Objective:
To estimate the likelihood of adverse outcomes in triplet pregnancies by a score comprising pregravid maternal characteristics.
Design:
A cross-sectional study.
Setting:
Triplets database collected by Matria Healthcare, Inc.
Patient(S):
A scoring system was constructed, assigning 1 point for the presence of a risk factor (nulliparity, stature <165 cm, and age <35 years) and 0 for the absence of a risk factor. Data related to 2,887 triplet sets were analyzed.
Intervention(S):
None.
Main Outcome Measure(S):
Total triplet birth weight <4,500 and delivery at 27-32 weeks.
Result(S):
We identified 18% of triplets' mothers (score 3) in whom the likelihood for adverse results is 50%-90% higher and the likelihood for optimal results is 40% to 70% lower than background rates.
Conclusion(S):
A pregravid maternal profile could estimate the likelihood of adverse outcomes and be used for consulting patients at risk of having or carrying a triplet pregnancy.
