The Epidemiology and Impact of Comorbidity on MS in Canada (ECoMS) - Characterization of Comorbidities in MS
The aim of this project is to identify comorbidities among patients with MS, how these vary across sociodemographic groups, and differ from comorbidities in the general population.
-to identify comorbidities among patients with MS occurring with a frequency >=5%
-to determine which comorbidities occur with different frequencies than in the general population
-to determine temporal trends in MS-related comorbidities
-to describe the burden of illness related to MS in British Columbia; specifically, to estimate annual incidence and prevalence and trends in MS among British Columbia residents with stratification by age, sex, and geographic region of residence.
-to determine how comorbidity affects health-related quality of life (HRQoL) in MS
-to determine how psychiatric symptoms which do not meet formal diagnostic criteria affect HRQoL in MS
