Predictors of 1-year Mortality After Hip Fracture Surgery in Patients with Age 50 years and Above: An Indian Experience.

Background: Hip fractures are considered as a major cause of mortality worldwide. Even after being the second most populous country in world and facing huge burden of hip fractures, there is scarcity of data from India. For the first time in Indian context, we analysed the predictors of mortality after hip fracture surgery in patients with age 50 years and above.

Materials And Methods: In this prospective cohort study, patients with age ≥ 50 years and having hip fractures presented to our institute from January 2018 through October 2018 were enrolled after meeting including and excluding criteria. Patients were followed-up for minimum 1 year after surgery. Association between 1-year mortality and different affecting variables were analysed. Significant variables were further analysed using logistic regression to find independent predictors.

Results: Out of 87 patients followed-up for 1 year, 25 patients died within 1 year of surgery. Age > 75 years, road traffic accident as mode of injury, delay in surgery > 48 h, > 2 co-morbidities, haemoglobin level ≤ 10 at the time of admission and osteoporosis are significantly associated with high mortality. When these significant variables were further analysed using logistic regression, age > 75 years and > 2 co-morbidities were only factors associated independently with high mortality.

Conclusion: In patients with age 50 years and above, following hip fracture surgery, age > 75 years and > 2 co-morbidities are the predictors of 1-year mortality when adjusted for other variable. A better designed multi-centric study can be more helpful in understanding the things in Indian context.
