Background: Multiple sclerosis (MS) is the most common cause of non-traumatic neurological disability affecting young adults during their best working years. Previous studies have shown that approximately two-thirds of patients with MS (PwMS) are unable to retain employment in the long term, and many retire soon after the diagnosis. However, it is not known, how the rate of retirement has changed over the decades, especially after the introduction of disease modifying therapies (DMTs). The year 1995 was selected as a division point because DMTs have been increasingly available ever since. Objective: To evaluate the change in retirement rate due to MS and to present risk factors for early retirement. Methods: A retrospective survey of all PwMS treated at the Department of Neurology, Kanta-Häme Central Hospital, Finland between 1978 and 2015, was conducted. The population was divided into two groups: those diagnosed before year 1995 and those diagnosed thereafter. A Kaplan-Meier analysis was performed to evaluate the time from diagnosis to beginning of a pension in both groups. Crude incidence rates, incidence rate differences as well as age and multivariable adjusted Cox proportional hazard regression analysis were calculated for all pension predictors collected. Results: A total of 484 PwMS were identified, 140 of whom were diagnosed before the year 1995 and 344 after. Actual retirement rates were 88 (63%) before the year the year 1995 and 111 (32%) after, respectively. The hazard for disability pension diminished in PwMS diagnosed after the year 1995 compared to those diagnosed before, HR 0.41 (95% confidence interval 0.31-0.55). The median time from diagnosis to retirement was 8.3 years in the group diagnosed before year 1995 and 11.1 years in the group diagnosed later. Male sex and age were statistically significant risk factors in relapsing-remitting MS, HR for male sex 1.8 (95% confidence interval 1.18-2.75) and for age 1.1 (95% confidence interval 1.07-1.12). Only age was a risk factor in progressive MS with HR 1.09 (95% confidence interval 1.07-1.11). In subgroup of relapsing-remitting MS, not using disease modifying therapies was a statistically significant risk factor, HR 1.89 (95% confidence interval 1.19-3.01). Conclusion: The rate of retirement due to MS in Finland has decreased significantly since 1995 and the median time from diagnosis to retirement has become longer. Not using disease modifying therapies for relapsing remitting MS was identified as one risk factor for losing ability to work prematurely.
