“A document is designed to be persistent for long periods of time, whereas messages are more often expected to be transient. There is a place for both of these constructs in healthcare.”
Messages areA Message is sent in a context of a conversation between the sender and the recipient. These are typically system level transactions, I just don't think that is an important characteristic. The context of the transaction is an important factor to understanding the message by the recipient. Messages tend to be used in a STATEFUL world. A good example is the NAK message, it is totally dependent on knowledge of the message that is being negatively acknowledged. An order message is expecting that it is starting the state of something being done. It is true that there are some messages that don't fit this. I am not trying to setup absolutism, but rather setting general observations.
- Persistence – Documents are persistent over time. The content of the document does not change from one moment to another. A document represents information stored at a single instance in time.
- Wholeness - A document is a whole unit of information. Parts of the document may be created or edited separately, or may also be authenticated or legally authenticated, but the entire document is still to be treated as a whole unit.
- Stewardship –A document is maintained over its lifetime by a custodian, either an organization or a person entrusted with its care.
- Context - A clinical document establishes the default context for its contents
- Potential for authentication - A clinical document is an assemblage of information that is intended to be legally authenticated.
