RESUMO
BACKGROUND: Collaboration for the Diagnosis and Evaluation of Acute Coronary Syndrome (CoDE-ACS) is a validated clinical decision support tool that uses machine learning with or without serial cardiac troponin measurements at a flexible time point to calculate the probability of myocardial infarction (MI). How CoDE-ACS performs at different time points for serial measurement and compares with guideline-recommended diagnostic pathways that rely on fixed thresholds and time points is uncertain. METHODS: Patients with possible MI without ST-segment-elevation were enrolled at 12 sites in 5 countries and underwent serial high-sensitivity cardiac troponin I concentration measurement at 0, 1, and 2 hours. Diagnostic performance of the CoDE-ACS model at each time point was determined for index type 1 MI and the effectiveness of previously validated low- and high-probability scores compared with guideline-recommended European Society of Cardiology (ESC) 0/1-hour, ESC 0/2-hour, and High-STEACS (High-Sensitivity Troponin in the Evaluation of Patients With Suspected Acute Coronary Syndrome) pathways. RESULTS: In total, 4105 patients (mean age, 61 years [interquartile range, 50-74]; 32% women) were included, among whom 575 (14%) had type 1 MI. At presentation, CoDE-ACS identified 56% of patients as low probability, with a negative predictive value and sensitivity of 99.7% (95% CI, 99.5%-99.9%) and 99.0% (98.6%-99.2%), ruling out more patients than the ESC 0-hour and High-STEACS (25% and 35%) pathways. Incorporating a second cardiac troponin measurement, CoDE-ACS identified 65% or 68% of patients as low probability at 1 or 2 hours, for an identical negative predictive value of 99.7% (99.5%-99.9%); 19% or 18% as high probability, with a positive predictive value of 64.9% (63.5%-66.4%) and 68.8% (67.3%-70.1%); and 16% or 14% as intermediate probability. In comparison, after serial measurements, the ESC 0/1-hour, ESC 0/2-hour, and High-STEACS pathways identified 49%, 53%, and 71% of patients as low risk, with a negative predictive value of 100% (99.9%-100%), 100% (99.9%-100%), and 99.7% (99.5%-99.8%); and 20%, 19%, or 29% as high risk, with a positive predictive value of 61.5% (60.0%-63.0%), 65.8% (64.3%-67.2%), and 48.3% (46.8%-49.8%), resulting in 31%, 28%, or 0%, who require further observation in the emergency department, respectively. CONCLUSIONS: CoDE-ACS performs consistently irrespective of the timing of serial cardiac troponin measurement, identifying more patients as low probability with comparable performance to guideline-recommended pathways for MI. Whether care guided by probabilities can improve the early diagnosis of MI requires prospective evaluation. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT00470587.

INTRODUCTION: Mortality in emergency departments (EDs) is not well known. This study aimed to assess the impact of the first-wave pandemic on deaths accounted in the ED of older patients with COVID and non-COVID diseases. METHODS: We used data from the Emergency Department and Elderly Needs (EDEN) cohort (pre-COVID period) and from the EDEN-COVID cohort (COVID period) that included all patients ≥65 years seen in 52 Spanish EDs from April 1 to 7, 2019, and March 30 to April 5, 2020, respectively. We recorded patient characteristics and final destination at ED. We compared older patients in the pre-COVID period, with older patients with non-COVID and with COVID-19. ED-mortality (before discharge or hospitalization) is the prior outcome and is expressed as an adjusted odds ratio (aOR) with 95% interval confidence. RESULTS: We included 23,338 older patients from the pre-COVID period (aged 78.3 [8.1] years), 6,715 patients with non-COVID conditions (aged 78.9 [8.2] years) and 3,055 with COVID (aged 78.3 [8.3] years) from the COVID period. Compared to the older patients, pre-COVID period, patients with non-COVID and with COVID-19 were more often male, referred by a doctor and by ambulance, with more comorbidity and disability, dementia, nursing home, and more risk according to qSOFA, respectively (p < 0.001). Compared to the pre-COVID period, patients with non-COVID and with COVID-19 were more often to be hospitalized from ED (24.8% vs. 44.3% vs. 79.1%) and were more often to die in ED (0.6% vs. 1.2% vs. 2.2%), respectively (p < 0.001). Compared to the pre-COVID period, aOR for age, sex, comorbidity and disability, ED mortality in elderly patients cared in ED during the COVID period was 2.31 (95% confidence interval [CI]: 1.76-3.06), and 3.75 (95% CI: 2.77-5.07) for patients with COVID. By adding the variable qSOFA to the model, such OR were 1.59 (95% CI: 1.11-2.30) and 2.16 (95% CI: 1.47-3.17), respectively. CONCLUSIONS: During the early first pandemic wave of COVID-19, more complex and life-threatening older with COVID and non-COVID diseases were seen compared to the pre-COVID period. In addition, the need for hospitalization and the ED mortality doubled in non-COVID and tripled in COVID diagnosis. This increase in ED mortality is not only explained by the complexity or severity of the elderly patients but also because of the system's overload.

