Quick sequential organ failure assessment versus systemic inflammatory response syndrome criteria for emergency department patients with suspected infection.

Previous studies have shown inconsistent prognostic accuracy for mortality with both quick sequential organ failure assessment (qSOFA) and the systemic inflammatory response syndrome (SIRS) criteria. We aimed to validate the accuracy of qSOFA and the SIRS criteria for predicting in-hospital mortality in patients with suspected infection in the emergency department. A prospective study was conducted including participants with suspected infection who were hospitalised or died in 34 emergency departments in Japan. Prognostic accuracy of qSOFA and SIRS criteria for in-hospital mortality was assessed by the area under the receiver operating characteristic (AUROC) curve. Of the 1060 participants, 402 (37.9%) and 915 (86.3%) had qSOFA ≥ 2 and SIRS criteria ≥ 2 (given thresholds), respectively, and there were 157 (14.8%) in-hospital deaths. Greater accuracy for in-hospital mortality was shown with qSOFA than with the SIRS criteria (AUROC: 0.64 versus 0.52, difference + 0.13, 95% CI [+ 0.07, + 0.18]). Sensitivity and specificity for predicting in-hospital mortality at the given thresholds were 0.55 and 0.65 based on qSOFA and 0.88 and 0.14 based on SIRS criteria, respectively. To predict in-hospital mortality in patients visiting to the emergency department with suspected infection, qSOFA was demonstrated to be modestly more accurate than the SIRS criteria albeit insufficiently sensitive.Clinical Trial Registration: The study was pre-registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN000027258).

Successful weaning from veno-arterial ECMO and Impella2.5 by veno-venous and arterial ECMO (v-ECPELLA) for a patient with acute myocardial infarction complicated by severe lung injury.

The Impella™ (Abiomed, Danvers, MA, USA) is a percutaneous left ventricular assist device and is concurrently used with veno-arterial extracorporeal membrane oxygenation (VA ECMO). However, concomitantly using these two devices makes identifying the mixed zone of two opposite blood flows difficult. We report the case of an 80-year-old man with ST-elevation myocardial infarction and cardiopulmonary arrest. Emergent coronary angiography showed 99% stenosis in the left main trunk. A drug-eluting stent was placed under support of VA ECMO and the Impella2.5 for cardiogenic shock. During this support, antegrade deoxygenated blood enhanced by the Impella was sent to the right radial artery. Inadequate oxygenated blood was delivered through the native lung, which was damaged by cardiopulmonary resuscitation. We decided to convert to veno-venous and arterial ECMO (V-VA ECMO) using additional venous cannulation as drainage. Returned oxygenated blood was sent to the inferior vena cava and femoral artery bilaterally for maintaining oxygenation in the pulmonary artery. In V-VA ECMO and the Impella (v-ECPELLA), we attempted weaning from VA ECMO by only clamping VA cannulation and switching to veno-venous ECMO. We restored the setting to VA ECMO after assessment of the systemic circulation. We successfully managed and weaned our patient from simultaneous use of VA ECMO and the Impella2.5 by using v-ECPELLA. .

Clinical characteristics of patients hospitalized for acute heart failure according to hospital arrival timing.

BACKGROUND: Whether clinical characteristics and outcomes in patients suffering acute heart failure (AHF) vary according to the timing of hospital arrival is unclear. We aimed to evaluate differences between subjects presenting in the daytime and nighttime. METHODS: A total of 679 patients with AHF were examined, classified into the two groups from the viewpoint of hospital arrival period into daytime (n=370; 8am-6pm) and nighttime (n=309; 6pm-8am). RESULTS: The prevalence of malnutrition and longer pre-hospital delay (≥48h) were greater, whereas a previous history of myocardial infarction, proportion of arrival by ambulance, and the frequency of New York Heart Association class IV symptoms, as well as systolic and diastolic blood pressure, and heart rate were lower in subjects presenting in the daytime. Patients with malnutrition defined as 5≥of the Controlling Nutrition Status scores demonstrate a longer pre-hospital delay compared to those without (34.2% vs. 19.9%, p<0.05). There was no significant difference in the 30-day outcomes but length of stay was significantly longer in subjects presenting in the daytime than in the nighttime. Multivariable logistic regression analysis revealed that systolic blood pressure, malnutrition, and chronic kidney disease were significantly related to prolonged length of stay. CONCLUSIONS: Our present results suggest that patients with AHF who present in the daytime may have higher rate of malnutrition status and lower systolic blood pressure compared to those presenting in the nighttime.
