Summary of cost-effectiveness results comparing BA in addition to usual care versus usual care alone
| Treatment option | Total healthcare costs (95% CrI) | Incremental costs, over usual care (95% CrI) | DALYs averted (95% CrI) | Incremental DALYs averted, over usual care (95% CrI) | Incremental net monetary benefit, over usual care (95% CrI) | ICER |
| Usual care | US$10 839 (US$7205 to US$17 088) | – | −3.5 (7.96 to −9.58) | – | – | |
| BA (excluding BA treatment costs) | US$10 742 (US$7187 to US$16 803) | −US$97 (−US$517 to US$142) | −2.52 (9.07 to −8.70) | 0.98 (1.86 to 0.45) | US$276.63 (US$23.92 to US$717.12) | Dominates usual care |
| BA (including BA treatment costs of $15) | US$10 792 (US$7237 to US$16 854) | −US$47 (−US$467 to US$192) | −2.52 (9.07 to −8.70) | 0.98 (1.86 to 0.45) | US$226.48 (−US$26.22 to US$666.97) | Dominates usual care |
BA, behavioural activation; CrI, credible interval; DALYs, disability-adjusted life-year; ICER, incremental cost-effectiveness ratio.
