CMP was successful in reducing death for all patients. For complex patients with diabetes mellitus in the intervention group, death and hospital usage were lower. Per clinic, hypothesized savings from decreased hospitalizations was $17,384 to $70,349.

The SF-12 survey provided additional predictive ability for future hospitalizations and mortality. Such predictive ability might facilitate preemptive interventions that would change the course of disease in this segment of the population. However, nonresponder bias may limit the utility of mailed SF-12 surveys in certain populations.
