Purpose: The aim of this study was to examine the prognostic impact of liver disease on mortality following hip fracture (HF).

Patients and methods: This nationwide cohort study, based on prospectively collected data retrieved from Danish registries, included all patients diagnosed with incident HF in Denmark during 1996-2013. Patients were classified based on the coexisting liver disease at the time of HF, ie, no liver disease, noncirrhotic liver disease, and liver cirrhosis. We computed 30-day and 31-365-day mortality risks. To compare patients with and without liver disease, we computed mortality adjusted hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using Cox regression controlled for potential confounders.

Results: Among 152,180 HF patients, 2,552 (1.7%) patients had noncirrhotic liver disease and 1,866 (1.2%) patients had liver cirrhosis. Thirty-day mortality was 9.4% among patients with noncirrhotic liver disease, 12.6% among patients with liver cirrhosis patients, and 9.7% among patients without liver disease. Compared to patients without liver disease, crude and adjusted HRs within 30 days following HF were, respectively, 0.96 (95% CI: 0.85-1.10) and 1.24 (95% CI: 1.09-1.41) for patients with noncirrhotic liver disease and 1.30 (95% CI: 1.14-1.48) and 2.25 (95% CI: 1.96-2.59) for those with liver cirrhosis. Among patients who survived 30 days post-HF, the 31-365-day mortality was 18.5% among patients with noncirrhotic liver disease, 26.4% among patients with liver cirrhosis, and 19.4% among patients without liver disease. Corresponding crude and adjusted HRs were, respectively, 0.95 (95% CI: 0.86-1.04) and 1.08 (95% CI: 0.99-1.20) for patients with noncirrhotic liver disease and 1.40 (95% CI: 1.27-1.54) and 1.91 (95% CI: 1.72-2.12) for those with liver cirrhosis.

Conclusion: Liver disease patients, especially those with liver cirrhosis, had increased 30-day mortality and 31-365-day mortality following HF, compared to patients without liver disease.
