Solution Overview
Problem
Medical professionals face challenges in comprehensively viewing and analyzing time-series data for diagnosis and treatment processes, including drug administration, medical tests, and vital signs, which hinders effective decision-making and treatment assessment.
Innovation Solution
A medical information processing apparatus with a display controlling unit, tallying unit, and calculating unit that displays events in a time series, tallies numerical values for each section of the display period, and calculates context information by comparing these values to associate with diagnosis and treatment actions, facilitating a bird's-eye view of patient data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If various types of diagnosis and treatment data are displayed in a time series on a single screen, then medical professionals can view data comprehensively, but the complexity of the display system increases
Solution Approach 1:
The patent divides the display period into multiple tally units (time segments) and displays data for each segment separately. This segmentation allows comprehensive data presentation while maintaining organizational structure, reducing the perceived complexity through systematic division of the time axis into manageable units.
Solution Approach 2:
The patent introduces a temporal dimension by displaying data in a time series format across multiple tally units. This dimensional approach organizes complex data along the time axis, allowing comprehensive viewing while structuring information in a way that reduces cognitive complexity through temporal progression.
2Loss of information
If context information is calculated by comparing index values across tally units, then understanding of diagnosis and treatment actions is improved, but the calculation and processing complexity increases
Solution Approach 1:
The patent performs preliminary tallying of numerical values for each tally unit before conducting comparisons. This preliminary organization of data into standardized tally units simplifies subsequent context calculation by pre-processing and structuring the data, reducing the complexity of the comparison operation.
Solution Approach 2:
The patent introduces index values as an intermediary representation between raw data and context information. These index values serve as simplified mediators that capture essential characteristics of each tally unit, making comparisons more manageable and reducing processing complexity while preserving meaningful information.
3Measurement precision
If numerical values are tallied for each tally unit to show changes over time, then analysis capability is improved, but the data processing time increases
Solution Approach 1:
The patent segments the display period into multiple tally units and performs tallying independently for each segment. This segmentation enables parallel processing potential and organized data structure, improving analysis precision through detailed temporal breakdown while managing processing time through systematic division of the calculation task.

AI summary
A medical information processing apparatus according to an embodiment includes: a display controlling unit configured to display, in a time series, events of diagnosis and treatment actions performed on a subject during a designated display period; a tallying unit configured to tally, as an index value, numerical values either extracted or calculated on the basis of information about the events, for each of tally units obtained by dividing the display period into sections arranged in a time series; and a calculating unit configured to calculate a piece of context information relatively indicating one selected from between the diagnosis and treatment actions and a state of the subject in each of the tally units, by comparing the index values tallied for the tally units with one another, and to further display the pieces of context information so as to be kept in association with the events.
