Beyond the Hospital Walls. Health System Coordination and the Limits of Preparedness

In 2020 and 2021, some of our colleagues supported Ukraine's national COVID-19 response, working with field epidemiologists on outbreak investigation, contact tracing, and the rollout of digital tools to track transmission in real time.

It was valuable and necessary work. It was also a front-row seat to one of the most persistent problems in emergency response: the coordination gap.

Field epidemiologists and hospital leadership are, by necessity, focused on different things. The first ones map where the disease is going, while the hospitals must manage bed capacity, staff emergency departments, and make decisions about which services to suspend. Both are doing exactly what they should be doing, but when the communication between those two functions is insufficient, the consequences are felt by patients.

During a surge, that gap becomes particularly costly. A hospital receiving more critical cases than it can handle is not only a clinical problem of one particular hospital. It is exactly the situation where better information flow between what field teams are observing and what hospital leadership is acting upon can make the difference between a manageable surge and a system that stops functioning.

This is not unique to pandemics. The same coordination gap appears in mass casualty events, natural disasters, and infrastructure failures. The nature of the emergency may be different, but potential structural weaknesses remain the same.

Hospital preparedness cannot be separated from the broader health security picture. A hospital that is internally well-prepared but poorly connected to the system around it will still struggle when the pressure arrives from outside its walls.

Part of the challenge is structural. In a large-scale emergency response, different functions operate under different pressures, different reporting lines, and different definitions of success. Field epidemiologists are trained to follow the disease. Hospital managers are trained to manage capacity and continuity. Each is doing exactly what their role demands. The problem is not competence or commitment, but rather in the absence of a shared operational picture.

What this experience reinforced is that coordination cannot be reduced to procedures alone. Establishing a protocol for information sharing between field teams and hospital leadership is necessary, but rarely sufficient. What matters as much is the degree to which different parts of the response system are simply aware of what the others are doing. Not in a formal reporting sense, but in the sense of understanding the pressures, constraints, and decision logic that each function operates under.

That kind of mutual awareness is not built during an emergency. It is built before one, through joint exercises, cross-functional training, and the kind of horizontal communication that most organizations systematically underdevelop in favor of vertical reporting structures. When it exists, it doesn't magically eliminate coordination gaps, of course, but it makes them narrower. And it makes the people on either side of them better equipped to bridge them under pressure.
