RESUMEN
AIM: Selective screening for gestational diabetes is still a subject of debate. The aim of this study was to determine the effectiveness of a selective screening strategy for diagnosing gestational diabetes in our setting. This strategy rests on a scoring system that assigns women to different risk categories according to the presence of risk factors such as overweight, older age and ethnicity. METHODS: We compared the rate of diagnosed gestational diabetes according to universal screening and selective screening between two periods of time. RESULTS: The selective screening strategy allowed only 15% of women to avoid screening and was associated with a 50% decrease in diagnosed gestational diabetes. CONCLUSION: The two-threshold approach did not detect similar proportions of women with gestational diabetes compared with universal screening. Half the cases were missed and most women still needed to be screened.
