Nosocomial Infections Overview

Definition

• Nosocomial infections: Infections acquired in a healthcare setting, such as hospitals or clinics, during the course of treatment for other conditions.

Key Characteristics

• Occur 48 hours or more after admission.
• Can result from bacteria, viruses, fungi, or parasites.
• Often resistant to antibiotics due to prior use in healthcare settings.

Common Types

1. Urinary Tract Infections (UTIs)
   • Frequently associated with catheter use.
2. Surgical Site Infections (SSIs)
   • Develop at or near surgical incision sites.
3. Pneumonia
   • Often occurs in mechanically ventilated patients.
4. Bloodstream Infections (BSIs)
   • Can be caused by intravenous lines or central catheters.

Risk Factors

• Prolonged hospital stays.
• Invasive procedures (e.g., surgeries, catheterizations).
• Immunocompromised patients.
• Use of broad-spectrum antibiotics.

Prevention Strategies

• Strict hand hygiene protocols for healthcare workers.
• Proper use and maintenance of invasive devices.
• Regular cleaning and disinfecting of hospital environments.
• Implementation of infection control programs.

Diagnosis

• Isolation of pathogens from infected sites.
• Clinical assessment and laboratory tests.

Treatment

• Targeted antibiotic therapy based on susceptibility.
• Supportive care as needed (e.g., fluids, respiratory support).

Surveillance

• Monitoring of infection rates in healthcare settings.
• Reporting protocols to track and manage outbreaks.

Importance

• Nosocomial infections contribute to increased morbidity, mortality, and healthcare costs.
• Understanding and addressing these infections is crucial for patient safety and quality of care.
