[Efficiency of a screening program for gestational diabetes].

From 1.1.1991-31.5.1989, we evaluated a selective screening system for detection of diabetes in pregnancy in an unselected consecutive population of 665 pregnant women. The screening procedure was carried out by the general practitioners and the midwives. The screening was based on clinical criteria for potential diabetes consisting of previous delivery of a large baby, a family history of diabetes and obesity combined with examination for glucosuria and determination of the fasting blood glucose concentration. Only 2% of the pregnant women were examined correctly and only two out of 665 women were found to have diabetes in pregnancy. The screening procedure failed when it was organised by general practitioners and midwives.
