Validation and Clinical Application of the Japanese Version of the Patient-Reported Experience Measures for Intermediate Care Services: A Cross-Sectional Study.

Older adult patients account for 70% of all hospitalized patients in Japan, and intermediate care based on patient-centered care (PCC) that ensures continuity and quality of care at the interface between home services and acute care services and restores patient's independence and confidence is necessary for them to continue living independently. At present, no concept of intermediate care is established in Japan, and the implementation of PCC has been delayed. Thus, in this study, a Japanese version of the intermediate care evaluation index (patient-reported experience measure (PREM)) was created on the basis of the original PREM developed in the UK, and data in wards with intermediate care functions in Japan were collected to confirm internal consistency and validity from 2020 to 2022. The Japanese version of PREM was found to have a factor structure with two potential factors. Given the clear correlation with the shared decision-making evaluation index, which is the pinnacle of PCC, the theoretical validity of the Japanese version of PREM, which is based on PCC as a theoretical basis, was confirmed.
