The ORRCA project (Online Resource for Research in Clinical triAls) aims to bring together published and ongoing work in the field of recruitment and retention research into searchable databases.
We are still updating the recruitment database with publications from 2018 and 2019 due to the large volume of literature in this field. Articles will be added periodically throughout the review process. An update of the retention database for 2020 and 2021 publications will be starting shortly. Authors are welcome to submit papers as soon as they are published. Retention database last update: 09/02/2022. Recruitment database last update 29/06/2022
If you use the ORRCA databases in your research, please reference either of the following papers in any reports or publications:
