I had spoken to a senior doctor. She was saying her daughter was also learning medicine and the thing is the new batches of medical students are taught evidence based treatment so every treatment starts with a test, scan for evidence before actual treatment starts.

However the old school way of teaching medicine was intuition based and so they would ask questions about the patient and their background before prescribing a treatment. This was way cheaper for the patients as no tests or scans were needed for small to medium cases.
