RESUMO

Background: While clinical decision rules have been developed to evaluate exacerbations and decisions on hospitalisation and discharge in emergency departments (EDs) in patients with chronic obstructive pulmonary disease (COPD), these rules are not widely used in EDs. In this study, we compare the predictive efficacy of the Ottawa Chronic Obstructive Pulmonary Disease Risk Scale (OCRS) and the Dyspnea, Eosinopenia, Consolidation, Acidemia, and Atrial Fibrillation (DECAF) score in estimating the short-term poor outcome of patients in our ED with exacerbations of COPD. Methods: This single-centre prospective observational study was conducted over 6 months. Patients with acute exacerbations of COPD admitted to the ED during the study period were included in the study. A poor outcome was defined as any of the following: readmission and requiring hospitalisation within 14 days of discharge, requiring mechanical ventilation on the first admission, hospitalisation for longer than 14 days on the first admission, or death within 30 days. The sensitivity and specificity of the OCRS and the DECAF score for a poor outcome and for mortality were calculated. Results: Of the 385 patients who participated in the study, 85 were excluded based on the exclusion criteria. 66% of the patients were male, and the mean age was 70.15±10.36 years. A total of 20.7% of all patients (n=62) experienced poor outcomes. The sensitivity of an OCRS score <1 for predicting a poor outcome in patients was 96.8% (95% CI 88.8-99.6%) and the specificity was 18.5% (95% CI 13.8-24.0%). The sensitivity and specificity of an OCRS score <2 were 83.3% (95% CI 35.9-99.6%) and 65.5% (95% CI 59.6-70.7%), respectively. The sensitivity and specificity of a DECAF score <1 were 88.7% (95% CI 78.1-95.3%) and 34.5% (95% CI 28.4-40.9%), respectively. When the DECAF score was <2, sensitivity and specificity were 69.3% (95% CI 56.4-80.4%) and 74.8% (95% CI 68.8-80.2%), respectively. Conclusion: Our physicians achieved high specificity but low sensitivity in predicting a poor outcome. The OCRS is the more sensitive of the two tools, while the DECAF score is more specific in predicting a poor outcome when all threshold values are evaluated. While both tools may results in unnecessary hospitalisation, they can reduce the incidence of hospital discharge of patients with exacerbations of COPD who will develop poor outcomes in the ED.

RESUMO

BACKGROUND: The emergency physician should diagnose and treat the critical illnesses that cause syncope/presyncope in patients presenting to the emergency department (ED). Whole-body ultrasonography can detect the critical etiology of syncope with high diagnostic sensitivity. We aimed to reveal whether whole-body ultrasonography for syncope (WHOBUS-Syncope) protocol recognizes high-risk syncope patients and the effect of WHOBUS-Syncope protocol on the management of patients. METHOD: This is a prospective, cross-sectional study. Patients over the age of 18 years who presented to the ED with syncope or near syncope were included consecutively. Carotid, lung, cardiac, collapsibility of inferior vena cava, abdominal and compression ultrasonography of the lower extremity veins was performed among the WHOBUS-Syncope protocol. Frequency of abnormal sonographic findings associated with syncope/presyncope and requirement of critical intervention for abnormal sonographic findings were assessed. RESULTS: 152 patients were included in the study. The median age of the patients was 61.5 years (IQR: 41-71.8) and 52.6% were female. The most common (64.3%) abnormal sonographic finding was >50% collapse of vena cava inferior during inspiration. In addition, abnormal sonographic findings thought to cause syncope/presyncope were detected in 35.5% of the patients. Bolus fluid resuscitation were given in in 62 patients (40.8%) with increased inferior vena cava collapse. Critical interventions other than fluid resuscitation were performed for abnormal sonographic findings in 35 (23%) of the patients. Advanced age, increased heart rate and the presence of high-risk criteria in the 'European Society of Cardiology Guidelines for Syncope' were independent risk factors for detection of abnormal ultrasonographic findings related to syncope/presyncope. CONCLUSION: WHOBUS-Syncope protocol can be included in emergency practice as part of the standard evaluation in patients with syncope or presyncope presenting to the ED.
