Background. HCV testing is an important first step for treatment and prevention, particularly for those who are highly vulnerable to HCV infection such as people who inject drugs (PWID). In settings where direct-acting antiretroviral medicines are becoming more available, limited information exists about who and where to target to increase the prevalence of HCV testing among PWID. This study is aimed at understanding the prevalence of HCV testing uptake and its determinants of medical services and risk behaviors. Methods. From February 2016 to April 2017, a sample of 509 PWID was interviewed using a structured questionnaire on their history of HCV testing, confirmation, services using in the previous year as well as HCV-related knowledge, and risk behaviors. Multiple logistic regression identified factors associated with ever being tested for HCV before enrollment in the program. Results. Approximately 33% reported ever testing for HCV. Most cited sources of testing are public hospitals and general clinics (68.9%) and outpatient clinics (18.9%). Having ever tested for HCV was positively associated with accessing health services within the prior 12 months (; 95% CI 1.11-4.58), being currently enrolled in a methadone treatment program (; 95% CI 1.34-4.08), and/or on ART treatment (; 95% CI 1.30-4.08). Those who ever delayed in seeking healthcare services for any reason were less likely to get tested for HCV (; 95% CI 0.35-0.84). Conclusion. HCV testing prevalence is low among PWID in Hanoi despite a very high prevalence of HCV infection. To improve the cascade of HCV testing, it is critical that intervention programs scale up linkages among methadone, outpatient clinics, and HCV services, take steps to reduce stigma and discrimination in both community and, especially, in health care settings, and increase awareness of HCV for PWID by integrating HCV into routine counseling at health care services.

据报道，在越南城市注射毒品的人中，丙肝病毒检测的接受率很低

背景。HCV 检测是治疗和预防的重要第一步，特别是对于那些极易感染 HCV 的人，例如注射吸毒者 (PWID)。在直接作用的抗逆转录病毒药物变得越来越容易获得的环境中，关于在注射吸毒者中增加 HCV 检测流行率的对象和地点的信息有限。本研究旨在了解 HCV 检测的流行率及其对医疗服务和危险行为的决定因素。方法. 2016 年 2 月至 2017 年 4 月，对 509 名 PWID 样本进行了结构化问卷调查，了解他们的 HCV 检测历史、确认情况、上一年使用的服务以及 HCV 相关知识和危险行​​为。多元逻辑回归确定了与参加该计划之前曾经接受过 HCV 检测相关的因素。结果。大约 33% 的人报告曾经检测过 HCV。被引用最多的检测来源是公立医院和综合诊所（68.9%）和门诊（18.9%）。在过去的 12 个月内，曾经检测过 HCV 与获得医疗服务呈正相关（; 95% CI 1.11-4.58），目前正在参加美沙酮治疗计划（; 95% CI 1.34-4.08），和/或接受抗逆转录病毒治疗（; 95% CI 1.30-4.08)。那些因任何原因延迟寻求医疗保健服务的人不太可能接受 HCV 检测（; 95% CI 0.35-0.84)。结论。尽管 HCV 感染率非常高，但河内 PWID 的 HCV 检测率很低。为了改善 HCV 检测的级联，干预计划必须扩大美沙酮、门诊和 HCV 服务之间的联系，采取措施减少社区，特别是医疗保健机构中的污名和歧视，并提高对通过将 HCV 整合到医疗保健服务的常规咨询中来治疗 PWID 的 HCV。
