I now have excellent content from authoritative textbooks. Let me compile the comprehensive answer:
Obstetrics & Gynaecology History Taking - MBBS Final Year
Here is a structured, examination-ready guide to taking an OB/GYN history, based on Berek & Novak's Gynecology and Schwartz's Principles of Surgery (Gynecology section).
Structure of the OB/GYN History
1. Patient Identification
- Name, age, occupation, marital status, religion
- Address, date of admission/consultation
2. Chief Complaint (CC)
State the presenting complaint in the patient's own words with duration. Common OB/GYN complaints include:
- Vaginal bleeding (normal or abnormal)
- Vaginal discharge
- Lower abdominal / pelvic pain
- Amenorrhoea
- Mass per abdomen
- Infertility
- Urinary symptoms (incontinence, frequency)
- Postmenopausal bleeding
3. History of Present Illness (HPI)
Explore the complaint using the SOCRATES framework:
- Site - pelvic, lower abdomen, vulval, etc.
- Onset - sudden or gradual
- Character - nature of pain/bleeding/discharge
- Radiation - to back, thigh, shoulder tip (ectopic)
- Associated symptoms - nausea, fever, dyspareunia, urinary/bowel symptoms
- Timing - relation to menstrual cycle, coitus, pregnancy
- Exacerbating/relieving factors
- Severity - impact on daily life
4. Menstrual History (ALWAYS ask in every OB/GYN history)
| Parameter | What to Ask |
|---|
| Menarche | Age of first period |
| LMP | Date of last menstrual period |
| Cycle | Length of cycle (days); normal = 21-35 days |
| Duration | Number of days of bleeding; normal = 2-7 days |
| Amount | Number of pads/day, passage of clots |
| Regularity | Regular or irregular |
| Dysmenorrhoea | Primary or secondary (suggest endometriosis, adenomyosis) |
| IMB / PCB | Intermenstrual or post-coital bleeding |
| Menopause | Age; method (natural / surgical / drug-induced) |
| PMB | Post-menopausal bleeding (always a red flag - cancer until proved otherwise) |
Mnemonic for menstrual history: "MLDCAR" - Menarche, LMP, Duration, Cycle, Amount, Regularity
5. Obstetric History (Gravida, Para, Abortus)
Use the G P A or GTPAL notation:
- G = Gravida (total number of pregnancies including current)
- T = Term births (≥ 37 weeks)
- P = Preterm births (28-37 weeks)
- A = Abortions (spontaneous + induced, < 28 weeks)
- L = Living children
For each pregnancy, record:
- Year and outcome (term/preterm, live/stillbirth, abortion/MTP)
- Mode of delivery - SVD, instrumental (forceps/vacuum), LSCS (indication)
- Birth weight
- Complications - PPH, sepsis, preeclampsia, gestational diabetes
- Neonatal outcome - NICU admission, neonatal death
"Number of pregnancies, dates, type of deliveries, pregnancy loss, abortion, and complications should all be systematically recorded." - Schwartz's Surgery
6. Sexual History
Ask sensitively and non-judgementally:
- Age of first intercourse (coitarche)
- Number of partners (current and past)
- Type of sexual activity (vaginal, anal, oral)
- Dyspareunia (superficial or deep)
- Post-coital bleeding
- Partner's health / STI risk
- Pregnancy intention / desires fertility
7. Contraceptive History
- Current method of contraception and duration of use
- Past methods and reasons for discontinuation
- Any complications from contraceptive use (IUD: pelvic pain, menorrhagia; OCP: thrombosis)
- IUCD in situ?
8. Gynaecological Screening History
- Last Pap smear / cervical smear - date and result
- HPV DNA testing / vaccination status
- Prior abnormal smear and any treatment (LEEP, CKC, cryotherapy)
- Last mammogram / breast ultrasound
9. Past Medical History (PMH)
- Diabetes, hypertension, thyroid disorders (strongly linked to menstrual irregularity and infertility)
- Bleeding disorders (von Willebrand disease - consider in menorrhagia)
- Autoimmune conditions (SLE - recurrent pregnancy loss)
- Tuberculosis (Asherman syndrome, infertility)
- Previous malignancies
10. Past Surgical History (PSH)
- Abdominal or pelvic surgeries (risk of adhesions, tubal damage)
- Previous gynaecological procedures: D&C, hysteroscopy, laparoscopy, myomectomy, LSCS
- Anaesthetic complications
11. Drug History
- Current medications including OTC drugs
- Hormonal drugs (OCP, HRT, progesterone injections)
- Anticoagulants (warfarin, heparin, aspirin - affect bleeding)
- Herbal medications
- Drug allergies (drug name + type of reaction)
12. Family History
Focus on:
- Breast cancer (especially first-degree relatives, premenopausal or bilateral)
- Ovarian / endometrial / cervical cancer
- BRCA1/BRCA2 mutations, Lynch syndrome
- Gestational trophoblastic disease
- Diabetes, hypertension, thyroid disorders
- Bleeding disorders
13. Social History
- Smoking (cervical cancer risk, placental problems)
- Alcohol use
- Illicit drug use
- Occupation (stress, chemical exposure)
- Marital status and relationship dynamics
- Domestic violence / sexual abuse (ask sensitively, alone with patient)
- Diet and exercise
- Housing conditions
14. Systemic Review
Briefly enquire about symptoms in other systems that may be relevant:
- Breast - lumps, nipple discharge, skin changes
- Urinary - frequency, urgency, stress incontinence, haematuria
- Bowel - constipation, blood in stool, rectal pain (endometriosis)
- General - weight loss, fatigue, appetite
Key Points for Exams
- Always ask LMP - essential for all women of reproductive age (rules out pregnancy before any investigation or treatment).
- Gravity/Parity notation - examiners specifically test this; be clear with G/T/P/A/L.
- Post-menopausal bleeding = endometrial cancer until proved otherwise.
- Menstrual history is distinct from obstetric history - do not conflate the two.
- Sexual history must be taken sensitively and confidentially - examiner looks for communication skills.
- Past surgical history in gynaecology must include prior uterine surgeries (scar uterus risk in subsequent pregnancies).
- For a pregnant patient (obstetric history), additionally ask about: antenatal visits, booking investigations, fetal movements, symptoms of preeclampsia (headache, visual disturbance, epigastric pain, oedema).
Specific Obstetric History (for Antenatal Patient)
Additional points for a pregnant woman:
| Domain | Key Questions |
|---|
| Current pregnancy | EDD (by LMP and USS), gestational age, ANC bookings |
| Antenatal investigations | Blood group, Rh factor, VDRL, HIV, blood sugar, anomaly scan |
| Symptoms | Morning sickness, bleeding (antepartum haemorrhage), PV discharge, fetal movements |
| Risk factors | HTN, GDM, thyroid, multiple gestation, placenta praevia |
| Social | Domestic situation, support at home |
