The purpose of this study is to evaluate the prevalence of pre-surgical patients who are MRSA carriers. From an evidence-based practice perspective, findings from this study can be considered in the evaluation of the hospital SOP mandating pre-surgical MRSA screening requirements for patients with scheduled surgeries.

The central hypothesis to be addressed in this study is whether the MRSA colonization and subsequent post-operative infection are the equivalent in these populations.

Primary Outcome Measures:
  • The primary objective of this study is to compare the prevalence of MRSA colonization and its relationship to post-operative infection in patients who are currently pre-operatively MRSA screened per SOP to those who are not. [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • The secondary objective is to compare medical charges associated with diagnosis and treatment of post-operative infections for these groups using cost-effectiveness analysis. [ Time Frame: 30 days ]

Detailed Description:

Design and Methods: Subjects in this study of 975 pre-operative, scheduled surgical patients are in one of the three following groups:

  • Group 1 (N=325): Allocation sample of surgical patients required to be MRSA screened per hospital SOP (including patients having a positive MRSA history, orthopedic surgery, undergoing dialysis, or transfer from another hospital, nursing home, skilled nursing facility, or jail).
  • Group 2 (N=650): Randomized sample (1:1 ratio) of surgical patients not required to be MRSA screened per hospital SOP, to one of the following two groups:

    • 2a (N=325): MRSA screening; or
    • 2b (N=325): No MRSA screening. All subjects were followed for 30 days post-operatively to determine the incidence of post-operative infection. Treatment, diagnostic, and hospitalization data were collected for patients diagnosed with post-operative infection.
