The effect of antidepressant treatment on HIV and depression outcomes: results from a randomized trial.
BACKGROUND: Depression is a major barrier to HIV treatment outcomes. OBJECTIVE: To test whether antidepressant management decision support integrated into HIV care improves antiretroviral adherence and depression morbidity. DESIGN: Pseudo-cluster randomized trial. SETTING: Four US infectious diseases clinics. PARTICIPANTS: HIV-infected adults with major depressive disorder. INTERVENTION: Measurement-based care (MBC) - depression care managers used systematic metrics to give HIV primary-care clinicians standardized antidepressant treatment recommendations. MEASUREMENTS: Primary - antiretroviral medication adherence (monthly unannounced telephone-based pill counts for 12 months). Primary time-point - 6 months. Secondary - depressive severity, depression remission, depression-free days, measured quarterly for 12 months. RESULTS: From 2010 to 2013, 149 participants were randomized to intervention and 155 to usual care. Participants were mostly men, Black, non-Hispanic, unemployed, and virally suppressed with high baseline self-reported antiretroviral adherence and depressive severity. Over follow-up, no differences between arms in antiretroviral adherence or other HIV outcomes were apparent. At 6 months, depressive severity was lower among intervention participants than usual care [mean difference -3.7, 95% confidence interval (CI) -5.6, -1.7], probability of depression remission was higher [risk difference 13%, 95% CI 1%, 25%), and suicidal ideation was lower (risk difference -18%, 95% CI -30%, -6%). By 12 months, the arms had comparable mental health outcomes. Intervention arm participants experienced an average of 29 (95% CI: 1-57) more depression-free days over 12 months. CONCLUSION: In the largest trial of its kind among HIV-infected adults, MBC did not improve HIV outcomes, possibly because of high baseline adherence, but achieved clinically significant depression improvements and increased depression-free days. MBC may be an effective, resource-efficient approach to reducing depression morbidity among HIV patients.
