The document discusses surgical site infection care bundles. It defines a surgical site infection as an infection related to a surgical procedure that occurs within 30 days of surgery or up to 90 days if an implant is involved. It then classifies SSIs as superficial incisional, deep incisional, or organ/space infections depending on the site and timing. The rest of the document outlines a care bundle with evidence-based practices to prevent SSIs, including proper hair removal and skin prep, tight glucose control, antibiotic prophylaxis timing, and wound care after surgery.
