Clinical Research Support Activities in Core Clinical Research Hospitals Throughout Japan.

We evaluated the current status of supporting activities in core clinical research hospitals across Japan using the Japan Registry of Clinical Trials (jRCT) data given the lack of previous research objectively investigated supporting activities for clinical trials in core clinical research hospitals throughout Japan. Briefly, our findings showed that despite the officially supposed cooperation scheme, core clinical research hospitals have not been the primarily selected contractor for clinical research supporters. Considering that core clinical research hospitals are designated spearhead physician-led clinical trials and are responsible for ensuring the quality of such trials, there is a need to determine why the officially supposed cooperative scheme between core and non-core hospitals are still not established in Japan in order to increase the development and quality of Japanese clinical research with maximum efficiency moving forward.
