A new study featuring NASHIA staff as first author evaluates whether national online surveys can effectively measure how often intimate partner violence (IPV) results in traumatic brain injury (TBI). Analyzing responses from over 8,700 U.S. adults in the CDC's Rapid Surveys System, researchers found that an estimated 6.0% of all U.S. adults have experienced an IPV-related TBI in their lifetime, demonstrating that internet panel surveys are a viable method for capturing the scope, symptoms, and medical response to these injuries. Overall, the results indicate that millions of Americans - disproportionately women - are affected, yet the vast majority go without a medical evaluation due to underestimating the severity of the injury or being actively blocked from seeking care by an abusive partner.

A new study featuring NASHIA staff as co-author examined the nearly 69,000 TBI-related deaths in 2023 and found important differences by age, sex, race and ethnicity, and cause of injury. Overall, suicide and unintentional falls were the leading contributors to TBI-related deaths, while older adults, males, and American Indian/Alaska Native people experienced the highest rates. The findings also show that the causes of TBI-related deaths vary considerably across different populations.

There are myriad data sources available to brain injury programs. These sources can help:

• Determine just how common brain injury is in your state.

• Discover how many people are living with long-term effects of brain injury.

• Assist in program and resource planning.

However, sometimes it is difficult to know where to start. Which types of data are most common? How can you access them? How can you use the different types? This short guide is meant to help you answer some of those questions to ensure that the data that are available to you are making a difference.
