Field note · 2026-03-12
The first page of a morning list already shows whether the clinic will run late: mixed new and follow-up, a procedure parked in a ten-minute slot, and a start time that reception cannot honour.
A session list is not a diary of names. It is a claim about time. Each row says a person will be in a room with a named clinician for a stated number of minutes. When the claim is wrong, the waiting area fills and the last patients of the morning are still in chairs when the afternoon list is due to begin.
Start with the mix. A list that places three new patients in the first hour, each coded as twenty minutes, will overrun if those new patients still need a full history, a chaperone, and a letter. Follow-up slots of ten minutes look tidy on the book. They do not survive a conversation about a scan that has not arrived.
Then look at the first appointment. If the clinic is advertised as 09:00 and the first patient is booked at 09:00, there is no time for the room to be set, for results to be printed, or for the nurse to take blood pressure. Many overruns begin in those first twelve minutes and are then blamed on the last patient of the morning.
Unused slots in the middle of a list are easy to miss because the page still looks full. A gap left for a procedure that was cancelled on Friday afternoon often remains coded as booked. Reception cannot offer it. The room still sits empty. When we review a clinic we ask for the list as printed on the day and the list as it stood at 17:00 the night before.
None of this requires a new system. It requires someone to sit with the printed list, the room diary, and the person who actually calls patients through. The questions are ordinary: who was late, who was added, which slot was a procedure in disguise, and whether the DNA was a DNA or a clinic that never opened the door on time.
