A Meta-Analysis Examining the Effect of Perioperative Biologic Disease-Modifying Anti-Rheumatic Medications on Postoperative Wound Complications in Various Orthopedic Surgeries.

ABSTRACT

This meta-analysis was designed to compare the risk of postoperative wound complications in various orthopedic surgeries (OSs) affected by the perioperative use of biologic disease-modifying anti-rheumatic drugs (bDMARDs). The odds ratio (OR) and mean difference (MD), with 95% confidence intervals (CIs), were calculated using dichotomous or continuous random or fixed-effect models, based on the meta-analysis data. This study incorporated 14 investigations conducted between 2005 and 2023, encompassing a total population of 19,021 individuals undergoing diverse OSs. Participants who continued their bDMARDs exhibited a substantially higher incidence of postoperative surgical site infections (OR, 1.39; 95% CI, 1.12-1.72, p = 0.002) compared to those who withheld bDMARDs. However, the study did not find any statistically significant difference between the continuation or withholding of bDMARDs regarding delayed wound healing (OR, 2.02; 95% CI, 1.00-4.06, p = 0.05) or disease flares (OR, 0.59; 95% CI, 0.28-1.25, p = 0.17). The results show that patients who continued their bDMARDs had a notably higher incidence of postoperative surgical site infections. However, no significant differences were observed in delayed wound healing or disease flares when compared to those who withheld bDMARDs. It is important to acknowledge the limitations of this analysis, such as the relatively small number of participants and the limited number of studies available for certain comparisons, which may impact the validity of the findings.
