What techniques are best for preventing the spread of nosocomial infections?

Proper hand washing is a fundamental and highly effective technique for preventing the spread of nosocomial infections. This practice significantly reduces the number of pathogens on the hands, which can be easily transmitted between patients and healthcare workers. Effective hand hygiene includes using soap and water or an alcohol-based hand sanitizer, focusing on the areas most likely to harbor bacteria, such as under the nails and between the fingers.

While the use of gloves, wearing protective clothing, and minimizing patient contact all contribute to infection control, they are generally considered supplemental methods. Gloves and protective clothing do not replace the need for hand hygiene, as contamination can still occur during their use. Additionally, minimizing patient contact may not always be feasible, particularly in providing necessary care. In contrast, proper hand washing is a universal, simple, and highly effective means of interrupting the transmission of infectious agents in healthcare settings.
