Objectives: This study aimed to investigate the risks and impacts associated with fractures, osteoporosis, frailty, physical function, and dementia in older adults in community and LTC setting. The study aims to identify important factors influencing these health issues and identify strategies for improving management and outcomes.
Methods: The research integrates data from three primary sources: Project 1 (ICES Data Repository): Healthcare utilization and administrative databases were linked using unique, encoded identifiers from the ICES Data Repository to estimate hip fractures and osteoporosis management among adults aged 66 and older from April 1, 2014, to March 31, 2018. Osteoporosis management was assessed through pharmacotherapy records. Sex-specific and age-standardized rates were compared based on pre-fracture residency and discharge location (e.g., LTC to LTC, community to LTC, or community to community). Fracture risk was determined using the Fracture Risk Scale (FRS). Project 2 (Canadian Longitudinal Study on Aging - CLSA): Participants aged 45 to 85 years who completed both the baseline and three-year follow-up assessments were included. Outcomes examined include frailty (Fried Frailty Phenotype), and physical function limitations. MSK conditions were self-reported diagnosis by a health care professional and included rheumatoid arthritis (RA), osteoarthritis (OA), low-back pain, osteoporosis, and related fractures. Project 3: The review employed Arksey and O'Malley's framework, guided by Joanna Briggs Institute methodology and PRISMA-ScR guidelines. A comprehensive search strategy was implemented across MEDLINE, EMBASE, CINAHL, and grey literature. Independent reviewers used Covidence software for study selection and data extraction. A narrative synthesis was conducted to summarize findings, identify patterns, and highlight gaps in the literature.
Findings: We found increasing hip fracture rates and low osteoporosis treatment in LTC settings, highlighting to the need for improved screening and management of osteoporosis treatment in LTC. In community, hip fracture rates decreased. We found that older adults with musculoskeletal (MSK) conditions
at baseline were more likely to experience frailty at the three-year follow-up compared to those without MSK conditions. However, this association was not significant in the unadjusted analysis. Individuals with cognitive decline experience worse outcomes following hip fractures, underscoring the need for integrated care addressing both physical and cognitive health.
Conclusion: Hip fractures, frailty, physical function decline, and cognitive decline are prevalent and interrelated issues among older adults aged 65 and older. These findings underscore the need for improved screening and integrated care strategies to enhance management and prevention of these complex health challenges. / Thesis / Doctor of Philosophy (PhD) / Aging is associated with increased risks of osteoporosis, fractures, frailty, physical function decline, and dementia, particularly for older adults in long-term care (LTC). This study explores these health challenges by analyzing data from three key sources: ICES, the Canadian Longitudinal Study on Aging (CLSA), and a scoping review of patient-important outcomes following a hip fracture in older adults with cognitive impairment or dementia. First, we found increasing hip fracture rates in LTC and among older adults living in community at time of fracture and transferred to LTC post fracture. Osteoporosis treatment was low among high fracture risk LTC residents. Second, we found that older adults with baseline musculoskeletal (MSK) conditions (osteoporosis, fractures, osteoarthritis (OA), rheumatoid arthritis, and back pain) were more likely to become frail and have physical function limitation over three years compared to those without MSK conditions. However, after adjusting for covariates, these associations were no longer significant. Among the individual MSK conditions, we found older adults with only OA and osteoporosis-related fractures to be significantly associated with physical functional limitations. Lastly, we found that following a hip fracture, older adults with cognitive impairment or dementia have poorer functional outcomes, reduced quality of life, higher hospitalization and mortality rates, and are significantly more likely to be institutionalized compared to older adults without cognitive impairment or dementia, highlighting the need for integrated care that addresses both physical and cognitive health
