Obstetric history taking involves a series of methodical questioning of an obstetric patient with the aim of developing a diagnosis or a differential diagnosis on which further management of the patient can be arranged. This further treatment may involve examination of the patient, further investigative testing or treatment of a diagnosed condition.
There is a basic structure for all obstetric histories but this can differ slightly depending on the presenting complaint. Because of the nature of obstetrics there may not even be a presenting complaint. Expectant mothers receive antenatal check-ups and therefore may be referred because of the result of an examination or an investigation so the mother may be asymptomatic.
When taking any history in medicine it is essential to understand what the presenting complaint means (if any) and what the possible causes (differential diagnosis) of the presenting complaint may be. After all, it is the aetiology of a symptom that guides the physician's questioning