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.

AIMS: The optimal dose of diuretics and nitrates for acute heart failure treatment remains uncertain. This study aimed to assess the association between intravenous nitrates and loop diuretics doses within the initial 4â h of emergency department presentation and the number of days alive and out of hospital (NDAOH) through 30 days. METHODS: This was an ancillary study of the ELISABETH stepped-wedge cluster randomized trial that included 502 acute heart failure patients 75 years or older in 15 French emergency departments. The primary endpoint was the NDAOH at 30 days. The total dose of intravenous nitrates and loop diuretics administered in the initial 4â h were each categorized into three classes: 'no nitrate', '> 0-16', and '> 16â mg' for nitrates and '< 60', '60', and '> 60â mg' for diuretics. Secondary endpoints included 30-day mortality, 30-day hospital readmission, and hospital length of stay in patients alive at 30 days. Generalized linear mixed models were used to examine associations with the endpoints. RESULTS: Of 502 patients, the median age was 87 years, with 59% women. The median administered dose within the initial 4â h was 16â mg (5.0; 40.0) for nitrates and 40â mg (40.0; 80.0) for diuretics. The median NDAOH at 30 days was 19 (0.0-24.0). The adjusted ratios of the NDAOH were 0.88 [95% confidence interval (CI): 0.63-1.23] and 0.76 (95% CI: 0.58-1.00) for patients that received 60 and > 60â mg, respectively, compared with patients that received 40â mg or less of diuretics. Compared with patients who did not receive nitrates, the adjusted ratios of the NDAOH were 1.17 (95% CI: 0.82-1.67) and 1.45 (95% CI: 0.90-2.33) for patients who received 1-16 and > 16â mg, respectively. There was no significant association with any of the secondary endpoints. CONCLUSION: In this ancillary analysis, there was no significant association between different doses of diuretics and nitrates with the NDAOH at 30 days. Point estimates and CIs may suggest that the optimal doses are less than 60â mg of diuretics, and more than 16â mg of nitrates in the first 4â h.
RESUMO
BACKGROUND: The myocardial-ischaemic-injury-index (MI3) is a novel machine learning algorithm for the early diagnosis of type 1 non-ST-segment elevation myocardial infarction (NSTEMI). The performance of MI3, both when using early serial blood draws (eg, at 1 h or 2 h) and in direct comparison with guideline-recommended algorithms, remains unknown. Our aim was to externally validate MI3 and compare its performance with that of the European Society of Cardiology (ESC) 0/1h-algorithm. METHODS: In this secondary analysis of a multicentre international diagnostic cohort study, adult patients (age >18 years) presenting to the emergency department with symptoms suggestive of myocardial infarction were prospectively enrolled from April 21, 2006, to Feb 27, 2019 in 12 centres from five European countries (Switzerland, Spain, Italy, Poland, and Czech Republic). Patients were excluded if they presented with ST-segment-elevation myocardial infarction, did not have at least two serial high-sensitivity cardiac troponin I (hs-cTnI) measurements, or if the final diagnosis remained unclear. The final diagnosis was centrally adjudicated by two independent cardiologists using all available medical records, including serial hs-cTnI measurements and cardiac imaging. The primary outcome was type 1 NSTEMI. The performance of MI3 was directly compared with that of the ESC 0/1h-algorithm. FINDINGS: Among 6487 patients, (median age 61·0 years [IQR 49·0-73·0]; 2122 [33%] female and 4365 [67%] male), 882 (13·6%) patients had type 1 NSTEMI. The median time difference between the first and second hs-cTnI measurement was 60·0 mins (IQR 57·0-70·0). MI3 performance was very good, with an area under the receiver-operating-characteristic curve of 0·961 (95% CI 0·957 to 0·965) and a good overall calibration (intercept -0·09 [-0·2 to 0·02]; slope 1·02 [0·97 to 1·08]). The originally defined MI3 score of less than 1·6 identified 4186 (64·5%) patients as low probability of having a type 1 NSTEMI (sensitivity 99·1% [95% CI 98·2 to 99·5]; negative predictive value [NPV] 99·8% [95% CI 99·6 to 99·9]) and an MI3 score of 49·7 or more identified 915 (14·1%) patients as high probability