This study aims to understand the effects that role-diverse online communities have on informal carers, particularly in providing support. Australian Facebook communities used to support those involved in the National Disability Insurance Scheme (NDIS) were explored. Social network analysis of an NDIS-centred community was conducted, based on 909 publicly visible interactions that occurred in May-June and August-September 2019. Two managers of informal NDIS communities were interviewed, the transcripts of which were analysed using NVivo. Results from the two analyses suggest that both an individual carer\'s attributes and the collective attributes of the network defined the capability of the network to support the carer, often depending on the experiences and expertise of those offering support. Support was unconstrained by role, though differing goals and expectations often impeded collaboration between roles. The outcomes of support provision were shown to affect not only individuals but also the collective network. However, while effective, community spaces currently lack organisational backing and resources available to informal communities are constrained. Findings drawn from this study, which we believe are applicable to a broader, international context, are three-fold. Firstly, it is recommended that informal support communities clearly define purpose and create multiple channels to ensure that all participants can meet their needs. Secondly, the benefits of participation to organisations should be further explored. Finally, the use of social network analysis as a method in this study has provided significant insights into the communication patterns and activities of the community under study. Future use of SNA in similar studies may provide further insight into the effectiveness and interactions of community-based support methods.

Carers of people with dementia can experience reduced health and well-being, but little is known about how best to support them. There is some evidence to suggest that case management may improve outcomes for carers but less evidence about the features of case management services that can effectively support carers of people with dementia. Admiral Nursing operates a case management approach staffed by specialist nurses and is the only service of its kind in the United Kingdom dedicated to helping people with dementia and their carers. This paper reports qualitative findings from a mixed methods study of Admiral Nursing. For the qualitative strand of the project, data were collected in focus groups and in-depth interviews with carers of people with dementia (n = 35) and analysed thematically using the framework approach. The aim of this analysis was to understand differences between the experiences of the carers in our sample with and without Admiral Nursing, applying Freeman\'s model of continuity of care (Freeman et al., Continuity of care, 2000). Participants who had received Admiral Nursing were recruited from two geographical locations and carers without experience of this service were recruited from two different areas. We found that carers in our sample felt \'supported\' in circumstances where they received an ongoing service from an Admiral Nurse or other professional with expertise in dementia who was able to develop a meaningful relationship with them over time. We conclude that ongoing support, expertise in dementia and a meaningful relationship are key features of relationship continuity common in carers\' reports of feeling supported. Specialist nurses are well placed to provide this continuity.

Many people with dementia are cared for by family members. Family carers often feel bound to support the person with dementia at the expense of their own needs, which can be neglected. They often experience distress when making decisions, especially over ethical dilemmas when their own interests and those of the person being cared for conflict. This paper presents a case study approach to consider best interests decision making for families affected by dementia. In the case study, a carer is supporting his father to remain living at home although he feels this unsafe and the demands of this cause tension with his family and affect his performance at work.
