Abstract: According to one embodiment, a medical information processing apparatus includes processing circuitry. The processing circuitry acquires first and second medical images acquired in at least first and second time phases. The processing circuitry inputs the first and second medical images into a gene mutation classification model to generate first and second gene mutation classification results. The processing circuitry judges consistency of the gene mutation classification model based on the first and second gene mutation classification results.

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 learning assistance apparatus according to an embodiment includes processing circuitry. Based on a knowledge base in which a condition of medical data as an index for medical judgment and medical knowledge derived from the condition are associated with each other, and a model designed to derive a medical inference result from a condition of medical data concerning a subject in response to input of the medical data, the processing circuitry compares the medical data condition related to the derivation of the medical knowledge and the medical data condition related to the derivation of the inference result, for each item of the medical data, and outputs a result of the comparison.

Abstract: A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a first diagnostic result by a clinical decision support system before learning of first data, a second diagnostic result by the clinical decision support system after learning of the first data, a diagnostic result by a doctor, and the first data. The processing circuitry extracts an example that is subjected to an influence of updating of the clinical decision support system by a prescribed criterion or more as an example to be presented. The processing circuitry outputs the example to be presented in association with a diagnosis influence degree indicator indicating a degree of an influence that the clinical decision support system exerts on diagnosis by the doctor.

Abstract: A consensus building support system according to an embodiment includes processing circuitry. The processing circuitry stores a database that stores a state of a first user and actions by the first user and a second user. The processing circuitry calculates a first state assessment index representing a first user's assessment of the state based on a first user's state and an action relating to the first user, and calculates a second state assessment index representing a second user's assessment of the state based on the first user's state and an action relating to the second user. The processing circuitry display a first state assessment index and/or a second state assessment index on a display.

Abstract: A medical information processing apparatus according to an embodiment includes a processing circuitry. The processing circuitry acquires operation information of a medical worker for medical treatment information of a target patient or operation information of a medical worker for medical treatment information of a similar patient who is similar to the target patient. Based on the operation information, the processing circuitry calculates the concordance rate between a period for which the medical treatment information of the target patient or the medical treatment information of the similar patient is referred to and the period for which the medical treatment information of the target patient is displayed. The processing circuitry performs display of information about the concordance rate.
