Introduction: OASIS is a complication of vaginal delivery. Although recurrence rates are low, women often feel apprehensive regarding subsequent births, with some wishing to delay future pregnancy. We aimed to evaluate contraceptive practices and interpregnancy interval of women who sustained OASIS.

Methods: We conducted a retrospective chart review of women who sustained OASIS from 2012 – 2017. We selected women who delivered during the same time period without OASIS as controls. We abstracted relevant demographic characteristics, delivery data, and documented postpartum contraceptive choice provided. We performed our analysis using independent two-sample t-test and chi-square test for unadjusted analyses and multivariable logistic regression for adjusted analyses, with alpha < 0.05.

Results: We included 314 women with OASIS and 297 without as controls. Women who experienced OASIS were more likely to be nulliparous, have an assisted vaginal delivery, and experience a wound complication. There were similar rates of postpartum contraceptive uptake in both groups (82% vs 84%, p=0.58). Greater than 50% of women in each cohort chose hormonal or long-acting contraceptives, with the majority choosing long-acting methods. Our multivariable regression showed no difference in method choice between groups. Of women with OASIS who had a subsequent delivery, 14% chose elective Cesarean section and the OASIS recurrence rate was 6%. Average interpregnancy interval was no different between cohorts (19.6 vs 20.7 months, p=0.53).

Conclusion/Implications: Although there were no significant differences in contraception uptake or type used in women who experienced OASIS, overall hormonal and long-acting contraception uptake was high. Experiencing OASIS does not appear to affect interpregnancy interval.
