The goal of disease management (:DM) is to improve outcomes while opti
mizing the overall use of health care resources. However, few publishe
d studies have formally evaluated how well a DM program meets that goa
l. This paper provides a systems model for evaluating DM programs from
the perspective of the health care plan, The proposed evaluation mode
l has seven steps: adopting a systems perspective; establishing a fram
ework for evaluation; identifying key structures, processes, and outco
mes; developing specific performance measures; collecting, processing,
modeling, and analyzing performance measurement data; making comparis
ons to criteria, standards, and goals; and, finally, conducting a form
al evaluation of how well the DM program has met its objectives.
