Our simple definition of ethics is good thought, speak and action. Epistemology means the hypothesis of facts about thought, speech and action. Medical practice is all means of medicine.
Medicine classifies people into normal and abnormal. The abnormal are the sick. They loose some organs or those normal looking organs are dysfunctional. They are social problems, some can be treated, and some do not get the appropriate care.
The problems of society of normal people are overeating and obesity, abortion, drug abuse, promiscuity, torture, terrorism, disobeying rules and order, corruption, brain-washing and unethical advertisements, etc.
On the other hand, the social problems of the abnormal are down, deafness, blindness, dumb, hypertension, hypercholesterolemia, diabetes mellitus and cancer, etc.
An example of the social-doctor problem is the mal distribution of doctors in rural areas. It was reported by the ministry of public health that the ratio of doctor to population to be 1:800 in Bangkok and 1:5,700 in some rural areas in the north eastern part of Thailand(2). The doctors, themselves, are at a high grade of worker and intelligent quotient. They know all the problem and, at the same time, create problems, both, faster than the general population can do. It affects good and bad in the society. In the past, present and the foreseeable future the medical students get their studies in the western style. Their medical schools are situated in big cities. These schools are old and famous. They learn their medical procedure in a big hospital of more than 400 beds in the inpatient department wards.
Their instructors and professors are highly qualified, are middle class people and well accepted in the society. Their families are lovely and warm. Their children study in the first class schools in town. The medical students feel very happy and appreciate seeing their professors in television routinely at prime time.
In conclusion, their professors are an example of role model for them to follow. Everyone looks for security in her/his profession. Facts need no proof and reference. People with justice in mind should believe and understand the above mentioned. This leads to the problem of mal distribution of doctors in rural areas, why do doctors live in big cities or wish to be in the private sector?
In fact, not many a number of doctors serve in the rural area. About 4-5 of them, their name will be announced yearly as the best rural doctor award. After the big ceremony, lasted not longer than a month, it is hard to remember their name. They are proud to be praised, it pushes them into stress intentionally with all the best of their intelligence and the total of their body strength to work harder in rural. Unfortunately their earning, the security of their profession, the increased chance of being sued, to get caught in the medical litigation, the expenses of their family social status and the study of their children cannot be compared to of those doctors in big city and/or in the private sector.
Mal distribution of doctors in remote rural areas has been a persisting unresolved problem in many parts of the world, why not apply the principles of ethics and epistemology? They have been left, untouched forever.
