Twenty-Five Years After 9/11 — Lessons from the World Trade Center Health Program
Paper examines 9/11-related health outcomes and lessons learned in the quarter century since the disaster.

The Journal of the American Medical Association (JAMA) today published “Twenty-Five Years After 9/11 — Lessons from the World Trade Center (WTC) Health Program,” a paper by World Trade Center (WTC) Program staff that demonstrates robust outcomes in preventive care and chronic disease management in the quarter century since the events of September 11, 2001.
The paper reflects on the courage and sacrifice of those selfless responders who answered the call of duty, as well as those who lived, worked, or went to school or daycare in the New York City Disaster Area. It also provides insights on how the WTC Health Program makes a real difference in helping to improve quality of life and positive health outcomes among 9/11 responders and survivors enrolled in the Program.
The paper examines three key insights that have emerged from the long term follow up of the 9/11 impacted population:
- Disaster-related health effects are often chronic, dynamic, and involve multiple organs in the body.
- Individuals exposed to the 9/11 attacks have a greater prevalence of chronic conditions and poorer health-related quality of life compared to the general population. At the same time, those enrolled in the WTC Health Program have improved survival compared to those not enrolled, illustrating the connection between exposure-related risk and access to beneficial care.
- Integrated systems of care improve health outcomes. Effective approaches require ongoing, connected systems of care and research. In this way, the Program provides a model for how health systems can respond to such events, not only in the immediate aftermath but also in the long term.
The WTC Health Program’s mission includes evaluating health outcomes experienced by the 9/11 impacted population to identify ways to improve their treatment and care. Program members contribute to these efforts by participating in research studies. Findings from these efforts can help others who may face similar health exposures in the future.