of having a type 1 NSTEMI (specificity 95·0% [94·3 to 95·5]; positive predictive value [PPV] 69·1% [66·0-72·0]). The sensitivity and NPV of the ESC 0/1h-algorithm were higher than that of MI3 (difference for sensitivity 0·88% [0·19 to 1·60], p=0·0082; difference for NPV 0·18% [0·05 to 0·32], p=0·016), and the rule-out efficacy was higher for MI3 (11% difference, p<0·0001). Specificity and PPV for MI3 were superior (difference for specificity 3·80% [3·24 to 4·36], p<0·0001; difference for PPV 7·84% [5·86 to 9·97], p<0·0001), and the rule-in efficacy was higher for the ESC 0/1h-algorithm (5·4% difference, p<0·0001). INTERPRETATION: MI3 performs very well in diagnosing type 1 NSTEMI, demonstrating comparability to the ESC 0/1h-algorithm in an emergency department setting when using early serial blood draws.

OBJECTIVES: To evaluate the impact of specialized training for nurses on selective screening for undetected HIV infection in the emergency department. MATERIAL AND METHODS: The intervention group was comprised of 6 emergency departments that had been participating in a screening program (the "Urgències VIHgila" project) for at least 3 months. Nurses on all shifts attended training sessions that emphasized understanding the circumstances that should lead to suspicion of unidentified HIV infection and the need to order serology. Two studies were carried out: 1) a quasi-experimental pre-post study to compare the number of orders for HIV serology in each time period and measures of sensitivity, and 2) a case-control study to compare the changes made in the 6 hospitals where specialized training was provided (cases) vs 6 control hospitals in the HIV screening program where no training was given. RESULTS: A total of 280 HIV serologies were ordered for the 81015 patients (0.3%) attended during the period before training; 331 serologies were ordered for the 79620 patients in the period after training (0.4%). The relative increase in serologies was 20.3% (95% CI, 2.9% to 34.5%; P = .022). The relative increase in measures of sensitivity ranged between 19% and 39%, consistent with the main comparison. Serologies in the control group decreased between periods, from 0.9% to 0.8%, indicating a relative decrease of 15.7% (95% CI, -25.1% to -6.2%; P = .001). The absolute number of patients tested in the training group was 0.2% higher in the training hospitals (95% CI, 0.11% to 0.31%; P .001) than in the control hospitals. CONCLUSION: Training nurses to screen for undetected HIV infection in the emergency department increased the number of patients tested, according to the pre-post and case-control comparisons.
OBJETIVO: Evaluar el impacto de una formación específica para enfermería en el servicio urgencias (SU) sobre el despistaje selectivo de infección por VIH oculta. METODO: Participaron 6 SU adheridos al programa "Urgències VIHgila" con un mínimo de 3 meses y se realizaron sesiones formativas para los diferentes turnos. Las sesiones enfatizaban en qué circunstancias debía sospecharse infección oculta VIH y la necesidad de solicitar serología. Se realizaron dos estudios: 1) cuasiexperimental pre/post, que comparó la tasa de solicitudes VIH entre ambos periodos, con diversos análisis de sensibilidad; 2) caso-control, que comparó el cambio entre periodos de los 6 SU con formación (caso) con el cambio en otros 6 SU que no tuvieron formación (control). RESULTADOS: Se realizaron serologías de VIH a 280 de los 81.015 pacientes atendidos durante el periodo preintervención (0,3%) y a 331 de los 79.620 del periodo posintervención (0,4%). El incremento relativo fue del 20,3% (IC 95% de +2,9% a +34,5%; p = 0,022). Los análisis de sensibilidad mostraron incrementos relativos congruentes con el análisis principal (entre 19% y 39%). En el grupo control hubo descenso de solicitudes entre periodos, del 0,9% al 0,8% (descenso relativo del 15,7%, IC 95% de 25,1% a6,2%; p = 0,001). El grupo caso, en relación con el grupo control, tuvo un incremento absoluto de 0,2% (IC 95% de +0,11 a +0,31%, p 0,001) de pacientes testados. CONCLUSIONES: La formación de enfermería para despistaje de la infección VIH oculta en urgencias incrementa el número de pacientes investigados, tanto comparado con el periodo previo a la formación como comparado con SU sin formación específica para enfermería.

