  • Research summary

    This is a part time PhD project to automate clinical coding. Clinical Coding is the process of assigning structured medical codes to a patient’s notes to categorise the procedure/care they received, any diagnosis that was given and any comorbidities the patient had at the time of their hospital episode. This is currently done manually within the NHS by a team of trained clinical coders. However there is a shortage of qualified clinical coders in the UK and the backlogs of cases requiring coding are growing. The research project’s aim is to train machine learning or artificial intelligence models using existing NHS data to automate the classification of OPCS4 procedure codes and ICD10 primary diagnosis and comorbidity codes using patient’s hospital notes. These outputs will then be reviewed by the clinical coding teams to aid reducing the backlogs.
