GMG ArcData will create a mobile-based application to improve communications and data exchange among patients and navigators involved in new pancreas surgery oncology episodes of care. Functionality will align with care processes using smartphone and the EHR patient portal. We will apply user-centered design theory and behavioral psychology approaches to co-design, develop, and test usability of features that optimize patient navigators-patient encounters on scheduling issues, nutrition guidance, pain management, wellbeing assessments, and activity tracking. Evaluation endpoints will reflect how the application improves the efficiency of workflows and lessens cognitive burden. We will assess how patients and navigators perceive the tool’s ability to provide more control and easier access to information about surgical care. The key project innovations are based on Fast Healthcare Interoperability Resources (FHIR)-based engineering standards that enable interoperability among digital health platforms, apply ‘recommender’ functions based on similar patients’ experiences, and exploit microeducation tools to enhance patient understanding about their surgical care. We have partnered with MedStar Health and Georgetown University Lombardi Comprehensive Cancer Center to co-design the software and access patients for usability testing. Successful implementation will lead to exploring a joint venture for scaling to other care episodes, expanded functionality, and co-creating business models for commercialization.
