尽管症状监测越来越受欢迎，但对这些系统是否或如何被最终用户接受、利用和重视却知之甚少。本研究旨在描述症状监测系统在安大略的使用和用户对这些系统在其他监测系统中的价值的看法。安大略省36个公共卫生单位，省卫生部和联邦公共卫生署完成了一项网络调查，以确定常规使用和大流行病期间使用的传统和综合征监测系统，并说明系统的属性和监测效用20/38（53）个组织使用了症状监测系统。对于常规监测，实验室、综合公共卫生信息系统和学校缺勤数据是最常用的来源。实验室数据在可靠性、及时性和准确性方面获得了最高评级（92、51和89）。医院/诊所筛选数据被评为最可靠和最及时的综合征数据来源（50和43），艾德访视数据最准确（48）。在大流行期间，实验室数据被认为是监测流行病学和为决策提供信息最有用的数据，而艾德筛查和就诊数据被认为是最有用的症状来源。
Despite the growing popularity of syndromic surveillance, little is known about if or how these systems are accepted, utilized and valued by end users. This study seeks to describe the use of syndromic surveillance systems in Ontario and users perceptions of the value of these systems within the context of other surveillance systems.Ontarios 36 public health units, the provincial ministry of health and federal public health agency completed a web survey to identify traditional and syndromic surveillance systems used routinely and during the pandemic and to describe system attributes and utility in monitoring pandemic activity and informing decision-making.Syndromic surveillance systems are used by 20/38 (53) organizations. For routine surveillance, laboratory, integrated Public Health Information System and school absenteeism data are the most frequently used sources. Laboratory data received the highest ratings for reliability, timeliness and accuracy (overy acceptable' by 92, 51 and 89). Hospital/clinic screening data were rated as the most reliable and timely syndromic data source (50 and 43) and ED visit data the most accurate (48). During the pandemic, laboratory data were considered the most useful for monitoring the epidemiology and informing decision-making while ED screening and visit data were considered the most useful syndromic sources.End user perceptions are valuable for identifying opportunities for improvement and guiding further investments in public health surveillance.
