Health care policy and health information environment variables relevant to survivorship care planning (e.g., electronic and personal health records (EHRs and PHRs)) are dynamic and change rapidly. The GEM-Care Planning Initiative (GEM-CP), a project initiated by the National Cancer Institute's Health Communication and Informatics Research Branch (HCIRB) and Office of Cancer Survivorship, is intended to build consensus in the survivorship community around high-priority process and outcome measures for use in studies of survivorship care planning. Increased use of shared measures will enable comparability across studies and facilitate expeditious identification of strategies to implement optimal care planning - or barriers to that planning - for cancer survivors.
