Fuente: Wipo "BigData" The invention provides a medical big data information acquisition method and system, belonging to the technical field of medical big data. The method comprises the steps of acquiring at least two pieces of medical service tracking data corresponding to each piece of medical object attribute information of a to-be-processed medical object, and performing fusion processing on the at least two piecesof medical service tracking data corresponding to each piece of medical object attribute information to obtain at least two medical data tracking sets; generating an object data attribute identifiercorresponding to each piece of medical object attribute information according to tracking set verification codes of the medical data tracking sets to which the at least two pieces of medical service tracking data in each piece of medical object attribute information belong; and finally, according to the object data attribute identifiers, acquiring target medical object attribute information needing to be stored in the to-be-processed medical object, and locally storing the target medical object attribute information. With the medical big data information acquisition method and system, the effective utilization rate of storage space can be improved.
