Filter by:1. RATIONALE The unique characteristic of our study lies in the attempt to reverse the functional impairment experienced by sarcopenic patients with hip fracture using nutritional intervention. What makes this study different from prior studies is that it will be conducted in a hospital setting, unlike most prior studies, which were conducted in a community setting. The association between muscle mass and strength, inflammatory indices, and functional impairment versus dependence and fragility will also be measured. 2. HYPOTHESIS The hypothesis of our study is that nutritional intervention enriched in metabolites of essential amino acids (beta-hydroxy-beta-methylbutyrate) is effective for treating sarcopenia in elderly patients with hip fracture and improves functional level. 3. OBJECTIVES Primary objective is to assess functional improvement after nutritional intervention in sarcopenic patients with hip fracture, as measured using Barthel index. Secondary objectives will include: 1) to show the relationship between metabolic and inflammatory indices and sarcopenia; 2) to show how sarcopenia and its treatment influence the risk of fall; 3) to show muscle mass improvement; 4) to show increased strength; 5) to assess mortality and morbidity. 4. EXPECTED RESULTS The investigators expect to find that the supplemented group experiences throughout the study period a significant improvement in functional status (Barthel index), an increase in muscle mass, and a reduction in fat mass. An increased strength and a reduction in associated complications (falls) are also expected. The investigators hope to be able to show reductions in inflammatory indices and insulin resistance. To conclude, by improving muscle strength and mass the investigators expect to find a reduction in the disability and dependence of this population group.
Fragility fractures are one of the commonest injuries among elderly people in Hong Kong and account for 12% of the disease burden in elderly aged 65 or above. A good management healthcare program and training helps elderly to restore full functional level and prevent re-fracture in the following 2 years after primary fracture, but Hong Kong lacks of such program. Some reports from other countries pointed out a well-organized multi-disciplinary management programs are cost-effective to identify and treat osteoporosis, reduce the fracture rate, improve quality of life and raise awareness of fragility fracture. This study aims to compare the cost-effectiveness of multi-disciplinary management program with conventional care controls. The clinical effectiveness outcomes (re-fracture rate, fall rate, mortality, mobility, quality of life and specialist follow-up time) of the fragility hip fracture patients in New Territories East receiving the proposed management program will be compared with those from Kowloon Central with usual care as controls. The findings will provide useful data for the policy maker to evaluate the current clinical service for fragility fracture patients and consider the implementation of new multi-disciplinary management program into our healthcare system.
To evaluate the effect on gait and activity of a home based physiotherapy intervention 4-6 months after the fracture. The investigators hypothesis is that exercises performed after the initial rehabilitation, which focuses on specific components of gait control will improve gait and increase level of activity.
Hip fracture in the elderly is associated with excess mortality of 5 to 20%, and mobility problems that usually results in costly hospital stays and lengthy rehabilitation procedures. The purpose of this study is to compare the costs and effectiveness of three care models- acute/sub-acute, comprehensive, and routine care models for hip fractured elders in Taiwan.
Patients operated for hip fractures are older and have several conditions that have negative influences on the perioperative and postoperative prognosis. Hip fractures can also be painful, which is stressful for the physiology of the patient. Many old patients have received to little fluid intake. They often have diuretic therapy, which even worsens dehydration/hypovolemia. Some patients have to wait several days for surgery. Several studies have shown a high degree of complications and an increased mortality in this patient group. Early preoperative optimization can improve the outcome. The available methods for optimization of the patient are complicated and time consuming. The investigators wish with this study to try new approaches to find which patients still are dehydrated when they come to the operation ward. The aim is to measure the color and density of the urine as well as to register the the variability in the plethysmographic curve before spinal anaesthesia. These results will be compared to circulatory instability during and after surgery as well as to postoperative complications.
