Not to mention people would arrive at their 10 minute appointment with a list of 5 completely separate medical issues that they'd been saving up for months. So either you do a full history, examination, diagnosis and treatment plan +/- prescription in 2 minutes for each problem, or the 10 minute appointment just becomes a 20 minute appointment. And then you document everything in your lunch break or after you're supposed to have gone home 🙃

Here in the US, the last time I went to a doctor's office they had signs posted saying that those under free healthcare could only discuss a single issue per billed visit. Which sure, saves the medical staff a ton of time and scheduling problems, but also means the most vulnerable (and least able to take time off to visit the doctor) have to prioritize health issues and let minor ones go untreated/undiagnosed until they become major ones.

Healthcare is a mess.
