A medical study support apparatus manages study data, and displays a study list on a monitor screen. In the study list, data items on each study, including patient's personal information such as its name, birth date, sex and address as well as study items such as study ID, study date, study type and progress of study, are displayed in a lined for one case after another. The medical study support apparatus cooperates with an electronic chart apparatus. As chart data of a particular patient is displayed on its monitor, the electronic chart apparatus sends a trigger signal to the medical study support apparatus along with ID data of the particular patient. Upon receipt of the trigger signal and the ID data, the medical study support apparatus conceals the personal information on other patients than the particular patient in the study list.
