What is a best possible medication history?

A best possible medication history (BPMH) is a list of medications (prescribed and non-prescribed) that a patient is currently taking. The BPMH can be created from interviewing the patient/family; as well as reviewing at least one other reliable source of information (often, a patient’s pharmacy). Complete documentation, including drug name, dosage, route, and frequency is needed. The BPMH can then be used in the hospital to help physicians decide which medications to add, change, or discontinue.
