Patient Script
For the friend playing the patient role
Character Overview: You are Hilary Costello, 64, who works Monday, Wednesday and Friday at a dry cleaner's, serving on the counter and working the pressing machines. You live with your husband Dermot, 68, retired with bad knees. Your daughter Sorcha works full time and you collect her children, Fintan, 7, and Maeve, 5, from school every Tuesday and Thursday. You are in the village amateur dramatic society, rehearse on Wednesday evenings, and have a big speaking part in about three months. You are warm, practical and a bit stubborn, you hate fuss and do not think of yourself as a patient. Your calcium has been checked every year for two years and nobody has told you to do anything. Your friend Rosalind, 66, also in the society, had an operation on her neck for the same thing eighteen months ago, and you have thought about it ever since your latest bloods. You sound cheerful and chatty, but become defensive if you feel pushed towards an operation.
Opening Sentence: "Hello doctor, thanks for ringing. It's about my calcium. It's been a bit high for a couple of years and they check it every year. My friend Rosalind had an operation on her neck for the same thing and I'd really rather not have one. Do I actually need it?"
History if Asked (Data Gathering Phase)
- ●When it was found and what she was told: "Two years ago, at my blood pressure check. They said my calcium was a bit high, probably from one of the little glands in my neck, and we'd keep an eye on it. They've checked it every year since. Nobody has said I had to do anything and I've never seen a specialist."
- ●How she is in herself (general question): "I feel fine, really. I just get on with things."
- ●Thirst, passing urine and drinking (only if asked): "Now you mention it, I am thirsty a lot. I take a big bottle to work and keep a glass of water by the bed. About a year. I pass water more than I used to, every couple of hours in the day and about three times a night, a little worse than six months ago. No burning and no blood, just a lot of it. I put it down to getting older and six or seven cups of tea, and two and a half litres of water."
- ●Bowels (if asked): "A bit sluggish, but I've always been like that and I have prunes. No tummy pain."
- ●Tiredness, aches, memory and mood (if asked): "I'm tired by the afternoon, but I'm 64 and on my feet. Aches in my hips and lower back, nothing awful, I put it down to lifting laundry bags. I'm losing words a bit and learning my lines more slowly, which I thought was age. My mood's a bit flat some days."
- ●Weight, appetite, sweats (if asked): "My weight's the same. I eat well. No night sweats."
- ●Kidney problems (if asked about stones, loin pain, blood in the urine or infections): "No, never. I can't remember the last time I had an infection. I've never had a scan of my kidneys."
- ●What has been done so far (if asked): "The nurse sent me for a bone scan about six weeks ago. She said my bones were a bit thinner than they'd like. Other than that just the blood tests."
Ideas, Concerns, Expectations
Gating note: Hilary raises none of these herself. Each comes out only when the doctor asks what she thinks is going on, what worries her, or what she was hoping for.
- ●Ideas: A number on a blood test that is a little bit up, not something making her ill. Operations are for people who are properly poorly. "I'm not poorly, am I? It's just a number."
- ●Concerns: The operation itself. She fears for her voice, because Rosalind was croaky for a month and missed the show, and she has a big part coming up. Sorcha depends on her on Tuesdays and Thursdays and Dermot cannot lift the children. She dislikes the idea of a general anaesthetic and a neck scar. If the doctor explores further or mentions her bones, a quieter worry comes out: her mother broke her hip at 82 and was never the same. "Is that where this is going?"
- ●Expectations: To be told she can leave it alone, or that there is a tablet instead.
If Asked: Medical History and Medications
Gating note: Hilary answers each of these plainly when asked.
- ●Other problems and tablets: "Just my blood pressure, about five years. Amlodipine, one a day, never changed. No water tablets. No lithium."
- ●Supplements: "Vitamin D, a thousand units a day, the chemist suggested it a couple of years ago. No calcium tablets, no antacids, no herbal things."
- ●Diet and dairy: "Milky tea, a yoghurt most days, cheese on toast now and again. I've never cut dairy out."
