Change in quality of life and predictors of change among patients with multiple sclerosis: a prospective cohort study

Qual Life Res. 2014 Apr;23(3):1027-37. doi: 10.1007/s11136-013-0535-1. Epub 2013 Oct 1.


Purpose: The aim of this study was to determine the changes in the health-related quality of life (HRQoL) and predictors of change among patients with multiple sclerosis (MS) at 3 and 6 years during the follow-up period.

Methods: A group of 109 consecutive MS patients (McDonald's criteria) referred to the Clinic of Neurology, Belgrade, were enrolled in the study. At three time points during the study (baseline, and at 3 and 6 years during the follow-up period), the HRQoL (measured by MSQoL-54), Expanded Disability Status Scale, and Hamilton Rating Scale for Depression and Fatigue Severity Scale were assessed.

Results: During the study period, 93 patients provided both follow-up assessments. Statistically significant deterioration in the HRQoL at each subsequent time point was detected for all scales of the MSQoL-54 except for the pain and change in health scales. A higher level of education was a significant prognostic factor for a better HRQoL on the cognitive function scale throughout the entire period of observation, while marital status (single, including divorced and widowed) and increased age at the onset of MS had significant predictive values of poorer quality-of-life scores on the overall quality-of-life scale at 6-year follow-up. Higher levels of physical disability and depression at baseline were statistically significant prognostic markers for deterioration in HRQoL for the majority of MSQoL-54 scales during the entire follow-up period.

Conclusions: Our study suggests that baseline demographic and clinical characteristics could be applied as prognostic markers of the HRQOL for patients diagnosed with MS.
