What precautions should be taken to prevent scabies transmission when interacting with a patient?

Preventing Scabies Transmission When Seeing a Patient

When interacting with a patient who may have scabies, healthcare providers should wear gloves for all patient contact and practice thorough hand hygiene before and after the encounter to prevent transmission.

Standard Precautions for Scabies Prevention

Hand Hygiene

• Use alcohol-based hand rub or wash hands with soap and water before and after each patient contact 1, 2
• Hand hygiene is the single most important method of preventing transmission of infectious agents 1
• When hands are visibly soiled, wash with soap and water for at least 15 seconds 2
• Perform hand hygiene immediately after removing gloves 1

Glove Usage

• Wear medical gloves for all contact with patients suspected of having scabies 1
• Use a new pair of medical gloves for each patient 1
• Remove gloves promptly after use and perform hand hygiene immediately 1
• Do not wash or reuse gloves 1
• Ensure appropriate gloves in the correct size are readily accessible 1

Additional Protective Equipment

• For crusted (Norwegian) scabies, which is highly contagious:
  • Wear a gown that covers personal clothing and forearms 1
  • Consider using a surgical mask if close face-to-face contact is anticipated 1
  • Change protective clothing immediately if visibly soiled 1

Specific Scabies Considerations

Transmission Risk

• Scabies is highly contagious and transmitted through direct skin-to-skin contact 3, 4
• Approximately 15-20 minutes of direct skin contact is needed to transfer mites 4
• The mite cannot survive more than 24-36 hours away from human skin 5

High-Risk Settings

• Be particularly vigilant in:
  • Nursing homes and hospitals 3
  • Settings with patients requiring extensive hands-on care 3
  • Crowded communities 6
  • Areas with immunocompromised patients 6

After Patient Contact

• Remove all protective equipment before leaving the patient care area 1
• Perform thorough hand hygiene 1
• Document suspected scabies cases promptly to facilitate early treatment and prevent outbreaks 3

Common Pitfalls to Avoid

• Failing to recognize scabies early (it can mimic many dermatological conditions) 3
• Neglecting hand hygiene between patients 1
• Reusing gloves between patients 1
• Touching environmental surfaces (doorknobs, charts, computers) while wearing contaminated gloves 1
• Underestimating the contagiousness of crusted scabies in immunocompromised patients 6

By following these precautions consistently, healthcare providers can effectively prevent the transmission of scabies while providing necessary care to affected patients.