- ●Family history: "Nobody with kidney stones, high calcium or glands. My mum broke her hip at 82."
- ●Bones and fractures (if asked): "I've never broken anything as an adult. No back pain more than a twinge, I haven't got shorter, I'm steady on my feet and haven't fallen."
- ●Periods, steroids, smoking, alcohol: "Periods stopped at 52, never took HRT. Never had steroids. Never smoked. A small glass of wine two or three nights a week."
- ●What Rosalind had (if asked): "She had it done eighteen months ago. Overnight in hospital, her fingers tingled that first night so they gave her calcium tablets, and her voice was croaky for about a month. Now she says she feels ten years younger and wishes she'd done it sooner."
Social History and Lifestyle Impact
Gating note: Hilary mentions these naturally when talking about her worries.
- ●Work and home: On her feet most of the day, lifting heavy bags of laundry. Owns her house. Dermot is supportive but cannot lift. Sorcha lives ten minutes away.
- ●Lifestyle impact: "I'm shattered by the afternoon and I plan where the toilets are when I'm out. Dermot says I'm always banging about at night. I thought that was how it is at 64."
- ●Hobbies: Rehearsals on Wednesday evenings. She walks to the bus and does the garden.
If Asked: Associated Symptoms
Gating note: Hilary answers symptom questions in one short sentence.
- ●Vomiting, nausea or poor appetite, confusion or drowsiness, palpitations or chest pain, headaches or vision change, weight loss or night sweats, a recent fall: "No."
- ●A lump in her neck: "I haven't noticed anything, and I wouldn't know what I was feeling for."
- ●New medicines: "No, nothing's changed."
Responses to Management (The Negotiation Phase)
- ●If the doctor says she meets the criteria to see a surgeon, or recommends referral:
- ●Reaction: Alarmed at first. "Oh. So I do need the operation?" If told that seeing the specialist is a conversation and the decision stays with her: "Right, a chat I can do. How long would I be waiting? What would they actually do?" Asked what she would prefer: "I'd rather not, I'll be honest. But I'm not daft. If you think I should be seen, I'll go and listen." If the doctor links thirst, frequent urine or tiredness to the calcium: "Really? I thought that was my age. Would it get better if it was sorted?"
- ●If the doctor suggests monitoring only, or asks what happens if she leaves it:
- ●Reaction: If monitoring only, pleased, without having been asked about thirst or urine: "Oh, that's a relief. I'll just crack on then." She does not mention her symptoms unless asked. If asked what happens if she leaves it: "Would it do any harm?" She is more receptive to an honest answer than a vague one. Asked how often she would need checking: "And what would make you say I had to have it done after all?"
- ●If the doctor explains what the operation involves or discusses her voice:
- ●Reaction: Practical questions: "How long would I be in? When would I be back at work? Could I do the school run?" On her voice, if honest and balanced: "One in a hundred. That's not nothing for someone in my position, but it's better than I thought. I'll tell them about the show." If told there is no risk: "But Rosalind's went for a month. Are you sure?" If the doctor offers to tell the specialist about the show: "Yes, please. That would be a weight off my mind."
- ●If the doctor asks about her bones or the scan:
- ●Reaction: "Is that the same as brittle bones? Am I going to end up like Mum?" Calmer if told what the scan means, that her risk can be worked out and what will be done about it.
- ●If the doctor sets out options, mentions tablets or suggests tests:
- ●Reaction: "Isn't there a tablet I could take instead?" Told tablets are for people who cannot have the operation: "So I wouldn't get them yet?" She accepts it with a clear reason. Told of a kidney scan or blood tests: "Where would I go? Do I need to do anything beforehand?" A hormone specialist rather than a surgeon: "Would they operate?" Content once told they assess her first. If asked to feel her neck or check anything herself, she declines politely.
- ●If the doctor gives advice on food, drink or supplements, or safety netting:
- ●Reaction: "Should I stop my vitamin D? Should I stop milk and cheese? Should I be drinking more or less?" Told "come back if it gets worse": "Worse how? What would mean I should ring someone, and what would mean an ambulance?"

