Abstract: AIMS: To determine the antiseptic efficacy on bacterial colony counts of a 5- vs 10-minute surgical site scrub in urologic surgery. METHODS: A prospective cohort study was conducted in 101 patients presenting for elective urological procedures. Patients were randomized to a 5- or 10-minute groin scrub with Betadine (povidone-iodine). Skin swabs were taken immediately after skin clipping and following routine painting with Betadine. A third swab was taken after the betadine skin scrub. Bacterial colony counts were reported as a number of colony-forming units (CFUs). The primary outcome measure was a quantitative comparison of CFUs in the two arms. RESULTS: Fifty-three patients were randomized to a 5-minute scrub and 48 to a 10-minute scrub. After Betadine painting, CFUs were present in 38% of patients in the 5-minute group (mean, 33.5 CFU) and in 27% of the 10-minute group (mean, 45.4 CFU). Following the surgical scrub, only 7.5% of the 5-minute group and 8.3% of the 10-minute group had a measurable CFU count of greater than or equal to 1, and colony counts were low in both groups (5- minute group: mean, 1.5 CFU; 10-minute group: mean, 2.0 CFU). There was no significant difference in CFUs following a 5- or 10-minute scrub (P = 0.28). CONCLUSIONS: The addition of a surgical skin scrub leads to a fourfold reduction in the skin CFU count compared with Betadine painting. However, there is no difference between the antibacterial effects of a 5- and 10-minute scrub. A 5-minute scrub may be sufficient in urologic prosthetic surgery.
