The need for health systems modeling

5 08 2010

Just stumbled upon this great article on system dynamics modeling for public health, with this quote about why complex health systems must be examined from system-wide perspective:

“The term dynamic complexity has been used to describe such evolving situations.  Dynamically complex problems are often characterized by long delays between causes and effects, and by multiple goals and interests that may in some ways conflict with one another.  In such situations, it is difficult to know how, where, and when to intervene, because most interventions will have unintended consequences and will tend to be resisted or undermined by opposing interests or as a result of limited resources or capacities.”

Well put.
