Understanding patient preferences for handheld autoinjectors versus wearable large-volume injectors.

Objective: While interest in the use of wearable large-volume injectors for subcutaneous drug delivery is increasing, it remains unclear whether and under what conditions these emerging dosing options are preferred over more frequent but shorter administration of smaller doses using handheld autoinjectors. Therefore, the objective of this study was to examine the characteristics of patients diagnosed with cancer, diabetes, inflammatory and cardiovascular diseases, and treatment attributes that determine device preferences.

Methods: Based on a cross-sectional online choice experiment, 191 participants expressed their preferences without being physically exposed to the devices or performing injections.

How to prevent medication errors: a multidimensional scaling study to investigate the distinguishability between self-injection platform device variants.

: The importance of subcutaneous drug delivery using self-injection devices based on common device platforms continues to grow. The resulting broad adoption of potentially look-alike or similar devices, however, raises concerns over limited device distinguishability and ensuing risk of medication errors. The objective of the study is thus to understand whether and how users effectively distinguish between self-injection device variants.
