Prostate cancer screening practices amongst physicians in the North Simcoe Muskoka Local Health Integration Network

Area of Science:

• Urology
• Preventive Medicine
• Family Medicine

Background:

• Prostate-specific antigen (PSA) screening is controversial due to over-diagnosis and over-treatment risks.
• The Canadian Task Force on Preventive Health Care (CTFPHC) recently recommended against routine prostate cancer screening.
• This study investigates the impact of CTFPHC recommendations on family physician practices in the North Simcoe Muskoka (NSM) LHIN.

Purpose of the Study:

• To assess the influence of CTFPHC guidelines on family physicians' prostate cancer screening practices.
• To evaluate physicians' perceptions of PSA screening efficacy and its survival benefits.
• To identify factors associated with differing screening practices and beliefs.

Main Methods:

• A survey was distributed to 439 family physicians and 21 residents in the NSM LHIN.
• Survey questions covered physician demographics, screening practices, and perceptions of screening efficacy.
• Response rate was 33.3%.

Main Results:

• 39.5% of physicians believed prostate cancer screening offers no survival benefit; 13.1% did not offer PSA screening.
• Younger physicians (<45 years, <10 years practice) were more likely to hold these beliefs.
• While female physicians were less likely to believe in screening benefits, no gender bias in actual screening practices was observed. CTFPHC recommendations minimally impacted practice patterns.

Conclusions:

• Prostate cancer screening practices among NSM LHIN family physicians are diverse and minimally affected by CTFPHC recommendations.
• Physician beliefs regarding screening efficacy significantly influence practice patterns.
• The controversy surrounding PSA screening persists despite updated guidelines.
