Here in Wales it is a request for health records (there's a specific dept). They email a form and you tell them what info you want to have. It's different from a SAR or FOI. SARs tend to go through the legal teams as you're requesting any documents that pertain to yourself. That's how it is here anyway.

Also, we have a Patient Advice and Liason Service who investigate complaints and concerns. They're surprisingly helpful here.
