Haddon Matrix

The Haddon Matrix is the most commonly used paradigm in the injury prevention field.

Developed by William Haddon in 1970, the matrix looks at factors related to personal attributes, vector or agent attributes, and environmental attributes before, during and after an injury or death. By utilizing this framework, one can then think about evaluating the relative importance of different factors and design interventions.

Famous quotes containing the word matrix:

    As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the matrix out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.
    Margaret Atwood (b. 1939)