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Hilary, 64, has had a raised calcium and PTH for two years, monitored in the practice and never referred. She opens by asking whether she needs an operation, hoping to hear she can leave it or take a tablet.
- ●The skill is to find the symptoms she has put down to age (thirst, frequent urine by day and night), recognise that they change the answer, and recommend specialist referral without presenting surgery as compulsory.
- ●Model plan: explain the diagnosis; recommend referral to a parathyroid surgeon or endocrinologist per the local pathway; explain the options and keep the decision hers; arrange kidney ultrasound and a fracture risk assessment; give fluid and diet advice; agree monitoring, triggers to revisit surgery and safety netting.
Primary Hyperparathyroidism: What It Is and How It Is Found
- ●One or more parathyroid glands make too much parathyroid hormone (PTH), raising the calcium. A single overactive gland (adenoma, not cancer) causes about 85 in 100 cases.
- ●NICE CKS (hypercalcaemia, June 2026) defines hypercalcaemia as an adjusted calcium of 2.6 mmol/L or more on two occasions. With a raised PTH, primary hyperparathyroidism is the likeliest cause. NICE NG132 advises measuring PTH when calcium is raised twice, and looking for other causes including malignancy if PTH is low. PTH should not routinely be repeated in primary care.
- ●Secondary care adds vitamin D, urine calcium (to exclude familial hypocalciuric hypercalcaemia), eGFR, DXA and a renal tract ultrasound.
- ●Hilary fits: adjusted calcium 2.68, 2.70 and 2.72, PTH 8.4 (reference 1.6 to 6.9), normal vitamin D, stable eGFR and normal HbA1c.
Symptoms That Are Easy to Miss
- ●NG132 names thirst, frequent or excessive urination and constipation as the symptoms of hypercalcaemia. Tiredness, aches, low mood, mild confusion and slower thinking are non specific and matter less for the decision.
- ●People are often labelled asymptomatic when it is found. Symptoms creep up and are put down to age or tea, so ask directly at each review.
- ●Hilary has had thirst and passing urine by day and night for about a year. Diabetes is excluded (HbA1c 37, clear dipstick), she takes no diuretic and her amlodipine is unchanged. The symptoms began as the calcium crept up, so they count.
Who Should Be Referred
- ●NG132 advises referral to a surgeon with parathyroid expertise for people with symptoms of hypercalcaemia (thirst, frequent urination, constipation), end organ disease (renal stones, fragility fractures or osteoporosis) or an adjusted calcium of 2.85 mmol/L or more. It also advises considering referral when none is present, and CKS advises endocrinology referral for mildly raised calcium with a raised PTH. Either route is acceptable according to the local pathway.
- ●Hilary's calcium of 2.72 is below 2.85 and her lowest T score of minus 2.0 is osteopenia (osteoporosis is minus 2.5 or less). She has no stones or fractures. But she has symptoms, so she meets the criteria, and referral would also be supported without them.
- ●Referral is not consent to an operation. It gives her the information to decide, and her earlier choice to monitor was made before the symptoms developed.
Surgery: Benefits and Risks
- ●Surgery is the only cure. It relieves thirst, frequent urine and constipation and can prevent later stones and fractures. About one third of people who start with no indication for surgery go on to develop stones or fractures.
- ●It is done under general anaesthetic. For a single adenoma on imaging, NICE advises offering a choice of focused parathyroidectomy (shorter, smaller scar, less temporary low calcium, slightly higher chance of recurrence, about 5%) or four gland exploration. Most people go home the next day, return to office work in two to three weeks and heavier work in about four.
- ●Calcium stays high after surgery in 3 to 5 in 100. Permanent injury to one recurrent laryngeal nerve, giving a hoarse weak voice, occurs in about 1 in 100. A bruised nerve usually recovers over days to months. Injury to the external branch of the superior laryngeal nerve makes projecting the voice harder, so people who depend on their voice should tell the surgeon.
