What the order says and what gets booked: 30 exam guides, for the patient and for whoever books it

Why does the exam name not match what the patient searches for?

A doctor writes gastroendoscopy, the patient searches endoscopy, and the centre has it loaded as upper digestive endoscopy. All three name the same procedure and none of them match each other in a search box. The referring professional sometimes writes the service under a different name than the system uses, and the scheduler who receives the order ends up reading it out loud to guess what should be booked. That is the alias problem, and it produces a silent share of the queue.

On top of that sits what the order does not say. With contrast or without changes the slot, the machine and the preparation for an MRI. Fasting changes the time of day for a lipid panel. Preparation days change the entire date of a colonoscopy. Every guide states those fields explicitly, because they are what makes one appointment get lost twice.

Is this useful if I am a patient?

Yes, and they are written for that. If you are holding an order, the guide tells you what was requested, what it is called in the centre's system, how long it takes, what preparation it demands and what to ask when you call to book. None of that requires understanding the diagnosis behind it.

Every guide ends with the same concrete invitation: ask at your health centre whether they already use Surface. At the centres that do, the appointment gets offered to you instead of chased by you, and the preparation instructions arrive before it is too late to follow them.

How are the 30 guides grouped?

Into the five units where the volume concentrates: radiology, laboratory, gastroenterology, cardiology and dental. Each guide hangs off its unit's page, where the shape of the queue and the preparation burden of the whole service live. The selection came from crossing the most requested with the most confusing, which is exactly where an order falls through.

If you run a centre, two readings complement this family: why booking more can make no-show worse and how completion is measured stage by stage. The vocabulary these 30 guides use is defined in the glossary.
