Increased incidence, morbidity, and mortality in cirrhotic patients with hip fractures: A nationwide population-based study

Objectives: Hip fractures mostly require surgical treatment and are associated with increased health-care costs and mortality rates. Patients with cirrhosis have low bone marrow density and inferior immune status which contribute to a higher fracture rate and higher surgical complication rate. This population-based study evaluated the prevalence, complication, and mortality rates due to hip fractures in cirrhotic patients. Methods: Taiwan National Health Insurance Research Database data were used. The study group included 117,129 patients with hip fractures diagnosed from 2004 to 2010, including 4048 patients with cirrhosis. The overall prevalence, morbidity, and mortality rates of the cirrhosis group with hip fractures were compared with the rates of a general group with hip fractures. Results: The cirrhosis group patients were younger than the general group patients (71.2 vs. 73.96 years, p < 0.001). The annual incidence of hip fractures in the cirrhosis and general groups was 46–54 and 7–7.5 per 10,000 person-years, respectively, with an incidence rate ratio of 6.95 (95% confidence interval 6.74–7.18). The rates of infection, urinary tract infection, and peptic ulcer disease were higher in the cirrhosis group (3.46% vs. 1.91%, 9.56% vs. 9.11%, and 8.05% vs. 3.55%, respectively; all p < 0.001). The mortality rate after hip fracture was also higher in the cirrhosis group than in the general group (within 3 months: 8.76–12.64% vs. 4.96–5.30% and within 1 year: 29.72–37.99% vs. 12.84–14.57%). Conclusion : Cirrhotic patients with hip fractures were relatively younger; had a seven times higher annual hip fracture incidence; had higher complication rates of infection, urinary tract infection, and peptic ulcer disease; and had two to three times higher a mortality rate at 3 months and 1 year. Clinicians should pay particular attention to the possibility of osteoporosis and hip fractures in patients with liver cirrhosis. Level of Evidence: Level III, case–control study
