> How can a person possibly be better at knowing the graph of drug interactions better than a program can Than it should warn the human doctor before he write

  As I mentioned in another comment, this has already been happening for 10+ years. The eRx modules in all certified EHRs do automatically check for potentially harmful drug interactions. https://www.healthit.gov/test-method/drug-drug-drug-allergy-interaction-checks-cpoe https://www.healthit.gov/test-method/drug-drug-drug-allergy-... The problem is that the patient's chart may be erroneous or incomplete. So the system can only detect harmful interactions on entries that are fully populated with RxNorm (or NDC) concept codes. Human doctors are expected to manually reconcile the medication list before writing a new prescription. But sometimes they skip that step, or patients don't even remember what other drugs they're taking. In some cases it's possible to query the patient's current medication list from a service like Surescripts but even that won't necessarily be complete and some level of manual reconciliation is still needed. The other issue with drug interaction warnings is alert fatigue. For certain drugs there are a lot of known interactions, but those are considered minor acceptable risks due to lack of a better alternative. So clinicians get into a habit of ignoring all warnings and miss the ones that are actually serious. From a UX perspective there's no good way to solve this problem in a way that satisfies both the clinicians and the lawyers.

    Alert fatigue is real and sets in quickly -
