There is increasing interest in the use of administrative data for surveillance and research in Australia. The purpose of the present study was to evaluate the usefulness of such data for the surveillance of mood and anxiety disorder using databases from the following Canadian provinces: British Columbia, Ontario, Quebec and Nova Scotia.
A population-based record-linkage analysis was done using data from physician billings and hospital discharge abstracts, and community-based clinics using a case definition of ICD-9 diagnoses of 296.0-296.9, 311.0, and 300.0-300.9.
The prevalence of treated mood and/or anxiety disorder was similar in Nova Scotia, British Columbia, and Ontario at approximately 10%. The prevalence for Quebec was slightly lower at 8%. Findings from the provinces showed consistency across age and sex despite variations in data coding. Women tended to show a higher prevalence overall of mood and anxiety disorder than men. There was considerably more variation, however, when treated anxiety (300.0-300.9) and mood disorders (296.0-296.9, 311.0) were considered separately. Prevalence increased steadily to middle age, declining in the 50s and 60s, and then increased after 70 years of age.
Administrative data can provide a useful, reliable and economical source of information for the surveillance of treated mood and/or anxiety disorder. Due to the lack of specificity, however, in the diagnoses and data capture, it may be difficult to conduct surveillance of mood and anxiety disorders as separate entities. These findings may have implications for the surveillance of mood and anxiety disorders in Australia with the development of a national network for the extraction, linkage and analysis of administrative data.
在澳大利亚，人们对利用行政数据进行监测和研究的兴趣日益浓厚。本研究的目的是评估使用来自以下加拿大省份的数据库（不列颠哥伦比亚省、安大略省、魁北克省和新斯科舍省）进行情绪和焦虑障碍监测的这些数据的有用性。
使用来自医生账单和医院出院摘要以及社区诊所的数据，采用 ICD-9 诊断 296.0-296.9、311.0 和 300.0-300.9 的病例定义进行基于人群的记录链接分析。
新斯科舍省、不列颠哥伦比亚省和安大略省经治疗的情绪和/或焦虑障碍的患病率约为 10%，相似。魁北克省的患病率略低，为 8%。尽管数据编码存在差异，但各省份的研究结果在年龄和性别方面保持一致。总体而言，女性的情绪和焦虑障碍患病率高于男性。但是，当分别考虑治疗性焦虑症（300.0-300.9）和心境障碍（296.0-296.9、311.0）时，差异则更大。患病率从中年稳步上升，在 50 多岁和 60 多岁时下降，然后在 70 岁以上再次上升。
行政数据可以为监测经治疗的情绪和/或焦虑障碍提供有用、可靠和经济的信息来源。然而，由于诊断和数据采集的特异性不足，可能难以分别监测情绪和焦虑障碍。这些发现可能对澳大利亚情绪和焦虑障碍的监测具有启示意义，因为正在开发一个用于提取、链接和分析行政数据的国家网络。