OBJECTIVE/BACKGROUND: Intravenous digoxin is still used in emergency departments (EDs) to treat patients with acute heart failure (AHF), especially in those with rapid atrial fibrillation. We investigated whether intravenous digoxin used to treat rapid atrial fibrillation in patients with AHF may influence mortality. METHODS: A secondary analysis of patients included in the Spanish EAHFE (Epidemiology of Acute Heart Failure in Emergency Departments) cohort, which includes patients diagnosed with AHF in 45 Spanish EDs. The relationships between age, estimated glomerular filtration rate, and potassium with 30-day mortality were investigated using restricted cubic spline models adjusted for relevant patient and episode variables. RESULTS: From the 19â 947 patients included, we analyzed 2194 patients with AHF and rapid atrial fibrillation that not receiving digoxin at home, divided according to whether they were or were not treated with intravenous digoxin in the ED. The median age of the patients was 82 years (interquartile range=76-87), 61.4% were women and 65.2% had previous episodes of atrial fibrillation. Digoxin and no digoxin groups were formed by 864 (39.4%) and 1330 (60.6%) patients, respectively. There were 191 deaths within the 30-day follow-up period (8.9%), with no differences between patients receiving or not receiving digoxin (8.5 vs. 9.1%, Pâ =â 0.636). Although analysis of restricted cubic spline curves showed that death was associated with advanced age, worse renal function, and hypokalemia and hyperkalemia, the use of intravenous digoxin did not interact with any of these relationships (Pâ =â 0.156 for age, Pâ =â 0.156 for estimated glomerular filtration rate, Pâ =â 0.429 for potassium). CONCLUSION: The use of intravenous digoxin in the ED was not associated with significant changes in 30-day mortality, which was confirmed irrespective of patient age or the existence of renal dysfunction or serum potassium disturbances.
RESUMO
OBJECTIVE: To investigate the association of the addition of thiazide diuretic on top of loop diuretic and standard of care with short-term outcomes of patients discharged after surviving an acute heart failure (AHF) episode. METHODS: This is a secondary analysis of 14,403 patients from three independent cohorts representing the main departments involved in AHF treatment for whom treatment at discharge was recorded and included loop diuretics. Patients were divided according to whether treatment included or not thiazide diuretics. Short-term outcomes consisted of 30-day all-cause mortality, hospitalization (with a separate analysis for hospitalization due to AHF or to other causes) and the combination of death and hospitalization. The association between thiazide diuretics on short-term outcomes was explored by Cox regression and expressed as hazard ratios (HR) with 95 % confidence intervals, which were adjusted for 18 patient-related variables and 9 additional drugs (aside from loop and thiazide diuretics) prescribed at discharge. RESULTS: The median age was 81 (interquartile range=73-86) years, 53 % were women, and patients were mainly discharged from the cardiology (42 %), internal medicine or geriatric department (29 %) and emergency department (19 %). There were 1,367 patients (9.5 %) discharged with thiazide and loop diuretics, while the rest (13,036; 90.5 %) were discharged with only loop diuretics on top of the remaining standard of care treatments. The combination of thiazide and loop diuretics showed a neutral effect on all outcomes: death (adjusted HR 1.149, 0.850-1.552), hospitalization (0.898, 0.770-1.048; hospitalization due to AHF 0.799, 0.599-1.065; hospitalization due to other causes 1.136, 0.756-1.708) and combined event (0.934, 0.811-1.076). CONCLUSION: The combination of thiazide and loop diuretics was not associated with changes in risk of death, hospitalization or a combination of both.
