Physician service patterns and illness rates

the long version

This study was undertaken by Group Health Insurance (GHI) to demonstrate the wealth of medically relevant data which can be produced as a by-product of medical insurance administration. The flow of original source data presented in "Physician Service Patterns" contains much of substantive value; equally important is the demonstration of what can be done. It is our belief that every type of data examined for this exploratory project bears directly or indirectly on the work of medical care analysts and planners, epidemiologists, sociologists, physicians, hospital administrators, insurers, welfare fund trustees and research fund allocators.
