About Us


Created during the 2011 Legislative session, the Health Evidence Review Commission (HERC), combined two previously existing commissions, the Health Services Commission and Health Resources Commission.  HERC continues two decades of work, as both of the original commissions began their work in the early 1990s at the start of the Oregon Health Plan.

The Commission consists of 13 Governor-appointed and senate-confirmed volunteer members including six physicians (one of whom must be a doctor of osteopathy), a dentist, a public health nurse, a behavioral health representative, a provider of complementary and alternative medicine, a retail pharmacist and two consumer representatives.

A Brief History of Health Services Prioritization in Oregon


Aware of the need for accountable and effective funding of health care, Oregon established a set of policy objectives to guide the development of a methodology for setting health care priorities. In 1989, the Oregon Legislature created the Health Services Commission and directed it to develop a prioritized list of health services ranked in order of importance to the entire population to be covered. The Commission first tested a formulaic approach using a cost/utility analysis, but the results were unsatisfactory. Subsequent successful approaches rank- order general categories of health services (e.g., Maternity and newborn care; Comfort care) based on relative importance as gauged by public input and on Commissioner judgment. Within these general categories, individual condition/treatment pairs are prioritized according to impact on health, effectiveness and (as a tie-breaker) cost. The resulting prioritized list is used by the Legislature to allocate funding for Medicaid and SCHIP, but the Legislature cannot change the priorities set by the independent Commission. The benefits based on the prioritized list are administered primarily through managed care plans, and approximately 1.5 million Oregonians have gained health coverage due to the expanded access made possible by explicitly prioritizing health services.
