title: Cost-effectivity analysis of one-step versus two-step screening for gestational diabetes.
abstract: OBJECTIVE
  Early diagnosis of gestational diabetes mellitus (GDM) is important for both maternal and fetal health. The literature has varying recommendations about one-step and two-step tests for GDM screening and diagnosis. The present study aimed to investigate the difference in the cost and duration of hospital stay of a one-step procedure compared to a two-step procedure, which is routinely performed in our hospital.
  
  
  METHODS
  The two-step procedure was performed in 2,724 pregnant women, and the one-step procedure was performed in 185 pregnant women. The one-step and two-step screening procedures for gestational diabetes were compared with respect to the duration of hospital stay and cost.
  
  
  RESULTS
  The test cost per woman was 0.75 TL less in the one-step procedure; however, the duration of the one-step test was 18.6 min longer, and the number of blood sampling procedures was 1.08 times higher.
  
  
  CONCLUSIONS
  The one-step method may be preferred over the two-step (or glucose challenge) test due to its diagnostic value and lower cost.
