Question 3 (short answer within 300 words)
The Haddon Matrix is one useful tool for analysing events that result in injury, so that we can develop strategies to reduce injury risk. Use the Haddon Matrix (see Chapter 22 of Frumkin (2010)) to analyse risk for the following scenario:
A twenty-year old female driver had attended a family celebration and consumed alcoholic beverages throughout the course of the evening. She departed for home before midnight, forgetting to fasten her seatbelt for the drive home. The road was dry and unlit. The driver, driving an older model compact vehicle, braked before a curve in the road, but her brake pads were worn and did not slow the car sufficiently to round the curve. She swerved and the car rolled over several times. The car did not have airbags. She was discovered shortly after and transported to hospital, but remained in a coma

Answer 1

Haddon matrix is a tool to assist in developing ideas for preventing injuries of many types . It is a useful brainstorming tool to help identify different ways of intervening to address injury risks.

It is essentially a three by three table that helps people brainstorm ideas for designing interventions to address injuries from multiple dimensions.

The 3 headings of the Haddon Matrix horizontally at the top are :-

Host/human, Vehicle/agent, Environment

The 3 side-headings of the Haddon Matrix vertically on the left are :-

Pre-event, Event/Crash site, Post-event

Human Vector Physical environment Socio-economi (or host) environment Pre- Is host pre-disposed or overexposed to risk? Is vector hazardous? Is environment hazardous? Does environment event discour encourage or risk-taking and hazard Does it have hazard-reduction features? Is host able to tolerate Does vector Event Does environment Does environment force or energy transfer? provide protection? contribute to injury during event? contribute to injury during event? Post How severe is the trauma or harm? Does vector Does environment Does environment contribute to the add to the trauma contribute to event trauma? after the event? recovery

# In this scenario , there are many risk factors for the driver and these are :-

- the driver has consumed alcoholics

- the car was an older model compact vehicle

- the driver has not fasten the seat belts

- the car does not had airbags

- the cars brake pads worn out

- the road was dry and unlit
