We believe that systems thinking and complexity science can be transformational in global health by increasing local capacity and shared learning, and minimizing unintended consequences.
Systems Thinking is a novel, transformational way of thinking about and approaching health. In the past we have witnessed tremendous successes – such as the eradication of small pox and the treatment of diarrhea with oral re-hydration solutions – by considering one aspect of health in isolation, whether it be a specific patient, disease, project, or policy. However, the real world is very complex, and our fragmented approach has too often resulted in unintended consequences such as dependency, inefficiencies, and inequities.
Systems Thinking is based on the idea that when all stakeholders and their interactions are considered as a whole, we can better understand health problems than we can when only viewing each part in isolation. Such an approach means that we must consider economic, political, and social factors – factors that might seem unrelated to health. Also, since health challenges are complex, and solutions differ depending on time and place, we cannot impose a top-down plan of action and expect predictable, positive results all the time. From a systems thinking perspective, it is often best to facilitate an environment where local people and communities self-organize to improve health, leading to positive results that health planners might not have even imagined. Systems Thinking provides the principles, approaches, and methods to rethink our basic assumptions about health, and unite to create the future that we want.
