Insights
Cognitive Behavioural Therapy (CBT) is a cost-effective treatment for major depressive disorder (MDD) in adults for short-term care and relapse prevention. This systematic review analyzed cost-utility analyses of CBT for MDD.
Area of Science:
- Health Economics
- Psychiatry
- Evidence-Based Medicine
Background:
- Major Depressive Disorder (MDD) presents a significant global health burden.
- Cognitive Behavioural Therapy (CBT) is a key intervention for depression.
- Cost-Utility Analysis (CUA) informs resource allocation in health policy.
Purpose of the Study:
- To systematically review CUAs of CBT for MDD treatment.
- To assess the economic value of CBT interventions for depression.
Main Methods:
- Systematic literature search across major databases (Medline, Embase, PsycINFO, NHS EED).
- Standardized cost data adjustment (year 2011, USD PPP).
- Quality assessment of included CUAs.
Main Results:
- Twenty-two studies were included in the review.
- Individual, group, and maintenance CBT generally showed acceptable cost-utility ratios (<50,000 USD PPP/QALY).
- CUA results for pediatric and computerized CBT were inconsistent.
Conclusions:
- Consistent evidence supports individualized CBT as cost-effective for short-term MDD treatment and relapse prevention in adults.
- Findings are from a third-party payer perspective.
- Short time horizons (<5 years) were common across studies.
Background:
Major depressive disorder (MDD) causes a massive disease burden worldwide. Cognitive behavioural therapy (CBT) is an important treatment approach for depression. Cost-utility analysis (CUA) is a method to support decisions on efficient allocation of resources in health policy. The objective of our study was to systematically review CUA of CBT in the treatment of patients suffering from MDD.
Methods:
We conducted a systematic literature search in Medline, Embase, PsycINFO and National Health Service Economic Evaluation Database (NHS EED) to identify CUA of CBT for MDD. Cost data were inflated to the year 2011 and converted into USD using purchasing power parities (USD PPP) to ensure comparability of the data. Quality assessment of CUA was performed.
Results:
Twenty-two studies were included in this systematic review. No study employed a time horizon of more than 5 years. In most studies, individual and group CBT as well as CBT for maintenance showed acceptable incremental cost-utility ratios (<50,000 USD PPP/quality-adjusted life year). The CUA results of CBT for children and adolescents and of computerized CBT were inconsistent.
Discussion:
We found consistent evidence that individualized CBT is cost-effective from the perspective of a third-party payer for short-term treatment and for relapse prevention of MDD in the adult population.
