Study Notes
Definition
- Nosocomial infection refers to infections acquired in a healthcare setting, emerging between 48 hours and four days after admission.
Causes
- Hospitalized patients universally face infection risks due to treatment or surgical procedures.
- High-risk groups include young children, the elderly, and those with compromised immune systems.
- CDC reports a 6.1% infection rate among children in intensive care, mainly linked to venous catheters and ventilator-associated pneumonia.
- Key risk factors for children:
- Parenteral nutrition
- Extended use of antibiotics (over 10 days)
- Invasive devices
- Unsatisfactory postoperative status
- Immune dysfunction
- Common risk factors for both adults and children:
- Extended hospital stays
- Severity of underlying illnesses
- Poor nutritional or immune status
- Indwelling catheters
- Inadequate hand hygiene among healthcare workers
- Emergence of antibiotic-resistant bacteria due to antibiotic overuse
- Invasive procedures commonly increasing infection risk include:
- Urinary bladder catheterization
- Intubation or mechanical ventilation
- Gastric drainage tube placement
- Intravenous (IV) medication or transfusion delivery
Symptoms
- Fever often serves as the initial indication of infection.
- Additional signs may include:
- Rapid breathing
- Mental confusion
- Low blood pressure
- Decreased urine output
- Elevated white blood cell count
- Urinary tract infections (UTIs) may cause painful urination and cough difficulties.
- Localized infections can manifest as swelling, redness, and tenderness near surgical or open wounds, potentially advancing to severe muscle tissue destruction and sepsis.
