Time-ordered comorbidity correlations identify patients at risk of mis- and overdiagnosis

Abstract: Diagnostic errors are common and can lead to harmful treatments. We present a data-driven, generic approach for identifying patients at risk of being mis- or overdiagnosed, here exemplified by chronic obstructive pulmonary disease (COPD). It has been estimated that 5–60% of all COPD cases are misdiagnosed. High-throughput methods are therefore needed in this domain. We have used a national patient registry, which contains hospital diagnoses for 6.9 million patients across the entire Danish population for 21 ye… Show more

“…In this context, a number of statistical and machine learning methods are being developed for discovering temporal disease trajectories in large-scale databases with electronically registered patient histories [1][2][3][4][5][6][7][8][9]. Specifically, these approaches investigate patient histories that consist of medical diagnoses in the form of International Classification of Diseases 9 or 10 (ICD-9 or ICD-10) codes [10] or other standardized medical description codes (SNOMED, READ, MedDRA) recorded for each doctor visit.…”

“…The term "disease trajectory" then refers to a series of diagnoses in such a standardized format. The databases targeted by these analyses typically contain thousands of patients and span several years [1][2][3][4][5][6][7][8][9].…”

“…Population-wide disease trajectory analysis was first proposed by Jensen et al, 10 and has since been applied and tested in several large-scale cohort studies [11][12][13][14][15] to explore temporal patterns of progression in diseases of diverse categories, such as cancer, 16,17 diabetes mellitus, 18 and depression, 19 discover potential differences in possible shared etiologies or disease mechanisms through disease clustering and help generalize key pathways for disease onset in the future. Moreover, a study conducted a disease trajectory analysis among women and used biomarkers representing preclinical states to identify potential indicators of disease at an earlier stage.…”
