The Gold score is a simple 1-question tool used to assess awareness of hypoglycaemia in adults with type 1 diabetes. NICE recommends using the Gold score or Clarke score to quantify hypoglycaemia awareness at review.

📋 Gold Score Question

“Do you know when your hypos are commencing?”

Score	Meaning
1	Always aware of hypoglycaemia starting
2	Usually aware
3	Borderline / uncertain awareness
4	Reduced awareness begins to become clinically significant
5	Often unaware
6	Usually unaware
7	Never aware of hypoglycaemia starting

📊 Interpretation

Gold score	Interpretation
1–2	Normal hypoglycaemia awareness
3	Borderline awareness
≥4	Impaired awareness of hypoglycaemia

⚠️ Why It Matters

Impaired hypoglycaemia awareness means the patient has reduced ability to recognise early warning symptoms of low glucose.
It is associated with a significantly increased risk of severe hypoglycaemia.
Severe hypoglycaemia may cause confusion, collapse, seizure, injury, coma or need for help from another person.
It can affect driving, work, quality of life and treatment safety.

🧠 Symptoms of Hypoglycaemia

Autonomic / adrenergic symptoms	Neuroglycopenic symptoms
Sweating, tremor, palpitations, hunger, anxiety, tingling.	Confusion, drowsiness, irritability, slurred speech, poor concentration, visual disturbance, seizure or reduced consciousness.

🛠️ Management if Gold Score ≥4

Review recent hypoglycaemia frequency, timing, triggers and severity.
Check insulin doses, carbohydrate counting, alcohol intake, exercise patterns and injection technique.
Reinforce structured education in flexible insulin therapy.
Prioritise avoiding hypoglycaemia and review glucose targets if they are too low.
Consider diabetes technology such as real-time continuous glucose monitoring or insulin pump therapy where appropriate.
Ensure the patient has rapid-acting carbohydrate available and knows how to treat hypos.
Discuss driving safety and DVLA rules where relevant.
Refer to the specialist diabetes team if recurrent severe hypoglycaemia persists despite optimisation.

🚗 Driving and Safety

Hypoglycaemia awareness is important for driving safety.
Patients should check glucose before driving and avoid driving if hypoglycaemic or at risk of hypoglycaemia.
Recurrent severe hypoglycaemia or impaired awareness may require DVLA advice and specialist review.

🧠 Exam Pearls

The Gold score is a single-question score for hypoglycaemia awareness.
Question: “Do you know when your hypos are commencing?”
It is scored from 1 to 7: 1 = always aware, 7 = never aware.
Gold score ≥4 suggests impaired awareness of hypoglycaemia.
NICE recommends assessing hypoglycaemia awareness annually in adults with type 1 diabetes.

✅ Key message: A Gold score of 4 or more identifies impaired hypoglycaemia awareness and should prompt review of insulin therapy, education, technology options and safety advice.
