With the development of health technology assessments, the public are increasingly aware of the importance of assessing timeliness for health decision-making, which emerges the requirement for early and timely assessment for emerging health technologies. Providing early and timely assessments prior to a technology accesses the market or prior to implementation can provide decision-makers with sufficient time to develop an application program for a new technology. This paper mainly summarizes the profiles of three emerging health technology horizon scanning systems in Canada, Australia, New Zealand and Sweden, and compares and analyzes their related contents, thus providing reference experience for the construction of emerging health technology horizon scanning system in China.
