简介:目的对2HRZE/4H3R3和2H3R3Z3E3/4H3R3治疗初治涂阳肺结核病患者社会效果评价,为结核病的社会控制提供依据。方法应用中国卫生部结核病控制项目2HRZE/4H3R3方案,治疗初治涂阳肺结核病人的监测资料和2003年对《中国结核病控制规划(2001—2010)))阶段评估,抽查“世界银行贷款+中国结核病控制项目”2H3R3Z3E3/4H3R3方案治疗初治涂阳肺结核病人治疗的资料进行分析。结果在落实较好的全程督导服药治疗下,两方案已达到国家规划目标。目前2H3R3Z3E3/4H3R3未能达到国家规划目标,治愈率明显较强化期每日服药方案低,而失败率、丢失率、副反应停药率明显较高。结论经费落实不到位导致患者全程督导服药治疗不能很好落实,是影响化疗效果的主要原因。由于全程督导服药治疗不能很好落实,致使全程隔日服药方案不能胜任规划目标的要求,提示结核病控制的方向。
