Abstract Aims We aimed to assess the cost-effectiveness of psychiatric advance directives (PAD) facilitated by peer workers (PW-PAD) in the management of patients with mental disorders in France.

We assessed differences in societal costs in euros (€) and quality-adjusted life-years (QALYs) over a year-long follow-up to estimate the incremental cost-effectiveness ratio of the PW-PAD strategy. We conducted multiple sensitivity analyses to assess the robustness of our results. Results Among the 394 randomized participants, 196 were assigned to the PW-PAD group and 198 to the control group. Psychiatric inpatient costs were lower in the PW-PAD group than the control group (relative risk, −0.22; 95% confidence interval, [−0.33 to −0.11]; P
