Prescription decision support system and method using comprehensive multiplex drug monitoring
First Claim
1. A decision support method for optimizing medication dosages, the method comprising:
- measuring for each of a comprehensive plurality of medications from respective body fluid samples for each of a plurality of patients, and identifying actual concomitant medication levels for any one or more actual medications associated with the patients as a subset of the comprehensive plurality of medications;
iteratively developing proprietary drug interaction data in data storage over time, said drug interaction data based only on the identified concomitant medication levels and historical patient data for the respective patients comprising administered dosages of the one or more associated medications;
identifying one or more expected medications and desired exposure values for a first patient of the plurality of patients from at least an associated patient medical record;
determining one or more actual medications and exposure values for the patient from at least multiplex assay results associated with the patient;
with respect to each of one or more distinctions between the expected and actual medications and exposure values, implementing analyses of patient genotype, and of medications and metabolites as determined from the assay results, to distinguish between a non-compliance state for the patient and a compliance state for the patient further in view of high metabolizing characteristics as masking actual exposure values for an associated medication;
predicting potential medication levels corresponding to potential dosages for each identified expected medication and actual medication associated with the first patient based on at least the drug interaction data and the identified concomitant medication levels relative to the corresponding administered dosages;
generating a recommended dosage for each of the one or more identified expected medications and actual medications based on a desired outcome and the respective predicted medication level;
graphically generating a user interactive interface on a display unit comprising the recommended dosage values for each of the one or more identified expected medications and actual medications, and associated projected exposure ranges for each of the displayed medications;
enabling user manipulation of respective dosage values for any one or more of the identified expected and actual medications; and
dynamically calculating and displaying in real time projected exposure values for each of the one or more identified actual and expected medications based on the one or more user manipulated dosage values and on the drug interaction data.

Abstract
A decision support system and method for optimizing medication dosages includes comprehensive patient databases correlating medications and exposure values across data models having pharmacokinetic and pharmacodynamic dimensions. The system determines distinctions between expected and detected medications and exposure values for a patient, and further distinguishes between non-compliant patients from compliant patients having high metabolizing characteristics with respect to certain expected but undetected medications. The system links to and reconciles the patient medical record accordingly. Graphical user interfaces display recommended dosages and projected exposure ranges for the expected and detected medications. In an embodiment, the interface presents certain alternative treatment options determined as being available with respect to the expected but undetected medications. The user in an embodiment may manipulate or select respective nominal dosage values or alternative treatment options, wherein projected exposure values are dynamically calculated and displayed for each of the medications.
