The Cold Chain Question
You work in a community pharmacy that dispenses and sells temperature-sensitive products. A deliveries driver hands you a carton of insulin pens at 2:15 pm. The carton's data logger strip shows the temperature exceeded 8°C for about 40 minutes during transit, peaking at 11°C. The pens are normally stored at 2–8°C. The driver says, "It's probably fine, just put it in the fridge." The dispensary fridge is at 5°C and has space. A patient is due to collect one of these pens at 4 pm. The pharmacist is off-site at a meeting until 3:30 pm. Your store's procedure says any cold-chain excursion must be referred to a pharmacist before the stock is accepted into the dispensary fridge.
1. Should you put the pens in the fridge? Explain your reasoning.

No - not yet. The procedure says an excursion must be referred to a pharmacist before the stock enters the dispensary fridge, and the data logger shows a real excursion (above 8°C for about 40 minutes, peaking at 11°C).
Putting the pens in the fridge would:
- breach the store procedure;
- mix potentially affected stock with good stock, making it hard to quarantine later;
- risk the patient receiving a product whose stability may be compromised.
Correct action: quarantine the carton - keep it segregated, labelled "Do not dispense - cold-chain excursion - awaiting pharmacist review" - and store it according to the manufacturer's instructions for an excursion if known, or leave it in a controlled area. Record the logger reading, time, driver name, and carton details. Do not accept it into the dispensary fridge.
2. The patient arrives at 4 pm and the pharmacist has reviewed the stock. What should happen, and what would you tell the patient?
Read the worked answer
The pharmacist's review decides the outcome - you do not decide it.
If the pharmacist rejects the affected carton:
- The patient's pen must come from unaffected stock or be reordered.
- Tell the patient honestly: "The delivery didn't meet our temperature requirements, so we're not dispensing from it. We can supply from another batch / have it ready by [time]."
- Offer to call when it is ready; do not let the patient leave without a clear plan.
If the pharmacist accepts it (for example, the manufacturer's data supports short excursions):
- Dispense per the pharmacist's instruction and record the decision.
Never tell the patient "it's probably fine" - that is a clinical assurance you cannot give. Your role is accurate handover, quarantine discipline, and clear communication.
