Abstract
The aim of this postal questionnaire survey was to identify facilities currently available for the care of pregnant diabetic women in the United Kingdom and determine how closely these reflect the standards recommended by The St Vincent Declaration Action Programme. A questionnaire was sent to a physician and an obstetrician in each of the 255 obstetric hospitals in the UK. Two hundred and forty-five (96.1%) hospitals replied, with most of these managing 20 or less insulin dependent diabetics per year. Of the hospitals, 58.4%, had a special combined diabetic antenatal clinic; 86.6% of the units had a single physician responsible for diabetic care, whilst more than one obstetrician was involved in 50.6% of the units. Prepregnancy counselling was provided in 87.4% of the hospitals. Home blood glucose monitoring was used in 97.9% of the units. Ideal mean pre- and postprandial blood glucose concentrations were 6.0 mmol/1 (SD 0.82) and 7.9 mmol/l (SD 0.91), respectively. Ultrasound was routinely used to assess fetal growth in 98.7% of the units. The mean gestational age for elective caesarean section was 38.2 weeks (SD 0.55), compared with 39.0 weeks (SD 0.35) for planned vaginal delivery. During labour, 98% of the units used a dextrose and insulin infusion, but only 53.7% of the units maintained an intrapartum maternal blood glucose of between 4 and 6 mmol/l. We conclude that there is widespread variation in the management of the pregnant diabetic patient, and much practice is suboptimal. Many of the recommendations of the St Vincent Declaration are not being met by current UK practice.
