The impact of smoking and smoking cessation interventions on outcomes following single-level anterior cervical discectomy and fusion procedures

While several studies explore the impact of smoking tobacco on spinal fusion outcomes, there is a paucity of literature on the influence of modern smoking cessation therapies on such outcomes in patients undergoing anterior cervical discectomy and fusion (ACDF).Our study explores the outcomes of single-level ACDF surgery in nonsmokers, active smokers, and smokers undergoing cessation therapy.MARINER30, an all-payer claims database, was utilized to identify patients undergoing single-level ACDF between 2010 and 2019. The primary outcomes were the rates of composite surgical complications, dysphagia, hematoma, symptomatic pseudarthrosis, instrumentation removal, need for revision surgery, and all-cause readmission rates within 30 and 90-days.The matched population consisted of 5769 patients undergoing single-level ACDF with 1923 (33.33%) in each of the following groups: (1) nonsmokers; (2) active smokers; and (3) patients undergoing smoking cessation therapy. Nonsmokers had significantly lower rates of composite surgical complications (3.74% vs 13.05% vs 15.08%), revision surgery (4.06% vs 20.07% vs 22.88%), instrumentation removal (0.83% vs. 2.08% vs. 2.76%), and dysphagia (0.36% vs 0.99% vs 0.62%) when compared to patients in the active smoking and smoking cessation groups, respectively.Patients using smoking cessation therapy were more likely to develop postoperative dysphagia and undergo revision surgery when compared to their actively smoking counterparts. While surgeons routinely recommend smoking cessation prior to surgery, the effects of smoking cessation therapies on surgical outcomes are not well characterized.
