Outline of Final Research Achievements

We developed the Respiratory Distress Observation Scale (RDOS), a Japanese version of an objective dyspnea rating scale that can be used not only in intensive care units but also in palliative care and patients with impaired consciousness, without requiring self-report. The RDOS has been evaluated for scientific validity and reliability, and is now available for objective dyspnea assessment in Japan. In addition, we compared the diagnostic characteristics of the IC-RDOS and MV-RDOS. In addition, we investigated the association between RDOS and inspiratory effort (P0.1) and prognosis of ventilated patients, and found a weak negative correlation.

Academic Significance and Societal Importance of the Research Achievements

日本の医療機関等において、意識障害等により訴えられない患者等の呼吸困難を評価可能とする一連の研究を行なったことが本研究の社会的意義として高い点である。加えて、ICUや人工呼吸療法中などの患者に特化したRDOSとの比較を行い集中治療室でどの様なツールを用いるべきかを下記らかにした。また、呼吸困難は、呼吸努力を強め肺損傷を引き起こすリスクがあるが、この点に関する基礎的な資料を提供している。
