Hypoglycaemia Management in a 71-Year-Old Woman

Practise this PLAB 2 counselling station on Hypoglycaemia. 8-minute voice AI simulation with feedback on all 3 marking domains.

Clinical scenario

You are an FY2 doctor in a GP surgery. Mrs Olivia Knowles, a 71-year-old woman with type 2 diabetes on insulin therapy, has experienced two episodes of severe hypoglycaemia in the past month. She is frightened and unsure how to recognise and manage hypoglycaemic episodes. Please counsel her on recognising hypoglycaemia symptoms, management strategies including use of glucagon, and adjustments to her insulin regimen to prevent future episodes.

Background notes: PMH: Type 2 DM, Hypertension, Osteoarthritis knees, Mild hearing loss, Cataracts (managed)

What this station tests

  • Identifying precipitants of hypoglycaemia: missed meals, excess insulin, renal impairment prolonging insulin action
  • Age-appropriate glycaemic targets: relaxing HbA1c target to 53-58 mmol/mol in elderly insulin users to reduce hypo risk
  • Teaching the hypo rules: fast-acting glucose, followed by long-acting carbohydrate, glucagon for severe episodes
  • Safety assessment for a patient living alone: nocturnal hypos, personal alarm, family access, glucagon training
  • Insulin dose adjustment as the primary intervention: reducing the dose, not just educating about recognition

Consultation approach

The opening

Hypoglycaemia counselling in an elderly insulin-dependent patient is about safety, not just education. The candidate must identify the cause, teach recognition and treatment, and assess whether the patient can safely manage insulin at home alone. Mrs Knowles is 71, on insulin, has had two severe hypos in a month, lives alone. She is terrified. Open with: 'Mrs Knowles, those episodes must have been very frightening. Tell me what happened during each one.' Start with her experience, not the physiology.

Core approach

Explore each episode. First: mid-afternoon while gardening, had skipped lunch. Became shaky, confused, could not remember where she was, called her son in panic. He gave her juice. Second: nocturnal, woke confused and sweating, managed to call 999, paramedics found very low blood glucose. Both episodes had identifiable precipitants: missed meal and likely excess insulin relative to intake.

Identify the cause. Review her insulin regimen: type, dose, timing, injection technique. Is her dose appropriate for her current eating pattern? Is she adjusting for missed meals? Check HbA1c: if too tight (below 48 mmol/mol in a 71-year-old on insulin), overtreatment is the problem and targets should be relaxed. Age-appropriate targets are 53 to 58 mmol/mol for elderly patients on insulin to reduce hypo risk. Check renal function: CKD prolongs insulin action.

Teach the hypo rules. Recognition: shaking, sweating, confusion, hunger, irritability, visual changes. Treatment: fast-acting glucose immediately (glucose tablets, juice, non-diet fizzy drink), followed by long-acting carbohydrate (biscuit, sandwich). If unable to swallow: glucagon injection (does she have one? Does she know how to use it? Does her son?). She lives alone: who helps during a nocturnal hypo?

Assess safety. She is 71, lives alone, has had a nocturnal hypo severe enough to require paramedics. This is a patient safety concern. Does she have a personal alarm? Does her son have a key?

Closing and safety netting

Practical plan: review and likely reduce insulin dose (relaxing HbA1c target to prevent further hypos). Ensure she has glucose tablets by her bed and in her handbag. Prescribe glucagon kit and arrange for her son to be trained in its use. Regular meal timing: never skip meals on insulin. Home blood glucose monitoring before bed (if below 6 mmol/L, have a snack).

Address her fear: 'These episodes are preventable with the right adjustments. We are going to reduce your insulin dose so this is much less likely to happen.' Safety net: 'If you feel the warning signs, act immediately. Do not wait to see if it passes. If you find her confused or unresponsive, her son should use the glucagon and call 999.' Consider referral to diabetes specialist nurse. Follow-up in 1 to 2 weeks after dose adjustment.

How examiners mark this station

Examiners will assess your ability to explain hypoglycaemia and its management in a patient-centred way. Domain 2 (Clinical Management) and Domain 3 (Interpersonal Skills) are equally weighted and primary. Expect marks for accurate information delivery, shared decision-making, chunk-and-check technique, and addressing the patient's specific concerns. Domain 1 (Data Gathering) is assessed through how well you establish the patient's baseline understanding and elicit their concerns.

