The independent review on equity in medical devices once again highlights the multiple ways in which medical technology development can lead to solutions whereby the benefits are distributed inequitably across society, or can further exacerbate health inequalities (UK report reveals bias within medical tools and devices, 11 March). While the report is welcome, the challenge facing scientists and engineers is how to innovate medical devices differently to respond to longstanding societal biases and inequalities.
This means doing two things. First, it is essential to move beyond a superficial engagement with patients. As the report emphasises, technology development cannot be based only on the expertise of engineers or the knowledge of healthcare professionals. It needs to respond to the different social, cultural and health experiences of diverse groups of people. To be effective, this means recognising differences and actively supporting marginalised groups to represent themselves.
