Ethics in Hospitals: Is this asking for too much?

Chennai Hospitals are popular world over with people from all over India and the world coming here to get treated in different illnesses. Hospitals however go to any extent to make lucrative deals out of their existing client base (patients)! I have heard stories in these lines but I heard someone very close to me go though a harrowing experience in one of the leading hospitals in Chennai.

The patient was asked to take a scan that was outdated in the first place. Second the patient had already taken a similar scan just a month back. The doctor refused to proceed with the operation if this was not done. I could think of only one possible reason as to why this was advised. Any scanning device would have cost the hospital several thousand rupees and the doctor has to ensure that the hospital gets the ROI quickly. Maybe they are even ranked on this basis. Amazing right!!. This is just the start of the problem. Based on the results of the scan, more tests and procedures could be advised that were totally unnecessary. Luckily we had 2 other family doctors who were able to identify and tell us that this was unnecessary

All I could think was imagine the lakhs of underprivileged people who consider doctors as Gods, They trust them totally and believe that every step the doctor takes is most necessary. Do they have any way of even finding this out? When they are hardly able to afford just one doctor where is the question of asking for a second opinion? I am not saying doctors should do social service. After all it’s a profession for them too. But they can realize that in their case however they are dealing with lives of people and that deserves a little more care.
