Background and aim 
•	There is a broad spectrum of chronic pain conditions, many with a high disease burden and no adequate standard of care.
•	The aim of this initiative is to provide a comprehensive and single point of reference for those chronic pain conditions with the highest burden of disease and unmet medical needs, to increase knowledge and encourage cross-team working.

Methods
•	Search strings were conducted using the most relevant publication data bases: Pubmed, Google Scholar and Embase
•	Structured interviews were conducted with more than 50 physicians across 7 European countries.
•	Indications were selected as those with a high burden of disease and (perceived) knowledge limitation index’.
•	The McGill pain score was utilised in an analysis of the selected conditions; where this was not available, correlation between McGill and NRS scores were estimated. 

Results
•	More than 500 conditions with pain as a key feature were identified, but only a few selected for different reasons
o	80 pain indications were placed for development into presentation modules following a standard format, including pathophysiology, clinical presentation, therapy, targets under research, unmet needs…
Conclusions
•	A high disease burden and unmet needs are apparent across many chronic pain conditions.
•	Differences but also, similarities have shown evident in different pain indications.
•	A strategy is being implemented to try to find the biological basis for those findings
•	The comprehensive repository is available online to pain researchers willing to join efforts to this initiative
