In this time of dynamic, uncertain, complex, and ambiguous health challenges at all levels worldwide, systems thinking, as it pertains to health, is critically needed. As described in our book, Health Systems Thinking: A Primer, systems thinking has gained wide acceptance in management, medical, and social sciences, including the domains of healthcare and public health. Increasingly, we also see its embrace in clinical practice, public policy, and health professions education. It has been advocated by the World Health Organization, implemented at the Centers for Disease Control and Prevention, promoted by the American Medical Association, and utilized widely at the National Institutes of Health. Currently, the accrediting commissions within public health, health administration, and nursing are including systems thinking as part of the core competencies in their respective fields. Likewise, in medicine, we are seeing health systems science being added to medical school curricula.
What Systems Thinking Does
Systems thinking challenges health leaders and clinicians to assess the interactions and interdependencies among elements in a system and seek out opportunities to generate sustainable solutions based on a deeper understanding of a given system. This typically follows a systematic analysis of root causes of problems and inefficiencies. Furthermore, systems thinking focuses on nonlinear assumptions about human behavior and feedback loops to determine a system’s behavior over time, thus finding leverage points to create more reliable and innovative health systems that adapt to achieve desired goals. The theories, concepts, and methods of systems thinking are suited to a myriad of health settings and professions, organizational cultures, and policy challenges.
A Worldly Perspective
On April 16, 2018, Time Magazine interview with Bill Gates, founder of Microsoft and Co-President of the Bill and Melinda Gates Foundation, Mr. Gates made the following statement about systems, “Modernity is a miracle of systems. Jonas Salk was an amazing scientist, but he isn’t the only reason we’re on the doorstep of eradicating polio—it’s also thanks to the coordinated vaccination effort of health workers, NGOs, and governments. We miss the progress that’s happening right in front of us when we look for heroes instead of systems. If you want to improve something, look for ways to build better systems.”
Overview of the Primer
Unfortunately, academic programs do not have sufficient learning materials on this topic to give students the requisite knowledge expected of the next generation of health professionals. This Primer addresses the void by empowering its readers with a greater understanding of this important and timely topic while increasing appreciation for the tremendous potential and the urgent necessity of systems thinking.
