Patient Script
For the friend playing the patient role
Character Overview: You are Brenda, a 78-year-old widow. You are fiercely proud of your independence and very active in your local community—you attend a bridge club on Wednesday mornings, church on Sundays, and regularly take the bus to the local garden centre. However, over the last few weeks, your heart failure has flared up. You are breathless walking up the stairs in your house and have to sleep propped up on three pillows. You know exactly why this is happening: you have stopped taking your "water pill" (Furosemide). When you take it, you experience a sudden, uncontrollable urge to urinate that lasts for hours. Three weeks ago, you couldn't get to the toilet in time at the garden centre and wet yourself. You were mortified and had to get a taxi home soaked. You have decided that you would rather be breathless than ever suffer that humiliation again. You will not volunteer that you are skipping your medication or mention the incontinence incident unless the doctor specifically asks how you are getting on with your pills, asks about side effects, or creates a highly non-judgmental, safe space on the telephone call.
ICE — Ideas, Concerns, Expectations (Do not volunteer any of this unprompted. These responses surface only if the candidate directly explores your perspective.)
- ●
Ideas: You are fairly sure the breathing and swelling are your heart playing up again — you've been through this before and recognise the pattern. You suspect it's because you stopped the water pill, but you feel you had no choice.
- ●
Concerns: Your biggest fear is losing your independence and your dignity. You are terrified of being housebound — unable to go to bridge club or church — or of having another public incontinence episode. You are also privately worried that your heart is getting worse and that one day the breathlessness won't settle down. But the humiliation of wetting yourself in public weighs more heavily on you right now than the medical risk.
- ●
Expectations: You want the doctor to actually listen and understand why you stopped the tablet, not just lecture you. Ideally, you'd like a solution that lets you manage the breathing without being chained to the bathroom all morning. You'd accept a compromise — a different way of taking the medication, or some practical help with the continence problem — as long as it lets you keep going to your clubs.
Consultation Flow & Responses:
- ●The Opening
- ●If the doctor asks an open question: "Good morning, Doctor. I've booked this telephone call because my breathing is getting terrible again. I can barely make it to the kitchen without having to sit down, and my shoes won't fit because my feet are so swollen."
- ●Data Gathering (The Layers)
- ●Layer 1: Heart Failure Symptoms (Verbal Fluid Assessment):
- ●"I'm puffing and panting just walking around the house. I even feel breathless talking to you on the phone right now."
- ●"I have to sleep on three pillows now, otherwise I wake up gasping for air." (Orthopnoea).
- ●"My slippers are leaving deep grooves in my skin because the swelling is so bad."
- ●"No chest pain, no fainting. Just the breathing."
- ●Layer 2: The Medication Trap (Checking Compliance):
- ●If the doctor just asks "Are you taking your tablets?": "I take the blood pressure ones and the heart ones every single day without fail." (Deliberately omitting the Furosemide).
- ●If the doctor specifically asks about the Furosemide / "water pill": "Well... I take that one when I can. But mostly, no. I haven't taken it in about three weeks."
- ●Layer 3: The Hidden Barrier (The Incontinence):
- ●If the doctor asks WHY she stopped taking it: You sound tearful and embarrassed over the phone. "Doctor, those water pills are a curse. Within 30 minutes of taking one, I have to run to the toilet, and I mean run. Three weeks ago at the garden centre... I didn't make it. I wet myself in public. I had to get a taxi home soaked. I can't live like that."
- ●Layer 4: ICE & Quality of Life (The Trade-off):
- ●If the doctor tells you that you HAVE to take it or your heart will fail:
- ●Reaction (The Reveal): Defiant. "Then my heart will just have to fail! I am 78 years old. My bridge club and my church are my only reasons to get out of the house. If I take that pill in the morning, I am trapped in my bathroom until 2 PM. I'd rather be out of breath sitting in church than locked in my house smelling of urine."
If Asked — Medical History and Medications (Respond only if the candidate asks directly about these items.)
- ●
Bisoprolol (5mg): "That's one of the heart tablets, isn't it? I take that every morning with my breakfast. I've been on it for years now — no problems with it at all. I don't feel dizzy or anything like that."
