Outline of Final Research Achievements

The present study sought to determine how the relationship between patient severity and length of interaction in the ICU can vary. 76 ICU staff members participated over a 4-week period, with each staff member working an average of 160 hours. 117 patients stayed in the ICU on Day 1, when the length of interaction and the SOFA score During the observation period from Day 1 to Day 10, the number of patients who stayed in the ICU gradually decreased due to discharge or death.

Academic Significance and Societal Importance of the Research Achievements

患者の重症度は、ICU初日と7/8日目の時間的な関連において、ICU医療従事者間の相互作用に影響を与える重要な役割を果たす可能性が示唆された。医療従事者のコミュニケーションや職場環境の改善が患者重症度に影響を与える可能性がある。
