Burden of tests and costly drugs on poor patients

Bangladesh is a densely populated country. Majority people belong to the low income group. More than 30 percent of the population are ultra-poor, while more than 60 percent of them live on the poverty line. Access to modern medical facilities is merely a dream for them. But most of the doctors advise a lot of tests and of prescribe costly medicines.
It seems that they (the doctors) do not bother about the financial capacity of the poor patients. They should avoid advising unnecessary tests and should also consider the price of medicine before prescribing for patients. We know that there are different prices for the same medicine produced by different pharmaceutical companies. Only sensible advice and prescription by doctors can save the plight of the poor people.
