This report relates to the research on the benefits and the use of caring in nurses’ diagnostic practice in patient education. The theoretical framework has been built thanks to Joan Tronto’s work on caring. Caring consists of taking care of other people’s concerns and needs. This raises the issue of knowing how nurses deal with caring during the educational diagnosis. The qualitative research was centered around four nurses who were receiving patients within an educational program in a diabetes department of a Paris-based hospital. The analysis of the semi-structured and explicative interviews shows how nurses care about and take care of patients both through their thoughts and their nursing practice. Within the educational program, they set up a particular plan in order to interview patients upon their arrival. This plan, similar to a spatio-temporal ritual, tends to facilitate the clinical interview, allowing for an assessment of the emotional impact of the chronic condition on the patient’s life. This enables the making of an appropriate educational diagnosis.
