RESUMO

OBJECTIVES: To study the frequency of physical frailty and explore whether its presence in older patients with acute heart failure (AHF) is associated with adverse outcomes in the year after discharge from a emergency department (ED). MATERIAL AND METHODS: Prospective observational cohort study in patients with AHF aged 75 years or older who were discharged from our ED. Physical frailty was defined by a score of 7 or less on the Short Physical Performance Battery. The outcome was the development of a composite event (ED revisit for AHF, hospital readmission for AHF, or all-cause mortality) within 365 days of discharge from the ED. RESULTS: Eighty-six patients with a mean (SD) age of 84 (6) years were included; 59.3% were women. Frailty was identified in 49 patients (57%). The composite outcome was observed in 46.5% within 365 days. Physical fragility was an independent predictor of the outcome (adjusted odds ratio, 3.6; 95% CI, 1.0-12.9; P=.047). CONCLUSION: Frailty in older patients with AHF may predict a poor outcome during the year following discharge from an emergency department.

RESUMO

BACKGROUND: We aimed to validate the clinical performance of the high-sensitivity cardiac troponin I [VITROS® Immunodiagnostic Products hs Troponin I (hs-cTnI-VITROS)] assay. METHODS: We enrolled patients presenting to the emergency department with symptoms suggestive of acute myocardial infarction (AMI). Final diagnoses were centrally adjudicated by 2 independent cardiologists considering all clinical information, including cardiac imaging: first, using serial hs-cTnT-Elecsys (primary analysis) and, second, using hs-cTnI-Architect (secondary analysis) measurements in addition to the clinically used (hs)-cTn. hs-cTnI-VITROS was measured at presentation and at 1 h in a blinded fashion. The primary objective was direct comparison of diagnostic accuracy as quantified by the area under the ROC curve (AUC) of hs-cTnI-VITROS vs hs-cTnT-Elecsys and hs-cTnI-Architect, and in a subgroup also hs-cTnI-Centaur and hs-cTnI-Access. Secondary objectives included the derivation and validation of an hs-cTnI-VITROS-0/1-h algorithm. RESULTS: AMI was the adjudicated final diagnosis in 158 of 1231 (13%) patients. At presentation, the AUC for hs-cTnI-VITROS was 0.95 (95% CI, 0.93-0.96); for hs-cTnT-Elecsys, 0.94 (95% CI, 0.92-0.95); and for hs-cTnI-Architect, 0.92 (95% CI, 0.90-0.94). AUCs for hs-cTnI-Centaur and hs-cTnI-Access were 0.95 (95% CI, 0.94-0.97). Applying the derived hs-cTnI-VITROS-0/1-h algorithm (derivation cohort n = 519) to the validation cohort (n = 520), 53% of patients were ruled out [sensitivity, 100% (95% CI, 94.1-100)] and 14% of patients were ruled in [specificity, 95.6% (95% CI, 93.4-97.2)]. Patients ruled out by the 0/1-h algorithm had a survival rate of 99.8% at 30 days. Findings were confirmed in the secondary analyses using the adjudication including serial measurements of hs-cTnI-Architect. CONCLUSIONS: The hs-cTnI-VITROS assay has at least comparable diagnostic accuracy with the currently best validated hs-cTnT and hs-cTnI assays. CLINICALTRIALSGOV IDENTIFIER: NCT00470587.

