Abstract:: Abstract: A similarity matching algorithm is proposed to construct a MIMIC-III waveform database matched subset for solving the problem of low matching degree between MIMIC-III clinical database and waveform database. After filling in the missing ICU location information using BP neural network, the matching algorithm is used to calculate the similarity of non-invasive blood pressure between the two databases, and the matching records with high similarity are examined and selected to construct a new matched subset. A total of 1 133 waveform database records are matched. The matching results show that the proposed method has high accuracy and efficiency, with an average matching accuracy of 89.03%. The method provides new ideas for researchers to construct MIMIC database and provides more information for clinical research based on MIMIC database.
