Patient’s Story (Role-Player Brief)

You are Sarah Carter, Leo’s mother. You are a single parent and work full-time as a care assistant, often doing extra shifts. You’re calling about your 7-year-old son, Leo.
Presenting Complaint: For the last 3-4 weeks, Leo has been absolutely exhausted. He has no energy to play football after school, which he usually loves. He’s also been drinking huge amounts of water and juice, and as a result, he’s constantly needing the toilet. This has become a problem at school, and he’s even started wetting the bed a couple of times a week, which hasn’t happened since he was a toddler. You’ve noticed his clothes seem a bit loose on him recently.

Key Information (Reveal only if asked directly):
• Weight Loss: If asked specifically, you’ll say you haven’t weighed him, but his school trousers definitely look baggier.
• Diet: He has a sweet tooth and you’ve been letting him have more sugary drinks lately because you’ve been too tired to argue after long shifts.
• Illness: He hasn’t had a fever or complained of any pain when he wees. He seems well otherwise, just very tired.
• Family History: Your father (Leo’s grandfather) has Type 2 diabetes.
ICE (Ideas, Concerns, Expectations):
• Ideas: “I think it’s probably another urine infection. He had one a couple of years ago and was drinking a lot then too. Or maybe it’s just a phase because he’s having a growth spurt.”
• Concerns: “My main worry is the school. They’ve called me twice about him needing the toilet all the time during lessons, and I’m worried they think I’m a bad parent. I can’t afford to take much time off work if he needs to see a specialist.”
• Expectations: “I was hoping you could give him some antibiotics for the urine infection so we can get it cleared up quickly.”

Psychosocial Context: You are a single mother to Leo and his older sister (age 11). You work long hours as a care assistant and are financially stretched. You feel overwhelmed and guilty that you haven’t brought Leo in sooner.

Role-Play Instructions: Initially, you are focused on the idea of a UTI. If the doctor suggests it might be diabetes, become visibly anxious. Express your worry about managing a long-term condition and the impact on your work. If the doctor explains the need for a same-day hospital referral clearly and empathetically, you will agree, but only after voicing your practical concerns.

Data Gathering & Diagnosis

Phase 1: Open the Consultation & Explore the Presenting Complaint Rationale: To establish rapport and understand the core symptoms (the classic ‘4 Ts’ of Type 1 Diabetes) from the parent’s perspective.

• Key Questions:
o “Tell me more about the tiredness. What’s his energy like compared to a month ago?” (Characterises lethargy)
o “You mentioned he’s drinking a lot. How much would you say he’s drinking in a day?” (Quantifies polydipsia)
o “And how has that affected his toileting? How often is he going during the day? You mentioned bedwetting?” (Characterises polyuria and secondary nocturia)
o “Have you noticed any changes in his weight recently? How are his clothes fitting?” (Screens for weight loss – the ‘Thinner’ T)
o “When did you first notice these changes starting?” (Establishes timeline)

Phase 2: Broaden the Differential & Screen for Red Flags Rationale: To safely exclude common differentials like a UTI and, critically, to screen for signs of Diabetic Ketoacidosis (DKA), which is a medical emergency.

• Key Questions (Differentials):
o “Does he complain of any pain or stinging when he passes urine?” (Screens for UTI)
o “Has he had a high temperature, or seemed unwell with a fever?” (Screens for infection)
o “Has he complained of any tummy pain?” (Common symptom in both UTI and DKA)
• Key Questions (Red Flags for DKA):
o “Has he been sick or felt nauseous at all?” (Vomiting is a key DKA symptom)
o “Have you noticed any changes in his breathing? For example, is he breathing more deeply or faster than usual?” (Screens for Kussmaul respiration)
o “How is he right now? Is he drowsy, sleepy, or confused?” (Assesses for reduced consciousness level, a late sign of DKA)

Phase 3: Build the Clinical Context Rationale: To gather relevant past medical, family, and developmental history to support the working diagnosis.

• Key Questions:
o “Has Leo had any serious illnesses in the past? You mentioned a urine infection before?” (Checks relevant PMH)
o “Is there any history of diabetes in your family?” (Identifies genetic predisposition)
o “How is his general development and progress at school, aside from these recent issues?” (General developmental screen)

Phase 4: Understand the Patient’s Perspective & Impact Rationale: To conduct a holistic consultation by exploring the parent’s fears and the psychosocial impact, which is essential for agreeing on a management plan.

• Key Questions:
o “What have you made of all this? Do you have any thoughts on what might be causing these symptoms?” (Probes Ideas)
o “What is your biggest worry about all of this at the moment?” (Probes Concerns)
o “What were you hoping I might be able to do for Leo today?” (Probes Expectations)
o “How has this been affecting you and your family life? You mentioned work is a concern.” (Explores psychosocial impact)
Working Diagnosis:
• Most Likely: New-onset Type 1 Diabetes Mellitus.
• Important Differentials: Urinary Tract Infection, Diabetic Ketoacidosis (DKA).

Diagnosis & Explanation Script
“Sarah, thank you for explaining everything so clearly. I know you were worried this might be another urine infection, and it’s a very reasonable thought given the symptoms. However, the combination of being very thirsty, passing lots of urine, the tiredness, and losing weight makes me concerned about something different. I suspect Leo might have Type 1 diabetes. This is a condition where the body stops producing insulin, a hormone we need to get energy from food. It is not caused by anything you have or haven’t done. The most important thing now is to get this confirmed and start the right treatment straight away.”

Management
Collaborative Management Plan

1. Address ICE & Agree on Goals:
o “I know you were hoping for antibiotics for a urine infection, but the symptoms point much more strongly towards diabetes, which needs a different and more urgent approach. Our priority today is to get a definite diagnosis and get Leo seen by the specialist team who can start helping him feel better immediately. Does that sound like a reasonable plan?”

2. Offer Investigations & Referrals:
o Urgent Action: “To get a better idea, I would normally arrange a finger-prick blood sugar test here, but given the strong symptoms, the safest and quickest thing to do is to speak to the hospital’s children’s diabetes team right now.”
o Referral (Urgency: Same-day/Immediate): “I am going to call the specialist paediatric diabetes team at the hospital immediately. They will need to see Leo today to confirm the diagnosis and start treatment. This isn’t something that can wait. I understand your concerns about work, but this is a medical priority for Leo’s safety.”

3. Collaborative Treatment Planning (Medication & Lifestyle):
o Initial Advice: “While we arrange the hospital admission, it’s important that you don’t restrict his drinking—let him drink as much water as he wants. Avoid any more sugary drinks for now.”
o Empower Parent: Provide the parent with a contact number for the paediatric assessment unit and explain what to expect on arrival (blood tests, meeting the diabetes team).

4. Explicit Safety Netting & Contingency Planning:
o “You need to take Leo to the hospital’s children’s department straight after this call. I will phone them now to let them know you are on your way.”
o Urgent DKA Safety Net: “If, on the way to the hospital or at any point, Leo starts vomiting, complains of tummy pain, becomes very drowsy, or you notice his breathing seems deep or fast, you must call 999 for an ambulance immediately as this would be an emergency.”

5. Summarise, Check Understanding & Agree on Follow-Up:
o Summary: “So, to recap, the plan is for you to take Leo to the children’s ward at the hospital right now. I will call ahead for you. This is to test for Type 1 diabetes. Don’t worry about work for now; the hospital can provide any letters you need. This is the most important thing for Leo’s health.”
o Follow-up: “The specialist team will take over his care, but our practice will be here to support you all long-term. Please let us know once you have been seen and have a plan.”
