Evaluation of a new durable insulin pen with memory function among people with diabetes and healthcare professionals

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,...
