Outline of Final Research Achievements |
Most patients requiring ventilatory management in ICUs and hospital wards are associated with sputum production. Inflammation of the airways and lungs and various other stimuli increase the viscosity of the sputum, impairing expectoration and sometimes causing asphyxia due to airway obstruction. In addition, the residual sputum in the airways creates an environment for bacterial growth, causing infection and inflammation. Therefore, appropriate sputum care based on accurate assessment is essential, but at present, the mainstream is for healthcare professionals to assess sputum subjectively by visual observation. As a result of a survey of intensive care unit nurses, it was found that there are large individual differences in sputum viscosity evaluation, there is no established method for sputum evaluation in educational courses, and there are few studies on standardization of sputum evaluation in previous research.

Academic Significance and Societal Importance of the Research Achievements |
喀痰評価の現状を明らかにした。また喀痰評価の標準化を構想しており、これは看護に関わるケアの根幹である喀痰の物理学的かつ視覚的な評価の課題に着手する初めての研究である。医療従事者の主観で判断していた、加温加湿や排痰ケア、薬剤使用などの開始基準や効果判定など、多岐にわたる根拠を示すための研究に繋がる。また、疾患の早期発見、患者予後の改善に繋がる可能性がある。今後、看護師の人手不足、急性期病床削減による医療提供レベルの低下が懸念されている。また、在宅医療へのシフトにより患者家族によるケアが増えていくことから、喀痰評価の標準化は急務である。
