CA-MRSA Infections - Management by Primary Care Clinicians of Patients Suspected of Having Community-Acquired, Methicillin-Resistant Staphylococcus Aureus Infections

Study Description and Methods

Conduct electronic chart audits followed by more in-depth manual audits to increase our understanding of CA-MRSA diagnosis, treatments, and documentation. This will assist in the development of real-world, sustainable strategies consistent with the CDC guidelines that busy primary care practices can adopt.

Specific Aims and Objectives

  1. Describe the baseline incidence and clinical practice for SSTIs in three large health systems, two private health systems, and a large integrated urban community health center.
  2. Design two intervention strategies and associated outcome measures consistent with the CA-MRSA CDC guidelines.
  3. Conduct a clinical trial evaluating the effect of the intervention strategies on the outcomes in primary care clinics within two health care systems.


This project was conducted from September 1, 2008, through March 31, 2010.


This study is complete.

Key Findings and Publications

Findings indicate that the intervention used in this study resulted in increased use of antibiotics, including antibiotics that typically cover MRSA strains, but did not demonstrate increased rates of recommended drainage procedures.
