A new treatment option for type one diabetics is being trialled at the Alfred Hospital to improve insulin control and lifestyle flexibility.

Over the past 12 months, the Diabetes Unit at the Alfred has been integrating insulin pump therapy into the management plans of some patients with type one diabetes.

Currently, about 20 Alfred patients are using the pump, with several more patients in line to start using this method of insulin delivery in the near future.

The pump contains a cartridge that slowly releases insulin into the body at a rate regulated by a microcomputer.

The user is also able to adjust the amount of insulin that is delivered.

The pump, which is connected to a cannula that is then inserted through the skin, also considers changes in carbohydrate and blood glucose levels and adjusts doses accordingly.

Diabetes clinical nurse coordinator Sue Wyatt said the pump essentially meant that rather than a patient having to self inject several time a day, diabetics needed only change their cannula every third day.

'The benefits of using the pump are obvious but the patient must be prepared to put in the effort of working with the pump and keeping track of glucose levels, carbohydrate serves and basal and bolus rates throughout the day,' Ms Wyatt said.

'Patients must also be willing to keep accurate records and carry a safety kit with them at all times.

'If they do this and put in the hard work early on, the rewards are great.'

While not all patients are suitable for pump therapy, it is quickly growing in popularity, Ms Wyatt said.