RESUMO
PURPOSE: Fear of falling (FOF) may result in activity restriction and deconditioning. The aim of the study was to identify factors associated with FOF in older patients and to investigate if FOF influenced long-term outcomes. METHODS: Multicentric, observational, prospective study including patients 65 years or older attending the emergency department (ED) after a fall. Demographical, patient- and fall-related features were recorded at the ED. FOF was assessed using a single question. The primary outcome was all-cause death. Secondary outcomes included new fall-related visit, fall-related hospitalisation, and admission to residential care. Logistic regression and Cox regression models were used for statistical analyses. RESULTS: Overall, 1464 patients were included (47.1% with FOF), followed for a median of 6.2 years (2.2-7.9). Seven variables (age, female sex, living alone, previous falls, sedative medications, urinary incontinence, and intrinsic cause of the fall) were directly associated with FOF whereas use of walking aids and living in residential care were inversely associated. After the index episode, 748 patients (51%) died (median 3.2 years), 677 (46.2%) had a new fall-related ED visit (median 1.7 years), 251 (17.1%) were hospitalised (median 2.8 years), and 197 (19.4%) were admitted to care (median 2.1 years). FOF was associated with death (HR 1.239, 95% CI 1.073-1.431), hospitalisation (HR 1.407, 95% CI 1.097-1.806) and institutionalisation (HR 1.578, 95% CI 1.192-2.088), but significance was lost after adjustment. CONCLUSION: FOF is a prevalent condition in older patients presenting to the ED after a fall. However, it was not associated with long-term outcomes. Future research is needed to understand the influence of FOF in maintenance of functional capacity or quality of life.
RESUMO
AIMS: We hypothesized that the current gold standard for risk stratification of patients with acute heart failure (AHF), the Multiple Estimation of risk based on the Emergency department Spanish Score In patients with AHF (MEESSI-AHF) risk score, can be further improved by adding systemic inflammation as quantified by C-reactive protein (CRP). METHODS AND RESULTS: In a prospective multicentre diagnostic study (BASEL V), AHF was centrally adjudicated by two independent cardiologists. The MEESSI-AHF risk score was calculated using an established reduced and recalibrated model containing 12 independent risk factors. Model extension was performed by refitting and adding CRP in the logistic regression model with 30-day mortality as binary outcome. Discrimination, calibration and clinical usefulness were used to assess the performance of the extended Multiple Estimation of risk based on the Emergency department Spanish Score In patients (MEESSI) model. Validation was performed in an independent, retrospective and single-centre AHF cohort. Among 1208 AHF patients with complete data allowing calculation of the recalibrated MEESSI and the extended MEESSI models, the prognostic accuracy for 30-day mortality of the extended MEESSI model (c-statistic 0.83, 95% confidence interval [CI] 0.79-0.87) was significantly higher compared to the recalibrated model (c-statistic 0.79, 95% CI 0.75-0.83, p = 0.013). The extended model allowed to stratify a higher percentage of patients into the lowest risk group compared to the recalibrated model (33.1% vs. 20.3%). Demonstrating a calibration plot's slope of 1.00 (95% CI 0.81-1.19) and an intercept of 0.0 (95% CI -0.22 to 0.22), the extended MEESSI model achieved excellent and improved calibration. Results were confirmed in the independent validation cohort (n = 575). CONCLUSIONS: Quantifying inflammation using CRP concentration provided incremental value in AHF risk stratification using the established MEESSI model.

OBJECTIVE: To describe other reasons for requesting HIV serology in emergency departments (ED) other than the 6 defined in the SEMES-GESIDA consensus document (DC-SEMES-GESIDA) and to analyze whether it would be efficient to include any of them in the future. METHODS: Review of all HIV serologies performed during 2 years in 20 Catalan EDs. Serologies requested for reasons not defined by the DC-SEMES-GESIDA were grouped by common conditions, the prevalence (IC95%) of seropositivity for each condition was calculated, and those whose 95% confidence lower limit was >0.1% were considered efficient. Sensitivity analysis considered that serology would have been performed on 20% of cases attended and the remaining 80% would have been seronegative. RESULTS: There were 8044 serologies performed for 248 conditions not recommended by DC-SEMES-GESIDA, in 17 there were seropositive, and in 12 the performance of HIV serology would be efficient. The highest prevalence of detection corresponded to patients from endemic countries (7.41%, 0.91-24.3), lymphopenia (4.76%, 0.12-23.8), plateletopenia (4.37%, 1.20-10.9), adenopathy (3.45%, 0.42-11.9), meningoencephalitis (3.12%, 0.38-10.8) and drug use (2.50%, 0.68-6.28). Sensitivity analysis confirmed efficiency in 6 of them: endemic country origin, plateletopenia, drug abuse, toxic syndrome, behavioral-confusional disorder-agitation and fever of unknown origin. CONCLUSION: The DC-SEMES-GESIDA targeted HIV screening strategy in the ED could efficiently include other circumstances not previously considered; the most cost-effective would be origin from an endemic country, plateletopenia, drug abuse, toxic syndrome, behavioral-confusional-agitation disorder and fever of unknown origin.
