The D2Hawkeye Rules Library is used to evaluate the quality of care provided, and to generate an individual’s Adjusted Risk Index (ARI). Members who are not compliant with quality measures are considered riskier, and receive higher ARIs.

The foundation of the Rules Library is evidence-based medicine and standards of care, as well as proprietary predictive measures. The Library reflects thousands of hours of research by the D2 Medical Group, and the contributions of specialists and statisticians from Harvard, MIT and Massachusetts General Hospital. The Library is continuously enhanced, based on feedback from our clients, the study of outliers and findings from our ongoing research.
