The training of registrars to become obstetrician-gynaecologists is performed in large hospitals, usually associated to an university. These hospitals are mostly level II and III hospitals to which more complicated cases are referred. The patients that registrars are exposed to are thus mostly selected to suffer from significant disease. This is true for both obstetrics and gynaecology. It is a logical consequence of this system that low risk patients and screening of well women for disease would be underrepresented in this setting.
