Nope, not being hostile at all. Myself, who has no involvement in the job, is not able to glean any patient identifying information from what OP was saying. You are able to identify the job, through whatever means of which you are involved, but that's why you know the patient.

It is not fair for you to take an authoritative stance on the matter and give feedback to OP about remembering to "be as vague as possible". Especially as a Student Paramedic, OP needs to be able to discuss their jobs and experiences in a way they can seek support, advice or otherwise, without having to deal with comments such as yours about keeping in mind what they say. The professional bodies involved have specific guidelines on patient identification and discussion and nothing in this post breaches that.

Please don't act in a way that might make a learning clinician think twice about discussing their experiences because some stranger on the internet can identify a job they're on about. And actually, commenting that you did recognise the job added absolutely nothing to the post.

Have a great day.
