Comments

This study examined differences in pharmaceutical utilization rates relative to financial risk arrangements of differing insurance plans. There are consistent differences in the utilization of expensive, psychotropic medications between individuals enrolled in Health Maintenance Organizations (HMOs), which are at financial risk for the provision of pharmaceuticals, and the MediPass program in which the state bears the risk of pharmacy expenses. In this study these analyses are expanded to include a broader range of pharmaceutical agents than were considered earlier and a broader range of diagnostic groups, including the addition of children. After defining diagnostically homogeneous groups the annual prevalence of nine mental health diagnoses, and penetration rate, the utilization rate and standard cost rates were calculated. Results indicated that prevalence of severe mental illnesses, access to, and utilization of more expensive pharmaceuticals was related to insurance plan. As with the pre-paid mental health plan evaluation, those persons who were enrolled in plans at risk for pharmacy costs (i.e., HMOs) had a lower rate of utilization of expensive drugs. Also, persons with more severe disorders were less prevalent in the HMO plans. Standard costs and utilization, for those who were given access, were lower in HMO financing plans relative to the MediPass plan for persons in the Adult Schizophrenia group who were taking atypical anti-psychotic (AAP) medication. This was not the case for other diagnostic groups and pharmaceutical categories. [Submitted to the Florida Agency for Health Care Administration as a deliverable under contract #M030]
