[SUMMARY] Since community-based medical care is promoted as part of the development of community-based integrated care systems, acute care hospitals must provide high-quality discharge support within a short time. This study aimed to examine the discharge support provided by a primary nurse (PN) in an acute care hospital. The nursing care support provided by the PN (the first author) to five patients and their families, identified during admission as candidates who would need discharge support, was analyzed. Discharge support was performed following the nursing care provision policy defined in this study. The provision of nursing care support̶both action and intention̶was described in detail. Using qualitative inductive analysis, ten themes were extracted, including “considering patients as the only ones who manage their daily lives, and always actively focusing on the personhood inherent in everyday life”; “understanding and addressing patients’ potential needs so that their stay in the hospital is comfortable, and they are prepared for discharge”; and “integrating one’s own awareness with the multifaceted perspectives afforded by information exchange with patients and diverse professionals to better understand patients’ health conditions and perceptions.” As patients’ status improved and discharge approached, the PN deepened the relationship of trust with patients through dialogue about their daily life situations. Furthermore, by sharing and complementing patients’ true intentions and needs, drawn from relationships with different professionals, nursing care was provided to realize patient-centered discharge support.
