Pregnancy outcomes among visually impaired women in Washington State, 1987-2014.

BACKGROUND

Women with visual impairment may have reduced ability to access standard care resources, however, information on their pregnancy and neonatal outcomes is limited.

OBJECTIVE

To assess risk of adverse pregnancy and neonatal outcomes among visually impaired women in Washington State from 1987 to 2014.

METHODS

We conducted a retrospective cohort study using linked Washington State birth/fetal death hospital discharge records to compare outcomes among women with and without visual impairment noted at their delivery hospitalization. Pregnancy conditions and outcomes evaluated included gestational diabetes, pre-eclampsia, labor induction and cesarean delivery. Neonatal outcomes included preterm delivery and birth weight <2500 g. We assessed length of maternal and infant delivery hospitalization. We performed Poisson regression to estimate relative risks (RR) and 95% confidence intervals (CIs) for each outcome, adjusting for year of delivery, maternal age, and parity.

RESULTS

Most adverse pregnancy and neonatal outcomes were similar for visually impaired (N = 232) and comparison women (N = 2362). However, visually impaired women had increased risks of severe pre-eclampsia (RR 3.77, 95% CI 1.69-8.43), labor induction (RR 1.33, 95% CI 1.10-1.61) and preterm delivery (RR 1.60, 95% CI 1.06-2.42). They were also more likely to have delivery hospitalizations of 3 or more days following a vaginal (RR 1.86, 95% CI 1.41-2.47). Among cesarean deliveries, infants of visually impaired women had increased risk (RR 1.24, 95% CI 1.02-1.51) of hospitalization for 3 or more days postpartum.

CONCLUSION

Our findings may be useful for obstetric providers in counseling their visually impaired patients.
