본 논문에서는 MIMIC-IV(Medical Information Mart for Intensive Care) v2.0 데이터를 이용한 시계열 데이터의 정제 및 가공 방법을 제안한다. 더불어 해당 가공법을 기반으로 정제한 데이터셋을 활용하여 구축한 기계학습 기반의 욕창 조기 경보 시스템을 통해 해당 가공 방법의 유의성을 검증하였다. 구현된 욕창 조기 경보 시스템은 병변이 발생하기 전 12, 24시간에 미리 의료진에게 경보를 주는 시스템이다. 전자의무기록(Electronic Medical Record; EMR) 시스템과 연동하여 실시간으로 환자의 욕창 발생 위험도를 의료진에게 알려 중환자 의사결정을 지원하고, 나아가 효율적인 의료 자원 배분을 가능하게 한다. 여러 기계학습 모델 중 GRU 모델을 사용하였을 때, AUROC 평가지표를 기준으로 발생 전 12시간이 0.831, 24시간이 0.822로 가장 좋은 성능을 보였다.

This paper proposes a method of refining and processing time-series data using Medical Information Mart for Intensive Care (MIMIC-IV) v2.0 data. In addition, the significance of the processing method was validated through a machine learning-based pressure ulcer early warning system using a dataset processed based on the proposed method. The implemented system alerts medical staff in advance 12 and 24 hours before a lesion occurs. In conjunction with the Electronic Medical Record (EMR) system, it informs the medical staff of the risk of a patient's pressure ulcer development in real-time to support a clinical decision, and further, it enables the efficient allocation of medical resources. Among several machine learning models, the GRU model showed the best performance with AUROC of 0.831 for 12 hours and 0.822 for 24 hours.
