This video discusses the roles and responsibilities of Trained Observers. A Trained Observer is a clinician, most likely an infection prevention professional, nurse, or physician, whose sole responsibility is to guide healthcare workers as they don (put on) and doff (take off) personal protective equipment (PPE) for caring for a suspect or confirmed Ebola patient. When acting as a Trained Observer you will not be delivering care directly to patients. Instead you will focus on ensuring the safety of healthcare workers. This video is intended to supplement CDC's Guidance on Personal Protective Equipment To Be Used by Healthcare Workers During Management of Patients with Ebola Virus Disease in U.S. Hospitals, Including Procedures for Putting On (Donning) and Removing (Doffing), available at http://www.cdc.gov/vhf/ebola/hcp/procedures-for-ppe.html. This video will be updated and refined on an ongoing basis based on user feedback and best practices in managing patients with Ebola in U.S. hospitals.
