Patient Script
For the friend playing the patient role
Character Overview: You are Paul, a 52-year-old regional sales manager. You spend hours sitting in your car and often rely on service station food. You are extremely anxious today. When the receptionist told you the scan showed a "liver problem," your mind immediately went to the worst-case scenario. Your father was a heavy alcoholic who died a horrible, drawn-out death from liver cirrhosis when he was 58. You only drink moderately (a few beers on the weekend), so you are terrified and confused as to why your liver is failing. You are secretly convinced you have cirrhosis and are going to die just like him. You feel a deep sense of shame about the word "liver disease." You will not volunteer the story about your father or your fear of cirrhosis unless the doctor asks what you are worried about, explores your family history, or notices how tense you are.
Consultation Flow & Responses:
- ●
The Opening
- ●
If the doctor asks an open question: "Morning, Doc. The receptionist said my ultrasound results were back and there's a problem with my liver. I just need you to tell me straight—how bad is it?"
- ●
Data Gathering (The Layers)
- ●
Layer 1: Alcohol & Lifestyle (The Differential Screen):
- ●
If asked about alcohol: "I drink a bit on the weekends. Maybe 4 or 5 pints of beer while watching the football. I don't touch spirits and I never drink during the week." (Testing the doctor's ability to calculate units and rule out Alcoholic Liver Disease).
- ●
If asked about diet/exercise: "My diet is pretty rubbish, to be honest. I'm on the road a lot for sales, so it's mostly sandwiches, crisps, and fast food. I don't really exercise besides walking the dog."
- ●
Layer 2: Systemic Symptoms (Ruling out advanced disease):
- ●
"I feel fine physically. Maybe a bit more tired lately, but I put that down to work. My eyes aren't yellow, my tummy isn't swollen, and my toilet habits are normal."
- ●
Layer 3: ICE & The Core Revelation (The Hidden Trauma) - ONLY REVEAL IF ASKED:
- ●
If the doctor asks: "What are you worried this might mean?" or "Does liver disease run in your family?"
- ●
Reaction (The Reveal): You lean forward, looking incredibly stressed. "My dad died of cirrhosis when he was 58. It was a horrible way to go. He was a heavy drinker, but I'm not! So when they said 'liver problem', I just assumed... is my liver scarring? Am I getting cirrhosis? I've got kids, Doctor. I can't go out like my dad did."
- ●
Layer 4: Readiness to Change:
- ●
If the doctor explains it is reversible: "Reversible? You mean it's not permanently scarred yet? If you tell me what to do, I'll do it. I'll throw out all the junk food today. I just need to know I'm not dying."
ICE — Ideas, Concerns, Expectations
Do not volunteer any of this unprompted. These responses surface only when the candidate directly explores the patient's perspective.
- ●
Ideas: You assume the "liver problem" means your liver is being damaged the same way your father's was — by disease that scars and destroys the organ. You don't really understand how fat in the liver works or that it can be caused by diet rather than alcohol. You think liver disease is liver disease, and it all ends the same way.
- ●
Concerns: Your overriding fear is that you are developing cirrhosis like your father and will die the same drawn-out death he did. Underneath that, you are terrified of leaving your children without a father. There is also a layer of shame — you associate liver disease with heavy drinking and worry others will assume you have a problem with alcohol, even though you don't.
- ●
Expectations: You want the doctor to be straight with you — tell you honestly how serious this is and whether you are going to be okay. You want a clear plan: tests that can prove you don't have cirrhosis, and practical steps you can take to fix this. You need reassurance, but only reassurance grounded in evidence — vague platitudes will not settle you.
If Asked — Medical History and Medications
The patient does not raise these unprompted. Respond naturally if directly asked.
- ●
If asked about blood pressure / hypertension: "Yeah, they picked that up a couple of years ago on a check-up. It's been fine on the tablets as far as I know — they've never said it's a problem."
- ●
If asked about Ramipril or current medications: "I take one tablet in the morning for my blood pressure — Ramipril, I think it's called. I've been on it a couple of years. No problems with it."
- ●
If asked about weight / BMI / obesity: "I know I'm overweight. The nurse mentioned it at my last check-up. I've put on a couple of stone over the last few years — the job doesn't help, sitting in the car all day and eating rubbish. I've tried cutting back but it never sticks for long."
- ●
If asked about the recent blood tests: "I had those done a couple of weeks ago — the doctor wanted to check my liver after something came back a bit off on the routine bloods. I don't really know what the numbers mean, just that something was raised."
