ReviewBedside Ultrasound in the Intensive Care Unit: Where Is the Evidence?
Interest in bedside ultrasound in the intensive care unit and emergency department has exploded in recent years. This interest is driven in part by the utility of ultrasound for procedural guidance. In most cases, enthusiasm outstrips current evidence. ⋯ Other possibilities include ventilator titration and guidance of diuresis. While the literature is more complicated, there is some early evidence that lung ultrasound may improve the diagnosis of dyspnea, although these results have not been well validated. Centers should avoid premature loss of equipoise and participate in studies of explicit protocols that incorporate ultrasound.

ReviewIntensivist Staffing: Evolving Challenges and Solutions.
Increases in critical care utilization related to aging of our population, static supplies of critical care specialists, and reduced availability of physicians in training to staff intensive care units (ICUs) have led many institutions to reevaluate their ICU prescribing provider staffing plans. The epidemiology of critical care staffing needs, regulations, requirements, standards, and professional society staffing recommendations are reviewed and the components of a prescribing provider staffing plan are described along with their costs. Factors that impact staffing costs including the availability of intensivist extenders, electronic support, and telemedicine tools that impact the efficiency of care delivery are evaluated in the context of staffing plan evaluation. Financial modeling is used to compare the costs of common prescribing provider staffing plans for typical referral medical center ICUs, community hospital ICUs, and rural health centers that care for the critically ill.

ReviewTo Trach or Not to Trach: Uncertainty in the Care of the Chronically Critically Ill.
The number of chronically critically ill patients requiring prolonged mechanical ventilation and receiving a tracheostomy is steadily increasing. Early tracheostomy in patients requiring prolonged mechanical ventilation has been proposed to decrease duration of mechanical ventilation and intensive care unit stay, reduce mortality, and improve patient comfort. However, these benefits have been difficult to demonstrate in clinical trials. ⋯ In chronically critically ill patients with poor prognosis, tracheostomy is unlikely to provide benefit and should only be pursued if it is consistent with the patient's values, goals, and preferences. In this setting, communication with patients and surrogates regarding tracheostomy and prognosis becomes paramount. For the foreseeable future, decisions surrounding tracheostomy will remain relevant and challenging.

ReviewProtocol-Based Care versus Individualized Management of Patients in the Intensive Care Unit.
The delivery of evidence-based care in the high-acuity environment of the intensive care unit can be challenging. In an effort to help turn guidelines and standards of care into consistent and uniform practice, physicians and hospitals turn toward protocol-based medical care. A protocol can help guide a practitioner to make correct interventions, at the right time, and in the proper order when managing a given disease. ⋯ In addition to the care the protocol delivers, it must overcome other barriers to gain acceptance. These include concerns about protocol usage among medical trainees, physician concern regarding loss of autonomy, and the ceiling effect protocol-driven care places on expert practitioners, among other concerns. The aim of this article is to critically appraise what it means for a protocol to be considered successful with an aim toward improving protocol design and implementation in the future.

ReviewHemodynamic Monitoring for the Evaluation and Treatment of Shock: What Is the Current State of the Art?
Hemodynamic monitoring has become a fundamental and ubiquitous, if not defining, aspect of critical care medicine practice. Modern monitoring techniques have changed significantly over the past few years and are now able to rapidly identify shock states earlier, define the etiology, and monitor the response to therapies. Many of these techniques are now minimally invasive or noninvasive. ⋯ Minimally invasive and noninvasive measure of arterial pressure and cardiac output are also possible and often remain as accurate as invasive measures. Importantly, such advanced monitoring provides the foundation for goal-directed therapies for the treatment of shock. When coupled with functional hemodynamic monitoring analyses, these measures markedly extend the diagnostic and therapeutic potential of all monitoring modalities by defining preload reserve, vasomotor tone, cardiac performance, and tissue perfusion.