Osteoporotic hip fracture is common in elderly. As a result of aging population in Hong Kong, the total number of hip fracture cases is anticipated to increase substantially in the future, and therefore draw more resources in hospitals and healthcare cost. Osteoporotic hip fracture usually causes severe pain and takes long time (4-8months) to recover due to impaired healing capability in osteoporotic bones and limited mobility. Consequently, the patients will recover very slowly as a result of low physical activities to provide inadequate mechanical stimulation. It is also known that mechanical, vascular and biological factors are the keys for fracture healing. Low-magnitude, high-frequency vibration (LMHFV) treatment is a biophysical intervention to provide whole-body vibration signals for mechanical stimulation, which has been proven to be good in enhancing bone and muscle performance, as well as blood circulation. Our previous study of LMHFV on femoral fracture in rats showed acceleration of fracture healing, resulted from enhanced callus formation and maturation. Application of LMHFV on osteoporotic fractures could shorten the period of complete callus bridging by 30%. Our clinical trial on normal elderly also demonstrated improved muscle performance with good compliance, which is also a critical factor for fracture healing. In this study, the investigators therefore hypothesize that LMHFV can enhance hip fracture healing by enhancing fracture impaction, maintaining bone mineral density, enhancing muscle recovery, thus improving implant mechanical stability and rehabilitation in elderly patients. The hip fracture elderly patient will be recruited and randomized into control or treatment group. They will be assessed on the fracture healing at fixed time point. The findings of this study will provide very useful scientific data to support the application of LMHFV for hip fracture patients.The ultimate goal is to enhance the fracture healing and rehabilitation in elderly patients.
The objective of the study is to identify biochemical predictors of morbidity and mortality in patients suffering from hip fracture. For this purpose blood samples are collected prehospitally or in the emergency department in patients with a suspected hip fracture. During the hospital stay medical history, anesthesiological management recorded. In addition, american society of anesthesiology physiological score (ASA), revised cardiac risk index (RCRI), and POSSUM score is calculated. Morbidity and mortality is recorded " in house", after 30 days, after 4 months and after 1 year. Biochemical predictors of outcome will be evaluated with logistic regression analysis. Biochemical predictors include pro-brain natriuretic peptide, lactate, pro-calcitonin, adrenomedullin, copeptin, cystatin c. The predictive value of the potential markers will be compared to that of ASA, RCRI and POSSUM.
The primary purpose of this study is to illustrate whether there is a difference in the 6 minutes walking test in patients with hip fractures who have received 6 vs. 12 weeks of physical training after discharge from hospital.
Elderly with hip fractures are often frail and discharged from hospital after few days of hospitalisation. Hip fracture surgery is often associated with blood loss, where the patient is at risk of developing anaemia. Low haemoglobin level reduces the body's oxygen transport which causes impaired functional ability and strain on vital organs. Acute anaemia is worse tolerated in elderly, than in younger patients. Therefore this study aims to investigate whether there are effects of an expanded indication for blood transfusion in the frail elderly.
Specific Aims The long-term objective of this study is to examine the effectiveness of an intervention program for older patients with hip fracture. First, an intervention program for elderly patients with hip fracture will be developed and implemented, then, the effectiveness of the intervention program will be examined. The specific aims are as follows: 1. To develop a well conceived and feasible protocol of hospital discharge and sub-acute care that involves the coordinated work of health care professionals (physicians, surgeons, nurses, and physical therapists) and the informal caregivers. The feasibility of implementing such a protocol within the context of an intervention study subject to the constraints of the clinical setting (i.e., CGMH) will be evaluated in a pilot study. 2. To conduct a randomized clinical trial to evaluate the outcomes and costs associated with the proposed hospital discharge/sub-acute care protocol for elderly patients with hip fracture. Both experimental and case study methods will be used. Information on outcome indicators including clinical outcomes, quality of life, self-care ability, family caregiving outcomes, patient and caregiver satisfaction, and services utilization will be collected and compared between the control group and the experimental group. 3. To conduct a validation clinical trial to verify the results of the primary randomized clinical trial and increase the generalization of the study findings. 4. To estimate the cost of this care model and its variations for individual patients.
