Prescription medication
By 12 months, participants in the case management group were taking 0.8 (0.05-1.1) fewer total medications per day than those in the usual care group (P = 0.03) (Fig. 2B). More individuals in the case management group decreased total medications compared with those in the usual care group (45 vs. 28%, respectively), and fewer individuals in the case management group increased medications compared with those in the usual care group (19 vs. 35%) (x^sup 2^ = 6.6, 2 df; P = 0.03) at 6 months. Although the magnitude of the differences remained similar (decrease: 57 vs. 39%; increase: 17 vs. 32%), these differences were no longer significant by 12 months (P = 0.13).
