Abstract

Method and apparatus for processing medical data. The method for processing indication conditions includes obtaining a plurality of predetermined indication conditions which relate to a plurality of parameters and forming a plurality of conditional segments based on respective values of the plurality of parameters, which respectively correspond to a plurality of combinations of value ranges of the plurality of parameters. The method for processing patient data includes obtaining distribution information of the patient data in the plurality of conditional segments formed above and determining a matching relationship of patient data with at least one indication condition. The apparatuses correspond to the methods. Based on this, a matching relation of patient data with the plurality of indication conditions is determined directly based on distribution of patient data in respective conditional segments, which reduces/avoids chances of inefficiency caused by multiple data acquisitions, conversions, and analysis and improves processing efficiency of patient data.
