Geographic modeling to quantify the impact of primary and comprehensive stroke center destination policies.
The purpose of this study was to evaluate the impact of a primary stroke center (PSC) destination policy in a major metropolitan city and to use geographic modeling in order to evaluate expected changes for a comprehensive stroke center policy. Suspected stroke emergency medical services encounters in Philadelphia, PA, were identified, and transport times before and after the initiation of a PSC destination policy in October 2011 were compared. Geographic modeling was used to estimate the impact of bypassing the closest hospital for the closest PSC or comprehensive stroke centers, which was common before the official policy and increased steadily over time. The researchers conclude that the time taken to route patients to PSCs or comprehensive stroke centers is low.

Identification of emergency department visits in Medicare administrative claims: approaches and implications.
The researchers sought to construct an operational definition for ED visitation using a comprehensive Medicare data set and to compare this definition to existing operational definitions used by researchers and policymakers. They concluded that current operational definitions of ED visitation using administrative claims produce different estimates of ED visitation based on the underlying assumptions applied to billing data and data set availability.
