Patient-Reported Outcomes
SE
Both groups experienced increases in mean (SE) PAM-10 scores at 6 months (SUMMIT vs EUC within-group change, 3.5 [1.6] vs 2.3 [1.6]; difference, 1.2 [95% CI, −3.3 to 5.7]). Among the 3 CAHPS domains, SUMMIT participants reported increases in access (mean [SE], 5.7 [3.9] vs 4.0 [3.9]; difference, 1.7 [95% CI, −9.1 to 12.5]), communication (mean [SE], 5.2 [3.5] vs −3.7 [3.5]; difference, 9.0 [95% CI, −0.7 to 18.7]), and coordination (mean [SE], 9.8 [4.4] vs 0.5 [4.4]; difference, 9.2 [95% CI, −3.1 to 21.6]) relative to EUC participants, although these differences between groups were not significant. The SUMMIT participants also experienced nonsignificant increases in mean (SE) SF-12 physical health composite scores (2.5 [1.1] vs 0.7 [1.1]; difference, 1.8 [95% CI, −1.3 to 4.9]) and SF-12 mental health composite scores (2.2 [1.7] vs 0.1 [1.7]; difference, 2.2 [95% CI, −2.5 to 6.8]) relative to EUC participants. The SUMMIT participants compared with EUC participants had significantly greater increases in the SF-12 social functioning subdomain (mean [SE], 4.7 [2.0] vs −1.1 [2.0]; difference, 5.8 [95% CI, 0.3 to 11.2]) and in self-rated health (mean [SE], 0.7 [0.3] vs −0.2 [0.3]; difference, 1.0 [95% CI, 0.1 to 1.8]) (
