Among individuals with major depressive disorder (MDD), increased severity status is associated with incremental economic burden in patients with treatment-resistant depression (TRD), a new study found. Adult patients with TRD were identified who were stratified into mild, moderate, and severe cohorts based on the information in the last observed MDD ICD-9-CM code. Healthcare resource utilization (HRU) and costs of moderate to severe cohorts were compared to those of the mild cohort during 2-year follow-up after the first antidepressant claim. Among the findings:
- Among 6,411 patients with TRD, 455 (7.1%) were identified as mild, 2,153 (33.6%) as moderate, and 1,455 (22.7%) as severe.
- Increased severity status was associated with incremental burden in patients with TRD.
- Inpatient admissions and outpatient visits were key drivers of incremental costs.
