What term describes the notification system when a user looks up a patient with the same last name?

The term that describes the notification system when a user looks up a patient with the same last name is "trigger." In health information management and compliance, a trigger refers to an event or condition that prompts an alert or notification regarding a specific activity. When a user accesses a patient's record with the same last name as another patient, this action can trigger a system to notify compliance personnel or relevant stakeholders about the potential for information access or misuse concerns.

This is particularly important in maintaining patient privacy and ensuring that access to sensitive health information is monitored. The use of triggers helps organizations to identify patterns or behaviors that may indicate a risk of inappropriate access, fostering compliance with health information privacy regulations.
