Developing a cross-validation tool for evaluating economic evidence in rapid literature reviews.

Background: Rapid economic reviews efficiently summarize economic evidence. However, reporting main findings without assessing quality and credibility can be misleading. The objective of this study was to develop a rapid cross-validation screening tool to evaluate economic evidence when conducting rapid economic literature reviews. Methods: This article outlines our reasoning and the theoretical concepts for developing the screening tool. Results: This cross-validation tool is a qualitative approach under a Bayesian framework that uses prior health economic evidence to gauge the credibility of the rapid economic review's findings. This article describes an application of this tool and highlights practical considerations for its development and deployment. Conclusion: This tool can provide a valuable screening instrument to evaluate the quality and credibility of the economic evidence.
