Which of the following does NOT occur in the data processing workflow?

The correct choice highlights an aspect of the data processing workflow that typically does not take place. In the context of data processing workflows within Epic systems, the majority of actions are automated to ensure efficiency and accuracy, with manual input generally being limited. Filtering of messages by manual input is not a standard or common practice since it can introduce human error and slow down the overall process.

The creation of HL7 messages from Chronicles is a critical component of the workflow, as HL7 messaging standards are essential for the interoperability of health information systems, enabling the exchange of clinical data across different platforms. Similarly, filing data into Chronicles is a fundamental step in organizing and storing patient information, making it accessible for future use. Lastly, packaging of messages for interconnect delivery is vital to ensure that the messages are formatted correctly for transmission, allowing seamless integration with other healthcare systems.

In summary, while the processing workflow encompasses several automated and structured processes designed to enhance data handling, manual input for filtering messages does not fit within this well-defined pathway, making it the correct answer for what does not occur in the data processing workflow.
