3M has developed a composite measure, a 3M™ Value Index Score, which provides a standard metric to assess accountable value in health care. This index score is a composite measure based on six critical primary care domains derived from 16 measures of key processes and outcomes that effect value in health care. According to 3M, this Value Index Score can increase the understanding of provider and system performance thereby accelerating and prioritizing the areas where improvement is needed. This measure...
