Revision History

This Core Indicator Product webpage is maintained by the Injury Prevention Subgroup.

Date	Review Type	Author	Changes	PDF
July 16, 2012	Formal Review	Injury and substance misuse prevention sub-group	New section on OPHS added Data source information updated to reflect use of IntelliHEALTH Ontario Updated analysis check-list, indicator comments, definitions, cited references and other references.
July 2009	Ad hoc		ICD-10 codes for Motor Vehicle Traffic Crashes - original codes were copied from an email which had errors. The revised codes are now consistent with the matrix as mentioned above available from: http://www.cdc.gov/nchs/data/ice/icd10_transcode.pdf
March 2009	Ad hoc		Updated ICD-10 codes for Motor Vehicle Traffic Crashes based on the matrix that the International Collaborative Effort on Injury Statistics has put together and posted on the US National Center for Health Statistics website. Changed title back from Motor Vehicle Crashes (title was changed in 2008).
November 2, 2019	Website Update and Ad Hoc Review	Suzanne Fegan, on behalf of the Injury Prevention subgroup; Caitlyn Paget, on behalf of the CIWG	Updated indicator definitions and documentation: Added Injury Intention as a subset analysis category. Revised the analysis checklist to remove out-of-date instructions for previous IntelliHEALTH platform, and move duplicate content to the appropriate Data Source page. Improved cross-references to supporting resources. Minor edits to content wording. Migrated to new website structure and format, including: Reorganized content to provide high-level information at a glance, and move in-depth analytic information into dedicated sections for users to access when needed. Generalized formulas for Age-Specific Rates, SRATE, and SMR. Renamed "Basic Categories" to "Recommended Subset Analysis Categories"; "Definitions" renamed to "Glossary". Added Ontario Trauma Registry reference information to the data source table. Replaced both "Cross-References to Other Indicators" and "OPHS" sections with "Related OPHS Topics" to crosslink with relevant Core Indicators webpages including OPHS program standard(s) and associated indicator(s). Added descriptive sub-headings to the Analysis Checklist and Indicator Comments sections. Removed "Corresponding Health Indicator(s) from Statistics Canada and CIHI" and "from Other Sources" sections. Updated Revision History table, and added PDF copy of previous version for reference.

APHEO's Core Indicators Project has been developed through collaboration across the field of public health in Ontario,

to provide standardized methodology for population health assessment, to measure complex concepts of individual and community health.
