Abstract: Background: A brief psychodynamic interpersonal therapy (PIT) in patients with multisomatoform disorder has been recently shown to improve health-related quality of life. Aims: To assess cost-effectiveness of PIT compared to enhanced medical care in patients with multisomatoform disorder. Method: An economic evaluation alongside a randomised controlled trial (International Standard Randomised Controlled Trial Number ISRCTN23215121) conducted in 6 German academic outpatient centres was performed. Incremental cost-effectiveness ratio (ICER) was calculated from the statutory health insurance perspective on the basis of quality adjusted life years (QALYs) gained at 12 months. Uncertainty surrounding the cost-effectiveness of PIT was presented by means of a cost-effectiveness acceptability curve. Results: Based on the complete-case analysis ICER was 41840 Euro per QALY. The results did not change greatly with the use of multiple imputation (ICER = 44222) and last observation carried forward (LOCF) approach to missing data (ICER = 46663). The probability of PIT being cost-effective exceeded 50% for thresholds of willingness to pay over 35 thousand Euros per QALY. Conclusions: Cost-effectiveness of PIT is highly uncertain for thresholds of willingness to pay under 35 thousand Euros per QALY.
