The Impact of Frailty on Patients Undergoing Liver Resection for Colorectal Liver Metastasis

Background The aim of this study is to assess the impact of frailty on short-term outcomes after hepatectomy for colorectal liver metastasis (CRLM). Methods Patients were identified using the National Surgical Quality Improvement Program (NSQIP). Patients were divided into 3 categories using the 5-item Modified Frailty Index (mFI). Results There were 5230 patients included. 52%, 35%, and 13% had mFI scores of 0, 1, and >= 2 respectively. Patients with a >= 2 mFI score were more likely to experience minor complication (OR 1.34, 95% CI 1.06-1.69), major complication (OR 1.56, 95% CI 1.15-2.12), readmission (OR 1.55, 95% CI 1.12-2.14), unfavorable discharge (OR 2.48, 95% CI 1.62-3.80), 30-day mortality (OR 3.02, 95% CI 1.02-8.95), prolonged length of stay (OR 1.47, 95% CI 1.18-1.83), and bile leak (OR 1.51, 95% CI 1.02-2.24). Conclusion Frailty is associated with increased post-operative complications. The 5-item mFI can guide risk stratification, optimization, and counseling.

Automated summary

This study aimed to assess the impact of frailty on short-term outcomes after hepatectomy for colorectal liver metastasis (CRLM). Using the Modified Frailty Index (mFI), patients were divided into categories. The study found that frailty is associated with increased post-operative complications.
