Against medical advice for induction of labor due to post-term pregnancies - the impact on pregnancy outcome.

OBJECTIVE

To determine the impact of deciding against medical advice and refusing labor induction in post-term pregnancies on pregnancy outcome.

METHODS

Maternal and neonatal outcomes of women who refused induction of labor due to post term pregnancy (study group) were retrospectively compared to a control group of women who agreed labor induction (1:2 ratio) in a university-affiliated tertiary single medical center.

RESULTS

A total of 83 women who refused labor induction were identified and compared to 166 womenwho consented to labor induction. Women who refused labor induction had higher rates of cesarean deliveries (21.7 vs. 10.2% p = .04), longer post-delivery hospitalization (2.9 vs. 2.4 days p < .05) and more advanced gestational age at delivery (41 + 6 vs. 41 + 4 days, p < .05). No significant differences were found in the rate of operative vaginal deliveries, need for antibiotics treatment or blood transfusion between the studied groups. Adverse neonatal outcomes among women who refused labor induction were significantly higher with higher rates of meconium (44.6 vs. 15.7%, p < .01), admission to NICU (9.6 vs. 5%, p < .01) and need for mechanical ventilation (4.8 vs. 0.6%, p < .01).

CONCLUSION

Refusing induction of labor due to post- term pregnancy is associated with higher rate of adverse maternal and neonatal outcomes, with a significant higher risk for cesarean section.
