Efficacy and safety of the computed tomography coronary angiography based approach for patients with acute chest pain at an emergency department: one month clinical follow-up study.

To evaluate the safety and efficacy of the computed tomography coronary angiography (CTCA) for evaluation of acute chest pain in real world population, we prospectively enrolled 296 patients with acute chest pain at emergency department (ED) from November 2005 to February 2007. The patients were grouped based on the clinical information and CTCA result. The patients with a low risk profile and no significant coronary stenosis (>50%) in CTCA were discharged immediately (Group 1, n=103).

The effects of an institutional care map on the admission rates and medical costs in women with acute pyelonephritis.

Objectives: There are no disposition guidelines for the management of acute pyelonephritis (APN) in women. Recent studies have demonstrated considerable variation in admission rates for women with APN. The authors evaluated the effect of a predetermined, written protocol for the management of APN on the admission rates and medical costs in adult women with APN.
