Hypothesis
What factors influence survival in patients aged 90 years and older undergoing surgery for proximal femoral fractures?
Conclusion
Cognitive impairment, low Geriatric Nutritional Risk Index, and prolonged hospital stay are significant predictors of 1-year mortality in nonagenarian patients with proximal femoral fractures.
Supporting Evidence
- The 12-month mortality rate was 28.8%.
- Patients with cognitive impairment had a significantly higher mortality rate.
- A low Geriatric Nutritional Risk Index was associated with increased mortality.
- Longer hospital stays correlated with higher mortality rates.
- Multivariate analysis identified key predictors of mortality.
Takeaway
Older people who break their hip and have memory problems or poor nutrition are more likely to not survive for a year after surgery.
Methodology
This retrospective study analyzed 285 patients aged ≥90 years who underwent surgery for proximal femoral fractures, assessing various factors related to their survival.
Potential Biases
Potential selection and information biases due to the retrospective nature of the study.
Limitations
The study's retrospective design may introduce biases, and it did not include a comprehensive range of comorbidities.
Participant Demographics
The cohort comprised 43 males and 242 females, with a mean age of 93.2 years.
