Assessing Systemic Barriers to Veteran Health Using Systems Thinking: Tools for Community Assessment and Action

Every community has a hidden architecture of support that determines whether its members thrive or struggle. For the millions of people who have served in the military, this architecture is often fractured. Despite decades of federal investment and a vast network of healthcare facilities, veterans continue to face disproportionately high rates of suicide, substance use, and chronic illness. The problem is not a lack of resources, but rather a lack of understanding about how those resources fit together. When a veteran leaves active duty, they step into a complex web of eligibility rules, cultural shifts, and social expectations that can either guide them toward care or push them away from it. Researchers have long known that health is shaped by more than just doctors and medicine; it is shaped by housing, jobs, and the feeling of belonging. To fix the system, communities need a way to see the invisible connections between these factors, to understand how a small barrier in one area can trigger a cascade of failure in another.

A team of researchers at the University of North Carolina at Chapel Hill set out to build a map of these connections. They did not simply survey veterans or review medical charts; they used a method called systems thinking to visualize the entire ecosystem of veteran health. Imagine looking at a city not just as a collection of buildings, but as a living network where traffic jams in one district cause gridlock in another. The researchers applied this same logic to veteran care, creating two specific tools to help communities see the whole picture. The first tool is a causal loop diagram, which acts like a flowchart showing how different parts of the system influence each other. The second is an iceberg model, which helps distinguish between the visible problems we see every day and the deep, hidden beliefs and structures that cause them. By combining these tools with insights from veterans, community leaders, and experts, the team produced a guide for action that moves beyond blaming individuals and instead targets the system itself.

The researchers began by gathering evidence from existing studies and then refined their findings through direct conversations with veterans and the people who serve them. They held focus groups and interviews across North Carolina, asking participants to look at their initial drafts and point out what was missing, what was confusing, and what felt true to their experience. This process of listening and adjusting ensured that the final maps reflected the reality of life for veterans, not just the theory of policy. The result was a detailed visualization of fourteen different feedback loops, or cycles, that drive veteran health outcomes. Some of these cycles are vicious, where one problem makes another worse. For example, a veteran might struggle with a service-connected injury, which leads to frustration and risky behavior. That behavior can result in a legal issue or a discharge status that disqualifies them from receiving care, which in turn leaves their injury untreated, leading to even more frustration and risk. The researchers found that these loops often trap veterans in a cycle of disengagement, where the system itself seems designed to keep them out.

One of the most significant discoveries was how deeply military culture influences a veteran's ability to seek help. The researchers found that the very traits that make a soldier effective—self-reliance, stoicism, and a strong sense of duty—can become barriers to health once they return to civilian life. Many veterans feel that asking for help is a sign of weakness, a belief reinforced by the military environment. This mindset creates a feedback loop where veterans avoid care until their condition becomes critical, at which point they are often too overwhelmed to navigate the complex enrollment process. The study also highlighted a critical gap in the transition period. The programs designed to help veterans adjust to civilian life are often too brief, too crowded with information, or delivered in a way that feels impersonal. As a result, many veterans leave the military without understanding how to access the benefits they have earned, or they assume they are not eligible when they actually are.

The researchers used the iceberg model to organize these barriers by how difficult they are to change. The tip of the iceberg represents the events we see: a veteran in crisis, a denied benefit claim, or a suicide attempt. Just below the surface are the trends, such as a steady rise in medical mistrust or a growing number of veterans turning to private care because the public system is too slow. Deeper still are the structures, like the complex rules for eligibility or the way third-party contractors are hired to evaluate disabilities. At the very bottom, anchoring the entire system, are the mental models: the unspoken beliefs that veterans are undeserving of care, or that the military should handle its own problems without outside help. The study found that while it is easier to address the events at the top, such as providing food vouchers or immediate counseling, lasting change requires shifting the deep structures and beliefs.

To address these deep barriers, the researchers identified ninety-three specific "leverage points," or places where a small change could create a large impact. These points range from simple actions, like training community doctors to recognize the signs of veteran trauma, to major policy shifts, such as simplifying the rules for enrolling in healthcare. One powerful leverage point identified was the role of the "battle buddy" or peer advocate. The study found that when a veteran faces a denial of benefits, having a supportive peer who can guide them through the appeal process can break the cycle of hopelessness. Similarly, the researchers noted that community organizations, such as local veteran service groups, are often misunderstood by the veterans they try to help. Many veterans assume these groups are part of the government and are frustrated by them, not realizing they are independent allies. Clearing up this confusion and building trust between these groups and the veterans they serve was identified as a crucial step.

The study also examined the financial and structural pressures within the healthcare system itself. The researchers found that the system often reacts to high costs by cutting back on services, which paradoxically makes the problem worse. When the public system reduces its capacity, veterans are forced to seek care in the private sector, which is often more expensive and less familiar with veteran-specific needs. This drives up overall costs and leads to further cuts, creating a cycle that erodes the quality of care for everyone. The researchers suggested that the solution lies in viewing the use of veteran healthcare not as a burden, but as a collective benefit that supports the entire community. By reframing the narrative, communities can encourage veterans to use the services they need, which in turn stabilizes the system and improves care for all.

Ultimately, this research provides a new way for communities to think about veteran health. Instead of viewing the challenges as a list of separate problems to be solved one by one, the tools developed by the researchers show how these problems are interconnected. The causal loop diagrams and iceberg models serve as a shared language for veterans, policymakers, and community leaders to discuss the root causes of poor health outcomes. The study does not claim to have solved the crisis of veteran health, but it offers a clear path forward. By understanding the feedback loops that trap veterans and identifying the leverage points where change is possible, communities can move from reacting to crises to preventing them. The work suggests that the most effective way to support veterans is not just to build more hospitals, but to repair the social and structural fabric that connects them to the care they need.
