What are the risk factors associated with hospital birth among women planning to give birth in a birth center in Washington State?

Adequacy of prenatal assistance in birth houses and causes associated with hospital transfers

OBJECTIVE

To analyze the adequacy of prenatal care in a Birth Center and the causes associated with maternal and newborn transfers to the hospital.

METHODS

Cross-sectional study of the care provided at the only Birth Center in Rio de Janeiro, from 2009 to 2014. Statistical analyzes were based on the χ2 test and Prevalence Ratio (PR).

RESULTS

Suitable prenatal care was predominant (42.8%) and there was no association (p = 0.55) with the transfers. Maternal transfer is caused by the ruptured amniotic sac (PR = 2.09, 95% CI 1.62-2.70) and altered fetal heart rates (PR = 3.06, 95% CI, 2.13-4.39). Newborn transfers are associated with the presence of meconium in the amniotic fluid (PR = 2.40, 95% CI 1.30-4.43); Apgar below 7 (PR = 5.33, 95% CI 2.65-10.73); and ventilatory assistance at birth (PR = 9.41, 95% CI 5.52-16.04).

CONCLUSION

Complications during intrapartum care are the causes associated with transfers.
