Classification | SSI type |
---|---|
Superficial incisional SSI: | |
1 | Infection occurs within 30 days after the operation AND |
2 | Infection involves only skin or subcutaneous tissue of the incision AND |
3 | At least one of the following: |
A. Purulent drainage, with or without laboratory confirmation, from the superficial incision | |
B. Organisms isolated from an aseptically obtained culture of fluid or tissue from the superficial incision | |
C. At least one of the following signs or symptoms of infection: pain or tenderness, localized swelling, redness, or heat and superficial incision is deliberately opened by surgeon, unless incision is culture negative | |
D. Diagnosis of superficial incisional SSI by the surgeon or attending physician | |
Deep incisional SSI: | |
1 | Infection occurs within 30 days after the operation AND |
2 | Infection involves deep soft tissues (for example, fascial and muscle layers) of the incision AND |
3 | At least one of the following: |
A. Purulent drainage from the deep incision but not from the organ/space component of the surgical site | |
B. A deep incision spontaneously dehisces or is deliberately opened by a surgeon when the patient has at least one of the following signs or symptoms: fever (>38°C), localized pain, or tenderness, unless site is culture negative | |
C. An abscess or other evidence of infection involving the deep incision is found on direct examination, during reoperation, or by histopathologic or radiologic examination | |
D. Diagnosis of a deep incisional SSI by a surgeon or attending physician | |
Notes: (1) report infection that involves both superficial and deep incision sites as deep incisional SSI; (2) report an organ/space SSI that drains through the incision as a deep incisional SSI | |
Organ/space SSI: | |
1 | Infection occurs within 30 after the operation AND |
2 | Infection involves any part of the anatomy (for example, organs or spaces), other than the incision, which was opened or manipulated during an operation AND |
3 | At least one of the following: |
A. Purulent drainage from a drain that is placed through a stab wounda into the organ/space | |
B. Organisms isolated from an aseptically obtained culture of fluid or tissue in the organ/space | |
C. An abscess or other evidence of infection involving the organ/space that is found on direct examination, during reoperation, or by histopathologic or radiologic examination | |
D. Diagnosis of an organ/space SSI by a surgeon or attending physician |
