DIP uses big data to analyze and guide the behavior of different regions, different periods, and different medical institutions, focusing on the unit of disease combinations, and according to the functional positioning of medical institutions at all levels, through the difference in the size of the scores assigned to different types of diseases, reflecting the guiding role of the treatment mode.
