Association of Pre-Operative Full-Body Surgical Preparation with Reduced Incidence of Surgical Site Infection at a Large, Urban Safety-Net Medical Center.

Background: Surgical site infections (SSIs) continue to represent a substantial source of morbidity, mortality, and healthcare costs. The purpose of this study was to determine the effect of implementing a protocol using home pre-operative surgical preparation on the SSI rate at a large, urban safety-net medical center. Patients and Methods: From July through December 2020, Nose-to-Toes® (N2T; Sage Products-Stryker Corporation, Cary, IL) full-body preparation was applied by patients at home on the morning of scheduled surgical procedures. This study was a single-institution, retrospective observational analysis to determine the rates of SSI ≤30 days after an operation. Patients having skin preparation during 2020 (post-N2T) were compared with patients having the same operation during 2019 without having skin preparation (pre-N2T). Results: For gynecology, 10 (7.4%) of 135 pre-N2T and three (2.2%) of 135 post-N2T patients had SSIs. For surgical and gynecologic oncology, 13 (15.1%) of 86 pre-N2T and four (4.7%) of 86 post-N2T patients had SSIs. For orthopedics, four (4.3%) of 94 pre-N2T and zerp of 94 post-N2T patients had SSIs. Overall, 27 (8.6%) of 315 pre-N2T and seven (2.2%) of 315 post-N2T patients had SSIs (p = 0.0004). Conclusions: The implementation of pre-operative full-body preparation was associated with a substantial reduction in the incidence of SSI.
