Public Health Approach

Find the patterns, understand what increases danger or helps people stay safe, test a response, and improve it as you learn.

What it means

CDC’s public-health approach starts by finding out what is happening and who is affected. Next, identify conditions that increase danger (risk factors) and conditions that help people stay safe (protective factors). Develop and test responses, then help effective approaches reach more people. Keep checking that the approach fits the community and changes what it is meant to change. Different kinds of firearm harm need different responses.

Here is an example to work through. The linked source explains the idea or guest account. The next move is ICM guidance.

Where it shows up
A team picks a familiar program before agreeing on the harm it is meant to change.
A useful move
Define the outcome and population, examine risks and protective conditions, compare approaches that target those conditions, then review reach and results.
What this does not prove
The four steps are a decision process. They do not prove that a program will work in a new place without delivery and evaluation.
