Zusammenfassung: | We introduce a simulated digital model that learns a person's baseline blood
health over time. Using an adaptive learning algorithm, the model provides a
risk assessment score that compares an individual's chronological age with an
estimation of biological age based on common immune-relevant markers used in
current clinical practice. We demonstrate its efficacy on real and synthetic
data from medically relevant cases, extreme cases, and empirical blood cell
count data from 100K data records in the Centers for Disease Control and
Prevention's National Health and Nutrition Examination Survey (CDC NHANES) that
spans 13 years. We find that the score is informative in distinguishing healthy
individuals from those with diseases, both self-reported and as manifested via
abnormal blood test results, providing an entry-level score for patient
triaging. The risk assessment score is not a machine learning black-box
approach but can interact with ML and DL approaches to help guide, control the
attention given to specific features, and assign proper explainable weight to
an otherwise transparent adaptive learning algorithm. This approach may allow
fast and scalable deployment to personalised, sensitive, and predictive
derivative indexes within digital medicine, without the need for a new test,
assay, or prospective sampling, unlike other biological ageing-related scores
and methods. It demonstrates the potential of clinical informatics and deep
medicine in digital healthcare as drivers of innovation in preventive patient
care. |
