Objectives. To assess health state utility values (HSUVs) in caregivers of older patients with chronic diseases receiving or not social worker support.Methods. This multicentric open-label randomized study assigned caregivers to receive either an informational booklet alone or accompanied by social worker support. Caregivers completed EQ-5D-3L each semester for 24 months. We reported caregiver HSUVs at baseline, 6, 12, 18 and 24 months using EQ-5D-3L utility index scores and exploring their time-to-deterioration (TTD).Results. Among 179 included caregivers, the percentage reporting some or extreme problems on five EQ-5D-3L dimensions remained almost stable over time with a median EQ-5D-3L utility index score of 0.89 [0.80-1.00] at baseline (n=177), 0.80 [0.80-0.89] at M6 (n=125) and 0.80 [0.73-0.91] at M24 (n=81). Sixty-two percent of respondents (n=109) experienced a deterioration in EQ-5D-3L utility index score with a median TTD of 9.1 months [95%CI 6.2-14.9] in the CG and 9.5 months [6.3-14.4] in the SIG (HR = 1.06 [0.73-1.54], p-value=0.76. Conclusion. Our study provides a HSUVs catalog across different caregiver profiles and at various follow-up timepoints which can inform future economic evaluations.
