Comparative Study
Description and evaluation of a pilot physician-directed emergency medical services diversion control program.
To describe the characteristics and feasibility of a physician-directed ambulance destination-control program to reduce emergency department (ED) overcrowding, as measured by hospital ambulance diversion hours. ⋯ A voluntary, physician-directed destination-control program that directs EMS units to the ED most able to provide appropriate and timely care is feasible. Patients were redirected to maximize continuity of care and optimally use available emergency health care resources. This type of program may be effective in reducing overcrowding.

Little is known about whether emergency department (ED) patients or those who accompany them (visitors) are interested in smoking cessation. The authors hypothesized that several variables would be associated with stage of change, including nicotine dependence, self-efficacy, presence of a smoking-related illness, and anticipated cessation-related health improvement. ⋯ Because many disenfranchised Americans use the ED as a regular source of health care, increased attention to smoking in the ED setting holds tremendous public health potential. This study's results reinforce the validity of the stage-of-change model within the ED setting. Developers of ED-initiated interventions will have to consider the heterogeneity in stage of change when designing their treatments.

Patients presenting with chest pain or related symptoms suggestive of myocardial ischemia, without ST-segment elevation (NSTE) on their presenting electrocardiograms, often present a diagnostic challenge in the emergency department (ED). Prompt and accurate risk stratification to identify those patients with NSTE chest pain who are at highest risk for adverse events is essential, however, to optimal management. Although validated and used frequently in patients already enrolled in acute coronary syndrome trials, the Thrombolysis in Myocardial Infarction (TIMI) risk score never has been examined for its value in risk stratification in an all-comers, non-trial-based ED chest pain population. ⋯ The TIMI risk score may be a useful tool for risk stratification of ED patients with chest pain syndrome.

To determine the publication status and time to publication of randomized controlled trials (RCTs) that were presented at the Society for Academic Emergency Medicine (SAEM) meetings from 1995 to 2003. The impact of positive-outcome bias, time-lag bias, and gray literature bias also was assessed. ⋯ The proportion of emergency medicine RCT abstracts published is slightly lower than that for other biomedical specialties; however, biases reported by investigators in other biomedical areas do not appear to be as problematic in emergency medicine research. Differences between conclusions from abstracts and manuscripts must be considered when employing meeting abstracts as a source of evidence for future research or for systematic reviews in emergency medicine.

Comparative Study
Using queueing theory to increase the effectiveness of emergency department provider staffing.
Significant variation in emergency department (ED) patient arrival rates necessitates the adjustment of staffing patterns to optimize the timely care of patients. This study evaluated the effectiveness of a queueing model in identifying provider staffing patterns to reduce the fraction of patients who leave without being seen. ⋯ Timely access to a provider is a critical dimension of ED quality performance. In an environment in which EDs are often understaffed, analyses of arrival patterns and the use of queueing models can be extremely useful in identifying the most effective allocation of staff.
