Background Recommendations on current clinical guidelines are informed by limited economic evidence. Aims A formal economic evaluation of three modalities of psychotherapy for patients with cluster B personality disorders. Method A probabilistic decision-analytic model to assess the cost-effectiveness of out-patient, day hospital and in-patient psychotherapy over 5 years in terms of cost per recovered patient-year and cost per quality-adjusted life-year (QALY). Analyses were conducted from both societal and payer perspectives. Results From the societal perspective, the most cost-effective choice switched from out-patient to day hospital psychotherapy at a threshold of (sic)12 274 per recovered patient-year; and from day hospital to in-patient psychotherapy at (sic)113 298. In terms of cost per QALY, the optimal strategy changed at (sic)56 325 and (sic)286 493 per QALY respectively. From the payer perspective, the switch points were at (sic)9895 and (sic)155 797 per recovered patient-year, and (sic)43 427 and (sic)561 188 per QALY. Conclusions Out-patient psychotherapy and day hospital psychotherapy are the optimal treatments for patients with cluster B personality disorders in terms of cost per recovered patient-year and cost per QALY.
