Hip fracture is a common injury of elder adults. To the best of our knowledge, there has been no specific population study to evaluate the risk of the postoperative death or complication for subjects with hip fracture in Taiwan. This study aims to calculate the incidence of hip fracture and to evaluate the postoperative mortality, medical and surgical complications among hip fracture in patients aged greater than 50 years from a nationwide database in Taiwan.
Materials and Methods:
This study analyzed the published national data from records of National Health Insurance claims. Subjects with surgery for hip fracture from 1999 to 2008 were selected and followed up to 2010. We included subjects with femoral neck fracture and trochanteric fracture. We also excluded subjects with open fracture, pathological fracture, major traffic accident and major trauma. Rates of incidence, mortality, standardized mortality ratios (SMRs) and complications were analyzed.
Results:
The incidence rates of hip fracture were 264.7 per 100,000 persons in 1999 to 262.2 per 100,000 persons in 2008. Overall, there were 78,819 deaths (55.4%) among 142,288 subjects. The 1-year mortality rates were 19.3% and 12.9% for male and female, respectively. The long-term mortality rates were 60.2% and 52.1% for male and female, respectively. Subject with hip fracture had a higher risk of death than the general population in Taiwan (standard mortality ratio, SMR = 2.7). The long-term incidence rates in male were 4.9%, 15.9%, 67.8% for medical, surgical, and overall complications, respectively. The long-term incidence rates in female were 3.7%, 17.2%, 61.7% for medical, surgical, and overall complications, respectively.
Conclusion:
This large-scale and long-term study reported the subsequent deaths, medical and surgical complications after surgery for hip fracture inpatients aged greater than 50 years in Taiwan. During the study period, the incidence of hip fractures showing the volatility of increase or decrease. The incidence of female was more than male each year. Hip fractures in patients who over the age of 50 had a higher mortality than the general population. Under the circumstance of postoperative survival, male survival situation was poor than female. This population in patients with preoperative who had more comorbidities, the higher risk of postoperative death will happen.
