  • 18 July 2022: The NELA team have successfully obtained exemption from the Confidentiality Advisory Group (CAG) from applying the national data opt-out for our audit. This means data can continue to be entered for ALL patients, regardless of their opt-out status. Contact us with any questions:
  • ​You can now DELETE CASES yourself within the NELA webtool. For any open case that has not yet been locked, use the 'Cannot Complete Audit' button within the data entry form to remove the case. 
  • ​The NELA team have run a series of quality improvement webinars over the past several years. You can watch content from all webinars on ourYouTube page
