It is necessary to monitor autism prevalence in order to plan education support and health services for affected children. This study was conducted to assess the accuracy of administrative health databases for autism diagnoses. Three administrative health databases from the province of Nova Scotia were used to identify diagnoses of autism spectrum disorders (ASD): the Hospital Discharge Abstract Database, the Medical Services Insurance Physician Billings Database and the Mental Health Outpatient Information System database. ⋯ Sensitivity based on an ASD code in either the hospital or the physician billing databases was 62.5%. Administrative health databases are potentially a cost efficient source for conducting autism surveillance, especially when compared to methods involving the collection of new data. However, additional data sources are needed to improve the sensitivity and accuracy of identifying autism in Canada.

The current study provides a critical review of Canadian studies on ethnicity and mental health with respect to the definition, conceptualization and operationalization of ethnicity. It provides a discussion on the methodological issues related to these factors and their implications to guide future research and enable comparability of results across studies. Sociological Abstracts, PsycINFO, MEDLINE and CINAHL were used to identify relevant Canadian articles published between January 1980 and December 2004. The review highlights a number of key issues for future researchers to consider such as the need for: 1) clear rationales as to why ethnicity is important to their outcome of interest; 2) clarity on the definition of ethnicity, which affects its conceptualization and operationalization; 3) a theoretically driven conceptualization of ethnicity, which should be related to the research question of interest; and 4) clear rationales for the decisions made regarding the data source used, the operationalization of ethnicity, and the ethnic categories included in their studies.

Injuries are the leading cause of morbidity and mortality among Canadian adolescents. Rural adolescents may be disproportionally affected by these traumatic events. Differences in risk for injury between rural and urban adolescents remain understudied. ⋯ Several differences in risk for injury were documented by urban-rural geographic status. Adolescents from rural regions were more likely to report medically treated injury compared with the reference population from large metropolitan areas. These patterns of medically attended injury suggest that prevention and intervention programs could be better targeted to the needs of specific geographic populations of Canadian youth.

Routine surveillance of cases of disease can highlight geographic regions that need further study and intervention. Statistical disease cluster detection methods are one way to statistically assess the number of cases in administrative areas. Traditionally, disease cluster detection methods are used to monitor the incident cases of disease. ⋯ Analyses focus on the pediatric population and are adjusted by the age and gender distributions of subregional health authorities. Fifteen clusters of self-inflicted injuries are identified and, based on age and gender distributions, the clusters are not likely chance occurrences. We believe that these clusters represent areas of excessive self-inflicted injury and that special intervention programs should be considered.
