The Use of patient Reported Outcome Measures for Rheumatoid Arthritis in Japan: A Systematic Literature Review

The Open Rheumatology Journal 28 Apr 2017 REVIEW ARTICLE DOI: 10.2174/1874312901711010043



Patient-reported outcomes (PRO) obtained through routine medical care may identify patients’ day-to-day burden and help tackle the disease from the patients’ perspective. However, there is a paucity of information regarding the availability of PRO data and PRO tools for rheumatoid arthritis (RA) in Japan.


We reviewed the literature on PRO data availability and to identify PRO measures implemented in Japan for RA patients.


We conducted a systematic literature review using ICHUSHI and the PubMed databases on PRO measures for RA published from January 2011 to August 2015 in Japan.


After removing duplicates, 2423 manuscripts were found. From these, 100 manuscripts were included for review and analysis. We found 29 PRO tools that were used to assess various domains of health such as general well-being, pain, functionality, and fatigue. More than 90% of the studies utilized PRO tools for research purpose. Only one study reported PRO tool implementation in the routine medical care.


The importance of PROs is recognized in Japan. PRO tools varied significantly and were mostly used for research purposes, while reports on the use of PRO measures in routine medical care were limited. Despite the awareness of PROs in the research community, unmet needs remain among RA patients in Japan. Further work is needed to investigate ways in which PROs can better reflect these unmet needs and be utilized in routine medical care.
