Description

Disease coding and grouping, typically based on the International Classification of Diseases (ICD), is an important initial step in health statistics reporting. The development of a consistent classification scheme for mortality and morbidity is a challenge. The scheme needs to reflect health priorities of the province while remaining consistent with classifications in other jurisdictions to facilitate comparisons at national and international levels. The recent implementation of International Statistical Classification of Disease and Related Health Problems, 10th revision (ICD-10) has added to this challenge. Building on the work of national and international studies, this study defined 120 cause of death groupings with equivalent ICD-9 and ICD-10 coding to be used for routine health surveillance reporting in Alberta. This grouping and coding scheme is consistent with Statistics Canada mortality reporting. The study also presents comparability ratios from studies in Canada, the...

Description

This report is the first in a series of reports to examine data system quality issues in the health care system. It examines the number of cases of haemolytic uraemic syndrome (HUS) that were reported to the Alberta Communicable Disease Reporting System (CDRS) and to the Canadian Institute for Health Information (CIHI) Hospital Inpatient System – two data systems upon which many provincial and national health statistics are based. Results show a 3-4 fold difference in the reported cases of HUS between the two data systems in 1994-2003. Findings of this study have implications for the two data systems and for improved reporting of HUS and other diseases from the two systems.

Description

Most health statistics have a geospatial component. In order for health measures developed or used by different organizations to be valid and comparable, the measures should reference the same geopolitical areas. This report outlines the methodologies employed by Alberta Health and Wellness in calculations of health measures within geopolitical boundaries, and compares these to methods used by Statistics Canada and other agencies. It includes an analysis of the differences in methodologies and the differences in health measures that these different agencies have created, and presents recommendations for changes to the manner in which health measures are calculated in the future. The report is part of a family of reports that illustrates and documents the geographic methods required to properly analyze health data in Alberta.
