Access control is the mechanism that determines who can access an electronic health record and how. Each user has a unique ID so every action is tied to a specific person, providing accountability. Emergency access procedures allow clinicians to reach necessary records in urgent situations without bypassing the auditing requirements. Automatic log-off helps protect unattended devices by ending sessions after inactivity. Encryption and decryption ensure that data remains confidential, readable only by authorized personnel with the proper keys. While identity management, encryption standards, and audit trails cover parts of these protections, access control brings these elements together to govern authentication, authorization, and safeguarding of data in everyday use.
