| Type | Depth | Criteria |
|---|---|---|
| Superficial | Skin & subcutaneous | Within 30 days; purulent discharge, positive culture, or surgeon diagnosis |
| Deep Incisional | Fascia & muscle | Purulent discharge from deep incision; dehiscence; surgeon opens wound; fever + localised pain |
| Organ/Space | Organs or spaces | Drain placed through stab wound; positive culture from aspirate; imaging evidence |
- Affects 2–5% of surgical patients globally
- Leading cause of hospital readmission post-surgery
- Prolongs LOS by 7–11 days on average
- ~$10,000–$25,000 USD additional cost per SSI episode
- 3rd most common healthcare-associated infection (HAI) worldwide
- SSI mortality risk up to 3× higher in organ/space infections

| Organism | Frequency | Clinical Note |
|---|---|---|
| Staphylococcus aureus | Most common (#1) | Skin flora; nasal carriage 20–30%; golden pus, localised swelling |
| MRSA | High in GCC | Requires decolonisation + contact precautions; vancomycin/daptomycin |
| CoNS (S. epidermidis) | Common | Implant-related SSI; biofilm formation; often indolent presentation |
| E. coli / Klebsiella | Abdominal surgery | GI flora; often polymicrobial; bowel prep reduces but does not eliminate |
| Pseudomonas aeruginosa | ICU / burns | Environmental contamination; anti-pseudomonal coverage needed |
| Candida spp. | Immunocompromised | Diabetics, post-bone marrow transplant; fluconazole or echinocandin |
| Enterococcus | GI / urological | VRE increasingly reported; limited antibiotic options |
Each factor scores 1 point. Total = 0–3. Higher score = higher SSI risk.

- Standardised SSI definition (CDC/NHSN criteria)
- Prospective surveillance for 30 days post-procedure
- Procedure-specific SSI rates tracked and benchmarked
- Monthly reporting to hospital infection control committee
- Pre-op antibiotic prophylaxis compliance tracked (%)
- Bundle compliance audits (skin prep, glycaemia, normothermia)
- Root cause analysis for SSI outlier events
- Staff education and training annually documented
- Chlorhexidine gluconate (CHG) 4% shower/wash — night before AND morning of surgery
- Ensure patient rinses from neck down; avoid eyes and ears
- No rinse after CHG — allow to air dry for maximum residual activity
- Wipes (2% CHG) acceptable if shower not possible (immobile patients)
- Document CHG wash in pre-op nursing checklist
- Do NOT use bar soap after CHG wash — negates antimicrobial activity
- Screen all elective surgical patients for S. aureus nasal carriage pre-op
- MRSA-positive: Mupirocin 2% nasal ointment TDS × 5 days pre-op
- MRSA-positive: CHG 4% wash daily × 5 days (body decolonisation)
- Vancomycin added to prophylaxis for known MRSA carriers
- MSSA-positive in high-risk procedures: consider mupirocin + CHG protocol
- Document decolonisation completion in pre-anaesthesia chart
- Clippers ONLY — never use razors (micro-lacerations increase SSI risk ×2)
- Remove hair as close to surgery time as possible (ideally <2h pre-incision)
- Never shave the night before — increases bacterial colonisation risk
- If hair is not in surgical field — do NOT remove
- Use single-use clipper heads; disinfect reusable clippers between patients
- HbA1c <8.5% required for elective surgery (optimise pre-op if possible)
- Target peri-operative blood glucose 140–180 mg/dL
- Glucose >200 mg/dL on day of surgery — consider postponing elective cases
- Insulin infusion protocol for major surgery (cardiac, orthopaedic)
- Monitor glucose every 1–2h intra-op and for 48h post-op
- Coordinate with endocrinology for poorly controlled DM patients
| Procedure Type | First-line Agent | MRSA Carrier / Allergy | Re-dosing Interval |

- Malnutrition significantly impairs wound healing — assess all elective patients
- Use MUST score (Malnutrition Universal Screening Tool) pre-op
- Refer to dietitian if MUST ≥2 or BMI <18.5 kg/m²
- Pre-op carbohydrate loading (12.5% maltodextrin drink 400 mL) up to 2h pre-op
- Encourage protein intake ≥1.2 g/kg/day in weeks before surgery
- Zinc, Vitamin C and Vitamin A support wound healing — supplement if deficient
- Early enteral feeding post-op reduces SSI risk (gut barrier integrity)
- Smoking impairs tissue perfusion, collagen synthesis and immune function
- SSI risk is 2–3× higher in active smokers
- Cessation ≥4 weeks before surgery is ideal for meaningful reduction
