  1. TallaghtOctober 2010Where Are We Now ? Margaret Bourke GP Coordinator

  2. Partnership • This is the story of what I see as a very successful partnership to provide treatment to a very disadvantaged group in society. Also to bring dignity and caring to the workplace and to provide it to this cohort. Those of you who were here in the early days will remember when treatment was provided in less than ideal venues and we were not provided with a red carpet welcome and serious attempts were made to stop us providing treatment.

  3. Addiction • Is a chronic recidivist illness • The object should be a functioning lifestyle on treatment, with abstinence for those who can achieve it. • It is a disease of neuro chemical pathways. Specific opiate receptors have been identified.

  4. Changing Attitudes “Addictive disorders should be considered in the category with other disorders that require long-term or life long treatment. The treatment of addiction is about as successful as treatment of disorders such as hypertension, diabetes and asthma. It is clearly cost effective…….and as with treatment of these other chronic conditions there is no cure”

  5. Background • The epidemic of heroin in the mid 1980s and the explosion in the 1990s which continues into the 21st century has led to enormous problems with healthcare • Addiction is an illness which needs treatment • There is an increasing need to respond with a statutory duty to provide a multidisciplinary service

  6. Advent of HIV • Led to a demand for stabilization and maintenance treatment programs with methadone. • In response, the then Eastern Health Board set up services.(1992) • What commenced as a HIV prevention programme rapidly became a response to the problem of heroin use. • Increasing evidence of Hepatitis C in injecting drug users fueled the need for treatment.
