Ovarian Hyperstimulation Syndrome
(asked on 19th June 2014) - View Source
Question to the Department of Health and Social Care:
To ask the Secretary of State for Health, how many women were admitted to hospital with ovarian hyperstimulation syndrome in each of the last five years for which figures are available; how many adverse incidents were recorded in licensed clinics in that period; and what the severity grading of each such incident was.
The Human Fertilisation and Embryology Authority (HFEA) has advised that the data it holds on these issues is as follows:
Year | Total number of incidents reported | Severity: Grade A | Severity: Grade B | Severity: Grade C | Not an incident/near miss |
2009-10 | 497 | 7 | 308 | 146 | 36 |
2010-11 | 586 | 1 | 292 | 255 | 38 |
2011-12 | 571 | 3 | 206 | 308 | 54 |
2012-13 | 503 | 0 | 183 | 261 | 59 |
2013-14 | 506 | 4 | 203 | 255 | 44 |
Of these, the number of cases of Ovarian Hyperstimulation Syndrome (OHSS) reported to the Authority is as follows:
Years | Number of OHSS | Moderate | Severe |
2009-10 | 121 | 1 | 120 |
2010-11 | 221 | 122 | 99 |
2011-12 | 241 | 196 | 45 |
2012-13 | 179 | 134 | 45 |
2013-14 | 192 | 142 | 50 |
The HFEA has also advised that licensed fertility clinics are only required to report instances of OHSS to the Authority that require a hospital admission with a severe grading, although in practice clinics often report moderate OHSS as well.
