%. CONCLUSION: The MPB-INFURG-SEMES model may be useful for the stratification of risk of bacteraemia in adult patients with infection in EDs, together with clinical judgement and other variables independent of the process and the patient.

Sociodemographic characteristics, functional status, and health resource use of older patients treated in Spanish emergency departments: a description of the EDEN cohort. / Características sociodemográficas, funcionales y consumo de recursos de la población mayor atendida en los servicios de urgencias españoles: una aproximación desde la cohorte EDEN.

OBJECTIVES: To describe the sociodemographic characteristics of and the health care resources used to treat patients aged 65 years or older who come to hospital emergency departments (EDs) in Spain, according to age groups. MATERIAL AND METHODS: We studied the phase-1 data for the EDEN cohort (Emergency Department and Elder Needs). Forty Spanish EDs collected data on all patients aged 65 years or older who were treated on the first 7 days in April 2019. We registered information on 6 sociodemographic and 5 function variables for all patients. For health resource use we used 6 diagnostic, 13 therapeutic, and 5 physical structural variables, for a total of 24 variables. Differences were analyzed according to age in blocks of 5 years. RESULTS: A total of 18 374 patients with a median age of 78 years were included; 55% were women. Twenty-seven percent arrived by ambulance, 71% had not previously been seen by a physician, and 13% lived alone without assistance. Ten percent had a high level of functional dependence, and 14% had serious comorbidity. Resources used most often were blood analysis (in 60%) and radiology (59%), analgesics (25%), intravenous fluids (21%), antibiotics (14%), oxygen (13%), and bronchodilators (11%). Twenty-six percent were kept under observation in the ED, 26% were admitted to wards, and 2% were admitted to intensive care units (ICUs). The median stay in the ED was 3.5 hours, and the median hospital stay was 7 days. Sociodemographic characteristics changed according to age. Functional dependence worsened with age, and resource requirements increased in general. However, benzodiazepine use was unaffected, while the use of nonsteroidal anti-inflammatory drugs and ICU admission decreased. CONCLUSION: The functional dependence of older patients coming to EDs increases with age and is associated with a high level of health care resource use, which also increases with age. Planners should take into consideration the characteristics of the older patients and the proportion of the caseload they represent when arranging physical spaces and designing processes for a specific ED.

OBJETIVO: Investigar las características sociodemográficas y consumo de recursos de los pacientes de 65 o más años que consultan en servicios de urgencias hospitalarios (SUH) en España, y su modificación por grupos etarios. METODO: Se utilizaron datos de la cohorte EDEN obtenidos en fase 1 (Emergency Department and Elder Needs). Cuarenta SUH españoles incluyeron todos los pacientes de $ 65 años atendidos del 1-4-2019 al 7-4-2019 (7 días). Se analizaron 6 características sociodemográficas, 5 funcionales y 24 referidas a consumo de recursos (6 diagnósticos, 13 terapéuticos, 5 estructurales) y sus cambios a medida que avanza la edad (agrupada en bloques de 5 años). RESULTADOS: Se analizaron 18.374 pacientes (mediana edad: 78 años; 55% mujeres). El 27% acude a urgencias en ambulancia, el 71% sin consulta médica previa y el 13% vive solo sin cuidadores. Funcionalmente, el 10% tiene dependencia grave y el 14% comorbilidad grave. La solicitud de analítica sanguínea (60% de casos) y radiología (59%) destaca entre el consumo de recursos diagnósticos, y el uso de analgésicos (25%), sueroterapia (21%), antibioticoterapia (14%), oxigenoterapia (13%) y broncodilatadores (11%), entre los terapéuticos. El 26% requiere observación en urgencias, el 26% hospitalización y el 2% cuidados intensivos. La mediana de estancia en urgencias es de 3:30 horas y la de hospitalización es de 7 días. Las características sociodemográficas se modifican con la edad, las funcionales empeoran y el consumo de recursos aumenta (excepto benzodiacepinas, que no se modifica, y antinflamatorios no esteroideos y cuidados intensivos, que disminuye). CONCLUSIONES: Las características funcionales de la población mayor que consulta en los SUH empeora a medida que su edad avanza, y se asocia a un consumo de recursos alto que también se incrementa con la edad. Las características de esta población y su proporción en un determinado SUH deben tenerse en cuenta en su planificación estructural y funcional.

Sociodemographic characteristics, comorbidity, and baseline functional status of older patients treated in emergency departments during the COVID-19 pandemic and associations with mortality: an analysis based on the EDENCOVID cohort. / Sociodemografía, comorbilidad y situación funcional basal de los pacientes mayores atendidos en urgencias durante la pandemia de COVID y su relación con la mortalidad: análisis a partir de la cohorte EDEN-Covid.

