The health industry has grown exponentially to a very basic reason. The more it grows the better are the healthcare facilities in a country and the better is the healthcare facilities the more is the life expectancy of the people in that region. A higher expectancy of life simply means that there are more elderly people in a country i.e. there are more people to take care of. Hence healthcare training programs become very important.
Even more than doctors there is a bulk requirement for limitedly trained nurses. This is due the fact that the bulk of the care taking of the patients is undertaken by the nurses. Doctors can not take up the day to day services of the patient and these are taken up by the nurses. This has led to a demand for licensed vocational nurses.
