Abstract
Background: To minimize COVID-19 exposure, a modified 1-step strategy (MS) option was offered in addition to the standard (SS) GDM screening strategies (definitions in Fig 1A). Objectives: To assess the use of, and obstetrical and neonatal outcomes associated with, modified GDM screening during COVID-19. Methods: Primiparous pregnancies in Alberta, Canada (N=35,836; Jan 1, 2020 to Dec 31, 2021) were categorized by GDM screening status. Results: 87.4% underwent SS, 10.1% MS, and 2.5% had no GDM screening. MS use was highest in 2020-Q3 (second wave; Fig 1B). There was no difference in GDM rates between SS (11.1%) and MS (12.7%). MS screened women with GDM had worse outcomes than those screened using SS (Table). Conclusions: GDM screening rates were not impacted by COVID-19. The uptake of MS was low to modest and appeared to identify higher-risk GDM women. Disclosure V.Liyanage: None. O.Barrett: None. D.P.Ngwezi: None. A.Savu: None.
