Classification: CPC G  H | IPC G  H

Claim 8:
9. A medical information management system, comprising:
a storage which stores medical information including a key being an item of information regarding a patient and a value being contents of the key; and
processing circuitry configured to:
search the medical information stored in the storage, when accepting a search request of the medical information from a user, and extract the medical information which matches a search condition as condition-matched medical information, wherein the medical information includes items of patient information and contents of the items;
perform a process of specifying a plurality of entry items which correspond to idiosyncratic information from the plurality of entry items from which exclude a patient name and a patient identification, wherein the process includes:
extracting the items and the contents from the condition-matched medical information and perform first anonymization processing on the extracted items and contents;
calculating a proportion of an amount of medical information in which the items are included compared to an entire amount of medical information stored in the storage; and
determining that one of the contents is idiosyncratic information when the proportion is equal to or less than a threshold, wherein the threshold is set with respect to each of the items, and there is a high possibility to specify a specific patient if the one of the contents is the idiosyncratic information to generate a first determination result;
determine whether or not the key of the value determined to include the idiosyncratic information corresponds to an essential key being a key which is essential in terms of a purpose of utilization to generate a second determination result;
output the condition-matched medical information, the first determination result, and the second determination result;
generate and display a rounding setting screen on a terminal of the user if the idiosyncratic information corresponds to the essential key in terms of the purpose of the utilization, wherein the rounding setting screen causes the user to set the search condition to be a broader concept such that a number of target patients is increased; and
receive a confirmation result from the user, and perform second anonymization processing on the condition-matched medical information on which the first anonymization processing was performed when the confirmation result requests processing to perform anonymization.
