Summary
A preadmission chlorhexidine skin preparation protocol significantly reduced surgical site infections in total knee arthroplasty patients. This method offers a promising strategy for preventing infections in orthopedic surgery.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Prevention
Background:
- Surgical site infections (SSIs) are a significant complication following total knee arthroplasty (TKA).
- Standard in-hospital perioperative skin preparation may not be sufficient to prevent SSIs.
Purpose of the Study:
- To evaluate the efficacy of a preadmission chlorhexidine skin preparation protocol in reducing SSIs after TKA.
- To compare SSI incidence between patients using chlorhexidine cloths and those receiving standard care.
Main Methods:
- Retrospective review of TKA patient records from 2007-2010.
- Comparison of deep incisional and periprosthetic infection rates between a chlorhexidine group (478 patients) and a standard care group (1,735 patients).
- Chlorhexidine protocol involved pre-operative use of chlorhexidine gluconate-impregnated cloths.
Main Results:
- The incidence of SSIs was significantly lower in the chlorhexidine group (0.6%) compared to the standard care group (2.2%).
- This represents a substantial reduction in infection rates for TKA patients.
Conclusions:
- Preadmission use of chlorhexidine skin preparation is an effective strategy for preventing SSIs in TKA.
- Implementing this protocol can improve patient outcomes and reduce healthcare-associated infections.

01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
