Add "health care encounter" and subtypes

[GoogleCodeExporter]

As discussed on the ogms-discuss list, we need a representation of healthcare 
encounters and their subtypes.  And of course, definitions to go along with the 
representations.

I propose the following structure:

Process
  Health care process
    Health care encounter
      Outpatient encounter (synonyms: ambulatory visit, outpatient visit)      
      Inpatient encounter (synonyms: hospital stay, hospitalization)
      Emergency department encounter (synonyms: emergency room encounter, emergency department visit, emergency room visit)

Note that the American Academy of Emergency Medicine seems to prefer the term 
"emergency department" to "emergency room".  It is after all, more than one 
room :-)  So I chose ED instead of ER as the preferred term.

Also, it is tempting to create additional subtypes based on:
1. Reason for the visit (e.g., pre-admission testing prior to surgery, 
conventional care vs. research vs. both)
2. Where the encounter occurs  (e.g., physician's office vs. outpatient 
encounter at the hospital vs. in-store clinics such as MinuteClinic vs. 
free-standing urgent care facilities such as MedExpress)
3. Physician specialty (cardiology vs. dermatology vs. family medicine vs. etc, 
etc.)
4.  Non-physician providers (e.g. physical therapy visit, nutritionist visit)
5.  Type of therapy offered (really just a special case of #1 but I highlight 
it because it is common. Examples: weight control clinic, immunization clinic, 
etc)

and perhaps more...

With respect to #2, of course a hospitalization can occur only at a hospital 
and an ED visit only in an ED, but the nature of the encounters are such as to 
determine the setting (careful watch of ill patients around the clock over a 
time period measuring multiple days requires a hospital), not the other way 
around (encounters occurring at a hospital need not be hospitalizations, indeed 
outpatient encounters occur there).

We need definitions, too, and I'll update the issue with proposed definitions 
ASAP.

Sorry for the multiple emails, but I meant to say that the temptation I 
mentioned is to be avoided, in OGMS at least.   I believe many if not all of 
the additional distinctions lead to attributive collections.

Minor suggestion to root these terms at "processual entity" since "process" may 
disappear in BFO 2, see "Candidates for Dropping" section in

'health care encounter' (with stubs for subtypes) and 'health care process' 
have been added as of OGMS v0.8.
