(HealthDay News) – The readmission rate following anterior cervical discectomy and fusion (ACDF) is 2.5%, and hypertension may increase the likelihood of readmission, according to a study published in the Jan. 15 issue of Spine.

Francis Lovecchio, from the Northwestern University Feinberg School of Medicine in Chicago, and colleagues analyzed data from the American College of Surgeon’s National Quality Improvement Database for all patients who underwent ACDF or anterior corpectomy and fusion procedures in 2011. The incidence of and factors affecting 30-day readmission were assessed.

The researchers found that the readmission rate after ACDF surgery was 2.5% nationwide. Readmitted patients were significantly older (58 vs. 53 years; P=0.003) and had higher rates of diabetes (28.8% vs. 13.9%; P=0.001) and hypertension (64.4% vs. 42.6%; P=0.001). The odds of operative complications were increased with preoperative factors, including age ≥65 years and preoperative stay >24 hours (odds ratios, 3.5 and 6.2, respectively). Outside of any effect on complications, the researchers found that hypertension may independently increase the likelihood of readmission (odds ratio, 1.8; 95% confidence interval, 1–3.4).

“The data in this study suggests that surgeons are already controlling readmission rates by limiting peri- and postoperative complications, but patients with a history of hypertension could have an increased likelihood of being readmitted despite avoiding a complication,” the authors write.
