Cost-effectiveness and cost-utility of selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and tricyclic antidepressants in depression with comorbid cardiovascular disease

Objective: There is a lack of clarity in the literature regarding the cost-effectiveness and cost-utility of antidepressants for treating real-world patients. The impact of comorbid cardiovascular disease (CVD) on the economic evaluations of antidepressants remains to be determined. Method: Adult patients prescribed with antidepressants for depression were identified from the National Health Insurance Research Database in Taiwan. A cost-effectiveness and cost-utility analysis was conducted comparing selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), and tricyclic antidepressants (TCAs), and by the presence of comorbid CVD. Results: In terms of treatment success rates, SSRIs were the most cost-effective option compared to TCAs and SNRIs as revealed in the incremental cost-effectiveness ratios. The cost-effectiveness acceptability curves further showed differential findings in the cost-utility results by the presence of comorbid CVD. Conclusion: To improve treatment success rates and quality-adjusted life years, SSRIs can be considered the most cost-effective option. Future research is needed to further clarify the impacts of physical comorbidities and other associated factors on the cost-effectiveness and cost-utility of pharmacological treatments in patients with depression.
