Healthcare systems increasingly rely on digital technologies to sustain costs and improve access to quality care. Data drive a wave of automation aspiring to improve productivity by forging connections between health and wellness, medical research, and clinical decision support. Mobile apps and patient-generated data combined with provider recordings pave the way towards personalized care pathways and just-in time access to health services. Navigating the health ecosystem becomes challenging as roles and relationships change. This paper reflects on the digital health compass to navigate the health system using one's own data. Health information technology standards are at the core of the compass, to tap the potential of shared aggregate data and sustain trust. The notion of the patient summary as a window to one's health is used as an example to drive our call for action for health informatics to develop methods to calibrate the digital health compass and feed on ‘my data’, respecting ‘my decision’, to fuel ‘our ePower’.
