Several hospitals have been developing programmes for organ donation after cardiac death. Such programmes offer options for organ donation to patients who do not meet brain-death criteria but wish to donate their organs after withdrawal of life-support. These programmes also increase the available organ pool at a time when demand exceeds supply. ⋯ Donation after cardiac death clearly carries a number of important ethical issues with it. In the present issue of Critical Care two established groups debate the ethical acceptability of using medications/interventions in potential organ donors for the sole purpose of making the organs more viable. Such debates will be an increasingly common component of intensivists' future practice.

The aim of the study was to assess the influence of annual volume and factors related to intensive care unit (ICU) organization on in-hospital mortality among patients admitted to the ICU with severe sepsis. ⋯ A larger annual volume of patients with severe sepsis admitted to Dutch ICUs is associated with lower in-hospital mortality in this patient group. The presence of a MCU as a step-down facility is associated with greater in-hospital mortality. No other significant associations between in-hospital mortality and factors related to ICU organization were found.

In 2006, Critical Care provided important and clinically relevant research data in the field of multiple organ failure, sepsis, and shock. This review summarizes the results of the experimental studies and clinical trials and discusses them in the context of the relevant scientific and clinical background.

Review
Clinical review: timing and dose of continuous renal replacement therapy in acute kidney injury.
The optimal management of renal replacement therapy (RRT) in acute kidney injury (AKI) remains uncertain. Although it is well accepted that initiation of RRT in patients with progressive azotemia prior to the development of overt uremic manifestations is associated with improved survival, whether there is benefit to even earlier initiation of therapy is uncertain. ⋯ Several studies have suggested that more intensive delivery of CRRT during AKI is associated with improved survival, although results of trials have been inconsistent. Two large multicenter randomized clinical trials addressing this question are currently underway and should provide more definitive data within the next two years.

Multicenter Study
The impact of the introduction of critical care outreach services in England: a multicentre interrupted time-series analysis.
Critical care outreach services (CCOS) have been widely introduced in England with little rigorous evaluation. We undertook a multicentre interrupted time-series analysis of the impact of CCOS, as characterised by the case mix, outcome and activity of admissions to adult, general critical care units in England. ⋯ The observational nature of the study limits its ability to infer causality. Although associations were observed with characteristics of patients admitted to critical care units, there was no clear evidence that CCOS have a big impact on the outcomes of these patients, or for characteristics of what should form the optimal CCOS.
