The role of nurse case managers (NCM) involves a rarely visible emotional labor, even more when their role focuses on the care of elders at risk (EAR). Motivated by the lack of qualitative research on the emotional universe of NCM, this study explores the emotional universe (EU) of NCM regarding the care they provide to EAR in primary health care as well as the reasons that generate these emotions. An interpretative–phenomenological approach was implemented in southern Spain, with a purposive sampling that included nurses playing the NCM role for at least three years. Data collection was conducted in two periods (between September 2019 and July 2022). The primary collection tool was the semi-structured individual interview, with starting categories based on Bisquerra’s EU taxonomy. The analysis followed Ricoeur’s considerations, using the Nvivo software. In the NCM’s EU, the recognition of the social phenomena stands out, with an open feeling of empathy regarding the desire of the EAR to continue living at home. However, there was also helplessness, resignation, disappointment, and frustration when EAR rejected their proposals. Furthermore, the system’s limitations aroused compassion in the NCM and made them go beyond the limits of their role. This EU requires that their role be valued more, and higher responsiveness must be enforced to improve EAR care.
