Additional information that would seem to be fairly conclusive. At least at first reading. Marvin some of this might help support your Blog information. All of the web sites contain the reports and there is a handy 'pubmed' at the bottom that you can click on to read full reports.

Refusal of blood transfusion by Jehovah’s Witness women: a survey of current management in obstetric and gynaecological practice in the UK:
"Refusal of blood transfusion by Jehovah’s Witness (JW) women poses potential problems for obstetrics worldwide as haemorrhage remains a major cause of maternal morbidity and mortality. There is a general consensus that morbidity and mortality rates in association with childbirth and gynaecological interventions are higher in these women than in the general population.
A core belief among members of the Jehovah’s Witness (JW) faith is that they will not accept blood transfusion or its primary components, including red and white blood cells, platelets and plasma, even when such transfusion could be life-saving 1 . This poses potential problems for obstetric services worldwide because obstetric haemorrhage remains a major cause of maternal mortality and morbidity 2 , 3 . Indeed, there is a general consensus that morbidity and mortality rates in association with childbirth are higher in these women than in the general population 4 – 7 . In the largest observational study in the USA, Singla et al. reported that JW women were at increased risk of maternal death and that blood loss was the major factor 4 . In the UK, the largest descriptive obstetric study of JW reported a 65-fold increased risk of maternal death compared to the national rate. In addition, there was significant haemorrhage (>1,000 mL) in 6% of all of Caesarean sections 5 .
More recently, a study from the Netherlands reported that compared to the non-JW Dutch population, JW women had a 6-fold higher risk of all causes of maternal death, a 130-fold increased risk of maternal death because of major obstetric haemorrhage and a 3-fold higher risk of maternal morbidity because of obstetric haemorrhage 6 . Other earlier studies support these views, both for obstetric and gynaecological operations7.
It is estimated that there are approximately 6 million JW worldwide, about 150,000 of whom reside in the UK. Thus JW women constitute a significant group at high surgical risk. Apart from menstrual blood loss and childbirth, the vulnerability of JW women as a group is further increased by the significant proportion of African women who are members, since these women have a high incidence of fibroid disease, and, therefore, a preponderance of menorrhagia and iron deficiency anaemia."

STUDY DESIGN: Mount Sinai Medical Center
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 non significant 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.
More recently, a study from the Netherlands reported that compared to the non-JW Dutch population, JW women had a 6-fold higher risk of all causes of maternal death, a 130-fold increased risk of maternal death because of major obstetric haemorrhage and a 3-fold higher risk of maternal morbidity because of obstetric haemorrhage 6 . Other earlier studies support these views, both for obstetric and gynaecological operations7.