- ●
If asked about the ultrasound experience: "It was fine, painless. But when the receptionist rang to book this follow-up and said there was a liver problem, I barely slept that night. I've been dreading this appointment."
- ●
If asked about allergies: "No, no allergies to anything that I know of."
Social History and Lifestyle Impact
Integrate naturally into conversation — do not deliver as a monologue.
- ●
Occupation and daily life: You are a regional sales manager covering the Midlands. You drive 200-odd miles on a typical day visiting clients, which means long hours in the car, irregular meals, and very little physical activity. Your wife works part-time and you have two children — a daughter in sixth form and a son at university. You are the main breadwinner.
- ●
Lifestyle impact of the condition: The anxiety since the receptionist's phone call has been overwhelming. You couldn't concentrate on your client meetings all week — you kept zoning out thinking about your dad at the end. You haven't told your wife about the scan results yet because you didn't want to worry her until you knew what you were dealing with. You barely ate yesterday because your stomach was in knots. The word "liver" carries enormous emotional weight for your family, and hearing it applied to you has shaken you badly.
If Asked — Associated Symptoms
Respond only when directly asked. Keep answers brief and natural.
- ●
If asked about abdominal pain or discomfort: "No, not really. Maybe a bit of bloating after a big meal, but nothing I'd call pain."
- ●
If asked about nausea or vomiting: "No, nothing like that."
- ●
If asked about itching (pruritus): "No, I'm not itchy anywhere."
- ●
If asked about bruising or bleeding easily: "No, I don't think I bruise more than normal."
- ●
If asked about changes in urine colour: "No, it's normal — nothing dark or unusual."
- ●
If asked about changes in stool colour: "No, normal colour, normal consistency."
- ●
If asked about ankle swelling (oedema): "No, my ankles are fine."
- ●
If asked about confusion or memory problems (hepatic encephalopathy): "No, my head's clear — well, apart from being worried sick about all this."
- ●
If asked about loss of appetite: "Not normally, no. I've not eaten much the last couple of days, but that's just the nerves about this appointment."
- ●
If asked about joint pain: "No, nothing like that."
- ●
If asked about excessive thirst or urination (diabetes screen): "No, I drink normal amounts and I'm not running to the loo all the time."
- ●
If asked about chest pain or palpitations: "No, nothing wrong with my chest."
- ●
If asked about shortness of breath: "I get a bit puffed going up stairs, but I put that down to the weight. Nothing that worries me."
- ●
If asked about snoring or sleep apnoea: "My wife says I snore like a freight train, but I've never been tested for anything. I do feel knackered most mornings, to be fair."
- ●
If asked about skin changes (spider naevi, palmar erythema): "No, I haven't noticed anything odd on my skin."
- ●
If asked about sexual function or gynaecomastia: "Everything's fine in that department, thanks."
- ●
If asked about recent travel: "No, I haven't been abroad recently."
- ●
If asked about recreational drug use: "No, never touched anything like that."
- ●
If asked about over-the-counter medications or supplements: "No, just the Ramipril. I don't take anything else."
- ●
If asked about family history of diabetes or heart disease: "My mum had type 2 diabetes — she was diagnosed in her sixties. My dad... well, he had the liver problems I mentioned. I don't know about heart disease specifically."
Negotiation & Collaborative Management Plan
- ●
If the Doctor is dismissive ("It's just a bit of fat, nothing to worry about"):
- ●
Reaction: Confused and anxious. "Just a bit of fat? But my dad's liver failed! Doesn't fat destroy the liver eventually? Aren't you going to do any more tests?" (Doctor must explain risk stratification).
- ●
If the Doctor tells you to "lose weight and stop drinking" without explaining the mechanism:
- ●
Reaction: Defensive. "I told you, I barely drink compared to most people! And I'm trying to lose weight, it's just hard on the road. It feels like you're blaming me."
- ●
If the Doctor explains MASLD/NAFLD and the FIB-4 score/blood test:
- ●
Reaction: "So it's the food, not the alcohol, causing this? And you can do a blood test to prove it hasn't turned into cirrhosis yet? Yes, please do that test. I need peace of mind."
- ●
If the Doctor mentions checking for diabetes and cholesterol:
- ●
Reaction: "That makes sense. If my body is storing fat in my liver, my heart probably isn't doing too great either. Let's check it all."
Safety Netting / Follow-up
- ●If the Doctor sets a plan to review the new bloods and weight in 4 weeks:
- ●Reaction: "Okay. I'll get the bloods done this week. I'm going to download a calorie app when I get to the car. Thank you for explaining it to me properly."

