Aging and age-related frailty are important public health problems. There is a need to develop rehabilitation interventions to reduce the prevalence and disabling effects of frailty. This thesis reports the rationale and design of two studies and findings of three studies aimed to optimize health outcomes of frail older adults and their caregivers. The second chapter describes the protocol of the first network meta-analysis to determine the comparative effect of interventions targeting the prevention or treatment of frailty. In the third chapter, the results of frailty network meta-analysis were presented and 89 RCTs were included. The review shows that physical activity and medication management are the most effective frailty interventions. The fourth chapter describes a protocol of pilot randomized controlled trial (RCT) to examine a preoperative multi-modal frailty intervention in pre-frail/frail older adults undergoing elective joint replacements.
The fifth chapter describes the results of a subgroup analysis of a RCT examining the effect of complex primary care intervention to support caregivers of frail older adults. There were no differences between caregivers of frail older adults and non-caregivers in quality of life, social support, hospitalization, and emergency department visits. The sixth chapter examines the construct validity and discriminative properties of the fracture rating scale (FRS) (a tool designed for fracture risk assessment in long term care (LTC)). The FRS is a valid tool for identifying LTC residents at different risk levels for hip fracture in three Canadian provinces.
The work presented in this thesis is proposing and examining the comparative effect of frailty interventions, a preoperative frailty intervention/ model, a primary care intervention to identify and support caregivers, and a predictive tool to optimize care planning of LTC residents. These findings will support the rehabilitation and care program for older adults and their caregivers and improve their health outcomes. / Thesis / Doctor of Philosophy (PhD) / There is a need to develop rehabilitation interventions to reduce the prevalence and disabling effects of frailty. This thesis reports the rationale and design of two studies and findings of three studies aimed to improve health outcomes of frail older adults and their caregivers. The second and third chapters of this thesis describe the protocol and results of a review aims to identify the effect of interventions targeting frailty, the review found that physical activity and medication management are the most effective frailty interventions. The fourth chapter describes a study examining the possibility of comparing a complex intervention to usual care in frail older adults undergoing joint replacements. The fifth chapter showed that a primary care intervention did not improve the caregivers’ health outcome. The sixth chapter presents the fracture rating scale, a valid tool for identifying Long-term care residents at risk of hip fracture in three Canadian provinces. These findings aim to improve the care for older adults and their caregivers.
