A Step-by-Step Guide to Preventing PPE-Related Skin Damage

* Level 1 is normal, intact skin.

* In level 2, the skin is still intact but it is reddened, indicating some underlying tissue damage.

* The highest, level 3, is non-intact skin of any degree.

The red marks from pressure that commonly appear upon PPE removal are known as reactive erythema (Figure 2) and should show resolution within 20-30 minutes. If the erythema doesn't fade away, it suggests level 2 damage. Do not rub or massage erythematous skin. Non-blanchable erythema suggests that underlying tissue damage has already occurred, and rubbing can exacerbate it.

Skin erythema after removal of goggles and mask

For each of these three levels, we offer a stepwise approach to prevention and management.

Level 1

This is when prevention will be most effective. For both airtight and non-airtight PPE, after washing your face, we recommend moisturizing the skin at least daily with a product of choice. Creams containing acrylate polymers or dimethicone are good options for this because of longer durability. We don't recommend ointments, including zinc. Apply moisturizer to areas of the face that have the most contact with PPE, such as ears, forehead, and nose. Whatever product you use, it must be applied 1 to 2 hours before donning PPE so that it is fully absorbed and completely dry before the PPE is put on. The best time is right after showering or washing your face, at home before you go to work. If you use cosmetics, avoid oil-based foundation. Petrolatum products (such as Vaseline) are likewise not recommended.

Then, 5 minutes before applying goggles or mask, apply an alcohol-free skin barrier wipe (also known as liquid skin protectants or sealants) to your face, covering the areas most likely to be affected by PPE (the "T-zone"), avoiding the eyes and mouth. Allow this to dry for 1 minute so that it is no longer tacky to the touch before donning PPE. Many different brands of alcohol-free skin barrier products are available; we don't recommend using a spray on the face because it's hard to control where it goes.

As much as possible, HCPs should remain hydrated for general skin health.

Level 2

For HCPs with non-blanchable erythema, but with skin still intact, the recommendations are the same. Use a moisturizer, allow it to dry, and apply a skin barrier wipe before donning PPE. The type of mask being worn should dictate a decision about use of any additional dressing between the skin and mask. Note that the skin barrier wipe will reduce shearing, but it won't alleviate pressure.

Underneath surgical masks, a dressing of some type can be used to cushion the skin from the pressure of the mask. Options include a thin adhesive foam dressing, a silicone adherent sheet (perforated or nonperforated), and a thin hydrocolloid sheet. Whatever type is used, it should be as low-profile as possible, and cut to cover the desired area (patterns for cutting these dressings can be found in the best practices document, along with other tips about application, assessment, and removal of dressings).

Underneath N95 masks, a dressing could interfere with the effectiveness of the mask by disrupting the airtight seal. Therefore, before applying a dressing, the HCP should check with the facility's health and safety department for approval and arrange for fit testing with the dressing in place. If use of a dressing is approved, use a thin, low-profile, semi-occlusive dressing.

Level 3

HCPs with areas of non-intact skin should follow the same routine for preventive skin care, and follow the recommendations for the use of dressings under the mask. If open wounds are present, some type of dressing might be necessary.

We also don't recommend the use of topical skin adhesives or glues. They can be difficult to remove.

Once the skin is broken, it is unlikely to heal if the HCP continues working in the same area and wearing the same PPE. Few nurses have enough days off between shifts for their skin to fully heal, and even if it does, it's very fragile and will break down again when the nurse goes back to work.

Points of skin pressure with wounds caused by a mask

Nurses need to speak up to their managers and health and safety supervisors. Show them what you are going through. Show them your face. You are the walking wounded.

Can you recap the skin care sequence you recommend for nurses and other HCPs who must wear PPE at work?

Sequence:

1. At home (before you leave for work or 1 to 2 hours before you will be donning PPE):

  • Wash your face and hands well; dry thoroughly

  • Apply moisturizer to face and hands; should be completely absorbed

2. At work, before donning PPE:

  • Apply skin barrier wipe to dry face: forehead, nose, cheeks, ears (if needed)

  • Let dry 90 seconds, until no longer tacky

3. Don PPE.

Your educational program mentions that HCPs who have preexisting skin conditions may find that these are exacerbated by PPE use. Can you explain?

Frequent skin cleansing causes dermatitis of the hands of many nurses — reddened, painful, itchy even bleeding skin on the back of the hands. This type of occupational skin injury often occurs in HCPs, especially during the winter. Frequent handwashing and glove-wearing can result in breaks in the skin, which then serve as another entry point for the virus.

Nurses who are prone to such skin conditions as eczema or psoriasis are reporting more problems now as a result of repeated handwashing and glove wearing.

If you don't take care of your skin, you are going to have skin breakdown.
