Abstract
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. Participants were adults ≥ 18 years with MS presenting to any of the 4 MS-CQI centers. DMT utilization was categorized into oral, infusion, and injection types. Multinomial logistic regression was used to investigate associations between centers and DMT utilization. RESULTS: Overall, 2,029 patients were included in the analysis. Of those patients, 75.1% were female, mean age was 50 years, and 87.4% had relapsing-remitting MS. Overall, 32.7% were on an oral DMT, 23.5% on an infusion DMT, and 43.9% on an injection DMT. Overall, statistically significant differences (p < 0.01) were observed across centers for proportions of patients who received oral, infusion, and no DMTs. There were also overall significant differences (p < 0.01) across MS types for proportions of encounters who received oral, infusion, injection, no DMTs, and mean age varied significantly across centers. CONCLUSION: System-level effects on MS treatment and outcomes have not been previously studied and our findings contribute initial evidence concerning system-level variation in DMT utilization. Results suggest system-level variation in DMT utilization (ie, after adjusting for individual level factors, MS center or location of care a person with MS engages in care influences DMT treatment choices), resulting in a lack of standardization in DMT management. Continued research and improvement efforts targeting system-level performance could improve outcomes for people with MS.
