Is Physician-Patient Privilege practiced anywhere besides the U.S?

[lolkeinthatsghey]

I am planning on doing my TOK essay around Physician-Patient Privilege and would like to understand if this is practiced anywhere else around the world.

What is it? Medical confidentiality where any communication between a physician and patient is protected against use in court. (Even if a person confesses to a psychiatrist that he/she kill someone, the psychiatrist cannot tell this to local authorities without the patient's consent.) 

If there's something similar in your country, please state what it is and how it works in your country.

Thanks!
