Bryan Farrow of OpenClinica examines how we should approach eligibility at the level of data management and workflow optimisation, offering some best practices as well as providing an example eligibility form that puts them into action. He identifies these as making eligibility a form, failing early (and cheaply), making sure your forms carry out the logic, and moving beyond ‘yes’ or ‘no.’ He concludes that consent and eligibility constitute the foundation of the study journey and that data managers and study operations professionals need to focus heavily on efficiency and quality of work.
