Documentation of diagnoses within the increasingly more complex medical environment requires clear classification systems. In addition, classification systems for specialized areas such as pediatric endocrinology must allow the user to document all potential diagnoses in the specific field with sufficient detail to facilitate distinction between similar conditions. The multitude of existing classification systems for medical diagnoses indicates that there are various valid approaches to designing a classification system.

To address the need to develop a globally useful classification system for pediatric endocrinology, promote consistency of terminology, and facilitate global collaborative research efforts, a consortium of pediatric endocrine societies (the International Classification of Pediatric Endocrine Diagnoses [ICPED] Consortium) was formed (participating societies shown below).

Participating Societies

Chapters and Chapter Coordinators

The content of ICPED is based on the original work of a small group of members of the European Society for Paediatric Endocrinology (ESPE) that led to development of the original ESPE Classification1. The revision and expansion of the classification tool has been the voluntary work of international groups of pediatric endocrinologists with special expertise in particular topics, invited to participate from the world's pediatric endocrine societies. Fourteen groups were formed to revise and edit the chapters, each under the guidance of a chapter coordinator shown by the icon under each chapter title.

For certain diagnoses where available, the ICPED coding system provides hyperlinks to relevant codes in the International Classification of Diseases, Tenth Revision (ICD-10), and to the Online Mendelian Inheritance in Man (OMIM)® database.

The development of this tool was made possible by the financial support of the ICPED Consortium.

The web-based version of ICPED was developed by Sander Spaans of Growth Analyser BV, Rotterdam, The Netherlands.
