dc.description.abstractAdherence to combination antiretroviral therapy is important for achieving optimal HIV-related outcomes. Epidemiologic data indicate that persons with mental disorders are disproportionately affected by HIV/AIDS, which is concerning since having a mental disorder has been associated with poor adherence to medications for treatment of chronic disease states. The purpose of this study was to examine the relationship between the presence of mental disorders and adherence to combination antiretroviral therapy. Additionally, this study examined the relationship between adherence to psychotropic medications and adherence to antiretroviral therapy. Study data were collected from the Texas Medicaid Vendor Drug Program database and Texas Medicaid enrollment files. Adherence to and persistence with antiretroviral therapy, as well as adherence to psychotropic medications when applicable, were evaluated over a 12-month period in 1,321 patients starting a new combination antiretroviral regimen. The presence of a mental disorder was defined based on prescription claims for psychotropic medications. Proportion of days covered was used to calculate adherence, while persistence was defined as the number of days persistent with all antiretrovirals in the index regimen. Logistic regression was used to evaluate the relationship between psychotropic medication use and adherence to antiretroviral therapy (90% cut-off), as well as the relationship between adherence to psychotropic medications (80% cut-off) and adherence to antiretroviral therapy. The relationship between antiretroviral persistence and psychotropic medication use was evaluated using multiple linear regression. Factorial ANOVA was used to evaluate the interactions between race/ethnicity, gender, and psychotropic medication use in their effects on adherence to and persistence with antiretroviral therapy. No significant relationship was found between the presence of a mental disorder and adherence to or persistence with combination antiretroviral therapy in this study. However, the limitations of using psychotropic medication use as a proxy for mental disorders may have affected the results. Adherence to psychotropic medications overall (n = 501; OR = 3.37, 95% CI: 1.86 – 6.10; p < 0.001) and specifically to antidepressants (n = 443; OR = 4.23, 95% CI: 2.31 – 7.75; p < 0.001) was significantly associated with adherence to antiretroviral therapy, indicating a possible relationship between effective treatment for mental disorders and combination antiretroviral therapy adherence. While additional research is needed to clarify this relationship, these data support the need for an integrated approach to treatment of mental disorders and HIV/AIDS.en