RESUMO

BACKGROUND: Early and accurate detection of short-term major adverse cardiac events (MACE) in patients with suspected acute myocardial infarction (AMI) is an unmet clinical need. OBJECTIVES: The goal of this study was to test the hypothesis that adding clinical judgment and electrocardiogram findings to the European Society of Cardiology (ESC) high-sensitivity cardiac troponin (hs-cTn) measurement at presentation and after 1 h (ESC hs-cTn 0/1 h algorithm) would further improve its performance to predict MACE. METHODS: Patients presenting to an emergency department with suspected AMI were enrolled in a prospective, multicenter diagnostic study. The primary endpoint was MACE, including all-cause death, cardiac arrest, AMI, cardiogenic shock, sustained ventricular arrhythmia, and high-grade atrioventricular block within 30 days including index events. The secondary endpoint was MACE + unstable angina (UA) receiving early (≤24 h) revascularization. RESULTS: Among 3,123 patients, the ESC hs-cTnT 0/1 h algorithm triaged significantly more patients toward rule-out compared with the extended algorithm (60%; 95% CI: 59% to 62% vs. 45%; 95% CI: 43% to 46%; p < 0.001), while maintaining similar 30-day MACE rates (0.6%; 95% CI: 0.3% to 1.1% vs. 0.4%; 95% CI: 0.1% to 0.9%; p = 0.429), resulting in a similar negative predictive value (99.4%; 95% CI: 98.9% to 99.6% vs. 99.6%; 95% CI: 99.2% to 99.8%; p = 0.097). The ESC hs-cTnT 0/1 h algorithm ruled-in fewer patients (16%; 95% CI: 14.9% to 17.5% vs. 26%; 95% CI: 24.2% to 27.2%; p < 0.001) compared with the extended algorithm, albeit with a higher positive predictive value (76.6%; 95% CI: 72.8% to 80.1% vs. 59%; 95% CI: 55.5% to 62.3%; p < 0.001). For 30-day MACE + UA, the ESC hs-cTnT 0/1 h algorithm had a higher positive predictive value for rule-in, whereas the extended algorithm had a higher negative predictive value for the rule-out. Similar findings emerged when using hs-cTnI. CONCLUSIONS: The ESC hs-cTn 0/1 h algorithm better balanced efficacy and safety in the prediction of MACE, whereas the extended algorithm is the preferred option for the rule-out of 30-day MACE + UA.

RESUMO

BACKGROUND: The prevalence of pulmonary embolism (PE) in patients presenting with syncope to the emergency department (ED) is largely unknown. This information, however, is necessary to balance the potential medical benefit or harm of systematic PE screening in patients presenting with syncope to the ED. OBJECTIVES: This study sought to determine the prevalence of PE in patients with syncope. METHODS: Unselected patients presenting with syncope to the ED were prospectively enrolled in a diagnostic multicenter study. Pre-test clinical probability for PE was assessed using the 2-level Wells score and the results of D-dimer testing using age-adapted cutoffs. Presence of PE was evaluated by imaging modalities, when ordered as part of the clinical assessment by the treating ED physician or by long-term follow-up data. RESULTS: Long-term follow-up was complete in 1,380 patients (99%) at 360 days and 1,156 patients (83%) at 720 days. Among 1,397 patients presenting with syncope to the ED, PE was detected at presentation in 19 patients (1.4%; 95% confidence interval [CI]: 0.87% to 2.11%). The incidence of new PEs or cardiovascular death during 2-year follow-up was 0.9% (95% CI: 0.5% to 1.5%). In the subgroup of patients hospitalized (47%), PE was detected at presentation in 15 patients (2.3%; 95% CI: 1.4% to 3.7%). The incidence of new PEs or cardiovascular death during 2-year follow-up was 0.9% (95% CI: 0.4% to 2.0%). CONCLUSIONS: PE seems to be a rather uncommon cause of syncope among patients presenting to the ED. Therefore, systematic PE-screening in all patients with syncope does not seem warranted.

RESUMO

BACKGROUND: The aim of this study was to validate the clinical performance of the Beckman Access high-sensitivity cardiac troponin I (hs-cTnI) assay. METHODS: We enrolled patients presenting to the emergency department with symptoms suggestive of acute myocardial infarction (AMI). Final diagnoses were centrally adjudicated by 2 independent cardiologists with all clinical information including cardiac imaging twice: first, using serial hs-cTnT (Elecsys, primary analysis), and second, using hs-cTnI (Architect, secondary analysis) measurements in addition to the clinically used hs-cTn. hs-cTnI Access was measured at presentation and at 1 h. The primary objective was a direct comparison of diagnostic accuracy as quantified by the area under the ROC curve (AUC) of hs-cTnI Access vs the hs-cTnT Elecsys and hs-cTnI Architect assays. Secondary objectives included the derivation and validation of an hs-cTnI Access-specific 0/1-h algorithm. RESULTS: AMI was the adjudicated final diagnosis in 243 of 1579 (15.4%) patients. The AUC at presentation for hs-cTnI Access was 0.95 (95% CI, 0.94-0.96), higher than hs-cTnI Architect [0.92 (95% CI, 0.91-0.94; P < 0.001)] and comparable to hs-cTnT Elecsys [0.94 (95% CI, 0.93-0.95; P = 0.12)]. Applying the derived hs-cTnI Access 0/1-h algorithm (derivation cohort n = 686) to the validation cohort (n = 680), 60% of patients were ruled out [sensitivity, 98.9% (95% CI, 94.3-99.8)], and 15% of patients were ruled in [specificity, 95.9% (95% CI, 94.0-97.2)]. Patients ruled out by the 0/1-h algorithm had a survival rate of 100% at 30 days. Findings were confirmed in the secondary analyses by the adjudication including serial measurements of Architect hs-cTnI. CONCLUSIONS: Diagnostic accuracy and clinical utility of the Beckman hs-cTnI Access assay are very high and at least comparable to Roche hs-cTnT and Abbott hs-cTnI assays.

