Identity matching between historical patients and newly admitted patients is the primary problem in the field of med-ical electronic medical record content sharing.Aiming at the shortcomings of existing algorithms such as simple process and lack of optimization,a W-EMPI algorithm based on PIX technology and RIM model is proposed.Firstly,the standard data set is obtained by data cleaning.Then the unique feature information is used to filter out the real-name data.Finally,patient identity matching is carried out through similarity evaluation to achieve the combined positioning of similar patients.The algorithm has been preliminari-ly applied in the EMPI system of a large tertiary hospital in Jiangsu Province.The practical effect show that compared with the tradi-tional procedure,the proposed algorithm has higher accuracy and can more effectively complete patient matching.
