The authors investigated whether models using time series methods can generate accurate short-term forecasts of emergency department (ED) bed occupancy, using traditional historical averages models as comparison. ⋯ Both a sinusoidal model with AR-structured error term and a seasonal ARIMA model were found to robustly forecast ED bed occupancy 4 and 12 hours in advance at three different EDs, without needing data input beyond bed occupancy in the preceding hours.

Multicenter Study
Potential impact of adjusting the threshold of the quantitative D-dimer based on pretest probability of acute pulmonary embolism.
The utility of D-dimer testing for suspected pulmonary embolism (PE) can be limited by test specificity. The authors tested if the threshold of the quantitative D-dimer can be varied according to pretest probability (PTP) of PE to increase specificity while maintaining a negative predictive value (NPV) of >99%. ⋯ This large multicenter observational sample demonstrates that emergency medicine clinicians currently order a D-dimer in the majority of patients tested for PE, including a large proportion with intermediate PTP and high PTP. Varying the D-dimer's cutoff according to PTP can increase specificity with no measurable decrease in NPV.

This before-after study investigated the association between an audit program and door-to-balloon times in patients with acute ST-elevation myocardial infarction (STEMI) and explored other factors associated with the door-to-balloon time. ⋯ The implementation of an audit program was associated with a significant reduction in door-to-balloon times among patients with acute STEMI. In addition, female patients, posterolateral wall infarction territory, and nonuse of glycoprotein IIb/IIIa inhibitor were associated with longer door-to-balloon times.

The objective was to determine the frequency of unsuspected or unacknowledged depressive symptoms among young adult emergency department (ED) patients. ⋯ There is a high prevalence of depressive symptoms in young adult ED patients. Young adults often do not recognize, or are reluctant to acknowledge, depressive symptoms. Specific patient characteristics may be useful in deciding which young adults should undergo ED screening for depression.

The primary objective of this study was to assess variables that residency applicants ranked as influential in making residency choices. The secondary objective was to determine if residents were satisfied with their residency choices. ⋯ The most influential factors in residency choice are institutional and residency director reputation and hospital facilities. Personal issues, such as recreational opportunities and spousal opinion, are also important, but are less influential. Significant geographic differences affecting residency choices exist, as do minor gender differences. A majority of residents were highly satisfied overall with their residency choices.
