ABSTRACT

Objective:
The incidence of hip fractures in South Korea is increasing, and it is also a socioeconomic burden. This study analyzed the factors affecting the mortality and complications of hip fracture patients.
Method:
The Korean National Hospital Discharge In-depth Injury Survey was used to investigate the sex, age, Charlson comorbidity index (CCI), insurance type, pre-operation length of hospital stay, fracture type, operation type, and the number of beds in the hospital from 2009 to 2018.
Results:
A total of 3,898 patients were enrolled. There were statistical differences in sex, age, insurance type, and CCI divided into the survival and the non-survival groups. There were statistical differences in age, CCI, and the number of beds divided into the group without complications and the group with complications. Multivariate logistic regression analysis revealed that men, age > 84 years (odds ratio [OR], 3.064; 95% confidence interval [CI], 2.000-4.692), medical aid (OR, 2.724; 95% CI, 1.672-4.436), and CCI≥3 (OR, 3.968; 95% CI, 2.555-6.162) were risk factors for the mortality and also revealed that age > 84 years (OR, 3.195; 95% CI, 2.18-4.683) and CCI≥3 (OR, 5.773; 95% CI, 4.174-7.986) were risk factors for the complications.
Conclusion:
In this study, the factors affecting the mortality were men, old age, medical aid, and underlying diseases, and the factors affecting complications were old age and underlying diseases.
