Postpartum Continuous Glucose Monitoring for Type 2 Diabetes Mellitus Risk Evaluation in Patients With Gestational Diabetes Mellitus: POSTPOD Trial
(POSTPOD)
What this study is about
This is a pilot study designed to evaluate the effectiveness of continuous glucose monitoring (CGM) within hours of delivery to predict long-term risk of Type 2 Diabetes Mellitus in patients diagnosed with gestational diabetes. Participants will be provided a CGM within 2 hours after delivery and wear the device for 24 hours. Participants will be instructed to peel off the device after 24 hours.
View original scientific description
This is a pilot study designed to evaluate the effectiveness of continuous glucose monitoring (CGM) within hours of delivery to predict long-term risk of Type 2 Diabetes Mellitus in patients diagnosed with gestational diabetes. Participants will be provided a CGM within 2 hours after delivery and wear the device for 24 hours. Participants will be instructed to peel off the device after 24 hours. Participants will also be asked to complete two surveys regarding their experience at 1-3 months postpartum and 12-14 months postpartum.
Interventions
DEVICE
Continuous Glucose Monistor
Continuous glucose monitoring sensor that provides 24/7 detailed glycemic information. Participants will wear for 24 hours and then be instructed to peel off.
Primary outcome measures
Clinical Efficacy Associated with CGM use immediately postpartum as compared to the 2 hr Glucose tolerance test
Time frame: 24 hours postpartum and 1-3 months postpartum
Regression analysis to assess strength and direction of the relationship between postpartum CGM data and 2 hr GTT
Clinical Efficacy Associated with CGM use immediately postpartum as compared to the HbA1c test postpartum
Time frame: 24 hours postpartum and 1-3 months postpartum
Regression analysis to assess strength and direction of the relationship between postpartum CGM data and HbA1c

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
