Study: Perioperative techniques reduced surgical site infection rates following THA

Reductions in total hip arthroplasty postoperative surgical site infection rates can be made through the use of several perioperative techniques, according to a recently presented study.
Jay R. Lieberman, MD, shared his findings at the Combined Open Meeting of the Hip Society and the American Association of Hip and Knee Surgeons, in San Francisco.
“There are a number of things we can do to try and reduce infections,” Lieberman said. “One is prophylactic antibiotics, another is skin preparations and then there is preoperative bacterial decolonization.”

Standard protocols for antibiotic prophylaxis should include cefazolin, Lieberman noted, adding it should be administered less than 1 hour prior to the procedure. Patients who have an allergy can be given vancomycin or clindamycin, although if vancomycin is going to be used it should be started earlier.
Further, he noted, prophylactic antibiotics should be discontinued within 24 hours of the end of a procedure.
For skin preparation, Lieberman spoke on preoperative showers, hair removal and antiseptic techniques to sterilize skin. With regard to chlorhexidine gluconate (CHG) preoperative wash, he noted studies of mixed quality have found mixed results as to its efficacy — but it is an area for further study.
“This is an area of controversy in orthopedics because there is not a lot of data, particularly related to total joint replacement, and the clean nature of our cases makes infection rare,” Lieberman said. “There have been some recent clinical trials to assess [CHG’s] efficacy, but again, they are not in orthopedic surgery.”
Up to 30% of infections are caused by Staphylococcus aureus, Lieberman noted. Since it is a virulent pathogen, he noted, there has been interest in eliminating nasal carriage preoperatively.
“I think the decolonization is becoming more popular, but cost-benefit analysis studies need to be performed,” Lieberman said. “More studies need to be performed to determine the efficacy of CHG showers, and what we really need is an in-office test that is cheap to make this work more easily for us.”
