Emergency Department Admissions: Analysis of CDS Dataset (part 10)
I analyse an anonymised data dump of 1.9 million admissions records to the emergency departments of an undisclosed NHS Trust for the period June 2017 – September 2021

Five weekly periods have been identified when the ratio of in-hospital to emergency department death was substantially and remarkably elevated, these occurring during lockdown (2020/w15 - w16 covering the period 3 April - 17 April 2020) and immediately after vaccine rollout (2021/w2 - w4 covering the period 9 January – 29 January).
The anonymised electronic patient records for a sample of 21,928 adult in-hospital deaths occurring between 1 January 2020 and 10 September 2021 for an undisclosed NHS Trust were subject to statistical analysis in order to identify correlates for the peculiar periods.
A neural network model (multilayer perceptron) was developed revealing the relative importance of 42 clinical variables, enabling a patient profile to be formulated for these two unique periods. Total diagnoses made, age at death, COVID-19 diagnosis and diabetes featured as the top four discriminators.
