Abstract

Objective: This study investigates the cost effectiveness of gestational diabetes mellitus screening using the new International Association of Diabetes in Pregnancy Study Group (IADPSG) guidelines. Study Design: A decision analytic model was built comparing routine screening with the 2-hour (2h) oral glucose tolerance test (OGTT) vs the 1-hour glucose challenge test. All probabilities, costs, and benefits were derived from the literature. Base case, sensitivity analyses, and a Monte Carlo simulation were performed. Results: Screening with the 2h OGTT was more expensive, more effective, and cost effective at $61,503/quality-adjusted life year. In a 1-way sensitivity analysis, the more inclusive IADPSG diagnostic approach remained cost effective as long as an additional 2.0% or more of patients were diagnosed and treated for gestational diabetes mellitus. Conclusion: Screening at 24-28 weeks' gestational age under the new IADPSG guidelines with the 2h OGTT is expensive but cost effective in improving maternal and neonatal outcomes. How the health care system will provide expanded care to this group of women will need to be examined.
