Transportability, calibration drift, and recalibration of intraoperative mean arterial pressure trajectory phenotypes for prolonged postoperative length of stay.

International journal of medical informatics - 15 Nov 2026

Ren Jingzhuo, Xue Zhaoping

Abstract excerpt

BACKGROUND: High-frequency intraoperative monitors support medical-informatics research, but temporal blood-pressure data are often reduced to threshold summaries. OBJECTIVE: To evaluate the transportability of a relative-time mean arterial pressure (MAP) trajectory representation and associated prediction models across MOVER and VitalDB. METHODS: We derived K = 4 phenotypes from 100-bin MOVER trajectories,...
