Infection Control
in the ICU

Why ICU Infection Control is Critical for NABH

Hospital-acquired infections (HAIs) in the ICU — CLABSI, CAUTI, VAP, and SSI — are tracked as mandatory KPIs under NABH 6th Edition standards. The ICU is the highest-risk area in any hospital for HAIs due to invasive devices, immunocompromised patients, and intensive procedures. NABH assessors specifically review ICU infection control practices, HAI surveillance data, and corrective action evidence.

The key principle: Clean Hands + Aseptic Technique + Proper Device Care + Environmental Cleaning = Effective ICU Infection Control.

1. Hand Hygiene – The Most Important Intervention

Hand hygiene is the single most effective intervention to prevent HAIs. NABH requires compliance with the WHO 5 Moments for Hand Hygiene in all clinical areas, especially ICU.

The 5 Moments are: Before touching a patient, Before clean/aseptic procedure, After body fluid exposure risk, After touching a patient, After touching patient surroundings.

• Perform hand hygiene before and after every patient contact
• Use alcohol-based hand rub or wash with soap and water
• Hand hygiene compliance must be audited and documented monthly
• Target compliance: 80% or above

2. Personal Protective Equipment (PPE)

• Wear gloves, masks, gowns, and eye protection as required by procedure
• Change PPE between patients — never reuse single-use PPE
• Dispose of used PPE appropriately in yellow category waste
• PPE use must be monitored and staff trained regularly

3. Device-Associated Infection Prevention

Central Line Care (CLABSI Prevention)

• Maintain aseptic technique during insertion — use maximal sterile barrier
• Perform daily assessment for line necessity — remove when not needed
• Change dressings as per protocol (typically every 7 days for transparent dressings)
• Disinfect catheter hub before each access
• Track CLABSI rate per 1,000 central line days

Urinary Catheter Care (CAUTI Prevention)

• Insert only when clinically indicated — avoid unnecessary catheterization
• Maintain a closed drainage system at all times
• Provide daily catheter care and remove as early as possible
• Keep drainage bag below bladder level
• Track CAUTI rate per 1,000 urinary catheter days

Ventilator Care (VAP Bundle)

• Head-end elevation 30-45 degrees unless contraindicated
• Daily sedation assessment and spontaneous breathing trials
• Oral care with chlorhexidine as per policy
• Suctioning using aseptic technique
• Track VAP rate per 1,000 ventilator days

4. Environmental Cleaning

• Clean and disinfect high-touch surfaces regularly (minimum twice daily in ICU)
• Ensure proper biomedical waste segregation at point of generation
• Maintain ICU equipment disinfection schedules with documentation
• Terminal cleaning after patient discharge from ICU bed

5. Isolation Precautions

• Follow contact, droplet, or airborne precautions as indicated by diagnosis
• Use dedicated equipment for isolated patients whenever possible
• Display isolation signage clearly at room/bay entrance
• Document isolation start and end dates in patient record

6. Sterilization and Disinfection

• Sterilize reusable instruments according to hospital policy (autoclave/ETO)
• Use approved disinfectants for equipment and surfaces at correct dilutions
• Monitor sterilization records — Bowie-Dick test, biological indicators
• Never use expired sterilized instruments

7. Antibiotic Stewardship

• Use antibiotics only when prescribed and indicated
• Send cultures before starting antibiotics whenever possible
• Review antibiotic therapy based on culture reports — de-escalate appropriately
• Track antibiotic consumption patterns as part of AMR stewardship

8. Staff Education and Surveillance

• Conduct regular infection control training for all ICU staff
• Monitor ICU infection rates (CLABSI, CAUTI, VAP, SSI) monthly
• Perform infection control audits and provide feedback to staff
• Report HAI data to IPC committee and management

9. Visitor Control

• Restrict unnecessary visitors in ICU
• Educate visitors regarding hand hygiene and PPE use before entering
• Prevent visitors with infectious illnesses from entering the ICU
• Document visitor policy and compliance

NABH HAI KPIs for ICU

Frequently Asked Questions

How often should HAI surveillance be done in ICU?

NABH requires ongoing HAI surveillance. ICU HAI rates (CLABSI, CAUTI, VAP) should be calculated and reported monthly to the IPC committee. Trends should be reviewed quarterly with action plans for rates exceeding benchmarks.

What documentation is required for ICU infection control under NABH?

Required documentation includes: HAI surveillance records, hand hygiene audit reports, device bundle compliance checklists, environmental cleaning logs, sterilization records, isolation records, antibiotic stewardship reports, and staff training records. All must be available for NABH assessment review.

What is the VAP bundle as per NABH?

The VAP (Ventilator-Associated Pneumonia) bundle is a set of evidence-based practices that when implemented together significantly reduce VAP rates. The core elements are: head-of-bed elevation (30-45°), daily sedation vacation and spontaneous breathing trial assessment, oral care with chlorhexidine, subglottic secretion drainage (where available), and DVT prophylaxis.
