Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what proportion of patients received treatment for bariatric surgery within 18 weeks of referral in (a) 2015-16, (b) 2014-15, (c) 2013-14 and (d) 2012-13.

NHS England publishes monthly data on referral to treatment waiting times to monitor performance against the legal right that patients have to start consultant-led treatment within a maximum of 18 weeks from referral for non-urgent conditions. The data that are published include the proportion of patients who waited within 18 high volume specialties but not individual procedures such as bariatric surgery. The information requested is therefore not available.
