ARREST
In total, 782 patients were included in analysis (mean [SD] age, 56.6 [12.7] years; 395 [50.5%] female and 387 [49.5%] male; 231 [29.5%] Hispanic, 427 [54.6%] non-Hispanic Black, and 124 [15.9%] non-Hispanic White). Our gradient-boosting machine model estimating intervention exposure performed well with an area under the receiver operating characteristic curve (SD) of 0.81 (0.02). Factors with the greatest associations were patient age, prior number of hospitalizations, length of index admission, housing status at enrollment, and arrest history (eAppendix 3 in