RESUMO

BACKGROUND: The utility of B-type Natriuretic Peptide (BNP), N-terminal proBNP (NT-proBNP), and high-sensitivity cardiac troponin (hs-cTn) concentrations for diagnosis and risk-stratification of syncope is incompletely understood. METHODS: We evaluated the diagnostic and prognostic accuracy of BNP, NT-proBNP, hs-cTnT, and hs-cTnI concentrations, alone and against the ones of clinical assessments, in patients >45years presenting with syncope to the emergency department (ED) in a prospective diagnostic multicenter study. BNP, NT-proBNP, hs-cTnT and hs-cTnI concentrations were measured in a blinded fashion. Cardiac syncope, as adjudicated by two physicians based on all information available including cardiac work-up and 1-year follow-up, was the diagnostic endpoint. The EGSYS, a syncope-specific diagnostic score, served as the diagnostic comparator. Death and MACE at 30 and 720 days were the prognostic endpoints. MACE were defined as death, cardiopulmonary resuscitation, life-threatening arrhythmia, implantation of pacemaker/implantable cardioverter defibrillator, acute myocardial infarction, pulmonary embolism, stroke/transient ischemic attack, intracranial bleeding or valvular surgery. The ROSE, OESIL, San Fransisco Syncope Rule (SFSR) and Canadian Syncope Risk Score (CSRS) served as the prognostic comparators. RESULTS: Among 1538 patients eligible for diagnostic assessment, cardiac syncope was the adjudicated diagnosis in 234 patients (15.2%). BNP, NT-proBNP, hs-cTnT, and hs-cTnI were significantly higher in cardiac syncope vs. other causes (p<0.01). The diagnostic accuracy for cardiac syncope, as quantified by the area under the curve (AUC), was 0.77-0.78 (95% confidence interval (CI) 0.74-0.81) for all four biomarkers, and superior to the one of EGSYS (AUC 0.68 [95%-CI 0.65-0.71], p<0.001). Combining BNP/NT-proBNP with hs-cTnT/hs-cTnI further improved diagnostic accuracy to an AUC of 0.81 (p<0.01). BNP, NT-proBNP, hs-cTnT, and hs-cTnI cut-offs, achieving pre-defined thresholds for sensitivity and specificity (95%), allowed for rule-in or rule-out of ~30% of all patients. A total of 450 MACE occurred during follow-up. The prognostic accuracy of BNP, NT-proBNP, hs-cTnI, and hs-cTnT for MACE was moderate-to-good (AUC 0.75-0.79), superior to ROSE, OESIL and SFSR, and inferior to the CSRS. CONCLUSIONS: BNP, NT-proBNP, hs-cTnT, and hs-cTnI concentrations provide useful diagnostic and prognostic information in ED patients with syncope.

