Obstetric Scoring for Recurrent Pregnancy Loss

Components of the Obstetric Score

• The American College of Emergency Physicians defines term births as births at or after 37 weeks of gestation, and preterm births as births before 37 weeks of gestation, which are important components of the obstetric score 1
• The Journal of Thrombosis and Haemostasis notes that second trimester losses should be counted in the obstetric score, highlighting the importance of accurate gestational age documentation 2

Clinical Implications of Accurate Scoring

• The American College of Rheumatology recommends antiphospholipid syndrome testing for patients with recurrent pregnancy loss, which is guided by accurate obstetric scoring 3
• The American College of Rheumatology also suggests that thrombophilia testing may be considered in selected cases of recurrent pregnancy loss, based on the patient's obstetric history 2
• Accurate scoring guides testing for antiphospholipid syndrome, including testing recommended by the American College of Rheumatology, and informs the need for anticoagulation with low-dose aspirin and/or heparin in patients with antiphospholipid syndrome 3, 4