RESUMO
BACKGROUND: While the indication for noninvasive ventilation (NIV) in severely hypoxemic patients with acute heart failure (AHF) is often indicated and may improve clinical course, the benefit of early initiation before patient arrival to the emergency department (ED) remains unknown. OBJECTIVE: This study aimed to assess the impact of early initiation of NIV during emergency medical service (EMS) transportation on outcomes in patients with AHF. DESIGN: A secondary retrospective analysis of the EAHFE (Epidemiology of AHF in EDs) registry. SETTING: Fifty-three Spanish EDs. PARTICIPANTS: Patients with AHF transported by EMS physician-staffed ambulances who were treated with NIV at any time during of their emergency care were included and categorized into two groups based on the place of NIV initiation: prehospital (EMS group) or ED (ED group). OUTCOME MEASURES: Primary outcome was the composite of in-hospital mortality and 30-day postdischarge death, readmission to hospital or return visit to the ED due to AHF. Secondary outcomes included 30-day all-cause mortality after the index event (ED admission) and the different component of the composite primary endpoint considered individually. Multivariate logistic regressions were employed for analysis. RESULTS: Out of 2406 patients transported by EMS, 487 received NIV (EMS group: 31%; EMS group: 69%). Mean age was 79â years, 48% were women. The EMS group, characterized by younger age, more coronary artery disease, and less atrial fibrillation, received more prehospital treatments. The adjusted odds ratio (aOR) for composite endpoint was 0.66 (95% CI: 0.42-1.05). The aOR for secondary endpoints were 0.74 (95% CI: 0.38-1.45) for in-hospital mortality, 0.74 (95% CI: 0.40-1.37) for 30-day mortality, 0.70 (95% CI: 0.41-1.21) for 30-day postdischarge ED reconsultation, 0.80 (95% CI: 0.44-1.44) for 30-day postdischarge rehospitalization, and 0.72 (95% CI: 0.25-2.04) for 30-day postdischarge death. CONCLUSION: In this ancillary analysis, prehospital initiation of NIV in patients with AHF was not associated with a significant reduction in short-term outcomes. The large confidence intervals, however, may preclude significant conclusion, and all point estimates consistently pointed toward a potential benefit from early NIV initiation.
RESUMO
Sodium and fluid restriction has traditionally been advocated in patients with heart failure (HF) due to their sodium and water avid state. However, most evidence regarding the altered sodium handling, fluid homeostasis and congestion-related signs and symptoms in patients with HF originates from untreated patient cohorts and physiological investigations. Recent data challenge the beneficial role of dietary sodium and fluid restriction in HF. Consequently, the European Society of Cardiology HF guidelines have gradually downgraded these recommendations over time, now advising for the limitation of salt intake to no more than 5 g/day in patients with HF, while contemplating fluid restriction of 1.5-2 L/day only in selected patients. Therefore, the objective of this clinical consensus statement is to provide advice on fluid and sodium intake in patients with acute and chronic HF, based on contemporary evidence and expert opinion.

