Multicenter Study
Patient-care time allocation by nurse practitioners and physician assistants in the intensive care unit.
Use of nurse practitioners and physician assistants ("affiliates") is increasing significantly in the intensive care unit (ICU). Despite this, few data exist on how affiliates allocate their time in the ICU. The purpose of this study was to understand the allocation of affiliate time into patient-care and non-patient-care activity, further dividing the time devoted to patient care into billable service and equally important but nonbillable care. ⋯ Approximately two thirds of an affiliate's shift is spent providing billable services to patients. Greater than 20% of each shift is spent providing equally important but not reimbursable patient care. Understanding how affiliates spend their time and what proportion of time is spent in billable activities can be used to plan the financial impact of staffing ICUs with affiliates.

Hyperosmolar therapy is the principal medical management strategy for elevated intracranial pressure. Mannitol has been the primary hyperosmolar agent for nearly a century and remains the de facto gold standard for medical management of intracranial hypertension. Over the past 25 years, however, hypertonic saline (HTS) has become a progressively more common alternative to mannitol, and several recent studies have suggested its relative superiority. ⋯ In the present article I make the case that current evidence supports HTS, not mannitol, as the better choice for gold-standard therapy for medical management of intracranial hypertension. This is accomplished first by examining the evidence on which the apparent designation of mannitol as the presumed gold-standard is based, then by reviewing the recent comparative efficacy data for HTS versus mannitol, and finally by discussing additional clinical considerations for appropriate designation of a gold-standard agent for hyperosmolar therapy. This assessment has important implications both for patient care and for clinical trial design.

The recent bus crash in Switzerland involving many children provides several lessons for the pre-hospital care community. The use of multiple helicopters that are capable of flying at night and that carry advanced medical pre-hospital teams undoubtedly saved lives following the tragedy. We describe the medical response to the incident and the lessons that can be learned for emergency medical services.

Standardization of data collection in severely injured trauma patients in order to find the best performance and practice has been an issue for more than 20 years. The incidence of trauma has decreased and outcomes have improved over the past decades. Trauma still remains an important public health problem, however, and is listed by the World Health Organization as a leading cause of death and disability. ⋯ In-depth analysis is currently only partially possible. The future of standardizing data collection in trauma looks bright. However, bridging and cross-linking is necessary to a great extent in the future.

Editorial Comment
Non-invasive mechanical ventilation in hematology patients: let's agree on several things first.
Acute respiratory failure is a dreaded and life-threatening event that represents the main reason for ICU admission. Respiratory events occur in up to 50% of hematology patients, including one-half of those admitted to the ICU. Mortality from acute respiratory failure in hematology patients depends on the patient's general status, acute respiratory failure etiology, need for mechanical ventilation and associated organ dysfunction. ⋯ There is growing concern about the safety of non-invasive mechanical ventilation to treat hypoxemic acute respiratory failure overall, but also in hematology patients. Prophylactic non-invasive mechanical ventilation in patients with acute respiratory failure but not respiratory distress seems to be effective in hematology patients with a reduced rate of intubation. However, curative non-invasive mechanical ventilation should be restricted to those patients with isolated respiratory failure, with fast improvement of respiratory distress under non-invasive mechanical ventilation, and with rapid switch to intubation to avoid deleterious delays in optimal invasive mechanical ventilation.
