The likelihood of adverse outcomes in triplet pregnancies estimated by pregravid maternal characteristics.
OBJECTIVE
To estimate the likelihood of adverse outcomes in triplet pregnancies by a score comprising pregravid maternal characteristics.


METHODS
A cross-sectional study.


METHODS
Triplets database collected by Matria Healthcare, Inc.


METHODS
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.


METHODS
None.


METHODS
Total triplet birth weight <4,500 and delivery at 27-32 weeks.


RESULTS
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.


CONCLUSIONS
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.
