What is essential for a user before they can access a computer in the ED?

A user must sign in each time they sit down to access a computer in the Emergency Department (ED) because this practice ensures security and confidentiality of patient information. In sensitive environments like healthcare, it is crucial to maintain strict access controls to protect patient data. By requiring users to sign in each time, the system verifies the identity of the individual accessing the computer, ensuring that only authorized personnel can view or handle sensitive information. This measure helps prevent unauthorized access and potential breaches of privacy.

Other practices may be valuable in different contexts, such as online training or registering credentials, but the immediate necessity in an ED environment emphasizes user verification through consistent sign-ins to maintain security protocols effectively.
