[...]the value of and need for PHSSR is juxtaposed against the ever-present and well-known challenges in undertaking research of this ilk: the complexities of defining the public health system, the lack of quality and complete data, the limited resources and sustainable funding for research, and the need for innovative and appropriate methods to analyze complex and adaptive system concepts. [...]stronger engagement and a more cohesive sense of the system should cultivate greater inclusion of public health practitioners.
