1. 3.7.1
Definition
The percentage of Ontario men and women of screen-eligible age (ages 50-74), who have completed at least one FOBT in the prior two years.
Calculation
Number of people completing at least one FOBT in the prior 2 years/Target population (populations averaged over a period of time) x 100 = Population FOBT Participation rate (%)
Analysis
For calendar years 2002 to 2009 (02-03, 04-05, 06-07, 08-09)
Considerations
Include only FOBT as a primary screening test. The target population at increased risk (1st degree relative with previous colorectal cancer) cannot be accurately identified, and the provincial number of primary screening colonoscopies cannot be captured.
Indicator currently published in Cancer System Quality Index (CSQI).
International comparisons are most reliable without complex exclusion criteria (i.e., previous colorectal cancer or those who have had a colonoscopy).
Technical Specifications
Individuals with an FOBT are identified by:
GOO4 Lab.med.in office – occult blood
L179 ColonCancerCheck Fetal Occult Blood Testing (new in 2008)
L181 Lab Med – Biochem – Occult Blood
Multiple claims with unique Health Insurance Number (HIN), Service Date and Fee Code assumed to be a single claim
Registered Persons Data Base (RPDB) is used as the definitive source for date of birth, sex, and postal code
Local Health Integrated Network (LHIN) assignment is based on Postal Code Conversion file (PCCF+), version 5e
Exclusions:
Individuals not residing in Ontario or with an unknown place of residence.
Individuals aged 49 and under or 75 and over or of indeterminate age.
Individuals with missing date of birth, gender, or postal code in both OHIP and RPDB.
Numerator
Total number of age-eligible individuals who used and returned a program FOBT kit irrespective of result.
Note that each individual is counted once regardless of the number of tests performed.
Denominator
Total number of age-eligible individuals residing in Ontario within a given period adjusted to the 1991 Canadian population using the direct method.
Calculated as the average of the two years included in the period.

2. 3.7.2

Analysis
Age standardized % of women, men, total aged with ≥1 FOBT by LHIN
