- Drug history: Ramipril 5mg once daily, Allopurinol 100mg once daily. No known drug allergies.
- Recent consultations/Results: Seen by HCA 3 days ago for a routine blood pressure check. BP was 145/90 mmHg. A random fingerprick blood glucose was done and was high at 15.2 mmol/L. A urine dipstick test showed Glucose +++ and Ketones +. He was advised to book an urgent appointment with the GP.
Patient’s Story (Role-Player Brief)
You are David Miller, a 52-year-old self-employed taxi driver. You’re here because the practice nurse told you to make an urgent appointment after a routine check showed high blood sugar. You’re not overly worried; you think it’s just “a touch of sugar.”
- Presenting Complaint: You’ve been feeling “a bit off” for the last 3 months. You’re more tired than usual, getting up twice a night to pass urine, and always feel thirsty. You’ve lost about 4 kg in weight, but you’ve put this down to the stress of working long hours. You feel the symptoms are a nuisance rather than a major problem.
- Key Information (Reveal only if asked directly):
- Your father was diagnosed with Type 2 diabetes in his 60s and managed it with tablets.
- You have no personal or family history of any autoimmune diseases (like thyroid problems, coeliac disease, etc.).
- You haven’t had any recent illnesses, stomach pain, or pancreatitis.
- ICE (Ideas, Concerns, Expectations):
- Ideas: “I think it’s just Type 2 diabetes, like my dad had. I’m a bit overweight and getting older, so it makes sense. I probably just need to cut down on sweets.”
- Concerns: “My biggest worry is my job. If I have to go on insulin or something, will I lose my taxi license? I’m the main earner and we can’t afford for me to be off the road.”
- Expectations: “I was hoping you could just give me a tablet to sort it out so I can get back to normal.”
- Psychosocial Context: You work long and often irregular hours as a taxi driver to support your family. Your diet is poor; you often grab takeaways or snacks on the go. You drink 1-2 pints of beer most evenings to unwind. You feel stressed about finances.
- Role-Play Instructions: Initially, be quite dismissive of your symptoms. Emphasise your job and driving license as your main priority. If the doctor mentions Type 1 diabetes or insulin, show anxiety and resistance. Express fear about “hypos” (hypoglycaemia) and how that would affect your ability to drive safely.
Data Gathering & Diagnosis
- Phase 1: Open the Consultation & Explore the Presenting Complaint
- Rationale: To build rapport and gain a patient-centered understanding of the symptoms and the reason for the consultation.
- Key Questions:
- “The nurse asked you to book in after some tests a few days ago. Tell me a bit more about that.”
- “I see you’ve been feeling tired, thirsty, and passing more urine. How long has this been going on for?”
- “You’ve also lost some weight. How much have you lost, and over what period?”
- “How have these symptoms been affecting your day-to-day life and your work?”
- Phase 2: Broaden the Differential & Screen for Red Flags
- Rationale: To actively differentiate between Type 1, Type 2, and other less common causes of hyperglycaemia, while urgently screening for the life-threatening complication of Diabetic Ketoacidosis (DKA).
- Key Questions (To differentiate T1 vs. T2 vs. Others):
- “How quickly did these symptoms come on? Was it over a few weeks or more gradually over several months?” (Rapid onset suggests T1.)
- “Was the weight loss something you were trying to do, or has it happened without any change to your diet or exercise?” (Unintentional, rapid weight loss is a key feature of T1.)
- “Do you or any close family members have any other medical conditions, particularly autoimmune ones like thyroid problems or coeliac disease?” (Autoimmune history increases suspicion of T1.)
- “Have you had any severe abdominal pain recently, or any history of pancreatitis?” (Rules out pancreatitis as a cause.)
- “Are you on any new medications, particularly steroids?” (Rules out drug-induced diabetes.)
- Key Questions (To screen for DKA Red Flags):
- “Are you feeling sick or have you actually been vomiting?”
- “Do you have any stomach pain?”