RESUMO

BACKGROUND: We desired to determine cardiac troponin (cTn) concentrations necessary to achieve a positive predictive value (PPV) of ≥75% for acute myocardial infarction (AMI) to justify immediate admission of patients to a monitored unit and, in general, early coronary angiography. METHODS: In a prospective multicenter diagnostic study enrolling patients presenting to the emergency department with symptoms suggestive of AMI, final diagnoses were adjudicated by 2 independent cardiologists based on clinical information including cardiac imaging. cTn concentrations were measured using 5 different sensitive and high-sensitivity cTn (hs-cTn) assays in a blinded fashion at presentation and serially thereafter. The diagnostic end point was PPV for rule-in of AMI of initial cTn concentrations alone and in combination with early changes. RESULTS: Among 3828 patients, 616 (16%) had an AMI. At presentation, 7% to 14% of patients had cTnT/I concentrations associated with a PPV of ≥75%. Adding absolute or relative changes did not significantly further increase the PPV. PPVs increased from 46.5% (95% CI, 43.6-49.4) for hs-cTnT at presentation >14 ng/L to 78.9% (95% CI, 74.7-82.5) for >52 ng/L (P < 0.001), whereas PPVs in higher hs-cTnT strata remained largely unchanged [e.g., 82.4% (95% CI, 77.5-86.7) for >80 ng/L vs 83.9% (95% CI, 76.0-90.1) for >200 ng/L (P = 0.72)]. The addition of early changes in hs-cTnT further increased the PPV up to 60 ng/L, but not for higher concentrations. CONCLUSIONS: Serial sampling does not seem necessary for predicting AMI and concurrent decision-making in about 10% of patients, as it only marginally increases the PPV for AMI and not in a statistically or clinically significant way.

RESUMO

La fragilidad es un síndrome clínico que ocurre durante el envejecimiento, que se caracteriza por una disminución de la reserva fisiológica ante una situación de estrés y constituye un estado de vulnerabilidad que conlleva mayor riesgo de un resultado adverso. Su prevalencia en España es alta, especialmente en ancianos con comorbilidad y enfermedades crónicas. En el caso de la enfermedad cardiovascular, la fragilidad determina peores resultados clínicos, con mayor morbimortalidad en todos los escenarios, agudos y crónicos; por lo tanto, puede condicionar el diagnóstico y el tratamiento de los pacientes. A pesar de todo ello, se trata de un problema que con frecuencia no se aborda ni se incluye al planificar la atención al paciente mayor con cardiopatía. En este trabajo se repasa la evidencia científica disponible y se destacan las escalas más adecuadas para la medición y la valoración de la fragilidad, algunas con mayor utilidad y mejor capacidad predictiva según el contexto clínico en que se apliquen, y se resalta también la importancia de evaluarla para identificar su presencia e incluirla en el plan individualizado de tratamiento y cuidados que mejor se adapte a cada paciente


Frailty is an age-associated clinical syndrome characterized by a decrease in physiological reserve in situations of stress, constituting a state of vulnerability that involves a higher risk of adverse events. Its prevalence in Spain is high, especially in elderly individuals with comorbidity and chronic diseases. In cardiovascular disease, frailty is associated worse clinical outcomes and higher morbidity and mortality in all scenarios, in both acute and chronic settings, and could consequently influence diagnosis and treatment. However, frailty is often not addressed or included when planning the management of elderly patients with heart disease. In this article, we review the available scientific evidence and highlight the most appropriate scales for the measurement and assessment of frailty, some of which are more useful and have better predictive capacity than others, depending on the clinical context. We also underline the importance of properly identifying and assessing frailty in order to include it in the treatment and care plan that best suits each patient

RESUMO

BACKGROUND: The value of the 12-lead ECG in the diagnosis of non-ST-elevation myocardial infarction (NSTEMI) is limited due to insufficient sensitivity and specificity of standard ECG criteria. The QRS-T angle reflects depolarization-repolarization heterogeneity and might assist in detecting patients with a NSTEMI (diagnosis) as well as predicting patients with an increased mortality risk (prognosis). METHODS: We prospectively enrolled 2705 consecutive patients with symptoms suggestive of NSTEMI. The QRS-T angle was automatically derived from the standard 10 s 12-lead ECG recorded at presentation to the ED. Patients were followed up for all-cause mortality for 2 years. RESULTS: NSTEMI was the final diagnosis in 15% (n = 412) of patients. QRS-T angles were significantly greater in patients with NSTEMI compared to those without (p < 0.001). The use of the QRS-T angle in addition to standard ECG criteria indicative of ischemia improved the diagnostic accuracy for NSTEMI as quantified by the area under the ROC curve from 0.68 to 0.72 (p < 0.001). An algorithm for the combined use of standard ECG criteria and the QRS-T angle improved the sensitivity of the ECG for NSTEMI from 45% to 78% and the specificity from 86% to 91% (p < 0.001 for both comparisons). The 2-year survival rates were 98%, 97% and 87% according to QRS-T angle tertiles (p < 0.001). CONCLUSION: In patients with suspected NSTEMI, the QRS-T angle derived from the standard 12-lead ECG provides incremental diagnostic accuracy on top of standard ECG criteria indicative of ischemia, and independently predicts all-cause mortality during 2 years of follow-up.

