Direct and Indirect Cost Burden and Change of Employment Status in Treatment-Resistant Depression: A Matched-Cohort Study Using a US Commercial Claims Database.
JOURNAL OF CLINICAL PSYCHIATRY(2018)
摘要
Background: Treatment-resistant depression (TRD) poses a substantial burden to health care payers including employers, costing an estimated $29 billion-$48 billion yearly in the United States. Furthermore, variation of burden across increasing levels of resistance and the potential impact of TRD on employment status remain largely unexplored. Objective: To evaluate health care resource utilization (HRU) and costs, work loss, indirect costs, and employment status change in TRD. Methods: A claims-based algorithm identified adults with TRD from a US claims database of privately insured employees and dependents (January 2010-March 2015). TRD patients were matched 1:1 on demographics to patients with major depressive disorder (MDD) (non-TRD MDD) and without MDD (non-MDD), who were identified using ICD-9-CM codes. Costs, HRU, and employment status change were compared over 2 years following the first antidepressant (randomly imputed date for non-MDD), adjusting for baseline comorbidity index and costs. Results: TRD patients (N = 6,411) had more HRU than either matched control cohort, translating into higher per patient per year (PPPY) health care costs: $6,709 and $9,917 more than nonTRD MDD and non-MDD patients, respectively (P < .001 for both). TRD patients with work loss data (N = 1,908) had 35.8 work loss days PPPY (1.7 and 6.2 times the work loss rate in non-TRD MDD and non-MDD patients, respectively). Work loss-related costs in TRD patients were $1,811 higher than non-TRD MDD and $3,460 higher than in non-MDD patients (P < .001). TRD patients had 1.3-1.4 times the rate of employment status change versus control cohorts (all P < .05). Conclusions: TRD, even compared to MDD, poses a significant direct and indirect cost burden to US employers and may be associated with higher rates of employment status change.
