Requirements for an Universal Encounter model

See also Helse Vest Patient Encounter issues, and this video.

After studying the requirements of Helse Vest (Norway), CSC (Denmark), Germany (mainly influenced by SAP and their billing requirements), and the US, a universal encounter model should consist of the following levels of granularity:

1. Physical location
2. Service encounter
3. Organizational encounter
4. Encounter grouper

2 Service Encounter

Note: the service encounter and the organization encounter are quite often grouped into one single encounter Act (e.g. HL7 version 2). Effectively we then have three levels of granularity.
