Hip fractures are a danger to an individual's mobility, independence and ability to live in the community. When patients have a cognitive impairment (such as dementia or delirium) they do not recover as well or go back to their homes as often as those patients who do not have a cognitive impairment. Therefore, our team developed a rehabilitation model to care for patients with hip fractures, and specifically for those patients with CI. The model of care is called the Patient Centred Rehabilitation Model of Care (PCRM-CI). This 3 year study will focus on comparing the new model with usual rehabilitation care. This study will also focus on understanding the factors that could influence the use of the model on new rehabilitation units. The investigators hypothesize that patients who have received the new model of care will have better mobility outcomes over time. The investigators will collect data in 2 hospitals, 70 patients receiving the usual care and 70 patients receiving the care in the new model. The team will invite 60 staff and their unit managers as well. This study will help decision makers to use research findings to make better decisions about care of older Canadians.
