Unfortunately a lot of other countries do it better because they're in a completely different healthcare system. Which is to say that the focus of US EHR systems is billing, the focus in other countries is on patient care. That might sound like a trivial difference, but medical staff at US healthcare providers are required to record significantly more information in order for it to be reimbursed. For example in other countries you aren't recording supply usage on a "by patient" basis, but by ward or even by department. So patient charts are much simpler abroad. So you could copy a foreign EHR system but it would be completely unusable or require so much alteration you might have well start again. The issues are somewhat systemic. Even Medicare which is essentially socialized medicine in the US, has substantially higher documentation requirements than equivalent programs abroad.
