Making decisions about preventive health screenings can be complex. Balancing potential benefits and harms requires clear communication between clinicians and patients. This process, known as shared decision-making, is crucial, especially when recommendations are weak and the balance between benefits and harms is less certain. This is where knowledge translation (KT) tools play a vital role. These tools help bridge the gap between evidence and practice, empowering patients to make informed choices aligned with their values.
Understanding the Need for Knowledge Translation
Preventive health care often involves decisions with uncertain outcomes. While early detection through screening can be beneficial, it can also lead to false positives, overdiagnosis, and unnecessary treatment. Effectively communicating these complexities to patients requires more than simply presenting statistics. Patients need to understand the potential benefits and harms in a way that is relevant to their individual circumstances and preferences. KT tools facilitate this understanding.
Types of Knowledge Translation Tools
KT tools encompass a variety of resources designed to facilitate the implementation of evidence-based practice. These tools can be broadly categorized into:
- Implementation Tools: These are the most common type of KT tool used in preventive health care. They include:
- Printed Educational Materials: Guidelines, recommendations, frequently asked questions, and other resources, increasingly available electronically. These are often considered passive tools for disseminating information. (See Table 1 below)
- Decision Aids: These tools actively engage patients in the decision-making process. They provide user-friendly information about options, clarify values related to benefits and harms, and guide patients through the decision process. (See Table 1 below)
- Resource Planning Tools: These tools help with the logistics of implementing evidence-based practices, such as identifying necessary equipment or technology.
- Evaluation Tools: These tools assess the effectiveness of KT interventions and the quality of care.
Table 1. Common Implementation Tools in Preventive Health Care
| Factor | Printed Educational Materials* | Decision Aids |
|---|---|---|
| Target Audience | Patients, clinicians, caregivers | Patients, clinicians, caregivers |
| Format | Infographics (e.g., 1000-person diagram), FAQs, peer-reviewed publications | Infographics, algorithms, decision trees |
| Content | Health outcomes, benefits and harms, clinical risk scores, best practices, guideline recommendations | Explicitly stated decision, information on tests/interventions, benefits and harms, prompts to consider values, clinical risk scores |
| Passive Dissemination | Review articles, handouts | Distribution of decision trees |
| Active Implementation | N/A | Interactive discussions using decision aids |
*Printed educational materials can also be delivered via videos, online applications, etc.

The Importance of Using Effective KT Tools
KT tools are essential for translating complex medical information into understandable language, empowering patients to actively participate in their health care decisions. Studies have shown that decision aids, in particular, improve patient knowledge, reduce decisional conflict, and facilitate more meaningful conversations between patients and clinicians.
Qualities of a Useful KT Tool
Effective KT tools should have clear objectives, identify their target audience, provide instructions on how to use them, be based on credible evidence, and disclose any potential conflicts of interest. The International Patient Decision Aids Standards (IPDAS) Collaboration provides criteria for evaluating the quality of decision aids.
Conclusion
Knowledge translation tools are indispensable in preventive health care. They empower patients and clinicians to engage in informed shared decision-making, leading to better health outcomes and improved patient satisfaction. By facilitating clear communication and understanding, KT tools ensure that preventive health decisions are aligned with individual patient values and preferences.
