Patient Script
For the friend playing the patient role
Character Overview: You are Esme Haddad, a 31 year old copywriter at a marketing agency, taking this video call on your laptop at your kitchen table. You live with your girlfriend Jodie, a physiotherapist, in a rented flat. You are bright and organised and hate not knowing where you stand. Today you sound tired and a little wound up, and talk quickly when anxious.
Your dad, Karim, is 55. He ran a Lebanese bakery for twenty years and had to hand it over when his kidneys failed. He never had insurance and money at home has been tight since. His consultant told him his children should think about being checked, and your mum passed this on to you and your brother.
You are part way through an online application for life insurance and critical illness cover of about £150,000. You have not sent it. You have had five or six headaches this month; otherwise you feel well. You call your dad's condition "Dad's kidney condition" or "the cysts". You do not volunteer your beliefs, fears or the dilemma about the form until the doctor asks.
Opening Sentence: "Hi, thanks for seeing me. So, my dad's just started dialysis for his kidney condition, and his consultant told him me and my brother should think about getting checked. I honestly don't know whether I should, or what it even involves. And I've had a few headaches lately, which isn't helping my nerves."
History if Asked (Data Gathering Phase)
- ●Her dad (if asked how he found out and how he is now): "He was thirty six. He got a kick in the side playing five a side, then there was blood in his wee, and the scan showed both kidneys full of cysts. He started dialysis five weeks ago, and they're testing whether he can go on the transplant list. I don't think he's had a gene test."
- ●How it has been seeing him (if asked how she is coping): Her voice catches. "I sat with him at the first session. He looked so small in that big chair, and he kept telling me to go home."
- ●Wider family (if asked about other relatives): "Dad's mum, my teta, died at sixty three. Everyone says it was her kidneys, but nobody had a name for it. Dad's sister, Auntie Rima, had a scan in her forties and she's clear. My brother Sami's twenty nine. He says he doesn't want to know, because what's the point if they can't stop it. Mum's side is fine."
- ●Bleeds on the brain or sudden deaths (if asked): "No, not that I've heard of."
- ●The headaches: "About five or six in the last month. A tight band across my forehead, both sides, late afternoon when I've been on my laptop all day, building slowly. Maybe five out of ten at worst. Two paracetamol takes the edge off, or it's gone once I've slept. Paracetamol on maybe four days this month."
- ●What has changed (if asked about sleep, stress, caffeine or screens): "Everything, really. I'm not sleeping, I lie there thinking about Dad. I'm catching up on work late at night, skipping lunch and on about five coffees a day, double what I used to have. And we've got a big campaign next week."
- ●The insurance application (if asked): "Life insurance and critical illness together, online. I ticked yes to a parent with kidney disease. The next page asks if I'm waiting for any tests or results, and I stopped. I haven't sent it."
- ●Why she wants cover (if asked): "Because of Dad. He never had anything. When he had to stop work the money just stopped, and Mum's been holding it all together. I don't want to end up like that."
Ideas, Concerns, Expectations
Gating note: Esme does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks is going on, what is worrying her, or what she was hoping for.
- ●Ideas: She half believes the condition mostly passes down to the men in a family, because it went from her grandmother to her dad and not her auntie. She also thinks the headaches might be her blood pressure going up. If asked: "I sort of thought it was more of a men's thing? It went to Dad and not Auntie Rima. And I read that blood pressure's usually the first thing to go, so I wondered if that's the headaches."
- ●Concerns: She fears the headaches could be a bleed on the brain, and that if she is checked and it shows something nobody will insure her and she will end up like her dad. If asked: "I read that bleeds on the brain are linked to it, and that's properly scared me. And if I get checked and it's bad news, I'll never get covered, and I'll be exactly where Dad is."
- ●Expectations: She wants to be told whether to get checked and whether to send the form first. If asked: "I suppose I want you to just tell me what to do. Do I get scanned, or do I send the form off first?"
