Statistician, University of Dundee
Grade 7 SP 29-33, £31,604-£35,550
Duration of employment: 21 months, Closing Date: 8 April 2018
This post is part of an innovative project to examine a series of 3300 CT scans in NHS Fife on older people aged 65 and over admitted as an emergency to hospital. The primary hypotheses are that (a) brain atrophy, and (b) white matter hyper-intensities (WMHs) are associated with higher delirium risk. The secondary hypotheses are that in patients with delirium, greater degrees of (a) brain atrophy, and (b) WMHs, predict worse outcomes such as mortality, readmission and new institutionalisation. For each of the hypotheses, appropriate variables such as age, pre-admission dementia status, physical comorbidity and activities of daily living will be controlled for.
The role of the statistician will be to analyse this cohort linked to routine datasets such as SMR01 and GRO. For outcomes that are binary over a fixed period of time such as 30 day mortality logistic regression modelling will be used to assess associations with CT factors described earlier along with binary markers for delirium, cognitive impairment, dementia, demographic factors and co-morbidity. Co-linearity will be assessed as there may be variables that are precursors or markers of each other in the model simultaneously.
