The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Glen Watson dated September 2014
As Director General for the Office for National Statistics, I have been asked to reply to your recent Parliamentary Question asking the Secretary of State for Health how many women are known to have died of ovarian hyperstimulation syndrome in each year since 2000. (206969)
ONS holds mortality data for England and Wales based on the information provided at death registration. All conditions mentioned on the medical certificate of cause of death are coded according to the International Classification of Diseases (ICD). Since 2001, the ICD, Tenth Revision has been used to code deaths in which code N98.1 specifically identifies hyperstimulation of ovaries. Specific codes to identify this condition were not available in earlier revisions of the ICD.
Between 2001 and 2013 (the latest year available), two deaths have been registered in England and Wales where hyperstimulation of ovaries was recorded as the underlying cause of death (one in 2005 and one in 2006). In addition, one death was registered in 2008 which had hyperstimulation of ovaries mentioned on the death certificate, but this was not the underlying cause of death.
The number of deaths registered in England and Wales each year by sex, age and underlying cause, are published annually on the ONS website at:
