Malpractice rampant in medical sector

Recently, I went to a hospital in Dhanmondi with my father to see a well-known doctor. I saw a group of men in formal wear looking at patients' reports. They apparently work in pharmaceutical companies. They were there to check whether the doctors were prescribing medicine made by their companies.           

Nowadays, it's a common practice among the pharmaceutical companies to send their representatives to hospitals and provide the doctors with gifts and free samples of medicine so that the latter prescribe medicines made by their companies. In many cases, doctors prescribe medicine that is unnecessary and expensive. We urge the doctors not to be influenced by pharmaceutical companies.
