Participant Flow

Potential subjects were recruited from clinic; if more than 20 subjects were interested in participating in a given session, we preferentially enrolled those with a history of nocturnal awareness confirmed within the previous 2 months, (hypoglycemia unawareness confirmed with the Clarke screening test), or A1c \<8% needing \>0.7 units/kg day insulin.

Measure
All Participants
The subjects participated in three camps; each camp had approximately 20 subjects. There were two locations, one hosting two sessions. Each camp was approximately 5-6 days in length. Campers wore the device on alternating days, and hypoglycemia was treated with either mini glucagon or carbohydrates.

All Participants
n=57 Participants
The subjects were enrolled at three camps for diabetes; from each camp approximately 20 subjects were enrolled. There were two locations, one hosting two sessions. Each camp was approximately 5-6 days in length. Campers wore a continuous glucose sensor every day they were in the study. On alternate nights they had remote monitoring, this defined the primary treatment arms: remote monitoring or no remote monitoring. On alternating days of remote monitoring hypoglycemia was treated with either mini glucagon or carbohydrates, this was a secondary randomization.

PRIMARY outcome

Timeframe: 8 hours

Number of minutes with glucose reading \< 50 mg/dL. Each camper had Remote Monitoring nights and Control nights.

Outcome measures

Measure
Remote Monitoring
n=24 Hypoglycemic events
Subjects glucose data are remotely monitored at night using the University of Virginia (UVA) Diabetes Assistant (DiAs) Android Platform. Study staff intervenes with a fingerstick blood glucose measurement when sensor value falls below 70mg/dL. If fingerstick value is less than 70 mg/dL, hypoglycemic treatment is administered as below. Administer mini-glucagon as treatment for nocturnal hypoglycemia. Administer 0.01 cc per number of years in age via insulin syringe, subcutaneously. This amounts to 1 unit per age, for example: an 8 year old gets 8 "units" glucagon. Mini-glucagon: Mini dose glucagon given for glucose \<70 mg/dl at a dose of 1unit/year of age Remote monitoring: Provides real-time continuous glucose monitoring
Control
n=41 Hypoglycemic events
Subjects glucose data are remotely monitored at night using the University of Virginia (UVA) Diabetes Assistant (DiAs) Android Platform. Study staff intervenes with a fingerstick blood glucose measurement when sensor value falls below 70mg/dL. If fingerstick value is less than 70 mg/dL, hypoglycemic treatment is administered as below. Administration of carbohydrate per camp protocol to treat nocturnal hypoglycemia. Expected treatment is 15-45g. Remote monitoring: Provides real-time continuous glucose monitoring Carbohydrates and remote monitoring: 16 grams of carbohydrate with remote monitoring
Duration of Nocturnal Hypoglycemia
12.5 minutes
Interval 10.0 to 20.0

OTHER_PRE_SPECIFIED outcome

Timeframe: 8 hours at night

Prolonged hypoglycemia is defined as glucose readings of either \<70 mg/dL for greater than one hour on and off the device, \<70 mg/dL for greater than 2 hours on and off the device, \<50 mg/dL that lasted longer than 30 minutes on and off the device and readings of \<50 mg/dL for longer than an hour, again for both the control and the subjects that were remotely monitored with the device. Each camper had Remote Monitoring nights and Control nights.

Serious hypoglycemic events are recorded as AEs if the event required assistance due to altered consciousness and required another person to actively administer treatment. Hyperglycemic events are AEs if the event involved DKA, polyuria, polydipsia, nausea, vomiting, serum ketones, blood pH \<7.3, venous pH \<7.24, or serum bicarbonate \<15
