Objective. To evaluate the association between clinical and demographic factors and health-related quality of life (HRQOL) among older people with multiple sclerosis (MS). Design. Cross-sectional survey-based study. Setting and participants. Patients with MS aged 60 years or older were recruited from 4 MS centers in Long Island, NY. Patients with severe cognitive impairment as determined by the health care practitioner were excluded. Participants were asked to complete 3 surveys at 3 different time-points. In the first survey, participants completed the Morisky Medication Adherence Scale and the Patient Multiple Sclerosis Neuropsychological Screening Questionnaire (P-MSNQ). The second survey was the Multiple Sclerosis Quality of Life-54 (MSQOL-54), and the third survey included the Beck Depression Inventory-II (BDI-II) and a disability status self-assessment scale. Cognitive function was measured at the time of recruitment using the Symbol Digit Modalities Test (SDMT). Analysis. The Andersen Healthcare Utilization model was used to structure the multivariate regression analysis. This model identifies multiple domains affecting quality of life, and the variables from the surveys were categorized according to domain: predisposing characteristics (demographic variables), enabling resources (caregiver support and living situation), needs (eg, health-related measures), and health behaviors (medication use, adherence). Main results. A total of 211 completed the first survey, 188 the second, and 179 the third. 80% were female and 95% were white. Average age was 65.5 (SD 5.6) years. 56% of respondents' self-reported scores on the SDMT classified them as cognitively impaired. Risk of neuropsychological impairment, depression, and disability status were significantly associated with a decreased mental and physical HRQOL. Significantly, there was a strong association between predisposing characteristics and QOL. Being widowed and remaining employed were the strongest predictors of better physical QOL and having an education level of high school or less was a predictor of lower mental HRQOL. Conclusion. Clinicians should measure HRQOL in older MS patients regularly and assess for depression and cognitive impairment.
