Introduction to the Centers for Disease Control and Prevention and Healthcare Infection Control Practices Advisory Committee Guideline for Prevention of Surgical Site Infection: Prosthetic Joint Arthroplasty Section

Peri-prosthetic joint infection (PJI) is a severe complication of total joint arthroplasty that appears to be increasing as more of these procedures are performed. Numerous risk factors for incisional (superficial and deep) and organ/space (e.g., PJI) surgical site infections (SSIs) have been identified. A better understanding and reversal of modifiable risk factors may lead to a reduction in the incidence of incisional SSI and PJI. The Centers for Disease Control and Prevention (CDC) and the Healthcare Infection Control Practices Advisory Committee (HICPAC) recently updated the national Guideline for Prevention of Surgical Site Infection. The updated guideline applies evidence-based methodology, presents recommendations for potential strategies to reduce the risk of SSI, and includes an arthroplasty-specific section. This article serves to introduce the guideline development process and to complement the Prosthetic Joint Arthroplasty section with background information on PJI-specific economic burden, epidemiology, pathogenesis and microbiology, and risk factor information.
