The Health Enhancement Research Organization (HERO) and Population Health Alliance (PHA) are pleased to present (herein referred to as “Guide”),a core set of metrics for the evaluation of employee health management programs. After two years and countless hours of research and discussions by more than 60 members of both organizations and many outside experts, HERO and PHA are responding to employers who seek a greater level of clarity regarding the value of their wellness efforts. Thus, we recommend an initial set of measures to assess the impact of the health management programs offered to employees. The results are better informed business decisions and boardroom discussions.