RESUMO

Objetivo. Profundizar en el conocimiento y la evolución de la Medicina de Urgencias y Emergencias (MUE) en España a través del análisis de las ponencias presentadas en los congresos de la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES) celebrados los últimos 30 años (1988-2017). Método. Se revisaron los programas de todos los Congresos SEMES y se analizaron las características de ponencias y ponentes, así como la evolución entre 1988-2017 de algunas de estas características. Se revisó en Web of Science la producción científica y el índice h de los ponentes más frecuentes para contrastar su relevancia científica. Resultados. En los 29 Congresos SEMES (en 1992 no se celebró) se han presentado 2.182 ponencias (112 internacionales) por 1.410 ponentes (89 internacionales) procedentes de 616 centros. Hubo un crecimiento lineal de ponencias y ponentes los primeros años, una posterior fase de meseta, y finalmente un crecimiento con tendencia exponencial el último lustro. El 79,6% de ponencias fue impartida por hombres, y la distribución de médicos/enfermeros/técnicos fue 70,6%/11,9%/4,0%. Los urgenciólogos realizaron el 60,8% de ponencias médicas. La comunidad autónoma organizadora del congreso aportó el 29,8% de ponencias, casi siempre por encima de lo esperable por su aportación promedio global. Hubo comunidades autónomas cuya participación estuvo muy por debajo de su productividad científica (Extremadura, Andalucía, Cataluña) y otras muy por encima (Murcia, Baleares, Asturias, Castilla-León, Madrid). El 64,4% de los 59 ponentes más asiduos ( 5 congresos) tiene publicados 20 artículos y el 71,2% tiene un índice h 5. Entre 1988-2017 hubo incremento significativo de mujeres ponentes, diversificación geográfica (ponencias de comunidades autónomas no organizadoras del congreso) y urgenciólogos hospitalarios. Conclusiones. Hubo un aumento significativo de ponencias y ponentes en los Congresos SEMES, con cambios detectables en algunas de sus características. El análisis detallado puede permitir intervenciones para corregir algunos aspectos en futuros Congresos SEMES, tales como la escasa diversificación y participación internacional y de mujeres


Objective. To gain greater understanding of the development of emergency medicine in Spain by analyzing the presentations at conferences of the Spanish Society of Emergency Medicine (SEMES) over the past 30 years (1988–2017). Methods. We examined the programs of all SEMES conferences and described the characteristics of both presentations and presenters. We also analyzed changes occurring between 1988 and 2017 of some of the characteristics observed. The Web of Science was searched to evaluate the scientific productivity of the most frequent presenters and to calculate h-indexes for those presenters to assesstheir scientific relevance. Results. SEMES did not hold a conference in 1992. The total of 29 conferences included 2182 presentations (112 listing presenters from abroad) given by 1410 presenters (89 from abroad). The presenters' affiliations named 616 centers. The number of presentations and presenters increased linearly during the first period and then leveled off. The number increased exponentially in the final phase. Men gave 79.6% of the presentations; 70.6% of the presenters were physicians, 11.9% were nurses and 4.0% were ambulance staff. Specialists in emergency medicine accounted for 60.8% of the presenters who were physicians. Presenters from the Spanish autonomous community organizing the conference gave 29.8% of the presentations. The contributions of presenters from the local organizing community were nearly always more numerous than the average number of contributions from that community in all 29 conferences overall. Conference contributions from some autonomous communities (Extremadura, Andalusia, and Catalonia) were considerably fewer than would be expected given the scientific productivity of those communities. However, communities (Murcia, Balearic Islands, Asturias, Castile-Leon, Madrid), gave many more presentations than their productivity metrics would predict. Analysis of the 59 most frequent presenters (at 5 conferences or more) showed that 64.4% of them had published at least 20 articles and that 71.2% had an h-index of 5 or higher. The number of women on the program increased significantly between 1988 and 2017. Likewise, geographic diversity increased significantly (presentations from centers outside the local organizing area) as did the participation of hospitalbased emergency medicine specialists. Conclusions. SEMES conference programs have attracted significantly more presentations and presenters over the years. We also detected changes in descriptive characteristics. The analysis of those characteristics can help future SEMES conference planners to plan ways to correct aspects such as scarce geographic diversity, low international participation, and few women among presenters

