Introduction: Patient centred care fosters a holistic approach of care switching the focus from a disease perspective to a patient's experience perspective. Patient centred care is of particular importance in the context of paediatric emergency medicine. Indeed, parents entering a paediatric emergency department (PED) are usually under stress caused by their children's illness, the unfamiliar setting of the PED and delays of care. All these factors can deteriorate their experience as well as the relationships between healthcare providers, the patients and their parents.

Methods: We explore potential areas to improve the patient experience during his journey into PED. The dimensions of the picker's patient centred care are used to guide observations, conduct interviews and focus groups. The areas of improvement are then operationalized through their translation into app functionalities.

Results: Our novel application allows supporting users on 7 of the 8 dimensions of picker's patient centred care model. The app supports parents in their decision-making to consult a PED, it provides relevant medical information to avoid unrealistic expectations and accompany the family after discharge thanks to tailored information sheets about diagnostics.

Conclusion: Our mobile app allows to make a big step toward the improvement of the patient-caregiver relationship. The direct benefits will be shared by patients and caregivers, as well as the institution.
