The letter before the appointment
The envelope arrives on a Tuesday morning — a ULHT logo in the corner, your name in a window. You open it expecting clarity: when, where, what to bring. What you often find instead is a letter addressed to your GP, with you copied in as an afterthought, dense with clinic codes and consultant names, the actual appointment time somewhere in the third paragraph.
For patients across Grantham and the wider Lincolnshire geography that United Lincolnshire Hospitals NHS Trust serves — Grantham, Boston, Lincoln, Louth — this is a shared experience. The letter is the first contact. There is no nurse, no receptionist, no clinician on the other end: just a document, and whatever sense you can make of it.
That moment of comprehension — or confusion — is not an administrative footnote. The design of that letter, its layout, its language, its tone, already determines whether you attend, whether you prepare, whether you disengage entirely. The appointment letter, it turns out, is already doing clinical work before any clinician is involved.
What the ULHT Patient Panel set out to fix
Since September 2020, the ULHT Patient Panel — volunteers drawn from across Lincolnshire, including the communities served by Grantham District Hospital — has worked on outpatient letter redesign as one of its headline projects. The panel's approach is straightforward: take a real letter, read it as a patient would, and mark where it fails.
The resulting changes follow a clear logic. Date, time, and location move to the very top of the letter — not because this is aesthetically tidy, but because a patient who cannot immediately find when and where to go has already encountered the first failure. Clinic codes and internal reference numbers that carry meaning for hospital systems and nothing for the person holding the envelope are stripped out. These are not formatting tweaks; they are the removal of obstacles that served only the sender.
One of the more significant additions reflects how outpatient care has changed since 2020: every letter now states explicitly whether the appointment is face-to-face, telephone, or video. Before that label was included, patients could arrive in person for what was scheduled as a phone call, or wait at home for a call that required their physical presence. Generic switchboard numbers — which could mean a queue of twenty minutes to reach the wrong department — are replaced with direct lines and recommended times to call.
Alongside the printed letter, ULHT has introduced digital letters via a patient portal. That parallel channel signals something about how the trust frames the problem: this is not a matter of making correspondence look friendlier. It is about removing the conditions under which patients lose access to their own appointment information — whether through a lost envelope, an unread letter, or a format that does not suit them.
The panel was recognised as a runner-up in the Patient Experience Network National Awards 2022, in the 'Engaging and Championing the Public' category.
The clinical cost of a confusing letter
Seven point six per cent sounds like a rounding error. In outpatient NHS services, it represents 7.84 million missed appointments in 2021/22 alone — roughly 650,000 wasted slots every month. NHS England's own guidance on 'did not attends' (DNAs) puts the per-appointment cost at approximately £120, producing a system-wide annual bill close to £1 billion.
For a trust serving rural and semi-rural Lincolnshire, the arithmetic carries an additional weight. Patients travelling to Grantham from surrounding villages face real transport costs and logistical effort. An appointment missed because a letter's date was buried in the third paragraph, or because a telephone consultation looked like an in-person one, is not easily recovered. The patient re-enters a referral queue; diagnosis is delayed; the clinical problem that prompted the original appointment does not pause while the paperwork catches up.
NHS England identifies communication improvements — clearer letters, accurate contact details, explicit modality labelling — as a fast, high-impact intervention that providers can implement within weeks, placing them on the same operational priority tier as capacity or pathway changes. That is not a claim about letter design solving the DNA problem on its own: factors such as transport, health anxiety, and competing caring responsibilities all contribute. But letter quality is distinctive in one respect: it is the one lever a trust can pull without capital investment, waiting for procurement, or system-wide reorganisation. In that sense, a redesigned letter is among the cheapest clinical improvements available.
Typography and tone as clinical decisions
Until 2018, the standard NHS outpatient letter was addressed to the patient's GP. The patient received a copy. Five million such letters went out every month — and the practical consequence of that model was that some patients had to book a separate GP appointment simply to have their own correspondence explained to them. The letter, far from bridging the distance between a diagnosis and the person living with it, was itself a barrier to care.
