Comparative Study
Forecasting daily patient volumes in the emergency department.
Shifts in the supply of and demand for emergency department (ED) resources make the efficient allocation of ED resources increasingly important. Forecasting is a vital activity that guides decision-making in many areas of economic, industrial, and scientific planning, but has gained little traction in the health care industry. There are few studies that explore the use of forecasting methods to predict patient volumes in the ED. ⋯ This study confirms the widely held belief that daily demand for ED services is characterized by seasonal and weekly patterns. The authors compared several time series forecasting methods to a benchmark multiple linear regression model. The results suggest that the existing methodology proposed in the literature, multiple linear regression based on calendar variables, is a reasonable approach to forecasting daily patient volumes in the ED. However, the authors conclude that regression-based models that incorporate calendar variables, account for site-specific special-day effects, and allow for residual autocorrelation provide a more appropriate, informative, and consistently accurate approach to forecasting daily ED patient volumes.

The Centers for Disease Control and Prevention (CDC) recommends routine human immunodeficiency virus (HIV) screening of emergency department (ED) patients aged 13 to 64 years. The study objectives were to determine the accessibility of rapid HIV testing in academic EDs, to identify factors that influence an ED's adoption of testing, and to describe current HIV testing practices. ⋯ Most academic EDs now offer rapid HIV testing (57%), but few use it in situations other than occupational exposure. Less than half of academic EDs expect to implement CDC guidelines regarding routine screening within the next few years. The authors identified facility characteristics (e.g., counseling, ability to refer) that may influence adoption of rapid HIV testing.

Comparative Study
Comparison of pediatric emergency physicians' and surgeons' evaluation and diagnosis of appendicitis.
To compare the interexaminer reliability and ability to predict appendicitis between pediatric emergency physicians (EPs) and senior surgical residents. ⋯ Pediatric EPs and senior surgical residents elicit historical findings from patients with suspected appendicitis with a greater degree of similarity than physical examination findings, which exhibit a wide degree of variability. Pediatric EPs and senior surgical residents do not differ in their ability to clinically predict appendicitis. These findings may be helpful in developing institutional management protocols.

One of the first stages in the development of new clinical decision rules (CDRs) is determination of need. This study examined the clinical priorities of emergency physicians (EPs) working in Australasia, Canada, the United Kingdom, and the United States for the development of future CDRs. ⋯ This international survey identified the sampled EPs' priorities for the future development of CDRs. The top priority overall was investigation of the febrile child < 36 months. These results will be valuable to researchers for future development of CDRs in EM that are relevant internationally.
