Which Ppe Should Be Removed Before Exiting The Patient Room

Proper doffing of personal protective equipment (PPE) is a critical infection control measure designed to protect healthcare workers from self-contamination. The sequence of removal is just as important as the sequence of donning, and understanding which PPE should be removed before exiting the patient room is fundamental to breaking the chain of infection transmission. But generally, all PPE except the respirator (such as an N95 or powered air-purifying respirator) must be removed inside the patient room or anteroom. The respirator is the final item removed, and it is taken off only after the healthcare worker has safely exited the contaminated zone and performed hand hygiene.

The Core Principle: Clean to Dirty

The guiding philosophy behind PPE removal is the "clean to dirty" concept. But the front of the gown, the outside of gloves, the front of the face shield or goggles, and the front of the mask or respirator are considered contaminated. The inside of the gown, the inside of gloves, the ties or elastic bands of the mask, and the headband of the face shield are considered clean. The doffing process must see to it that clean surfaces only touch clean surfaces, and contaminated surfaces only touch contaminated surfaces or are disposed of immediately Practical, not theoretical..

Standard PPE Doffing Sequence (Contact and Droplet Precautions)

For standard contact and droplet precautions, the following sequence should be performed inside the patient room, typically near the doorway, before stepping into the hallway The details matter here..

1. Gloves: The First Barrier Removed

Gloves are the most heavily contaminated item. They must be removed first using a glove-to-glove, skin-to-skin technique.

• Step 1: Grasp the outside edge of one glove near the wrist (contaminated touches contaminated).
• Step 2: Peel the glove away from the hand, turning it inside out.
• Step 3: Hold the removed glove in the gloved hand.
• Step 4: Slide fingers of the ungloved hand under the remaining glove at the wrist (clean touches clean).
• Step 5: Peel the second glove off over the first glove, encapsulating the first glove inside.
• Step 6: Discard immediately into the waste receptacle inside the room.
• Critical Action: Perform hand hygiene immediately using alcohol-based hand rub (ABHR) or soap and water if hands are visibly soiled.

2. Gown: Removing the Body Barrier

Once gloves are off and hands are clean, the gown is removed. The front and sleeves of the gown are contaminated.

• Step 1: Unfasten ties or Velcro tabs at the neck and waist. Depending on the gown design, this may require reaching behind the back (clean area) or breaking the neck closure at the front.
• Step 2: Pull the gown away from the neck and shoulders, touching only the inside of the gown (clean touches clean).
• Step 3: Turn the gown inside out as it is pulled down over the arms, rolling it into a bundle.
• Step 4: Discard into the waste receptacle inside the room.
• Critical Action: Perform hand hygiene again.

3. Eye Protection: Face Shield or Goggles

The front of the face shield or goggles is contaminated. The headband or ear pieces are clean Simple, but easy to overlook..

• Step 1: Remove by handling only the headband, ear pieces, or side arms.
• Step 2: Lift forward and away from the face. Do not touch the front lens or shield.
• Step 3: If reusable, place in a designated receptacle for reprocessing inside the room (or just outside if a designated clean table exists in an anteroom). If disposable, discard in the waste receptacle.
• Critical Action: Perform hand hygiene.

4. Mask or Standard Procedure Mask (Surgical Mask)

For droplet precautions using a standard surgical mask, the mask is removed inside the room. The front of the mask is contaminated; the ties or ear loops are clean.

• Step 1: Untie the bottom tie first, then the top tie (or remove ear loops).
• Step 2: Pull the mask away from the face by the ties/loops only.
• Step 3: Discard into the waste receptacle.
• Critical Action: Perform hand hygiene.
• Exit: The healthcare worker may now exit the patient room.

The Critical Exception: Respirators (N95, FFP2, PAPR) for Airborne Precautions

This is the most frequent point of confusion and protocol deviation. Worth adding: **When airborne precautions are in effect (e. g., for tuberculosis, measles, varicella, COVID-19, or aerosol-generating procedures), the respirator must NOT be removed inside the patient room.

Why the Respirator Stays On Until Exit

Airborne pathogens can remain suspended in the air within the patient room for extended periods. Removing the respirator inside the room exposes the healthcare worker’s respiratory mucosa to infectious aerosols. The room itself is the "hot zone" for airborne particles.

Correct Sequence for Airborne Precautions

1. Inside the Room: Remove gloves $\rightarrow$ Hand Hygiene $\rightarrow$ Remove gown $\rightarrow$ Hand Hygiene $\rightarrow$ Remove eye protection $\rightarrow$ Hand Hygiene.
2. Keep Respirator ON.
3. Exit the Room: Close the door behind you.
4. Outside the Room (Clean Area/Anteroom/Hallway): Perform hand hygiene.
5. Remove Respirator: Handle only the straps. For an N95, bring the bottom strap over the head, then the top strap, pulling the respirator away from the face without touching the front filter material.
6. Discard or Store: Discard disposable respirators; store reusable elastomeric respirators or PAPR hoods per protocol.
7. Final Hand Hygiene: Perform hand hygiene immediately after respirator removal.

Powered Air-Purifying Respirators (PAPRs)

PAPR doffing is more complex. The hood/helmet is often removed inside the room (or anteroom) after the gown but before the blower unit/belt. On the flip side, the filter/blower unit remains on the wearer until they exit the room. Specific institutional protocols for PAPR doffing vary significantly based on the model (loose-fitting hood vs. tight-fitting facepiece) and must be followed precisely Worth knowing..

The Role of the Anteroom

Many modern isolation rooms feature an anteroom (a small buffer zone between the patient room and the hallway). The anteroom changes the logistics of where PPE is removed, but not the fundamental sequence.

• Negative Pressure Anteroom (Airborne Infection Isolation Rooms - AIIR): The anteroom is considered part of the contaminated zone regarding air handling. Gowns, gloves, and eye protection are often removed in the anteroom. The respirator is still removed after exiting the anteroom into the clean hallway.
• Positive Pressure Anteroom (Protective Environment): Used for immunocompromised patients. The flow is reversed. PPE removal protocols differ significantly here to protect the patient, not the worker.

If no anteroom exists, all PPE (except the respirator for airborne precautions) is removed at the doorway inside the patient room.

Hand Hygiene: The Invisible Step Between Every Step

It cannot be overstated: Hand hygiene is required between every single step of doffing. Contamination of hands during doffing is the primary route of self-inoculation. Studies using fluorescent markers have shown that healthcare workers frequently contaminate their hands, forearms, neck
