When to Use

When to Use

Standardized obstetric history intake for all pregnant patients.

Initial prenatal coding and clinical documentation.

Assessing obstetric risk based on prior pregnancy outcomes (e.g., prior preterm birth, spontaneous abortions).

Surgical and gynecological history assessment for non-pregnant patients.

Terminology Note

Gravidity and Parity are used to provide a shorthand summary of a woman’s obstetric history. While GPA is the most common shorthand, the GTPAL system is the clinical gold standard for detailed history.
