Abstract

Study Design

Retrospective cohort study.

Purpose

The purpose of this study was to assess the rate of blood transfusion after cervical fusion surgery, and its effect on complication rates.

Overview of Literature

Cervical spine fusions have gained interest in the literature since these procedures are now ever more frequently being performed in an outpatient setting with few complications.

Methods

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent cervical fusion from 2010 to 2013. Multivariate regression analysis was used to determine postoperative complications associated with transfusion and cervical fusion.

Results

We identified 11,588 patients who had cervical fusion between 2010 and 2013. The rate of blood transfusion following cervical fusion found to be 1.47%. All transfused patients were found to have increased risk of venous thromboembolism (TBE) (odds ratio [OR], 3.19; 95% confidence interval [95% CI], 1.16-8.77), myocardial infarction (MI) (OR, 9.12; 95% CI, 2.53-32.8), increased length of stay (LOS) (OR, 28.03; 95% CI, 14.28-55.01) and mortality (OR, 4.14; 95% CI, 1.44-11.93). Single level fusion had increased risk of TBE (OR, 3.37; 95% CI, 1.01-11.33), MI (OR, 10.5; 95% CI, 1.88-59.89), and LOS (OR, 14.79; 95% CI, 8.2-26.67). Multilevel fusion had increased risk of TBE (OR, 5.64; 95% CI, 1.15-27.6), surgical site infection (OR, 16.29; 95% CI, 3.34-79.49), MI (OR, 10.84; 95% CI, 2.01-58.55), LOS (OR, 26.56; 95% CI, 11.8-59.78), and mortality (OR, 10.24; 95% CI, 2.45-42.71). Patients who had anterior cervical discectomy and fusion surgery and received a transfusion had an increased risk of TBE (OR, 4.87; 95% CI, 1.04-22.82), surgical site infection (OR, 9.73; 95% CI, 2.14-44.1), MI (OR, 9.88; 95% CI, 1.87-52.2), increased LOS of more than 2 days (OR, 28.34; 95% CI, 13.79-58.21) and increase in mortality (OR, 6.3; 95% CI, 1.76-22.48). While, transfused patients who had posterior fusion surgery had increased risk of MI (OR, 10.45; 95% CI, 1.42-77.12) and increased LOS of more than 6 days (OR, 4.42; 95% CI, 2.68-7.29).

Conclusions

Our results demonstrate that although cervical fusions can be done as outpatient procedures special precautions and investigations should be done for patients who receive transfusion after cervical fusion. These patients are demonstrated to have higher rate of MI, TBE, wound infection and mortality when compared to those who do not receive transfusion.
