To ask the Secretary of State for Health, with reference to the Answer of 9 May 2016 to Question 36176, what assessment his Department has made of the reasons for the increase in the count of finished admission episodes with a primary or secondary diagnosis of endometriosis, between 2010-11 and 2014-15.

The Department has not conducted a formal assessment of the reasons for the increase in hospital admissions with a primary or secondary diagnosis of endometriosis, between 2010-11 and 2014-15. However, it has asked the National Institute for Health and Care Excellence to develop a guideline on the diagnosis and management of endometriosis. This will include: use of staging systems to guide treatment decisions; timing of interventions; and pharmacological and surgical treatments. A consultation on the draft guidelines is scheduled to run from 27 February 2017 until the 10 April 2017, with an expected publication date of September 2017.
