A discharge letter is mostly copying.

Diagnoses sit in the hospital information system, lab values in the results system, the clinical course in the chart, the medication in the prescribing module. Whoever writes the letter opens each one in turn and copies it into the in-house template. Because every author works in a different order, two letters from the same ward look different.

40minutesThat is how long a discharge letter takes when the sources are compiled by hand.
3text blocksEvery author words the history, course and recommendation differently.
1sign-offThe doctor reads the letter at the end anyway, but until now has been reading raw text rather than a draft.

Before sign-off, all the doctor has left to do is read and correct the three text blocks; writing effort falls by 60%.

The 60% reduction in writing effort is this agent's headline figure. The number of sources, writing time and blocks describe a typical discharge letter on a ward; they are illustrative, not counted.

Three steps through the process.

The treating doctor decides on diagnosis and recommendation; the agent only compiles what has been documented for the stay.

Gather the treatment data for the case

The agent reads the diagnoses, findings, clinical course and medication for the stay from the hospital information system. Every detail it carries over keeps a record of its source.

Case ST3-2026-0812, 5 sources read, 31 details carried over

Build the letter on the in-house template

The agent fills in history, course, findings and recommendation in the order of the in-house template. It uses medical terms exactly as documented.

Draft with 6 sections, every line with a source reference

Hand over the draft for sign-off

The agent files the draft, with references and open passages, in the patient record. The treating doctor reads, amends and signs.

What the agent does not do.

It does not make diagnoses.

It carries over the coded diagnoses, each with its reference in the hospital information system. The treating doctor is responsible for the medical content.

It does not send the letter.

It files the draft in the patient record. The medical records team sends it to the GP or the patient after sign-off.

It adds nothing that is not documented.

If a day's clinical course is left blank, the draft shows an open passage with the date. The doctor fills it in.

The questions that come up before the first meeting.

How quickly is the Clinical Letter Agent ready to use?

A pilot typically runs on your own data within 4 to 6 weeks. The agent connects to your existing systems rather than running as a separate, parallel environment.

Where is the data processed?

EU cloud, private cloud or on-premises. Processing is GDPR-compliant and models are never trained on your data. Details in the Trust Center.

Where does the figure “60% less writing effort” come from?

It is based on experience from comparable projects and process benchmarks, not a commitment. We work out the realistic effect for your organisation during the assessment before the pilot.
