Personal information and public health: Design tensions in sharing and monitoring wellbeing in pregnancy

Highlights • Sharing personal data in public health is very different from the closed-circle of personal data use.• Sharing data has both pragmatic (time, workload etc.) and psychosocial (confidence, competence, connectedness etc.) implications for care.• Health professionals must balance care for the individual against the wellbeing of the patient population.• Women prefer reflective and conversational, rather than directive or transactional, feedback.• Designers are advised to focus on strategies to support negotiation, navigate uncertainty, and realise a shared practice of wellbeing.
