Their study covered 13,992 Medicaid beneficiaries, of whom 25 percent were black, 37 percent Latino, and 38 percent white. Adjustment for need confirmed a disparity between Latinos and whites (odds ratio=.58). However, including geographic location in the model eliminated the Latino-white disparity but confirmed the role of geographic variation in adoption of the long-acting injectable version of risperidone, wrote the RAND Corporation’s Marcela Horvitz-Lennon, M.D., M.P.H., and colleagues in the just-released December Psychiatric Services.
The authors suggest that cultural or organizational factors may play a role in these geographic differences. Culturally, the views of opinion leaders among physicians or attitudes toward pharmaceutical promotion of a new medication version might have influenced adoption of this medication. Alternatively, a key organizational factor might have been geographic variations in the availability of nurses to administer these injections.
