*Purpose: Previous studies examining pregnancy related complications after solid organ transplantation (SOT) primarily relied on voluntary registries and meta-analyses. Herein, we investigated maternal delivery outcomes after SOT in a multistate cohort.

*Methods: We performed a retrospective cohort analysis of inpatient deliveries using Healthcare Cost and Utilization Project datasets from California (2005-2011), New York (2010-2013), and Florida (2005-2014). Multivariable logistic regression models were developed to compare peripartum complications of kidney and liver recipients with non-SOT women.

*Results: There were 339 deliveries from kidney recipients with median maternal age of 32 (28-36). Liver recipients had 163 deliveries with median maternal age at 27 (22-32). Non-SOT women had 5,650,795 deliveries with median maternal age of 28 (23-33). 86% of kidney recipients and 78% of liver recipients had one delivery. Kidney recipients were at increased risk for complications such as labor complications (OR: 3.75, 95% CI: 3.03-4.64, p<0.001), peripartum hemorrhage (OR: 2.21, 95% CI: 1.55-3.17, p<0.001), pregnancy related hypertensive disorders (OR: 8.91, 95% CI: 7.15-11.09, p<0.001), membrane-related disorders, including premature rupture of membranes and oligohydramnios, (OR: 1.64, 95% CI: 1.22-2.21, p=0.001), and caesarean section (OR: 2.65, 95% CI: 2.12-3.32, p<0.001) compared to non-SOT women. Liver recipients were also at increased risk for complications including labor complications (OR: 1.70, 95% CI: 1.21-2.39, p=0.002), peripartum hemorrhage (OR: 3.61, 95% CI: 2.29-5.70, p<0.001), pregnancy related hypertensive disorders (OR: 4.38, 95% CI: 3.06-6.27, p<0.001), and caesarean section (OR: 2.00, 95% CI: 1.46-2.73, p<0.001) compared to non-SOT women.

*Conclusions: Our results demonstrate an increased risk of delivery complications in SOT recipients. Additional research is needed to study the short and long-term neonatal outcomes of babies born to SOT mothers as well as the effect of pregnancy on graft survival and rejection to better characterize the relationships between pregnancy and transplantation.
