Peer support is well established in fields such as the disability movement and mental health and is increasingly recognised as one way of enabling support by and for people with a diagnosis of dementia and their immediate carers. It was central to the implementation of the National Dementia Strategy (NDS) for England, when 40 demonstration sites were established. This mixed-methods study included in-depth qualitative interviews with people living with dementia (n = 101) and staff/stakeholders (n = 82) at 8 of the 40 sites. Data analysis was a five-stage process: coding framework developed (using 25 transcripts); further development of the framework (using a further 70 transcripts); development of emerging themes; modelling of themes and verification of models based on the entire data set. Peer support had positive emotional and social impact that was rooted in identification with others, a commonality of experience and reciprocity of support. There was also a contrast between the quality of peer support and support from professionals. This emphasises the significance of lived experience and promoting a strength-based approach to interpersonal support that is enabling and challenges a deficit approach to understanding dementia.

The active management of the experience of living with dementia appears to improve quality of life despite the lack of disease modification. However, research to date has been largely of modest scale and explanatory factors for improvements have been under-conceptualised. Thus, although promulgated through national strategies, the evidence base is relatively weak. This paper reports on a nation-wide study of the influence of the National Dementia Strategy for England in relation to Dementia Adviser and Peer Support Network services in 40 demonstration sites. The research aimed to identify ways in which the services contribute to the wellbeing and resilience of people with dementia and care partners. A mixed-methods research design collected data through: activity and outcome monitoring; organisational surveys; in-depth case studies, including qualitative interviews with people with dementia (N = 47) and care partners (N = 54), wellbeing and quality of life measures, and interviews with staff and other stakeholders (N = 82). Three themes are explored: addressing individual and community needs; promoting independence, control and choice; and getting a life back. Services promoted independence, control and choice, and consequently enabled people to re-narrate their lives as purposeful within their communities. Ways in which these are achieved resemble the public health model of lay health advisor and this research adds to the imperative to approach dementia as a key public health concern.

SummaryHypoxaemia during anaesthetic induction in obstetrics is hazardous for mother and baby, but the onset of desaturation can be delayed by pre-oxygenation. This study investigated pre-oxygenation during pregnancy using computer simulation. The Nottingham Physiology Simulator was configured to replicate normal pregnant physiology. Three pregnant and three non-pregnant subjects were created, representing population variation according to published physiological values. They underwent pre-oxygenation by tidal and vital capacity breathing of 100% oxygen. Pre-oxygenation during tidal breathing proceeded more rapidly in pregnancy, the median [range] time to achieve 95% of the maximum change in P É O 2 being 1 min 37 s [1:23-1:52] in pregnant subjects, compared to 2 min 51 s [2:28-3:15] in non-pregnant subjects. Vital capacity pre-oxygenation required seven breaths [5][6][7][8][9][10] in pregnant subjects, compared to six breaths [4][5][6][7][8][9] in non-pregnant subjects, to achieve the same P É O 2 as after 95% complete tidal pre-oxygenation. We recommend 2 min of tidal breathing for pre-oxygenation in pregnancy.