RESUMO

Objetivos. Diseñar una escala de puntuación multidimensional con el fin de estratificar el riesgo de mortalidad a 180 días entre los ancianos ingresados en las unidades de corta estancia (UCE). Métodos. Estudio analítico observacional de cohortes prospectivo multicéntrico que seleccionó todos los pacientes >= 75 años ingresados en 5 UCE españolas del 1 de febrero al 30 de abril de 2014. Se recogieron variables demográficas, clínicas y de la valoración geriátrica. Se derivó un modelo de regresión logística multinivel para identificar los factores independientemente asociados con la mortalidad a 180 días y después se construyó una escala de puntuación. Resultados. Se incluyeron 593 pacientes (edad media 83,4 años, DE: 5,9; 359 mujeres, 60,7%), y 92 (15,5%) fallecieron a los 180 días. La escala de puntuación 6M UCE-SCORE incluyó la edad >= 85 años (1 punto), sexo varón (1 punto), presencia de pérdida de apetito o peso involuntaria en los últimos 3 meses (1 punto), síndrome confusional agudo (2 puntos), dependencia en las actividades básicas de la vida diaria al ingreso (2 puntos) y úlceras por presión (2 puntos). Se categorizó a los pacientes en bajo (0-2 puntos), intermedio (3-5 puntos) y alto (6-9 puntos) riesgo, con una mortalidad a 180 días de 5%, 18% y 54%, respectivamente. El ABC COR del modelo tras remuestreo fue de 0,72 (IC95%: 0,65-0,78). Conclusiones. La escala de puntuación 6M UCE-SCORE podría ser de utilidad a la hora de estratificar el riesgo a 6 meses entre los ancianos ingresados en las UCE con el fin de diseñar un plan individualizado de cuidados


Objectives. To develop a multidimensional score to assess risk of death for patients of advanced age 180 days after their admission to short-stay units (SSUs). Methods. Prospective, multicenter, observational and analytical study of a cohort of patients aged 75 years or older who were admitted to 5 Spanish SSUs between February 1 and April 30, 2014. We recorded demographic and clinical data as well as geriatric assessment scores. A multilevel logistic regression model was developed to identify independent factors associated with 180-day mortality. The model was used to construct a scale for scoring risk. Results. Data for 593 patients with a mean (SD) age of 83.4 (5.9) years entered the model; 359 (60.7%) were women. Ninety-two patients (15.5%) died within 180 days of SSU admission. Factors included in the final risk score were age over 85 years (1 point), male sex (1), loss of appetite or weight loss in the 3 months before admission (1), acute confusional state (2), functional dependence for basic activities of daily living at admission (2), and pressure ulcers (2). Low risk was indicated by a score of 0 to 2 points, intermediate risk by 3 to 5 points, and high risk by 6 to 9 points. Mortality rates at 180 days in these 3 risk groups were 5%, 18%, and 54%, respectively. The area under the receiver operating characteristic curve for the model after boots trapping was 0.72 (95% CI, 0.65–0.78). Conclusion. The SSU score could be useful for stratifying risk of death within 6 months of SSU admission of older patients, so that type of care can be tailored to risk

