Surgical Site Infection (SSI)
• 2nd most common health care associated infection
• Accounts for 14-16% of hospital-acquired infections
• Increase patients’ morbidity, mortality, length of stay and cost of healthcare institutions
• Increase LOS by an average of 7.5 days

Classification of SSI
• Superficial incisional SSIs (skin & subcutaneous tissue)
• Deep incisional SSIs (deep soft tissuemuscule & fascia)
• Organ/space SSIs (involve any part of the anatomy)

Most common organisms of SSI
• Staphylococcus aureus (20%)
• Coagulase negative staphylococcus (14%)
• Enterococcus (12%)

Pre Op
• Schedule case - start from clinic (e.g. JRT)
• Emergency admission
- start from admission
- even better start from site of injury
![Page 7: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/7.jpg)
Contributing factors to infection
• Environmental factor
Clean environment
• MOI (mechanism of injury)
Mechanical injury (RTA)
Thermal injury (Burns & Scald)
![Page 8: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/8.jpg)
Contributing factors to infection
• Patient factors
major contribution factor e.g. knowledge, ability, hygiene, obesity, age, nutritional status, smoking
• Education is very important - education class
• Skin cleansing product, clean pajamas, post op bed preparation

Contributing factors to infection
• Practices
• Guideline & Protocol should be clear and well established
![Page 10: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/10.jpg)
Pre-op preparation of patient
• Identify and treat all infections remote to surgical site whenever possible
• Screen of hyperglycaemia: Patients with a blood sugar > 300 mg/dL during or within 48 hours of surgery had more than 3X the likelihood of a wound infection
![Page 11: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/11.jpg)
Pre-op preparation of patient
• Minimize the pre-operatively LOS: complete pre-op assessments and correct underlying condition before admitted for surgery
• Educate about cessation of smoking: stop at least 30 days before OT
• Maintain normothermia
![Page 12: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/12.jpg)
Pre-op preparation of patient
• Do not remove hair preoperatively unless
it will interfere with the operation
• Remove hair immediately before the
operation, electric clippers preferred, no
shaving
![Page 13: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/13.jpg)
Pre-op preparation of patient
• Education on bath at least night before OT
• Use hibitane for bathing at least the night
before surgery
• Bowel preparation if needed
![Page 14: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/14.jpg)
Pre-op preparation of patient
• No antiseptic skin preparation in clinical
areas
• Administer prophylactic antibiotic 30min
before surgical incision (relatively narrow
spectrum antibiotics, e.g. Cephazolin)
![Page 15: Prevention of Surgical Site Infection - From pre-operative ...aado.org/file/nurse_conf2013_pssi-ws_handout/Marble-Prevention of... · Infection - From pre-operative preparation to](https://reader031.fdocuments.net/reader031/viewer/2022020315/5af9b85e7f8b9a5f588e6f9b/html5/thumbnails/15.jpg)
Surgical clipper
• No hair removal is best
• Use of razors to remove hair has been
identified as a primary reason for
increased surgical site infection
• Clipping is preferred over shaving as
clipping causes less epithelial damage

Surgical clippers
Infection rate (%)
Not shaved or clipped 0.9%
Shaved with a razor 2.5%
Hair is clipped 1.7%
Shaved with an
electrical razor
1.4%

Centers for Disease Control and Prevention, “Guideline for Prevention of Surgical Site Infections,” Infection Control and Hospital Epidemiology, Vol 20, No 4, April 1999
Preoperative Bathing Recommended Practice
Require patients to shower or bathe with an antiseptic agent at least the night before the operative day (Category IB) “Chlorhexidine gluconate-containing products require several applications to attain maximum antimicrobial benefit, so repeated antiseptic showers are usually indicated. Even though preoperative showers reduce the skin’s microbial colony counts, they have not definitively been shown to reduce SSI rates”

Post op Mx
• Keep dressing intact for 24-48 hours post-op
• Change dressing with normal saline if soaked
• Hand hygiene before and after perform dressing
• Use aseptic technique to perform dressing
• Use disposable product (e.g. mask, gloves, gown & drapes) to prevent cross-infection

Post op Mx
• Observe for S/S of wound infection: pain or tenderness, localized swelling, redness or heat, fever
• Administer antibiotics as prescribed
• Teach the patients and their carers to report for any wound problem occur

Conclusion
Just simple and basic nursing care is
enough
Prevention is base on nursing care and
attitude
(good practice)
