O´Sullivan Test for screening patients with gestational diabetes mellitus.

Abstract

The objective of this study was to analyze the O'Sullivan Test for screening patients with gestational diabetes mellitus at the La Trinidad Teaching Medical Center. A descriptive, observational, retrospective cohort study was conducted. The average maternal age was 33.5 ± 4.64 years, with the 30-39 age group representing 70%. Most of the patients were primigravidas, making up 40% of the sample. The average gestational age at obstetric resolution was 39 ± 1 weeks, with the most common mode of delivery being cesarean section (70%). The average BMI was 27.97 ± 4.56 kg/m², with 43.33% of patients classified as overweight, making it an important risk factor for the development of gestational diabetes mellitus (GDM). The frequency of GDM at CMDLT was 0.46%. Additionally, 20% of patients experienced premature rupture of membranes. The sensitivity of the O'Sullivan Test was 100% (95% CI from 46.3% to 100%) and the specificity was 96% (95% CI from 93.6% to 97.1%). It was determined that the incidence of GDM was 0.46%, and the O'Sullivan Test demonstrated 100% sensitivity and 96% specificity, making it a precise and reliable test for diagnosing GDM.
