What are the different types of surgical site infections (SSIs) described in the chapter?

The chapter describes three types of surgical site infections: superficial incisional SSI, deep incisional SSI, and organ or space SSI.

Surgical site infections (SSIs) are categorized into three types based on their location and depth. Superficial incisional SSIs occur at the skin level where the surgical incision was made. Deep incisional SSIs affect the tissues beneath the incision, including muscle and surrounding tissues. Organ or space SSIs occur in any area of the body other than the skin, muscle, and surrounding tissue involved in the surgery, such as a body organ or a space between organs.
