Mahelen,
Taking a prompt and understanding in depth the question that you need to answer with your essay is essential. Based on the first sentence, the theme of this prompt seems to be the importance of quality care. How would you define quality care? Why does it matter? The second sentence seems to go in a different direction. Why is that sentence there? Is it suggesting that a central feature to quality care is not having the doctor as the final decision maker? Is it suggesting that one way to structure the essay is to compare and contrast between current standards of quality care and previous standards of quality care? Exploring the prompt with questions like this is a beginning point in developing a thesis, or focal point, to your essay. Do you have other questions? I suggest making notes, either actual note cards or a software tool that allows jotting down ideas and being to move them around.
Essays always require a thesis and supporting arguments. Supporting arguments are the facts/ideas that illustrate your thesis. I would start with defining the term "other dimensions of quality care." Can you make a list of at least three dimensions of quality care - state them, define them, provide examples, do research and provide citations of their importance. This will provide the body of your essay. Also, that word 'other' is suggesting a contrast to something. I am unclear from the prompt what the contrast is about? My guess is that it is referring to the provision of quality medical procedures and that 'quality care' refers to the extra parts of quality care.
The prompt may seem simple at first. I hoping this is an example of the exploratory thinking and initial note generation that will lead to a well-focused essay.
