Cirrhosis associated with increased complications and healthcare utilization following total shoulder arthroplasty.

INTRODUCTION

Cirrhosis is a known risk factor for morbidity and mortality following surgical procedures and has been associated with increased complications, hospital length of stay (LOS), and cost of admission following total joint arthroplasty. However, a paucity of literature exists evaluating the effect of cirrhosis on postoperative outcomes following total shoulder arthroplasty (TSA). The purpose of this study is to evaluate the short-term outcomes following elective primary TSA in patients with cirrhosis compared to matched controls.

METHODS

The Nationwide Readmissions Database was queried from 2016 to 2020 to identify patients who underwent elective primary TSA. Patients with a diagnosis of cirrhosis ( = 627) were matched in a 1:1 proportion to patients who did not have cirrhosis. Bivariate statistical analyses were performed to compare preoperative demographic and comorbidity data, postoperative outcomes, and hospital utilization metrics between the two groups. Following Bonferroni correction, an alpha value of 0.003 defined significance.

RESULTS

Patients with cirrhosis exhibited higher rates of postoperative medical and implant-related complications following primary TSA, including acute renal failure (6.3% vs 1.1%:  < 0.001), urinary tract infection (3.5% vs 0.6%;  < 0.001), transfusions (3.0% vs 0.2%;  < 0.001), acute respiratory distress syndrome (2.9% vs 0.2%:  = 0.002), surgical site infection (2.0% vs 0.2%:  = 0.001), dislocation (2.1% vs 0.0%:  < 0.001), and prosthetic loosening (1.5% vs 0.0%;  = 0.002). These patients also exhibited higher rates of all-cause complications (32% vs 9.2%:  < 0.001) and mortality (1.5% vs 0.0%;  = 0.002) within 180 days of surgery and had an increased cost of admission ($24,633 vs $18,500;  < 0.001) and LOS (2.6 vs 1.5 days;  < 0.001).

CONCLUSION

Patients with cirrhosis were found to have increased risk of medical and surgical complications, higher costs, and longer LOS following TSA. These findings can assist orthopedic surgeons in developing strategies in the preoperative period to mitigate complications in this at-risk patient group.
