Trends in the incidence and mortality of patients with community-acquired septic shock 2003-2016.

PURPOSE: To evaluate the incidence and mortality of adult patients with community-acquired septic shock (CASS) and the influence of source control (SC) and other risk factors on the outcome. MATERIAL AND METHODS: The study included patients with CASS admitted to the ICU at a university hospital (2003-2016). Multivariate analyses were performed to identify risk factors of ICU mortality. RESULTS: A total of 625 patients were included. The incidence showed an average annual increase of 4.9% and the mortality an average annual decrease of 1.4%. The patients who required SC showed a lower mortality (20.4%) than patients who did not require SC (31.3%) (p = 0.002). However, the evolution in mortality was different: Mortality decreased in patients who did not require SC (from 56.3% to 20%; p = 0.02), but did not differ in those who required SC (from 21.4% to 27.6%; p = 0.43). In the multivariate analysis, severity at admission, age, alcoholism, cirrhosis, ARDS, neutropenia and thrombocytopenia were associated with worse outcome, whereas appropriate antibiotic treatment and adequate SC were independently associated with better survival. CONCLUSIONS: The incidence of CASS increased and the ICU mortality decreased during the study period. The mortality was mainly due to a decrease in mortality in infections not requiring SC.

The fully automatic external cardioverter defibrillator: reality of a new meaningful scenario for in-hospital cardiac arrests.

Sudden cardiac death is an unresolved problem which causes significant mortality and morbidity in both the community and in-hospital setting. Cardiac arrest is often caused by ventricular tachyarrhythmias which may be mostly interrupted by cardioversion or defibrillation. The single most critical factor for survival is the response time. Over the last 30 years, there have been virtually no procedural changes in the way hospitals address in-hospital resuscitation. A unique device has been developed that eliminates human intervention and assures defibrillation therapy is administered in seconds. This is accomplished with a fully automatic, external bedside monitor defibrillator designed to be prophylactically attached to hospitalized patients at risk of ventricular tachyarrhythmia. The safety and efficacy of the device has been demonstrated in multicenter US and European trials. Thus, this device allows a new scenario which may increase survival and enables meaningful redistribution of health resources.
