The State of Patient Scheduling

Every missed appointment is a wasted clinic slot that another waiting patient could have used. NHS England has repeatedly highlighted the scale of missed hospital outpatient appointments across a year, and the knock-on cost in lost clinical time. The single biggest lever on the DNA rate is contact: patients who are reminded, and who can easily reschedule, show up more often.

DNA rates are not uniform. They run higher in some specialties, in more deprived areas, and where the only way to change an appointment is to sit in a phone queue during working hours. That last point matters, because it is the part that automation can fix without any change to clinical practice.

Ireland and England publish their waiting lists differently, so the headline totals are not directly comparable — but both are large and both have grown. In England, NHS England's referral-to-treatment statistics track elective pathways; in Ireland, the National Treatment Purchase Fund (NTPF) publishes separate inpatient/day-case and outpatient lists.

A meaningful slice of any waiting list is out of date: patients who have moved, been treated elsewhere, or no longer need the appointment. Validating the list — simply contacting people to confirm they still want to be seen — routinely removes a portion of it, which is faster and cheaper than adding capacity.

Between a referral arriving and a patient being booked sits a long chain of manual steps: opening the referral, triaging it against the right consultant's rules, finding a slot, phoning the patient, phoning again when they do not answer, rescheduling, and confirming. Ireland is modernising this with eReferral and a national digital-health investment, but the last mile — actually reaching the patient — is still overwhelmingly done by hand.