- Even short-term cessation (≥2 weeks) reduces respiratory complications
- Nicotine replacement therapy is appropriate pre-operatively
- Document smoking status and cessation counselling in nursing notes
- Referral to smoking cessation clinic for elective procedures

Surgical hand scrub (antiseptic)
Chlorhexidine 4% or povidone-iodine: 3–5 min scrub to mid-forearm — all surfaces including subungual spaces
OR: Surgical hand rub (ABHR)
Alcohol-based hand rub 3-step technique: hands, forearms, then hands again — total ~2 min application time; allow to dry completely
Gowning
Sterile gown donned first; circulator ties back ties; gown changed if contaminated
Gloving
Closed gloving technique by scrub nurse; double-glove for high-risk procedures (orthopaedic, prolonged surgery); change outer glove if puncture suspected
- Establish sterile field immediately before use — never set up the night before
- Sterile field boundary must be visible and unambiguous at all times
- Non-scrubbed personnel remain ≥30 cm from sterile field
- Sterile items handed to scrub from above the table level
- Any item that falls below the sterile field table level is considered contaminated
- Draping: surgeon applies sterile surgical drapes in sequence — small to large
- Adhesive iodophor incise drapes (e.g. Ioban) for high-risk cases
- Opened items recorded on scrub count sheet
- No talking directly over the sterile field
Pre-warming (30 min before induction)
- Forced air warming (FAW) blanket applied in pre-op area
- Warmed IV fluids for major surgery (>500 mL)
- Target core temperature >36.0°C before induction
Intra-operative (anaesthetic nursing role)
- Continuous temperature monitoring — oesophageal probe or bladder
- FAW underbody blanket maintained throughout procedure
- Warmed irrigation fluids (>37°C) for abdominal and thoracic cases
- Document temperature every 15 minutes on anaesthetic chart
- Alert surgeon + anaesthetist if core temperature <36°C
- Count performed: initial (before procedure), before wound closure, and at skin closure
- Scrub nurse and circulator count together — each verbally confirming
- Any discrepancy requires: surgeon notification, field search, X-ray if unresolved
- Retained foreign body is a never event — counts documented in legal record
- Radiofrequency detection systems (SmartSponge) recommended for complex cases
- Needles counted by number — sharps bin placed where visible to scrub
- Copious warm saline irrigation reduces microbial load before closure
- Avoid cold irrigation — exacerbates IPH
- Dilute povidone-iodine (0.35%) irrigation considered for contaminated wounds
- Achieve meticulous haemostasis — haematoma is a culture medium for bacteria
- Eliminate dead space — obliterate with sutures or consider drain placement
- Diathermy use: minimum effective setting to prevent tissue necrosis
- Bipolar preferred near nerves and in neurosurgery/ophthalmic cases
| Closure Type | Indications | Nursing Action |
|---|---|---|
| Sutures (absorbable) | Deep layers, subcutaneous fat; contaminated wounds | Pass correct suture in sequence; record suture type on count sheet |
| Sutures (non-absorbable) | Skin — nylon, prolene for clean wounds | Document suture material and removal date in nursing notes |
| Staples | Scalp, trunk, extremity clean wounds; fast closure | Load stapler; staple remover available at 7–14 days; document count |
| Tissue glue (Dermabond) | Superficial, low-tension, dry wounds; paediatric | Keep field dry; apply three thin layers; do NOT use in moist wounds |
| Steri-strips | Support closure; small wounds; paediatric | Ensure skin dry; apply perpendicular to wound; overlap edges |
- First dressing applied in the sterile field by the scrub nurse before drape removal
- Use sterile technique throughout — gloves maintained until dressing secured
- Non-adherent primary contact layer (e.g. Mepore, Adaptic) applied first
- Absorbent secondary layer for wounds expected to exude (abdominal, orthopaedic)
- Secure with skin-friendly tape — avoid circumferential bandaging on limbs
- Label dressing with date and time; document in operative nursing notes
- NPWT (negative pressure wound therapy) applied in theatre for selected complex cases
Surgical incision, traumatic, pressure, burns. Primary closure, secondary intention, tertiary/delayed. Document at every dressing change.
