Introduction :
Staphylococcus Aureus (SA) is the common microorganism that is commonly found on the skin and in the nostrils of people. Patients colonized with Staphylococcus aureus who are planning to undergo total hip or total knee operation may be at greater risk for acquiring a surgical site infection (SSI). Surgical site infections result in prolonged hospital stays, readmissions and increased mortality rates. The Institute for Healthcare Improvement (2012) had recommended that screening patients for staphylococcus aureus and decolonization of SA carriers prior surgery to prevent surgical site infection in patients undergoing hip and knee operation. A multi-departmental collaborative program was carried out by Infection Control Team (ICT) & Department of Microbiology, Specialist Out-Patient Department of Orthopaedic and Traumatology (SOPD / O&T), Adults wards of Department of Orthopaedic and Traumatology (O&T), Day Surgery centre of Department of Anaesthesia & Intensive Care. Patients undergoing elective Total Hip Replacement (THR) and Total Knee Replacement (TKR) were identified, selected patients were recruited for pre-operative MSSA / MRSA screening & decolonization program in PWH.
Objectives :
To implement pre-operative screening & decolonization for patient undergo elective total hip / knee replacement in October 2018 To identify the number and rate of Staphylococcus aureus colonization (MSSA / MRSA) in the pre-operative screening program To reduce the rate of Staphylococcus aureus surgical site infection in elective total hip and knee replacement operation
Methodology :
A prospective review of patient undergone screening & decolonization was performed. Outcome measures include the effectiveness of collaboration program, the efficacy of screening & decolonization protocol and the rate of Staphylococcus surgical site infection.
Result & Outcome :
There were a total of 32 patients screened since October 2018, mean age was 70.9 (47-89 years). Male to Female ratio was 7: 25. The prevalence of MSSA & MRSA colonization rate was found to be 31% & 0%. There was no staphylococcus SSI reported in elective total hip & knee operation. The initial results of the multi-departmental collaborative program were promising. However, due to the limitation of the case number collected, more data was needed to evaluate the long-term effectiveness of the program. ICT will continue to monitor the result of this program and report the finding to relevant stakeholders in the future.