The Academy of Medical Royal Colleges' 'Please write to me' guidance, published in September 2018 and endorsed by every royal college, reversed that default. The mandated principles are precise: plain English, active voice, first-person address ('I'/'you' rather than 'the patient'), no Latin abbreviations (so 'twice daily', not 'bd'), no acronyms, and strict avoidance of clinical vocabulary that carries different meanings for professionals and patients — 'chronic', for instance, signals permanence to a clinician but severity to most readers.
Typography is held to equally specific standards. Frutiger has been the NHS's primary typeface since 1999 — chosen not for its brand associations but because it was designed for legibility at small sizes and at distance, a quality relevant to patients with age-related vision loss or low literacy. Arial is the secondary option for Word-based documents. NHS England secured a perpetual Frutiger licence for all English NHS organisations in December 2024. Body text runs at a minimum of 12–14pt; large print requests are met at 16pt or above; text is left-aligned, unitalicised, and set with generous line spacing. These are accessibility specifications, not aesthetic choices.
The final design variable is tone, and it is perhaps the least intuitive. Research into appointment nudge communications found that patients actively rejected messages framing missed appointments around the cost burden to the NHS or the inconvenience of rescheduling. What changed behaviour was a different register entirely: altruistic framing — 'helping others get care' — and a simple expression of personal concern for the patient. The information architecture of a letter can be correct and the letter can still fail if its emotional pitch is wrong.
Lay confusion as a design instrument
'I have no NHS background so when I come across medical terms that I do not understand I speak up.' That sentence, from a patient representative at Shrewsbury and Telford Hospital NHS Trust (SaTH) in July 2024, describes something more precise than patient involvement. It describes the deliberate use of incomprehension as a quality instrument.
At SaTH, that mechanism produced a concrete result: patient representatives working alongside staff reduced approximately 7,000 different appointment letter versions to 150 standardised ones. The rep's ignorance of clinical language was not a limitation to be managed — it was the point. Clinical authors are fluent in the vocabulary they use every day; they have lost the ability to see it as opaque. A lay reviewer cannot make that mistake.
The ULHT Patient Panel operates on the same logic. Volunteers drawn from across Lincolnshire — including from the communities Grantham District Hospital serves — are not recruited for clinical knowledge. They are recruited, in effect, because they lack it. When a panel member stumbles on a phrase, that stumble is diagnostic: it marks a place where the letter will fail a real patient.
This is not the same as running a post-hoc patient satisfaction survey. The co-design model inserts lay confusion at the drafting stage, before the letter is finalised, when it can still change the text. The correction costs almost nothing; the blind spot it corrects — the one that trained authors cannot see in their own writing — is systematic and persistent.
Neither ULHT nor SaTH has yet published before-and-after data on DNA rates or patient comprehension scores linked to the redesigned letters. The evidence base at trust level remains qualitative. But the mechanism itself is well-founded: the people most likely to misread a letter are the only reliable judges of whether it can be read.
What design-as-care means for Grantham patients
For a patient in Ancaster, Colsterworth, or Long Bennington — villages within the South Kesteven geography that ULHT serves — a missed outpatient appointment at Grantham is not easily absorbed. The next slot may be weeks away, the journey to rearrange it real. Letter clarity is not a nicety in that context; it is the margin between engaging with a diagnosis and sliding back into a queue.
What the redesign delivered, for someone opening that envelope now, is a single structural change with outsized practical effect: date, time, and location sit at the top — not after the clinic code and the consultant's secretary's name. For a patient who opens the letter quickly between shifts, or who struggles with dense text, that one decision is the appointment.
The work is ongoing rather than complete. Letters that still confuse can be raised with PALS or directly with the Patient Panel, which continues to recruit volunteers from across Lincolnshire, including Grantham itself. The panel's existence is a structural acknowledgement that patients, not clinicians, are the reliable test of whether a communication works.
The standard the panel applies — can a Grantham volunteer with no clinical background find the time and place within ten seconds? — is not a lower bar. For a patient boarding an early bus from Colsterworth to make a 9am outpatient slot, it is the right one.
