Obstetricians and gynaecologists have been particularly affected by the increase in the cost and number of medical malpractice claims in Britain. US obstetricians and gynaecologists have experienced a disproportionately higher rate of claim than other practitioners in that country.

However, even if British malpractice claims do not reach the level of American claims, the effects of claims on the National Health Service, recruitment to obstetrics and gynaecology, and clinical practice are significant.
