The Good Discharge Letter: A Short Style Guide

Monday, 12:50 p.m., a general practice. Between the last patient of the morning and the round of house calls lie twenty minutes and a stack of mail. On top, the Entlassbrief — the German discharge letter — from an internal medicine department, four pages. The general practitioner is looking for a single piece of information: why the hospital discontinued the apixaban. She finds the new medication list, from which the drug is missing. A reason she does not find. In the afternoon she calls the ward; the colleague who knows the case is off.

For chief physicians, this moment lies outside the field of view — and it concerns them directly. The physician letter (Arztbrief) is the document with which a department appears before those who refer patients to it and continue their care. It is read outside the hospital more often than inside. You can treat it as a tiresome duty at the end of the case, or as a craft with standards of its own. This piece is about the craft.

How letters land with the people who read them

The most thorough German study on the question comes from linguists: in 2019, Bechmann and Riedel of the University of Düsseldorf surveyed 197 general practitioners about the letters that land in their practices [1]. 99 percent reported having received erroneous physician letters; 98.5 percent say they sometimes do not understand letters at first reading; 88 percent consider incomprehensible or erroneous letters a possible source of treatment errors. The numbers want to be read correctly: it is a study report without peer review, the sample small and self-selected, all figures self-reported. An error rate for physician letters cannot be derived from it — but it does show how the receiving side experiences this type of text.

More instructive than the headline numbers is the respondents' list of criticisms: inconsistent structure, vague wording, errors in the medication, missing reasons for therapy and medication decisions, irrelevant detail without context. Add a volume problem: the respondents report reading three to ten letters a day, some investing up to an hour of reading time daily [1].

Internationally, the finding is older and more stable. A systematic review in JAMA showed in 2007: direct communication between hospital and general practice is rare, discharge letters are often not yet available at the first follow-up visit, and they lack information needed for ongoing care [2]. Ask general practitioners what a good letter should contain, and the list becomes remarkably concrete. A 2023 US interview study names: actionable task lists, flagged incidental findings, medication changes with reasons, the planned duration of newly started therapies — and expressly no letters that recount every detail of the stay [3]. As early as 1998, Canadian family physicians clearly preferred structured letters over narrative ones [4].

Five marks of the good letter

The first paragraph belongs to the reader. Why was the patient here, what was decided, what changes for the practice — whoever answers that in the first sentences has done the most important part. The chronology of the stay may follow; it is supporting evidence, not the centerpiece.

Every medication change carries its reason. "Apixaban discontinued after lower gastrointestinal bleeding on July 12; re-evaluation of anticoagulation recommended in four weeks" — a sentence of this kind spares the continuing physician a phone call, and possibly spares the patient more. The missing rationale for medication decisions is among the most frequently named deficiencies in both surveys cited [1,3].

Open points are tasks. The incidental finding — say, the 4 mm pulmonary nodule with follow-up recommended in twelve months — belongs in a marked place, with a responsible party and a time horizon. In line 14 of a findings paragraph it sinks, and the follow-up with it.

Abbreviations are interior architecture. 34 percent of the Düsseldorf respondents encounter unknown abbreviations often or very often [1]. What everyone on the ward understands is riddle prose outside the building. The letter leaves the hospital; its abbreviations should only leave with it if they mean something outside.

Brevity is an achievement. The letter that contains everything is generated faster today than ever. The letter that selects and weighs requires a judgment about what the recipient needs — and precisely there lies its quality.

Style as a stance

These five marks share a common denominator: they treat the letter as a collegial handover to the physician who may care for the patient for the next ten years. Whoever writes this way writes differently — and whoever edits this way, teaches. Correcting a resident's letter is one of the few moments in which clinical thinking, language and responsibility come together in a single document. Departments that cultivate their letters notice it first in the queries that stop coming, and then in the reputation their letters enjoy among referrers.

Tools are currently shifting the economics of letter writing considerably — what separates text blocks from contextualized generation, we have described in text blocks vs. contextualized generation for physician letters (in German), and what has to happen between draft and signature in AI physician letters: the defensible pipeline (in German). Style, at first, changes little with faster drafts: a text can come into being in thirty seconds and still write past its reader. At aiomics, a style profile is therefore planned that learns a hospital's letter voice from its editing history and stores it as readable, editable German text — planned, not yet shipped.

Five questions for your department's letters

1. Does the first paragraph answer what the continuing physician needs to know — occasion, decision, consequence?
2. Does every medication change come with a reason and, where useful, a planned duration?
3. Do incidental findings and open points stand as tasks, with a responsible party and a time horizon?
4. Would a reader outside the hospital understand every abbreviation?
5. How much of the letter does the recipient actually need — and how much of that is on the first page?

An afternoon with ten randomly drawn letters from your own department and these five questions is one of the cheapest quality measures there is. If documentation as a craft interests you: we write about it regularly in our weekly briefing Visite (German; English edition Grand Rounds is in preparation), which covers documentation and AI in German healthcare.