- “Have you been feeling drowsy, sleepy, or confused?”
- “Has your wife or anyone else mentioned a fruity or unusual smell on your breath, a bit like pear drops?”
- “How is your breathing? Does it feel deeper or faster than normal?”
- Phase 3: Build the Clinical Context
- Rationale: To place the symptoms in the context of the patient’s overall health and identify relevant risk factors or comorbidities.
- Key Questions:
- “You mentioned your father had diabetes. Can you tell me more about that? What age was he diagnosed and what treatment did he have?”
- “Can you confirm the medications you are currently taking?”
- “Have you noticed any changes in your vision, like blurring?”
- “Have you had any tingling or numbness in your feet?”
- Phase 4: Understand the Patient’s Perspective & Impact
- Rationale: To conduct a holistic consultation by exploring the patient’s beliefs, worries, and goals, which is essential for shared decision-making.
- Key Questions:
- “What are your own thoughts on what might be causing these symptoms?” (Ideas)
- “What is your single biggest worry or concern about all of this?” (Concerns)
- “What were you hoping we could do for you today?” (Expectations)
- “Tell me a bit about your diet and your typical working day.”
- “How much alcohol do you drink in a typical week?”
Working Diagnosis
- Likely Diagnosis: New-onset Type 1 Diabetes in an adult (given the presence of ketonuria, weight loss, and relatively short symptom duration, despite the atypical age and BMI).
- Important Differential: Type 2 Diabetes with ketosis.
Diagnosis & Explanation
“David, thank you for sharing all that with me. I know you were thinking this might be Type 2 diabetes like your father had, and given your age, that’s a very understandable thought. However, the information we have, particularly the fact that you’ve been losing weight and that ketones were found in your urine, points strongly towards a diagnosis of Type 1 diabetes. This is a condition where the body stops producing insulin, which is a hormone we need to control blood sugar. I know this is a lot to take in, but I want to reassure you that this is a manageable condition, and there’s a lot of support available to help you.”
Management
- Referral: Arrange immediate, same-day referral to a multidisciplinary diabetes specialist team for confirmation of diagnosis and to start treatment.
- Investigations: No further investigations are needed in primary care. Explain that the specialist team will likely arrange further tests (like C-peptide or autoantibodies) if they feel it’s necessary.
- Medication: Explain that treatment, which will almost certainly be insulin, will be initiated and managed by the hospital specialist team.
- Lifestyle & Self-Care Advice:
- Provide initial basic advice on healthy eating and drinking plenty of sugar-free fluids.
- Explain that he will be offered a structured education programme (like DAFNE) by the specialist team to learn how to manage his condition, count carbohydrates, and adjust insulin.
- Driving Advice:
- Clearly and unequivocally advise him that he must stop driving immediately and must inform the DVLA about his diagnosis.
- Reassure him this is not necessarily permanent. Explain that he can reapply for his license once his blood glucose is stable and he meets the DVLA’s medical standards for insulin-treated diabetes, which the specialist team will help him achieve.
- Safety Netting:
- Provide explicit verbal and written safety netting for Diabetic Ketoacidosis (DKA). “It is very important that if you start vomiting, develop severe abdominal pain, become drowsy or confused, or if your breathing becomes deep and rapid, you or your wife must call 999 or go to A&E immediately.”
- Follow-up:
- Confirm the referral has been made and accepted today.
- Arrange a follow-up call in 2-3 days to check that he has been contacted by the specialist team and to offer further support.

GP: Hi David, I’m Dr. Smith. Thanks for coming in. I understand the practice nurse asked you to book an urgent appointment after your check-up a few days ago. To start, could you tell me a bit more about that from your side? (Skill: Open question, starting with the patient’s narrative as per Phase 1.)
Patient: Yeah, she did. To be honest, I think it’s all a bit of a fuss. She said my sugar was high. I feel a bit off, but I’ve just been stressed with work.
