A patient pathway is the route taken by patients from referral until treatment completion.  Such pathways are used to manage the quality and effectiveness of healthcare delivery. However, patient pathways are often complex from a patient’s perspective and substantial variability exists across conditions. Furthermore, poor patient flow may increase the likelihood of harm and raises healthcare costs.

Much interest has arisen around the use of portable communication devices such as smartphones and related apps, in enhancing healthcare delivery and support. Such technologies have become ubiquitous amongst both patients and healthcare professionals.

Focusing on the bariatric surgical pathway initially, we have developed the Usher platform. Usher is a smartphone app that provides tailored education and support to patients referred to the Imperial Weight Centre for bariatric surgery. The app has been developed collaboratively by a team of clinicians, academics, and designers and is underpinned by end-user research with patients and clinicians, and a user-centred approach to development. Usher provides bariatric patients with information about their condition and available treatment options, tests their knowledge, allows users to track their health, and provides an overview of the entire bariatric pathway. Direct communication between patients and clinicians is also supported.
