What does an interface message contain?

An interface message contains data that often pertains to significant events within a system, such as a patient being admitted to the hospital. This type of message is essential for integrating various components or systems, enabling them to communicate crucial information that can impact patient care and operational processes.

In the context of healthcare systems, interface messages are used to transmit real-time data between applications, ensuring that all relevant parties have immediate access to important patient information. This can include key details necessary for treatment decisions, workflow adjustments, and ensuring continuity of care.

While other choices mention important aspects of system operation or user guidance, they do not encapsulate the primary function of interface messages, which is to convey event-driven data critical for operational efficiency and clinical decision-making.
