Background Perioperative antibiotics reduce surgical site infections after hip and knee arthroplasty. Clindamycin is routinely used as a perioperative antibiotic in patients with beta-lactam allergy labels instead of first-line antibiotics like cefazolin. The purpose of this study is to assess the risk of adverse outcomes associated with the use of clindamycin to prevent surgical site infections (SSI) after total joint arthroplasty. Methods This retrospective review included adult patients labeled as allergic to penicillin or cephalosporin antibiotics, who underwent a primary total hip and/or knee arthroplasty between January 2020 through July 2021, and received perioperative antibiotics. The outcomes of SSI and Clostridioides difficile infection (CDI) within 90 days was compared between patients receiving perioperative clindamycin vs. non-clindamycin antibiotics. Results A total of 1,121 surgical procedures in 1,047 patients were included. The frequency of SSI for the cohort was 1.6% and CDI was 0.4%. SSI occurred more frequently in the clindamycin group than in the non-clindamycin group (4.3% vs 0.7%, p< .01). The average duration from surgery to SSI was 22.7 ± 11.6 days in the clindamycin group and 24.8 ± 11.1 days in the non-clindamycin group. The frequency of CDI occurrence was greater in the clindamycin group than the non-clindamycin group (1.1% vs. 0.1%, p=.05). The average duration from surgery to CDI was 32.6 + 26.6 days in the clindamycin group and 4.6 days in the non-clindamycin group. Multivariable logistic regression identified clindamycin-containing perioperative antibiotic regimens (odds ratio (OR) 5.5) and opioid use prior to surgery (OR 8.7) as risk factors for 90-day surgical site infection. Staphylococcus aureus was the cultured pathogen in 9 of the 17 SSIs. Conclusion This study found a significantly higher frequency of SSI and CDI when clindamycin-based regimens are used perioperatively for primary hip and knee arthroplasty. These results are likely related to decreased activity of clindamycin against Staphylococcus aureus and greater alterations of the microbiome in comparison to beta-lactams.
