If you think of any type of healthcare, you will find multiple providers offering similar services. But similar services never equate to similar healthcare outcomes.
Some healthcare providers will have enhanced capacity and better outcomes. Others will seemingly appear to be of equivalent capacity, but with awfully poor medical outcomes for their patients. How can you judge who provides healthcare of superior quality? This is never an easy task. Perceptions can easily be swayed by unregulated advertising, false representations of superiority, and even faked testimonials.
