Area of Science:
- Social Media Analytics
- Network Science
- Emergency Medicine
Background:
- Twitter is increasingly popular in emergency medicine (EM).
- Identifying influential opinion leaders on Twitter is crucial for understanding EM conversations.
- Little is known about the most influential emergency physicians (EPs) on the platform.
Purpose of the Study:
- To develop a methodology for identifying influential EPs on Twitter.
- To present a list of the most influential EPs on Twitter.
Main Methods:
- Analyzed 2,234 English-language EP Twitter accounts.
- Utilized NodeXL software for network analysis.
- Ranked EPs using in-degree, eigenvector, and betweenness centrality measures.
Main Results:
- Identified 142 unique influential users out of 300.
- Found 61 EPs ranked in the top 100 across all three centrality measures.
- These 61 users are identified as the most influential EM Twitter users.
Conclusions:
