# Obstetrics Assessment

Antenatal obstetric assessment aligned with NICE NG201, stratifying
pregnancies into low, moderate, and high risk to allocate care pathway
(midwifery-led, obstetrician-led, or multidisciplinary) and to
schedule surveillance, screening, and birth planning.

## Scoring

**Instrument:** NICE NG201 Antenatal Risk Assessment.

- **Low Risk** — no obstetric, medical, or social risk factors →
  midwifery-led care.
- **Moderate Risk** — modifiable risk factors requiring obstetric input
  at key milestones.
- **High Risk** — significant pre-existing or pregnancy-related
  pathology → consultant-led/multidisciplinary care.

## What it covers

Maternal demographics; obstetric history; medical history (cardiac,
hypertension, diabetes, VTE); current pregnancy details (LMP, EDD,
dating scan); lifestyle and social factors; screening test results
(combined test, GTT, anomaly scan); mental health assessment (Whooley,
GAD-2); fetal assessment (growth, position, movements); birth
preferences; and care plan with follow-up.

## Relationship to prenatal-assessment

This assessment applies a formal NICE NG201 risk-stratification
framework to allocate care pathway; [[prenatal-assessment]] is a more
general antenatal evaluation covering similar ground with a simpler
Low/Moderate/High categorization not explicitly tied to a named NICE
guideline. Check which level of formality a given context requires.

## Common pitfalls

- **Fixing the care-pathway allocation at booking and never
  revisiting it** — risk can escalate during pregnancy (new
  hypertension, abnormal growth scan); the pathway allocation should be
  reviewed at each significant milestone, not just set once.
- **Skipping the mental health screen** — perinatal mental health
  (Whooley questions, GAD-2) is a required part of NICE-aligned
  antenatal care, not an optional add-on.
- **Treating "Low Risk" as meaning no further monitoring** — even
  low-risk pregnancies still follow a defined midwifery-led surveillance
  schedule; low risk changes who leads care, not whether monitoring
  happens at all.
