Overview

Overview

Observational studies harnessed from real-world data in clinical practice have valuable implications in decision-making and can answer clinically relevant questions that have broad applicability. Clinical trial data, while valuable from a regulatory standpoint for approval of new medications, have more limited applications in the clinical setting. At Cleveland Clinic’s Mellen Center for Multiple Sclerosis Treatment and Research, we are using our large patient experience to better understand the effectiveness, safety, and patient experience with different treatment strategies in clinical practice. These studies leverage data from routine care that are not constrained by rigid clinical trials and are thus more generalizable and applicable to healthcare providers and patients living with multiple sclerosis (MS).

Some of these pragmatic observational studies use propensity score (PS) analysis to compare the safety and effectiveness of disease modifying therapies (DMTs) using real-world experiences. PS methods reduce the impact of confounding and certain biases that are inherent in observational studies, thereby approximating a randomized study design for determining treatment effect differences. Our investigators also use PS analysis to investigate MRI stability as a treatment target in MS and the long-term benefit of DMTs using the Knowledge Program, a Cleveland Clinic-developed database that collects longitudinal patient- and clinician-reported outcomes electronically.

We also harness observational data to describe the influence of various comorbidities on MS disease activity, analyze patient reported outcomes in patients transitioning from relapsing-remitting to secondary progressive MS, study the real-world experience of patients using technology-enabled neuroperformance testing, and describe the Mellen Center experience in DMT discontinuation to better understand disease and patient reported outcomes in older individuals living with MS. Altogether, through structured collection and analysis of clinical data, we are able to leverage real-world outcomes to answer clinically relevant questions and inform decision-making in routine practice.
