In addition to the issue of hospital costs, the price of drugs is also affected by supply and demand, patent protection, government regulations and other aspects. Drug manufacturers can control market supply through patent protection and other means, thus raising prices; government regulations may also intervene and adjust drug prices, thus affecting drug prices.
In addition, the cost of medical services is not only the cost of medicines, but also includes the cost of using medical equipment, the salaries of doctors and nurses, the operating costs of hospitals, and other aspects of the cost. Therefore, although the price of drugs in hospitals is 0 differential, it does not account for a very large proportion of the overall medical services, and hospitals need to ensure the quality and safety of medical services through these costs.
In short, the price of hospital drugs is affected by a variety of aspects, and the cost of health care services is not only the cost of drugs, so the price of hospital drugs, although the price of 0 difference, but still may be higher.
