Abstract: Systems and methods are provided for optimizing short acting insulin medicament dosage timing relative to a meal event for a subject. Glucose measurements of the subject over a time course and the timing of the measurements are obtained. Meal events in the time course and information regarding when dosages were injected into the subject relative to the meal events is obtained. Bins, each for a different time range for when a dosage is injected relative to a meal event, are constructed. Each bin is assigned glucose measurements in one or more periods within the time course in which the subject injected the dosage within the time range associated with the bin. A glycaemic risk measure is determined for each bin with the assigned measurements and used to identify an optimal relative time range for the subject. This is communicated to a health care practitioner or to the subject.

Abstract: Systems and methods for evaluating insulin medicament dosage regimen adherence by a subject are provided. A description of metabolic events the subject engaged in is obtained. Each event comprises a timestamp and a classification that is one of insulin regimen adherent and insulin regimen nonadherent. Events are binned into consecutive time windows on the basis of time to obtain a plurality of subsets. Adherence values are computed. Each adherence value is for a subset and is computed by dividing the insulin regimen adherent events by the total number of events in the subset. Adherence values are combined into a composite value by a process that comprises downweighting a first adherence value, representing a first time window, with respect to a second adherence value, representing a second time window, when the first time window occurs in time before the second time window. The composite value is communicated as a single representation.

Abstract: A benchmarking approach is employed that compares advice output from one or more alternative treatment guidance algorithms with a current actual treatment in terms of treatment outcomes. Treatment outcome for the current strategy is reflected in an actual BG outcome or profiled. Treatment outcome for an alternative algorithm-generated dose advice is based on a patient-specific model. The two sets of outcomes can be compared directly or using performance scores as a weighted combination that penalises or rewards certain outcomes. A statistical test may be applied to the accumulated results (paired outcomes or scores) to determine whether the algorithm is superior to the user's current dosing strategy, or alternative strategies.

Abstract: A subject is prescribed short and long acting insulin medicament regimens. When a qualified fasting event occurs, the basal insulin sensitivity estimate of the subject is updated using (i) an expected fasting blood glucose level based upon the long acting insulin medicament dosing specified by the long acting regimen during the fasting event, (ii) glucose measurements contemporaneous with the fasting event and (iii) a prior insulin sensitivity factor. A basal insulin sensitivity factor curve is calculated from the updated basal insulin sensitivity estimate. A bolus insulin sensitivity estimate of the subject is updated upon occurrence of a correction bolus with a short acting insulin medicament using (i) an expected blood glucose level based upon the correction bolus, (ii) glucose measurements after occurrence of the correction bolus, and (iii) a prior insulin sensitivity factor. A bolus insulin sensitivity factor curve is calculated from the updated bolus insulin sensitivity estimate.

Abstract: Systems and methods are provided for adjusting a standing insulin medicament dosage regimen for a subject. Fasting events are identified using autonomous timestamped glucose measurements of the subject in a first data set. A second data set, from one or more insulin pens used to apply the standing regimen, comprises records, each record comprising a timestamped event specifying an amount of injected insulin medicament. Each fasting event is characterized as adherent or nonadherent. A fasting event is adherent when the second data set includes one or more records that temporally and quantitatively establish adherence with the standing regimen during the fasting event. Conversely, a fasting event is nonadherent when the second data set fails to temporally and quantitatively establish adherence with the standing regimen.

Abstract: Systems and methods are provided for adjusting a basal/bolus ratio in a standing insulin regimen for a subject that comprises daily amounts of basal and bolus insulin medicaments that define an initial basal/bolus ratio. A data set comprising glucose measurements of the subject with a respective timestamp for each such measurement over a time course is obtained. One or more fasting events are identified in the time course. A temporal glucose gradient is computed for each fasting event using the glucose measurements in the data set within the fasting event time period. Fasting event glucose gradients are used to determine whether to recommend adjustment to the basal/bolus ratio for the subject without change to the daily total insulin medicament. The recommended adjustment to the basal/bolus ratio is communicated when the determination is made to make the recommended adjustment to the basal/bolus ratio for the subject.

Abstract: Systems and methods are provided for adjusting long acting insulin medicament dosages for a subject. A plurality of timestamped glucose measurements of the subject and insulin injection data is obtained. A first glycaemic risk measures is determined, where the first risk glycaemic risk measure is i) glucose level variability across the glucose measurements, (ii) a variability in fasting glucose levels calculated from the glucose measurements, (iii) a minimum observed glucose measurement in the plurality of glucose measurements (iv) rate of change in ISF, or (v) adherence values. A fasting blood glucose target function is computed based upon at least the first glycaemic risk measure thereby obtaining an updated target fasting blood glucose level that is between a minimum and maximum target fasting blood glucose level. The long acting insulin medicament dosage is adjusted based upon the updated target fasting blood glucose level.

Abstract: Systems and methods are provided for optimizing basal administration timing in a standing basal insulin regimen of a subject. The regimen specifies a total amount of basal insulin medicament, one or more basal injection event types for a recurring period, and an apportionment of the total amount of medicament between the injection event types. Time stamped glucose measurements of the subject are obtained over a past time course comprising a plurality of instances of the recurring period. When the glucose measurements satisfy a stop condition, a recommended adjustment is determined that comprises a change in the number of injection event types in the regimen and/or a change in the apportionment of insulin medicament between injection event types. The recommended adjustment is communicated to the subject for manual adjustment of the regimen, an insulin pen charged with delivering the regimen to the subject, or a health care practitioner associated with the subject.

Abstract: Systems and methods for treating a subject are provided. A first dataset comprising timestamped autonomous glucose measurements of the subject over a first time course is obtained. A second dataset, associated with a standing insulin regimen for the subject over the first time course and comprising insulin medicament records, is also obtained. Each record comprises a timestamped injection event including an amount and type of insulin medicament injected into the subject by an insulin pen. The first and second datasets serve to calculate a glycaemic risk measure and an insulin sensitivity factor of the subject during the first time course, which are used to obtain a basal titration schedule and a fasting blood glucose profile model over a subsequent second time course for the subject. The model predicts the fasting blood glucose level of the subject based upon amounts of basal insulin medicament injected into the subject.
