When we have questions or suggestions about a drug-drug interaction severity level rating, we share this with First DataBank, the drug information vendor for our homegrown EHR. A pharmacist from FDB typically responds to our emails within 2 weeks. They don't often make a change based on our emails, but they at least acknowledge our concern and explain their rationale.
In contrast, the drug information vendor servicing our pharmacy platform, MediSpan, has not yet responded to the few drug-drug interaction rating queries we've sent.
What has been your experience in debating drug-drug interaction ratings with your EHR's or pharmacy platform's drug information vendors? Are you usually given a direct contact, or do you have to send queries through your health system's IT staff?
