Objective:
The purpose of this study was to determine the rates of obstetric hemorrhage and maternal mortality in women who are Jehovah's Witnesses and to evaluate a protocol that uses erythropoietin to optimize the red blood cell mass before delivery.
Study Design:
Obstetric outcomes were described for all of the women who were Jehovah's Witnesses and who delivered at Mount Sinai Medical Center during an 11-year period. The risk of maternal death was compared with our general obstetric population during this interval.
Results:
A total of 332 women who were Jehovah's Witnesses had 391 deliveries. An obstetric hemorrhage was experienced in 6% of this population. There were 2 maternal deaths among the women who were Jehovah's Witnesses, for a rate of 512 maternal deaths per 100,000 live births versus 12 maternal deaths per 100,000 live births (risk ratio, 44; 95% CI, 9-211). Erythropoietin was associated with a nonsignificant increase in hematocrit level.
Conclusion:
Women who are Jehovah's Witnesses are at a 44-fold increased risk of maternal death, which is due to obstetric hemorrhage. Patients should be counseled about this risk of death, and obstetric hemorrhage should be aggressively treated, including a rapid decision to proceed to hysterectomy when indicated.
