Dear all,

I am quite new in this aria and I have 4 very important questions for you as follows.

For a national EHR system including all medical areas in a country where broadband Internet is in the childhood age and the population is about of 25 milions:


1) How critical is a disater recovery solution if the original site is cluster balanced in an active-active mode? (Please explain the reasoning.)

2) How fast must be the swiching between the production site and the disaster recovery site? (2 seconds, 2 minutes, 2 hours, 2 days etc. Please explain the reasoning.)

3) For a country with let's suppose of 25 milion inhabitants where every person can see its own medical record via Internet browser and where let's say 100 000 medical parcticioners are working every day in EHR how many concurent connections and instant access to the production site should be designed as minimum?

Off course that not everybody is quering or uploading/downloading data in the sistem second by second but statisticaly they are logged into the Main National EHR system (the production site).

How many concurent connections should be provided as minimum in the configuration of a national EHR?

4) How many employers should work in a callcenter(medical related questions) &  helpdesk (IT related questions)?

Are 25 persons enough for a population of 25 milions?

I am looking forward for your profesional views and reply.

Please give me also a reasoning for your answers (and some links to pdf/html/doc documentation will be more than wellcome and appreciated)

Thank you very much!

Best regards,

5) How much space should be statisticaly reserved for health care recording of each person (patient) in EHR? 

Is 1 MB/1 person/1 year enough or is it to small for the purpose of EHR and for nowadays technology?
