Investigating Conflict in ICUs-Is the Clinicians' Perspective Enough?*.
Most studies have assessed conflict between clinicians and surrogate decision makers in ICUs from only clinicians' perspectives. It is unknown if surrogates' perceptions differ from clinicians'. We sought to determine the degree of agreement between physicians and surrogates about conflict and to identify predictors of physician-surrogate conflict. ⋯ Conflict between physicians and surrogates is common in ICUs. There is little agreement between physicians and surrogates about whether physician-surrogate conflict has occurred. Further work is needed to develop reliable and valid methods to assess conflict. In the interim, future studies should assess conflict from the perspective of both clinicians and surrogates.

Are Autopsy Findings Still Relevant to the Management of Critically Ill Patients in the Modern Era?
The purpose of this study was to determine the accuracy of clinical diagnoses compared to autopsy findings in critically ill patients in the current medical era. ⋯ We detected a lower rate of clinicopathological discrepancy in critically ill patients than previously reported. Potential reasons for such findings include advances in diagnostic techniques and the use of a more robust definition to classify diagnostic discrepancies. Autopsy can still identify discrepancies in diagnosis even in patients who have undergone appropriate investigations. Prospective research is required to accurately define discrepancy rates in the critically ill population and to identify the patient subgroups in whom autopsy will continue to yield valuable information.

Mechanical Ventilation During Cardiopulmonary Resuscitation With Intermittent Positive-Pressure Ventilation, Bilevel Ventilation, or Chest Compression Synchronized Ventilation in a Pig Model.
Mechanical ventilation with an automated ventilator is recommended during cardiopulmonary resuscitation with a secured airway. We investigated the influence of intermittent positive-pressure ventilation, bilevel ventilation, and the novel ventilator mode chest compression synchronized ventilation, a pressure-controlled ventilation triggered by each chest compression, on gas exchange, hemodynamics, and return of spontaneous circulation in a pig model. ⋯ Both intermittent positive-pressure ventilation and bilevel provided similar oxygenation and ventilation during cardiopulmonary resuscitation. Chest compression synchronized ventilation elicited the highest mean arterial pressure, best oxygenation, and a normal mixed venous pH during cardiopulmonary resuscitation.

The Medical Emergency Team Call: A Sentinel Event That Triggers Goals of Care Discussion.
Several studies have questioned the effectiveness of rapid-response systems when measured by outcomes such as decreased overall hospital mortality or cardiac arrest rates. We studied an alternative outcome of rapid-response system implementation, namely, its effect on goals of care and designation of do not resuscitate. ⋯ Implementation of a rapid-response system was associated with an increase in do-not-resuscitate order placement. As a sentinel event, medical emergency team activation and transfer to a critical care unit foster consideration of goals of care and frequently results in a transition to a palliative care strategy.

Withdrawal or withholding of life-sustaining therapies precedes most deaths in the modern ICU. As goals of care for critically ill patients change from curative to palliative, this transition often occurs abruptly, but a slower more staggered approach may also be used. One such approach is "no escalation of care", often the first step in this transition at the end-of-life. We aimed to determine the prevalence of no escalation of care designation for ICU decedents and identify which interventions are involved. ⋯ No escalation of care designation occurs in a significant proportion of ICU decedents shortly before death. Some interventions are more likely to be limited than others using a no escalation of care approach.
