Aims:
We conducted a questionnaire survey on Japanese MS patients to determine the relationship of fatigue, depression, and physical activity limitations with employment status.
Materials And Methods:
The study was conducted to assess the Patient Reported Outcome of MS patients treated with disease-modifying drug ≥6 months by recruiting MS patients from a web-based patient panel. Multiple regression analysis was performed by using items described in the Work Productivity and Activity Impairment Questionnaire-General Health Version 2.0 (WPAI-GH) and Fatigue Severity Scale (FSS), Quick Inventory of Depressive Symptomatology (Self-Report) (QIDS-SR), and Patient Determined Disease Step (PDDS).
Results:
Employment rates decreased after MS development and were more pronounced in the group with advanced physical disability with PDDS score ≥ 3. Health-related activity limitations were higher with advanced disability. In the analysis of the five subdomains of WPAI-GH by FSS score, the domains "due to health reasons," "disability rates during work," "overall work disability among the employed," and "health-related limitations' all increased with higher FSS scores." In WPAI-GH by QIDS-SR, the work disability rate was higher in the depressed group than in the normal group, and health-related activity limitations increased with greater depression.
Limitations:
This is a cross-sectional survey and data are based on PRO, hence are subjective and are collected based on patients' overall responses. Some bias could be attributed to memory and literacy rates as this is an online survey.
Conclusions:
The results suggested that the onset of MS prevented patients from working and forced them to resign from their jobs or give up full-time work. The rate of employment tended to be lower in the group with advanced limitations; suggesting that controlling the progression of limitations may lead to lower turnover, and the rate of health-related activity limitations was correlated with the degree of physical activity limitations, depression, and fatigue, respectively.
