Sickness absence and disability pension within different employment status in multiple sclerosis

Abstract

Abstract Introduction Limitations associated with Multiple Sclerosis (MS) can restrain work capacity and productivity, reducing the possibility to remain in work. Whilst access to sickness compensation might be an option, transitions to other types of employment, such as self-employment, might be considered. We aim to investigate the association of Sickness Absence (SA) and Disability Pension (DP) with employment status among people with multiple sclerosis (PwMS) before and after MS diagnosis compared with people without MS. Methods A prospective longitudinal study was conducted using Swedish register data of 2,779 MS patients diagnosed with MS in 2008-2012 in working ages (20-59 years) and 13,863 population-based matched references. Levels of SA and DP one year before and four years after MS diagnosis were analyzed. Risk of annual SA and DP levels of more than 180 days were compared among the MS patients and references and, their different types of employment, by means of Cox proportional hazard models and adjusted for socio-demographic variables and SA and DP before MS diagnosis. Results In general, people with MS had higher levels of SA and DP before and shortly after MS diagnosis compared to references. PwMS showed a significantly higher probability of reaching over 180 days of SA (Hazard Ratio [HR]=4.89, 95% Confidence interval [CI]=4.43-5.40) and over 180 days of DP (HR = 6.31, 95% CI = 5.46-7.30)) than the references, regardless of type of employment. Moreover, when compared to employed references, self-employed PwMS had similar likelihood to reach over 180 days of SA than employed PwMS, (HR = 4.27, 95% CI = 3.81-4.77) and (HR = 3.83, 95% CI = 2.73-5.38), respectively. In contrast, self-employed references showed less probability (HR = 0.49, 95% CI = 0.31-0.78) to reach over 180 days of SA compared to the employed references. Conclusions In contrast to references, employed and self-employed PwMS had similar probabilities of reaching over 180 days of SA. Key messages This study emphasizes that in Sweden also self-employed have access to sickness compensation, independently of employment status condition. Access to sickness compensation is utilized by PwMS.
