Outcome prediction is important both in clinical and administrative intensive care unit (ICU) management.¹ Although outcome prediction and measurement should not be the only measure of ICU performance, outcome prediction can be usefully applied to monitor the performance of an individual ICU and possibly to compare ICUs. Outcome prediction can also be useful in providing information on likely patient outcomes for relatives of critically ill patients and potentially for therapeutic decision making and guiding resource allocation. Outcome prediction models currently available have not been validated for use in directing individual patient management.²

Weaning covers the entire process of liberating the patient from mechanical support and from the endotracheal tube. Many controversial questions remain concerning the best methods for conducting this process. An International Consensus Conference was held in April 2005 to provide recommendations regarding the management of this process. An 11-member international jury answered five pre-defined questions. 1) What is known about the epidemiology of weaning problems? 2) What is the pathophysiology of weaning failure? 3) What is the usual process of initial weaning from the ventilator? 4) Is there a role for different ventilator modes in more difficult weaning? 5) How should patients with prolonged weaning failure be managed?The main recommendations were as follows. 1) Patients should be categorised into three groups based on the difficulty and duration of the weaning process. 2) Weaning should be considered as early as possible. 3) A spontaneous breathing trial is the major diagnostic test to determine whether patients can be successfully extubated. 4) The initial trial should last 30 min and consist of either T-tube breathing or low levels of pressure support. 5) Pressure support or assist–control ventilation modes should be favoured in patients failing an initial trial/trials. 6) Noninvasive ventilation techniques should be considered in selected patients to shorten the duration of intubation but should not be routinely used as a tool for extubation failure.

Both dopamine and norepinephrine are recommended as first-line vasopressor agents in the treatment of shock. There is a continuing controversy about whether one agent is superior to the other.

The aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe. This was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries. Data on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge. The results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe. EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events.

Beta-blockers may have a negative impact on survival in patients with cirrhosis and refractory ascites. The aim of this study was to evaluate the effect of the administration of beta-blockers on long-term survival in patients with cirrhosis and refractory ascites. We performed a single-center, observational, case-only, prospective study of patients with cirrhosis and refractory ascites who did or did not receive beta-blockers for the prevention of gastrointestinal bleeding; 151 patients were included. The mean Model for End-Stage Liver Disease score was 18.8 ± 4.1. All patients regularly underwent large-volume paracentesis and intravenous albumin administration. Seventy-seven patients (51%) were treated with propranolol (113 ± 46 mg/day). The median follow-up for the whole group was 8 months. The median survival time was 10 months [95% confidence interval (CI) = 8-12 months]. The probability of survival at 1 year was 41% (95% CI = 33%-49%). The clinical characteristics and laboratory values at enrolment were not significantly different between patients who were receiving propranolol and those who were not. The median survival time was 20.0 months (95% CI = 4.8-35.2 months) in patients not treated with propranolol and 5.0 months (95% CI = 3.5-6.5 months) in those treated with propranolol ( P = 0.0001). The 1-year probability of survival was significantly lower in patients who received propranolol [19% (95% CI = 9%-29%)] versus those who did not [64% (95% CI = 52%-76%), P < 0.0001]. The independent variables of mortality were Child-Pugh class C, hyponatremia and renal failure as causes of refractory ascites, and beta-blocker therapy. Conclusion: The use of beta-blockers is associated with poor survival in patients with refractory ascites. These results suggest that beta-blockers should be contraindicated in these patients.
