Tense Mixing in Doctors’ Letters: A Section-by-Section Map

Problem: doctors’ letters written in one tense throughout — histories in present, current status in past, plans with no future — confuse readers about what is true now. Answer in brief: map tenses to letter sections: present for current status, past for history, present perfect as the bridge, future for plans and recommendations. Referral and discharge models with 12 tasks below.

Learning outcomes

By the end you will be able to: assign tenses by letter section (presentation, history, status, plans); use present perfect to bridge past events to present relevance; write referral and discharge letters with smooth tense flow; and drill mixing with workbook excerpts and editing practice. All guidance follows the source book, Mastering English Verb Tenses for OET Doctors’ Writing (OET GRA DOC 01 tenses) (Jobin Thomas) — per-tense chapters, mixing-strategies chapter, sample referral/discharge letters and tense workbook, verified by full-structure scan with chapter sampling. Language-learning examples with fictional scenarios only; never clinical guidance.

The section–tense map

Opening/presentation: present simple (“Thank you for seeing Mr X, 62, with exertional chest pain”) — the patient and reason exist now. History/body: past simple for dated events (“He presented in March; angiography showed…”), past continuous for background (“He was taking statins”), past perfect for earlier causes (“…which had been started after his 2021 infarct”). Current status: present simple/continuous (“He remains stable; he is awaiting catheterisation”). Plans/recommendations: future and modal futures (“He will require…; I would be grateful if you could…”). The map is checked per paragraph: each paragraph’s dominant tense must match its section’s job — a history paragraph in present tense is a section error, not a tense slip.

The present-perfect bridge

Present perfect connects past events to present relevance: “His symptoms have improved since commencing…” (past start, present result); “She has been breathless since March” (continuing). Bridge positions: end of history paragraphs (linking to status) and progress statements (“has recovered enough for discharge” vs “recovered” — the perfect claims current fitness, the simple reports a past event). Overuse flattens meaning — reserve perfect for genuine past-to-present links; dated completed events stay simple past (“was admitted on 4 May”, never “has been admitted on 4 May”).

Referral letters: tense in action

Referral flow: present opening (who + why now) → past history (what led here) → perfect bridge (what changed / current relevance) → present status (condition at writing) → future/modal request (what is asked). The request paragraph is the letter’s purpose — tense errors here cost most: “I would be grateful if you could assess…” (polite modal, timeless) with future plans stated plainly (“He will need…”). Keep histories compact; the referee needs trajectory, not biography — select events that motivate the referral.

Discharge letters: tense in action

Discharge flow: past admission and course (“She was admitted with…; she received…”) → perfect bridge to fitness (“She has recovered sufficiently…”) → present status at discharge (“She is afebrile; she mobilises with a frame”) → future/GP actions (“Please review in one week; she will require…”) → red-flag conditionals (“If fever recurs, readmit”). Discharge letters carry handover responsibility — status and plans must be temporally unambiguous. Past-perfect appears for pre-admission causes (“…which had begun three days prior”); scheduled follow-ups take present continuous (“She is seeing physiotherapy on Friday”).

Worked models: mixed letters annotated

Labelling: all letters below are newly written in the book’s sample patterns. The book’s samples are not reproduced. Fictional scenarios; language examples only.

Model 1 — Cardiology referral, tense-flagged (newly written)

“Thank you for seeing Mr Hart, 62, with exertional chest pain (present opening). He presented in March with similar symptoms; angiography at that time showed moderate disease (past history). His symptoms have worsened despite optimised medication (perfect bridge). He remains haemodynamically stable but is limited to 100 metres (present status). I would be grateful if you could assess him for revascularisation; he will require ongoing anti-anginal cover meanwhile (modal request + future plan).” Flags: present → past → perfect → present → modal/future — five moves, smooth flow.

Model 2 — Discharge extract, tense-flagged (newly written)

“Mrs Lane was admitted with community-acquired pneumonia (past). She received intravenous antibiotics for three days, having previously failed oral therapy (past + past-perfect cause). She has recovered sufficiently for discharge (bridge). She is afebrile and mobilising independently (present status). Please review her chest in one week; she is seeing respiratory outpatients in a fortnight (request + scheduled future). If fever or breathlessness recurs, please readmit directly (conditional safety-net).” Note: handover-complete — course, fitness, status, actions, red flags, each temporally exact.

Model 3 — Bridge repair demo (newly written)

Flat: “He was breathless. He is better. Discharge.” Bridged: “He was breathless on admission (past event). He has improved steadily on treatment (bridge with mechanism implied). He is now fit for discharge with community follow-up (present verdict + plan).” Note: the bridge sentence does the clinical reasoning work — improvement linked to treatment, fitness claimed presently.

Model 4 — Editing practice: find the five slips (newly written)

Draft: “Thank you for seeing Mr Fox which has chest pain. He present last week. He is admitted twice before. His symptoms are improved since treatment. He will can attend Friday.” Cures: which→who (relative for people); present→presented (tense); is admitted→has been admitted (perfect for experience-count); are improved→have improved (bridge, not passive state); will can→will be able to/can (modal stacking illegal). Note: five slips, five lesson codes — the workbook method in miniature.

Common errors and corrections

• Single-tense letters: one tense throughout. Correction: section map — five moves.
• Bridgeless histories: past then present with no link. Correction: perfect bridge carrying reasoning.
• Dated perfects: has admitted on 4 May. Correction: dates take simple past.
• Modal stacks: will can/must should. Correction: one modal; ability = be able to.
• Which-for-people: Mr Fox which. Correction: who for people, which for things.
• Biography histories: every event ever. Correction: trajectory only — referee needs motive.

Independent task and self-check

Task (newly written): label two letters fully by section-tense; write one referral and one discharge with flagged moves; edit monthly with codes.

Self-check: does each paragraph match its section tense? Are bridges present with reasoning? Are requests modal-clean? Are histories compact? Four yeses = mixing mastered.

Study sequence with the book

1. Read per-tense chapters; fix forms with drills.
2. Study the mixing-strategies chapter; memorise the section map.
3. Analyse the sample referral/discharge letters move by move.
4. Work the tense workbook excerpts with labels.
5. Write full practice letters with flagged moves.
6. Edit with codes; final review on mixed scenarios.

FAQs

How many tenses per letter? Typically 4–5 across sections — map-driven, not counted. Smooth flow is the test.

Perfect in every letter? Nearly — histories need bridges. But dated events stay simple past.

Referral vs discharge tense emphasis? Referrals lean present+future (status and request); discharges lean past+bridge (course and fitness).

What about nursing letters? Same map, different content — the section-tense logic is profession-independent.

How does this fit the dentistry volumes? Those drill tense/voice contrasts and polite plans; this volume maps mixing across full doctors’ letters. Contrasts first, maps second.