Assess for erythema (beyond normal 2cm post-op margin), warmth, induration, oedema, maceration, dehiscence, tunnelling.
Inspect base: healthy granulation (red/pink), slough (yellow), necrosis (black/brown), exposed tendon/bone/implant. Escalate if implant visible.
Serous (clear, normal), serosanguineous (pink-tinged, normal early), haemosanguineous (red — blood), purulent (yellow/green/grey — infected). Quantify: scant/moderate/heavy.
Measure length × width in cm. For open wounds: also depth and any undermining. Serial measurements track healing progression. Use disposable measuring tape.
- Leave intact theatre dressing for 48 hours if no soaking, no fever, no swelling
- Epithelial resurfacing begins in 24–48h; disruption increases infection risk
- First dressing change is an assessment opportunity — use WOUND acronym
- Strict aseptic technique: sterile gloves, sterile dressing pack, ANTT principles
- Remove old dressing gently — moisten if adhered; avoid stripping fragile skin
- Clean wound with sterile normal saline (0.9% NaCl) — no scrubbing
- Document wound appearance, exudate, dimensions in nursing notes
- Photograph wound with patient consent for continuity of care
| Wound State | Recommended Dressing |
|---|---|
| Clean primary closure, dry | Non-adherent island dressing (Mepore, Primapore) |
| Lightly exuding | Foam (Mepilex, Allevyn) — 3-day change |
| Moderately to heavily exuding | Alginate (Kaltostat, Sorbsan) or Hydrofibre (Aquacel) |
| At-risk / colonised wound | Antimicrobial: iodine-cadexomer (Iodosorb) or silver (Aquacel Ag) |
| Sloughy wound | Hydrogel (IntraSite) for autolytic debridement |
| Necrotic wound | Hydrogel or surgical debridement — escalate to surgeon |
| Complex/high-risk/open | NPWT (VAC therapy) — see below |
Indications
- Open/complex surgical wounds (laparostomy, dehiscence)
- High-risk primary closure (obese, diabetic, contaminated wound)
- Wounds with significant dead space
- Post-debridement to promote granulation
- Sternal wounds post-cardiac surgery
Nursing Management
- Check seal integrity every shift — air leak triggers alarm
- Record canister volume every shift — alert if >50 mL/h output
- Standard pressure: -125 mmHg continuous; lower for fragile tissue
- Change foam dressing every 48–72h (can extend to 7 days for prophylactic iNPWT)
- Irrigating NPWT (NPWTi): instil normal saline every 1–4h per protocol
- Document canister changes, output character, wound appearance
- Closed suction drains (e.g. Redivac, Blake) preferred over open drains
- Record drain output: volume and character every shift
- Criteria for removal: output <30 mL/24h for ≥2 days
- Milking/stripping drains only if prescribed — can increase suction trauma
- Keep drain site clean and dry — treat as separate sterile wound
- Drains left >5 days significantly increase infection risk — advocate for timely removal
- Biliary/urological drains: specialised removal protocols — surgical team decision
- Teach wound care in patient's primary language — translation services in GCC
- Demonstrate dressing change using teach-back method before discharge
- Provide written discharge instructions on wound care, bathing, showering
- When to seek immediate medical attention: fever >38°C, increasing pain, redness, pus
- Bathing: shower allowed when wound dry and closed (usually 48h); no soaking baths
- Diet: high-protein foods post-discharge to support healing
- Activity restrictions specific to procedure (e.g. no lifting, driving)
- Follow-up appointment — wound check and suture/staple removal date
| Sign | Assessment | Note |
|---|---|---|
| Rubor (Redness) | Erythema extending >2 cm from wound edge | Normal erythema <2 cm for first 48h; beyond that is abnormal |
| Calor (Warmth) | Periwound area warm to touch compared to contralateral site | Always compare bilaterally |
