ABSTRACT

Objective: SoloSTAR* (SR) is a new pre-filled insulin pen device for administration of insulin glargine and insulin glulisine. This article reports on the usability of SR, as reported by healthcare professionals (HCPs) and participants, in clinical practice in Australia.

* This article is based on the outcomes of a Working Group meeting convened 18 April 2008, by the European Society on Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO), in Cannes, France. The Working Group was co-ordinated by Prof. Steven Boonen

† SoloSTAR is a registered trade name of sanofi-aventis, Paris, France

Methods: Individuals with Type 1 or Type 2 diabetes were eligible for this 3-month observational survey. Participants were supplied with the insulin glargine SR pens, the instruction leaflet and a toll-free helpline number. Training was offered to all participants. Independent telephone interviews were conducted with participants and HCPs after 6–10 weeks of use of SR.

Results: Overall, 150 HCPs across 93 sites supported this survey. Of these, 65 HCPs (14 doctors; 51 diabetes educators, covering 1669 patients) provided feedback, with the remaining 85 HCPs not responding. All HCPs rated participant training as ‘very easy’ or ‘easy’, and most reported that SR had, in their opinion, made training easier (85%) and quicker (98%). Most of the 536 participants reported that ease of learning to use (98%), ease of using (98%) and features (≥ 89%) of SR were ‘excellent’ or ‘good’. SR had positive impacts on various psychological aspects for people with diabetes, including helping overcome reluctance to use insulin, and increasing confidence in their ability to manage their diabetes using insulin.

Conclusions: In this non-randomized, non-interventional, open-label, observational survey of clinical practice, HCPs reported that SR was easy to teach and easy to use for people with diabetes. People with diabetes reported that SR was easy to use and rated specific features of SR highly. Further follow-up surveys and comparative studies in clinical practice are needed to confirm these findings and to determine the impact of SR in diabetes management.