If Asked: Medical History and Medications
Gating note: Esme answers each of these plainly when the doctor asks about it.
- ●Health and medicines: "I'm hardly ever ill. Just paracetamol, no ibuprofen, I wasn't sure it was okay with Dad's thing. I've got the copper coil. No allergies. Not pregnant, and children are a few years off."
- ●Blood pressure and kidney tests: "I think the last time anyone checked my blood pressure was when I joined the practice, about four years ago. I haven't got a machine. I've never had my kidneys tested, as far as I know."
Social History and Lifestyle Impact
Gating note: Esme mentions this naturally as the conversation turns to her work, her family and how she has been coping.
- ●Work and home: In the office Mondays and Thursdays. "Work's the only thing that feels normal at the moment."
- ●Lifestyle and mood: "I'm shattered, and Jodie says I'm snappy. I'm a bit teary at night, but I'm not depressed." Never smoked, a couple of glasses of wine at weekends, no drugs.
If Asked: Associated Symptoms
Gating note: Esme answers these briefly, only when asked.
- ●If asked about a sudden or explosive headache, waking with it, worse on coughing, straining or lying down, being sick, light or noise bothering her, vision changes, weakness, numbness, speech problems, fever, a stiff neck or a head injury: "No, nothing like that. They creep up on me."
- ●If asked about blood in her urine, pain in her sides or back, passing more urine, chest pain, palpitations, breathlessness or nosebleeds: "No, never." One water infection at nineteen, nothing since.
Responses to Management (The Negotiation Phase)
- ●If the doctor explains that each child has a 1 in 2 chance, son or daughter, that it does not skip generations, or that if she is clear she cannot pass it on:
- ●Reaction: Surprised. "So it's not a men's thing at all? Then how come Auntie Rima got away with it?" She understands quickly if it is compared to a coin toss. Once her chance is explained she asks once: "Dad was fifty five when he started on the machine. If I have got it, is that roughly my timeline too?"
- ●If the doctor explains the headaches, or suggests a blood pressure check, kidney tests or painkillers:
- ●Reaction: Relieved but checking. "So it's not my blood pressure? How would you even know without checking it?" If told high blood pressure usually causes no symptoms: "So I could have it and feel fine? That's worse, in a way." If normal results are mentioned: "If those come back normal, does that mean I haven't got it?" If ibuprofen is suggested: "Is that okay for my kidneys?"
- ●If the doctor discusses a scan, waiting, referral to the genetics or kidney team, or a gene test:
- ●Reaction: Hesitant. "Today? I haven't even decided if I want to know yet. What happens with the insurance if it shows something?" If told she need not decide today: "So it's not dangerous to wait?" If told a clear scan may not rule it out: "So I might still have it?" Once the options are set out she asks: "If you were me, what would you do?"
- ●If the doctor explains how insurers treat family history, genetic tests and scans, or suggests leaving her dad's condition off the form:
- ●Reaction: Deflated, then checking. "So I'm already marked down because of Dad, whatever I do?" If told she could arrange cover first and decide about screening afterwards: "And that's allowed? I'm not cheating anyone?" If told to leave anything off: "Is that allowed, though?"
- ●Once the doctor suggests any check, test or scan, if she has not already asked, she asks once about her record:
- ●Reaction: Anxious, voice dropping. "Would that go on my record? Could it be kept off, just until the insurance is sorted?" If told the record has to be accurate: embarrassed. "No, of course. Sorry, I shouldn't have asked. I'm just panicking about ending up like Dad." She settles if the doctor is kind and explains what she can control.
- ●If the doctor gives vague safety netting, or raises her brother, giving a kidney to her dad, or asks her to examine herself on camera:
- ●Reaction: On "come back if it gets worse": "Worse how? I don't want to ring 999 over a normal headache, but I don't want to sit at home with a bleed either. What would a bad one actually feel like?" Once a thunderclap headache is described: "So like being hit round the head out of nowhere. Not the slow ones I'm getting." She declines to examine herself: "I wouldn't know what I was feeling for. I can come in if you need to check anything."

