Which outcome occurs when multiple high threshold matches are identified in the system?

When multiple high threshold matches are identified in the system, the primary outcome is that the system becomes aware of a potential ambiguity or conflict regarding patient identities. This situation usually indicates that multiple records may be linked to a single individual, which can complicate patient care and data management.

Logging a fatal error is crucial in this scenario because it alerts the system administrators or healthcare providers to investigate the discrepancies before proceeding. High threshold matches suggest that the system is not simply dealing with routine data entry errors; rather, significant issues may raise concerns about patient safety or data integrity. By logging a fatal error, the system ensures that immediate attention is given to these matches to resolve any confusion and ensure accurate patient records.

While other options like creating a new patient file or notifying healthcare providers may seem like appropriate actions in other contexts, they do not address the complexity and seriousness that come with high threshold matches. These choices could further complicate the situation rather than help rectify it. Thus, the act of logging a fatal error is a protective measure that prioritizes patient safety and accuracy in the healthcare system.
