Claim 14:
15. A medical information management apparatus, comprising processing circuitry configured to:
search medical information stored in a 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;
classify the items included in the condition-matched medical information into an item which is essential and an item which is not essential in terms of a purpose of utilization, and delete the item which is not essential and a value corresponding to the item which is not essential from the condition-matched medical information to generate essential medical information;
perform a process of specifying entry items which correspond to idiosyncratic information from a 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 essential 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;

generate and display a rounding setting screen on a terminal of the user if the idiosyncratic information corresponds to an 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; 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.
