Objective: The aim of this study was to compare postoperative mortality and morbidities in patients with hip fractures undergoing surgery by Child-Pugh classes. Summary Background Data: Advanced cirrhosis is associated with increased mortality in several types of surgery, but the impact of severity of cirrhosis on postoperative outcomes in patients with hip fractures remain unclear. Methods: We analyzed data of patients with hip fracture within a large inpatient database. We performed three sets of 1:1 propensity-score matching for four groups: cases without cirrhosis, and Child-Pugh classes A, B and C. We compared in-hospital mortality, length of stay, hospitalization fee, rate of 30-day readmission and complications in the following three pairs: cases without cirrhosis vs Child-Pugh class A, Child-Pugh class A vs B, and Child-Pugh class B vs C. Results: Among 833,648 eligible cases, propensity-score matching created 1,065 pairs between cases without cirrhosis vs Child-Pugh class A, 1,012 pairs between Child-Pugh class A vs B, and 489 pairs between Child-Pugh class B vs C. In-hospital mortality did not differ between cases with cirrhosis and those with Child-Pugh A classification (1.69% vs 1.41%; RD -0.28%; 95% CI: -1.34%-0.78%). In-hospital mortality was significantly higher in patients with Child-Pugh B classification than in those with A classification (1.48% vs 5.93%; RD 4.45%; 95% CI: 2.79%-6.10%), and in those with Child-Pugh C classification compared with those with B classification (6.34% vs 28.43%; RD 22.09%; 95% CI: 17.54%-26.63%). Among cases with cirrhosis, those in more severe Child-Pugh classes had longer length of stay, higher hospitalization fees and higher ratio of complications, such as acute liver failure, upper gastrointestinal bleeding and sepsis. Conclusions: Our results could help to identify patients at high-risk of postoperative mortality and morbidity among those with both hip fracture and cirrhosis. Patients with Child-Pugh C classification may benefit from discussions about nonsurgical management, goals of care, and overall prognosis.
