Overview:

TEFCA establishes a nationwide framework for health information exchange through designated QHIN networks, but I noticed that participation and network density vary by states. So this map lets us see TEFCA participation coverage throughout the US which can help identify potential bottlenecks. These differences can have downstream effects on clinical workflows, emergency department record retrieval, and administrative cost.

Key Problem: Which states have uneven TEFCA participation density?

TEFCA was essentially made for systems to easily exchange sensitive health information but participation isn’t uniform across these networks. Some states can be seen having low overall participation while others rely heavily on a single QHIN. This difference can be a potential problem for this infrastructure because it may increase chances for errors like duplicate testing or delayed record retrieval. But I think it’s still important to know that participation doesn’t entirely reflect usage or volume and that this analysis focuses on the structural coverage instead of clinical outcomes.
