We describe treatment patterns, healthcare utilization, and cost among MS patients newly initiating DMTs (index).Patients and Methods: DMT-naïve adults with 12 months’ continuous enrollment pre- and post-index and ≥ 2 MS claims (2009‒2018) were identified from the Optum Clinformatics Data Mart database. Treatment adherence and persistence were measured as time on index DMT. Relapses were identified using a validated claims-based algorithm. All-cause and MS-related healthcare expenditures and utilization were captured pre- and post-index. Outcomes were stratified by route of administration. Multivariate analyses assessed differences in outcomes and costs.Results: The analysis included 5906 MS patients (mean age, 46.6 years). The majority initiated injectable (63.5%) followed by oral (28.8%) and infusion (7.7%) DMTs. Post-index, 45.3% of patients were nonadherent and 39.4% were nonpersistent. Relapse rates decreased from pre- to post-index (oral: 24.3%‒16.1%; injectable: 25.0%‒17.1%; infusion: 29.3%‒15.5%). Post-index mean (SD) all-cause total costs were lowest with oral ($70,970 [$36,681]) vs injectable ($82,521 [$58,569]) and infusion ($80,871 [$49,627]) DMTs. MS-related total costs were lowest with oral ($65,149 [$65,133]) vs injectable ($76,197 [$60,204]) and infusion ($72,703 [$47,287]) DMTs. Multivariate analysis showed no differences between oral and injectable DMTs in adherence, persistence, or relapse rate; however, oral DMTs had significantly lower all-cause and MS-related costs.Conclusion: With similar outcomes across DMT administration routes, initiating the least costly DMT may be warranted for many patients. In newly treated MS patients, the need exists to improve adherence and persistence.Keywords: administrative claims, healthcare costs, treatment adherence and compliance, drug administration routes |