- ●Calcium can fall after surgery, causing tingling in the lips, fingers or toes. It is almost always temporary. Permanent low PTH is rare.
Non Surgical Options
- ●Cinacalcet is considered when surgery has failed, is unsuitable or is declined and the adjusted calcium is 2.85 or more with symptoms, or 3.0 or more with or without symptoms. It sits within specialist management. At 2.72 it is not supported for Hilary.
- ●NG132 advises considering a bisphosphonate to reduce fracture risk in primary hyperparathyroidism, not to treat the calcium. NG259 (July 2026) advises considering pharmacological treatment for a woman after the menopause with a T score of minus 1.5 or lower and primary hyperparathyroidism not treated with surgery, and seeking specialist advice. Hilary's spine T score of minus 2.0 and untreated gland make bisphosphonate a legitimate shared decision. Alendronic acid is 70 mg once weekly, with calcium disturbance corrected first and avoided if creatinine clearance is under 35 mL/minute. Starting it in the practice after discussion, or leaving it to the specialist, are both acceptable.
Kidney, Bone and Monitoring
- ●Kidney: yearly eGFR or creatinine, and a renal tract ultrasound at diagnosis and if a stone is suspected. Hilary's eGFR has drifted from 76 to 71 but is above 60, and no imaging has ever been done.
- ●Bone: DXA of lumbar spine, distal radius and hip (her scan did not include the radius). Repeat every 2 to 3 years while monitoring, and not routinely within 2 years of the last. An X ray or vertebral fracture assessment is appropriate with back pain or height loss.
- ●Fracture risk: hyperparathyroidism raises fracture risk. NG259 advises FRAX or QFracture for people aged 40 to 90. A first degree relative's hip fracture is an extra risk factor, with more weight if under 80 (her mother was 82). Cardiovascular risk should also be reviewed.
- ●Monitoring: yearly calcium and eGFR or creatinine. Refer again for worsening symptoms, adjusted calcium of 2.85 or more, eGFR below 60, a stone, osteoporosis on DXA or a fragility fracture. Monitoring does not replace specialist assessment. It is used while waiting, or if she decides against surgery after an informed discussion, and can be revisited at any time.
Advice and Safety Netting
- ●Advise adequate fluids, a usual and not excessive dietary calcium, and avoiding thiazide diuretics, calcium containing antacids, excess vitamin A or D and NSAIDs. Vitamin D should be replete (hers is 71 on 1000 units daily) with any change made by the specialist. Do not make dietary changes just to lower calcium.
- ●Emergency: an adjusted calcium above 3.5 or severe symptoms needs hospital admission. In practice, repeated vomiting, marked drowsiness, confusion or dehydration need 999 or same day emergency assessment.
- ●Severe loin pain, blood in the urine, loin pain with fever or a suspected broken bone after a minor fall need same day assessment. New back pain or worsening thirst and frequency need a prompt GP appointment.
- ●Avoid "come back if it gets worse". Tie each symptom to a disposition.
Sharing the Decision
- ●Answer her question directly, show that her thirst and night time urination change the answer, and make clear that a specialist appointment is a conversation. If she still declines after an honest discussion, document the informed decision, agree monitoring and leave the door open.
- ●Her worries are her voice, childcare on two days and her mother's hip fracture. Answer each with accurate figures and a clear next step, and tell the surgeon about her voice use.
Common Mistakes in This Station
- ●Calling the calcium mildly raised and leaving it, without asking about symptoms or offering referral.
- ●Treating osteopenia as an indication for surgery, or as nothing to worry about.
- ●Missing thirst and night time urination, or putting them down to age or tea.
- ●Offering cinacalcet or a bisphosphonate to lower the calcium at 2.72.
- ●Telling her to cut out dairy, restrict fluids or take calcium supplements.
- ●No kidney ultrasound and no fracture risk assessment.
- ●Promising there is no risk to her voice, or not suggesting she tells the surgeon.
- ●Presenting surgery as compulsory.
- ●Vague safety netting with no disposition for each symptom.
