What strategies can reduce the risk of hospital-acquired infections in clinical practice?

• A. Shared equipment without cleaning
• B. Hand hygiene, aseptic technique, isolation precautions, proper device management, environmental cleaning, vaccination, and safe injection practices
• C. Visitors do not need to wash hands
• D. Rely solely on antibiotics

Answer: (B)

Prevention of hospital-acquired infections relies on comprehensive infection prevention and control measures. Hand hygiene is the most fundamental step—clean hands before and after patient contact or after touching potentially contaminated surfaces to break the chain of transmission. Aseptic technique during procedures, dressings, and device insertions minimizes introducing pathogens into sterile sites. Isolation precautions help contain spread when a patient has an infectious condition, using appropriate personal protective equipment and dedicated equipment when needed. Proper device management means using invasive devices only when necessary, removing them promptly when no longer needed, and maintaining sterile technique to prevent biofilm and infection. Environmental cleaning reduces the presence of pathogens on surfaces and in rooms. Vaccination of healthcare workers and patients lowers susceptibility and transmission risk for vaccine-preventable diseases. Safe injection practices prevent contamination of medications and needles, reducing risk to patients and staff. Together, these strategies create multiple barriers to transmission and are the most effective approach to lowering hospital-acquired infections. Sharing equipment without cleaning, allowing visitors to skip hand hygiene, and relying only on antibiotics do not provide these protective effects and can increase risk or resistance.
