Management of gestational diabetes by physicians in Turkey

We sought to investigate the practice patterns of clinicians (family physicians, internists and obstetricians) in Turkey in screening for gestational diabetes mellitus (GDM), management and monitoring of hyperglycaemia in pregnant women with GDM, and assessment of glucose tolerance in the postpartum state.

Between January and December 2007, current practices of Turkish physicians (n=434) were assessed by a questionnaire which was concerned with physician demographics and clinical practice including screening and diagnostic methods for GDM, management of GDM during pregnancy and postpartum assessment of glucose tolerance. The questionnaire was developed in respect to the recommendation of the Fifth International Workshop-Conference on GDM and the standards of the American Diabetes Association (ADA).

Although most of the physicians stated that they performed screening for GDM and postpartum screening for glucose intolerance in women with GDM, their screening practices vary. The proportion of women who were provided with a nutrition counselling by a registered dietician and a patient education by a trained nurse was low, especially in women treated by the family physicians. Home glucose monitoring was widely used in the management of GDM, however, postprandial glucose assays were used occasionally. Regular and NPH insulin preparations were the most preferred drugs to treat GDM. Internists were more likely to use insulin analogues. On the other hand, a significant number of physicians stated that they used oral antidiabetics (OADs). A considerable number of family physicians used OADs which have not been proved to be safe in pregnancy.

Our results suggest that there is considerable variation in the clinical practice patterns of physicians. An education program to enhance the clinical aptitude of physicians, particularly family physicians, in the medical management of GDM should be designed throughout the country.
