Outline of Final Research Achievements	Continuous and timely assessment of pathological conditions is necessary for elderly people with advanced medical needs to be able to care for themselves safely at home. In order to realize the smart home care based on the concepts of "non-invasive”, “non-restrictive," "continuous" and "real-time”, this study aimed to establish liquid assessment technologies using biosensors to capture pathological changes and to predict abnormalities. This project targeted chronic dehydration, aspiration pneumonia, infection of pressure injury, and urinary tract infection, which are caused by and threaten the daily life of the elderly. The studies were conducted according to the following steps: (1) search for biomarkers, (2) proof of the causal relationship between biomarkers and symptoms, (3) establishment of non-invasive measurement methods for biomarkers, and (4) verification the reliability and validity of the biomarker measurement methods.

Academic Significance and Societal Importance of the Research Achievements	地域包括ケアシステムの時代に、高齢者は複数の疾患を有し複雑な病態を呈するため、高度な医療ニーズを抱えながら在宅で療養している。本研究で実現を目指すスマートホームケアは、ベッドセンサ、環境センサ、およびバイオセンサを用いた継続的かつ適時的な病態アセスメントによる病態の変化や異変の予兆を捉え、適切な医療ケアに繋げる者であり、在宅療養高齢者が安心して日常生活を送ることに繋がり、ひいては地域包括ケアシステムの確立に寄与するものと考えられる。