OBJECTIVES: To describe the sociodemographic characteristics, comorbidity, and baseline functional status of patients aged 65 or older who came to hospital emergency departments (EDs) during the first wave of the COVID-19 pandemic, and to compare them with the findings for an earlier period to analyze factors of the index episode that were related to mortality. MATERIAL AND METHODS: We studied data from the EDEN-COVID cohort (Emergency Department and Elder Needs During COVID-19) of patients aged 65 years or older treated in 40 Spanish EDs on 7 consecutive days. Nine sociodemographic variables, 18 comorbidities, and 7 function variables were registered and compared with the findings for the EDEN cohort of patients included with the same criteria and treated a year earlier in the same EDs. In-hospital mortality was calculated in the 2 cohorts and a multivariable logistic regression model was used to explore associated factors. RESULTS: The EDEN-COVID cohort included 6806 patients with a median age of 78 years; 49% were women. The pandemic cohort had a higher proportion of men, patients covered by the national health care system, patients brought from residential facilities, and patients who arrived in an ambulance equipped for advanced life support. Pandemic-cohort patients more often had diabetes mellitus, chronic kidney disease, and dementia; they less often had connective tissue and thromboembolic diseases. The Barthel and Charlson indices were worse in this period, and cognitive decline was more common. Fewer patients had a history of depression or falls. Eight hundred ninety these patients (13.1%) died, 122 of them in the ED (1.8%); these percentages were lower in the earlier EDEN cohort, at 3.1% and 0.5%, respectively. Independent sociodemographic factors associated with higher mortality were transport by ambulance, older age, male sex, and living in a residential facility. Mortalityassociated comorbidities were neoplasms, chronic kidney disease, and heart failure. The only function variable associated with mortality was the inability to walk independently. A history of falls in the past 6 months was a protective factor. CONCLUSION: The sociodemographic characteristics, comorbidity, and functional status of patients aged 65 years or older who were treated in hospital EDs during the pandemic differed in many ways from those usually seen in this older-age population. Mortality was higher than in the prepandemic period. Certain sociodemographic, comorbidity, and function variables were associated with in-hospital mortality.

OBJETIVO: Investigar sociodemografía, comorbilidad y situación funcional de los pacientes de 65 o más años de edad que consultaron a los servicios de urgencias hospitalarios (SUH) durante la primera oleada epidémica de COVID, compararlas con un periodo previo y ver su relación. METODO: Se utilizaron los datos obtenidos de la cohorte EDEN-Covid (Emergency Department and Elder Needs during COVID) en la que participaron 40 SUH españoles que incluyeron todos los pacientes de $ 65 años atendidos durante 7 días consecutivos. Se analizaron 9 características sociodemográficas, 18 comorbilidades y 7 variables de funcionalidad, que se compararon con las de la cohorte EDEN (Emergency Department and Elder Needs), que contiene pacientes con el mismo criterio de inclusión etario reclutados por los mismos SUH un año antes. Se recogió la mortalidad intrahospitalaria y se investigaron los factores asociados mediante regresión logística multivariable. RESULTADOS: La cohorte EDEN-Covid incluyó 6.806 pacientes (mediana edad: 78 años; 49% mujeres). Hubo más varones, con cobertura sanitaria pública, procedentes de residencia y que llegaron con ambulancia medicalizada que durante el periodo prepandemia. Presentaron más frecuentemente diabetes mellitus, enfermedad renal crónica, enfermedad cerebrovascular y demencia y menos conectivopatías y enfermedad tromboembólica, peores índices de Barthel y Charlson, más deterioro cognitivo y menos antecedentes de depresión o caídas previas. Fallecieron durante el episodio 890 pacientes (13,1%), 122 de ellos en urgencias (1,8%), porcentajes superiores al periodo prepandemia (3,1% y 0,5%, respectivamente). Se asociaron de forma independiente a mayor mortalidad durante el periodo COVID la llegada en ambulancia, mayor edad, ser varón y vivir en residencia como variables sociodemográficas, y neoplasia, enfermedad renal crónica e insuficiencia cardiaca como comorbilidades. La única variable funcional asociada a mortalidad fue no deambular respecto a ser autónomo, y la existencia de caídas los 6 meses previos resultó un factor protector. CONCLUSIONES: La sociodemografía, comorbilidad y funcionalidad de los pacientes de 65 o más años que consultaron en los SUH españoles durante la primera ola pandémica difirieron en muchos aspectos de lo habitualmente observado en esta población. La mortalidad fue mayor a la del periodo prepandémico. Algunos aspectos sociodemográficos, de comorbilidad y funcionales se relacionaron con la mortalidad intrahospitalaria.
