Patients Prefer Pens With Auditory and Sensory Confirmation
Because people with diabetes sometimes suffer from visual impairment as well as reduced manual dexterity, Japanese researchers assessed the reliability of dose selection and setting of five insulin devices by patients using auditory and sensory confirmation.
A total of 48 patients (30 men, 18 women) were randomized to test the following pen devices:
- NovoPen 3 (Novo Nordisk)
- HumaPen Ergo (Eli Lilly)
- Humalog Pen (Eli Lilly)
- InnoLet (Novo Nordisk), and
- FlexPen(Novo Nordisk)
The researchers found that “Significantly more patients detected an auditory confirmation of dose setting when using the NovoPen 3 compared with the Humalog Pen, HumaPen Ergo and InnoLet.”
They add that the audible click for the FlexPen was also heard by more patients than for the Humalog Pen and HumaPen Ergo.
All patients found that the FlexPen provided the most physical sensory confirmation. Patients reported having the most confidence about setting the correct dose with the NovoPen3 and the FlexPen. These two pens were also found to be the most reliable for dose setting.
Sound recordings showed that the NovoPen 3 produced the loudest clicks when setting a dose.
“The clarity of the click when setting a dose on an insulin delivery device can affect the patient’s confidence in selecting the correct dose,” the researchers say.