Digoxin is commonly used to treat acute heart failure (AHF), especially in patients with concurrent atrial fibrillation (AF). Nonetheless, there is little consensus about in which patients digoxin should be given, the proper time for digoxin initiation, and whether digoxin initiation is associated with improved outcomes. We investigated factors related to digoxin initiation after an episode of AHF and whether patients receiving digoxin presented better short-term outcomes. We analyzed digoxin-naïve AHF patients from a Spanish and Swiss database, who were dichotomized into cohorts based on their receipt of digoxin treatment at discharge. The relationship between digoxin initiation and 23 additional patient covariates, including chronic treatment, was investigated, as well as its association with 90-day combined adverse events (defined as all-cause death or AHF hospitalization). Of 13,105 patients (10,600/2505 from the Spanish/Swiss cohorts, respectively), the median (interquartile range) age was 83 (74.87) years, and 51% were women. Of these, 484 (3.7%) received digoxin at discharge, which was associated with AF, female sex, left ventricular ejection fraction (LVEF) < 50%, and coming from the Spanish cohort. Parameters inversely associated with receiving digoxin at discharge included some chronic treatments, diabetes mellitus (DM), and chronic kidney disease (CKD). Digoxin initiation was not association with 90-day adverse events, adjusted hazard ratio (aHR) = 0.939 (0.769-1.146), but there was an interaction for CKD, aHR = 1.390 (0.831-2.325) vs. 0.854 (0.682-1.183), p = 0.039, and for cohort pertinence, with higher risk in the Swiss cohort; aHR = 1.405 (0.827-2.386) vs. 0.862 (0.689-1.077), p = 0.046. Digoxin initiation after an AHF episode was more frequent in the Spanish cohort and was associated with certain patient characteristics (AF, female sex, reduced LVEF, no DM, no CKD), but had no effect on 90-day outcomes.
RESUMO
BACKGROUND: Point-of-care (POC) high-sensitivity cardiac troponin assays may further accelerate the diagnosis of myocardial infarction (MI). OBJECTIVES: This study sought to assess the clinical and analytical performance of the novel high-sensitivity cardiac troponin I (hs-cTnI)-SPINCHIP POC test. METHODS: Adult patients presenting with acute chest discomfort to the emergency department were enrolled in an international, diagnostic, multicenter study. The final diagnosis was centrally adjudicated by 2 independent cardiologists using all clinical information. We compared the discriminatory performance of hs-cTnI-SPINCHIP with current established central laboratory assays and derived an assay-specific hs-cTnI-SPINCHIP 0/1-hour algorithm. Secondary analyses included sample type comparisons (whole blood, fresh/frozen plasma, and capillary finger prick) and precision analysis. RESULTS: MI was the adjudicated final diagnosis in 214 (19%) of 1,102 patients. Area under the receiver-operating characteristic curve was 0.94 (95% CI: 0.92-0.95) for hs-cTnI-SPINCHIP vs 0.94 (95% CI: 0.92-0.95) for hs-cTnI-Architect (P = 0.907) and 0.93 (95% CI: 0.91-0.95) for high-sensitivity cardiac troponin T Elecsys (P = 0.305). A cutoff <7 ng/L at presentation (if chest pain onset was >3 hours) or <7 ng/L together with a 0/1-hour delta of <4 ng/L ruled out 51% with a sensitivity and negative predictive value of 100% (95% CI: 97.7%-100%) and 100% (95% CI: 99.0%-100%), respectively. A hs-cTnI-SPINCHIP concentration ≥36 ng/L or a 0/1-hour delta ≥11 ng/L ruled in 27% with a specificity and positive predictive value of 90.9% (95% CI: 88.3%-92.9%) and 72.9% (95% CI: 66.4%-78.6%), respectively. Bootstrap internal validation confirmed excellent diagnostic performance. High agreement was observed between different sample types. CONCLUSIONS: The SPINCHIP hs-cTnI POC test has very high diagnostic accuracy. Its assay-specific 0/1-hour algorithm achieved very high sensitivity/negative predictive value and specificity/positive predictive value for rule-out/in MI.

