To review the current literature on the effects of ambulance diversion (AD). ⋯ Despite its common use, there is a relative paucity of studies on the effects of AD. Further research into these effects should be performed so that we may understand the role of AD in the health system.

To determine if a ventilator available in an emergency department could quickly be modified to provide ventilation for four adults simultaneously. ⋯ A single ventilator may be quickly modified to ventilate four simulated adults for a limited time. The volumes delivered in this simulation should be able to sustain four 70-kg individuals. While further study is necessary, this pilot study suggests significant potential for the expanded use of a single ventilator during cases of disaster surge involving multiple casualties with respiratory failure.

This article reviews what is known about daily emergency department (ED) surge and ED surge capacity and illustrates its potential relevance during a catastrophic event. Daily ED surge is a sudden increase in the demand for ED services. There is no well-accepted, objective measure of daily ED surge. ⋯ A multidimensional measure is needed that reflects both the core components and their relative contribution to ED surge capacity. Although many types of factors may influence ED surge capacity, relatively little formal research has been conducted in this area. A better understanding of daily ED surge capacity and influencing factors will improve our ability to simulate the potential impact that different types of catastrophic events may have on the surge capacity of hospital EDs nationwide.

The 2006 Academic Emergency Medicine Consensus Conference discussed key concepts within the field of surge capacity. Within the breakout session on research priorities, experts in disaster medicine and other related fields used a structured nominal-group process to delineate five critical areas of research. Of the 14 potential areas of discovery identified by the group, the top five were the following: 1) defining criteria and methods for decision making regarding allocation of scarce resources, 2) determining effective triage protocols, 3) determining key decision makers for surge-capacity planning and means to evaluate response efficacy (e.g., incident command), 4) developing effective communication and information-sharing strategies (situational awareness) for public-health decision support, and 5) developing methods and evaluations for meeting workforce needs. Five working groups were formed to consider the above areas and to devise sample research questions that were refined further by the entire group of participants.

This report reflects the proceedings of a breakout session, "Surge Capacity: Defining Concepts," at the 2006 Academic Emergency Medicine Consensus Conference, "Science of Surge Capacity." Although there are several general descriptions of surge capacity in the literature, there is no universally accepted standard definition specifying the various components. Thus, the objectives of this breakout session were to better delineate the components of surge capacity and to outline the key considerations when planning for surge capacity. Participants were from diverse backgrounds and included academic and community emergency physicians, economists, hospital administrators, and experts in mathematical modeling. ⋯ The focus on enhancing surge capacity during a catastrophic event will be to increase patient-care capacity, rather than on increasing things, such as beds and medical supplies. Although there are similarities between daily surge and disaster surge, during a disaster, the goal shifts from the day-to-day operational focus on optimizing outcomes for the individual patient to optimizing those for a population. Other key considerations in defining surge capacity include psychosocial behavioral issues, convergent volunteerism, the need for special expertise and supplies, development of a standard of care appropriate for a specific situation, and standardization of a universal metric for surge capacity.
