In order to provide students with an experiential learning experience and understand the effect of a three-dimensional (3D) virtual learning environment in students' ill-structured problem-solving ability, the study designed a 3D virtual company (3DVC) for the participants to be a general manager to solve several complex problems for different departments. The study selected one class of busine...

AIM The effect of a gene-expression-based test on treatment of melanocytic neoplasms by dermatologists was evaluated. PATIENTS & METHODS Pathologists submitted diagnostically challenging melanocytic neoplasms to a clinical laboratory for testing accompanied by pretest surveys documenting the intended treatment recommendations. The actual treatment rendered by dermatologists was then documente...

BACKGROUND Positron emission tomography (PET) with 18-fluorodeoxyglucose (FDG) is a potentially useful but expensive test to diagnose solitary pulmonary nodules. OBJECTIVE To evaluate the cost-effectiveness of strategies for pulmonary nodule diagnosis and to specifically compare strategies that did and did not include FDG-PET. DESIGN Decision model. DATA SOURCES Accuracy and complications...

CONTEXT Experienced clinicians' gestalt is useful in estimating the pretest probability for pulmonary embolism and is complementary to diagnostic testing, such as lung scanning. However, it is unclear whether recently developed clinical prediction rules, using explicit features of clinical examination, are comparable with clinicians' gestalt. If so, clinical prediction rules would be powerful t...

DESCRIPTION Pulmonary embolism (PE) can be a severe disease and is difficult to diagnose, given its nonspecific signs and symptoms. Because of this, testing patients with suspected acute PE has increased dramatically. However, the overuse of some tests, particularly computed tomography (CT) and plasma d-dimer measurement, may not improve care while potentially leading to patient harm and unnece...
