Supply and Demand Constraints Generating Health Policy and Systems Research in Cambodia: A Qualitative Institutional Analysis
This qualitative institutional analysis of Health Policy and Systems Research (HPSR) in Cambodia identifies critical supply and demand constraints, including limited local capacity, low domestic demand for evidence, and donor dominance, which collectively hinder the generation of contextually relevant, evidence-informed health policies and underscore the urgent need for strengthened local ownership and resource allocation to ensure sustainable system learning.

Imagine a health system not as a single machine, but as a living, breathing community where doctors, hospitals, governments, and patients constantly interact. For this community to stay healthy, it needs to learn from its own experiences. It needs to ask questions, gather facts about what is working and what is failing, and then use those facts to make better decisions. This process of learning is called a "learning health system." At the heart of this learning is a specific type of investigation known as health policy and systems research. Unlike studies that simply test a new medicine, this research looks at the complex web of rules, organizations, and people that deliver care. It asks why a policy succeeded in one village but failed in another, or how a shortage of nurses affects patient safety. The goal is to turn raw data into clear, actionable advice that leaders can use to fix broken parts of the system. Without this kind of research, a country is like a driver navigating a foggy road with no map, making decisions based on guesses rather than evidence.
In Cambodia, a nation that has made remarkable progress in public health over the last few decades, researchers wanted to understand why this learning process is still struggling. They focused on the gap between the research being produced and the decisions being made by government officials. To find out what was holding the country back, a team of investigators conducted a series of in-depth conversations with fifteen key people. These included senior government officials who decide on health policies, researchers who generate the data, and leaders from international organizations that fund health projects. The team met with these individuals in Phnom Penh over two weeks in August 2024, asking them to describe their daily challenges, their needs, and the obstacles they face when trying to use evidence to improve the health system.
The researchers found that the system is stuck in a cycle of mismatch. On one side, there is a shortage of local capacity to produce high-quality research. The country lacks enough trained experts in fields like health economics and data analysis, and there is not enough money to train more or to hire them. When training does happen, it often fails to stick because the staff are too busy, or the lessons do not fit the local reality. Furthermore, the data that does exist is often incomplete or scattered. Health records are not always kept in a way that allows for easy analysis, and information from private clinics rarely reaches government planners. This means that even when researchers want to study a problem, they often cannot find the reliable numbers needed to understand it.
On the other side of the equation, there is a surprisingly low demand for this kind of research from the people who actually make the decisions. Government leaders often do not ask for studies before they launch new programs. Instead, they rely on their own experience, immediate needs, or the advice of international donors. When research is requested, it is often an informal favor between friends rather than a formal part of the planning process. This creates a situation where valuable studies sit on shelves, unread and unused, because no one in power has been trained to ask for them or knows how to use them once they arrive. The researchers noted that decision-makers sometimes find technical reports too difficult to understand, or they simply do not see the value in waiting for data when they feel they need to act right away.
A major factor complicating this picture is the heavy reliance on foreign donors. For many years, international organizations have funded a large portion of Cambodia's health research. While this has brought in money and expertise, it has also meant that the research agenda is often set by outsiders rather than by Cambodian leaders. Donors tend to focus on specific diseases they are interested in, such as malaria or tuberculosis, while local leaders are increasingly worried about rising rates of diabetes and heart disease. As a result, the research being done often does not match the problems the country is trying to solve. When a donor leaves or changes their priorities, the research stops, leaving local institutions without the skills or resources to continue on their own. The study found that this dependence has created a disconnect where the evidence generated is not always useful for the country's own long-term goals.
The researchers also discovered that the different parts of the health system do not talk to each other well. Government departments often work in isolation, keeping their data to themselves. A department responsible for training doctors might not share its information with the department that manages hospital staffing, even though both need to know the same facts to do their jobs. This fragmentation means that the full picture of the health system is never clear, making it impossible to solve complex problems that require cooperation across different sectors. The lack of a central organization to bring everyone together and translate complex research into simple, usable advice further widens the gap between what is known and what is done.
Despite these significant hurdles, the study did not find a hopeless situation. The people interviewed showed a genuine desire to improve. Some researchers were finding creative ways to extract useful local information from donor-funded projects, and some officials were beginning to see the value of prevention over just treating sickness. However, these efforts are currently driven by individual passion rather than by a strong, permanent system. The researchers concluded that for Cambodia to truly learn and adapt, it needs to move beyond relying on the goodwill of individuals or the changing priorities of foreign donors. The country needs to build its own permanent structures for research, train its own experts, and create a culture where asking for evidence is a standard part of making decisions. Without these changes, the health system will remain vulnerable, unable to learn from its own experiences or to sustain its progress when the external support eventually fades.
