Summary
Injecting drug users in methadone programs show high rates of hepatitis C (78.8%) and HIV (16.7%). Improved screening and hepatitis B vaccination records are crucial for this high-risk population.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Injecting drug users (IDUs) face significant risks of blood-borne infections.
- Ireland has implemented harm reduction strategies, including methadone maintenance and needle exchange programs, since 1992.
Purpose of the Study:
- To determine the prevalence of hepatitis B, hepatitis C, and HIV infections among individuals attending methadone programs.
- To assess the uptake of hepatitis B vaccination in this population.
- To propose recommendations for a simplified record-based surveillance system.
Main Methods:
- A retrospective study analyzed 138 client records.
- The review focused on evidence of laboratory testing for blood-borne viruses.
- Assessment included documentation of hepatitis B immunisation status.
Main Results:
- 60% of clients had records of at least one laboratory test.
- Among tested individuals, 5.1% were positive for hepatitis B surface antigen.
- Prevalence rates were 78.8% for hepatitis C antibodies and 16.7% for HIV.
- Nearly two-thirds of clients lacked vaccination records or evidence of prior immunity.
Conclusions:
- A standardized protocol for blood-borne virus screening and hepatitis B immunisation is essential for methadone service attendees.
- The Eastern Region Health Authority subsequently implemented such a protocol.
