Objective: To evaluate sociodemographic profile, clinical characteristics, disability and treatment status of multiple sclerosis (MS) patients in Turkey with respect to patient perspectives and expectations. Methods: A total of 2,176 MS patients participated in this cross-sectional questionnaire survey including items on sociodemographic, disease and treatment characteristics, daily life and perspectives and expectations. Results: Mean (SD) patient age was 36.4(9.4) years and 76.3% of patients were females. The numbness/weakness in the extremities (57.3%) was the most common presenting symptom. Overall, 56.8% reported treatment switch (due to attacks in 47.3%), while 22.2% reported physical disability and 39.7% reported work-related problems. Males had higher rate of MS-related physical disability (33.0% vs. 19.0%, p<0.001) than females. Use of an assistive device was a more common in patients with longer disease duration (≥15 years; 39.0%) and in those under IV treatment (64.0%). Nearly half of patients reported significant concerns related to uncertainty of the future and impaired quality of life as well as lack of hope for future improvement. The majority of patients reported that they would prefer less frequent SC injection dosing and 43.3% reported preference for monthly high-efficacy SC injection. Conclusion: This nationwide questionnaire-based study in Turkish MS patients revealed the altered disability status with respect to sociodemographic profile, and altered treatment expectations specific to the route of administration, in addition to significant concerns regarding the uncertainty of the future, impaired quality of life and lack of hope for future improvement in nearly half of patients.
