    How should we manage fatigue in on-call workers? A review of guidance materials and a systematic review of the evidence-base
    (Elsevier Ltd, 2025-02) Bumpstead H; Kovac K; Ferguson SA; Vincent GE; Bachmann A; Signal L; Aisbett B; Thomas MJW; Sprajcer M; Vitiello M
    On-call work is known to contribute to disrupted sleep, fatigue, and an increased risk of incidentor injury. This review aimed to a) identify current on-call management strategies that are suggested or required by regulatory bodies, and b) determine if there is empirical evidence to support these strategies in managing the fatigue of on-call workers. A grey literature search produced 65 relevant guidance materials. A systematic inductive thematic process identified consistent strategies included in these materials: 1) regularity/predictability of shifts, 2) fatigue management policy, 3) prescriptive rule sets, 4) fitness for work assessment, 5) on-the-day control measures, 6) risk assessment, 7) training and education, and 8) call management. Subsequently, a systematic review identified 17 original studies on the effectiveness of fatigue management strategies in on-call workers. Very little research has been done on fatigue management strategies for on-call workers outside of some prescriptive hours of work limitations. These limitations generally reduced fatigue, but often had the unintended consequence of increasing workload, which may inadvertently increase overall risk. Training, education, and call management (e.g., protected naps during on-call periods) also had some supporting evidence. The current gap in evidence emphasises the critical need for research on tailored on-call fatigue management strategies.

    "It's Just [Complicated] Sleep": Discourses of Sleep and Aging in the Media.
    (Oxford University Press, 2023-12) Breheny M; Ross I; Ladyman C; Signal L; Dew K; Gibson R
    The media are influential in shaping beliefs and attitudes on aging and health-related behaviors. Sleep is increasingly recognized as a key pillar for healthy aging. However, the role of media representations of sleep is yet to be assessed with regard to discourses of aging. Texts from New Zealand's main free online news source were collated using key words "sleep" together with "aging," "older," "elderly," or "dementia" between 2018 and 2021. Contents of 38 articles were interpreted using critical discourse analysis. Discursive constructions described an inevitable decline of sleep with aging, including impacts of both physiological decline and life stage transitions; sleep's role as both a remedy and risk for ill health and disease; and the simplification of solutions for self-managing sleep juxtaposed alongside recognition of its complexity. The audience of these complex messages is left in the invidious position of both pursuing sleep practices to prevent age-related decline, whilst also being told that sleep degradation is inevitable. This research demonstrates the complexity of media messaging and the fraught options it offers: good sleep as both a reasonable achievement to strive for and as impossibly idealistic. Findings mirror two predominant health identities available to older people, as responsible for resisting aging or as falling into inevitable decline. This reveals additional expectations around appropriate time use and behaviors with aging. More nuanced messaging that goes beyond sleep as a resource for health and waking productivity is recommended. Acknowledging the complexity of sleep, aging, and society could be the starting point of such adaptation.

    Sleep as a social and cultural practice in Aotearoa: a scoping review
    (Taylor and Francis Group, 2024-09-22) Ross I; Signal L; Tassell-Matamua N; Meadows R; Gibson R
    Traditionally, sleep science is grounded in biology, physiology, and medicine. But socio-cultural considerations provide a crucial lens into sleep health. Exploring the sociology of sleep in Aotearoa New Zealand (AoNZ) could broaden our understandings and better represent sleep-related practices among our diverse communities. This scoping review represents the pre-existing literature concerning sleep as a social or cultural practice in AoNZ. The initial search (via Discover and Scopus) search yielded 2,442 results. Of these results, 113 manuscripts were characterised of interest, but only 20 were directly related and included in the review. This literature was presented in relation to Meadows’ (2005) modes of ‘sleep embodiment’ including sleep practice norms, the pragmatics of sleep and social roles, individual experiences and feelings related to sleep, and the visceral need for sleep. The findings highlight the progress of sleep literature in AoNZ. This covers diverse sleep practices, perspectives and experiences of sleep and sleeping, as well as the broader socio-cultural factors and unique AoNZ context that influence sleep. However, gaps in the field of local sleep research are also identified. Findings lay the foundation for further research in AoNZ to explore sleep-related discourses and practices that will ultimately broaden existing perspectives.
