Variation in the commissioning of specialist weight management services and bariatric surgery across England: Results of a freedom of information‐based mapping exercise across the 42 integrated Care Systems of England

Abstract

Specialist weight management services including bariatric surgery are commissioned within regions of England called Integrated Care Systems (ICSs) with eligibility and treatment guidelines determined as part of the National Institute for Health and Care Excellence (NICE) guidance. Reported variation in commissioning and bariatric surgery eligibility criteria has not been previously mapped. Freedom of Information (FOI) requests provide a tool, supported by legislation, to ask questions of public authorities including ICSs such that they must respond accurately. FOIs were sent to all 42 ICSs in England asking 4 questions aiming to establish whether there is variation in the commissioning of specialist weight management services and the eligibility criteria for bariatric surgery across England. Responses were presented descriptively and mapped across England. Responses were received from 41 out of 42 ICSs, with 34 reporting that they provide commissioned medical weight management programmes and 38 funding bariatric surgery. Thirteen reported using criteria that were not compliant with NICE guidance. A large area of the country centred around the East of England does not have a bariatric unit reducing access to care. There is significant geographical variation in the availability of both bariatric and specialist medical weight management services across England, with large portions of the country without local access to a service or no service at all. Where services are available, there is significant inconsistency in eligibility for bariatric surgery despite nationally available guidance.