BACKGROUND: The use of urinary sodium to guide diuretics in acute heart failure is recommended by experts and the most recent European Society of Cardiology guidelines. However, there are limited data to support this recommendation. The ENACT-HF study (Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure) investigated the feasibility and efficacy of a standardized natriuresis-guided diuretic protocol in patients with acute heart failure and signs of volume overload. METHODS: ENACT-HF was an international, multicenter, open-label, pragmatic, 2-phase study, comparing the current standard of care of each center with a standardized diuretic protocol, including urinary sodium to guide therapy. The primary end point was natriuresis after 1 day. Secondary end points included cumulative natriuresis and diuresis after 2 days of treatment, length of stay, and in-hospital mortality. All end points were adjusted for baseline differences between both treatment arms. RESULTS: Four hundred one patients from 29 centers in 18 countries worldwide were included in the study. The natriuresis after 1 day was significantly higher in the protocol arm compared with the standard of care arm (282 versus 174 mmol; adjusted mean ratio, 1.64; P<0.001). After 2 days, the natriuresis remained higher in the protocol arm (538 versus 365 mmol; adjusted mean ratio, 1.52; P<0.001), with a significantly higher diuresis (5776 versus 4381 mL; adjusted mean ratio, 1.33; P<0.001). The protocol arm had a shorter length of stay (5.8 versus 7.0 days; adjusted mean ratio, 0.87; P=0.036). In-hospital mortality was low and did not significantly differ between the 2 arms (1.4% versus 2.0%; P=0.852). CONCLUSIONS: A standardized natriuresis-guided diuretic protocol to guide decongestion in acute heart failure was feasible, safe, and resulted in higher natriuresis and diuresis, as well as a shorter length of stay.

OBJECTIVES: To estimate the incidence of pneumonia diagnosis in elderly patients in Spanish emergency departments (ED), need for hospitalization, adverse events and predictive capacity of biomarkers commonly used in the ED. METHODS: Patients ≥65 years with pneumonia seen in 52 Spanish EDs were included. We recorded in-hospitaland 30-day mortality as adverse events, as well as intensive care unit (ICU) admission among hospitalizedpatients. Association of 10 predefined variables with adverse events was calculated and expressed as odds ratio (OR) with 95% confidence interval (CI), as well as predictive capacity of 5 commonly used biomarkers in the ED (leukocytes, hemoglobin, C-reactive protein, glucose, creatinine) was investigated using area under the receiver operating characteristic curve (AUC-ROC). RESULTS: 591 patients with pneumonia attended in the ED were included (annual incidence of 18,4 per 1000 inhabitants). A total of 78.0% were hospitalized. Overall, 30-day mortality was 14.2% and in-hospital mortality was 12.9%. Functional dependency was associated with both events (OR=4.453, 95%CI=2.361-8.400; and OR=3.497, 95%CI=1.578-7.750, respectively) as well as severe comorbidity (2.344, 1.363-4.030, and 2.463, 1.252-4.846, respectively). Admission to the ICU during hospitalization occurred in 3.5%, with no associated factors. The predictive capacity of biomarkers was only moderate for creatinine for ICU admission (AUC-ROC=0.702, 95% CI=0.536-0.869) and for leukocytes for post-discharge adverse event (0.669, 0.540-0.798). CONCLUSIONS: Pneumonia is a frequent diagnosis in elderly patients consulting in the ED. Their functional dependence and comorbidity is the factor most associated with adverse events. The biomarkers analyzed do not have a good predictive capacity for adverse events.
RESUMO
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.
RESUMO
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.
RESUMO
To investigate whether the timing of a previous hospital admission for acute heart failure (AHF) is a prognostic factor for AHF patients revisiting the emergency department (ED) in the subsequent 12-month follow-up. All ED AHF patients enrolled in the previously described EAHFE registry were stratified by the presence or absence of an AHF hospitalization admission in the prior 12 months. The primary outcome was 12-month all-cause mortality post ED visit. Secondary end points were hospital admission, prolonged hospitalization (> 7 days), mortality during hospitalization and a 90-day post-discharge adverse composite event (ACE) rate, defined as ED revisits due to AHF, hospitalizations due to AHF, or all-cause mortality. Outcomes were adjusted for baseline and AHF episode characteristics.Of 5,757 patients included, the median age was 84 years (IQR 77-88); 57% were women, and 3,759 (65.3%) had an AHF hospitalization in the previous 12 months. The 12-month mortality was 37% (41.7% vs. 28.3% p < 0.001), hospital admission was 76.1% (78.8% vs. 71.1% p < 0.001) ACE was 60.2% (65.1% vs. 50.5% p < 0.001). In the adjusted analysis, patients with AHF hospitalization in the prior 12 months had a higher mortality (HR = 1.41; 95% CI 1.27-1.56), 90-day ACE rate (HR = 1.45: 95% CI 1.32-1.59), and more hospital admissions (OR = 1.32; 95% CI 1.16-1.51), with shorter times since the previous hospitalization being related to the outcomes analyzed. One-year mortality, adverse events at 90 days, and readmission rates are increased in ED AHF patients previously admitted within the last 12 months.
