Hetzel BS是碘缺乏病概念的提出者，他在2012年撰文《消除缺碘所致脑损伤的全球项目进展》，在文章最后，总结了全球防治碘缺乏病取得明显进展的经验。

1. 《2000年实际消除碘缺乏病》被世界儿童峰会接受为27个目标之一。世界峰会为国家碘消除碘缺乏病项目提供了重要的政治支持。（The Virtual Elimination of Iodine Deficiency Disorders by the year 2000 was included in the 27 goals accepted by the World Summit for Children in 1990.22 The World Summit provided major political support for National IDD Elimination Programmes. ）

2. 世界卫生组织/联合国儿童基金会关于全民/普遍食盐加碘的政策。该政策要求用于人类和动物的所有食物用盐都要加碘。（The WHO/UNICEF policy of Universal Salt Iodization (USI) requires iodization of all food for human and animal consumption by the use of iodized salt (25- 40 mg I/kilo). The salt industry has also accepted and adopted this intervention as a permanent organized measure. ）

3. 全球碘缺乏问题重新定义为碘缺乏病（缩写是IDD），包括了缺碘对人类的所有损伤，不仅仅是甲状腺肿和克汀病，特别是脑损伤，它们都可以通过补碘完全预防。（The global problem of iodine deficiency was redefined by a population concept, with an easy acronym – the concept of the iodine deficiency disorders (IDD) – referring to all gradations of the effects of iodine deficiency in a population, that can be totally prevented by correction of iodine deficiency with special emphasis on brain damage and not just to goitre and cretinism. ）

4. ICCIDD的技术和咨询。得到世界卫生组织、联合国儿童基金会支持的国际控制碘缺乏病理事会（ICCIDD，现称为全球碘营养联盟），由100多个国家的700余名多学科专家组成，他们对国家消除IDD提供了技术帮助，关对科学问题提供了国际水平的咨询。（The International Council for Control of Iodine Deficiency Disorders (ICCIDD) supported by WHO and UNICEF with 700 multidisciplinary professionals from more than 100 countries, has provided technical assistance to national programs for the elimination of IDD as well as advice at global level on scientific issues. ）

5有效地大规模使用的简单而实用的监测技术，即得到ICCIDD技术支持的盐碘和尿碘检测方法。（Simple practical methods for monitoring –the measurement of salt iodine and urine iodine have been made effective for use on a large scale with the technical assistance of the ICCIDD. ）
