Treatment-resistant depression (TRD) exacts substantial toll on quality of life and heavy price in treatment costs.

“Treatment-resistant depression exacts a heavy price in treatment costs and lost productivity, reaching into the tens of billions of dollars, but its effects on the lives of patients are just as devastating. In this literature review, the authors summarize 62 studies documenting the disease’s toll on quality of life, personal financial resources, and general health. The average patient in the included studies had experienced nearly four earlier episodes of depression, had not responded to 4.7 drug trials, and continued to meet or nearly meet criteria for severe depression.”

TRD associated with higher per-patient medical costs.

“The classification of TRD had a clinically meaningful and statistically significant association with increased medical expenditures. Holding all else equal, the classification of TRD was associated with a 29.3% higher costs (P < 0.001) in medical expenditures compared with patients not meeting the study definition of TRD."

Using atypical antipsychotics may improve clinical response in MDD patients who are refractory to antidepressant therapy.

“With antidepressant therapy alone, the estimated clinical response rate at 6 weeks was 30%.”

TRD imposes substantial cost on employers.

“Compared with major depressive disorder (MDD) controls, TRD-likely employees had significantly higher rates of mental-health disorders, chronic pain, fibromyalgia, and higher Charlson Comorbidity Index. Average direct 2-year costs were significantly higher for TRD-likely employees ($22,784) compared with MDD controls ($11,733), p < 0.0001. Average indirect costs were also higher among TRD-likely employees ($12,765) compared with MDD controls ($6885), p < 0.0001."

Individuals with TRD use more healthcare services.

“The average annual cost of employees considered TRD-likely was dollars US 14490 per employee, while the cost for depressed but TRD-unlikely employees was dollars US 6665 per employee, and dollars US 4043 for the employee from the random sample. TRD beneficiaries used more than twice as many medical services compared with TRD-unlikely patients, and incurred significantly greater work loss costs.”
