Refusal of blood transfusion by Jehovah's Witness women: a survey of current management in obstetric and gynaecological practice in the U.K.

BACKGROUND

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. We conducted a postal questionnaire survey of current practice among U.K. consultant obstetricians and gynaecologists to establish the practices that could contribute to poor outcomes in these women.

MATERIALS AND METHODS

The main variables of interest were: use of a multi-disciplinary approach; the acceptable minimum haemoglobin (Hb) concentration before vaginal delivery and abdominal hysterectomy as low to medium risk scenarios and open myomectomy as a high risk scenario for haemorrhage; Hb concentration thresholds for iron supplementation; and the use of oral iron, intravenous iron, erythropoietin and cell salvage as potential management tools.

RESULTS

The response rate was 28%. Sixty percent of gynaecologists and 85% of obstetricians reported having a protocol for the management of JW women. Forty-six percent of consultants adopt a multi-disciplinary approach which include anaesthetists and haematologists. A Hb concentration of >11-12 g/dL is considered the minimum acceptable level by a majority (47%) prior to normal delivery and by 42% of gynaecologists prior to abdominal hysterectomy. For open myomectomy 28% of gynaecologists prefer a minimum level of 11-12 g/dL but a further 31% of gynaecologists prefer a minimum level of 12-13 g/dL.

DISCUSSION

A small but substantial proportion of consultants do not have protocols, operate on JW women with low Hb concentrations, do not use a lower Hb concentration threshold for supplementation, and do not adopt a multi-disciplinary approach, all of which could contribute to the reported poor outcomes in these women.