- ●
Ramipril (2.5mg): "Yes, that's my blood pressure one. I take it every day. I don't think it causes me any trouble — no cough or anything."
- ●
Dapagliflozin (10mg): "The newer one they added last year? Yes, I take that. The doctor at the hospital said it was good for my heart. It does make me pass a bit more water, but nothing like the Furosemide — it's gentle, I can manage it."
- ●
Osteoarthritis: "My knees have been stiff for years, but I manage. I take paracetamol if they're bad. It doesn't really bother me much at the moment — the breathing is the main thing."
- ●
Heart failure review (6 months ago): "I saw the nurse about six months ago and she said everything was ticking along nicely. My blood tests were fine. That was before all this started — I was managing much better then because I was still taking the water pill."
Social History and Lifestyle Impact (This content can be volunteered naturally in conversation, woven into responses about how the condition is affecting daily life.)
- ●
Daily life context: Brenda lives alone in a small terraced house since her husband Arthur passed away four years ago. She has one daughter, Karen, who lives about an hour away and visits every other weekend. She is fiercely independent — she does her own shopping, cooking, and housework. Her week revolves around bridge club on Wednesdays, church on Sundays, and trips to the garden centre.
- ●
Lifestyle impact of the condition: "I haven't been to the garden centre since the... incident. I missed bridge club last Wednesday because I couldn't face getting the bus feeling this breathless — I was worried I'd have to get off halfway. I even had to sit in the porch at church last Sunday because I couldn't walk to my usual pew at the front. My daughter keeps saying I should move in with her, but I won't. This is my home. I just need to be able to breathe well enough to get on with things."
If Asked — Associated Symptoms (Respond only if the candidate asks directly about these symptoms.)
- ●
If asked about waking up suddenly at night gasping for breath (PND): "Now you mention it, yes — a couple of times in the last week I've woken up in the middle of the night fighting for air. I had to sit bolt upright and it took a good ten minutes to settle. It was quite frightening."
- ●
If asked about weight gain: "I haven't weighed myself, but my clothes feel tighter around my middle and my rings are digging in. I'd say I've probably put on a few pounds just from the swelling."
- ●
If asked about cough: "I do get a bit of a dry cough at night when I'm lying down, but nothing during the day and I'm not bringing anything up."
- ●
If asked about palpitations or irregular heartbeat: "No, nothing like that. My heart doesn't race or skip — it's just the breathing."
- ●
If asked about reduced urine output (when not taking Furosemide): "Actually, now you say it, I have noticed I'm not going to the toilet as much as I used to. Maybe three or four times a day? But the swelling in my legs is much worse, so I suppose the water is going there instead."
- ●
If asked about fever or signs of infection: "No, I don't feel unwell in that way — no temperature, no shivering. I just can't catch my breath."
- ●
If asked about blood in sputum (haemoptysis): "No, nothing like that. I haven't coughed up any blood."
- ●
If asked about leg pain, redness, or warmth in one leg (DVT screen): "No, both legs are equally puffy. Neither one is red or hot or painful — just swollen."
- ●
If asked about diet or fluid intake: "I eat sensibly — I cook for myself most days. I probably have about four or five cups of tea a day and a glass of water. I don't add salt to things."
- ●
If asked about alcohol: "The occasional sherry at church. Nothing more than that."
- ●
If asked about smoking: "Never smoked in my life, Doctor."
Negotiation & Collaborative Management Plan
- ●If the Doctor scolds you for stopping the medication:
- ●Reaction: "It's easy for you to just say 'take the pill'. You don't understand what it's like to lose your dignity."
- ●If the Doctor suggests taking the Furosemide at a different time of day (Flexible Dosing):
- ●Reaction: Surprised. "You mean I don't have to take it in the morning? If I go to bridge club at 10 AM, I could just take the pill when I get home at 3 PM?"
- ●If the Doctor suggests halving the dose but taking it twice a day to reduce the sudden 'rush':
- ●Reaction: "So it would be a steady trickle rather than a flood all at once? That sounds much more manageable."