OBJECTIVES: To gain greater understanding of the development of emergency medicine in Spain by analyzing the presentations at conferences of the Spanish Society of Emergency Medicine (SEMES) over the past 30 years (1988-2017). MATERIAL AND METHODS: We examined the programs of all SEMES conferences and described the characteristics of both presentations and presenters. We also analyzed changes occurring between 1988 and 2017 of some of the characteristics observed. The Web of Science was searched to evaluate the scientific productivity of the most frequent presenters and to calculate h-indexes for those presenters to assesstheir scientific relevance. RESULTS: SEMES did not hold a conference in 1992. The total of 29 conferences included 2182 presentations (112 listing presenters from abroad) given by 1410 presenters (89 from abroad). The presenters' affiliations named 616 centers. The number of presentations and presenters increased linearly during the first period and then leveled off. The number increased exponentially in the final phase. Men gave 79.6% of the presentations; 70.6% of the presenters were physicians, 11.9% were nurses and 4.0% were ambulance staff. Specialists in emergency medicine accounted for 60.8% of the presenters who were physicians. Presenters from the Spanish autonomous community organizing the conference gave 29.8% of the presentations. The contributions of presenters from the local organizing community were nearly always more numerous than the average number of contributions from that community in all 29 conferences overall. Conference contributions from some autonomous communities (Extremadura, Andalusia, and Catalonia) were considerably fewer than would be expected given the scientific productivity of those communities. However, communities (Murcia, Balearic Islands, Asturias, Castile-Leon, Madrid), gave many more presentations than their productivity metrics would predict. Analysis of the 59 most frequent presenters (at 5 conferences or more) showed that 64.4% of them had published at least 20 articles and that 71.2% had an h-index of 5 or higher. The number of women on the program increased significantly between 1988 and 2017. Likewise, geographic diversity increased significantly (presentations from centers outside the local organizing area) as did the participation of hospitalbased emergency medicine specialists. CONCLUSION: SEMES conference programs have attracted significantly more presentations and presenters over the years. We also detected changes in descriptive characteristics. The analysis of those characteristics can help future SEMES conference planners to plan ways to correct aspects such as scarce geographic diversity, low international participation, and few women among presenters.

RESUMO

OBJECTIVES: To develop a multidimensional score to assess risk of death for patients of advanced age 180 days after their admission to short-stay units (SSUs). MATERIAL AND METHODS: Prospective, multicenter, observational and analytical study of a cohort of patients aged 75 years or older who were admitted to 5 Spanish SSUs between February 1 and April 30, 2014. We recorded demographic and clinical data as well as geriatric assessment scores. A multilevel logistic regression model was developed to identify independent factors associated with 180-day mortality. The model was used to construct a scale for scoring risk. RESULTS: Data for 593 patients with a mean (SD) age of 83.4 (5.9) years entered the model; 359 (60.7%) were women. Ninety-two patients (15.5%) died within 180 days of SSU admission. Factors included in the final risk score were age over 85 years (1 point), male sex (1), loss of appetite or weight loss in the 3 months before admission (1), acute confusional state (2), functional dependence for basic activities of daily living at admission (2), and pressure ulcers (2). Low risk was indicated by a score of 0 to 2 points, intermediate risk by 3 to 5 points, and high risk by 6 to 9 points. Mortality rates at 180 days in these 3 risk groups were 5%, 18%, and 54%, respectively. The area under the receiver operating characteristic curve for the model after boots trapping was 0.72 (95% CI, 0.65-0.78). CONCLUSION: The SSU score could be useful for stratifying risk of death within 6 months of SSU admission of older patients, so that type of care can be tailored to risk.

RESUMO

BACKGROUND: Various scores have been derived for the assessment of syncope patients in the emergency department (ED) but stay inconsistently validated. We aim to compare their performance to the one of a common, easy-to-use CHADS2 score. METHODS: We prospectively enrolled patients ≥ 40 years old presenting with syncope to the ED in a multicenter study. Early clinical judgment (ECJ) of the treating ED-physician regarding the probability of cardiac syncope was quantified. Two independent physicians adjudicated the final diagnosis after 1-year follow-up. Major cardiovascular events (MACE) and death were recorded during 2 years of follow-up. Nine scores were compared by their area under the receiver-operator characteristics curve (AUC) for death, MACE or the diagnosis of cardiac syncope. RESULTS: 1490 patients were available for score validation. The CHADS2-score presented a higher or equally high accuracy for death in the long- and short-term follow-up than other syncope-specific risk scores. This score also performed well for the prediction of MACE in the long- and short-term evaluation and stratified patients with accuracy comparative to OESIL, one of the best performing syncope-specific risk score. All scores performed poorly for diagnosing cardiac syncope when compared to the ECJ. CONCLUSIONS: The CHADS2-score performed comparably to more complicated syncope-specific risk scores in the prediction of death and MACE in ED syncope patients. While better tools incorporating biochemical and electrocardiographic markers are needed, this study suggests that the CHADS2-score is currently a good option to stratify risk in syncope patients in the ED.
