SE, reductions in mean (
The SUMMIT and EUC groups experienced similar declines in mean (SE) 6-month hospitalization rates (SUMMIT vs EUC within-group change, −0.6 [0.5] vs −0.9 [0.5] hospitalizations per person; difference, 0.3 [95% CI, −1.0 to 1.5]). Both groups also had similar reductions in mean (SE) 6-month ED visit rates (−2.0 [1.0] vs −0.9 [1.0]; difference, −1.1 [95% CI, −3.7 to 1.6]). The SUMMIT participants experienced significantly greater increases in mean (SE) primary care visits (4.2 [1.6] vs −2.0 [1.6] visits per person; difference, 6.1 [95% CI, 1.8 to 10.4]) and behavioral health visits (4.7 [1.1] vs −1.1 [1.1] visits per person; difference, 5.8 [95% CI, 2.8 to 8.8]) relative to EUC participants (
