A total of 213 participants (65.5%) were male at birth, 28 (8.6%) were American Indian or Alaska Native, 21 (6.5%) were Black, 156 (48.0%) were Hispanic, and 125 (38.5%) were White. More than half, 175 (53.8%), were unhoused in the past year, and 163 (50.2%) were unemployed. START participants were more likely than usual care participants to initiate MOUD during hospitalization (94\/164 [57.3%] vs 43\/161 [26.7%], respectively; adjusted risk ratio [aRR], 2.10 [97.5% CI, 1.51-2.91]) and to link to OUD care after discharge (90\/125 [72.0%] vs 50\/104 [48.1%], respectively; aRR, 1.49 [97.5% CI, 1.15-1.93]).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions and
