Groups and cohorts

  • control

    Patients with growth of S. aureus from sterile site cultures between Sept 15, 2012 - Dec 31, 2012. No rapid testing was performed, and standard bacterial culture and susceptibility testing was done.

  • intervention

    Patients with growth of S. aureus from sterile site cultures between Sept 15, 2013 - Dec 31, 2013. Rapid PBP2a testing was performed along with pharmacist notification of service if modification to therapy needed based on rapid test results.

What researchers measure

Primary outcomes

  1. Time (hours) to optimal antimicrobial therapy for patients with MSSA and MRSA infections in the pre-intervention and post-intervention periods

    Time frame: within first 7 days of culture result

Secondary outcomes

  1. Time (in hours) to identification of MRSA.

    Time frame: within first 3 days of culture result

  2. Vancomycin days of therapy following S. aureus culture result

    Time frame: during the 2 weeks following culture result

Other outcomes

  1. Proportion of patients with MSSA infection who are switched from an MRSA-active drug to an MSSA-active drug .

    Time frame: within 48 hours of Gram-stain result

  2. Duration of bacteremia in patients with MSSA or MRSA bloodstream infections

    Time frame: within first 30 days of culture result

  3. Time to contact isolation in patients with MRSA infections

    Time frame: within first 7 days of culture result

  4. Length of hospitalization

    Time frame: from time of culture result to hospital discharge, an expected average duration of 4 weeks

  5. Total healthcare costs (broken down by bed, laboratory, and pharmacy costs).

    participants will be followed for the duration of hospital stay following positive culture result, an expected average of 4 weeks.

    Time frame: from time of culture result to time of hospital discharge, an expected average duration of 4 weeks

  6. Proportion of patients where a electronic (P-care) rule flagged for discordant therapy for the PBP2a result

    Time frame: within first 3 days after culture result

  7. Proportion of patients where the pharmacist contacted the service to modify therapy

    Time frame: wihtin first 7 days after culture result
