Oyster Care is the result of the search by caregivers in Flanders, Belgium, to develop quality care for patients with a Severe and Persistent Mental Illness (SPMI). This article offers a conceptual analysis of the Oyster Care model, based on experiences, analysis, and reflection of the authors, and on several examples. The starting point of the development of this new care model is the complex and difficult context of the care for SPMI patients. Their needs and suffering are very challenging on account of a wide variety of causes. At the same time they are in danger of being neglected by the care system. Paradoxically, the development and implementation of psychosocial rehabilitation in Belgian mental health care puts the care for these patients under pressure. In practice, they are often exposed to over-or undertreatment. Another aspect that has influenced the search for more qualitative care in cases of severe psychological suffering in general and palliative approaches in particular is the background of the legal regulation of euthanasia in Belgium. Oyster Care is an innovative form of the palliative approach and philosophy, tailored to the specific target group of SPMI patients. The caregivers create an "exoskeleton" or "shell" in which SPMI patients can "come to life": they are mainly dependent on the "external structure" they receive in order to function, rather than on the "internal structure" of their abilities. It is a dynamic approach that responds to the needs, possibilities and pace of each patient: within this safety, people can fold back or take new steps. Oyster Care is also a holistic care approach, based on four pillars: physical care adequately responding to the somatic impairments of these patients; psychological care changing the scope of therapy by focusing on mental comfort and wellbeing; social care providing a structure of daily activities and contacts; existential care enhancing the experience of life as valuable and meaningful. The wellbeing of patients is paramount and requires a range of interventions, such as a highly personal approach, a flexible dealing with rules, a great dose of creativity in everyday life, extensive expertise in somatic care, and specific attention to existential needs and the search for meaning. The development of this care model in a number of care units in Flanders increases the wellbeing of the patients and creates a significant positive dynamic among caregivers. However, more research and resources are needed to further develop and integrate this model.

Persons with severe and persistent mental illness (SPMI) make up a vulnerable group within mental healthcare and society. Not only do they suffer from long-term, serious psychiatric disorders; they often also experience considerable problems in their psychosocial functioning. Research has disclosed that the care needs of this target group are complex, and that the life expectancy of these persons is significantly lower than in the general population. Given (1) the lower life expectancy of persons with SPMI, (2) the higher suicide risk related to mental disorders, and (3) the legalization and practice of medical assistance in dying in an increasing number of countries, it is of utmost importance to map the ethical aspects and challenges of end-of-life care needs in persons with SPMI. Therefore, we charted the way end-of-life care is provided for them by means of a scoping review of the scientific literature, with an emphasis on the ethical aspects surrounding it. We explore existing ethical dilemmas; the underlying ethical values, principles and attitudes; and the locus and stakeholders of ethical dialog regarding end-of-life care in persons with SPMI. The results indicate that the four guiding principles of biomedical ethics can well be identified in the literature, and are each addressed in their own specific way: Autonomy in relation to questions regarding the decision-making capacity of persons with SPMI; Justice in relation to access to quality care and the presence of stigma; and Non-maleficence and Beneficence in relation to the ongoing debate regarding the benefits and obstacles in applying palliative care approaches in the context of psychiatry, and the status of the futility-concept therein. Personal virtues and attitudes in care professionals, like compassion, non-abandonment and upholding dignity are key, as care professionals are the main advocates of persons with SPMI, which often lack an extensive social network. Further, we find that the ethical dialog is mainly focused on care professionals and relatives, rather than the persons with SPMI themselves. This is reflected in the existing research that often had the voices of the latter missing. Future research may benefit from the inclusion of persons with SMPI’s first-hand accounts. End-of-life care for persons with SPMI may benefit from identifying and integrating (locally developed) good practices like cross-sectoral education, specific care models, and ethics support.

Dealing with refusal of care by patients with a severe psychiatric disorder in combination with a life-threatening condition: a case report Providing good care for persons with a severe psychiatric disorder in combination with a life-threatening condition is a major challenge for health care providers. By means of a case report, the authors analyze the situation of a 65-year-old woman with Korsakov’s disease, depressive symptoms and aplastic anemia. She refuses to be examined and treated, despite many efforts on the part of the caregivers and relatives, as well as the seriousness of the situation. The team has to switch from a curative to a palliative approach in a short space of time. Various areas of tension are assessed: appraising the decision-making capacity of the person requesting care, dealing with refusal of care in a life-threatening situation, and involving and coordinating the various parties concerned, including the psychiatric and somatic care providers, administrator and family. The case uniquely illustrates the challenges described in international literature and recent local studies. The authors plead for the importance of the liaison function between psychiatric and somatic care and the central role of the general practitioner associated with the psychiatric facility. The careful clarification of the legal capacity of the patient who refuses life-saving care, the added value of ethical consultation in order to come to a supported approach and to channel moral distress, and the involvement of a palliative support team within a psychiatric setting are also crucial elements in the approach.
