Public Health Nursing Disaster Preparedness and Shelter Readiness: A Statewide Needs Assessment

When a disaster strikes, whether a wildfire, an earthquake, or a flood, the immediate need is often for a safe place to sleep, eat, and receive medical attention. These temporary havens are called shelters, and they are where the most vulnerable people in a community—those without homes, the elderly, or those with chronic illnesses—go to wait out the danger. Keeping these shelters running requires more than just cots and food; it requires skilled health workers who can manage the flow of people, treat minor injuries, prevent the spread of illness, and connect individuals with the care they need. In the United States, public health nurses are the specialists trained for this exact work. They are not the doctors who perform surgery in a hospital, but rather the experts who understand how to care for entire groups of people, navigate complex community needs, and bridge the gap between medical care and the reality of a crisis. As disasters become more frequent and severe, the ability of these nurses to step into a shelter and function effectively is a matter of public safety.

A recent study conducted in California sought to understand exactly how ready these nurses are for such a moment. The researchers, working with leaders from public health departments across the state, asked a simple but critical question: if a major disaster happened tomorrow, could the public health nurses in your area be sent to a shelter, and would they know what to do? The state of California is a useful place to ask this because it faces a wide variety of natural threats and has a large network of local health departments. However, unlike a military unit with a single, unified training manual, these local departments operate independently. Each one decides for itself how to prepare its staff, what training to provide, and how to organize its response. This lack of a single, statewide standard meant that while some nurses might be highly prepared, others might be sent into a crisis with little guidance or support.

To get a clear picture of the situation, the researchers gathered information from 23 local health jurisdictions. They did this in two ways: by holding a group discussion with nursing leaders at a professional conference and by sending out a detailed survey to the same group. The survey asked about the size of their nursing teams, what kind of training they had received, whether they had written plans for disaster response, and how confident they felt about sending their nurses into a shelter. The group discussion allowed the leaders to share their real-world experiences, the obstacles they faced, and the things that helped them succeed. The goal was not just to count how many nurses were available, but to understand the systems that either helped them or held them back.

The results revealed a significant gap between expectation and reality. While the vast majority of these local health departments, about 82 percent, said they would assign public health nurses to work in a disaster shelter, only a small fraction, just 20 percent, felt that their nurses were actually prepared to do the job. This suggests that while the plan exists on paper, the readiness to execute it is lacking. The researchers found that the difference between a jurisdiction that felt prepared and one that did not came down to a few specific, practical factors. The most powerful factor was having a dedicated nurse whose sole job was to coordinate disaster preparedness. In places where such a person existed, the readiness scores were much higher. Similarly, having written protocols—clear, step-by-step instructions on what to do—made a substantial difference. Jurisdictions with these written guides felt their staff was far better prepared than those without them.

Training also played a crucial role. The data showed that nurses who had received more than one type of disaster training felt significantly more ready than those who had only the basic, mandatory training. The most common training offered was a standard federal course on how to manage emergency commands, but the leaders noted that this was not enough on its own. They identified a strong need for additional instruction in specific areas like infection control, triage (the process of deciding who needs care most urgently), and the specific scope of work for a nurse in a shelter setting. Without this targeted training, nurses were left to figure out their roles in the chaos of a disaster, which is a risky proposition for both the nurses and the people they are trying to help.

Perhaps the most persistent challenge identified by the nursing leaders was a lack of clarity about what a public health nurse is actually supposed to do in a shelter. This confusion existed both within the health departments and among the external partners they work with, such as the American Red Cross. In some cases, other agencies would request nurses for tasks that did not match their training or legal scope of practice, leading to frustration and inefficiency. In other cases, the nurses themselves were unsure of their responsibilities. This ambiguity made it difficult to plan effectively. The leaders also pointed out that administrative hurdles, such as concerns about liability or union rules, often slowed down the process of getting nurses deployed.

Despite these challenges, the study highlighted several things that worked well. When local health departments had strong operational support, such as clear workflows, digital tools to manage staffing, and a repository of necessary forms and documents, their nurses were more ready. Collaboration was another key factor. Departments that worked closely with internal partners and external organizations like the Red Cross, and that participated in joint training exercises, reported better outcomes. The leaders emphasized that having a collaborative approach, where everyone understands each other's roles before a disaster strikes, is essential for a smooth response.

The study concludes that while California has a strong foundation of public health nurses who are willing to serve, the system supporting them needs improvement. The path forward involves creating a more standardized approach to training and planning across the state. The researchers suggest that sharing resources, such as a toolkit of templates, protocols, and training materials, could help smaller departments that lack the resources to develop their own. Furthermore, it is vital that public health nursing leaders are included in the highest levels of emergency planning, ensuring that their expertise shapes the response strategies from the beginning. By clarifying roles, providing consistent training, and fostering strong partnerships, the state can ensure that when the next disaster arrives, the nurses are not just present, but truly ready to protect the health of their communities.
