Introduction: Comprehensive epidemiologic data for multiple sclerosis (MS) in Poland are limited. Aim of the research: To analyse patient-reported quality of life and selected clinical and socio-demographic factors of patients registered in the Świętokrzyskie Cohort of the Polish Registry of Multiple Sclerosis (RejSM). Material and methods: Participants were residents of Świętokrzyskie Province, and the data were collected between January 1 st 2014 and December 31 st 2015 by the RejSM web portal. After registration by doctors, the respondents assessed their quality of life individually using the Polish language versions of self-assessment questionnaires, the EuroQol (EQ-5D and EQ-VAS), and the Multiple Sclerosis Impact Scale (MSIS-29). Results: Of 1525 registered patients, 765 agreed to perform self-assessments of life quality and were included in the study. The mean degree of disability measured with the Expanded Disability Status Scale (EDSS) was 3.8 ±2.3. The mean EQ-5D index score was 0.78 ±0.28, and the mean EQ-VAS score was 65.6 ±23.8. Assessment score with MSIS-29 averaged 86.4 ±22.4 (64.2 ±19.6 for physical state and 24.7 ±7.8 for mental state). Only 34.7% of respondents were economically active. Lower quality of life was significantly associated with higher disability scores (p < 0.001), age over 40 years (p < 0.001), longer disease duration (p < 0.001), no access to therapy (p < 0.001), and unemployment (p = 0.002). No correlation was found between life quality and sex, course of disease, level of education, place of residence, or family status.
Conclusions:The main factors decreasing life quality among patients in Świętokrzyskie Province are advanced disability, old age, long disease duration, and limited access to both employment and immunomodulatory treatment.
