Meeting Notes

• Data Requirements Analysis: Ioana reviewed the notation and data elements in the workflow analysis.

Ben asked if we will use the Rosetta code. Ioana stated that we plan to use Rosetta and are considering mapping to LOINC and SNOMED-CT. We will mine the existing codes in Rosetta for anything pertaining to device measurement and possibly qualifiers. The recommended terminology is IEEE, but we recognize that most devices do not use this. Once we have the requirements defined, we can leverage or expand on Rosetta. Lee Winslow asked if we have considered how to human-validate the data coming through. Ioana stated that we discussed verification during previous meetings. Verification occurs either at the point of care or on the information system for continuously sent data. Lee stated that devices in the future may require this data at the point of care. He asked if we are keeping a pathway back so that data can be sent back to a device that might need data from another advice. Ioana stated that the use case does not include devices querying for data. Rob Rawlins discussed the inclusion of a notice that data is delayed. Ioana asked if something has not really been measured if we need to see it. Sean stated that if the data is being reported it would be misleading if it's not based on physiological data from the patient. There should at least be a flag or notification that this data is not current. Ben stated that a device will not report a value unless it is physiologically valid but a device will continue to report a value while it attempts to record a new value within the allowable time period. Ioana asked what should be done with delayed data when a clinician goes in to validate the data. Rob stated that it should be kept along with the flag. Ioana stated that "delayed" sounds misleading. Rob stated that he would research the FDA standard. Rob asked if other data such as respiration rate would be reported. Ioana stated that anything recorded by the pulse oximeter should be included. Ioana asked if type of sensor should be included. Rob agreed that it is important, especially for determining if the sensor was placed correctly. Toni Philips recommeded Dr. Jim Edwards as a contact for information about the operating room because this is different from critical care. Tom recommended including a variability index. Ioana added body site, body position, and pulse attributes based on participant input.

• Action Items:

1. Toni will reach out to Dr. Edwards and Dr. Gunnar regarding the operating room. Ioana will provide her with background information.
2. Rob will send Ioana information about delayed data as well as the distinction between alarms, events, and alerts.
