Founded in 2012, the International Consortium for Health Outcomes Measurement (ICHOM) has made significant impact on defining outcomes measurement sets for major diseases, with the goals of informed decision making, quality improvement, and reduced costs. ISPOR shares these goals and has also had major impact on outcomes research methods, particularly in the context of value assessment. This session will describe the complementary activities of both organizations and explore how together we can further the use of scientifically rigorous outcome measures in health care decision making.
