BACKGROUND: Higher-order multiple (HOM) pregnancies are associated with significant maternal and neonatal morbidity, especially consequent to preterm birth. Multi-fetal pregnancy reduction (MFPR) may be provided, though its benefits in prolonging gestation and improving neonatal outcomes must be weighed against its risks.
AIMS: The aim was to compare outcomes of HOM pregnancies where expectant management was chosen (EM) with those where MFPR was provided.
METHODS: The method involved a retrospective study of HOM pregnancies referred to a single quaternary hospital between 2007 and 2016. The primary outcome was gestational age. Secondary outcomes included miscarriage, nursery admission, hospital stay, Apgar scores, early fetal loss, stillbirth, neonatal death and composite fetal loss.
RESULTS: Fifty-seven pregnancies were eligible for inclusion. Median gestation at birth (weeks) was significantly higher for MFPR (35.3 vs 33.1, P < 0.01). Pregnancies after MFPR were less likely to lead to preterm birth (63.2 vs 100.0%, P < 0.001), half as likely to birth before 34 weeks (31.6 vs 60.0%, P = 0.09) but similarly likely to extremely preterm birth (<28 weeks, 8.6 vs 10.5%, P = 0.58). Miscarriage was more likely after MFPR (13.6 vs 0%, P = 0.05). EM neonates were more likely to be admitted to the nursery (P < 0.01) and have longer hospital stay (29.6 vs 20.2 days, P = 0.05); however, they had similar Apgar scores.
CONCLUSION: Our study demonstrates that MFPR is associated with an increase in gestational age, with a reduction by almost half of births before 34 weeks, but no difference in extremely preterm births; the latter represents the highest risk group. This should be used to guide management counselling for HOM pregnancies.
