The Advantages of Using a Two-Arm Crossover Study Design to Establish Proof of Concept of Technology Interventions: The Case of a Mobile Web-Based Reporting of Glucose Readings in the Management of Gestational Diabetes Mellitus (GDM)

This chapter serves to illustrate the benefits of using a two-arm crossover study design to test the usability and fidelity issues and establish proof of concept for an innovative technology solution for a clinical context. Specifically, a pilot study is conducted to identify the potential benefits of utilising mobile web-based reporting of glucose readings in the management of gestational diabetes mellitus (GDM). Such an approach is suggested to be suitable to trial technology solutions in healthcare contexts.
