AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for pregnant women with type 2 diabetes who started prenatal care before 20 weeks. It compares two ways of checking blood sugar.
- Age
- 18 years or older
- Sex
- Women only
- Disease stage
- Pregnant with one baby (singleton), baby without anomalies, diagnosed type 2 diabetes, prenatal care started before 20 weeks of pregnancy
Main reasons for not taking part
- Type 1 diabetes
- Allergy to insulin
- Unable to wear a continuous glucose monitor
This trial only enrols pregnant participants. The registry sentence this rests on: singleton pregnancies

About the trial
What the trial wants to find out
The purpose of this study is to compare patient adherence to blood sugar monitoring during pregnancy using two different measurement methods in pregnancies complicated by pregestational type 2 diabetes (T2DM). Pregnant patients with T2DM are at risk of having larger babies, babies with low sugar levels in the first 24 hours of life, higher rates of cesarean delivery, stillbirth (death of baby inside the womb), and hypertensive or high blood pressure disorders of pregnancy, such as preeclampsia. Prior studies have shown that treating high blood sugars in pregnancy with medications can reduce these risks. To determine the amount of medication needed, recording of blood sugar levels is necessary. This trial aims to determine whether continuous blood sugar monitors have improved patient recording of blood sugar levels over finger stick blood sugar measurements.

Patients involved in the study will be assigned to either:
1. Fingerstick glucose monitoring (FSG) 2. Continuous glucose monitoring (CGM)
Patients will be randomize in a 1:1 ratio.
FSG Group: blood sugar is tested four times daily - once fasting and two hours after every meal (post-prandial). Blood will be tested using a glucometer, and values will be recorded in a blood sugar log from the time of enrollment to the time of delivery.
CGM Group: A CGM sensor will be placed on the patient's arm for blood sugar collection every 3-5 minutes. This data is sent to a phone application from the time of enrollment to the time of delivery. These sensors will need to be replaced every 14 days.
Percent adherence will be recorded from the time you were randomized to a study group until delivery.
The 2 groups in the trial
- Continuous glucose monitoringExisting treatment, for comparison
Patients in this arm of the study will use a continuous glucose monitoring device for glucose monitoring throughout their pregnancy, linked with a HIPAA-compliant digital application that will document measurements.
Treatment: Continuous glucose monitor
- Finger stick blood glucose monitoringExisting treatment, for comparison
Patients randomized to this arm will perform finger stick blood glucose measurements 4x daily (fasting and 2 hours after each meal) and document their measurements in a glucose log.
Treatment: Glucometer
