System and method of drug disease matching

Abstract

A computer implemented system and method for matching drugs and diseases involves matching drugs identified in a specific patient's prescription claim records with diseases associated with diagnosis codes. A weighted relationship is generated between the matched drugs and diseases by calculating a link weight in accordance with a preprogrammed formula for each of the diagnosis codes identified that is identified as associated with the disease identified and the drug. The link weight provides a statistical match association value to each of the matched diseases identified by way of a diagnosis code and the drug identified in the prescription claim.

         15 . A system comprising a processor coupled to a memory, the memory encoded with computer readable instructions that when executed cause the processor to:
 identify a prescription claim for a patient and a drug prescribed to the patient in accordance with the prescription claim;   identify at least one disease associated with the drug;   identify a plurality of diagnosis codes associated with the at least one disease; and   determine a link weight, wherein the link weight represents a degree of confidence that the drug is associated with the at least one disease and wherein the link weight provides a statistical match association value between the drug and at least one of a plurality of diseases identified by the plurality of diagnosis codes.   
     
     
         16 . The system of  claim 15 , wherein the computer readable instructions further cause the processor to provide a match strength value based on the link weight. 
     
     
         17 . The system of  claim 15 , wherein the link weight is based on a number of days between a date of service and a fill date, a physician, or combinations thereof. 
     
     
         18 . The system of  claim 15 , wherein the instructions that when executed cause the processor to identify at least one disease associated with the drug include instructions cause the processor to:
 identify the at least one disease associated with the drug using one or more lookup tables relating a drug ID number associated with the drug to one or more of the plurality of diagnosis codes.   
     
     
         19 . The system of  claim 15 , wherein the instructions that when executed cause the processor to identify a plurality of diagnosis codes associated with the at least one disease cause the processor to:
 search a medical claims history of the patient.   
     
     
         20 . The system of  claim 19 , wherein the instructions that when executed cause the processor to search a medical claims history of the patient cause the processor to:
 search a medical claims history of the patient based on a time frame.   
     
     
         21 . The system of  claim 15 , wherein the link weight is based on a plurality of values, each of the values having a respective level of importance. 
     
     
         22 . A method for establishing a relationship between drugs and diseases, comprising:
 identifying a prescription claim for a patient and a drug prescribed to the patient in accordance with the prescription claim;   identifying at least one disease associated with the drug;   identifying a plurality of diagnosis codes associated with the at least one disease; and   determining a link weight, wherein the link weight represents a degree of confidence that the drug is associated with the at least one disease and wherein the link weight provides a statistical match association value between the drug and at least one of a plurality of diseases identified by the plurality of diagnosis codes.   
     
     
         23 . The method of  claim 22 , wherein identifying a plurality of diagnosis codes associated with the at least one disease comprises:
 identifying the plurality of diagnosis codes in accordance with a plurality of search parameters; and   linking each of the plurality of diagnosis codes to the prescription claim.   
     
     
         24 . The method of  claim 22 , wherein determining a link weight comprises:
 determining a link weight based on a number of days between a date of service and a fill date, a physician, or combinations thereof.   
     
     
         25 . The method of  claim 24 , wherein determining a link weight based on a number of days between a date of service and a fill date, a physician, or combinations thereof includes:
 assigning a time weight based on the number of days.   
     
     
         26 . The method of  claim 22 , wherein identifying at least one disease associated with the drug comprises:
 identifying the at least one disease associated with the drug using one or more lookup tables relating a drug ID number associated to the drug and one or more of the plurality of diagnosis codes.   
     
     
         27 . The method of  claim 22 , further comprising:
 providing a match strength value based on the link weight.   
     
     
         28 . The method of  claim 27 , further comprising:
 ranking the match strength value against one or more other match strength values.   
     
     
         29 . One or more non-transitory computer readable storage media encoded with instructions executable by a processor for analyzing a mainframe system having a hierarchical storage unit for sensitive information, the instructions comprising instructions for:
 identifying a prescription claim for a patient and a drug prescribed to the patient in accordance with the prescription claim;   identifying at least one disease associated with the drug;   identifying a plurality of diagnosis codes associated with the at least one disease; and   determining a link weight, wherein the link weight represents a degree of confidence that the drug is associated with the at least one disease and wherein the link weight provides a statistical match association value between the drug and at least one of a plurality of diseases identified by the plurality of diagnosis codes.   
     
     
         30 . The non-transitory storage media of  claim 29 , wherein the instructions for identifying, at least one disease associated with the drug comprise instructions for:
 providing a match strength value based on the link weight, the match strength value indicative of a strength of association between the drug and the at least one of a plurality of diseases identified by the plurality of diagnosis codes.   
     
     
         31 . The non-transitory storage media of  claim 30 , wherein the instructions further comprise instructions for:
 ranking the match strength value against one or more other match strength values.   
     
     
         32 . The non-transitory storage media of  claim 29 , wherein the instructions for identifying a plurality of diagnosis codes for the patient associated with the at least one disease comprise instructions for:
 linking each of the plurality of diagnosis codes to the prescription claim.   
     
     
         33 . The non-transitory storage media of  claim 29 , wherein each diagnosis code of the plurality of diagnosis codes is associated with at least one of a plurality of medical claims, the plurality of medical claims including medical claims associated with a specific time frame, medical claims including a diagnosis code of a disease associated with the drug, medical claims indicative of face-to-face visits, or combinations thereof. 
     
     
         34 . The non-transitory storage media of  claim 29 , wherein the link weight is based on a number of days between a date of service and a fill date, a physician, or combinations thereof.
