Comparative Study
Measuring and forecasting emergency department crowding in real time.
We quantified the potential for monitoring current and near-future emergency department (ED) crowding by using 4 measures: the Emergency Department Work Index (EDWIN), the National Emergency Department Overcrowding Scale (NEDOCS), the Demand Value of the Real-time Emergency Analysis of Demand Indicators (READI), and the Work Score. ⋯ The EDWIN, the NEDOCS, and the Work Score monitor current ED crowding with high discriminatory power, although none of them exceeded the performance of occupancy level across the range of operating points. None of the measures provided substantial advance warning before crowding at low rates of false alarms.

Cyanide poisoning must be seriously considered in victims of smoke inhalation from enclosed space fires; it is also a credible terrorism threat agent. The treatment of cyanide poisoning is empiric because laboratory confirmation can take hours or days. Empiric treatment requires a safe and effective antidote that can be rapidly administered by either out-of-hospital or emergency department personnel. ⋯ The efficacy of sodium thiosulfate is based on individual case studies, and there are contradictory conclusions about efficacy in animal models. The onset of antidotal action of sodium thiosulfate may be too slow for it to be the only cyanide antidote for emergency use. Hydroxocobalamin is being developed for potential introduction in the United States and may represent a new option for emergency personnel in cases of suspected or confirmed cyanide poisoning in the out-of-hospital setting.

One of the latest market-based solutions to the rising costs and quality gaps in health care is pay for performance. Pay for performance is the use of financial incentives to promote the delivery of designated standards of care. Pay for performance represents a dramatic change in the reimbursement of providers, from fixed rates or fees, to variable compensation based on the quality of care. ⋯ I discuss the goals and structure of pay for performance plans and their limitations and potential consequences in the health care arena. A particular focus is provided on pay-for-performance initiatives affecting the emergency department either directly by contracting at the group level or indirectly through hospital reward programs. I also provide a strategy to guide constructive engagement by emergency physicians in the pay-for-performance movement.

Clinical Trial
Prospective study of hydroxocobalamin for acute cyanide poisoning in smoke inhalation.
To assess outcomes in patients treated with hydroxocobalamin at the fire scene or in the ICU for suspected smoke inhalation-associated cyanide poisoning. ⋯ Empiric administration of hydroxocobalamin was associated with survival among 67% of patients confirmed a posteriori to have had cyanide poisoning. Hydroxocobalamin was well tolerated irrespective of the presence of cyanide poisoning. Hydroxocobalamin appears to be safe for the out-of-hospital treatment of presumptive cyanide poisoning from smoke inhalation.

Concentrated aqueous solutions of hydroxocobalamin (OHCob) are administered intravenously for cyanide poisoning victims, many of whom also have concurrent smoke inhalation. Because of its intense light absorbance in visible wavelengths (absorption peak at 532 nm), we investigate potential interference effects of OHCob on total hemoglobin concentration (tHb), carboxyhemoglobin (COHb), methemoglobin (MetHb), and oxyhemoglobin (Hb-O2) cooximetry measurement values in blood. ⋯ The presence of OHCob in blood interferes with cooximetry measurements of COHb, MetHb, and Hb-O2. These effects need to be considered during OHCob treatment of cyanide poisoning, particularly in smoke inhalation victims with potential for concurrent carbon monoxide exposure, because it may lead to potentially erroneous reported COHb levels.