- ●If the Doctor mentions a referral to the continence service / getting discrete pads:
- ●Reaction: "I've been too embarrassed to buy those adult pull-ups at the pharmacy. If a nurse could give me some advice on proper pads for when I go out, that would make me feel much safer."
- ●Safety Netting / Follow-up
- ●If the Doctor sets a plan to check her kidneys (blood test) and review the flexible dosing in a week:
- ●Reaction: "Alright. I'll take it this afternoon when I know I'm staying in, and I will come down to the surgery for the blood test tomorrow. Thank you for listening to me."
Additional Scripted Responses (Data Gathering):
- ●If asked whether she weighs herself regularly: "I haven't got scales. The nurse mentioned it once but I forgot about it. Should I have been doing that?"

Domain 2: Clinical Management and Medical Complexity
Domain 3: Relating to Others
Clinical Learning Points
Recognising Decompensated HFrEF — The Clinical Picture
- ●Acute decompensation of Heart Failure with Reduced Ejection Fraction (HFrEF) typically presents with worsening dyspnoea, orthopnoea, paroxysmal nocturnal dyspnoea (PND), and increasing peripheral oedema — the same triad Brenda demonstrates here.
- ●Orthopnoea (sleeping propped on multiple pillows) and PND (waking gasping for air) are cardinal markers of elevated left ventricular filling pressure and pulmonary venous congestion. Both must be specifically asked about — they will not always be volunteered.
- ●A rise from NYHA Class II (stable six months ago) to effectively Class III–IV (limited on minimal exertion, unable to walk across the kitchen) represents significant clinical deterioration and should prompt both an acute management plan and consideration of specialist review.
Remote Fluid Assessment — Telephone-Adapted History
- ●In a telephone consultation, physical examination is unavailable. The clinician must translate the standard clinical assessment into functional, verbal questions that proxy for what would normally be observed or measured.
- ●Useful prompts: "Can you still get your shoes on?" (peripheral oedema), "How many pillows are you sleeping on?" (orthopnoea), "Are you breathless talking to me right now?" (severe dyspnoea at rest), "Have your clothes or rings felt tighter?" (fluid retention).
- ●Establishing the ability to speak in full sentences is a rapid, reliable proxy for respiratory reserve on a phone call.
- ●NICE CKS Heart Failure recommends assessing functional capacity and fluid status at every review; these questions operationalise that assessment remotely.
Non-Adherence in Older Adults — The Rational Trade-off
- ●Non-adherence in older patients is almost never simple forgetfulness. It is overwhelmingly a rational, values-based decision in response to an adverse effect that threatens quality of life — and it should be approached as such.
- ●Accepting a blanket "I take all my tablets" at face value is a diagnostic failure in this case. Each medication — particularly the diuretic — must be asked about individually and specifically.
- ●When non-adherence is identified, the clinical priority is to explore why with curiosity and without reproach. The reason will determine the solution.
- ●For an older patient whose social participation is the cornerstone of their mental health and independence, the perceived cost of a medication (being housebound for hours) will routinely outweigh its abstract benefit (reducing the risk of hospitalisation). Acknowledging this trade-off explicitly is not colluding with poor adherence — it is the basis of patient-centred medicine.
Flexible Diuretic Dosing — Practical Strategies
- ●Furosemide (a loop diuretic) blocks the Na-K-2Cl symporter in the thick ascending limb of the loop of Henle, producing a rapid, high-volume diuresis typically peaking within 1–2 hours of ingestion and lasting 4–6 hours.
- ●There is no absolute physiological requirement for morning dosing. Empowering patients to time their diuretic around their social commitments (e.g. taking it on return home at 3 PM rather than 8 AM) dramatically improves real-world adherence without compromising daily fluid offloading.
- ●Dose splitting — for example, converting furosemide 40mg once daily to 20mg twice daily — flattens the peak diuretic effect, reducing urinary urgency while maintaining total daily diuresis. This is a well-recognised pragmatic strategy in clinical practice.
- ●Where a patient has a single, infrequent high-value social event (e.g. a wedding, a long journey), a planned single-dose omission — agreed in advance with the clinician — is preferable to the patient unilaterally stopping the medication altogether.
