Abstract

Abstract: Background: Hip fracture risk is high in young people with multiple sclerosis (MS), but has not been examined in an institutionalized aging population with MS. Objective: We aimed to compare the hip fracture risk in nursing home (NH) residents with and without MS; and (2) examine risk factors for hip fracture in those with MS. Methods: We conducted a retrospective cohort study using national NH clinical assessment and Medicare claims data. Participants included age-, sex- and race-matched NH residents with/without MS (2007–2008). Multivariable competing risk regression was used to compare 2-year hip fracture risk, and to examine risk factors. Results: A total of 5692 NH residents with MS were matched to 28, 460 without MS. Approximately 80% of residents with MS vs. 50% of those without MS required extensive assistance in walking at NH admission. The adjusted incidence rate of hip fracture was 7.1 and 18.6 per 1000 person-years in those with or without MS, respectively. Wandering and anxiolytic exposure were the main hip fracture risk factors in transfer independent residents with MS; while pneumonia and antidepressant use were the main factors in dependent residents with MS. Conclusions: In contrast to prior comparisons from non-NH populations, the incidence of hip fracture was lower in NH residents with MS as compared with matched controls. Residents with MS were much more functionally dependent, which likely explains these findings. Fracture prevention strategies should focus on fall prevention in independent residents; and possibly improvement of health status and facility quality of care in dependent residents.
