Abstract

Methods and systems for performing dose regimen modification are provided. The methods and systems perform operations comprising: receiving prescription related data for treating a patient with an expected level of efficacy, the prescription related data comprising medication regimen information including dose and interval; determining, using a model, a first amount of drug waste based on the prescription related data; comparing the first amount of drug waste to a threshold value; and in response to determining that the first amount of drug waste transgresses the threshold value, identifying an alternate medication regimen that is associated with a treatment having a given level of efficacy corresponding to the expected level of efficacy, the alternate medication regimen being associated with a second amount of drug waste that is lower than the first amount of drug waste; and triggering a notification associated with the alternate medication regimen.

in response to receiving the input, updating the prescription region to represent a drug dose vial combination and interval associated with a given alternate medication regimen represented by the given indicator and to represent drug waste associated with the given alternate medication regimen; and

triggering a machine notification causing a message to be displayed by a client device comprising the first amount of drug waste and the alternate medication regimen.

2 . The method of claim 1 , wherein the threshold value comprises 14 milligrams per dose or more.

computing a plurality of amounts of drug waste associated with the plurality of different medication regimens; and

selecting the alternate medication regimen from the plurality of different medication regimens based on the plurality of amounts of drug waste.

4 . The method of claim 3 , further comprising:

selecting the alternate medication regimen based on a criterion and the plurality of amounts of drug waste.

5 . The method of claim 4 , wherein the criterion comprises a waste value that is below the threshold value.

6 . The method of claim 4 , wherein the criterion comprises a zero waste value.

7 . The method of claim 4 , wherein the criterion comprises a combination of drug dose vials that is associated with a specified level of adherence, a specified level of side effects, injection quantity, or a specified level of efficacy.

8 . The method of claim 4 , wherein the criterion comprises an inventory parameter of drug dose vials.

9 . The method of claim 8 , wherein the inventory parameter comprises a rate at which a specified type of drug dose vial is dispensed or an amount of the drug dose vial that is available.

10 . The method of claim 4 , wherein the dose and interval of the prescription related data is a first dose and a first interval, wherein a first of the plurality of different medication regimens comprises a second dose and the first interval, the second dose being greater than the first dose, wherein a second of the plurality of different medication regimens comprises a third dose and the first interval, the third dose being less than the first dose, wherein a fourth of the plurality of different medication regimens comprises a second dose and a second interval.

11 . The method of claim 1 , wherein the prescription related data is associated with a drug comprising Monoclonal antibodies with linear pharmacokinetics.

12 . The method of claim 1 , wherein triggering the machine notification comprises causing the message to be displayed by the client device associated with a pharmacy benefit manager.

13 . The method of claim 1 , wherein the graphical user interface includes a third plurality of indicators that represent medication regimens of the first and second sets of alternate medication regimens having a specified type of drug dose vial.

14 . The method of claim 1 , wherein the machine learning technique comprising a neural network.

15 . The method of claim 1 , wherein training the model by performing operations comprises:

obtaining a batch of training data comprising a first set of the plurality of training prescription related data features and alternate medication regimens that have been selected;

processing the first set of the plurality of training prescription related data features by the machine learning technique to generate an estimated alternate medication regimen;

computing a loss based on a deviation between the estimated alternate medication regimen and the corresponding alternate medication regimens of the first set of the plurality of training prescription related data features; and

updating parameters of the machine learning technique based on the computed loss.

16 . A system comprising:

receiving prescription related data for treating a patient with an expected level of efficacy, the prescription related data comprising medication regimen information including dose and interval;

determining, using a model that comprises a machine learning technique trained to establish a relationship between a plurality of training prescription related data features and alternate medication regimens, a first amount of drug waste based on the prescription related data;

comparing the first amount of drug waste to a threshold value;

in response to determining that the first amount of drug waste transgresses the threshold value,

identifying an alternate medication regimen that is associated with a treatment having a given level of efficacy corresponding to the expected level of efficacy, the alternate medication regimen being associated with a second amount of drug waste that is lower than the first amount of drug waste; and

triggering a notification associated with the alternate medication regimen, wherein triggering the notification comprises generating a graphical user interface comprising a plurality of interactive regions representing different medication regimens, wherein the alternate medication regimens include at least one of a different dose, different interval or both, the graphical user interface comprising:

a prescription region representing the prescription related data and an indicator identifying the dose and interval, wherein the dose and interval of the medication related data is a first dose and a first interval,