Domain 2: Clinical Management and Medical Complexity
Domain 3: Relating to Others
Clinical Learning Points
NAFLD vs. MASLD — Understanding the Diagnosis
- ●The condition is now formally termed Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), replacing the older term Non-Alcoholic Fatty Liver Disease (NAFLD). The nomenclature change is deliberate: it removes the stigmatising "alcoholic" framing and accurately identifies the underlying driver as metabolic dysfunction — specifically insulin resistance and central adiposity.
- ●MASLD is defined by hepatic steatosis (fat in >5% of hepatocytes on imaging or histology) in the presence of at least one cardiometabolic risk factor, with no evidence that alcohol or another cause is responsible.
- ●Pathophysiology: Excess caloric intake leads to hepatic triglyceride accumulation (steatosis). Sustained oxidative stress and inflammation cause hepatocyte injury (steatohepatitis / MASH), activating hepatic stellate cells to deposit collagen — progressing through fibrosis stages to cirrhosis. Not all patients with steatosis progress; risk stratification identifies those at meaningful risk.
Differentiating MASLD from Alcoholic Liver Disease
- ●The clinical distinction between MASLD and Alcoholic Liver Disease (ALD) requires precise alcohol quantification — not simply asking "do you drink?".
- ●4–5 pints of regular-strength beer (~5 units per pint) consumed over a weekend equates to approximately 20–25 units per week — above the NHS recommended limit of 14 units per week. However, this level of consumption alone is insufficient to cause the pattern of hepatic steatosis seen here; the metabolic context (obesity, sedentary lifestyle, poor diet) is the dominant aetiological driver.
- ●MASLD is distinguished from ALD by the predominance of metabolic risk factors, the pattern of LFT derangement (isolated mild ALT elevation is characteristic), and the ultrasound findings considered alongside a careful alcohol history.
- ●The absence of jaundice, coagulopathy, splenomegaly, ascites, and symptoms of portal hypertension in this patient argues strongly against established cirrhosis of any aetiology.
Risk Stratification — The FIB-4 Score
- ●An abdominal ultrasound diagnoses steatosis reliably but is insensitive for detecting early fibrosis. A reassuring scan does not exclude significant scarring.
- ●Per NICE CKS NAFLD, all patients with incidentally identified hepatic steatosis must be risk-stratified for advanced fibrosis before a primary care management pathway is confirmed. Repeat ultrasound is not the appropriate next step.
- ●First-line tool: FIB-4 Index — calculated from age, AST, ALT, and platelet count (all available from Paul's recent bloods). Can be calculated directly in most GP clinical systems or via online calculators.
- ●Low risk (FIB-4 <1.30; or <2.0 in patients aged >65): Manage in primary care; reassess FIB-4 in 3–5 years.
- ●Indeterminate (1.30–2.67): Refer for an ELF (Enhanced Liver Fibrosis) test or FibroScan (transient elastography) via hepatology.
- ●High risk (FIB-4 >2.67): Refer to hepatology for formal assessment and biopsy consideration.
- ●Paul's FIB-4 (age 52, AST 38, ALT 65, platelets 210) is approximately 0.87 — well within the low-risk range, supporting primary care management and providing objective grounds for reassurance.
The Cardiovascular Priority
- ●The leading cause of death in patients with MASLD is cardiovascular disease, not liver failure. Every patient with MASLD must be assessed and actively managed as a cardiovascular risk case.
- ●Arrange: HbA1c (screen for T2DM — MASLD is an independent risk factor, and Paul has maternal T2DM and a BMI of 31), fasting lipid profile, and a formal QRISK3 assessment.
- ●Paul's hypertension requires review in this context: blood pressure should be optimised as a component of metabolic syndrome management, not treated as a background problem.
- ●Statins and the liver: Statins are not contraindicated in MASLD, even with a mildly elevated ALT. NICE and hepatology guidelines confirm statins are safe up to ALT 3x the upper limit of normal. They reduce cardiovascular mortality and may improve liver histology. Withholding statins where QRISK3 indicates benefit is a clinical error.
Obstructive Sleep Apnoea — A Modifiable Driver
- ●Obstructive sleep apnoea (OSA) is independently associated with MASLD severity and is a recognised contributor to disease progression, likely via intermittent hypoxia and worsening insulin resistance.
- ●An obese male with heavy snoring and unrefreshed sleep has a high pre-test probability of OSA. This should not be overlooked in the context of MASLD.
- ●Assess with an Epworth Sleepiness Scale and, if indicated, refer to a sleep clinic for home oximetry or formal polysomnography. Treating OSA may itself contribute to MASLD improvement.
