The Problem
• 90% chronic Hepatitis B infection with vertical
transmission
• Chronic Hepatitis B causes cirrhosis and
hepatocellular carcinoma
• In SE Asia and China in particular,
approximately 10% of population has chronic
Hepatitis B
• Immigration to areas of low endemicity can
lead to personal and public health difficulties

The Problem
• Knowledge of Hepatitis B is poor in SE Asian
immigrant populations
• Stigma attached to having Hepatitis B
• Less than half of those eligible will request
screening
• Different health beliefs and cultures

easy-to-reach members of the Community
and through them communicate with
members who are harder to reach

Serology by Age
![Page 18: Screening the Chinese Community for Hepatitis B · Screening the Chinese Community for Hepatitis B Hazel Younger Consultant Gastroenterologist Raigmore Hospital, Inverness.

Problems
• GP sub-committee not consulted
• ‘Unaware’ of project
• Testing and referral, vaccination of contacts
through primary care
• Vaccination provided as ‘travel’ service –
considerable cost to individuals
![Page 19: Screening the Chinese Community for Hepatitis B · Screening the Chinese Community for Hepatitis B Hazel Younger Consultant Gastroenterologist Raigmore Hospital, Inverness. The Problem](https://reader031.vdocuments.us/reader031/viewer/2022041401/5e1756e12fec236d490ffc44/html5/thumbnails/19.jpg)
‘Resolution’ of Problems
• Offered serology testing at RIE if GP unable
• Negotiations with Bloodbourne Virus
Committee re payment for vaccination of
household contacts (£7/vaccination)

Evaluation of Project
• Overall well-received by Chinese community
• Group-based meetings better attended than general public (advertised)
• Diffusion model appeared to work
• Chinese Hepatitis B clinic established at RIE (58 patients at conclusion of project)
• < 1% DNA rate!
• Printed bilingual leaflet for general use
• Difficulty with local (primary care) politics

National Screening for Hepatitis B
• ‘Screening for Hepatitis B and Hepatitis C
among ethnic minorities born outside the UK’
• August 2010, report for the National
Screening Committee
• Did not support screening
![Page 22: Screening the Chinese Community for Hepatitis B · Screening the Chinese Community for Hepatitis B Hazel Younger Consultant Gastroenterologist Raigmore Hospital, Inverness. The Problem](https://reader031.vdocuments.us/reader031/viewer/2022041401/5e1756e12fec236d490ffc44/html5/thumbnails/22.jpg)
Chronic Hepatitis B Case-finding
• Systematic case-finding in high risk
populations (health services identify and
invite for test)
• Opportunistic (testing offered to high risk
individuals when make contact with health
services for another reason)
• Voluntary testing (eg at community venues)
![Page 23: Screening the Chinese Community for Hepatitis B · Screening the Chinese Community for Hepatitis B Hazel Younger Consultant Gastroenterologist Raigmore Hospital, Inverness. The Problem](https://reader031.vdocuments.us/reader031/viewer/2022041401/5e1756e12fec236d490ffc44/html5/thumbnails/23.jpg)
Systematic Screening – Research Required
• Systems for identifying high risk patients from
GP records and confirming country of birth
• ? Difference in acceptability and number of
cases found between systematic and
opportunistic testing
• What will uptake be for patients offered
systematic screening?
![Page 24: Screening the Chinese Community for Hepatitis B · Screening the Chinese Community for Hepatitis B Hazel Younger Consultant Gastroenterologist Raigmore Hospital, Inverness. The Problem](https://reader031.vdocuments.us/reader031/viewer/2022041401/5e1756e12fec236d490ffc44/html5/thumbnails/24.jpg)
Systematic Screening – Research Required
• Incremental cost-effectiveness of systemic
over opportunistic testing
– Proportion of HBV actually treated
– Emigration of immigrants after testing and
treatment
– Effect of broadening criteria to country of origin
rather than birth
• No of cases HBV prevented by vaccination

Personal Thoughts
• Involvement of target community in
organisation of project
• Involvement of primary care as well as public
health
• Very little evidence but probably supports
opportunistic case finding and voluntary
testing sessions
• Methodical screening should be set up as a
formal pilot study

Personal Thoughts
• Think through whole process, from contact
with population to vaccination or treatment
• Use interpreters
• Lunchtime meetings!
