Anna Kearney is a Trials Methodology researcher within the Clinical Trials Research Centre at the University of Liverpool. Over the last 6 years she has undertaken a number of methodological research projects, predominantly investigating the recruitment and retention of participants in Clinical Trials. At present she is coordinating a team of over 20 reviewers from across five nations as part of the ORRCA/ ORRCA2 project. ORRCA (www.orrca.org.uk) is a free, online, searchable, resource aimed at helping trial teams and methodologists navigate literature on recruitment and identify effective recruitment strategies relevant to different types of trials. Thousands of articles are currently being reviewed in order to update the resource and to extend it to include retention research.
