In the Netherlands a program is being implemented to offer annual voluntary screening for these infections to opioid drug users ODUs screened in methadone care. At two care sites where the program is now operating our study aimed to estimate the seroprevalence among ODUs screened for HIV HBV and HCV to evaluate HBV vaccination coverage and to assess the feasibility of monitoring seroprevalence trends by using routine annual screening data. Methods Opioid drug users on methadone treatment are routinely offered voluntary screening for infectious diseases such as HIV HBV and HCV. Data on uptake and outcome of anti-HIV anti-HBc and anti-HCV screening among ODUs receiving methadone were obtained from two regions Amsterdam from 2004 to 2008 and Heerlen from 2003 to 2009. Findings Annual screening uptake for HIV HBV and HCV varied from 34 to 69 depending on disease and screening site. Of users screened were HIV-positive in Amsterdam and 11 in Heerlen 26 were HCV-positive in Amsterdam and 61 in Heerlen. Of those screened for HBV evidence of current or previous infection anti-HBc was found among 33 in Amsterdam and 48 in Heerlen. In Amsterdam 92 were fully vaccinated for HBV versus 45 in Heerlen. Conclusion Annual screening for infectious diseases in all ODUs in
