Greetings endocrinologist: Trying to answer your questions--
1. As Bert said. Hopefully one of fellow endocrinologist will respond.
2. It can interface with few PMS. I do not know the list. But if you have downloaded AC, go to admin section, see under interfaces and you get a list of all interfaces available and also ones in works.
3. None as far as I know. But you really do not need AC to do that. We have developed flow sheets for (takes maximum 5 minutes to develop one). I prefer wordpad and not pdf as you cannot enter/delete in pdf unless you have I believe professional edition of adobe at 100s of dollars.
(a) coumadin for PT/INR.
http://www.aafp.org/fpm/20050500/77asys.html. You open wordpad on your pc, create tables with headings suggested in this article, put in one area where anybody in your office can import to that patients chart, then start using that. When I get INRs, I fill out the current dose, next dose, next check, forward the chart to my nurse, who calls patient, enters patient contacted and initials. She saves using the save button on top. I your workstation has MS word, it will open on right side of imported section, if it has no MS word, it will pop up as new screen.
(b) referral log: same wordpad, import. Has the following headings:
Referred to/test
Date/time
Reason
Number of visits
Insurance
Authorization number
Patient aware
Initials of referral clerk.
(c)You could develop in word pad- using this (I may be preaching to choir here)
http://www.aafp.org/fpm/20000600/diabetesflowsheet.pdfThis is in pdf. I would do in wordpad. Not done yet. One of my do list.
(d). Real primary care. May this is not useful to you as specialist.

http://www.priorityhealth.com/provider/clinical/diabetesI remember seeing Quest and labcorp on the interface list as mentioned above in admin section/interface tab.
4. Data/format. If I guess what you are asking for- it is MS access. Works fine for small doctors offices, we have 7 users at one time maximum, works fine. If you are thinking of an exit strategy, I would print the entire chart to pdf and import to new EMRs. I do not see any reason to do that. We have AC for 3 yrs, going strong. PAPERLESS. Easy backups and restoration. Even expensive EMRs which cost 10000$ (I do not want to name names) does protime/INRs as mentioned above.

Jon can build you custom interface for a price if you ask him.
Good luck
Internist.
