When Medicare patients move, healthcare spending changes


When healthcare spending varies widely from one geographical region to another, including for pricey procedures like imaging exams, which variable is more to blame—provider choices or patient preferences?

MIT economist Heidi Williams, PhD, a co-author of the study, tells MIT News that some geographic spending variations may be explained by provider populations being more skilled at certain procedures—and thus more inclined to order them—in some areas than in others.

The researchers further found that, when Medicare enrollees relocate, most of their healthcare spending happens within the first year after the move.

About Me

As a Dermatologist and Informatician my research mainly involves application of bioinformatics techniques and tools in dermatological conditions. However my research interests are varied and I have publications in areas ranging from artificial intelligence, sequence analysis, systems biology, ontology development, microarray analysis, immunology, computational biology and clinical dermatology. I am also interested in eHealth, Health Informatics and Health Policy.
