21. A method, in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions executed by the at least one processor to cause the at least one processor to implement a cognitive medical treatment recommendation system, the method comprising: (5) (3)

performing, by the cognitive medical treatment recommendation system, natural language processing on an electronic corpus of natural language electronic documents to extract drug-to-drug interaction data;

ranking, by the cognitive medical treatment recommendation system, a set of candidate treatments for a medical condition of a patient based on an analysis of one or more electronic medical records (EMRs) associated with the patient and the extracted drug-to-drug interaction data, wherein ranking the set of candidate treatments comprises applying exclusionary weightings to confidence scores associated with candidate treatments that involve drugs that have drug-to-drug interactions with one or more other drugs associated with the patient as specified in the one or more EMRs; and

outputting, by the cognitive medical treatment recommendation system, a treatment recommendation based on the ranked set of candidate treatments.

22. The method of claim 21, wherein performing the natural language processing to extract the drug-to-drug interaction data comprises: (0) (2)

23. The method of claim 21, wherein the electronic corpus comprises natural language electronic documents comprising at least one of drug label documents comprising drug-to-drug interaction information, clinical statement documents comprising clinical statements from medical personnel describing drug-to-drug interactions, or patient statement documents comprising patient statements from patients describing drug-to-drug interactions. (0)

24. The method of claim 21, wherein performing natural language processing on an electronic corpus of natural language electronic documents comprises generating, for each drug-to-drug interaction specified in the extracted drug-to-drug interaction data, a drug interaction insight data structure, and wherein each drug interaction insight data structure specifies at least two drugs for which a negative result is determined to occur if the at least two drugs are administered to a patient. (1) (0)

25. The method of claim 24, wherein each drug-to-drug interaction insight data structure comprises a corresponding exclusionary weighting value applicable to scores generated for candidate treatments that include at least one of the at least two drugs specified in the drug-to-drug interaction insight data structure in response to a determination that the patient is also prescribed another of the at least two drugs. (1) (0)

27. The method of claim 21, wherein ranking the candidate treatments in the set of candidate treatments comprises, for each candidate treatment in the set of candidate treatments: (2) (5)

identifying at least one drug that is part of the candidate treatment;

identifying, for the at least one drug, at least one drug interaction data structure associated with the at least one drug;

identifying, for each drug interaction data structure, a delta exclusion factor specified in an associated drug interaction data structure;

determining, for each drug interaction data structure associated with the drug, whether a drug interaction represented by the drug interaction data structure applies to the patient based on the one or more EMRs associated with the patient and criteria specified in the drug interaction data structure; and

accumulating the delta exclusion factors for each drug interaction, represented by each of the drug interaction data structures, that apply to the patient to generate an exclusion weighting factor for the candidate treatment that is applied to a score for the candidate treatment.

28. The method of claim 27, wherein determining whether the drug interaction applies to the patient based on the one or more EMRs associated with the patient comprises modifying the delta exclusion factor associated with a drug interaction associated with the drug, based on a matching of portions of the one or more EMRs associated with the patient to criteria of the drug interaction specified in the drug interaction data structure. (0)

29. The method of claim 27, wherein the delta exclusion factors specified in the drug interaction data structures are learned through automated machine learning and natural language processing of the corpus of medical treatment content. (0)

30. The method of claim 21, further comprising: (0) (1)

31. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to implement a cognitive medical treatment recommendation system which operates to: (4) (3)

perform natural language processing on an electronic corpus of natural language electronic documents to extract drug-to-drug interaction data;

rank a set of candidate treatments for a medical condition of a patient based on an analysis of one or more electronic medical records (EMRs) associated with the patient and the extracted drug-to-drug interaction data, wherein ranking the set of candidate treatments comprises applying exclusionary weightings to confidence scores associated with candidate treatments that involve drugs that have drug-to-drug interactions with one or more other drugs associated with the patient as specified in the one or more EMRs; and

output a treatment recommendation based on the ranked set of candidate treatments.

32. The computer program product of claim 31, wherein the computer readable program further causes the cognitive medical treatment recommendation system to perform the natural language processing to extract the drug-to-drug interaction data at least by: (0) (2)

33. The computer program product of claim 31, wherein the electronic corpus comprises natural language electronic documents comprising at least one of drug label documents comprising drug-to-drug interaction information, clinical statement documents comprising clinical statements from medical personnel describing drug-to-drug interactions, or patient statement documents comprising patient statements from patients describing drug-to-drug interactions. (0)

34. The computer program product of claim 31, wherein the computer readable program further causes the cognitive medical treatment recommendation system to perform natural language processing on an electronic corpus of natural language electronic documents at least by generating, for each drug-to-drug interaction specified in the extracted drug-to-drug interaction data, a drug interaction insight data structure, and wherein each drug interaction insight data structure specifies at least two drugs for which a negative result is determined to occur if the at least two drugs are administered to a patient. (1) (0)

35. The computer program product of claim 34, wherein each drug-to-drug interaction insight data structure comprises a corresponding exclusionary weighting value applicable to scores generated for candidate treatments that include at least one of the at least two drugs specified in the drug-to-drug interaction insight data structure in response to a determination that the patient is also prescribed another of the at least two drugs. (1) (0)

36. The computer program product of claim 35, wherein the computer readable program further causes the cognitive medical treatment recommendation system to rank the candidate treatments at least by, for each candidate treatment, and for each drug-to-drug interaction insight data structure corresponding to a drug prescribed to the patient: (0) (2)

37. The computer program product of claim 31, wherein the computer readable program further causes the cognitive medical treatment recommendation system to rank the candidate treatments in the set of candidate treatments at least by, for each candidate treatment in the set of candidate treatments: (2) (5)

identifying at least one drug that is part of the candidate treatment;

identifying, for the at least one drug, at least one drug interaction data structure associated with the at least one drug;

identifying, for each drug interaction data structure, a delta exclusion factor specified in an associated drug interaction data structure;

38. The computer program product of claim 37, wherein the computer readable program further causes the cognitive medical treatment recommendation system to determine whether the drug interaction applies to the patient based on the one or more EMRs associated with the patient at least by modifying the delta exclusion factor associated with a drug interaction associated with the drug, based on a matching of portions of the one or more EMRs associated with the patient to criteria of the drug interaction specified in the drug interaction data structure. (0)

39. The computer program product of claim 37, wherein the delta exclusion factors specified in the drug interaction data structures are learned through automated machine learning and natural language processing of the corpus of medical treatment content. (0)