Lifestyle as First-Line Treatment
- ●MASLD is highly reversible at the steatosis stage — communicate this specifically and mechanistically, not as vague reassurance.
- ●Weight loss target: A sustained reduction of 7–10% of total body weight resolves steatosis and can reverse early fibrosis. For Paul at approximately 95–100 kg, this means 7–10 kg.
- ●Diet: The Mediterranean diet (high in olive oil, oily fish, legumes, vegetables, and whole grains; low in refined carbohydrates, processed foods, and saturated fat) is the most evidence-based dietary pattern for reducing hepatic fat, with benefits independent of weight loss alone.
- ●Physical activity: Both aerobic exercise and resistance training reduce hepatic fat content independently of body weight. Aim for at least 150 minutes of moderate-intensity exercise per week.
- ●Alcohol: Advise Paul to remain within the NHS limit of 14 units per week, spread across several days with alcohol-free days included. Reducing intake further during the recovery period will accelerate improvement — the liver cannot efficiently metabolise stored fat while simultaneously processing alcohol.
- ●Structured support: Lifestyle advice alone has limited long-term efficacy. Refer to an NHS Tier 2 weight management programme (or local equivalent) — particularly important given Paul's obesogenic occupational environment.
Referral Criteria
- ●Refer to hepatology if: FIB-4 is indeterminate (1.30–2.67) for ELF testing or FibroScan; or FIB-4 is high (>2.67) for formal assessment and biopsy consideration.
- ●Refer for sleep clinic assessment if the Epworth Sleepiness Scale score or clinical picture suggests significant OSA.
- ●Refer to NHS Tier 2 or Tier 3 weight management based on BMI and comorbidity profile — Paul meets criteria for Tier 2 referral.
- ●Urgent or 2WW referral is not indicated in this presentation: there are no features of decompensated liver disease or hepatocellular carcinoma risk requiring expedited secondary care assessment.
Safety Netting and Follow-up
- ●Arrange review in 3–4 months to reassess LFTs, weight, HbA1c, fasting lipids, and blood pressure — providing a clear, structured endpoint for the lifestyle intervention.
- ●Advise Paul to return sooner if he develops: new jaundice, dark urine, pale stools, abdominal swelling, easy bruising, or new right upper quadrant pain — these would prompt urgent reassessment for decompensated liver disease.
- ●Establish a pattern of annual FIB-4 recalculation if the initial result is low-risk, to detect disease progression over time.
- ●Safety-netting should be specific and named, not generic — a concrete list of return symptoms is more actionable than an instruction to "come back if worried."
Common Candidate Mistakes in This Case
- ●Failing to quantify alcohol in units: Accepting "a few beers at weekends" without calculating a weekly unit total is insufficient to differentiate MASLD from ALD with confidence.
- ●Reassuring from the scan alone: The ultrasound confirms steatosis but gives no information about fibrosis. Offering reassurance without performing FIB-4 risk stratification misses the core NICE-recommended step.
- ●Missing the cardiovascular workup: Focusing exclusively on the liver and omitting HbA1c, fasting lipids, and QRISK3 is a common and significant gap — the cardiovascular risk profile here is as clinically important as the hepatic finding.
- ●Withholding statins due to the liver result: A mildly raised ALT in MASLD is not a contraindication to statins. Deferring cardiovascular risk management on this basis is both incorrect and potentially harmful.
- ●Vague lifestyle advice: "Eat better and exercise more" without specifying the 7–10% weight loss target, the Mediterranean diet framework, or a referral to structured support is clinically insufficient.
- ●Ignoring OSA: An obese, fatigued male with heavy snoring and MASLD should prompt active screening for obstructive sleep apnoea — a modifiable driver of disease progression that candidates routinely overlook.
Patient Communication — What Works in This Case
- ●Paul's fear is not of MASLD — it is of cirrhosis and dying like his father. Until that fear is directly addressed and explicitly dismantled, clinical information will not land. The diagnostic explanation must come first: this is not the same disease his father had; the causes are different, the prognosis is different, and the trajectory can be reversed.
- ●The concept of reversibility is the most powerful communication tool in this case. Frame it mechanistically: with sustained weight loss, the liver actively breaks down and clears the stored fat — the process is not permanent, and the liver has not been permanently scarred at this stage.
- ●Paul responds well to agency and data: the FIB-4 calculation functions as a test that can objectively quantify his current risk level, meeting his stated expectation for evidence-based information rather than vague reassurance.
- ●Avoid the word "disease" where possible when first framing the diagnosis — "fat in the liver" is more accessible and less frightening. Introduce the formal terminology once the patient is in a receptive state.
