Abstract: A medical diagnosis support device of an embodiment includes processing circuitry. The processing circuitry acquires first reference data based on first clinical data relating to a diagnosis result of an evaluation target and second reference data based on second clinical data relating to a comparison target diagnosis result for the evaluation target and performs an analysis process relating to the diagnosis result of the evaluation target based on the first reference data and the second reference data. The first reference data includes first data that has been referred to by a first user to obtain the diagnosis result of the evaluation target and second data that has been referred to by a diagnosis support system to obtain the diagnosis result of the evaluation target. The second reference data includes the first data that has been referred to by at least one of the first user and a second user different from the first user in order to obtain the diagnosis result of the comparison target.

Abstract: A diagnosis and treatment support system according to an embodiment has a storage apparatus and processing circuitry. The storage apparatus stores a trained model that infers information related to a state of a patient from an examination value for a predetermined examination item. On the basis of correlations between examination values for plural examination items included in diagnosis and treatment information on plural patients, the processing circuitry calculates a conversion function that enables statistical derivation of a value from an examination value or values for one or plural examination items, and generates, on the basis of an inference obtained by inputting an examination value for an examination item included in diagnosis and treatment information on a target patient into the trained model, support information for supporting diagnosis and treatment of the target patient. Furthermore, the processing circuitry derives, on the basis of the conversion function, an examination value for a lacking examination item from an examination value for an examination item included in the diagnosis and treatment information on the target patient and causes the trained model to infer information related to a state of the target patient, in a case where examination items included in the diagnosis and treatment information on the target patient do not satisfy a requirement for the predetermined examination item.

Abstract: A clinical decision support device of an embodiment includes processing circuitry. The processing circuitry acquires at least one of attribute information of a patient and first parameters regarding a first preference category for the patient. The processing circuitry estimates second parameters of the patient with respect to a second preference category on the basis of at least one of the attribute information and the first preference category. The processing circuitry determines preferable selections of the patient with respect to a predetermined preference category on the basis of the second parameters. The processing circuitry displays the preferable selections and the second parameters in association with each other.

Abstract: A medical information processing apparatus of an embodiment includes processing circuitry. The processing circuitry acquires biometric data regarding a subject. The processing circuitry identifies reference data regarding a first feature amount on the basis of the biometric data. The processing circuitry acquires a second feature amount by inputting the first feature amount included in the biometric data into a model capable of mutually converting the first feature amount and the second feature amount. The processing circuitry derives pseudo-feature data regarding the first feature amount simulated by inputting the second feature amount into the model. The processing circuitry determines reliability scores with respect to the biometric data on the basis of the reference data and the pseudo-feature data.
