The Global Guidelines in Dermatology Mapping Project



The Global Guidelines in Dermatology Mapping Project (GUIDEMAP) is an international effort to create and maintain an accessible web directory of clinical practice guidelines.

Formed from the review and interpretation of evidence, these guidelines are recommendations to guide best medical practice for skin diseases of the highest global disease burden.

We have organised the guidelines by condition:

GUIDEMAP identified these clinical practice guidelines through a comprehensive and systematic search of multiple medical databases, online resources, and direct contact with dermatology organisations worldwide.

Over time, GUIDEMAP will also provide an assessment of the quality of these guidelines. We aim to highlight best guideline development method practices within the field, and reduce research waste by highlighting potential areas of duplication globally.

By providing distilled, high quality guidance to the best medical care, we aim to empower both healthcare professionals and patients to ultimately improve the lives and wellbeing of patients with debilitating skin conditions.



We identified high priority skin conditions based on their global burden (Global Burden of Disease Study 2013 JAMA Dermatol. 2017 May 1;153(5):406-412). We then formulated a search strategy to identify these treatment guidelines.

We used search terms for the conditions combined with a guideline search filter in the following medical databases:

  • Embase
  • National Institute for Health and Care Excellence
  • NICE Evidence Search
  • Guidelines International Network
  • ECRI guidelines trust
  • Australian Clinical Practice Guidelines
  • TRIP database
  • DynaMed

We performed manual searches for guidelines on Google for each dermatological society that is listed under the International League for Dermatological Societies. We also contacted these societies to ask for the most current version of their guidelines.

We included any clinical practice guideline developed by local, regional, national or international groups or affiliated governmental organisations, published from October 2014 to 2019.

All of the guidelines we found were independently screened for inclusion by two researchers from the team. A third team member was also used if there were any disagreements in the original screening process.

We aim to appraise the quality of these guidelines using established instruments, such as the AGREE II checklist, the Institute of Medicine Criteria and Lenzer’s red flags. The protocol for this project is registered at the Open Science Framework (OSF).



We will publish links to our research relating to dermatological guidelines over the course of the project.

Pre-appraisal and Scoping Review publications

By mastering some of the knowledge, language and methodology used in the world of dermatology and research, he has been able to further serve those with atopic dermatitis by means of patient participation.

As such, he helps researchers apply for grants, (co-)publish (original) research, is involved in doing systematic reviews, advises the European Medicines Agency in scientific procedures and does patient-review for several medical journals.

For the Dutch Association of Dermatologists, he has co-authored four evidence based guidelines (topical corticosteroids, atopic eczema, hand eczema and rosacea), to ensure the patient perspective, and currently serve on two of its committees.
