From April the 1st 2006 Great Ormond Street Children's Hospital NHS Trust will be a national designated centre for the diagnosis and management of patients with Congenital Hyperinsulinism (CHI, formally called Nesidioblastosis and PHHI). The National Specialist Commissioning Advisory Group (NSCAG) has officially designated the endocrine department at Great Ormond Street Children's Hospital NHS Trust, as a national referral centre for the diagnosis and management of Congenital Hyperinsulinism. NSCAG is a Ministerial advisory body that focuses on the identification and funding of services where central intervention into local commissioning of patient services is necessary for reasons of clinical effectiveness, equity of access and/or economic viability. NSCAG aims to help patients by improving access to uncommon services, whilst at the same time seeking to sustain high levels of expertise at designated centres.

This will allow the endocrine department to improve the service they deliver by concentrating resources and giving patients more support, information and better treatment for Congenital Hyperinsulinism.
