Outline of Final Research Achievements

The Integrated Palliative care Outcome Scale (IPOS) is a patient-reported outcome scale that is widely used internationally in palliative care. In Japan, it is used for cancer patients.Then,the purpose of this study is to examine the reliability and validity of IPOS for non-cancer elderly people. With the approval of the Tohoku University Graduate School of Medicine Ethics Committee, an expert panel considered the application of IPOS to non-cancer patients. After exmination a pilot study, this survey was started with a revised IPOS. Although the survey was difficult due to COVID-19, by the end of fiscal year 2022, 223 cases had been collected,which was the target number. Analysis confirmed that IPOS has reliability and validity in non-cancer elderly people as well.

Academic Significance and Societal Importance of the Research Achievements

IPOS(Integrated Palliative care Outcome Scale)は慢性心不全、COPD、慢性肝不全、腎不全、神経難病、フレイルなどの非がん患者を対象非がん高齢者への使用で十分な信頼性・妥当性を有することを示すことができた。ただし、IPOSの患者評価と医療者評価の相関はあまり高くなく、それは患者報告型アウトカムの重要性を裏付ける結果と考察した。非がん患者に対する表面・内容妥当性および実行可能性について日本語論文、信頼性・妥当性に関して英語論文として投稿し、どちらも採択された。使用者用マニュアルもあるため、緩和ケアを必要とする高齢者に広く使用されることが期待される。
