Background: Estimation of cost effectiveness and cost benefit are intrinsic to the design and evaluation of healthcare systems. The aim of most studies of gestational diabetes screening has been to modulate screening parameters to reduce the eligible population and therefore costs. We analysed the findings of a cross-sectional study of gestational diabetes mellitus carried out in Tehran to determine the screening method best suited to the socio-economic profile of our population.
Methods: 2416 pregnant women were universally screened in Tehran teaching hospitals. Each patient’s risk factors and laboratory results were recorded. The 50gGCT was used to screen and the 100gOGTT to confirm a diagnosis of GDM.
Results: Switching from the 130mg/dl to the 140mg/dl threshold, case-detection sensitivity declined by 12% (to 88%), with the per-pregnancy cost dropping from 30,410 to 25,641 Rials (from US$3.80 to 3.20) [-15.6%], and the cost per detected case from 644,488 to 619,500 Rials (from US$80.56 to 77.43) [-3.87%].
Conclusion: We recommend adoption of the universal screening approach in Iran for 4 reasons: (1) The high prevalence of gestational diabetes in the low-risk group (2) The poor level of healthcare provided in Iran compared with societies that have opted for the selective approach (3) The lower cost of screening and diagnostic tests in Iran compared with the aforementioned and (4) The high cost of treating the complications of diabetes.
