![Page 4: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/4.jpg)
Potential Benefits of Screening
• Reduced mortality and morbidity from the disease, and in some cases reduced incidence
• More treatment options when cancer diagnosed early or at a pre-malignant stage
• Improved quality of life
• Peace of mind5
![Page 5: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/5.jpg)
Possible Harms of Screening
• Anxiety about the test
• False-positive results
‾ Psychological harm
‾ Labeling due to negative association with disease
‾ Unnecessary follow-up tests
• False-negative results
‾ Delayed treatment
• Over-diagnosis and over-treatment6

Screening Activity Report (SAR)Purpose Approach
Motivation: Enhance physician motivation to improve screening rates
Dashboard displays a comparison of a physician’s screening rates relative to peers in LHIN and province
Administration: Provide support to foster improved screening rates
Provides detailed lists of all eligible and enrolled patients displaying their screening-related history; clinic staff can be appointed as delegates
Failsafe: Identify participants who require further action
Patients with abnormal results with no known follow-up are clearly highlighted on the reports
Performance: Improve physician adherence to guidelines and program recommendations
Methodology based on the program’s clinical guidelines and recommendations for best practice

Burden of Disease
• 1 in 9 Canadian women will develop breast cancer in their lifetime
• In Ontario, an estimated 9,300 women will be diagnosed and 1,950 will die of breast cancer in 2013
• Most frequently diagnosed cancer in women
13
![Page 13: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/13.jpg)
Burden of Disease
• Breast cancer occurs primarily in women aged 50 to 74 (57% of cases); 8 in every 10 breast cancers are found in women aged 50+
• More deaths occur in women aged 80+ than in any other age group
• Reflects benefits of screening/treatment in prolonging life for middle-aged women
14
![Page 14: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/14.jpg)
Screening Rates
61% of eligible Ontario women age 50 to 74 years were screened for breast cancer in 2010–2011
• 71% screened in OBSP,
• 29% outside of OBSP
• The national target is to increase screening rates to ≥ 70% of the eligible population
15
![Page 15: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/15.jpg)
Challenges• Screening rates have slowed; lowest in
70 to 74 year (53%) followed by 50 to 54 year age groups (58%)
• Recruitment of under- and never-screened women (e.g., marginalized groups)
• Increasing awareness of and referrals to the high risk program among public and providers
• Controversy around screening women at average risk in the 40 to 49 age group
16
![Page 16: TriLHIN ICS Orientation Workshop July 16, 2014 Dr. Jan Owen, MD, CCFP, FCFP](https://reader036.vdocument.in/reader036/viewer/2022062409/5681459a550346895db28ce8/html5/thumbnails/16.jpg)

Clinical Case Study 3• Your 58-year-old average risk
asymptomatic patient in a small rural community asks about breast screening
• She wonders if she should take the longer trip to Community A where there is a new digital mammography unit; go to Community B, which is closer and has an analogue unit; or wait for the OBSP coach (with a digital unit) to come to town
What is your advice?
