The EHR is being developed to provide higher quality coordinated care at reasonable cost.
Health statistics already integrate data analytically and sometimes link information probabilistically—that is at a summary level but not for individuals.
As new information technology applications change how health information is compiled for individuals, providers and payers, health statistics will help make sense of the resulting data.
At the same time, health statistics methods and sources will change.
The electronic health record will enhance existing statistical work, but it will likely offer similar benefits and face the similar problems that are characteristic of existing sources based on health care delivery.