Domain 1: Data Gathering, Technical and Assessment Skills (Primary focus)

Scores well: Each episode explored with precipitant identified. Insulin regimen reviewed (type, dose, timing). HbA1c checked against age-appropriate target. Renal function considered. Living situation assessed. Glucagon availability checked.

Costs marks: Not exploring episode details. Not reviewing insulin. Not checking HbA1c target appropriateness. Not assessing living situation.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Insulin dose reduction planned. HbA1c target relaxed. Hypo rules taught (fast glucose then slow carb). Glucagon prescribed and training arranged. Bedtime glucose checking advised. Personal alarm discussed. DSN referral.

Costs marks: Not adjusting insulin. Not relaxing targets. Not prescribing glucagon. No safety plan for living alone.

Domain 3: Interpersonal Skills (Primary focus)

Scores well: Acknowledging her fear. Providing reassurance that episodes are preventable. Empowering her with practical tools. Involving her son in the safety plan. Not being patronising about her ability to manage.

Costs marks: Dismissing her fear. Being patronising. Not involving family. Lecturing rather than empowering.

Common examiner feedback (and how to fix it)

Did not provide adequate explanation or plan to the patient

Fix: Use chunk-and-check: deliver one concept, check understanding, then move to the next. Offer all relevant treatment options with risks and benefits before helping the patient decide.

Did not sufficiently recognise or respond to the patient's feelings, concerns, or expectations

Fix: Before and during counselling, explicitly ask what concerns the patient most. Respond to emotional cues with empathic statements before continuing with information.

Common mistakes in this station

  1. Not reviewing the insulin dose. The most effective intervention is reducing the insulin to prevent further episodes. Candidates who teach hypo recognition without adjusting the medication that caused the problem miss the primary intervention.
  2. Not relaxing the HbA1c target. In a 71-year-old on insulin, an HbA1c below 48 mmol/mol is dangerously tight. Age-appropriate targets allow looser control to prevent hypoglycaemia. Candidates who pursue tight targets in elderly patients cause harm.
  3. Not assessing the safety of living alone. A nocturnal hypo in a 71-year-old who lives alone is a serious safety concern. Candidates who counsel about glucose tablets without addressing the living situation miss the patient safety issue.

Resitting PLAB 2?

If counselling stations have been a challenge, the most common issue is information overload: delivering too much clinical detail without checking understanding. Practise the chunk-and-check technique until it becomes automatic. Remember that shared decision-making, not lecturing, is what scores highly in Domain 3.

Example opening

Hello, my name is Dr [Name]. I understand you've come in today to discuss [topic]. Before I explain things, could you tell me what you've been told so far, so I know where to start?

Frequently asked questions

How do I open and run a hypoglycaemia counselling station in PLAB 2?

Hypoglycaemia counselling in an elderly insulin-dependent patient is about safety, not just education. The candidate must identify the cause, teach recognition and treatment, and assess whether the patient can safely manage insulin at home alone. Mrs Knowles is 71, on insulin, has had two severe hypos in a month, lives alone.

What does a strong performance look like to the examiner in this station?

Strong performances show: Each episode explored with precipitant identified. Insulin regimen reviewed (type, dose, timing). HbA1c checked against age-appropriate target. Renal function considered. Weak performances: Not exploring episode details. Not reviewing insulin. Not checking HbA1c target appropriateness. Not assessing living situation.

What is the biggest pitfall in this hypoglycaemia station?

Not reviewing the insulin dose. The most effective intervention is reducing the insulin to prevent further episodes. Candidates who teach hypo recognition without adjusting the medication that caused the problem miss the primary intervention.

How should I prepare for hypoglycaemia if I have never seen it in practice?

This station rewards process over personal experience. The skill being assessed: Age-appropriate glycaemic targets: relaxing HbA1c target to 53-58 mmol/mol in elderly insulin users to reduce hypo risk. Use the domain breakdown on this page to target your preparation, then practise the station aloud so your structure survives exam pressure.
