Calculation Methods
Numerator/ Denominator * 100
Numerator including inclusion/exclusion
Total number of screen-eligible women aged 52 to 69 years, who have completed at least one mammogram in the past two years
Includes:
- Ontario women (average risk and high risk) aged 52 to 69 years at the index date
- Index date was defined as the first screen date per person by screen date in Integrated Client Management System (ICMS) or by service date in OHIP in a two-year period
- OBSP mammograms for screening purposes were identified in the ICMS; all mammograms in ICMS were counted including those with partial views
- Non-OBSP mammograms were identified using OHIP fee code (X185 (diagnostic bilateral mammogram))
- Each woman was counted once regardless of the number of mammograms performed in a two-year period; if a woman had both a program and non-program mammogram within a two-year period, the program status was selected
Denominator including inclusion/exclusion
Total number of screen-eligible women, aged 52 to 69 years
Excludes:
- Women with a missing or invalid HCN, date of birth or postal code
- Women with a history of breast cancer using the diagnostic code (dxcode-174)

Caveats and Limitations
This indicator is based on OBSP and OHIP data, which have different data update cycles. As a result, mammography rates were underestimated during data periods when OBSP data was not yet available. In addition, in 2010 two additional OHIP fee codes were included to capture mammography rates. Historical data points from March 2011 through March 2013 have been updated to include the Ontario Breast Screening Program data, and to reflect the addition of OHIP fee codes (X175 and X178).
