Nurses have been warned to ensure diabetes patients know how to insert pre-filled insulin cartridges correctly into a type of insulin pump in order to avoid the risk of hyperglycaemia.
Patients using a particular type of pump have been inserting cartridges incorrectly, leading to leaks and under-delivery of insulin, said the Medicines and Healthcare products Regulatory Agency.
The products in question are the Accu-Chek Insight insulin pump system and NovoRapid PumpCart cartridges.
The MHRA said it had issued a medical device alert after feedback to the manufacturer, Roche Diabetes Care, from patients who were experiencing leaking insulin cartridges.
It noted that patients could check for any leaked insulin in the cartridge compartment by regularly checking the pump a few hours after changing the cartridge as any leaked insulin would be visible.
Diabetes departments and all healthcare workers responsible for patients who use the devices have been advised to take action over the alert.
They should identify users of the Accu-Chek Insight insulin pump system and ensure they receive the manufacturer’s field safety notice, including the Accu-Chek Insight Training Chart.
In addition, they should ensure patients understand the problem detailed in the notice and and receive additional training on the information in the chart.
John Wilkinson, the MHRA’s director of medical devices, said: “It’s important that cartridges are correctly inserted into these pumps.”
Dan Howarth, Head of Care at Diabetes UK, added: “Ensuring the correct level of insulin is vitally important in the management of diabetes.”
