Models of care teams
• Hospital model
– The most common
– Usually offered by specialists
• Model frontline proximity
– Provides care in the home environment
– Very low treshold
• Model frontline family medicine
– Additional services for patients in substitution treatment
– Interdisciplinary team in one place
• Health care in prisons

Collaboration
• Since 2001, CRD Le Virage and GMF de l’UMF Charles
LeMoyne have worked together to offer services for
the treatment of opiate addiction
– Nurses and social wokers from the CRD Le Virage
support the medical team in the care offered
– The Virage staff involved in the substition
treatment program work on the premises of the
medical clinic. On a daily basis we are the
frontline in answering to the various needs of the
patients in the program

HCV Treatment at GMF de l’UMF
Charles LeMoyne: some background
• About a third of patients followed in substitution
treatment are infected with HCV
• Very little success with the traditional organization in
hospital
– Mutual reluctance patients/specialists
– Many stops along the treatment
• Practice guidelines that do not promote treatment in
IDU
HCV Treatment at GMF de l’UMF
Charles LeMoyne: some background
• Patients under replacement therapy→time
and place ideal for treating hepatitis C?
– Often more stable period
– Existing regular medical follow-up
– Trust already established with the team
• Experience of treating some patients but not
in an organized manner (No involvment of
Virage staff but use of nursing resources made
available by pharmaceutical industry)
HCV Treatment at GMF de l’UMF
Charles LeMoyne: Research Project
• Based on the OASIS model
San francisco Organization to Achieve Solutions in Subtance-Abuse




HCV Treatment on site
By professionals from the clinic
Inclusion if replacement therapy for 3 months
No systematic exclusion if active drug users
HCV Treatment in GMF de l’UMF
Charles LeMoyne: Research Project
• Quebec: no example like OASIS model
• Structure at UMF is in favor of this type of support
• Interest of professionals
• Little evidence: research project sponsored by
Hoffman-Laroche
