This article describes methodological issues, challenges, and a vision for using computer assisted telephone interviewing (CATI) in a comprehensive public health surveillance system in the 21st century. Methodological issues include funding of surveys, survey frequency, sample size considerations, response rates, and types of bias to be considered in questionnaire design. Challenges include the recognition of the merits and limitations of CATI, and the potential for greater use in surveillance of public health issues in health regions requiring rapid and regular data. The vision of a CATI survey-based, rapid, flexible, cost-effective public health surveillance system is described. It is concluded that further discussion and views on improvements with regard to CATI methodological and practical issues will help build a better CATI survey-based public health surveillance system for the future.
本文描述了在21世纪综合公共卫生监测系统中使用计算机辅助电话访谈（CATI）的方法学问题、挑战及愿景。方法学问题包括调查资金、调查频率、样本量考量、回复率以及问卷设计中需考虑的偏差类型。挑战包括认识到CATI的优缺点，以及在需要快速且定期数据的健康区域，其在公共卫生问题监测中更广泛应用的潜力。文中描述了基于CATI调查的、快速、灵活且具成本效益的公共卫生监测系统的愿景。得出的结论是，就CATI方法学和实际问题的改进进行进一步讨论并听取各方意见，将有助于构建一个更完善的、基于CATI调查的未来公共卫生监测系统。
