Are there any problems in healthcare or public health process in this situation where there is no enterprise architecture plan for the overall health information system in the province?
A simple example of patients shopping around for treatment in many hospitals would lead to over-reporting of cases, which may lead to false alarm of epidemics. In Germany, I heard that they have set up the EHR long time ago. When the patients move to other cities, they have to report to the authority and their health information will be transferred to the new health care providers automatically. This is their regulations. I agree with Dr. Watcharee on privacy and confidentially issues but I think that It can be overcome with good design. The main issue is to get all stakeholders to spell out their need so that the system can be developed up to GEA LEVEL.
