    Can a systems approach reduce adverse outcomes in patients with dementia in acute settings? (innovative practice)
    (SAGE, 2017-11-03) Duah-Owusu White, Mary; Vassallo, Michael; Kelly, Fiona; Nyman, Samuel
    People with dementia experience adverse outcomes such as pressure sores during their stay in acute hospitals. The application of a systems approach in an acute setting places an emphasis on the patient's journey in addition to the organisational factors that are present within a hospital context. This article draws upon principles obtained from a theoretical model, which was extracted from the work of Edwards (1972), Hawkins (1987) and Zecevic et al. (2007), in order to illustrate how the application of a novel systems approach (human interaction, environment, equipment and policy) could be used in acute hospital settings to reduce adverse health outcomes by using an imaginary patient with dementia.

    Two factors that can increase the length of hospital stay of patients with dementia
    (Elsevier, 2022-12-02) Duah-Owusu White, Mary; Vassallo, Michael; Kelly, Fiona; Nyman, Samuel
    Objectives Patients with dementia are at greater risk of a long hospital stay and this is associated with adverse outcomes. The aim of this service evaluation was to identify variables most predictive of increased length of hospital stay amongst patients with dementia. Methods/Design We conducted a retrospective analysis on a cross-sectional hospital dataset for the period January–December 2016. Excluding length of stay less than 24h and readmissions, the sample comprised of 1133 patients who had a dementia diagnosis on record. Results The highest incidence rate ratio for length of stay in the dementia sample was: (a) discharge to a care home (IRR: 2.443, 95% CI 1.778–3.357), (b) falls without harm (IRR: 2.486, 95% CI 2.029–3.045). Conclusions Based on this dataset, we conclude that improvements made to falls prevention strategies in hospitals and discharge planning procedures can help to reduce the length of stay for patients with dementia.
