Public Health and the origins of the Mersey Model of Harm Reduction.

In the mid-1980s in Liverpool, and the area surrounding it (Merseyside and Cheshire), harm reduction was adopted on a large scale for the first time in the UK. The harm reduction model was based on a population approach to achieve the public health goal of reducing the harm to health associated with drug use. The particular concern at that time was the risk of HIV infection, but there was also the issue of the health of a group of young people who were under-served by health services. To achieve the goal, services were developed that would attract the majority of those at risk within the community, not simply the few who wished to stop using drugs, and which would enable contact with the target group to be maintained so as to bring about the necessary changes in behaviour required to maintain health and reduce risk. This Commentary describes some of the background to the development of the Mersey Model of Harm Reduction from the memories and perspectives of two people who promoted harm reduction within the health service and the region.
