Effectiveness of Screening and Decolonization of S. Aureus to Prevent S. Aureus Surgical Site Infections in Surgery Outpatients

Recruiting

• Conditions: Surgical Site Infections; Staphylococcus Aureus Colonization; Healthcare Associated Infections

• Registration Number: NCT06378359
• Lead Sponsor: University of Minnesota

Brief Summary

The purpose of the study is to determine the effectiveness, safety, and health-care utilization and costs of a preoperative Staphylococcus aureus (SA) screening and decolonization bundle, (5 days of nasal mupirocin ointment, chlorhexidine gluconate (CHG) body wash, and CHG mouth rinse), in eradicating SA carriage compared to other SA decolonization approaches. The study will conduct a single center pilot trial to compare efficacy of different SA decolonization approaches in pre-surgical patients, in eradicating SA carriage, after obtaining informed consent.

The study will compare four different approaches, Arm 1) screen for SA carriage and using the three-drug decolonization bundle for 5 days among patients with SA colonization, non SA carriers in this arm will get two pre-op showers with CHG soap, Arm 2) all participants receive the three drug decolonization bundle, Arm 3) all receive pre-op nasal povidone iodine the day of surgery plus two pre-op showers with CHG soap, and Arm 4) all receive nasal alcohol gel the day of surgery plus two pre op showers with CHG soap.

The primary efficacy outcome will be eradication of SA colonization at all 5 body sites. Secondary outcomes will be SA surgical site infections (SSIs), all SSIs, and SA healthcare associated infections (HAIs). The study will also compare eradication of SA from each of the 5 body sites as a secondary outcome.
