RESUMO

OBJECTIVE: To analyse and compare 30-day mortality prognostic power of several biomarkers (C-reactive protein, procalcitonin, lactate and suPAR) in patients seen in emergency departments (ED) due to infections. Secondly, if these could improve the accuracy of systemic inflammatory response syndrome (SIRS) and quick Sepsis-related Organ Failure Assessment (qSOFA). METHODS: A prospective, observational and analytical study was carried out on patients who were treated in an ED of one of the eight participating hospitals. An assessment was made of 32 independent variables that could influence mortality at 30 days. They covered epidemiological, comorbidity, functional, clinical and analytical factors. RESULTS: The study included 347 consecutive patients, 54 (15.6%) of whom died within 30 days of visiting the ED. SUPAR has got the best biomarker area under the curve (AUC)-ROC to predict mortality at 30 days of 0.836 (95% CI: 0.765-0.907; P <.001) with a cut-off > 10 ng/mL who had a sensitivity of 70% and a specificity of 86%. The score qSOFA ≥ 2 had AUC-ROC of 0.707 (95% CI: 0.621-0.793; P < .001) with sensitivity of 53% and a specificity of 89%. The mixed model (suPAR > 10 ng/mL plus qSOFA ≥ 2) has improved the AUC-ROC to 0.853 [95% CI: 0.790-0.916; P < .001] with the best prognostic performance: sensitivity of 39% and a specificity of 97% with a negative predictive value of 90%. CONCLUSIONS: suPAR showed better performance for 30-day mortality prognostic power from several biomarkers in the patients seen in ED due to infections. Score qSOFA has better performance that SRIS and the mixed model (qSOFA ≥ 2 plus suPAR > 10 ng/mL) increased the ability of qSOFA.

RESUMO

OBJECTIVE: The aim of the study was to analyze predictive factors of bacteraemia in patients seen in the emergency department (ED) for an episode of infectious disease. METHODS: Observational, retrospective and descriptive analytical study of all blood cultures extracted in an ED in adult patients (≥ 18 years) seen in ED due to infec-tious disease from 1-1-2019 to 1-7-2019. The follow-up was carried out during 30 days. Thirty-eight variables for predicting bacteraemia were assessed. They covered epidemiological, comorbidity, functional, clinical and analytical factors. Univariate and multivariate logistic regression analysis was performed. RESULTS: A total of 1,425 blood cultures were finally enrolled in the study. Of those were considered true bacteremia 179 (12.6 %) and as negative blood cultures 1,246 (87.4 %). Amongst negatives, 1,130 (79.3%) without growth and 116 (8.1%) as contaminants blood cultures. Five variables were significantly associated with true bacteraemia: serum procalcitonin (PCT) ≥ 0.51 ng/ml [odds ratio (OR): 4.52; 95% confidence interval (CI): 4.20-4.84, P <.001], temperature > 38.3°C [OR:1.60; 95% CI:1.29-1.90, P <.001], systolic blood pressure (SBP) < 100 mmHg [OR:3.68; 95% CI:2.78-4.58, P <.001], septic shock [OR:2.96; 95% CI:1.78-4.13, P <.001] and malignancy [OR:1.73; 95% CI:1.27-2.20, P <.001]. CONCLUSIONS: Several factors evaluated in an initial assessment in the ED, including serum PCT, temperature, hypotension (with/without septic shock) and being malignancy, were found to predict true bacteraemia.
