Agrawal S, Ingrande J, Said ET, et al. - In this study, the correlations between preoperative smoking and 30-day postoperative outcomes were distinguished in patients undergoing total hip arthroplasty. Researchers applied R statistics to conduct a multivariable logistic regression analysis followed by a propensity score matching analysis to evaluate the relationship between preoperative smoking and postoperative outcomes. They included a final cohort of 67,897 patients who had undergone total hip arthroplasty for analysis. The multivariable regression analysis demonstrated a significant increase in pulmonary and infectious complications, as well as significantly longer hospital stays in our smoking population after controlling for potential confounding variables. An increase in infectious complications, as well as extended hospital stay, was observed when applying a propensity score matching analysis. The data serve updated information toward a growing mass of literature supporting smoking cessation before surgical operations, given the concerning prevalence of smoking in the United States.
