System-Level Variation in Multiple Sclerosis Disease-Modifying Therapy Utilization: Findings From the Multiple Sclerosis Continuous Quality Improvement Research Collaborative.

Background: The Multiple Sclerosis Continuous Quality Improvement (MS-CQI) Collaborative is the first multicenter improvement research collaborative for multiple sclerosis (MS). The main objective of this study is to describe baseline system-level variation in disease-modifying therapy (DMT) utilization across 4 MS centers participating in MS-CQI.

Methods: Electronic health record data from the first year of the 3-year MS-CQI study were analyzed.
