When should hands be washed in a healthcare setting?

Hand hygiene in a healthcare setting is crucial to prevent the transmission of infections. Washing hands before and after contact with patients is vital for several reasons. First, it protects patients by significantly reducing the risk of transferring pathogens from healthcare workers to patients. This is especially important for those who may be vulnerable due to illness or compromised immune systems.

Additionally, washing hands after contact with patients helps to prevent the spread of infections from one patient to another or to the healthcare worker themselves. This practice is guided by the principles of infection prevention and control, emphasizing the importance of maintaining a clean environment for both patients and healthcare staff.

The other options fall short in ensuring comprehensive infection control. Washing hands only when visibly dirty does not take into account the bacteria and viruses that may be present but not visibly apparent. Limiting handwashing to only after patient care neglects the critical time before contact, which is essential to prevent introducing germs to the patient. Lastly, washing hands only upon leaving the facility undermines the ongoing risk of transmission that can occur during patient interactions. Therefore, the practice of washing hands before and after patient contact is a foundational aspect of safe healthcare delivery.
