Which combination best reduces hospital-acquired infections on a unit?

• A. Increased patient isolation measures only
• B. Hand hygiene, sterile technique, and compliance monitoring with feedback
• C. Rely on antibiotics for all patients
• D. Postpone infection control training

Answer: (B)

Reducing hospital-acquired infections relies on a multi-faceted prevention approach that targets how infections spread and how procedures are performed. The best combination includes hand hygiene, sterile technique, and compliance monitoring with feedback. Hand hygiene is the most effective way to prevent transmission of pathogens between healthcare workers and patients. Sterile technique during invasive procedures minimizes contamination that can lead to infection. Monitoring how well staff follow these practices and providing feedback helps sustain correct behavior and quickly address lapses.

Relying on isolation alone misses transmission routes beyond just single-patient exposure. Relying on antibiotics for all patients does not prevent new infections and contributes to antibiotic resistance. Postponing infection-control training undermines ongoing improvement. The integrated approach of hand hygiene, proper sterile technique, and feedback-driven monitoring best reduces HAIs by changing daily practices and sustaining safe habits.
