Appointment management that actually works for healthcare.

Diarybook reduces missed appointments, shortens waiting lists, and takes the administrative burden off your team — without replacing the systems you already have.

Two layers. One outcome.

At its heart, Diarybook is an advanced messaging platform — automatically reaching patients by the right channel at exactly the right moment.

SMS Email Voice Letter

For organisations with existing systems, Diarybook integrates directly — adding intelligent, automated patient communication without disrupting what's already there.

For those who want the full experience, Diarybook's scheduling portal sits on top — giving clinical and administrative teams a complete appointment management system, built for the real complexity of healthcare.

Either way, the result is the same: fewer missed appointments, less time spent on the phone, and a waiting list that moves faster.

The problem is bigger than most people realise.

In the UK, 8 million appointments were missed in 2023–24 alone. The average NHS trust loses over £8.2 million per year — and behavioural messaging interventions have been shown to reduce missed appointments by up to 30% at minimal cost.

In Ireland, Department of Health research found that behaviourally informed SMS reminders reduced missed appointment rates by 13% — with the potential to save €11.6 million annually if adopted nationally. The HSE's own Outpatient DNA Strategy now mandates SMS reminders as standard practice.

Diarybook is already doing this work — live across the HSE, and in private hospitals and practices across Ireland and the UK.
