Abstract

Methods, apparatuses, and systems are provided for determining whether to administer a medication dose as a single dose or whether to fractionate the single dose to be administered as at least two discrete doses. Embodiments include determining a first analyte level and a first rate of change of the analyte level; determining an initial medication dose based on one or more anticipated subsequent medication doses, the first analyte level relative to an analyte level threshold, and the first rate of change of the analyte level relative to a rate of change threshold; administering the initial medication dose; determining a second analyte level and a second rate of change of the analyte level based on subsequent analyte data; and determining a subsequent medication dose based on the second analyte level relative to the analyte level threshold and the second rate of change relative to the rate of change threshold.
