Designed in a question and answer format, the Knowledge Pathway represents a collection of Practice Questions, evidence-based answers, references, Practice Guidance Toolkits, Evidence Summaries, Backgrounds, Tools and Resources, and other related materials on a particular topic.
Knowledge Pathways are organized into four practice categories: Population Heath/Lifecycle, Health Condition/Disease, Food Nutrients, Professional Practice.
Generally formulated using the PICO approach (Population, Intervention, Comparison, Outcome), Practice Questions reflect the everyday practice situations faced by dietitians.
Practice Question Subcategories
To help you quickly find a relevant question, practice questions are organized by subcategories: Assessment, Diagnosis, Intervention, Monitoring, Evaluation (ADIME). Links are also provided to related Practice Questions from other Knowledge Pathways.
Key Practice Point
Based on a synthesis of the most valid, important and applicable evidence, the Key Practice Points provide a succinct evidence-based recommendation or “answer” to a dietetics practice question. Each key practice point is graded (A, B, C or D) based on the strength of the evidence used to formulate it.
Recommendations are clear, concise and actionable advice on whether to implement an intervention and, if relevant, under what conditions and how. They include five pieces of information:
1. the intervention and what it was compared to
2. the direction of the recommendation, i.e. for or against the intervention
3. the specific population of interest, which may also include a specific condition
4. the strength of the recommendation, i.e. “Strong” or “Conditional”
5. the overall quality of evidence and its corresponding symbol, i.e. “Very Low” ⊕⊝⊝⊝, “Low” ⊕⊕⊝⊝, “Moderate” ⊕⊕⊕⊝, “High”. ⊕⊕⊕⊕
Most recommendations will be one sentence long.
Remarks describe the justification for the recommendation and are concise, written in an active voice, and present information that would be most useful and relevant to a client.
A summary of the critically appraised evidence including type study, the population studied, number of subjects, methods used, main findings and study limitations.
