Few studies investigate the benefits of familiarity or continuity during physician-to-physician handoff of inpatients. Factors such as how recently physicians (MDs) have worked and successive days caring for patients increase continuity, and thus could lead to enhanced handoff efficiency. Evaluating the efficacy of MD scheduling to enhance continuity is currently subjective. ⋯ The increased HCS was associated with the MD qualitative assessment of enhanced continuity and efficiency after implanting a schedule change. The IP identified the potential for additional scheduling improvements.

Trauma is a major cause of death worldwide, with some 30% of deaths associated with hemorrhage. Rapid control of bleeding in such patients is thus an essential aspect of trauma care. ⋯ In this setting it may be increasingly difficult to demonstrate that any intervention can influence survival since the number of patients needed for sufficient power is so high and the duration needed for recruitment of the patients too long. In the present commentary, we reflect on how we can move forward in the management of severely bleeding trauma patients in the current environment.

Tobramycin is one of the components used for selective decontamination of the digestive tract (SDD), applied to prevent colonization and subsequent infections in critically ill patients. Tobramycin is administered in the oropharynx and gastrointestinal tract and is normally not absorbed. However, critical illness may convey gut barrier failure. The aim of the study was to assess the prevalence and amount of tobramycin leakage from the gut into the blood, to quantify tobramycin excretion in urine, and to determine the association of tobramycin leakage with markers of circulation, kidney function and other organ failure. ⋯ The majority of acute critically ill patients treated with enteral tobramycin as a component of SDD had traces of tobramycin in the blood, especially those with severe shock, inflammation and subsequent acute kidney injury, suggesting loss of gut barrier and decreased renal removal. Unexpectedly, urinary tobramycin was above the therapeutic trough level in half of the patients. Nephrotoxicity could not be demonstrated.

Nearly a decade since the introduction of therapeutic hypothermia to the ICU for cooling out-of-hospital cardiac arrest patients, key questions remain unanswered: when should cooling be initiated, how rapidly should the patient be cooled and using which device? The Time to Target Temperature study group provides important baseline data on the striking direct relationship between body temperature and survival from out-of-hospital cardiac arrest.

Magnesium sulfate for aneurysmal subarachnoid hemorrhage: the end of the road or more trials?
Delayed cerebral ischemia (DCI) is a feared complication and an important cause of poor outcome after aneurysmal subarachnoid hemorrhage (SAH). In the current study, Wong and colleagues performed a systematic review and meta-analysis of randomized controlled trials that investigated the efficacy of magnesium sulfate in patients with aneurysmal SAH. Outcome measures were DCI, cerebral infarction, and functional outcome 3 and 6 months after SAH. ⋯ Clinical deterioration due to DCI is more subject to inter-observer bias compared to cerebral infarction, which represents the ultimate outcome of the ischemic event. The Magnesium in Aneurysmal Subarachnoid Hemorrhage-II (MASH-II: ISRCTN68742385) phase III clinical trial nears completion. It aims to include 1,200 patients, and its results are urgently awaited.
