Background: Cigarette smoking increases the risk of peripheral artery disease and complications after endovascular and surgical intervention treatment. The current study investigates the effect of cigarette smoking on procedural cost of lower extremity (LE) endovascular intervention.
Methods: This study analyzed data from 2,353 procedures extracted from multicenter Excellence in Peripheral Artery Disease (XLPAD) registry collected between January 2005 and October 2015, which constitute 1,907 patients. The procedural cost distribution was right skewed with bi modalities (Figure 1.A), thus quantile regression models were used for cost estimation at quantiles of 10%, 25, 50, 75, and 90%. The models were adjusted for age, sex, race, comorbidities, lesion characteristics, and anatomic location of lesion at baseline.
Results: Smoking cessation pre intervention was positively associated with baseline concomitant comorbidities. Current smokers were at a more advanced vessel disease stage in lesion length, heavy calcification, and chronic total occlusions than never smokers. The marginal cost increases significantly in treating lifetime smokers compared to never smokers at 75% and higher quantiles (Figure 1.B). There was no marginal cost difference between current and past smokers at any quantile level (Figure 1.C).
Conclusions: Lifetime smoking increased procedural cost at 75% and higher quantiles, however smoking cessation did not reduce procedural cost of LE endovascular intervention.
