Overview
Brief Summary
Older adults suffering from a hip fracture are a significant concern, with higher incidence rates among women. Mortality rates post-hip fracture are alarming, with up to 8-fold increased risk within 3 months and significant percentages within 30 days and 12 months. Older adults with hip fracture face challenges in regaining pre-fracture level of function, especially those with cognitive impairment, which affects 25% to 40% of cases and increases mortality risk. While interventions exist, such as progressive strength training and structured exercise programs, patients with hip fracture don't consistently restore pre-fracture function, particularly in cognitively impaired patients, who are often excluded from studies. Limited evidence exists on effective management for this subgroup, with a lack of clarity on community-based rehabilitation. Although guidelines suggest exercise interventions for patients with mild to moderate cognitive impairment, the specifics remain uncertain due to insufficient research focused solely on this population.
This feasibility study aims to assess the practicality and safety of implementing a 12-week individualized, progressive exercise program for older adults with hip fracture and cognitive impairment in an outpatient setting. Additionally, the investigators seek to gather qualitative insights through observations and interviews regarding participants' experiences and the perceived value of rehabilitation post-hip fracture, particularly focusing on the exercise intervention provided.
Detailed Description
Background and overall aim. Approximately 7,000 people suffer a hip fracture in Denmark each year. A hip fracture is a traumatic event with high mortality rates, and older adults with hip fractures experience significant pain, a general decline in functional ability, and difficulty regaining the same level of function (e.g., being able to move freely without walking aids) as before the fracture. Older adults with hip fracture and signs of cognitive impairment constitute a subgroup, accounting for 25-40% of the total group. Dementia increases the likelihood of sustaining a hip fracture nearly threefold and results in higher mortality rates compared to the rest of the patient group. Furthermore, many individuals do not receive the treatment/training they are entitled to, despite being initially worse off than those without signs of cognitive impairment. There is limited research in this area because older adults with signs of cognitive impairment are often excluded from research studies. The few studies available suggest that older adults with hip fracture and signs of cognitive impairment may benefit from the same interventions provided to older adults with hip fracture who do not have signs of cognitive impairment. However, no randomized controlled trials have been conducted to investigate whether a systematic, well-planned, and personalized home training program is superior to the standard training offered in municipalities for older adults with hip fracture and signs of cognitive impairment. With this feasibility study it is intended to assess the practicality and safety of a 12-week individualized, progressive exercise program for older adults with hip fracture and signs of cognitive impairment in a municipality-based setting shortly after discharge from hospital. Hopefully, and if there are positive results from this feasibility study the investigators will proceed with a randomized controlled trial (in another study).

Outcomes
Primary Outcomes
The New Mobility Score
Time Frame: Baseline, 3 months, 6 months
The New Mobility Score is a composite score of the participant's ability to perform: indoor walking, outdoor walking and shopping, providing a score between zero and three (0: not at all, 1: with help from another person, 2: with an aid, 3: no difficulty) for each function, resulting in a total score from 0 to 9, with nine indicating a high functional level.
