Insights
Hip fracture surgery outcomes are impacted by patient age, medical history, and timely intervention. Delays over 48 hours significantly increase 1-year mortality risk in elderly patients following hip fracture surgery.
Area of Science:
- Geriatric Medicine
- Orthopedic Surgery
- Public Health
Background:
- Hip fracture (HF) is a significant health concern in the elderly, with millions affected globally each year.
- The incidence of hip fractures is projected to increase due to global population aging.
- Identifying risk factors for hip fracture mortality is crucial for improving patient outcomes.
Purpose of the Study:
- To identify independent risk factors associated with 1-year mortality after hip fracture surgery.
- To analyze the impact of surgical timing on mortality rates in hip fracture patients.
Main Methods:
- An observational, prospective, single-center study was conducted at Amiens University Hospital.
- Data were collected from 309 patients who underwent hip fracture surgery between June 2016 and June 2017.
- Statistical analysis, including univariate analysis and Cox modeling, was used to determine mortality risk factors.
Main Results:
- The 1-year mortality rate after hip fracture surgery was 23.9%.
- Independent risk factors for 1-year mortality included advanced age (HR 1.059), a Lee score of 3 or higher (HR 1.52), and delayed surgery (time to surgery > 48 hours, HR 1.057).
- Over half of the patients (58.6%) experienced surgical delays exceeding 48 hours.
Conclusions:
- Age, pre-existing medical conditions (indicated by Lee score), and delayed surgical intervention are significant predictors of 1-year mortality in hip fracture patients.
- Optimizing surgical timing, ideally within 48 hours of admission, is essential for reducing mortality.
- These findings highlight the need for prompt management of hip fractures in the elderly to mitigate adverse outcomes.
Abstract:
Hip fracture (HF) remains a main issue in the elderly patient. About 1.6 million patients a year worldwide are victims of a HF. Their incidence is expected to rise with the aging of the world's population. Identifying risk factors is mandatory in order to reduce mortality and morbidity. The aim of the study was to identify risk factors of 1-year mortality after HF surgery. We performed an observational, prospective, single-center study at Amiens University Hospital (Amiens, France). After ethical approval, we consecutively included all patients with a HF who underwent surgery between June 2016 and June 2017. Perioperative data were collected from medical charts and by interviews. Mortality rate at 12 months was recorded. Univariate analysis was performed and mortality risk factors were investigated using a Cox model. 309 patients were analyzed during this follow-up. Mortality at 1 year was 23.9%. Time to surgery over 48 hours involved 181 patients (58.6%) while 128 patients (41.4%) had surgery within the 48 hours following the hospital admission. Independent factors associated with 1-year mortality were: age (HR at 1.059 (95%CI [1.005-1.116], p = 0,032), Lee score ≥ 3 (HR at 1,52 (95% CI [1,052-2,198], p = 0.026) and time to surgery over 48 hours (HR of 1.057 (95% CI [1.007-1.108], p = 0.024). Age, delayed surgical (over 48 hours) management and medical history are important risk factors of 1-year mortality in this French cohort.
