Comorbidity increases the risk of hospitalizations in multiple sclerosis.

ABSTRACT:

Objective

We aimed to evaluate the association between comorbidity and rates of hospitalization in the multiple sclerosis (MS) population as compared to a matched cohort from the general population.

Methods

Using population-based administrative data from the Canadian province of Manitoba, we identified 4,875 persons with MS and a matched general population cohort of 24,533 persons.
