title: Intravenous piperacillin/tazobactam plus fluoroquinolone prophylaxis prior to prostate ultrasound biopsy reduces serious infectious complications and is cost effective.
abstract: Infectious complications related to prostate ultrasound and biopsy have increased in the past decade with the emergence of increasing fluoroquinolone bacterial resistance. We investigated the addition of intravenous (iv) piperacillin/tazobactam immediately prior to prostate ultrasound and biopsy with standard fluoroquinolone prophylaxis to determine if it would decrease the incidence of serious infectious complications after prostate ultrasound and biopsy. Group 1 patients were a historic control of 197 patients who underwent prostate ultrasound and biopsy with standard fluoroquinolone prophylaxis. Group 2 patients, 104 patients, received standard fluoroquinolone prophylaxis and the addition of a single dose of iv piperacillin/tazobactam 30 minutes prior to prostate ultrasound and biopsy. There were ten serious bacterial infectious complications in group 1 patients. No patients in group 2 developed serious bacterial infections after prostate ultrasound and biopsy. There was approximately a 5% incidence of serious bacterial infection in group 1 patients. Subgroup analysis revealed an almost 2.5 times increased risk of infection in diabetes patients undergoing prostate ultrasound and biopsy. There was a 10% risk of serious bacterial infection in diabetics compared with a 3.8% risk group 1 nondiabetes patients. The addition of a single dose of iv piperacillin/tazobactam along with standard fluoroquinolone prophylaxis substantially reduces the risk of serious bacterial infection after prostate ultrasound and biopsy (P < 0.02).
