Public health surveillance approaches in Oregon's Medicaid population.

The development of methods for public health surveillance in Medicaid populations is an important goal for public health practice. In Oregon, we developed approaches to case finding using claims and self-reported data obtained from the Medicaid beneficiary population. Disease rosters, derived from claims data, form the basis for analyses pertaining to particular health conditions.
