COVID-19 Infection and Machine Learning Using Artificial Intelligence (AI)

This is an observational study which will be carried out at East Suffolk and North Essex NHS Foundation Trust (ESNEFT) in collaboration with University of Suffolk (UoS). Investigators aim to analyse subsets of lymphocytes in the prospective blood smear slides using machine learning and AI algorithm obtained from participants with a positive qPCR test for COVID-19 who have required a hospital admission. The control group will consist of archived blood smear slide data from patients both with i) non-suspected viral infections, and ii) those with a non-COVID-19 viral infection obtained prior to the emergence of COVID-19 infection in the United Kingdom. In total, 785 blood smear slides will be analysed. The aim of this study is to establish the diagnosis of COVID 19 infection based on lymphocyte morphology on patients with COVID-19 infection from other patients with non COVID -19 viral infections. A high definition single cell lymphocyte image from patients with COVID 19 infection and control group will be analysed using open source histopathology imaging software CellProfiler against very fine cytoplasmic and nuclear details of the cells through supervised and unsupervised machine learning algorithm to identify recurring pattern that is unique to COVID 19 infection. The study will also assess other relevant clinical, haematological and biochemical parameters in conjunction with the above morphological features to develop a risk stratification tool to predict the clinical outcome of patients with COVID-19 infection with high specificity and sensitivity using bioinformatics pipeline.
