The Business Dictionary defines competition from an economics point of view as: rivalry in which every seller tries to get what other sellers are seeking at the same time: sales, profit, and market share by offering the best practicable combination of price, quality, and service. Where the market information flows freely, competition plays a regulatory function in balancing demand and supply.
The Merriam-Webster's Learner's Dictionary gives what it calls a simple Definition of competition: the act or process of trying to get or win something (such as a prize or a higher level of success) that someone else is also trying to get or win : the act or process of competing; actions that are done by people, companies, etc., that are competing against each other. The competition: a person or group that you are trying to succeed against : a person or group that you are competing with.
I would use the terms access, quality and price more instead of competition as far as public health and medicine go. Why? Because public health and medicine as services are different for each individual. Public health is a science of protecting and improving the health of families and communities through promotion of healthy lifestyles, research for disease and injury prevention and detection and control of infectious diseases. Overall, public health is concerned with protecting the health of entire populations. According to CDC. Public health is about protecting the safety and improving the health of communities through education, policy making and research for disease and injury prevention.
