Patients were interviewed in person baseline and by phone at 2 weeks, 3 months, and 6 months using a standardized questionnaire. The baseline survey, based on a previously developed instrument used for an epidemiologic investigation of MRSA asked about MRSA risk factors and health-related quality of life. Follow up surveys asked about adverse drug effects, especially gastrointestinal and dermatologic side effects (2 week visit only) and incident skin and MRSA infections.
