Avoidable Deaths From Preventable Causes
Lower rates are desirable.
(Number of deaths at age younger than 75 from preventable causes ÷ Total mid-year population younger than age 75) × 100,000 (age-adjusted)
Total mid-year population younger than age 75
Number of deaths at age younger than 75 from preventable causes
Methodology
Name
Avoidable Deaths From Preventable Causes
Short/Other Names
Avoidable Mortality From Preventable Causes
Description
Premature deaths that could potentially have been prevented through primary prevention efforts
Mortality from preventable causes is a subset of potentially avoidable mortality.
Rationale
Mortality from preventable causes focuses on premature deaths from conditions that could potentially be avoided through primary prevention efforts, such as lifestyle modifications or population-level interventions (for example, vaccinations and injury prevention). The indicator informs efforts aimed at reducing the number of initial cases, or incidence reduction, as deaths are prevented by avoiding new cases altogether.
Interpretation
Lower rates are desirable.

Updates
The definition of avoidable mortality was updated to align with the international definition. The updated definition is applied to the 2018 to 2020 rate onward. This update is the first since the Canadian version was originally developed in 2012. A notable change is the inclusion of COVID-19 deaths, which were assigned to the preventable category. For details regarding the updates, please refer to Summary of Revisions to Avoidable Mortality Indicators, 2022 (PDF).

Caveats and Limitations
It is generally acknowledged that not all deaths from potentially avoidable causes can actually be avoided. For example, some deaths from treatable causes may be unavoidable due to late diagnosis or concurrent health problems, while some deaths from preventable causes could be due to unpredictable events against which no protective measures could have been taken.
An upper age limit of 75 should not imply that some deaths in the population older than 75 could not be avoided. However, multiple comorbidities are common among older adults, making the assignment of a single cause of death challenging.
The indicators will be reviewed periodically to assess the upper age limit and potential new avoidable conditions due to better understanding of disease etiology or advances in treatment.
Trending Issues
An updated definition is applied to the 2018 to 2020 rate onward. Trend for smaller jurisdictions should be interpreted with caution.

Comments
The indicator is calculated based on 3 years of pooled data.
Avoidable mortality indicators were developed based on the Australian Potentially Avoidable Deaths indicator and the U.K. Office for National Statistics' list of causes of avoidable mortality, followed by expert review of the diagnosis codes and rationales for including each condition.
Causes of death were assigned to preventable and treatable subcategories based on 2 main mechanisms of mortality reduction: incidence and case-fatality reduction. These subcategories are mutually exclusive. In cases where a prevention/treatment overlap exists, the case was assigned to the preventable category; the exceptions were ischemic heart disease and stroke, where a random half of cases were assigned as preventable and the other half assigned as treatable. However, the mutually exclusive nature of the subcategories does not imply that all cases assigned to the preventable group do not have a treatable component, and vice versa.
More information about the indicator can be found in the In Focus section of Health Indicators 2012, available on CIHI's website.
