Obstetrics is the field of medicine which encompasses the care of a woman during pregnancy and childbirth. In that way it is very unique, as when assessing these patients, your actually also assessing another the child. Consequently, the approach to history taking in Obstetrics whilst similar to other fields of medicine, includes a number of additional components.
The following is a guide to taking an Obstetric History, that will ensure you miss none of the key components.
Presenting Complaint
What is the problem that brought you to the hospital/clinic?
Some common presenting complaints include;
- Bleeding
- Abdominal Pain
- Hypertension
- Physiological complaints due to pregnancy
The patient may also be presenting as part of standard antenatal care (as per your local guidelines).
History of Presenting Complaint
Often there will be overlap between the history of the presenting complaint and the history of the current pregnancy.
History of Current Pregnancy
The history of current pregnancy should ideally be considered by the different trimesters to date. This will be useful for understanding common issues that arise at each stage, and also determining appropriate antenatal care and management.
General Questions
- Last menstrual Period (LMP)
- Estimated delivery date and approximate Gestational Age.
- Any concerns about your pregnancy
- What are your expectations regarding your pregnancy
First Trimester
- Further details regarding menstrual history (as below)
- Was the Pregnancy planned?
- How was the pregnancy confirmed?
- Signs and symptoms of pregnancy.
- How/has the pregnancy been dated (e.g. dating Ultrasound Scan)?
- What tests and scans have you had to date?
- Current medical illnesses and medications.
Second Trimester
- Any problems during second 3 months?
- Bleeding, vaginal discharge, urinary problems and so on.
- Last visit to the doctor?
- Has an Ultrasound scan (e.g. morphology scan) been done?
- Blood tests to date?
- Blood pressure?
- Growth of foetus, placenta location.
- Any issues after the first 6 months of your pregnancy?
- Bleeding, vaginal discharge, urinary problems, labour pain.
- Blood pressure
- Glucose
- Test results
- Any plans or ideas about method of delivery.
Gravidity: the number of times a woman has been pregnant, regardless of the outcome.
Parity: the number of times a female has given birth to a baby.
There are many different methods and protocols by which Gravidity and Parity are denoted, please be aware of your local policy and documentation guidelines.
A simple system commonly used in the UK is;
GPx+y
where
G= Gravidity, P = Parity: X = (any live or still birth after 24 weeks);
Y = (number lost before 24 weeks)
A woman who has never given birth is a nullipara, a nullip, or para 0.
A woman who has given birth two or more times is multiparous and is called a multip.
A woman in her first pregnancy and who has therefore not yet given birth is a nullipara or nullip. After she gives birth she becomes a primip.
A woman who has given birth once before is primiparous, and would be referred to as a primipara or primip.
Details of each pregnancy
- Dates of deliveries
- Length of pregnancies
- Singleton/twin and so on
- Induction of labour/Spontaneous
- Mode of Delivery
- Weight of babies
- Gender of babies
- Complications before, during and after delivery
- This question should be asked as some patients will not consider the above situations as pregnancy.
Any difficulties conceiving and any treatment/management to date for sub-fertility.
Past Gynaecological History
If it hasn’t been so already, you should first gain a Menstrual History as appropriate.
- 1st day of last menstrual period
- Duration and regularity of normal cycle
- Flow: heavy/light, clots, number of tampons/pads used
- Pain
Last Cervical Smear (Pap Smear): when and results.
Any Gynaecology Surgery?
- D&C
- Loop excision of transitional zone (LETZ)
- Previous C-Sections
Treatment or investigations for; ectopic pregnancy, pelvic inflammatory disease, infertility
