Rates of absenteeism (missed work), presenteeism (impairment while working) and overall loss of productivity were 15.8%, 5.6% and 11.2%, respectively, as measured by the WPAI-GH questionnaire. The most proficient job was \u2018freelancer\u2019 (17.5%), followed by \u2018blue-collar worker\u2019 (10.6%) and \u2018farmer\u2019 (10.2%). Only 26.8% of patients reported that they actively sought jobs in the past. About half of them had been refused by employers because of their drug use history and\/or HIV status. We found no statistically significant difference between patients enrolled in MMT for &lt;1\u2009year and those who had been enrolled &gt;1\u2009year. Factors associated with higher work productivity included not endorsing problems in mobility, self-care or pain; being HIV-negative and having greater MMT treatment adherence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our study highlights the high employment rate and work productivity among PWID in MMT programmes in remote areas of Northern Vietnam.
