IS/IT the prescription to enable medical group practices attain their goals.

The US spends significantly more money as a percentage of GDP on health care than any other OECD country and more importantly, this amount is anticipated to increase exponentially. In this high cost environment, two important trends have occurred: (1) the movement to managed care, and (2) large investments in Information Systems/Information Technology (IS/IT). Managed care has emerged as an attempt to provide good quality yet cost effective health care treatment. Its implications are not well discussed in the literature while, its impact on different types of medical group practices is even less well understood. The repercussions of the large investments in IS/IT on the health care sector in general and on the medical group practice in particular, although clearly of importance, are also largely ignored by the literature. This study attempts to address this significant void in the literature. By analyzing three different types of group practices; an Independent Practice Association (IPA), a Faculty Practice and a Multi Specialty Group Practice in a managed care environment during their implementation of practice management/billing systems, we are able to draw some conclusions regarding the impacts of these two central trends on health care in general as well as on the medical group practice in particular.
