1. A computer implemented method for generating a chronic condition risk index for an individual using said individual's pharmacy claims by a computer system, said method comprising the steps of: (1) retrieving by the computer system said pharmacy claims from a pharmacy claims database, and processing by the computer system said pharmacy claims to identify any chronic conditions possessed by said individual; (2) processing by the computer system said pharmacy claims to identify any compliance medications prescribed to said individual; (3) generating a chronic condition score by summing regression coefficients for each chronic condition possessed by said individual; (4) generating a compliance medication score by summing products of regression coefficients for each compliance medication prescribed to said individual with associated medication supply weights, or compliance; (5) generating a modified chronic condition score by multiplying said chronic condition score by an overall chronic condition regression coefficient; (6) further modifying said modified chronic condition score by subtracting a no-claims weight from said chronic condition score, if said individual has no pharmacy claims; and (7) generating, by the computer system, said chronic condition risk index by summing said modified chronic condition score and said compliance medication score.
