Abstract
Background:
While tobacco use is a well-known risk factor for adverse outcomes after carpal tunnel release (CTR), the impact of non-tobacco nicotine products remains unclear. This study evaluated complications in CTR patients with non-tobacco nicotine dependence (NTND) compared with tobacco users and controls.
Methods:
Patients who underwent CTR with ≥2-year follow-up were identified using a large national database. After 1:1 propensity score matching, patients with NTND (n = 6319) were matched to controls, tobacco users (n = 86 430) were matched to controls, and patients with NTND (n = 6325) were matched to tobacco users. Matching was based on age, gender, Charlson comorbidity index, and comorbidities. Outcomes including 90-day medical complications, infection, emergency department (ED) visits, readmissions, and 2-year revision rates were compared using multivariable logistic regression.
Results:
Compared with controls, patients with NTND demonstrated higher 90-day medical complication rates (2.4% vs 1.7%; odds ratio [OR], 1.35; 95% CI, 1.04-1.77) and ED visits (10.3% vs 8.1%; OR, 1.16; 95% CI, 1.02-1.32). Compared with tobacco users, patients with NTND had decreased ED visits (10.4% vs 14.2%; OR, 0.74; 95% CI, 0.66-0.83) and revision surgery (1.9% vs 2.5%; OR, 0.78; 95% CI, 0.62-0.99), with no significant differences in medical complications, infection, or readmissions.
Conclusions:
Non-tobacco nicotine dependence was associated with increased medical complications and ED visits compared with controls, but decreased ED visits and revision surgery compared with tobacco users. There were no significant differences in medical complications, infections, or readmissions between tobacco users and patients with NTND. These findings underscore the importance of screening for non-tobacco nicotine use during preoperative evaluations for CTR.
