Takeaway
Patients hospitalized with multiple sclerosis (MS) who have comorbid diseases may be at increased risk of short-term readmission.
Why this matters
Patients with MS regularly experience concomitant mental and physical health conditions and are hospitalized 1.5 times more often than the general population.
The presence of comorbid disease in patients with MS has been associated with delayed diagnosis and elevated self-reported disability.
Readmission rate is the primary target outcome for disease-modifying therapies in MS.
Comorbidities have been associated with increased readmission rates in patients with MS in Canada, but no data are available for patients in the United States.
