Participant Flow

Mothers attending obstetrics clinics at Stanford University were approached if they met inclusion criteria. 119 mothers were approached, 66 declined to participate, 23 were lost to follow up after initially discussing the study, 6 were unable to participate because research staff were not available at the time of birth, and 3 were ineligible.

Measure
Remote Monitoring CGM Group
Participants wear a CGM that is blinded at bedside (to participant and clinical staff) but remotely monitored by study staff. If a blood sugar less than 46 mg/dl occurs, the study staff receive a notification and ask the clinical staff to perform a confirmation standard of care glucose test. Standard of care glucose test: If the CGM in the remote monitoring group detects a blood sugar less than 45 mg/dl, a confirmatory standard of care glucose test will be performed to confirm the low blood sugar.
Blinded CGM Group
Participants wear a blinded CGM during the study period. Values are blinded to study staff, participant, and clinical staff.

PRIMARY outcome

Timeframe: up to 8 days

Population: Participants in the remote monitoring group were eligible for analysis. 3 were excluded from the remote monitoring group for the analysis. Blinded CGM participants did not have a verification glucose check, thus sensor-detected hypoglycemia was not verified, and thus were not reported in the analysis.

Reported values in the table represent the cumulative number of hypoglycemic events detected by the sensor that were not detected by the hospital standard of care measures across all participants.

Standard of care glucose test: If the CGM in the remote monitoring group detects a blood sugar less than 45mg/dl, a confirmatory standard of care glucose test will be performed to confirm the low blood sugar.

SECONDARY outcome

Timeframe: up to 7 days

Population: Participants in the Remote Monitoring CGM Group were analyzed. 3 were excluded from the remote monitoring group for the analysis. Those in the blinded group were unable to be analyzed because the CGM was blinded and did not prompt a BG check.

SECONDARY outcome

Timeframe: up to 7 days

Population: 12 participants had sensor data for analysis. 3 were excluded from the remote monitoring group for the analysis. Blinded CGM participants did not have a verification glucose check, thus specificity could not be calculated on these participants.
