Building a global dietetic community of practice
Communities of practice, described as “groups of people who share a concern or a passion for something they do and learn how to do it better as they interact regularly”, have been around as long as human beings have learned together (1). The core elements of a community of practice include:
- a shared domain of interest, and a shared competence that distinguishes members from other people,
- a community that engages in joint activities and discussions, who help each other, share information, and learn together, and
- a practice, where members are practitioners with a shared repertoire of resources and a shared practice.
Since 2010, the Canadian PEN® Community has grown to include dietitians from Britain, Australia, New Zealand and Ireland. This past August, the Japan Dietetic Association and 200 of its members began participating in a one year trial of the PEN® Knowledge Database. The PEN® Team welcomes the Japan Dietetic Association and its members to the PEN® Community!

The PEN® Community Welcomes Japanese Dietitians to a PEN® Trial

As in other parts of the world, there are many reasons why the PEN® knowledge database can be beneficial in supporting the evidence-based practice of Japanese dietitians. Participants of the training sessions told us that PEN® is excellent with many practitioner benefits. Dr. Miki Miyoshi said the Power of PEN® video, which was translated into Japanese, was "very useful for our understanding. We found out the answers to what we want to know through PEN®! It helped our session".

Navigating PEN®: Finding PEN® Toolkit References
The PEN® Practice-based Evidence Toolkits or PEN® PETs are a ‘one-stop-shop’ for practice tools and information related to a particular knowledge pathway. PETs provide information in a format consistent with eNCPT (formerly called International Dietetics and Nutrition Terminology or IDNT) and with direct access to succinct information dietitians can more easily transfer to their practice. Click here for more background to PEN PETs.
Each toolkit is based primarily on the knowledge pathway’s practice questions (PQs) and therefore, the content from the PQs is not referenced in the toolkit. - Most of the information in the toolkit especially information in the Key Findings and Recommendations section, is a synthesis of the evidence found in the practice questions.
- The evidence in the practice questions is organized as evidence statements. The references to this evidence are found in the practice questions. Did you know - the number of references for each PQ can be anywhere from one to more than 100?!

Answer 17 questions to help young children get a healthy start with Nutri-eSTEP
The overall goal of the NutriSTEP® program is to improve the nutritional health of Canadian toddlers (18-35 months old) and preschoolers (3-5 years old) through the ethical use of valid and reliable screening tools. The unique parent-completed NutriSTEP® questionnaires were developed over several years to screen for a young child's nutritional risk and need for further advice and/or assessment.
Tool is well researchedRapid critical appraisal – digesting evidence fast!
Dietitians are familiar with exploring research to answer their practice-based questions.
But with tens of thousands of new nutrition citations published each year (1), it is easy to become over-whelmed with nutrition citations. How do dietitians decide which articles to acquire and review, so that they don’t just get any answer, but the best answer? Try a rapid critical appraisal.
Consider: What question did the study (or review) ask? Use PICO to compare your question (topic) with the PICO of the study. PICO stands for:
- P = Population,
- I = Intervention or Exposure,
- C = Comparison or Control,
- O = Outcome.
If a review article, was it a systematic review?
The main types of quantitative studies are:
- Intervention or Experimental studies (e.g. randomized controlled trial or randomized crossover study)
- Observational or Descriptive studies (e.g. cohort, case-control or cross-sectional studies)
- Randomized controlled trials (RCTs) are the best study design for examining the effect of a treatment or intervention. You can assume cause and effect when results are consistent across several well-designed RCTs for the same PICO conditions.
- Observational studies are practical for long follow-up, so frequently used for studying the effect of predictive risk factors on an outcome. Results can demonstrate correlations (or associations) but NOT causation.
- Research in the in vitro, ex vivo or an animal model can provide relevant information on potential mechanisms of action, but needs to be replicated in humans to be applicable to practice.
Did the observational study control for relevant confounding factors and report a large effect?
- A (good evidence) = results from studies of strong research design for answering the practice question, clear methodology, a large effect, and sufficient sample size.
- B (fair evidence) = results from studies of strong design with minor methodological concerns or weaker designs, but results have been confirmed in separate studies, have a large effect, and are generally consistent.
- C (limited evidence or expert opinion) = results from studies of weak design or there is substantial uncertainty due to inconsistencies among results from different studies or effect is not large.
- D (evidence extremely limited or lacking) = results from a single study with major design flaws or studies with contradictory results or animal / in vitro studies.
Is the treatment feasible in my practice?Will the potential benefits outweigh the harms?
If not, you are ready to move onto the next study!

PEN makes a splash at the 6th Asian Congress of Dietetics, Taipei
The Asian Congress of Dietetics is held every four years and was a wonderful opportunity to showcase the PEN® knowledge database to over 1000 delegates from across Asia in August, 2014. Hosted by the Chinese Dietetic Society, Taiwan, the theme was ‘Advancing health through innovative dietetic practice across Asia’. The Organising Committee led by Chairperson Dr Chwang Leh-Chii, developed an excellent program with sessions addressing the diverse areas of dietetics practice.
- Launch of the Power of PEN® video featuring dietitians speaking in different Asian languages, describing how they use the PEN® knowledge database in their practice. This video, developed by the Dietitians Association of Australia (DAA) staff, marketing guru Dr Sara Grafenauer and budding cinematographer Dr Paul Wilkinson, was a great hit.
- Promotion at the PEN exhibition booth featuring PEN merchandising material that included our adorable PENguins - a fantastic drawcard. With assistance from our travelling support crew, DAA’s PEN® Translational Research Leader Judy Bauer, CEO Claire Hewat and DAA President Liz Kellett, answered questions about PEN from the enthusiastic delegates.

- Delivery of a PEN® workshop attended by more than 40 delegates. This workshop highlighted the key features of PEN and was opportunity to extend an invitation to both Dietetic Associations and dietitians to join the PEN® Community. There has been interest from several Dietetic Associations in joining PEN since the Asian Congress.

"I really enjoyed working on the PEN research project this year. I learned a lot about PEN in general by having access to PEN content throughout my internship and often referred to it. Completing the literature reviews definitely enhanced my critical appraisal skills and has allowed me to keep a critical eye when researching other topics. The thoroughness of grading the evidence was a great learning experience and reinforced the value of this skill." - Shannon Smith, dietetic Intern - London Health Sciences Center