| Tumor (Swelling) | Induration, oedema, fluctuance (indicates collection) | Fluctuance suggests abscess — do not probe; escalate to surgeon |
| Dolor (Pain) | Pain disproportionate to operative day or re-escalating after initial improvement | Pain should trend DOWN after day 3; any re-escalation is a red flag |
| Purulent discharge | Yellow, green, grey or foul-smelling exudate from wound or drain | Sanguineous discharge on day 1–2 is normal; purulence is never normal |
| Systemic fever | Temperature >38.5°C after day 2 (not explained by another source) | Rule out atelectasis (day 1–2), UTI, line infection before attributing to SSI |
1. Prepare the wound
Clean wound with sterile normal saline first — remove surface debris and exudate
2. Select swab site
Target the most viable, granulating tissue — not surface slough, pus, or necrosis
3. Rotating pressure technique
Press swab firmly on 1 cm² area; rotate 360° while moving across the area in a zigzag for 5 seconds — applies sufficient pressure to sample deeper tissue fluid
4. Process immediately
Place in transport medium; deliver to microbiology within 2h; note: antibiotic patient — document current antibiotics on request form
5. Document and communicate
Record swab site, time, clinical findings in nursing notes; inform medical team of pending result
Isolation & Contact Precautions
- Single room with en-suite bathroom if possible
- Contact precautions: gloves and apron/gown for all patient contact
- Dedicated equipment (stethoscope, BP cuff, thermometer) for this patient
- Door signage per hospital MRSA policy
- Visitors educated on hand hygiene and contact precautions
- Notify infection control nurse immediately
Treatment & Decolonisation
- Vancomycin IV (target trough 15–20 µg/mL) or daptomycin if renal impairment
- Continue CHG body wash daily and mupirocin nasal ointment TDS
- Wound dressing: antimicrobial (silver or iodine-based)
- Repeat MRSA swabs post-treatment (nose, wound, axilla, groin)
- 3 consecutive negative screens required before clearing isolation
- Antibiotic duration: minimum 2 weeks for deep SSI; longer for implant infection
- Superficial dehiscence: cleanse, apply secondary wound closure strips or foam dressing
- Deep dehiscence: cover wound with moist sterile dressing, call surgical team urgently
- Evisceration (bowel protrudes): cover with moist sterile towel, keep supine, emergency OR
- Do NOT attempt to push eviscerated bowel back — risk of further injury
- IV access, fluid resuscitation, NBM status, anaesthetic team notification
- Document time of discovery, appearance, any precipitating factor (coughing, vomiting)
- Consider NPWT for bridging management pending return to theatre
- Suspect when: fever persists beyond day 5, wound pain worsens, no superficial source found
- Blood cultures × 2 sets before starting antibiotics (if clinically stable)
- Imaging: CT scan with IV contrast is the gold standard for intra-abdominal collections
- Ultrasound: bedside tool for superficial or pelvic collections
- Radiological drainage (IR-guided) preferred over open drainage when feasible
- Return to theatre indications: generalised peritonitis, failed IR drainage, anastomotic leak
- Nursing: strict fluid balance, sepsis bundle, escalation to critical care if organ dysfunction
| Severity | Empirical Regimen | Duration |
|---|---|---|
| Superficial SSI — mild | Flucloxacillin 500 mg PO QDS or co-amoxiclav 625 mg TDS | 5–7 days |
| Superficial SSI — MRSA suspected | Trimethoprim-sulfamethoxazole or doxycycline (MRSA-sensitive strains) | 7–10 days |
| Deep SSI — moderate | Cefazolin IV ± metronidazole | 10–14 days |
| Deep/Organ SSI — severe | Piperacillin-tazobactam ± vancomycin (MRSA cover) | 14–28 days (source control dependent) |
| Implant-related SSI | Vancomycin IV + rifampicin (biofilm penetration); ID team input essential | ≥6 weeks for implant retention |
