Understanding variations in pediatric asthma care processes in the emergency department using visual analytics.

Health care delivery processes consist of complex activity sequences spanning organizational, spatial, and temporal boundaries. Care is human-directed so these processes can have wide variations in cost, quality, and outcome making systemic care process analysis, conformance testing, and improvement challenging. We designed and developed an interactive visual analytic process exploration and discovery tool and used it to explore clinical data from 5784 pediatric asthma emergency department patients.

Renal stones: evolving epidemiology and management.

The incidence of renal stones in adults has increased significantly over time. Although published evidence is somewhat limited, during the last 10 years, there have been reports of 4-fold increase in the number of children evaluated for nephrolithiasis, and of those, a 7-fold increase in diagnosis of stone disease. The etiology of stone formation has shifted over time, with a transition from infectious causes to metabolic causes.
