I totally agree with you ‘Pacharapol’
Sometimes, before thinking about how to link the patient’s information between the hospitals, there is an argument that who is the real owner of the data. Some data, the hospital or even some government departments do not want to share because of some profits. So, I think this may be one of the reasons why Thai hospitals still have this problem.
If we consider EA, I think each hospital uses each system due to their necessities; and we can’t change the system. However, as everyone knows, a house can be renovated in the same way with the hospital’s system. Maybe the good way is there should have a central system between hospitals and can retrieve only necessary data and the name of testing that the patient used to be done. In the case of the special data, doctor or any health informaticians should have their own authorities to access to see the information. It seems to be difficult but in this era, everything can happen.
