Abstract
OBJECTIVES
The aim of the study was to evaluate durable insulin pens among people with diabetes (PwD) and healthcare professionals (HCPs), by comparing two durable insulin pens with memory function: NovoPen® 5 (NP5) and HumaPen® Memoir™ (HPM), and two durable insulin pens without memory function: HumaPen Luxura® (HPL) and ClikSTAR® (CS).
RESEARCH DESIGN AND METHODS
This cross-over, multicentre usability test was conducted in China, Germany and the UK. Participants evaluated all four pens in randomised order by performing handling and usability tasks related to everyday use during a face-to-face interview. Tasks, pens and preferences were rated by completing a questionnaire comprising of rating and open-ended questions.
RESULTS
NP5 was preferred by 51% of participants compared with HPM (22%, p < 0.01), HPL (12%, p < 0.01) and CS (15%, p < 0.01). Participants preferred the design of NP5 (in particular, appearance, length and robustness). Memory function for the two pens was rated equally by participants, but 54% of PwD rated NP5 as 'very easy' to learn to use versus 22% for HPM and significantly more HCPs found it 'very easy' to teach patients to use NP5 versus HPM (6-point rating scale; difference in mean score, p < 0.01). Substantially, more PwD would be confident in using NP5 (64%) compared with HPM (43%), HPL (49%) and CS (45%) (6-point rating scale; difference in mean score, p < 0.01).
CONCLUSIONS
NP5 was preferred by > 50% of PwD and HCPs. NP5 was more highly rated for design, memory function and ease of learning/teaching compared with HPM. Most PwD would be confident in using NP5 for administering daily insulin injections.
