Hip Fractures (i.e. Femoral Neck or Intertrochanteric Hip Fractures)

To address the difficulties and problems currently facing large-scale clinical cohort studies in China, and on the basis of the existing project "Construction of Clinical Registration Database and Risk Assessment System for Osteoporosis and Osteoarthritis" under the National Key R\&D Program of the Ministry of Science and Technology, this project aims to target elderly hip fracture-an international public health issue-by collaborating with 38 hospitals across the country to jointly establish the largest specialized cohort for elderly hip fracture in China, thereby providing a data platform and technical support for multicenter clinical cohort studies on elderly hip fracture.

Hip fracture is a common injury in elderly patients, often requiring surgical treatment. However, these patients frequently experience severe postoperative pain, which can delay mobility and recovery, and increase the risk of complications such as delirium, pneumonia, and prolonged hospital stay. The fascia iliaca compartment block (FICB) is a regional anesthesia technique that has been shown to provide effective pain relief for hip fracture patients. This study aims to investigate whether early administration of FICB, performed upon hospital admission before surgery, can improve postoperative rehabilitation outcomes in elderly patients with hip fracture. This is a prospective, randomized, controlled study. A total of 144 elderly patients with hip fracture will be randomly assigned to either the FICB group or the control group. The FICB group will receive ultrasound-guided FICB after being admitted to the orthopaedic ward, while the control group will receive standard analgesic care once inside the operating room. The primary outcome measure is Quality of Recovery-15 score (QoR-15 score) 24 hours post-surgery. Secondary outcomes include: QoR-15 score at 48 hours postoperatively, NRS scores and sleep duration and quality scores at preoperative and various postoperative time points, total perioperative consumption of opioids and other analgesic drugs, extubation time and emergence agitation during anesthesia recovery period, incidence of delirium from postoperative period to before discharge, length of hospital stay, and overall satisfaction score with pain management. The hypothesis of this study is that early FICB intervention, compared to standard care, will lead to better pain control, earlier mobilization, shorter hospital stay, and improved overall postoperative recovery in elderly patients with hip fracture.

Title Improving shared decision-making in older hip fracture patients living with frailty Aim To use routinely information normally collected by the NHS, and interviews with patients, families, and healthcare professionals, to produce an aid to help patients make decisions about hip fracture treatment that reflects what is important to them. Background Breaking a hip after a fall is common in older adults. The risk of dying is high after a hip fracture, especially if the person does not have surgery. Most UK patients have surgery even if they are very frail. Patients who are at a very high risk of dying still have surgery to help control the pain. However, this is not the same in all countries and recent studies show pain can be well controlled with medications and nerve-numbing drugs. Whilst the risk of dying is still much higher without surgery, to some frail older adults there are more important things to them than living longer like being able to walk and look after themselves. Some people may choose end-of-care instead of an operation if surgery means they won't be able to do these things afterwards. To help frail older people make the decision that is best for them, they need information about all treatment options and what their life is likely to be like after. This information needs to be easy to understand. Why the research is important This research will give frail older people with hip fractures the information they need to make decisions that focus on what is most important to them. We will make a guide to present the information in a way that is easy to understand and will help patients make decisions alongside healthcare professionals. Design We will complete 4 Work Packages (WPs): WP1: What do we already know about the link between frailty and the ability for older people to move and look after themselves after hip fracture? • We will review all current studies that look at what frail older peoples' lives are like after having a hip fracture and combine all the information in these studies. This will stop us from repeating work already done and show us any gaps in knowledge. WP2: Can we use how frail someone is and other information to predict their ability to move and look after themselves after a hip fracture? • We will use data the NHS collects to explore links between frailty, health and social issues, and a person's ability to move, walk, and care for themselves after hip fracture. I will see if these factors predict which people will do better after a hip fracture. WP3: What factors affect treatment decisions in frail adults with a hip fracture? • We will interview older hip fracture patient with frailty, families, and healthcare staff to explore how decisions are made about hip fractures and how we can improve this. WP4: Creating and testing an aid to help older patients with frailty make decisions about hip fracture treatment • We will work with patients to design a decision aid to improve shared decision-making in hip fracture care. We will test out the aid on orthopaedic wards in Southampton and improve it based on feedback.
