Evidence‐Based Medicine and State Health Care Coverage: The Washington Health Technology Assessment Program

Objective

To evaluate the Washington State Health Technology Assessment Program (WHTAP ).

Study Setting

Washington State Health Technology Assessment Program proceedings in Seattle, Washington.

Data Collection and Study Design

We assessed the program through observation of its proceedings over a 5‐year period, 2009–2014. We conducted detailed analyses of the documents it produced and reviewed relevant literature.

Principal Findings

Washington State Health Technology Assessment Program is unique compared to other state and federal programs. It has successfully applied evidence‐based medicine to health care decision making, limited by the strength of available data. It claims cost savings, but they are not substantiated.

Conclusions

Washington State Health Technology Assessment Program is a useful model for other states considering implementation of technology assessment programs. We provide key lessons for improving WHTAP 's process.
