Objective We sought to investigate the postoperative morbidity and mortality rate of patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) undergoing elective anterior cervical fusion (ACF). Methods The Nationwide Inpatient Sample database from 2002−2011 was used to identify adult patients who underwent elective ACF for degenerative spine disease. Major complication rates and in-hospital mortality were compared among 3 groups—no kidney disease, CKD, and ESRD (dialysis dependent). A multiple logistic regression analysis was conducted to assess the independent effect of CKD and ESRD on outcome. Results There were 164,097 patients who met inclusion criteria. Among these, 1047 had CKD (0.64%) and 270 had ESRD (0.16%). After multiple logistic regression analysis, patients with CKD (odds ratio [OR] 1.51; 95% confidence interval [CI], 1.13–2.01; P = 0.005) and ESRD (OR 1.96; 95% CI, 1.20–3.21; P = 0.007) were significantly more likely to incur a postoperative complication when compared with patients without kidney disease (the reference group). Compared with patients without kidney disease, patients with CKD did not have higher odds of postoperative mortality (OR 2.25; 95% CI, 0.83–6.06; P = 0.108). However, in-hospital mortality was 15 times higher for patients with ESRD compared with patients without kidney disease (OR 15.2; 95% CI, 5.67–40.88; P < 0.001). Conclusion Chronic and end-stage renal disease may significantly increase the risk of postoperative morbidity and mortality after ACF. Future research into preoperative optimization of these patients and on the potential benefits of undergoing surgery until after renal transplantation is warranted.
