How do doctors communicate with each other when treating the same patient of different ailments in order to avoid interactions?

Doctors often communicate through electronic health records (EHRs), which provide a centralized platform for sharing patient information, including medications and treatment plans. They may also hold case discussions in multidisciplinary team meetings or consult with each other directly via phone or secure messaging. Clear documentation and regular updates ensure that all healthcare providers involved in a patient's care are aware of each other's actions, helping to prevent potential drug interactions and coordinating treatment effectively.
