5 National HIV Drug Resistance Working Group
Established in July,2004 The committee members include Epidemiologists Clinicians Laboratory scientists Data statisticians Help core labs to prepare protocols for HIV DR surveillance and monitoring, including field epidemiology and laboratory protocols Meet regularly to make plans for HIV DR and to review progresses and new data

6 全国HIV抗病毒治疗耐药性监测工作组 于2004年7月成立 成员包括下列领域的专家: 流行病学 临床医学 病毒学 数理统计学

7 Plan for the National HIVDR Network
Stage One( )the Initiation Phase A pilot study,a report to MOH Sponsored by China MOH, the network was established. 4 labs was nominated as core labs. Training to provincial staff Stage Two( )the Developmental Phase Conducting nationwide HIVDR surveys; Training to provincial laboratories; Participating in a WHO recognized QA program for genotyping Establishing 10 provincial labs as HIVDR genotypic test laboratory Stage Three( ) Consolidation phase Core labs became National HIVDR labs (NDRL) credited by the WHO ResNet. Core Labs provide stronger technical support and quality control to the HIVDR network To establish another 10 provincial labs as HIVDR genotypic test laboratory

8 全国HIV耐药网络的总体发展 第一阶段(2003-2004年)——启动阶段 HIV耐药监测试点工作和对重点HARRT治疗省提供技术培训
第二阶段( 年)——发展阶段 由核心实验室开展全国免费抗病毒治疗的抽样调查 核心实验室参与WHOHIV耐药毒株监测网质评 核心实验室对省级实验室进行培训支持省实验室开展监测工作 将HIV耐药毒株监测网进一步扩大到10个省吸实验室 第三阶段( 年)——巩固阶段 3个核心实验室成为WHO耐药网络实验室, 作为全球耐药监测网 的一部分 核心实验室成为省实验室提供培训技术支持和质量控制 将HIV耐药毒株监测网进一步扩大到20个省实验室 上述为以公共卫生为目的的耐药监测 全国医疗机构的以个体化病人服务的耐药监测可独立发展 全国HIVDR网可为其提供技术和质量管理的支持。
