Add features to check allergy or drug-drug interactions

[kristentaytok]

Problem Statement

Synthea has allergy profiles created by the drug_allergy module and a medications.csv file that provides start/stop dates.

To improve the realistic medication data in Synthea (i.e., simulate clinical decision making), the simulator needs to account for decisions to rule out certain medication therapies based on factors like allergies and drug interactions.

Criteria for Success

• Create a way for MDT (or Synthea) to adjust probabilities of medication orders based on a patient's drug allergy and active medications profiles (e.g., if a severe drug allergy then adjust the probability to 0%)

Additional Information

• By leveraging data from NLM
• Someone has created a drug interaction tool: https://github.com/uziminhas/synthea_NLM_api_demo - perhaps we can adapt, expand upon, or join forces to improve both features & integrate into Synthea
