The association between deprivation and the access to disease modifying therapies for multiple sclerosis: An England wide community-based study in the UK MS Register.

Background: Deprivation can impact the access to health interventions in publicly funded health systems where cost is not the dominant barrier. In this study we examined whether deprivation affected the access to disease modifying therapies (DMTs) for multiple sclerosis (MS).

Methods: All English adults on the UK MS register with relapsing remitting MS who were diagnosed between 2010 and 2017, and after the age of 29 years were included. Deprivation was measured using postcode-based 2015 English index of multiple deprivation (IMD), which was divided into quintiles.

Results: A total of 1449 participants were eligible and 531/1449 (36.6%) received DMTs. Participants who lived in more deprived areas, based on their IMD scores, were significantly less likely to receive DMTs (odds ratio = 0.69, 95% Confidence interval = 0.49 to 0.98); barriers to housing and services contributed to this disparity. The Nagelkerke R value of these models showed that 2% of variation in accessing DMTs were dependant on deprivation.

Conclusions: Deprivation, as measured by IMD, negatively influences the access to DMTs in England. Our findings also suggest that the lack of access to local MS DMT clinics in deprived areas may contribute to this disparity.