Urge Incontinence as a Diuretic Side Effect — Diagnosis and Management
- ●Furosemide-induced urge incontinence is common and under-recognised. The rapid, high-volume diuresis overwhelms bladder capacity and urgency sensation, particularly in older women with pre-existing detrusor overactivity or reduced mobility.
- ●First-line management per NICE CKS Urinary Incontinence in Women (and CKS Urinary Incontinence in Men for completeness): supervised pelvic floor muscle training, bladder training (progressively extending voiding intervals), and lifestyle advice (fluid timing, caffeine reduction).
- ●Continence service referral: community continence nurses can provide structured bladder training programmes, high-quality continence products for use during social activities, and specialist assessment. This referral is appropriate here — do not limit the response to pad provision alone.
- ●Practical interim measures — including continence pads for social outings and planned toilet stops before leaving home — should be offered immediately, alongside the longer-term referral, to restore the patient's confidence.
Renal Monitoring Before Restarting Diuretics
- ●Three weeks of Furosemide non-adherence in a patient also taking ramipril (an ACE inhibitor) and dapagliflozin (an SGLT2 inhibitor) creates a clinically significant risk of undetected renal impairment or hyperkalaemia.
- ●U&Es (including creatinine, eGFR, sodium, and potassium) must be checked within 1–2 days before or on restarting diuretic therapy — not at the routine one-week review.
- ●NICE CKS Heart Failure explicitly recommends monitoring renal function and electrolytes after any change in diuretic dose or following a period of non-adherence.
- ●Hypokalaemia (from loop diuretic effect) and hyperkalaemia (from ACE inhibitor and SGLT2i in the context of relative dehydration or renal impairment) are both plausible in this patient — the U&E result will determine safe next steps.
Polypharmacy Context — Dapagliflozin in HFrEF
- ●Dapagliflozin (an SGLT2 inhibitor) is now a standard component of disease-modifying therapy in HFrEF, alongside ACE inhibitors/ARBs, beta-blockers, and loop diuretics — reflecting the four-pillar model of HFrEF pharmacotherapy.
- ●SGLT2 inhibitors exert a mild osmotic diuretic effect, which is distinct from — and additive to — loop diuretic action. Brenda tolerates dapagliflozin without urgency symptoms, which confirms that the urge incontinence is specifically driven by furosemide's peak diuretic effect rather than her total diuretic burden.
- ●This distinction matters clinically: it justifies targeting furosemide timing and dose rather than reducing or stopping dapagliflozin, which carries clear mortality benefit in HFrEF.
When to Consider Specialist Review
- ●An acute decompensation episode in a patient with known HFrEF — particularly one associated with a documented change in NYHA class — should prompt consideration of heart failure specialist nurse (HFSN) review or cardiology outpatient referral.
- ●NICE NG106 (Chronic Heart Failure in Adults) recommends that patients with worsening symptoms despite optimal pharmacotherapy are reviewed by a specialist heart failure team.
- ●Community HFSNs can offer home visits, structured self-monitoring (daily weight, symptom diary), supported diuretic self-titration, and education — all of which are directly relevant to Brenda's case and would reduce her risk of future decompensation.
- ●Indications for same-day emergency referral include: breathlessness at rest with inability to complete sentences, acute haemodynamic compromise, new chest pain, or acute confusion — none of which are present here, but all of which must be actively screened for on the telephone.
Safety-Netting — Specific to This Case
- ●Safety-netting on a telephone call for decompensated heart failure must be explicit and specific — not a generic "call if you feel worse."
- ●Brenda should be told to call 999 or attend A&E immediately if: she becomes breathless at rest and cannot complete a sentence, she develops chest pain, she experiences acute confusion, or she wakes gasping and cannot settle within a few minutes.
- ●She should be advised to call the surgery the same day if her swelling or breathlessness worsens significantly before her review, or if she develops any symptoms of dizziness, faintness, or palpitations after restarting furosemide.
- ●A structured follow-up — not open-ended — should be arranged: typically within one week to review symptoms, U&E results, and tolerance of the revised dosing schedule, with explicit criteria for escalation if symptoms have not improved.
