This study characterized the evolution of Brazilian public telemedicine policy in the Brazilian Unified Health System for 30 years from 1988 to 2019 by analyzing its legal framework. We identified 79 telemedicine-related legislations from the federal government (laws, decrees, and ordinances) and 31 regulations of federal councils of health professionals. Three historical phases were established according to the public policy cycle, and material was classified according to the purpose of the normative documents. The content analysis was based on the advocacy coalition framework model. Of the federal legislations, 8.9% were for the Formulation/Decision-Making phase, 43% for the Organization/Implementation phase, and 48.1% for the Expansion/Maturation phase of telemedicine policy in Brazil. The Federal Council of Medicine was the most active in standardizing telemedicine and was responsible for 21 (67.7%) regulations. The first legislations were passed in 2000; however, the coalitions discussed topics related to telemedicine and created their belief systems from the 1990’s. The time cycle which included formulation and decision making for Brazilian telemedicine policy, extended until 2007 with the creation of several technical working groups. The expansion and maturation of telemedicine services began in 2011 with the decentralization of telemedicine policy actions across the country. Telemedicine centers which performed telediagnosis influenced the computerization of primary health care units. We conclude that Brazilian telemedicine field has greatly grown and changed in recent years. However, despite the proliferation of legislations and regulations in the period studied, there is still no fully consolidated process for setting up a wholly defined regulatory framework for telemedicine in Brazil.

通过分析巴西统一医疗系统的法律框架，该研究描述了从1988年至2019年30年间巴西统一远程医疗政策在巴西统一医疗系统中的发展情况。我们从联邦政府中确定了79项与远程医疗相关的法规（法律，法令和条例）和联邦卫生专业人员委员会的31条法规。根据公共政策周期确定了三个历史阶段，并根据规范性文件的目的对材料进行了分类。内容分析基于倡导联盟框架模型。在联邦立法中，巴西有8.9％用于制定/决策阶段，43％用于组织/实施阶段，48.1％用于远程医疗政策的扩展/成熟阶段。联邦医学委员会在标准化远程医疗方面最为活跃，并负责21项（67.7％）法规。最早的立法于2000年通过。但是，联盟讨论了与远程医疗有关的主题，并从1990年代创建了他们的信仰体系。包括制定和决策巴西远程医疗政策的时间周期一直延伸到2007年，并成立了多个技术工作组。随着全国范围内远程医疗政策行动的下放，远程医疗服务的扩展和成熟始于2011年。进行远程诊断的远程医疗中心影响了初级保健单位的计算机化。我们得出的结论是，近年来，巴西的远程医疗领域有了很大的发展和变化。然而，
