Outline of Final Research Achievements

The present study aimed to identify advanced warning signs of aspiration pneumonia by collecting basic demographic information, biological data, and facial coordinate data of patients with dysphagia and extracting relevant factors and features (e.g., oxygen saturation [SpO2], fingertip plethysmography, lip/jaw coordinates) to develop a monitoring technique that detects signs of aspiration pneumonia via machine learning.
Attempts were made to collect the following information: basic information; FIM; vital signs; biosignal monitoring (SpO2, fingertip plethysmography, coordinates of the lips, corners of the mouth, and jaw via face tracking). However, the coronavirus disease 2019 pandemic resulted in a delay in beginning the examinations. Nevertheless, the authors are currently partnered with a facility where they are conducting the survey and are in the process of data collection and analysis.

Academic Significance and Societal Importance of the Research Achievements

観察によって得られた生体情報を蓄積して、判別式の的中率を向上させ、機械学習によって最適な特徴量選択することができれば、看護実践において有効なモニタリング手法の開発につながる。このモニタリング手法の活用により、摂食嚥下障害患者の安全な経口摂取に向けた、エビデンスに基づく援助計画の立案につながると同時に、安全で、かつ、積極的な摂食嚥下リハビリテーションが可能となる。