GP: I see. It can be a lot to take in when a test result is unexpected. You mention feeling “a bit off.” Can you tell me more about that? (Skill: Acknowledging the patient’s perspective before exploring symptoms.)
Patient: Well, for the last three months or so, I’ve just been knackered all the time. I’m having to get up a couple of times a night to go for a wee, which is annoying, and I’m thirsty all the time. I just can’t seem to drink enough.
GP: That sounds really draining. Feeling tired and thirsty like that must be difficult, especially with your job. The nurse also noted you’d lost a bit of weight. (Rationale: Directly exploring the key symptoms from the patient’s story as per Phase 1.)
Patient: That’s right, about 4 kilos. But I’ve been working long hours, grabbing food on the go… I just put it all down to stress. It’s a nuisance more than anything.
GP: Thank you for clarifying that. It’s really helpful to get the full picture. To figure out what’s happening and make sure we’re being safe, I need to ask some more specific health questions now. Would that be okay? (Skill: Signposting the shift from open to closed questions and framing it around safety.)
Patient: Sure, go ahead.
GP: Great. Firstly, have you had any tummy pain, felt sick, or actually been vomiting at all? (Rationale: Screening for key DKA red flags as per Phase 2. Starting with the most urgent questions.)
Patient: No, nothing like that.
GP: And have you been feeling more sleepy or drowsy than usual? Or has anyone noticed any change in your breathing? (Rationale: Continuing the DKA red flag screen.)
Patient: No, I’m just tired from the long shifts. Breathing is fine.
GP: Okay, that’s good to hear. Now, thinking about the symptoms you mentioned—the thirst and tiredness—did they come on quite suddenly over a few weeks, or was it more of a gradual thing over many months? (Rationale: Differentiating T1 vs T2 diabetes as per Phase 2. A rapid onset suggests Type 1.)
Patient: I’d say it’s been more over the last couple of months, really. It wasn’t a slow build-up over years or anything.
GP: And the 4kg of weight loss—that happened without you trying to lose it? (Rationale: Unintentional weight loss is a catabolic symptom, pointing towards insulin deficiency and Type 1 diabetes, as per Phase 2.)
Patient: Yeah, completely. I wish it was that easy when I wanted to lose weight!
GP: I understand. Just a couple more background questions. Do you or does anyone in your family have any conditions where the immune system is involved, like thyroid problems or coeliac disease? (Rationale: Screening for an autoimmune history, which increases the likelihood of Type 1 diabetes.)
Patient: Not that I know of. My dad had diabetes, though.
GP: Ah, okay. Can you tell me about your dad’s diabetes? (Rationale: Exploring relevant family history as per Phase 3.)
Patient: He got it in his 60s. Type 2, he called it. He just took some tablets for it.
GP: Thanks, David. That’s very helpful. Before we try and make sense of this, it’s really important I understand what’s on your mind. What were your own thoughts about what might be causing all this? (Skill: Explicitly moving to explore the patient’s Ideas, Concerns, and Expectations as per Phase 4.)
Patient: Well, with my dad having it, I just figured it’s my turn. You know, a touch of sugar. Type 2 diabetes. I’m getting older, a bit overweight… it just makes sense.
GP: That’s a very logical conclusion to come to. And what’s your biggest worry about it all? (Skill: Directly asking about Concerns.)
Patient: My job. One hundred percent. I’m a taxi driver. If I have to start taking insulin or something, will I lose my license? I’m the main breadwinner. We can’t afford for me to stop working. (Skill: The GP has now uncovered the patient’s core concern which must be addressed in the management plan.)
GP: Thank you for being so open about that, David. I can hear how much of a worry that is, and we will definitely talk about the driving. And in terms of today, what were you hoping I could do for you? (Skill: Acknowledging the concern and asking about Expectations.)
Patient: I was just hoping you could give me a tablet, like my dad had, to get it sorted so I can get back to normal.