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Esme is a well 31 year old whose father has autosomal dominant polycystic kidney disease (ADPKD) and has just started haemodialysis. She has a 1 in 2 chance of having inherited it. Three things arrive together: whether to be screened, what screening would mean for the life and critical illness cover she is applying for, and a month of headaches she fears are the condition starting.
- ●Model plan: take a full family and headache history; explain the 1 in 2 chance and correct the belief that daughters are spared; diagnose tension type headache and explain that blood pressure must be measured, not inferred; arrange a blood pressure check and offer kidney function and urine tests; set out screening honestly; give accurate insurance information and an accurate record; safety net for a thunderclap headache; agree follow up.
- ●Acceptable alternatives: a practice requested ultrasound after discussing the implications, referral to clinical genetics or the renal team, or waiting and revisiting, provided blood pressure is checked. The headaches need assessing today, her blood pressure needs checking whatever she decides, and screening is her decision.
ADPKD and Its Inheritance
- ●The KDIGO (Kidney Disease: Improving Global Outcomes) 2025 ADPKD guideline puts the prevalence of disease causing variants at about 1 in 1,000. Cysts enlarge over decades; kidney function usually stays normal until middle age. Median age at kidney failure is about 54 to 58 for PKD1 and 74 to 80 for PKD2, varying even within a family.
- ●High blood pressure is the commonest and earliest feature, usually diagnosed before 30 while kidney function is normal. Other features are haematuria, stones, cyst infection, flank pain, liver cysts and, more often than in the general population, intracranial aneurysms.
- ●Each child of an affected parent has a 1 in 2 chance, independently and regardless of sex. It does not skip generations; someone who has not inherited it cannot pass it on. Her grandmother passing it to her father but not her aunt was chance, and her aunt's clear scan in her forties is reliable. Her brother's status does not change her own.
Assessing the Headaches
- ●Her headaches fit tension type headache in NICE CG150: bilateral, pressing, mild to moderate, no nausea or aura, on fewer than 15 days a month. CG150 lists features needing evaluation, including onset reaching maximum within 5 minutes, new neurological deficit, headache triggered by coughing or straining, postural change, fever and head injury. She has none.
- ●High blood pressure usually causes no symptoms unless very high, so the headaches neither confirm nor exclude it. CG150 advises against neuroimaging solely for reassurance. Aneurysm screening only arises if she is found to have ADPKD.
- ●CG150 suggests aspirin, paracetamol or an NSAID for acute treatment and advises against opioids. While her kidney status is unknown, paracetamol is a sensible first choice; KDIGO 2025 makes it first line in ADPKD and discourages NSAIDs for ongoing pain, though short term use for acute pain with stable kidney function is accepted. Medication overuse headache is described at 15 or more days a month for 3 months.
Blood Pressure and Kidney Checks
- ●KDIGO 2025 (Practice Point 6.1.4) says early diagnosis and adequate treatment of high blood pressure is indicated in people at risk of ADPKD. It does not depend on her screening decision or insurance timetable. Her last reading was four years ago, so arrange one soon, with the nurse or on a validated home monitor.
- ●NICE NG203 (1.1.21) says to offer eGFR and urine albumin to creatinine ratio to adults with a family history of hereditary kidney disease. Normal results are expected at 31 even with ADPKD.
- ●Under NICE NG136, a clinic reading of 140/90 mmHg or more is confirmed with ambulatory or home monitoring, and under 40 specialist evaluation of secondary causes is considered. If she declines screening, agree regular rechecks; yearly is reasonable, as no national interval exists.
Screening: Benefits, Downsides and What a Result Means
- ●KDIGO 2025 puts the person's values at the centre and advises counselling before and after imaging or genetic screening. NICE NG203 (1.2.6) says to advise adults with a family history of hereditary kidney disease about the implications of an abnormal result before a renal ultrasound is arranged.
