RESUMO
OBJECTIVE: To analyse the changes in epidemiology, outpatient and emergency department clinical care, and outcomes of patients treated for acute heart failure (AHF) in Spanish hospital emergency departments (HEDs) between 2007 and 2014. METHOD: A multicentre cohort study was conducted that consecutively included patients with AHF diagnosed in 9HEDs during 4 periods (2007, 2009, 2011 and 2014). The study analysed the changes observed in 20 variables corresponding to baseline data, outpatient care and emergency care data and outcome data. RESULTS: A total of 4,845 patients were included. There were significant changes in 13 variables: there was an increase in patients older than 80years (2007/2014: 45.9%/55.4%; P<.001) and a decrease in severe functional dependence (28.2%/19.7%; P<.001). In terms of long-term outpatient care, there was an increased use of beta-blockers (44.6%/57.8%; P=.002) and aldosterone antagonists (26.6%/37.7%; P<.05) among patients with reduced ejection fraction and an increase use of echocardiography (42.8%/56.2%; P=.001). The use of digoxin decreased (25.4%/16.9%; P=.005). In terms of emergency care, there was an increase in requests for troponins (54.6%/61.9%; P<.001), natriuretic peptides (7.8%/48.5%; P<.001) and the use of noninvasive ventilation (3.2%/6.9%; P=.004). Requests for endovenous perfusion drugs decreased (diuretics: 21.3%/10.4%; P<.001; nitrates: 21.3%/17.5%; P=.001; vasopressors: 4.2%/1.5%; P<.001). Finally, discharges directly from the emergency department without hospitalization increased (20.0%/25.9%; P<.001), and emergency department readmissions at 30days decreased (27.3%/17.6%; P=.007). Hospital mortality and mortality at 30days did not change. CONCLUSIONS: Changes in outcomes were detected during a 7-year period in patients with AHF treated in HEDs, with care that was more in line with the clinical guidelines. There are, however, areas for improvement. There was a noteworthy increase in outpatient follow-up without hospitalisation and a reduction in HED readmissions.
RESUMO
OBJECTIVE: We determined the clinical-epidemiological characteristics and prognostic factors of early mortality and re-consultation in an elderly population attending the hospital emergency department (HED) for acute heart failure (AHF). PATIENTS AND METHODS: A prospective, observational, non interventional study including all the patients with AHF attended in the Spanish's HED. Two groups were defined: elderly (≥ 80 years) and controls (< 80 years). VARIABLES: demographic characteristics, comorbidity, degree of cardiac involvement, previous treatment, symptoms and signs of the AHF episode, precipitating factors, treatment in the HED and outcome. OUTCOME VARIABLES: mortality and re-consultation within 30 days. RESULTS: Of the 942 patients included, 455 of whom were elderly (48.3%). In this elderly population female sex, auricular fibrillation and a history of ictus and a poor functional status predominated. The type of ventricular dysfunction was unknown in 70%. No main differences in the presentation of AHF were found between the two groups. Mortality and re-consultation to the HED within 30 days were similar in both groups. While several factors were identified to be related to mortality or re-consultation in control group, in the elderly group it was more difficult to identify patients who will die or re-consult to the HED within the following 30 days. Only respiratory insufficiency on arrival to the HED was found to predict a greater probability of death (OR 3.55; CI95% 1.39-9.11). CONCLUSIONS: AHF in elderly patients presents some differential characteristics and, most importantly, it is more difficult to identify which of these patients will die or re-consult in the short-term.
