Nurses' Core Competency in Cross-Departmental Care Under the Hospital-Wide Bed Sharing Model: A Cross-Sectional Study

Hospitals are vast, complex machines where the most critical resource is often a simple bed. For decades, the standard way to manage these beds has been to keep them locked within specific departments. A patient with a broken leg stays in the orthopedic ward; a patient with pneumonia stays in the respiratory unit. This system works well when demand is predictable, but it breaks down when the flow of patients becomes erratic. In many places, some wards are overflowing while others sit nearly empty, creating a structural imbalance where available beds exist but cannot be reached by the patients who need them. To fix this, some hospitals have begun to break down these walls, creating a "hospital-wide bed sharing" model. In this system, a bed is no longer the property of one department but a shared resource for the entire hospital, allowing patients to be moved dynamically to wherever there is space. While this approach has successfully reduced waiting times and increased bed usage, it fundamentally changes the daily reality for the nurses who care for these patients. Instead of mastering one specific type of illness, nurses must now be ready to care for anyone, anywhere, often in units where they have never worked before.

Researchers at Peking University First Hospital in Beijing set out to understand how this shift affects the nurses themselves. In 2024, the hospital began piloting this new model, and by late 2025, a team of researchers surveyed 710 nurses to see how they were coping. They wanted to measure "core competency," which in this context means the specific skills and confidence a nurse needs to care for patients outside their usual specialty. They also looked at how well these nurses communicated with other teams and whether the stress of this new environment was affecting their mental well-being. The study was designed to find out if the nurses were truly ready for this new way of working or if the system was asking more of them than they could handle.

The results revealed a surprising gap between what nurses felt they could learn and what they felt they could actually do. On average, the nurses scored moderately high on their overall ability to handle cross-departmental care, but when the researchers broke the scores down, a clear pattern emerged. The nurses rated their ability to learn and grow in their profession very highly. They felt confident in their desire to improve and their capacity to teach themselves new things. However, when it came to the actual practice of nursing patients from different departments, their scores were the lowest of all the categories. This suggests that while the nurses are eager and motivated to adapt, they feel less prepared for the immediate, hands-on reality of treating unfamiliar patients. It is a situation where the willingness to grow has outpaced the clinical readiness to act.

The study also identified what actually drives a nurse's success in this new environment. The most powerful factor was not how many years of experience a nurse had, nor their age or their job title. Instead, the strongest predictor of a nurse's competence was the quality of communication within their team. Nurses who felt they could transfer information clearly and coordinate effectively with doctors and other staff from different departments performed significantly better. This finding suggests that the key to making bed sharing work is not just hiring experienced staff, but building strong, structured systems for sharing information. If a nurse knows exactly how to hand over a patient's story to a team in a different wing, they are far more likely to succeed, regardless of how long they have been a nurse.

Another critical discovery was about the nature of experience. The researchers found that simply rotating through different hospital units helped nurses, but only up to a point. Nurses who had rotated through one or two different units saw a significant jump in their skills compared to those who had never rotated. However, rotating through three or more units did not provide a proportional increase in skill. Similarly, caring for a very high number of cross-departmental patients in a single month was linked to better performance, but caring for a moderate number did not show the same benefit. This indicates that there is a threshold of exposure needed to build competence. Once a nurse has had enough initial experience to understand the basics of working across departments, simply adding more time or more patients does not automatically make them more skilled. The most efficient way to build this skill set appears to be through early, well-structured exposure rather than long, drawn-out periods of uncertainty.

The study also highlighted the emotional cost of this system. The researchers measured anxiety levels among the nurses and found a clear link: higher anxiety was associated with lower competency. When nurses felt anxious, their ability to perform cross-departmental care dropped. This makes sense, as caring for patients in unfamiliar settings requires navigating unknown medical histories and different workflows, which can be a significant source of stress. The findings suggest that for a hospital-wide bed sharing model to work, it cannot rely on the nurses' resilience alone. The system must include psychological support and stress management to help nurses manage the uncertainty of their new roles. Without this support, the very stress that comes with the new model could undermine the skills the hospital is trying to build.

Ultimately, the research paints a picture of a workforce that is willing and capable but needs the right support structures to thrive. The nurses are not failing; rather, the system is revealing a mismatch between their motivation to learn and the practical tools they have to apply that learning. The study concludes that for hospitals to successfully implement this model, they must focus on three things: building robust communication channels that connect different teams, designing rotation programs that provide a clear, early threshold of experience, and offering psychological support to manage the anxiety of the unknown. By addressing these specific areas, hospitals can ensure that the bed sharing model works for the patients without breaking the people who care for them.
