Conditions

Diabetes Type 2 on Insulin, Hyperglycemia Due to Type 2 Diabetes Mellitus, Hypoglycemia (Diabetic)

Brief summary

The study compares two current practices for calculating insulin dose for admitted patients: flexible fixed mealtime dosing based on percent of meal eaten and carbohydrate counting based on amount of carbohydrates eaten.

Interventions

OTHERCarbohydrate-counting-based prandial rapid-acting insulin dosing

For each meal, the provider enters an insulin-to-carbohydrate ratio in the EHR. After the meal, nursing staff document the grams of carbohydrates consumed. The EHR calculates the rapid-acting insulin dose using the ordered insulin-to-carbohydrate ratio, along with any correctional insulin dose based on the pre-meal glucose value. The calculated insulin dose is then administered as soon as possible after meal completion.

OTHERFlexible fixed mealtime rapid-acting insulin dosing based on percentage of meal consumed

For each meal, the EHR calculates a full fixed prandial rapid-acting insulin dose from the provider-entered insulin-to-carbohydrate ratio, assuming a full meal contains 75 grams of carbohydrates and rounding to the nearest whole-unit dose according to the protocol. After the meal, nursing staff document whether the participant consumed 0%, 25%, 50%, 75%, or 100% of the meal. The EHR then instructs nursing staff to administer the corresponding proportion of the fixed dose as soon as possible after meal completion.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Time With Glucose in Target Range of 100 to 180 mg/dLFrom randomization to hospital discharge, up to 30 daysPatient-level percentage of time that glucose is within the target range of 100 to 180 mg/dL. This measure will be calculated using all glucose values obtained from randomization to discharge. For each patient, the time within range will be calculated using linear interpolation between consecutive measurements. For the percentage calculation, the numerator will be the calculated time within range, and the denominator will be the total time from the first glucose measurement after randomization to the last glucose measurement before discharge.

Secondary

MeasureTime frameDescription
Number of Hyperglycemia Events Greater Than 300 mg/dLFrom randomization to hospital discharge, up to 30 daysNumber of glucose values greater than 300 mg/dL from randomization to hospital discharge.
Rate of Hyperglycemia Events Greater Than 300 mg/dL Per Patient-DayFrom randomization to hospital discharge, up to 30 daysRate of glucose values greater than 300 mg/dL, calculated as the number of hyperglycemia events divided by the number of patient-days from randomization to hospital discharge.
Percentage of Time With Glucose Greater Than 300 mg/dLFrom randomization to hospital discharge, up to 30 daysPatient-level percentage of time that glucose is greater than 300 mg/dL, calculated using available glucose measurements from randomization to hospital discharge with linear interpolation between consecutive measurements.
Number of Hypoglycemia Events Less Than 70 mg/dLFrom randomization to hospital discharge, up to 30 daysNumber of glucose values less than 70 mg/dL from randomization to hospital discharge.
Rate of Hypoglycemia Events Less Than 70 mg/dL Per Patient-DayFrom randomization to hospital discharge, up to 30 daysRate of glucose values less than 70 mg/dL, calculated as the number of hypoglycemia events divided by the number of patient-days from randomization to hospital discharge.
Number of Severe Hypoglycemia Events Less Than 54 mg/dLFrom randomization to hospital discharge, up to 30 daysNumber of glucose values less than 54 mg/dL from randomization to hospital discharge.
Rate of Severe Hypoglycemia Events Less Than 54 mg/dL Per Patient-DayFrom randomization to hospital discharge, up to 30 daysRate of glucose values less than 54 mg/dL, calculated as the number of severe hypoglycemia events divided by the number of patient-days from randomization to hospital discharge.
Percentage of Time With Glucose Less Than 70 mg/dLFrom randomization to hospital discharge, up to 30 daysPatient-level percentage of time that glucose is less than 70 mg/dL, calculated using available glucose measurements from randomization to hospital discharge with linear interpolation between consecutive measurements.
Percentage of Time With Glucose Less Than 54 mg/dLFrom randomization to hospital discharge, up to 30 daysPatient-level percentage of time that glucose is less than 54 mg/dL, calculated using available glucose measurements from randomization to hospital discharge with linear interpolation between consecutive measurements.
Average Glucose During HospitalizationFrom randomization to hospital discharge, up to 30 daysMean glucose value during hospitalization, calculated using all point-of-care capillary and pertinent serum glucose values collected from randomization to hospital discharge.
Hospital Length of StayFrom randomization to hospital discharge, up to 30 daysDuration of hospitalization after randomization, reported in days
All-Cause 30-Day Hospital ReadmissionWithin 30 days after hospital dischargeOccurrence of all-cause hospital readmission within 30 days after hospital discharge.
All-Cause 30-Day Emergency Room VisitWithin 30 days after hospital dischargeOccurrence of an all-cause emergency room visit within 30 days after hospital discharge.
All-Cause MortalityFrom randomization through 30 days after completion of study participationOccurrence of death from any cause during study participation or within 30 days after completion of study participation.
