Defining and characterizing task-shifting medical devices.

This study defines and characterizes task-shifting medical devices based on healthcare professionals' responses. Ease of use was identified as the most important characteristic that defines a task-shifting medical device, alongside safe and effective, and was strongly associated with enabling peer-to-peer training and maintainability. The findings from this study can be used to inform technology product profiles for medical devices used by lower-level cadres of healthcare workers in low-resource settings.