GP: Okay. Thank you, that makes perfect sense. Can I try and pull all this information together and explain what I think is going on? (Skill: Summarising and asking permission to explain, which promotes a patient-centred approach.)
Patient: Alright.
GP: You came in thinking this was likely Type 2 diabetes, similar to your father’s. And given your age and family history, that’s a very reasonable thought. However, there are a few things that point in a different direction. The fact the symptoms came on quite quickly, the weight loss that you weren’t trying for, and especially the ketones that the nurse found in your urine, all strongly suggest that the diagnosis is actually Type 1 diabetes. (Skill: ‘Chunk and check’ approach. Acknowledging the patient’s idea first before presenting the likely diagnosis.)
GP: In simple terms, Type 2 diabetes is about the body not responding well to the insulin it makes. Type 1 is different; it’s an autoimmune condition where the body stops producing insulin altogether. Insulin is the key that lets sugar from our blood get into our cells for energy. Without it, the sugar builds up in the blood, causing the symptoms you’re experiencing. Does that make sense so far? (Skill: Using a simple analogy to explain a complex medical concept.)
Patient: Type 1? But isn’t that what children get? And… does that mean I’ll need insulin? Oh god, what about my license?
GP: It’s a common myth that Type 1 only affects children; it can start at any age. And yes, because your body isn’t making its own insulin, the treatment will be to replace it with insulin injections. I know that sounds daunting, and I want to talk properly about your driving license, as I know it’s your biggest concern. (Skill: Directly addressing the patient’s concern and fear immediately after they are raised.)
GP: Because this is a new diagnosis of Type 1 diabetes, the national guidelines are very clear. I need to arrange an immediate, same-day referral for you to be seen by the specialist diabetes team at the hospital. They will confirm the diagnosis and get you started on the right treatment straight away. How do you feel about that? (Rationale: Stating the management plan clearly and seeking the patient’s input, demonstrating shared decision-making.)
Patient: The hospital? Today? It all seems a bit much.
GP: I know it’s a lot to take in. It is urgent because the ketones show your body is under a lot of strain, and the specialist team are the experts in managing this safely from the very beginning.
GP: Now, we must talk about driving. I need to be very direct here. Because your blood sugar is unstable and you’ll be starting a new treatment that can affect it, you must stop driving immediately. You also have a legal duty to inform the DVLA of your diagnosis. (Skill: Being clear, direct, and unequivocal about advice that has significant safety and legal implications.)
Patient: Stop driving? But that’s my livelihood! For how long?
GP: I completely understand this is the worst possible news for you. This is not necessarily permanent. You can reapply for your license once your blood sugar is stable and you’re confident in managing the insulin. The hospital team are experts in this; they will give you education and support to get you back on the road safely as soon as possible. (Skill: Softening the blow by providing context, hope, and a clear path forward. This directly addresses his main concern.)
GP: The last, and most important, thing we need to discuss is safety before you get to the hospital. The ketones mean there’s a risk of becoming very unwell with a condition called DKA. So, if you start vomiting, get severe stomach pain, become drowsy or confused, or if your wife notices your breathing has become deep and fast, you must call 999 or go straight to A&E. Do you understand how serious that is? (Rationale: Providing explicit verbal DKA safety netting as per the marking scheme.)
Patient: Right… yes, I understand. Vomiting, stomach pain, confusion. Got it.
GP: Excellent. So, just to summarise the plan. I am going to call the hospital diabetes team right now while you’re here to arrange for you to be seen today. We’ve agreed on the crucial importance of not driving for now and informing the DVLA. And you know the urgent warning signs to look out for. I’ll also send you a text message with those safety-netting points written down. I’ll then give you a call in a couple of days just to check in and see how you’re getting on. How does that sound as a plan? (Skill: Summarising the plan, confirming understanding, and arranging follow-up.)
Patient: It’s… a lot. But… okay. I understand what I need to do.
GP: It is a huge amount to take in, David, and we’re here to support you. Let’s make that call to the hospital together now.
