The document discusses drug information centers (DICs), which provide unbiased drug information to healthcare professionals. DICs were first established in the 1960s and are usually located in major hospitals and health facilities. They are staffed by pharmacists with specialized training who locate, evaluate, and communicate drug information to answer questions from other healthcare providers. DICs aim to promote evidence-based practice and rational drug use through services like answering drug-related queries, publishing bulletins, and educating students.