- ●Benefits: a definite answer, closer blood pressure control, monitoring, tolvaptan if rapidly progressing (NICE TA358), pregnancy planning, relief if negative and clarity before any living donation. Downsides: the weight of a lifelong diagnosis while well, insurance and employment implications, and inconclusive or falsely reassuring results. Screening now and waiting are both defensible.
- ●Ultrasound is first line (KDIGO 1.3.1). Between 15 and 39, three or more cysts confirms ADPKD with a family history. Excluding it is harder: at 15 to 29, no cysts has a negative predictive value of about 91% when the gene is unknown (84% in PKD2 families), about 98% at 30 to 39, and from 40 fewer than two cysts effectively excludes it. A clear scan at 31 is reassuring but not conclusive; if she wants more certainty, the options are MRI or genetic testing.
- ●Predictive genetic testing of a relative (National Genomic Test Directory R242) requires the family's variant to have been found in an affected relative first. Her father has never been tested, so a gene test is a question for genetics or the renal team.
Insurance and an Honest Record
- ●The Code on Genetic Testing and Insurance (Government and the Association of British Insurers, updated March 2026) covers life, critical illness and income protection cover. Insurers will not require a predictive or diagnostic genetic test, and will not ask for or use predictive results, except Huntington's disease for life cover above £500,000.
- ●The Code does not apply to scans or blood and urine tests, and insurers may ask about family history and request GP reports. Her father's diagnosis must be declared if the form asks and may already affect terms; a scan showing cysts would be disclosable if a question covers it.
- ●Under the Consumer Insurance (Disclosure and Representations) Act 2012 she must take reasonable care not to misrepresent, so truthful answers protect her. Arranging cover first and deciding about screening later is lawful and is her decision; the doctor ensures she has accurate facts.
- ●The GMC expects clear, accurate records, nothing false or misleading and no deliberate omission of relevant information. A record leaving out a test, result or today's consultation at her request would not meet that principle, and the same applies to insurer reports. Explain it kindly. Under the Access to Medical Reports Act 1988 she can see any report before it is sent, ask for corrections and withhold consent.
If She Has Inherited It: What Changes
- ●KDIGO 2025 recommends a home blood pressure target of 110/75 mmHg or lower, if tolerated, at ages 18 to 49 with chronic kidney disease stage G1 to G2 and blood pressure above 130/85, with an ACE inhibitor or ARB first line.
- ●Aneurysm screening, usually by magnetic resonance angiography, is recommended where there is a family history of aneurysm, subarachnoid haemorrhage or sudden death; Esme has none. Pregnancy carries higher risk of pre eclampsia, and low dose aspirin (75 to 150 mg daily) is advised from week 12 to 36. Preimplantation genetic testing is an option.
Safety Netting and Follow Up
- ●Thunderclap headache: sudden, severe, worst within seconds to minutes, often the worst ever, sometimes with vomiting, neck stiffness, collapse, a fit or confusion. Call 999. Same day advice if headaches become frequent or severe, wake her, worsen on coughing, straining or lying down, or come with fever, repeated vomiting, visual change or weakness. Contact the practice for blood in her urine or new pain in her side or back.
- ●Review blood pressure and results, then revisit the screening decision with written information.
Common Mistakes in This Station
- ●Agreeing that it is "more of a men's thing", or not correcting her belief that daughters are less at risk.
- ●Arranging a scan without discussing what an abnormal result would mean, including for insurance.
- ●Telling her a clear scan at 31 means she has not inherited it, or that screening is unavailable or pointless.
- ●Treating the headaches as proof of high blood pressure, or ordering brain imaging for reassurance.
- ●Forgetting her blood pressure, or tying the check to the insurance timetable.
- ●Stating that insurers cannot use any of this information, or advising her to leave her father's condition off the form.
- ●Agreeing to keep anything off her record, or lecturing her for asking.
- ●Deciding for her, or refusing to engage when she asks what the doctor would do.
- ●Safety netting with "come back if it gets worse" instead of describing a thunderclap headache.
