A set of Communications among individual Care Team Members as they coordinate their activities for the execution of the Care Plan. The current intent of this class is to provide a record of such communications. It is envisioned that this structure could be used in the future to record negotiations among Care Team Members (especially between members belonging to different organizations) as the Care Plan is formulated. The ability to negotiate between Care Team Members does not exist in an automated fashion today, but would be an important feature in future systems. "A conversation organizes individual communications in a meaningful manner for the benefit and understanding of care plan stakeholders." - HL7 Care Plan Domain Analysis Model
