In addition to hospital costs, drug prices are also affected by supply and demand, patent protection, government regulations and so on. Drug manufacturers can control market supply through patent protection and other means, thus raising prices; Government regulations may also interfere with and adjust drug prices, thus affecting drug prices.
In addition, the cost of medical services is not only the cost of drugs, but also the use cost of medical equipment, the salaries of doctors and nurses, the operating costs of hospitals and other expenses. Therefore, although the price of hospital drugs is zero, the proportion in the whole medical service is not very large, and hospitals need to ensure the quality and safety of medical services through these expenses.
In short, the price of hospital drugs is affected by many aspects, and the cost of medical services is not only the cost of drugs, so although there is no price difference, the price of hospital drugs may still be higher.
