The usability of two types of insulin delivery devices (HumaPen® Luxura and NovoPen® 300) was evaluated using a clinical questionnaire and a basic test. The objective of this study was to provide important information to diabetic patients who are going to start insulin therapy using these devices. The clinical questionnaire was given to 30 inpatients with diabetes in the diabetes center of our hospital by a crossover method. The basic test targeted the following items : font size of dose number, interdigitation torque required to load cartridge into pen body, depression of the injection button, injection force, and volume of click.
According to the results of the clinical questionnaire, HumaPen® Luxura was significantly easier to use in terms of set up, visibility of dose number, ease of correcting dose, ease of depressing injection button, and ease of replacing pen cap than NovoPen® 300. The results of the basic test revealed that dose number of HumaPen® Luxura was slightly larger than that of NovoPen® 300 and the injection force was lower. Though the volume of click for HumaPen® Luxura was smaller than that of NovoPen® 300, it was larger than that of HumaPen® Ergo. The interdigitation torque needed to load a cartridge into the pen body of HumaPen® Luxura was about 3 times that of NovoPen®300.
In conclusion, HumaPen® Luxura is the most suitable device for patients of all ages because of its ease of use in all operations from set up to injection. NovoPen® 300, on the other hand, is suitable mainly for younger patients because of the difficulty in correcting the dose and the large injection force as compared with HumaPen® Luxura, despite its better portability.
