Q

What is harm reduction?

A

Harm reduction is a collection of strategies that are aimed at reducing the negative consequences of an act. It focuses on the behaviour, not the person.

24
Q

What are the six guiding principles of harm reduction?

A
  • First, do no harm
  • Focus on the harms caused by the activity, rather than the activity itself
  • Maximize intervention options
  • Choose appropriate outcome goals, giving priority to effective programs with practical, realizable goals
  • Give priority to new and innovative programming
  • Respect the rights of the person you are treating
25
Q

What are the main components of harm reduction?

A
  • Address and accept the client where he or she is
  • Focus on reducing the harm caused by the substance use, not on the use of substance, but may be included
  • Client is able to select goals that range from abstinence to safer use
  • Treatment is based on the rights of the individuals to make choices
  • Health care professionals need to be skilled in therapeutic approaches and the biopsychosocial determinants of addictions
  • Based on the ‘do no harm’ concept of medical practice
  • Priority of goals depends on the immediate needs of the client
  • Methods are based on research in self-efficacy and change
  • Clients do not need to be substance free to be in treatment
  • Harm reduction is neutral with respect to abstinence; all depends on the goals of the client
  • No moral judgments are made regarding the substance use: the benefits of substance use are taken into consideration as a means to understand the use of these substances
  • Treatment can be combined with existing treatment strategies and may be most effective in this matter
26
Q

Opioid substitution therapy

A

Methadone
- Oral, and liquid form (can be supervised easily)
- Lasts 24 hours, (eliminates peaks)
- Side effects decrease (tolerance)
- Therapeutic dose: withdrawal syndrome management
- Protects against overdose

Suboxone
1) BUPRENORPHINE (BUP)
- Partial mu agonist with ceiling effect
- Very high affinity for opiate receptors so can “bump” other opiates off the receptors
2) NALOXONE (NARCAN)
- mu antagonist with no effect when taken sublingually
- Added to discourage injection
