| Sumario: | To pursue an irreducible minimum overall surgical site infection (SSI) rate, a 32-bed surgical hospital employed an outside consultant and performed sterile processing and surgery internal audits: No obvious improvements were identified. A 10-year review determined that 70% of SSI's were spine procedure patients. After a nasal decolonization product literature review, an intervention was implemented. The purpose of this study was to assess if the intervention impacted spine SSI rates. A 36-month implementation science study was conducted. The 18-month intervention was the immediate preoperative application of a manufactured presaturated 10% povidone-iodine nasal decolonization product in spine surgery patients, with monthly product application documentation surveillance feedback to the preoperative staff. Chi-square test was used to determine the difference in types of spine SSI surgery rates pre and post intervention. Overall spine SSI decreased 35.7% (P =.04) with a 58.7% reduction in superficial incisional SSI (P =.02). The 16.1% decline in deep incisional SSI was not significant (P =.29). Within this hospital, conducting 7,576 surgical spine procedures over 36 months, with the immediate preoperative application of a presaturated 10% povidone-iodine nasal decolonization product, the only intervention in SSI prevention protocol, produced a statistically significant decrease in spine patient SSI rate percent. • Spine surgery surgical site infection with 10% povidone-iodine nasal decolonization. • Implementation science in spine surgery and surgical site infection rate impact. • Interventional epidemiology changes one thing with spine surgery infection outcome.
