- the reference information storage unit 185 stores the reference history displayed in the workflow step reference history area 903 in the medical information database 105 as reference information in association with the workflow step being executed.
- the workflow step information referred to based on the reference information is extracted, but the information identified by the reference information may be other than the workflow step information.
- the information identified by the reference information may be other than the workflow step information.
- an external medical encyclopedia or standard practice guidelines may be used.
- step S1507 the similarity calculation unit 181 displays the conference flag of the workflow step associated with the medical information Ui that is the similarity calculation target, in addition to the sum of the similarities Sj calculated using each evidence output data.
- a conference at a medical site is usually a conference held by medical personnel including multiple doctors, and the medical information generated at the conference means medical information that has been approved by multiple medical workers. To do. Therefore, it can be said that medical information whose conference flag is “true” is more reliable medical information. Therefore, in order to weight the similarity Sj by the conference flag, a constant Cf of 1 or more is set in advance, and when the conference flag is “true”, the similarity is weighted by multiplying Sj by Cf. Alternatively, an input screen for the operator to set Cf may be provided separately.
