Abstract
This brief commentary extends earlier work on the value of adherence to derive medical cost offset estimates from prescription drug utilization. Among seniors with chronic vascular disease, 1% increases in condition-specific medication use were associated with significant (P less than 0.001) reductions in gross nonpharmacy medical costs in the amounts of 0.63% for dyslipidemia, 0.77% for congestive heart failure, 0.83% for diabetes, and 1.17% for hypertension.
