Knowledge (Survey # 4)
Treatment naive, people who inject drugs (treatment focus):
Overall, knowledge poor (but risk over estimated)– 42% correct re chance of liver damage– 15% correct re chance of liver cancer
Higher knowledge scores were associated with:– recruitment site (HCCNSW > dispensing pharmacies, OST)– higher education levels– recent contact with a general practitioner for any reason

Alcohol
What are messages that people receive?:
“I’ve never even had a doctor tell me I shouldn’t be drinking with hep [hepatitis] C. Most of my friends drink copious amounts, who’ve got it. And they don’t appear to have ever been advised otherwise.”
“Whenever I mentioned drinking to doctors, they just kind of looked the other way. . . . They just didn’t think it was a problem. It was like, ‘What are you worried about?’”

Alcohol
Voice of medicine is paramount; lifeworlds excluded
Meanings of alcohol explored; social barriers to change acknowledged -> more effective models of alcohol-related care and support

Clinical Markers - ALT
No because I know they’re very unreliable, the ALT levels. I don’t think it’s anything you can really take too seriously ... But I know that, yeah a friend of mine that doesn’t look after herself at all and is on a methadone programme, doesn’t eat any food, she’ll go and have a blood test and even when she’s using and taking methadone, she’ll have a blood test and come out with a 120 …and the doctors indicated to me that it’s not a really reliable gauge of your condition.

Diagnosis experiences
Key moment in care and management– Study of 24 recent seroconverters (within 2 years)– 9/24 – antibody and LFT tests only
Majority – experience did not meet some or any of components of national policy

Re self management:
‘Oh the doctor didn’t say anything just that, except that I have hep C. And they didn’t explain to me anything about it or anything really. I didn’t get given anything. I asked, “Do I need to change my diet or anything?” and I was told, “No, nothing I could do.”’

Evolving Models**
Models of care (ongoing and some proposed)- Community Clinic - NZ
- ETHOS – hepatitis C in opiate substitution settings, incl peer support
- GP Initiation – specific genotyopes, ? For bocepravir/telaprovir
- Care for Aboriginal people- central notion of shame- living well with the virus (rather than treatment) - group treatment (McNally & Latham, 2009)
![Page 23: Overview of relevant research for self management in hepatitis C Carla Treloar](https://reader035.vdocuments.site/reader035/viewer/2022062715/56649d935503460f94a79a01/html5/thumbnails/23.jpg)

Summary
Clinical/funding/policy emphasis on treatment
Lack of data on self-reported health (though it is nt’l strategy indicator)
Often poor diagnosis experience
Clinical markers not useful/relevant for self management
Knowledge typically poor in usual care systems- eg alcohol complex and socially embedded- ongoing engagement can produce remarkable results
Responsibilising – possibility for blame/failure (Fraser, 2004)
![Page 25: Overview of relevant research for self management in hepatitis C Carla Treloar](https://reader035.vdocuments.site/reader035/viewer/2022062715/56649d935503460f94a79a01/html5/thumbnails/25.jpg)
Self management & harm reduction
Critique of self-management using harm reduction principles:those most likely to attend self-management interventions are
well-resourced in terms of financesvoice of the person is remarkably absent in researchdetermination of the intervention by HCW
– presupposes that HCW knows best what is good/right for person– interfering with the authoritative knowledge that the ill person
has developed over time about what works best for him or her and under what circumstances
involved as partners in decisions about the design, implementation and evaluation of self-management interventions
Paterson & Hopwood (2010)
![Page 26: Overview of relevant research for self management in hepatitis C Carla Treloar](https://reader035.vdocuments.site/reader035/viewer/2022062715/56649d935503460f94a79a01/html5/thumbnails/26.jpg)
Self management & harm reduction
Compassionate pragmatism of harm reduction:self-management requires foregrounding illnessan intervention that is framed as assisting the person to
comply with a prescribed regime is seen as requiring submission to authority
nature and quality of the person’s relationship with the HCW or peer who is providing the intervention – but little research about this
accepting a person’s goals for living with a disease as a legitimate starting point rather than singular view: avoids comply or rebel bind
Paterson & Hopwood (2010)
![Page 27: Overview of relevant research for self management in hepatitis C Carla Treloar](https://reader035.vdocuments.site/reader035/viewer/2022062715/56649d935503460f94a79a01/html5/thumbnails/27.jpg)
Self management & harm reduction
Healthism:solutions to preventing or managing illness are seen to lie in the
realm of individual choicedenies the social and cultural constraints that people with chronic
illness experience against ‘choosing’blame individual, undermines social efforts to improve health/well
being
Harm reduction theory:attempt to recognize and remove personal judgments about
individual behaviour and instead focus on ameliorating the negative consequences of unhealthy practice
What is considered as best-practice? Who will resist/acknowledge HR principles?
Paterson & Hopwood (2010)

Conclusions
Working with low knowledge
GPs not optimal partners in self-management at this point- Need ongoing engagement- Community partners very important, and already doing this- Telephone, online, existing networks
Self-management not a “sexy” outcome
Recognise that resources are required to support self-management (this is not “no cost”) & need for collaboratively defined goals
