In this section

The PEN system is a global nutrition and dietetic resource that provides quick online access to the most up-to-date, critically appraised evidence on more than 190 nutrition and dieteticrelated topics all in one handy, easily searchable system.

In a nutshell, the PEN system condenses, summarises and presents the entire evidence-base on a particular nutrition or dietetic-related topic, therefore saving you time searching!

The PEN system applies the concept of ‘Knowledge Translation’ by synthesising the ever-changing and ever-expanding evidencebase using the highest quality research available and supporting you to apply that evidence-base in a practical way to nutrition and dietetic practice.

Why use the PEN system?

Dietitians and nutritionists are trusted by the public because their practice is evidence-based. However, maintaining an accurate overview of the evidence base in all general and specialised areasof dietetic practice can be a challenge. As a dietitian or nutritionist, PEN can support you by providing you with the evidencebase on a range of dietetic topics, offering answers to practice-based questions and providing access to an extensive list of practice tools and resources.

What does the PEN system do?

  • Applies the concept of ‘Knowledge Translation’.
  • Communicates dietetic and nutritional science in a transparent way.
  • Delivers critically-appraised dietetic evidence on over 190 topics.
  • Provides practice-based answers to dietetic and nutrition practice-based questions.
  • Promotes self-confidence when answering patient questions and queries by providing you with the evidence-base to help educate patients and clients.
  • Supports you to challenge misinformation, misconceptions and pseudoscience.
  • Helps to inform your clinical decision making as an evidence-based dietitian or nutritionist.
  • Is rapidly accessible online through your computer, mobile phone, home or on the road (for individual PEN subscriptions).

Why choose the PEN system?

  • The PEN database is extensive and covers a wealth of nutrition and dietetic-related topics, which is continually expanding…
  • All of the evidence in PEN is graded so you always know the quality of the evidence behind a particular nutrition or dietetic-related topic. Up until 2015, PEN used the A, B, C, D approach to grade evidence quality. In 2015, PEN adopted the GRADE approach (as used by BMJ Clinical Evidence, NICE, SIGN, WHO, and The Cochrane Library).
  • Each ‘Knowledge Pathway’ is continuously reviewed as the evidence changes, ensuring you are kept as up-todate as possible.
  • All references cited in PEN links to the abstract or full text so you can easily locate the original journal article or research paper.
  • PEN contains a number of useful features. For example, you can use the ‘Sort By – Country’ to search for ‘Related Tools and Resources’ relevant to your country. You can add PEN content to your ‘Favourites’ – this could be a particular ‘Practice Question’ or ‘Background’ section that you can save so you don’t have to re-search for the topic at a later date – saving you time!
