On a primary prevention level, we can vaccinate for HBV, discuss harm reduction and lifestyle modification. On a secondary prevention level, we can provide timely diagnoses and cure hepatitis C, monitor hepatitis B and treat if eligible, address other comorbidities to reduce harm such as alcohol, smoking and obesity. On a tertiary prevention level, we have a role in HCC surveillance and providing early diagnosis and treatment of HCC.
The majority of viral hepatitis diagnoses are made in primary care but unlike tackling HIV where high case-load clinics exist, viral hepatitis is not concentrated in a few clinics (prisons are the exception). Hence we need to cast a wider net through opportunistic assessment. Nicole Allard has made an important observation, that there is little mention of HCV screening activities in the RACGP Red Book and has suggested that this could reasonably be done in the setting of other preventive health activities. There is a service gap in terms of coverage of the response to HCV in primary care, currently 1% of GPs are prescribers and 10% of antiviral scripts were by GPs. Not only do we need to continue to ramp up testing for HCV but we also need to look at streamlining treatment and monitoring.
Other strategies such as incorporating lab reflex HCV RNA testing has been topically discussed during AVHEC19, as was the incredible effort by New Zealand in building widespread awareness through mass media campaigns to make patients into the best advocates. This session also sparked active discussion from the audience around the follow up of notifications to improve the cascade for people already diagnosed and how this data could be better shared among healthcare collaborators to improve HCC surveillance.
So it appears that having widely available and effective DAA’s is just the tip of the iceberg. There are still exciting times ahead and time to get more primary care providers involved across all levels of HCV preventive health activities.
