Abstract
Objective: To investigate the prevalence and the risk factors of surgical-site infection (SSI) and delayed wound healing (DWH) in patients with rheumatoid arthritis (RA) underwent orthopedic surgery.
Methods: We reviewed the records of 1036 elective orthopedic procedures undertaken in RA patients. Risk factors for SSI and DWH were assessed by logistic regression analysis using age, body mass index, disease duration, pre-operative laboratory data, surgical procedure, corticosteroid use, co-morbidity, and use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and biological DMARDs (bDMARDs) as variables.
Results: SSI and DWH were identified in 19 cases and 15 cases, respectively. One case of SSI and three cases of DWH were recorded among 196 procedures in patients using bDMARDs. Foot and ankle surgery was associated with an increased risk of SSI (odds ratio (OR), 3.167; 95% confidence interval (CI), 1.256–7.986; p = 0.015). Total knee arthroplasty (TKA; OR, 4.044; 95% CI, 1.436–11.389; p = 0.008) and disease duration (OR, 1.004; 95% CI, 1.000–1.007; p = 0.029) were associated with an increased risk of DWH.
Conclusions: Our results indicated foot and ankle surgery, and TKA and disease duration as risk factors for SSI and DWH, respectively. bDMARDs was not associated with an increased risk of SSI and DWH.
