Claim 12:
13. An apparatus for use with a plurality of patients, for use with an insulin delivery system, and for use with one or more blood glucose monitoring devices, the apparatus comprising:
one or more processors configured to:
for each of the plurality of patients, (i) determine a profile of a blood glucose concentration of the patient based, at least in part, on a probability density function of a plurality of blood glucose concentration values collected at the one or more blood glucose monitoring devices, and (ii) determine a metric based, at least in part, on a convolution of a cost or loss function and the profile, wherein the metric is for balancing short-term and long-term risks associated with a therapy and is representative of a glycemic health of the patient, wherein the profiles of the plurality of patients are obtained under multiple predefined therapies, and wherein the loss or cost function substantially has the form:

Loss(GT)=log10(σ)2+[log10(μ)−log10(GT)]2, where:

GT is a target blood glucose concentration value;
μ is a computed mean of the plurality of blood glucose concentration values; and
σ is a measure of the statistical dispersion of the plurality of blood glucose concentration values; and

wherein the one or more processors are further configured to:
rank the multiple predefined therapies based, at least in part, on the metrics; and control the insulin delivery system for balancing hypoglycemic and hyperglycemic tendencies in the plurality of patients, based at least in part on the ranking of the multiple predefined therapies.
