Transition to secondary progressive multiple sclerosis: The consequences for patients and healthcare systems, a...

Transition to secondary progressive multiple sclerosis (SPMS) from relapsing-remitting MS (RRMS) is an expected part of the disease trajectory for most patients. However, the transition is challenging to identify due to the gradual nature of progression, and the complications of superimposed relapses, comorbidities, and natural variability in symptoms. This healthcare professional (HCP) survey sought to characterize the transition to and management of SPMS in UK clinical practice.

Telephone interviews with 20 neurologists and MS specialist nurses from England and Scotland gathered quantitative and qualitative responses. Numerical analyses and theoretical thematic methods were used to identify key emerging themes.

The burden SPMS imposes on patients and caregivers was a major theme; discharge from specialist services is common, leading to a sense of abandonment. Respondents acknowledged substantial hesitancy toward identifying SPMS, predominantly due to restricted options of licensed and reimbursed disease-modifying therapies (DMTs) for SPMS compared with RRMS. Currently, HCPs continue DMTs under a label of RRMS, even after recognition of progression. This survey identified MS to be unusual in comparison with other disease areas in that reimbursement guidelines have a direct impact on clinicians' decisions around disease staging. Respondents suggested reimbursed DMTs proven to slow disability progression in SPMS will create a step-change in identifying SPMS, providing rationale to acknowledge progression earlier while removing key obstacles to identification. To aid this change, respondents identified a need for SPMS-specific diagnostic guidance, despite substantial divergence in implementation of current guidance.

In contrast to the current heterogeneity, a more structured and standardized approach to the identification of SPMS, along with guidelines on treatment, will ensure patients can maximally benefit as treatment options for SPMS evolve.
