Objective:
Patients prescribed methadone maintenance treatment (MMT) demonstrate elevated prevalence of hepatitis B virus (HBV), hepatitis C virus, and HIV. Government agencies recommend testing for these infections in MMT programs, but uptake is limited.
Methods:
We audited infection-related policies and practices of all 14 MMT programs in Philadelphia, Pennsylvania, in 2015. Results were tabulated and compared with the results from a 2010 audit of 10 of 12 MMT programs. The audit focused on which patients are tested, timing and frequency, specific tests ordered, vaccination, and communication of test results.
Results:
Written policies were nonspecific, offering little guidance on appropriate testing. The principal change in policy between 2010 and 2015 involved adding clearer guidance for communication of results to patients. In 2010 and 2015, all MMT programs tested new patients for hepatitis C virus antibodies, although retesting of existing patients varied. HBV testing increased from 2010 to 2015, though it was not uniform, with 5 programs testing for HBV surface antibodies and 10 programs testing for HBV surface antigens. Six programs assessed hepatitis vaccination status, but only 1 administered vaccines. In 2010, city-sponsored HIV antibody testing was available at all MMT programs. Without this program in 2015, few MMT programs conducted HIV testing.
Conclusions:
Despite limited hepatitis and HIV screening in MMT programs nationally, this study shows that testing can be incorporated into routine procedures. MMT programs are positioned to play an integral role in the identification of patients with chronic infections, but additional guidance and resources are required to maximize their impact.
Insights
Methadone maintenance treatment (MMT) programs show limited hepatitis B, C, and HIV testing despite high infection rates. Audits revealed inconsistent practices, highlighting the need for better guidance and resources to improve screening in MMT settings.
Area of Science:
- Infectious Disease Epidemiology
- Public Health Policy
Background:
- Patients in methadone maintenance treatment (MMT) have a higher prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV.
- Despite recommendations, screening for these infections within MMT programs is not consistently implemented.
Purpose of the Study:
- To audit and compare infection-related policies and practices in Philadelphia MMT programs between 2010 and 2015.
- To assess the uptake and consistency of HBV, HCV, and HIV testing and hepatitis vaccination in MMT programs.
Main Methods:
- A comparative audit of infection-related policies and practices was conducted in 14 MMT programs in Philadelphia in 2015, with data compared to a 2010 audit.
- The audit focused on patient testing, timing, frequency, specific tests, vaccination status, and results communication.
Main Results:
- Written policies lacked specific guidance for testing. Hepatitis C virus antibody testing was universal for new patients, but retesting varied. Hepatitis B virus testing increased but remained inconsistent.
- Hepatitis vaccination assessment was low, with minimal administration. HIV testing declined significantly in 2015 due to the discontinuation of a city-sponsored program.
Conclusions:
- MMT programs are crucial for identifying chronic infections but require enhanced guidance and resources to improve screening.
- Integrating hepatitis and HIV screening into routine MMT procedures is feasible and necessary to address high infection prevalence.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
