Obstetric history taking  has a number of questions that are not part of the standard history taking format and therefore it’s important to understand what information you are expected to gain when taking an obstetric history. Check out the obstetric history taking mark scheme here.

Introduction

Introduce yourself – name / role

Confirm patient details – name / DOB

Explain the need to take a history

Gain consent

Ensure the patient is comfortable

Presenting complaint

It’s important to use open questioning to elicit the patient’s presenting complaint

“So what’s brought you in today?”   or  “Tell me about your symptoms”

 

Allow the patient time to answer, trying not to interrupt or direct the conversation

 

Facilitate the patient to expand on their presenting complaint if required

“Ok, so tell me more about that”  “Can you explain what that pain was like?”

History of presenting complaint

Ask the following questions for each symptom the patient is experiencing.

Onset when did the symptom start? / was the onset acute or gradual?

Duration – minutes / hours / days / weeks / months / years

Severity – e.g. if symptom is vaginal bleeding – how many sanitary pads are they using?

Course – is the symptom worsening, improving, or continuing to fluctuate?

Intermittent or continuous? – is the symptom always present or does it come and go?

Precipitating factors – are there any obvious triggers for the symptom?

Relieving factors – does anything appear to improve the symptoms e.g. an inhaler

Associated features – are there other symptoms that appear associated e.g. fever / malaise 

Previous episodes – has the patient experienced this symptoms previously?

Key symptoms to ask about in a pregnant patient

  • Nausea / vomiting – if severe may suggest hyperemesis gravidarum
  • Abdominal pain – may suggest the need for imaging
  • Vaginal bleeding – fresh red blood / clots / tissue
  • Dysuria / urinary frequency – urinary tract infection
  • Fatigue – may suggest anaemia
  • Headache / visual changes / swelling – pre-eclampsia
  • Systemic symptoms – fever / malaise

 

Ideas, Concerns & Expectations

Ideas – what are the patient’s thoughts regarding their symptoms?

Concerns – explore any worries the patient may have regarding their symptoms

Expectations – gain an understanding of what the patient is hoping to achieve from the consultation

 

Summarising

Summarise what the patient has told you about their presenting complaint.

This allows you to check your understanding regarding everything the patient has told you.

It also allows the patient to correct any inaccurate information & expand further on certain aspects.

Once you have summarised, ask the patient if there’s anything else that you’ve overlooked.

Continue to periodically summarise as you move through the rest of the history.

Signposting

Signposting involves explaining to the patient;

  • What you have covered – “Ok, so we’ve talked about your symptoms”
  • What you plan to cover next – “Now I’d like to discuss your past medical history”

History of the current pregnancy

Is this the patient’s first pregnancy? 

How was the pregnancy confirmed? – home testing kit / hCG blood test / USS

Last menstrual period (LMP) first day of the LMP

Was the patient using contraception? – are they still (e.g. COCP / implant / coil)

Estimated date of delivery (EDD) – estimated by scan or via dates (LMP + 9 months + 7 days)

Did the patient take folic acid during the first trimester? 


Any other scans or tests whilst been pregnant?
 – dating scan / anomaly scan

  • Growth of fetus – within normal limits?
  • Placental location – placenta praevia may alter delivery plans

 

Fetal movements – usually experienced at around 18-20 weeks gestation  

Labour pains – more relevant in the third trimester

Planned method of delivery – vaginal / c-section

Medical illness during pregnancy – if so are they taking any medications?

Previous obstetric history

Graviditydefined as the number of times a woman has been pregnant regardless of the outcome

Parity –  X = (any live or still birth after 24 weeks) |    Y = (number lost before 24 weeks)

 

Details of each pregnancy:

  • Date of delivery
  • Length of pregnancy
  • Singleton / twins / or more?
  • Spontaneous labour or induced?
  • Mode of delivery 
  • Weight of babies
  • Current health of babies

 

Complications of previous pregnancies:

  • Antenatal – IUGR / hyperemesis gravidarum / pre-eclampsia 
  • Labour – failure to progress / perineal tears / shoulder dystocia 
  • Postnatal – postpartum haemorrhage / retained products of conception 

 

Miscarriages / terminations – needs to be asked sensitively in an appropriate setting

Gynaecological history

Previous cervical smears when? / results? 

Previous gynecological problems & treatments – STDs / PID / Ectopic pregnancy

Current contraception – COCP / POP / Depot / Implant / Implanted uterine device

 

Gynaecological surgery:

  • Loop excision of transitional zone (LETZ)↑ risk of cervical incompetence
  • Previous C-sections – ↑ risk of uterine rupture / placenta accreta /adhesions

Past medical history

Relevant medical conditions

  • PE / DVT high risk for further events in following pregnancy
  • Diabetes – tight glycaemic control is essential – risk of congenital defects / macrosomia 
  • Epilepsy – some antiepileptics are teratogenic – needs neurology input
  • Hypothyroidism – TFTs need close monitoring – risk of congenital hypothyroidism
  • Previous pre-eclampsia higher risk to develop it in the current pregnancy

 

Other medical conditions

Any hospital admissions?when and why?

Surgical history – previous abdominal and gynaecological surgery of relevance

Immunisations up to date?

Drug history

Pregnancy medications:

  • Folic acid
  • Iron
  • Antiemetics
  • Antacids

 

Teratogenic drugs:

  • ACE inhibitors
  • Sodium valproate
  • Methotrexate
  • Retinoids
  • Trimethoprim

Document all regular medications

Over the counter drugs –  ensure nothing is unsafe / teratogenic

ALLERGIES

Family history

Inherited genetic conditions – cystic fibrosis 
Pregnancy loss – 
recurrent miscarriages in mother & sisters 
Pre-eclampsia – in mother or sister – increased risk

Social history

Smoking – can cause intrauterine growth restriction 

Alcohol – How many units a week? – can cause fetal alcohol syndrome

Recreational drug use – cocaine use can cause placental abruption

 

Living situation:

  • House / flat  – stairs / adaptations 
  • Who lives with the patient? – important when considering discharging home from hospital
  • Any carer input? – what level of care do they receive?

 

Activities of daily living:

  • Is the patient independent / able to fully care for themselves?
  • Can they manage self hygiene / housework / food shopping?
  • Is the pregnancy interfering with these daily activities?

 

Occupation – light duties / maternity leave

Systemic enquiry

Systemic enquiry involves performing a brief screen for symptoms in other body systems.

This may pick up on symptoms the patient failed to mention in the presenting complaint.

Some of these symptoms may be relevant to the diagnosis (e.g. vomiting in hyperemesis gravidarum).

Choosing which symptoms to ask about depends on the presenting complaint and  your level of experience.

 

Cardiovascular – Chest pain / Palpitations  / Dyspnoea /  Syncope / Orthopnoea  / Peripheral oedema 

RespiratoryDyspnoea / Cough / Sputum / Wheeze / Haemoptysis / Chest pain

GI – Appetite / Nausea / Vomiting / Indigestion / Dysphagia / Weight loss / Abdominal pain / Bowel habit 

Urinary –  Volume of urine passed / Frequency / Dysuria  / Urgency / Incontinence

CNS – Vision / Headache / Motor or sensory disturbance/ Loss of consciousness / Confusion

Musculoskeletal – Bone and joint pain / Muscular pain 

Dermatological – Rashes / Skin breaks / Ulcers
