Abstract

OBJECTIVE: To evaluate the relationship between noncirrhotic hepatitis C virus (HCV) infection, perioperative complications, and discharge status in patients undergoing surgical procedures for hip fractures.

METHODS: A retrospective epidemiological study was performed, querying the National Hospital Discharge Survey. Patients were selected using the International Classification of Diseases-9 diagnostic codes for hip fracture and primary procedural codes for open reduction internal fixation, hemiarthroplasty, total hip arthroplasty, or internal fixation. Patients with concurrent cirrhosis, HIV, hepatitis A, B, D, or E were excluded. Pearson χ tests, independent-samples t test, and multivariable binary logistic regression were used for data analysis.

RESULTS: Two cohorts surgically treated for a hip fracture were identified and compared. The first cohort included 5377 patients with a concurrent diagnosis of noncirrhotic HCV infection (HCV+) and the second included 4,712,159 patients without a diagnosis of HCV (HCV-). The HCV+ cohort was younger and had fewer medical comorbidities, yet was found to have a longer length of hospital stay, higher rates of nonroutine discharge, and higher rates of complications than the HCV- cohort. Multivariate regression analysis demonstrated that HCV+ is an independent risk factor for perioperative complications and nonroutine discharge.

CONCLUSIONS: In conclusion, our study demonstrates a negative association between noncirrhotic HCV infection and hip fracture surgery outcomes. Caution and appropriate preparation should be taken when surgically treating hip fractures in HCV+ patients because of higher risk of perioperative complications and nonroutine discharge.

LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
