Following this a GP has completed a number of six-month The Memory Hack Review placements in various hospital-based specialities - typical choices include obstetrics and gynaecology, paediatrics, psychiatry and/or general medicine. Finally, a year is spent in general practice as a "GP registrar" under the supervision of a senior GP. During this period, most doctors will take examinations to obtain the professional qualification of the Royal College of General Practitioners ("Member of the Royal College of General Practitioners", or MRCGP). Others qualifications, such as diplomas in child health, may also be obtained.
The GP is thus a doctor with a wide range of skills and experience, able to recognise and treat a multitude of conditions. Of course the necessity of this wide range of experience places limits on the depth of knowledge and skills that they can acquire. Therefore, if a patient's condition is rare or, complicated, or particularly severe and requiring hospital-based treatment, then they will refer that patient on to a specialist.
Focusing on mental health problems it will be noted that whilst the majority of GP's have completed a six-month placement in psychiatry, such a placement is not compulsory for GP's. However, mental health problems are a common reason for attending the GP and, subsequently, GP's tend to acquire a lot of experience "on the job".
