Public health work has changed significantly since its formalization in the 19th Century, and even today it is poised for further transformation

It matters how we think about the trends, dilemmas, and innovations that we experience, and it matters whether our thinking and actions match

We are not talking about theories to explain, but conceptual, methodological, and moral orientations: the frames of reference that shape how we think, how we act, and what we value

“Public death was first recognized as a matter of civilized concern

in the nineteenth century, when some public health workers

decided that untimely death was a question between men and

society, not between men and God….Since then, and for that

reason, millions of lives have been saved….The pioneers of public

health did not change nature, or men, but adjusted the active

relationship of men to certain aspects of nature so that the

relationship became one of watchful and healthy respect.

Syn·demic Syn·demic

The term syndemic, first used in 1992, strips away the idea that illnesses originate from extraordinary or supernatural forces and places the responsibility for affliction squarely within the public arena

It acknowledges relationships and signals a commitment to studying health as a a fragile, dynamic state requiring continual effort to maintain and one that is imperiled when social and physical forces operate in harmful ways

health-related problems, considers those connections when developing

health policies, and aligns with other avenues of social change to assure the

conditions in which all people can be healthy

Complements single-issue prevention strategies, which can be effective for discrete problems but often are mismatched to the goal of assuring conditions for health in its widest sense

Incorporates 21st century systems science and political sensibilities, but the underlying concepts are not new. Still, the implications of adhering to this orientation remain largely unexplored.

Assumption that healthcare dynamics are separate from other areas of public concern

Conventional analytic methods make it difficult to

Observe the health system as a large, dynamic enterprise

Craft high-leverage strategies that can overcome policy resistance

Been thinking of health and healthcare as nouns (i.e., commodities to be distributed), not as verbs (i.e., public work to be produced)

“Simulation is a third way of doing science. Like deduction, it

starts with a set of explicit assumptions. But unlike deduction,

it does not prove theorems. Instead, a simulation generates

data that can be analyzed inductively. Unlike typical induction,

however, the simulated data comes from a rigorously specified

set of rules rather than direct measurement of the real world.

While induction can be used to find patterns in data, and

deduction can be used to find consequences of assumptions,

simulation modeling can be used as an aid to intuition.”

tunnel vision is that it brings into sharp focus

certain limited aspects of an otherwise far more

complex and unwieldy reality. This very

simplification, in turn, makes the phenomenon at

the center of the field of vision more legible and

hence more susceptible to careful measurement

and calculation….making possible a high degree of

The word syndemic signals special concern for many kinds of relationships:

mutually reinforcing health problems

health status and living conditions

synergy/fragmentation in the health response system

Phase 1 (2001-2003): identify innovations and dilemmas; develop working definitions; explore relevant concepts and methods

Phase 2 (2004-2005): articulate the foundations of a syndemic orientation; work with leaders at the CDC and beyond to stimulate creativity, innovation, and reorient health protection ventures

"In problem solving we seek to make something we do not like

go away. In creating, we seek to make what we truly care

about exist… We can get so caught up in reacting to problems

that it is easy to forget what we actually want. Organizations

must do both–resolve day-to-day problems and generate new

results. But if your primary role is to fix problems, individually

or collectively, rather than create something new and

meaningful, it's hard to maintain a sense of purpose, and..it's

difficult to harness the energy, passion, commitment, and

perseverance needed to thrive in challenging times."

“Even the best conceptual models can only be tested and improved by relying on the learning feedback through the real world…This feedback is very slow and often rendered ineffective by dynamic complexity, time delays, inadequate and ambiguous feedback, poor reasoning skills, defensive reactions, and the costs of experimentation. In these circumstances simulation becomes the only reliable way to test a hypothesis and evaluate the likely effects of policies."
