Diane T. FinegoodA Food Systems and Public Health conference was convened in April 2009 to consider research supporting food systems that are healthy, green, fair, and affordable. We used a complex systems framework to examine the contents of background material provided to conference participants. Application of our intervention-level framework (paradigm, goals, system structure, feedback and delays, structural elements) enabled comparison of the conference themes of healthy, green, fair, and affordable. At the level of system structure suggested actions to achieve these goals are fairly compatible, including broad public discussion and implementation of policies and programs that support sustainable food production and distribution. At the level of paradigm and goals, the challenge of making healthy and green food affordable becomes apparent as some actions may be in conflict. Systems thinking can provide insight into the challenges and opportunities to act to make the food supply more healthy, green, fair, and affordable.

Global health research has typically focused on single diseases, and most economic evaluation research to date has analysed technical health interventions to identify ‘best buys’. New approaches in the conduct of economic evaluations are needed to help policymakers in choosing what may be good value (ie, greater health, distribution of health, or financial risk protection) for money (ie, per budget expenditure) investments for health system strengthening (HSS) that tend to be programmatic. We posit that these economic evaluations of HSS interventions will require developing new analytic models of health systems which recognise the dynamic connections between the different components of the health system, characterise the type and interlinks of the system’s delivery platforms; and acknowledge the multiple constraints both within and outside the health sector which limit the system’s capacity to efficiently attain its objectives. We describe priority health system modelling research areas to conduct economic evaluation of HSS interventions and ultimately identify good value for money investments in HSS.

Public policy aimed at reducing obesity is just one of many avenues that must be pursued to address the still-growing obesity pandemic. The complexity of the problem is illustrated in ecological frameworks and system maps of the determinants. These conceptual maps illustrate the complexity by acknowledging the influence of many different factors such as social norms and values; sectors of influence such as the food and beverage industries, media and transportation; behavioural settings including home and family, school and community; and individual factors such as genetics, psychosocial and other personal elements. But to solve such a complex problem, we need to move from an analysis of the determinants or causes of the problem to a solution orientation; the frameworks used to describe the problem may not be the right ones for building the "best" solutions. Solution-oriented frameworks, like those presented by Hobbs and Seeman, have been based on parameters such as the sector of influence (e.g., public policy) but would benefit from the consideration of complexity and the leverage points for intervention in complex systems, which are a function of parameters such as the structure of relationships and the presence or absence of feedback loops.

A dynamic model is built to study the water regulation of human body and related disorders, focusing on the fundamental feedback mechanisms involved in their normal and abnormal physiology. The simulation model is extended to include therapeutic interventions related to the most common body fluid disorder, namely, water intoxication/hyponatremia. The modeling approach is based on system dynamics methodology. Comparisons with experimental and field data show that the model adequately reproduces typical dynamics of the body fluid variables in their normal and diseased states. Finally, an interactive game version is developed to test the possible effects of alternative treatment options on a simulated patient. Simulation and game results reveal the subtleties involved during and after administration of various pharmacological interventions. For example, hypertonic saline should be administered concurrently and in delicate balance with drugs that increase urine flow. The simulator offers a virtual laboratory for experimental research and education on diagnosis and alternative therapies of body water disorders in general and hyponatremia in particular.

Dr. Özge Karanfil is an assistant professor at Koç University jointly at the College of Administrative Sciences and Economics, and its School of Medicine. She received her BSc and MSc degrees in Industrial Engineering from Boğaziçi University, an MSc degree in Physiology from McGill University, and completed her Ph.D. at MIT Sloan School of Management in 2016, with a concentration in health system dynamics. She continued her studies as a Yerby Fellow at Harvard School of Public Health, Department of Global Health and Population between 2016-18 before joining Koç University 2018.
Özge aims to produce policy-relevant research by integrating management, systems, and health sciences with a strong emphasis on data-driven analysis and modeling. Her research areas include system dynamics simulations, dynamic modeling for health policy analysis, physiologically inspired disease modeling, human decision making, and evidence-based medicine. She received the Lupina Young Researchers Award for Healthcare Applications and the Dana Meadows Awards by the System Dynamics Society, the Koç-Harvard Visiting Scholar Fellowship by the Center for Middle Eastern Studies at Harvard University in 2019, and the TÜBİTAK 2232 International Fellowship for Outstanding Researchers with her Project entitled: “Changing Trends in Healthcare Management: Use of Simulation Models to Inform Health Policy and Evidence-Based Decisions” in 2020.
