A group of researchers led by Maria Pikoula from theÌýInstitute of Health Informatics, ¹û¶³Ó°ÔºÌýand Jennifer Kathleen Quint from Imperial College London, have recently had their research on the topic of Chronic Obstructive Pulmonary Disease (COPD) subtypes published in BMC Medical Informatics and Decision Making.

The group sought to discover, describe and validate COPD subtypes using cluster analysis on data derived from electronic health records. They applied two unsupervised learning algorithms in 30,961 current and former smokers diagnosed with COPD. This enabled them to identify and characterize five COPD patient clusters with distinct patient characteristics. The subgroups have differing risk factors, comorbidities and prognosis.

These findings are in line with previous related studies and draw attention to anxiety and depression as important drivers of COPD in young, female patients.
