Prognostic Accuracy of Sepsis-3 Criteria for In-Hospital Mortality Among Patients With Suspected Infection Presenting to the Emergency Department.

Importance: An international task force recently redefined the concept of sepsis. This task force recommended the use of the quick Sequential Organ Failure Assessment (qSOFA) score instead of systemic inflammatory response syndrome (SIRS) criteria to identify patients at high risk of mortality. However, these new criteria have not been prospectively validated in some settings, and their added value in the emergency department remains unknown. Objective: To prospectively validate qSOFA as a mortality predictor and compare the performances of the new sepsis criteria to the previous ones. Design, Settings, and Participants: International prospective cohort study, conducted in France, Spain, Belgium, and Switzerland between May and June 2016. In the 30 participating emergency departments, for a 4-week period, consecutive patients who visited the emergency departments with suspected infection were included. All variables from previous and new definitions of sepsis were collected. Patients were followed up until hospital discharge or death. Exposures: Measurement of qSOFA, SOFA, and SIRS. Main Outcomes and Measures: In-hospital mortality. Results: Of 1088 patients screened, 879 were included in the analysis. Median age was 67 years (interquartile range, 47-81 years), 414 (47%) were women, and 379 (43%) had respiratory tract infection. Overall in-hospital mortality was 8%: 3% for patients with a qSOFA score lower than 2 vs 24% for those with qSOFA score of 2 or higher (absolute difference, 21%; 95% CI, 15%-26%). The qSOFA performed better than both SIRS and severe sepsis in predicting in-hospital mortality, with an area under the receiver operating curve (AUROC) of 0.80 (95% CI, 0.74-0.85) vs 0.65 (95% CI, 0.59-0.70) for both SIRS and severe sepsis (P < .001; incremental AUROC, 0.15; 95% CI, 0.09-0.22). The hazard ratio of qSOFA score for death was 6.2 (95% CI, 3.8-10.3) vs 3.5 (95% CI, 2.2-5.5) for severe sepsis. Conclusions and Relevance: Among patients presenting to the emergency department with suspected infection, the use of qSOFA resulted in greater prognostic accuracy for in-hospital mortality than did either SIRS or severe sepsis. These findings provide support for the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria in the emergency department setting.

Early variation of quick sequential organ failure assessment score to predict in-hospital mortality in emergency department patients with suspected infection.

BACKGROUND: The quick sequential organ failure assessment (qSOFA) score showed good prognostic performance in patients with suspicion of infection in the emergency department (ED). However, previous studies only assessed the performance of individual values of qSOFA during the ED stay. As this score may vary over short timeframes, the optimal time of measurement, and the prognostic value of its variation are unclear. The objective of the present study was to prospectively assess the prognostic value of the change in qSOFA over the first 3 h (ΔqSOFA = qSOFA at 3 h-qSOFA at inclusion). PATIENTS AND METHODS: This is an international prospective cohort study conducted in 17 EDs in France, Belgium, and Spain. From November 2016 to March 2017, patients with a suspected infection and a qSOFA score of 2 or higher were included and followed up until death or hospital discharge. qSOFA was measured at inclusion, 1 h and 3 h. Primary end point was in-hospital mortality, truncated at 28 days. RESULTS: Of 534 recruited patients, 512 were included in the analysis. The qSOFA was improved at 3 h (ΔqSOFA < 0) in 287 (55%) patients. Overall in-hospital mortality was 27%: 44% when ΔqSOFA greater than 0, 36% when ΔqSOFA = 0, and 18% when ΔqSOFA less than 0. A positive ΔqSOFA was independently associated with reduced in-hospital mortality (adjusted hazard ratio of 0.48, 95% confidence interval: 0.34-0.68). After modeling qSOFA kinetics in the first 3 h, there was a significant difference in adjusted slopes between patients who died and those who survived (0.15, 95% confidence interval: 0.09-0.22, P < 0.001). CONCLUSION: In patients with suspected infection presenting to the ED with a qSOFA of 2 or higher, the early change in qSOFA is a strong independent predictor of mortality.

Temporal trends in nitrate utilization for acute heart failure in elderly emergency patients: A single-centre observational study.

BACKGROUND: We previously conducted a pilot study that reported the safety of isosorbide dinitrate boluses for elderly emergency patients with acute heart failure syndrome. AIMS: To assess the temporal trend in the rate of elderly patients treated with isosorbide dinitrate, and to evaluate subsequent outcome differences. METHODS: This was a single-centre study. We compared patients aged>75 years who attended the emergency department with a primary diagnosis of acute pulmonary oedema in the years 2007 and 2014. The primary endpoint was the rate of patients who received isosorbide dinitrate boluses in the emergency department. Secondary endpoints included in-hospital mortality, need for intensive care and length of stay. RESULTS: We analysed 368 charts, 232 from patients included in 2014 (63%) and 136 in 2007 (37%). The mean age was 85±6 years in both groups. There was a significant rise in the rate of patients treated with isosorbide dinitrate between 2007 and 2014: 97 patients (42%) in 2014 vs. 24 patients (18%) in 2007 (P<0.01). Comparing the two periods, we report similar in-hospital mortality rates (8% vs. 11%; P=0.5), rates of admission to the intensive care unit (13% vs. 17%; P=0.3) and lengths of stay (10 days in both groups). CONCLUSION: We observed a significant rise in the rate of elderly patients treated with isosorbide dinitrate boluses for acute heart failure. However, we did not observe any significant improvement in outcomes.
