Systems and methods are provided for adjusting a standing insulin medicament dosage regimen for a subject. Fasting events are Device for adjusting a standing insulin regimen 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. Dosages in the standing regimen are adjusted using glucose measurements contemporaneous with adherent fasting events and by excluding glucose measurements contemporaneous with nonadherent fasting events.
