METHOD AND SYSTEM FOR SUPPORTING A CLINICAL DIAGNOSIS
First Claim
1. An automated method for supporting a clinical diagnosis, comprising:
- storing a plurality of symptoms associated with a patient, the symptoms including characteristics of the patient, wherein each symptom is categorized as a present symptom, an absent symptom, or an open symptom;
a processor establishing a multi-tier relationship between said plurality of symptoms and a plurality of diseases;
the processor adjusting at least one weighting factor for at least one (a) at least one of said multi-tier relationships and (b) at least one of said symptoms, based on a knowledge model; and
the processor building a ranking of diseases from said multi-tier relationship based on said weighting factors.

Abstract
Methods and systems may support conclusions of a clinician by enabling the clinician to arbitrarily define the symptoms according to the patient'"'"'s record. The method may comprise: (a) determining a plurality of symptoms representing a patient and including characteristics of the patient, the symptoms being categorized as present symptoms, absent symptoms or open symptoms; (b) establishing a multi-tier relationship between said symptoms and a plurality of diseases based on a knowledge model; (c) adjusting weighting factor(s) for at least one multi-tier relationship based on said knowledge model; (d) optionally adjusting at least one weighting factor of step (c) by an expert; and (e) building a ranking of diseases from said multi-tier relationship based on said weighting factors. The method may provide an efficient ranking of disease information, thereby supporting a clinical diagnosis that may consider multiple symptoms while emphasizing particular symptoms in view of the clinician'"'"'s expertise.

4. A system for supporting a clinical diagnosis, the system comprising:
-
a semantic patient record module storing semantically annotated symptoms associated with a patient, the symptoms including characteristics of the patient, wherein each symptom is categorized as a present symptom, an absent symptom, or an open symptom; a weighted disease-symptom module including a knowledge model configured to establish a multi-tier relationship between said plurality of symptoms and a plurality of diseases; the weighted disease-symptom module configured for adjusting at least one weighting factor for at least one (a) at least one of said multi-tier relationships and (b) at least one of said symptoms, based on a medical ontology module; the weighted disease-symptom module configured for building a ranking of diseases from said multi-tier relationship weighted by said weighting factors; wherein the weighted disease-symptom module is embodied by software stored in a non-transitory computer-readable medium and executable by a processor.
