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.

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.
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.
Percentage of Time With Glucose in Target Range of 100 to 180 mg/dL
Patient-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.
Time frame: From randomization to hospital discharge, up to 30 days
Number of Hyperglycemia Events Greater Than 300 mg/dL
Number of glucose values greater than 300 mg/dL from randomization to hospital discharge.
Time frame: From randomization to hospital discharge, up to 30 days
Rate of Hyperglycemia Events Greater Than 300 mg/dL Per Patient-Day
Rate 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.
