Measure
Ocrelizumab, OCREVUS
Patients eligible for this study will be receiving OCREVUS (also known as Ocrelizumab) as part of their routine care for multiple sclerosis (MS) treatment, and undergo the standard monitoring tests and procedures for multiple sclerosis (MS) patients receiving treatment. In addition, they will complete the Expanded Disability Status Scale (EDSS) scale on 6 occasions over a 12-month period, and the Multiple Sclerosis Impact Scale (MSIS-29) on three occasions during the 12 month period for research.

SECONDARY outcome

Timeframe: 12 months

Average change in EDSS score. The Expanded Disability Status Scale (EDSS) is an assessment used by neurologist to assess changes in the level of disability over time in patients with MS. The EDSS scale ranges from 0 to 10 in 0.5 unit increments that represent higher levels of disability. Scores are also based on measures of impairment in the 8 functional systems. Higher scores indicate greater impact of MS on QoL.

SECONDARY outcome

Timeframe: 6 and 12 months

Average change in MSIS-29: Multiple Sclerosis Impact Scale (MSIS) is a patient reported outcome (PRO) measure, consisting of two subscales- physical impact of MS (20 items) and psychological impact (9 items). It asks subject to rate the impact MS has their daily life in the past 2 weeks (1=low impact to 4=large impact). Scores from individual items are summed to a total score. Physical impact score ranges from 20-80 and psychological impact scores ranges from 9-36. Higher scores indicate greater impact of MS on QoL.
