简要总结
Patient decision aids are tools that help guide individuals through a healthcare-related decision making process. They help users combine evidence-based information and recommendations by a health care provider with their personal needs, values and preferences. Through this project, Dr. Dobbins and her research team will explore whether the use of patient decision aids with high-quality and user-friendly summaries of research evidence, or summaries of research evidence alone, help to improve the quality of decision making by men facing prostate cancer screening decisions.
详细描述
Guidelines for prostate screening in Canada are based on low-moderate quality evidence of effectiveness and screening is associated with potential harms. Patient Decision Aids (PDAs) are tools that assist users to understand treatment options, risks and benefits to align decisions with values and preferences. The investigators would now like to know whether use of a PDA alongside evidence-based information provided through the McMaster Optimal Aging Portal, or simply access to evidence-based information alone, can help users to make informed decisions about prostate cancer screening in men.

研究组 & 干预措施
Evidence + PDA
Evidence-based information on PSA testing such as blog posts, plain language evidence summaries and web resource ratings (quality-appraised online resources), plus a blog post on PDAs and the relevant decision aid from the Portal database
干预措施: Patient Decision Aid (Other)
Evidence + PDA
Evidence-based information on PSA testing such as blog posts, plain language evidence summaries and web resource ratings (quality-appraised online resources), plus a blog post on PDAs and the relevant decision aid from the Portal database
干预措施: Evidence-based information (Other)
Evidence only
The same evidence-based information as group 1 (Evidence + PDA), but without the PDA to quantify the effect of accessing evidence through the Portal alone
干预措施: Evidence-based information (Other)
Attention control
Information on how to distinguish high from low-quality health information, not specific to cancer screening or PDAs
干预措施: Sham information (Other)
