NCT05701475

Brief Summary

Patients planned for shoulder surgery will be identified and contacted for participation. After informed consent is provided, patients will be randomised into one of three groups: pre-operative cutaneous disinfection with iodine (control group), pre-operative cutaneous and subcutaneous disinfection with iodine (double prevention), and pre-operative cutaneous and subcutaneous disinfection with iodine combined with a skin preparation protocol with benzoyl peroxide gel in the days prior to surgery (triple prevention). Bacterial cultures will be collected during surgery of the surgical field and tissue layers. Culture positivity for Cutibacterium Acnes will be compared between the groups as a primary outcome.
