Daily Versus Every Other Day Glucose Monitoring in Gestational Diabetes Mellitus
- Conditions
- Gestational Diabetes
- Interventions
- Other: Glucose Monitoring
- Registration Number
- NCT04857073
- Lead Sponsor
- Icahn School of Medicine at Mount Sinai
- Brief Summary
Gestational diabetes mellitus (GDM) occurs secondary to carbohydrate intolerance in pregnancy. Screening of GDM occurs between 24 to 28 weeks gestation by a screening 1-hour 50g glucose challenge test and confirmed with a 100g 3-hour fasting glucose tolerance test. Once patients are diagnosed with GDM, they are instructed to check their fingerstick blood glucose four times daily, every day. There is insufficient evidence to determine the ideal frequency and timing of glucose monitoring in patients diagnosed with GDM and no absolute guidelines put in place by the American College of Obstetricians and Gynecologists (ACOG). The study team aims to confirm non inferiority on the patient population on the effects of daily (4x daily) versus every other day (4x daily) glucose monitoring in all patients diagnosed with GDM.
- Detailed Description
Gestational diabetes mellitus (GDM) occurs secondary to carbohydrate intolerance in pregnancy. Screening of GDM occurs between 24 to 28 weeks gestation by a screening 1-hour 50g glucose challenge test and confirmed with a 100g 3-hour fasting glucose tolerance test. In the study team's practice, once a patient is diagnosed with GDM, they are enrolled in the Diabetes in Pregnancy program, undergo nutritional education, diabetes education and have their care overseen by a Maternal-Fetal Medicine specialist. They are instructed to check their fingerstick blood glucose four times daily, every day. There is insufficient evidence to determine the ideal frequency and timing of glucose monitoring in patients diagnosed with GDM and no absolute guidelines put in place by the American College of Obstetricians and Gynecologists. In 2017, a randomized control trial was performed by Menedez-Figeroa et al, showing non inferiority in patients diagnosed with GDM who were instructed to perform every other day (4 time daily) glucose monitoring versus daily (4 times daily) glucose monitoring with their primary outcome being a 5% change in birthweight between groups at delivery. The study team aims to confirm non inferiority on the patient population on the effects of daily (4x daily) versus every other day (4x daily) glucose monitoring in all patients diagnosed with GDM with the primary outcome being a 0% difference in birth weight. The study team will be enrolling approximately 300 patients. If a patient is enrolled in the study, there will be no excursion from normally scheduled visits (including follow ups), medications regimens, or procedure (including ultrasounds). They will remain in the Diabetes in Pregnancy program throughout their pregnancy. Participants will be enrolled at the first visit with the high risk doctor, and they will be asked to perform standard (4x daily) fingerstick monitoring, or every other day fingerstick monitoring (4x daily, every other day). Data collected from the patient (including labs, and fingerstick glucose values) will not be exclusively for research purposes, and will be collected as a routine part of the patients care
Recruitment & Eligibility

- Female
- Target Recruitment
- 200
- Singleton pregnancies in women 18 years or older
- Diagnosis of GDM between 24 to 28 weeks gestation
- Preexisting diabetes mellitus or GDM diagnosed prior to 24 weeks by early GDM screening (including patients currently on insulin or any oral hypoglycemic agent)
- Diagnosis of GDM based on fingerstick paneling
- Women who are on chronic steroid therapy

- PARALLEL
- Arm && Interventions
Group Intervention Description Experimental group - glucose check every other day Glucose Monitoring Patients will be instructed to check their glucose every other day, 4 times glucose monitoring Control group - glucose check every day Glucose Monitoring Patients will be instructed to check their glucose 4 times a day, every day. This is currently the standard of care.
- Primary Outcome Measures
Name Time Method Birth weight Day 1 - day of delivery Fetal weight at time of delivery (grams).
- Secondary Outcome Measures
Name Time Method APGAR score Day 1 - day of delivery APGAR measures the baby's color, heart rate, reflexes, muscle tone, and respiratory effort and total score from 1 to 10, with higher score indicating better health outcomes
