Framework for the Design of Tripartite Interactions in the Caregiver-Patient-Researcher Partnership

Overview of thesis

The patient-caregiver partnership has demonstrated its value in many therapeutic contexts, benefiting the patient's well-being and the success of the care provided. From the collaboration between the patient and the analyst to adherence to medication, this therapeutic alliance helps enhance the performance and robustness of the strategies implemented by caregivers. In the context of the Sepsis IHU, a third protagonist comes into play, essential to the research and development process in the fight against the ravages of sepsis: the researcher. In this context, they work on finding the most effective diagnostic and treatment protocol for this disease, but also the one that is easiest to disseminate and explain to patients, in the most diverse contexts, and the most sustainable to produce economically and ecologically. In the fight against sepsis, accelerating diagnosis, identifying and optimizing treatment, personalizing the therapeutic protocol, and ensuring the relevance of human-machine interfaces that enable this protocol are critical components in determining the patient's prognosis. Thus, this thesis aims to investigate the contributions of interaction design in the tripartite collaboration between caregivers, patients, and researchers emerging in the IHU project, through the design of interactive and service devices contributing to the improvement and acceleration of sepsis diagnosis and treatment:

• First, by conducting a state-of-the-art review of systems, protocols, services, and decision-making and interaction tools that drive or can accelerate this tripartite collaboration;
• Second, by engaging in design research and through design, with the aim of equipping the collaboration — modeling it, prototyping it, experimenting with it, evaluating it, and anticipating its implementation.

Finally, by observing the development process of the project, the thesis will have as its meta-objective to position the specific modalities of this Action-Design Research (ADR), within the theoretical field of human-human interaction (HHI) and human-machine interaction (HMI) design research.
