Objective:
Post-hoc economic evaluation of a bio-psycho-social intervention in post-war Kosovo from a societal perspective.
Design:
Cost-effectiveness analysis, cost-utility analysis, and partial cost-benefit analysis using data from a randomized controlled trial.
Patients:
Thirty-four torture/war victims with comorbid conditions enrolled in 2012-2013.
Methods:
Participants were randomly assigned to an "intervention" and a "waiting-list" group. Changes in mental, emotional and physical health and functional impairment were assessed before and after treatment, along with increase in labour income as a proxy for productivity gain. The cost of an extra unit of effectiveness and an additional quality-adjusted life year were calculated.
Results:
The total cost per participant was €1,322 including, or €1,019 excluding, research costs. Wide variations in costs of changes in mental, emotional and physical effectiveness were demonstrated. Multidisciplinary intervention resulted in functional improvement at a cost of €10,508 per quality-adjusted life year gained. With a mean monthly income increase to €133 (18%) after intervention, the intervention cost per participant would be equal to the total increase in monthly income after 4-5 years, assuming the increased level is maintained.
Conclusion:
Socio-economic benefit associated with quality-adjusted life year gain is shown, although the cost of an additional quality-adjusted life year is above the World Health Organization cost-effectiveness threshold.
