Abstract: Example systems, methods and machine readable storage media to facilitate locking medical exams in a healthcare system are disclosed herein. An example method for locking a medical exam in a workflow queue for a clinical user includes authenticating the clinical user during a user session. The example method also includes obtaining a user selection of the medical exam in the workflow queue during the user session. The example method also includes associating a permission level to a session user identifier associated with the user session. The example method also includes determining whether the permission level includes clearance to lock the medical exam, and, in response to determining that the permission level includes clearance to lock the medical exam, flagging the medical exam as read-only, wherein the flagged medical exam remains flagged after the clinical user ends the user session.
