OBJECTIVE: FlexTouch® (FT; Novo Nordisk A/S, Bagsvaerd, Denmark) is a new prefilled insulin pen that has no push-button extension and low injection force. This multi-centre, crossover usability study evaluated the perceptions of, and preference for, FT versus another widely used prefilled pen, SoloStar® (SS; Sanofi, Paris, France), by people with diabetes and healthcare professionals. RESEARCH DESIGN AND METHODS: Following instruction, participants performed injections into a foam cushion, randomly alternating between doses of 20, 40 and 80 international units (IU). Participants then answered questions on usability and preference. RESULTS: In all, 59 people with diabetes and 61 healthcare professionals (30 physicians and 31 nurses) took part. Overall, significantly more respondents preferred to use FT than SS (83 vs 10%, respectively), found FT easier to use (83 vs 9%) and would recommend FT to others (83 vs 8%; p < 0.001 for all). More respondents found it 'very/fairly easy' to reach the push-button and to inject 20, 40 and 80 IU with FT (93, 90 and 88% to inject, respectively) than with SS (73, 43 and 15% to inject, respectively; p < 0.001 for all). Most respondents chose FT as giving them the most confidence in correct and complete insulin delivery (76 vs 6%; p < 0.001) and considerably more were 'very/rather confident' in managing their daily insulin injections with FT than with SS (88 vs 58%). CONCLUSIONS: Most participants rated FT as easier to use and to inject with, were more confident in its accuracy of insulin delivery and preferred it to SS.
