Voice in a clinical setting is a governance matter
Tone of voice is normally treated as a branding preference, and in most sectors it is. In a clinical setting two of the criteria here are closer to governance than to style.
The first is how the body is described. Copy that characterises ordinary features as flaws, or that describes a normal appearance as something to be corrected, is doing something more than choosing a register. It is constructing a concern in order to address it. This is common in the sector and it is worth scoring explicitly, because it tends to enter copy through imitation rather than through decision.
The second is urgency. Manufactured urgency in copy about elective procedures operates on the same reflection period that the consent process is meant to protect, which is why it appears as a failure in three instruments in this library.
Voice also interacts with what is published as fact, which the claim substantiation checklist scores: emphatic writing and unsupportable claims tend to arrive together. The other criteria are ordinary consistency questions with one practical consequence: a clinic that sounds like several organisations reads as a collection of individuals rather than as a practice, and patients notice the difference without being able to name it.
The final criterion, a documented voice, is what makes any of this survivable. Voice is maintained by a document or by one person, and the person leaves.
How to score this scorecard
Select six pieces written by at least three different people across at least three surfaces: a treatment page, a social caption, an email to a patient, a profile description, a blog post and an appointment reminder. Score by the set rather than by the best example.
For criterion one, read them consecutively and ask whether they came from one organisation. This judgement is reliable when made by somebody who did not write any of them and unreliable when made by an author.
For criterion four, count superlatives. More than one or two across six pieces indicates that emphasis is substituting for specificity.
For criterion five, mark every phrase describing a bodily feature and ask whether it describes or evaluates. "Lines between the brows" describes; "tired, angry-looking frown lines" evaluates and constructs a concern.
For criterion nine, look for the places where risk, cost or unsuitability would naturally arise and see what the writing does at those points. Deflection is usually visible as a change of subject.
For criterion ten, ask to see the document. A shared understanding scores 1.
Common scoring errors
Scoring the best-written piece. Consistency is a property of the set.
Treating superlatives as harmless enthusiasm. They also tend to be unsupportable claims, which the substantiation checklist scores separately.
Missing evaluative language because it is conventional. Much of the sector's standard vocabulary evaluates the body. Convention is not neutrality.
Excluding transactional messages. Appointment reminders and confirmations are read by every patient and are usually written by somebody outside the voice discussion.
Scoring the voice document as existing because a supplier produced brand guidelines. Most guidelines cover visual identity. Criterion ten asks for a written voice with examples.
Writing a voice document that gets used
A voice document that gets used is short. One page, three sections.
First, three adjectives with a sentence each explaining what they mean in practice for this clinic. Second, six paired examples: a sentence written badly and the same sentence written well, drawn from your own material rather than invented. Third, a short list of words and constructions the clinic does not use, which for most clinics should include superlatives, urgency language and evaluative descriptions of the body.
Paired examples do almost all the work. A writer who sees the clinic's own copy rewritten understands the voice in a way that no list of adjectives conveys.
Give the document to everybody who writes anything, including any supplier, before they draft. Retrofitting voice onto finished copy is expensive and produces a compromise.
Then use the communication clarity rubric alongside it, because voice and clarity can pull against each other: a distinctive voice applied to an aftercare instruction is usually a worse aftercare instruction. Where the two conflict in patient-safety material, clarity wins.
