Prepping for Prevention: An Intervention to Optimize Skin Antisepsis and Peri-Operative Antibiotic Prophylaxis

The U.S. Centers for Disease Control and Prevention recommend bathing prior to surgery, surgical skin antisepsis, peri-operative antibiotic administration, normothermia throughout the procedure, serum glucose concentration <200 mg/dL throughout the procedure, and hyperoxygenation in the immediate post-operative period to prevent surgical site infection (SSI). We developed interventions to standardize skin antisepsis and peri-operative antibiotic administration at our institution. This is a cross-sectional evaluation of surgical skin antisepsis and antibiotic administration before and after a series of interventions designed to standardize the processes. One hundred twenty-four surgical skin antisepsis opportunities were observed; significant improvement was seen in hand hygiene prior to performing skin antisepsis (compliance changing from 1% to 48%; p < 0.001), sleeves being worn during skin antisepsis (1% versus 67%; p < 0.001), use of the correct cleansing time (47% versus 85%; p < 0.001), allowance for adequate drying time (67% versus 87%; p = 0.02), and use of a cleansing motion from the incision to the periphery (78% versus 95%; p = 0.004). Pre-operative antibiotic order placement, correct antibiotic selection, and optimal antibiotic dose were evaluated in 466 surgical procedures. Significant improvement was seen in both peri-operative order placement (59% versus 70%; p = 0.02) and correct antibiotic selection (52% versus 95%; p < 0.001). An intervention to standardize skin antisepsis and to encourage early ordering of peri-operative antibiotics was successful.
