“…7,16,18,19 One such U.S. study of employees with MS and at least 1 DMT claim versus untreated employees with MS found that the risk-adjusted total annual medical costs ($4,393 vs. $6,187; P < 0.001) and indirect costs ($2,252 vs. $3,053; P < 0.001) were significantly lower for employees with at least 1 DMT claim. 43 With regard to differences between DMTs in MS-associated absenteeism, Brook et al (2009) found that patients receiving IM IFNβ-1a had lower sick-leave costs ($969 vs. $523, respectively; P = 0.047) and fewer sick-leave days (2.98 vs. 7.18 days, respectively; P = 0.01) versus those receiving GA. 81 Similarly, Rajagopalan et al (2011) reported that patients treated with IM IFNβ-1a demonstrated a significant improvement in the number of missed work days, with a decrease of 1.3 days (from 5.6 to 4.3 days) versus an increase of 2 days (from 2.3 to 4.3 days), in GA-treated patients (P < 0.05). 38 Only patients receiving IM IFNβ-1a showed a reduction in sick-leave absence days with therapy, while sick leave increased with SC IFNβ-1a, IFNβ-1b, and GA.…”
