Prospective Randomized Trial of Bactrim on 7 Day Outcome in Patients With Uncomplicated Abscesses

March 1, 2010 updated by: 59th Medical Wing

Randomized Placebo-Controlled Trial of Bactrim on 7 Day Outcome in Emergency Department Patients With Uncomplicated Abscesses at Risk for Community Acquired Methicillin Resistant Staph Aureus

Patients will be enrolled in a multi-center study to prospectively evaluate outcome after treatment for an uncomplicated skin abscess. All patients will receive incision and drainage and wound cultures. Patients will then be randomized to 1) placebo two tablets PO BID X 7 days or 2) bactrim DS (800/160) two tablets PO BID x 7 days. Patients will then return to the emergency department ED) at 48 hours and 7 for wound repacking and evaluation. The primary outcome is treatment failure rates at 7 days after incision and drainage. Patients who are clinically worsening or not improving after 48 hours will then be treated with additional antibiotics or admission if needed. Data will be analyzed both by initial randomization and intention to treat.
