Sarra De Valence - Senior Manger of CER Writing on Systematic Literature Search and Screening

On this episode of Chasing Compliance, host Jamie Hijmans and Sr. Manager Sarra De Velance discuss systematic literature search and screening. They discuss the importance of robust literature searches and screening processes and the consequences of poorly constructed search terms. Sarra describes her process and provides tips for developing robust searches. They discuss the pitfalls and benefits of using search operators such as Medical Subject Heading (MeSH) terms and not operators, as well as where to look for help if you get stuck. Sarra also provides insight into surmounting the challenges of literature screening, including developing comprehensive and clear inclusion and exclusion criteria, common errors made during literature screening, and best practices for creating rigorous, reproducible literature screening processes. As always, they wrap up the episode with Favorite Fridays.
