"Faced with pages of notes describing several episodes of an illness, how do doctors find small details such as blood test results in the text? They use their medical knowledge to identify likely blood test ‘numbers’ e.g. 12mg/L, and contextual clues such as clusters of associated words like ‘blood’, ‘test’, ‘CRP’, and ‘cholesterol’. Because psychiatric records are so long and unstructured, medical research studies have rarely looked at more than a few hundred i.e. numbers that a small team of human researchers can read."
"By pre-reading large numbers of example records, Evolution AI’s system has been trained, like a doctor, to rapidly recognise the ‘language of blood tests’ in the 200, 000 anonymised records that will be used in this research study. An example of a record entry might be: ‘Xxxx presents with a history of a manic mood type. His associated symptoms include irritable mood. He reports the duration has been for improving for last 2 weeks. Blood tests showed Cholesterol, Total 210 mg/dl, CRP of 12mg/L and HbA1c level 6.0%’. Having extracted the data using Evolution AI products, the research team will map how inflammatory markers, such as CRP, change at times of relapse and recovery, over the eight years the psychiatric records cover."
