Abstract

A method of administering insulin includes receiving blood glucose measurements of a patient at a data processing device from a glucometer. The blood glucose measurements are separated by a time interval. The method also includes receiving patient information at the data processing device and selecting a subcutaneous insulin treatment from a collection of subcutaneous insulin treatments. The selection is based on the blood glucose measurements and the patient information. The selection includes one or more of a subcutaneous standard program, a subcutaneous program without meal boluses, a meal-by-meal subcutaneous program without carbohydrate counting, a meal-by-meal subcutaneous program with carbohydrate counting, and a subcutaneous program for non-diabetic patients. The method also includes executing, using the data processing device, the selected subcutaneous insulin treatment.

receiving patient information; and

selecting a subcutaneous insulin treatment from a collection of subcutaneous insulin treatments based on the blood glucose measurements and the patient information, the selected subcutaneous insulin treatment includes one or more of a subcutaneous standard program, a subcutaneous program without meal boluses, a meal-by-meal subcutaneous program without carbohydrate counting, a meal-by-meal subcutaneous program with carbohydrate counting, and a subcutaneous program for non-diabetic patients, wherein during the standard subcutaneous program, the dosing controller;

determines a blood glucose type of the received blood glucose measurement; and

determines a correction insulin dose based on the blood glucose type by calculating;

CB_x=(BG_x−

BG_Target)/CF;

 

wherein CB_x is the correction dose based on blood glucose type X, BG_x is the blood glucose measurement, BG_Target is a target blood glucose value of a patient, and CF is a correction factor; and

executing the selected subcutaneous insulin treatment.

2. The system of claim 1, wherein the dosing controller determines a pre-meal correction bolus by calculating:

CB=(BG−

BG_Target)/CF

wherein BG is the blood glucose measurement, and BG_Target is a target blood glucose of the patient.

3. The system of claim 1, wherein the dosing controller:

receives a governing blood glucose value; and

determines an adjustment factor based on the received governing blood glucose value.

4. The system of claim 1, wherein the dosing controller:

receives a governing blood glucose value;

determines the governing blood glucose value is within a threshold range of values; and

sets an adjustment factor to a preconfigured adjustment factor based on the threshold range of values.

5. The system of claim 1, wherein the dosing controller:

receives a governing blood glucose value;

determines the governing blood glucose value is within one of multiple pre-configured ranges of values; and

sets an adjustment factor to a pre-configured adjustment factor associated with the pre-configured range of values that includes the governing blood glucose value.

6. The system of claim 1, wherein the dosing controller determines a Carbohydrate-to-Insulin Ratio based on the adjustment factor by calculating:

CIR=(CIR_Previous)/AF;

wherein CIR is the Carbohydrate-to-Insulin Ratio, CIR_Previous is a previously determined Carbohydrate-to-Insulin Ratio, and AF is the adjustment factor.

7. The system of claim 1, wherein the blood glucose type is associated with a blood glucose time associated with a time of measuring the blood glucose measurement, the blood glucose type selected from the group consisting of a:

midsleep blood glucose measurement, a pre-breakfast blood glucose measurement, a pre-lunch blood glucose measurement, a pre-dinner blood glucose measurement, and a bedtime blood glucose measurement, wherein the midsleep, pre-breakfast, pre-lunch, pre-dinner, and bedtime blood glucose measurements are scheduled in a daily repetitive rotational order.

8. The system of claim 1, wherein the dosing controller:

determines if a pre-breakfast blood glucose measurement has been received at the data processing device from the glucometer; and

when the pre-breakfast blood glucose measurement has been received;

selects a governing blood glucose as a lesser one of a previous midsleep blood glucose measurement or the pre-breakfast blood glucose measurement;

determines an adjustment factor for adjusting a current day'"'"'s recommended basal dose based on the selected governing blood glucose measurement;

retrieves a previous day'"'"'s bed time recommended basal dose; and

determines the current day'"'"'s recommended basal dose by multiplying the adjustment factor times the previous day'"'"'s bed time recommended basal dose, the current day'"'"'s recommended basal dose corresponding to an insulin dose of long-acting insulin to be administered to the patient at a configurable frequency of one, two, or three times per day.

9. The method of claim 8, wherein the dosing controller, when the pre-breakfast blood glucose measurement has not been received:

blocks a basal dose recommendation; and

transmits a warning to a display in communication with the dosing controller, the warning indicating the pre-breakfast blood glucose measurement has not been received and the blocked basal dose recommendation.

10. The system of claim 1, wherein the dosing controller:

receives a pre-breakfast blood glucose measurement from the glucometer;

selects a governing blood glucose as one of a previous midsleep blood glucose measurement or the received pre-breakfast blood glucose measurement;

determines an adjustment factor for adjusting a current day'"'"'s recommended basal dose based on the selected governing blood glucose measurement;

retrieves a previous day'"'"'s bed time recommended basal dose; and

determines the current day'"'"'s recommended basal dose by multiplying the adjustment factor times the previous day'"'"'s bed time recommended basal dose, the current day'"'"'s recommended basal dose corresponding to an insulin dose of long-acting insulin to be administered to the patient at a configurable frequency of one, two, or three times per day;

wherein the governing blood glucose is selected as the previous midsleep blood glucose measurement when the previous midsleep blood glucose measurement is less than the pre-breakfast blood glucose measurement; and

wherein the governing blood glucose is selected as the pre-breakfast blood glucose measurement when the breakfast blood glucose measurement is less than the previous midsleep blood glucose measurement unless the previous midsleep blood glucose measurement was accompanied by a correction insulin dose exceeding three units of insulin and an elapsed time between the correction insulin dose and the pre-breakfast blood glucose measurement is less than three hours.

11. The system of claim 1, wherein the dosing controller, when the determined blood glucose type is one of a pre-breakfast blood glucose measurement, a pre-lunch blood glucose measurement, or a pre-dinner blood glucose measurement:

after a subsequent blood glucose measurement associated with a subsequent blood glucose type is received, determines an adjustment factor for adjusting a next day'"'"'s recommended meal bolus for the determined blood glucose type governed by the blood glucose measurement for the subsequent blood glucose type; and

determines the next day'"'"'s recommended meal bolus at the time of day associated with the determined blood glucose type by multiplying the current day'"'"'s recommended meal bolus associated with the determined blood glucose type times the adjustment factor.

12. The system of claim 1, wherein during the subcutaneous program for non-diabetic patients, the dosing controller:

for each blood glucose measurement received by the dosing controller from the glucometer that is less than or equal to a threshold value;
