We conduct a prospective independent validation of the San Francisco Syncope Rule to identify emergency department (ED) syncope patients with short-term serious outcomes. ⋯ In this independent validation study, sensitivity and negative likelihood ratio of the San Francisco Syncope Rule were substantially lower than reported in the original studies and suggest that the rule has limited generalizability.

The rise in emergency department (ED) use in the United States is frequently attributed to increased visits by the uninsured. We determine whether insurance status is associated with the increase in ED visits. ⋯ The rise in ED visits between 1996 and 2003 cannot be primarily attributed to the uninsured. Major contributors to increasing ED utilization appear to be disproportionate increases in use by nonpoor persons and by persons whose usual source of care is a physician's office.

To develop a discrete event simulation of emergency department (ED) patient flow for the purpose of forecasting near-future operating conditions and to validate the forecasts with several measures of ED crowding. ⋯ By modeling patient flow, rather than operational summary variables, our simulation forecasts several measures of near-future ED crowding, with various degrees of good performance.

A 54-year-old man with an inferior vena cava filter in situ presented to the emergency department (ED) by emergency medical services, with acute onset of severe abdominal, lower back, and leg pain. He had fallen from a ladder 3 days before admission. An abdominal computed tomography scan revealed a large retroperitoneal hematoma and evidence of occlusive thrombus in the inferior vena cava, extending beyond the inferior vena cava filter. ⋯ The patient underwent bilateral fasciotomies of the lower extremities within 3 hours. Postoperatively, he developed extensive tissue necrosis and gangrene, requiring bilateral above-the-knee amputations, and acute renal failure associated with severe rhabdomyolysis, requiring hemodialysis. This case highlights the importance of prompt recognition and treatment of inferior vena cava filter thrombosis.
