Infection Control Overview•
UNIT I Question 1 Hospital Acquired Infection (HAI) 1. Definition Hospital Acquired Infection (HAI), also known as Nosocomial Infection or Healthcare-Associated Infection (HCAI), is an infection that develops in a patient during hospitalization and was not present or incubating at the time of admission. HAI usually occurs: 1. After 48 hours of hospital admission. 2. Within 30 days after surgery (up to 90 days if an implant is inserted). 3. Within 3 days after discharge. 2. Types of HAI 1. Catheter-Associated Urinary Tract Infection (CAUTI) 2. Surgical Site Infection (SSI) 3. Ventilator-Associated Events (VAE) / Ventilator-Associated Pneumonia (VAP) 4. Bloodstream Infection (BSI), including Central Line-Associated Bloodstream Infection (CLABSI) 5. Hospital-Acquired Pneumonia (HAP): Pneumonia occurring ≥48 hours after hospital admission in patients not on mechanical ventilation. 6. Clostridioides difficile (C. difficile) Infection 3. Causes 1. Poor hand hygiene
2. Contaminated medical equipment 3. Improper sterilization and disinfection 4. Invasive procedures 5. Long hospital stay 6. Antibiotic-resistant microorganisms 7. Poor environmental sanitation 8. Overcrowding in hospitals 4. Risk Factors 1. Contaminated hospital environment 2. Invasive procedures (catheters, ventilators, surgery) 3. Weak immunity 4. Elderly and newborn patients 5. Diabetes and other chronic diseases 6. Antibiotic-resistant organisms 7. Prolonged hospitalization 5. Signs & Symptoms 1. Fever 2. Redness and swelling 3. Pain 4. Pus discharge 5. Burning urination 6. Cough and breathlessness 7. Diarrhea (especially with C. difficile) 8. Raised WBC count
6. Prevention and Nurse's Role 1. Perform proper hand hygiene before and after patient contact. 2.

CLABSI Bundle (Central Line-Associated Bloodstream Infection) Before Insertion 1. Perform proper hand hygiene. 2. Use maximal sterile barrier precautions (cap, mask, sterile gown, sterile gloves, and full-body sterile drape). 3. Select the most appropriate insertion site to minimize the risk of infection. During Insertion 1. Follow strict aseptic technique. 2. Prepare the skin with chlorhexidine antiseptic before inserting the central line. After Insertion (Maintenance Bundle) 1. Maintain a clean and sterile dressing over the insertion site. 2. Inspect the insertion site daily for redness, swelling, pain, or discharge. 3. Disinfect the catheter hub before each use. 4. Review the need for the central line every day.
5. Remove the central line as early as possible when it is no longer required. Expected Outcomes 1. Reduces the risk of Central Line-Associated Bloodstream Infection (CLABSI). 2. Improves patient safety. 3. Reduces bloodstream infections. 4. Decreases complications and mortality. 5. Nurse's Role 1. Follow every care bundle completely and consistently for every eligible patient. 2. Perform proper hand hygiene before and after patient care. 3. Maintain aseptic technique during all procedures. 4. Use appropriate PPE whenever required. 5. Assess the daily need for urinary catheters, central lines, and ventilators, and report when they can be safely removed. 6. Monitor patients regularly for early signs of infection. 7. Educate patients and caregivers about infection prevention. 8. Document all nursing care accurately. 9. Report any signs of infection or failure to follow the care bundle immediately. Note: A Care Bundle is effective only when all its components are performed together and consistently for every eligible patient. Skipping even one component reduces the effectiveness of the bundle and increases the risk of Hospital Acquired Infections (HAIs).
Question 3 Surveillance of Hospital Acquired Infection (HAI) 1.
