ISPOR Task Forces are created to advance the field of health care outcomes research and the use of this research in health care decisions. A Task Force is approved by the ISPOR Board of Directors to achieve a defined goal such as the development of a "good research practice" document or similar document. A Task Force is composed of a Leadership Group, who develop the document and a Reviewer Group, who provide feedback and comments to the document. The Leadership Group is selected by the Task Force Chair(s). The Reviewer Group is composed of any ISPOR member who is interested in the goal of the Task Force. When the goal of a Task Force is achieved, the Task Force is dissolved.