- Screen all GCC surgical patients for diabetes — undiagnosed DM is common
- Peri-operative glucose monitoring: every 1–2h for known diabetics
- Insulin-sliding scale or infusion protocol for all major surgery
- Diabetic foot surgery: highest SSI risk group in GCC — multidisciplinary wound teams
- HbA1c optimisation: refer to endocrinology 4–8 weeks before elective surgery
- Post-discharge: ensure patient has glucometer and knows target range for wound healing
- Community health nurses: vital for post-discharge glucose monitoring in GCC home settings
- Use higher cefazolin dose: 3g IV for patients >120 kg
- Apply incisional NPWT prophylactically for BMI >40 + orthopaedic/abdominal surgery
- Skin fold moisture management pre-op: CHG wipes under skin folds
- Bariatric-specific theatre positioning: appropriate table and padding
- Subcutaneous drain placement for deep adipose tissue closure
- Extended prophylaxis duration not recommended — increases resistance risk
- MRSA rates vary widely: 20–40% of S. aureus isolates in some GCC hospitals
- Community-acquired MRSA (CA-MRSA) strains circulating in GCC — different from HA-MRSA
- Universal pre-op MRSA screening recommended for elective surgical patients
- Healthcare worker MRSA screening important — carrier nurses transmit to wounds
- Vancomycin MIC creep documented in GCC ICUs — daptomycin may be needed
- Infection control must review SSI microbiological data monthly for trends
- Antimicrobial stewardship programmes (ASP) now mandated in JCI-accredited GCC hospitals
- Tap water quality in GCC is generally good — clean water for wound irrigation at home
- Boiled water (cooled) or bottled water acceptable for wound irrigation if prescribed
- Humidity: some GCC areas have high humidity — increases wound maceration risk
- Patient preference: strong preference for hospital-based wound care over home care
- Outpatient wound clinics in GCC hospitals are heavily utilised — reduce SSI readmissions
- Home care nursing services available through MOH and private providers — refer when appropriate
- Educate patients: sterile-packaged saline for home wound cleaning — widely available in GCC pharmacies
Fasting Risks During Recovery
- Dehydration impairs tissue perfusion and wound oxygenation
- Reduced caloric intake slows collagen synthesis and epithelialisation
- Hyperglycaemia risk at Iftar (large rapid meal) then hypoglycaemia at Suhoor
- Medication timing disruption (oral antibiotics, anticoagulants)
Nursing Approach
- Consult with Islamic scholar or hospital chaplain if patient has doubts about fasting during illness (Islam permits breaking fast during illness)
- Encourage adequate oral hydration during non-fasting hours
- Adjust antibiotic and glucose monitoring schedule to Iftar/Suhoor times
- Emphasise high-protein Iftar meals to support wound healing
- Close monitoring for wound infection during Ramadan recovery period
JCI SSI Bundle Metrics (IPSG 5)
- Prophylactic antibiotic within 60 min of incision: target >95%
- Correct antibiotic selection per hospital formulary: target 100%
- Antibiotic discontinuation within 24h post-op: target >90%
- Pre-op blood glucose control in DM patients: documented
- Clippers used (not razors) documented: target 100%
- SSI rates by procedure type: quarterly reporting to quality committee
Antimicrobial Stewardship Nursing Role
- ASP is growing priority across GCC — antibiotic resistance accelerating
- Nurse advocates for IV-to-oral switch when patient clinically improving
- Remind prescribers: prophylaxis discontinuation at 24h — prolonged courses increase resistance
- Flag unexplained antibiotic continuations to pharmacist and ASP team
- Document culture results and communicate to prescriber promptly (de-escalation)
- Report antibiotic-resistant organisms to infection control within 24h
