"When & How Medical Assistants Should Perform Hand Hygiene: CDC Standard Precautions"

Hand hygiene is a cornerstone of infection prevention and control in healthcare settings. The Centers for Disease Control and Prevention (CDC) recommends that medical assistants perform hand hygiene at key moments to prevent the spread of healthcare-associated infections. This article delves into the CDC's standard precautions and outlines when medical assistants should perform hand hygiene.

Understanding CDC's Standard Precautions

The CDC's standard precautions are designed to reduce the risk of transmission of infectious agents from both recognized and unrecognized sources. They apply to all patients, regardless of their diagnosis or presumed infection status. Medical assistants play a pivotal role in adhering to these precautions, with hand hygiene being a critical component.

When Should Medical Assistants Perform Hand Hygiene?

Before Patient Care

Hand hygiene should be performed before touching a patient, their immediate surroundings, or their personal items. This helps prevent the transfer of microorganisms from the medical assistant's hands to the patient. It's crucial to remember that hands can become contaminated with microorganisms from the environment, other patients, or the medical assistant's own body.

After Patient Care

Hand hygiene should also be performed immediately after caring for a patient. This includes after touching the patient's intact skin, mucous membranes, non-intact skin, or wound dressings. It's also necessary after removing gloves, as they can become contaminated on the outside.

After Exposure to Body Fluids

Hand hygiene is required after exposure to blood, bodily fluids, secretions, or excretions. This can occur during procedures like venipuncture, wound care, or when handling soiled items. Medical assistants should also perform hand hygiene after blowing their nose, coughing, or sneezing.

After Handling Contaminated Items

After touching items or surfaces that are likely to be contaminated, such as medical equipment, bedpans, or blood pressure cuffs, hand hygiene should be performed. This helps prevent the spread of microorganisms to other patients or surfaces.

When Moving Between Patients

To prevent cross-contamination, medical assistants should perform hand hygiene when moving from one patient to another. This is especially important if there will be a delay of more than a few minutes between patient interactions.

CDC-Recommended Hand Hygiene Techniques

Medical assistants should use either an alcohol-based hand sanitizer that contains at least 60% alcohol or soap and water for hand hygiene. The choice depends on the situation and the availability of both options. The CDC provides detailed instructions for both techniques.

Importance of Proper Technique and Duration

Proper hand hygiene technique and adequate duration are crucial for effectiveness. The CDC recommends scrubbing hands with soap and water for at least 15 seconds, or using an alcohol-based hand sanitizer until hands are dry. Rubbing hands palm to palm, between fingers, and around nails helps ensure all surfaces are covered.

When to Use Gloves

While gloves can protect medical assistants' hands, they do not replace the need for hand hygiene. Gloves should be worn when touching bodily fluids, contaminated items, or when performing procedures that may cause exposure to blood or bodily fluids. However, gloves can become contaminated, so hand hygiene should be performed after removing them.
