Continuous Glucose Monitoring for Personal Protective Equipment Evaluation

The Use of Continuous Glucose Monitors in the Care of Pregnant and Postpartum Women to Limit Frequency of Staff Exposure and Preserve Staff Personal Protective Equipment

Diabetes mellitus (DM) affects roughly 8% of pregnancies and is associated with significant perinatal and maternal morbidity. Current obstetric practice is complicated by the emergence of the SARS-COV-2 pandemic, resulting in morbidity and mortality secondary to complications of COVID-19. Care coordination among the teams caring for women admitted for antepartum, intrapartum, and postpartum care with suspected or confirmed COVID-19 is required to conserve PPE and minimize staff exposure. The investigators propose a pilot proof of concept randomized study to evaluate the utility of Dexcom-G6 continuous glucose monitors for assessment of glycemic control in pregnant and postpartum women with insulin-requiring diabetes mellitus during hospitalizations, as a proof of concept in the efforts to reduce the number of point of care glucose tests needed, reduce staff exposure, and conserve PPE use.

• Able to understand the study, and having understood, provide written informed consent in English
• Infants who survive to hospital discharge who are born to women enrolled in the study

Exclusion Criteria:

• Participation in another trial that may influence the primary outcome, without prior approval
