The use of home preoperative chlorhexidine wash has been used in various surgical fields for the prevention of perioperative infections. However, it's use in shoulder surgery has not been published up to this point. The shoulder has a unique microbial flora due to the prevalence of Propionibacterium acnes, a bacteria implicated in surgical site infections after shoulder surgery. This study is designed to examine the efficacy of using a preoperative Sage 2% chlorhexidine cloth in reducing bacterial load in the pre-operative area as well as in reducing post-operative surgical site infections after shoulder surgery. This study will compare the rate of post-operative infections and also the rate of positive skin cultures. The skin cultures will be obtained in the preoperative area from subjects who used the Sage 2% Chlorhexidine cloth protocol pre-operatively (n=50) versus those who used only soap and water (n=50).
