Paediatric Critical Care Implementation in Lower-Resource Settings: Application of Community-Based Group Model Building
This study utilized a community-based group model building workshop with 27 stakeholders at a hospital in Malawi to identify barriers, facilitators, and develop a shared vision for establishing a high-quality Paediatric Intensive Care Unit in a low-resource setting.

In many parts of the world, a child arriving at a hospital with a severe illness faces a stark reality: the medical staff are skilled and dedicated, but the tools and systems needed to save them are often missing. This gap is most acute in low-resource countries, where the burden of critical sickness is high, yet the specialized units designed to monitor and treat these patients are scarce or non-existent. When such a unit is finally built, the challenge does not end with the construction of the building or the delivery of equipment. The true difficulty lies in making the unit work as a living part of a complex hospital system. A new hospital wing does not exist in a vacuum; it draws staff, supplies, and attention away from other departments, potentially creating new problems even as it solves old ones. To understand how these systems function, researchers look at the relationships between people, resources, and rules, recognizing that a change in one area sends ripples through the entire organization.
In Malawi, a team of international and local doctors and researchers faced this exact complexity as they helped establish the country's first standalone pediatric intensive care unit at the Queen Elizabeth Central Hospital in Blantyre. The unit, located within the Mercy James Center for Paediatric Surgery and Critical Care, opened its doors in 2017 with six beds, modern monitors, and ventilators. However, the team knew that simply having the technology was not enough. They needed to understand the invisible forces that would determine whether the unit could survive and thrive. To do this, they turned to a method called group model building. This is a process where a diverse group of people—doctors, nurses, administrators, and community representatives—sit down together to map out how their hospital works. Instead of a single expert dictating the plan, the group draws a picture of cause and effect, showing how hiring more staff might improve patient care, or how a shortage of supplies might lower morale, which in turn might cause more staff to leave.
The researchers gathered 27 participants representing every part of the hospital system for a two-day workshop. Their goal was not to lecture the staff, but to listen and to build a shared understanding of the challenges they faced. The group began by listing the things that helped the unit succeed and the things that held it back. They then worked together to connect these factors, creating a visual map of the hospital's dynamics. This map revealed that the system was full of feedback loops, where one action led to a result that either strengthened or weakened the original action. For instance, the team saw that as more patients arrived, the gap between the number of staff needed and the number available grew larger. This increased the workload for the existing nurses, which led to more mistakes and lower quality of care. Over time, this decline in care could damage the hospital's reputation, causing fewer families to bring their sick children there, which would eventually reduce the workload but at the cost of the unit's purpose.
The workshop also uncovered a more subtle tension. The new intensive care unit was a high-resource environment within a hospital that generally had very few resources. The group realized that pouring money and advanced equipment into this one unit could create a sense of unfairness among staff in other departments who felt their own units were being neglected. This perceived gap could lead to frustration and a breakdown in communication between the intensive care team and the rest of the hospital. Furthermore, the team noted that the rapid introduction of new medical procedures and the presence of international staff, while bringing valuable skills, sometimes widened the gap in knowledge between local and visiting teams. This created a cultural and linguistic divide that made it harder for everyone to work together effectively. The participants agreed that simply training staff was not enough; they needed strategies to keep staff in their jobs and to ensure that the new unit supported, rather than drained, the rest of the hospital.
By the end of the workshop, the group had moved from a collection of individual worries to a single, shared picture of their reality. They identified specific points where they could intervene to break negative cycles and strengthen positive ones. They proposed practical steps, such as creating dedicated spaces for staff to discuss patient cases, rotating nurses between the intensive care unit and other departments to share knowledge, and developing a standardized curriculum for training that accounted for the local context. The process itself proved to be a powerful tool. It gave a voice to staff members who rarely had the chance to speak in planning meetings and allowed them to see how their daily work fit into the larger system. The researchers found that this participatory approach was feasible even in a setting with limited resources and that it successfully created a common language for discussing complex problems.
The study suggests that building a pediatric intensive care unit in a low-resource setting is not just a matter of construction and equipment, but of understanding the human and organizational dynamics that surround it. The group model building process allowed the stakeholders to see that their challenges were interconnected and that solutions required cooperation across the entire hospital. While the workshop did not solve every problem, it provided a clear path forward. It showed that when a diverse group of people can map out their shared reality, they can develop a vision for the future that is grounded in their actual experiences. The next step for the team is to turn these insights into concrete actions that will help the unit function smoothly and sustainably, ensuring that the children of Malawi receive the critical care they need.
