National Trends in Second-Generation Antipsychotic Augmentation for Nonpsychotic Depression

Results: From 1999 to 2010, 8.6% of adult depression visits included an SGA. SGA use rates increased from 4.6% in 1999-2000 to 12.5% in 2009-2010, with an adjusted odds ratio (AOR) for time trend of 2.78 (95% CI, 1.84-4.20). The increase in SGA augmentation was broad-based, with no significant differences in time trends between demographic and clinical subgroups. For the most recent survey years (2005-2010), SGA use rates were higher in visits to psychiatrists than to other physicians (AOR = 5.08; 95% CI, 2.96-8.73), visits covered by public than private insurance (AOR = 3.20; 95% CI, 2.25-4.54), visits with diagnosed major depressive disorder than other depressive disorders (AOR = 1.49; 95% CI, 1.08-2.06), and visits with diabetes, hyperlipidemia, or cardiovascular disease (AOR = 2.13; 95% CI, 1.12-4.03) and lower in visits by patients > 65 years than 18-44 years (AOR = 0.51; 95% CI, 0.32-0.82) and visits that included psychotherapy (AOR = 0.68; 95% CI, 0.47-0.96).
