NYU Department Chair Publishes Case Study on Using System Sciences to Inform Population Health Strategies in Local Health Departments

Dr. José Pagán, the new department chair of public health policy and management at New York University College of Global Public Health (NYU MPH), has had a paper published in the September/October issue of the journal Public Health Reports, titled Systems Science to Inform Population Health Strategies in Local Health Departments: A Case Study in San Antonio, Texas. Due to state and federal health care reform, local health departments play an increasingly prominent role leading and coordinating disease prevention programs in the United States. This case study shows how a local health department working in chronic disease prevention and management can use systems science and evidence-based decision making to inform program selection, implementation, and assessment; enhance engagement with local health systems and organizations; and possibly optimize health care delivery and population health. Some of the results of this case study include:

The authors projected that a one-percentage-point reduction in HbA1c would lead to a decrease in the 20-year prevalence of end-stage renal disease from 1.7% to 0.9%, lower extremity amputation from 4.6% to 2.9%, blindness from 15.1% to 10.7%, myocardial infarction from 23.8% to 17.9%, and stroke from 9.8% to 7.2%. They estimated annual direct medical cost savings (in 2015 US dollars) from reducing HbA1c by one percentage point ranging from $6842 (myocardial infarction) to $39 800 (end-stage renal disease) for each averted case of diabetes complications.

The conclusion of the paper was that local health departments could benefit from the use of systems science and evidence-based decision making to estimate public health program effectiveness and costs, calculate return on investment, and develop a business case for adopting programs.
