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.
