Developing medical device technologies from users' perspectives: A theoretical framework for involving users in the development process

Abstract

Objectives: To suggest an acceptable and generic theoretical framework for involving various types of users in the medical device technology (MDT) development process (MDTDP). Methods:The authors propose a theoretical framework suggesting different routes, methods and stages through which various types of medical device users can be involved in the MDTDP. Results:The suggested framework comprises two streams of users' involvement in MDT development i.e. what might be called the end users' stream and the professional users' stream for involving these two groups respectively in the process of developing both simple and more complex and innovative medical devices from conceptualisation through to the market deployment. This framework implies various methods that can be used for users' involvement at different stages of the MDT lifecycle. To illustrate the application of the framework, a number of MDT development scenarios and device exemplars are presented. Conclusions:Development of medical devices from users' perspectives requires not only the involvement of healthcare professionals but also that of the ultimate end users i.e. patients, people with disabilities and/or special needs, and their caregivers. The evidence shows that such end users quickly discard devices that do not fulfil their personal expectations, even though both manufacturers and healthcare professionals may consider those end users' requirements met. Developers and manufacturers need to recognise this potent potential discrepancy between the parties involved, and involve end users and professional healthcare staff directly in the MDTDP. The framework, the authors contend, is a step forward in helping medical device manufacturers plan and make decisions about users' involvement at different stages of the MDTDP.3

Crucial design issues for special access technology; a Delphi study

“…This research builds on a number of frameworks which have been developed over the last 15 years to guide the design of AT. Shah and Robinson [32] formulated a theoretical framework for the development of medical and assistive technologies. They concluded that two streams of user involvement are necessary to facilitate the participation of both end-users and professional users.…”

Get moving: the practice nurse is watching you!

“…This strategy was based on several existing models for the design of medical devices ( Figure 2). [10][11][12] From November 2010 to September 2012 we conducted three substudies: (A) a user requirements study, (B) a usability test of the system in a laboratory situation and (C) a pilot study in two practices.…”

“…Especially, the involvement of the end users produces good results in assailable evaluation tasks like tested before [5,[21][22][23]. In this group, think-aloud analysis and questionnaires are suitable methods.…”
