Ethnic disparities in treatment were also the focus of a study in British Columbia, in which Joseph H. Puyat, M.Sc., M.A., and colleagues examined antipsychotic prescription refill data in a large population with significant Asian representation. They found evidence of persistent disparities among Chinese individuals (page 1026). Two other studies in this issue examined prescription data. In a U.S. study, Karen L. Rascati, R.Ph., Ph.D., and colleagues examined Medicaid claims data for 2,446 patients with bipolar disorder for whom five different second-generation antipsychotics were prescribed. They found no significant differences in adherence between medication groups. However, fewer than half of the patients received a clinically recommended dosage (page 1032). In Israel, Liat Ayalon, Ph.D., and colleagues examined data from a national sample of 30,000 adult primary care patients, 19% of whom received antidepressant or antianxiety medications. They found disparities between population groups despite universal health coverage (page 1041).
