Hospital variation and temporal trends in palliative and end-of-life care in the ICU.
Although studies have shown regional and interhospital variability in the intensity of end-of-life care, few data are available assessing variability in specific aspects of palliative care in the ICU across hospitals or interhospital variability in family and nurse ratings of this care. Recently, relatively high family satisfaction with ICU end-of-life care has prompted speculation that ICU palliative care has improved over time, but temporal trends have not been documented. ⋯ We found significant interhospital variation in ratings and delivery of palliative care, consistent with prior studies showing variation in intensity of care at the end of life. We did not find evidence of temporal changes in most aspects of palliative care, family satisfaction, or nurse/family ratings of the quality of dying. With the possible exception of pain assessment, there is little evidence that the quality of palliative care has improved over the time period studied.

Multicenter StudyUse of therapeutic hypothermia after in-hospital cardiac arrest.
Formal guidelines recommend that therapeutic hypothermia be considered after in-hospital cardiac arrest. The rate of therapeutic hypothermia use after in-hospital cardiac arrest and details about its implementation are unknown. We aimed to determine the use of therapeutic hypothermia for adult in-hospital cardiac arrest, whether use has increased over time, and to identify factors associated with its use. ⋯ After in-hospital cardiac arrest, therapeutic hypothermia was used rarely. Once initiated, the target temperature was commonly not achieved. The frequency of use increased over time but remained low. Factors associated with therapeutic hypothermia use included patient age, time and location of occurrence, and type of hospital.

Lactate and venoarterial carbon dioxide difference/arterial-venous oxygen difference ratio, but not central venous oxygen saturation, predict increase in oxygen consumption in fluid responders.
During circulatory failure, the ultimate goal of treatments that increase cardiac output is to reduce tissue hypoxia. This can only occur if oxygen consumption depends on oxygen delivery. We compared the ability of central venous oxygen saturation and markers of anaerobic metabolism to predict whether a fluid-induced increase in oxygen delivery results in an increase in oxygen consumption. ⋯ In volume-responders, unlike markers of anaerobic metabolism, central venous oxygen saturation did not allow the prediction of whether a fluid-induced increase in oxygen delivery would result in an increase in oxygen consumption. This suggests that along with indicators of volume-responsiveness, the indicators of anaerobic metabolism should be considered instead of central venous oxygen saturation for starting hemodynamic resuscitation.
