Expert consensus refers to the collective agreement among a group of specialists in a particular field regarding a specific issue or topic. This agreement is often reached through discussions, reviews of existing research, and evaluations of evidence. It serves as a guideline for best practices and decision-making in various domains, such as medicine, science, and policy. In many cases, expert consensus is formalized in documents like clinical practice guidelines or position statements. These documents help practitioners and stakeholders understand the prevailing views on a subject, ensuring that decisions are informed by the latest knowledge and expertise available.
