Figure 1.

Optimized doffing area design. The healthcare worker (HCW; 2) begins doffing while standing on the arrow in the yellow zone (8), facing the mirror (12), at a 90-degree angle to the trained observer (TO; 3). The HCW uses the horizontal grab bar (5) as a balance aid and uses the mirror to self-inspect when removing disposable shoe covers. After each shoe cover is removed, the HCW steps on the chemical mat in the green zone (10) and disposes of the shoe covers in the trash can (9). The TO dictates the doffing steps and visualizes the HCW using the observation windows (4) that are parallel to the path the HCW is intended to follow while doffing. Primary (6) and backup hand hygiene (1) and wipes (7) are within arm’s reach of the HCW, and the red zone (11) marks the contaminated areas. There is enough clearance between the doffing area and the patient bed (13) for the HCW to avoid stepping in the doffing area while providing patient care.
