1. An apparatus for use with a plurality of glucose monitoring devices, with a plurality of patients, and with an insulin delivery system, the apparatus comprising:
- one or more processors to;
obtain a plurality of observations of blood glucose concentrations of the plurality of patients received at the plurality of glucose monitoring devices;
compute a plurality of profiles of blood glucose concentrations based, at least in part, on the plurality of the observations;
for the plurality of patients, determine an associated plurality of unidimensional metrics indicative of glycemic health of the plurality of patients, the plurality of unidimensional metrics to be computed based, at least in part, on a convolution of a cost or loss function and the plurality of profiles of blood glucose concentrations of the plurality of patients;
rank the plurality of patients for treatment according to a triage policy based, at least in part, on the plurality of unidimensional metrics; and
control the insulin delivery system for balancing hypoglycemic and hyperglycemic tendencies in one of the plurality of patients based, at least in part, on the ranking of the plurality of patients for treatment according to the triage policy.

Abstract
Disclosed are methods, apparatuses, etc. for determination and application of a unidimensional metric for assessing a patient'"'"'s glycemic health. In one particular implementation, a computed metric may be used to balance short-term and long-term risks associated with a particular therapy. In another implementation, a computed unidimensional metric may be used to balance risks of hyperglycemia and hypoglycemia.
