Analysis of "Dose Accuracy and Reliability of a Connected Insulin Pen System"

In an article in the Journal of Diabetes Science and Technology, Backfish and coauthors examined the dose accuracy and reliability of the Tempo Pen and Tempo Smart Button connected insulin pen system. This study sponsored by Eli Lilly and Company found that this system met the International Organization for Standardization 11608-1:2014 requirements for dose accuracy at a range of doses, as well as the data transfer requirements after all injections. While these results are very encouraging, they were based on simulated human factors data while data from a human factors validation study where individuals successfully dialed and administered correct doses was not reported. There is a need for further studies in a variety of populations that would greatly benefit from this enhanced insulin pen technology to facilitate optimization of dose adjustments based on accurate and reliable insulin dosing data.
