Abstract

Predicting gestational diabetes by clinical scoring is meant to improve the efficiency of screening. The aim of this study was to determine the usefulness of clinical scoring in a Malaysian population. Using a retrospective cohort of 1997 women, a predictive model was developed and validated on a separate set of 1,000 patients. The efficiency of screening with risk scores was then compared with universal screening. The model derived was well calibrated ( p = 0.80) with an AUC 0.74 (95 CI 0.71 to 0.76). Different combinations of thresholds for the risk score produced a screening reduction between 26 and 29 (Sensitivity- 86 compared to 97 from universal screening) in Strategy 1. Strategy 2 had no screening reduction but had a higher sensitivity of 95 . The performance of the risk score was moderate and the screening reduction minimal. Therefore the usefulness of clinical scoring in our population is of limited value.
