The Registry relies on a complex reporting system and staff with expertise to accurately identify and classify cases of CJD. The Registry satisfies the criteria of flexibility and acceptability and has a high positive predictive value and representativeness. The sensitivity of the system could not be evaluated, as the rarity of the condition precludes an independent assessment of the incidence of CJD, but the incidence of CJD is comparable to that found in other countries. The time required to establish a definite diagnosis of CJD is approximately 2 months, impacting negatively on the timeliness of the system. In order to maximise the likelihood of detecting all cases of CJD in Australia in a timely fashion, suggestions are made for improving the system's sensitivity and timeliness of reporting as well as for using methods that allow meaningful comparisons of incidence between populations with different age structures.</p>","PeriodicalId":520897,"journal":{"name":"Communicable diseases intelligence quarterly report","volume":"26 2","pages":"265-72"},"PeriodicalIF":0.0,"publicationDate":"2002-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
