Relationship Between Mortality Rates of Fractures in Different Sites and Several Factors in Elderly Patients

Официальное название

A Retrospective Study on the Relationship Between Mortality Rates of Fractures in Different Sites and Factors Such as Age, Metabolism, and Nutritional Status in Elderly Patients: A Single-center Retrospective Study

Обзор

Background and Purpose: As people age, bones become weaker and break more easily. Older adults (people 60 years and older) who break bones may face serious health problems and have a higher chance of dying compared to younger people. The location of the broken bone, a person's age, and overall health may affect the chances of survival. This study will conduct a retrospective analysis of medical records from geriatric patients who underwent surgical intervention for bone fractures at Shanghai Sixth People's Hospital between 2010 and 2019. The primary objective is to identify the key prognostic factors associated with post-operative mortality in this patient cohort. The study will retrospectively analyze the medical records of patients who meet all of the following criteria: Aged 60 years or older at the time of fracture diagnosis. Residents of Shanghai. Diagnosed with a fracture of the extremities (upper or lower limbs) or the spine. Underwent surgical intervention for the diagnosed fracture. The investigators will assess the following variables as potential prognostic factors for post-operative mortality: Fracture Characteristics: The anatomical location of the fracture (e.g., hip, spine, upper extremity, lower extremity). Patient Demographics: The patient's age at the time of injury. Physiological Status: Indicators of the patient's nutritional and metabolic health. Comorbidities: The presence and severity of pre-existing medical conditions. How investigators will do this study: This study is designed as a retrospective cohort analysis. Data will be systematically extracted from existing patient medical records. As an observational study, it involves no new interventions or modifications to patient care. The primary endpoint is all-cause mortality, which will be assessed at 1, 3, and 5 years post-operatively to determine long-term survival rates. Investigators will group participants by: The location of fracture (20 different bone locations); Age (60-65, 66-70, 71-75, 76-80, and over 80 years old); Nutrition and health status. Why This Study Matters: The results of this study will help doctors better understand which older patients are at higher risk after breaking a bone. This information could help healthcare teams provide better care and potentially save lives by identifying patients who need extra attention and treatment. Study Details: This study will examine records from approximately 2000 participants; All participants already received their treatment between 2010-2019; No new treatments or procedures will be performed; Participant's privacy will be completely protected; The study will take about 14 months to complete; This research will help improve care for older adults who experience bone fractures and may guide treatment decisions for future patients.
