Please help with the these questions, I have the main idea but just need a bit more insight? 1. A common argument against outcomes research is it limits health care. Explain why someone making this argument needs to be more specific. 2. Outcomes research is full of problematic theoretical issues. Explain how even the simplest evaluation method, cost identification analysis, is subjective and the use of this method can result in different outcomes for the same treatment among different studies....
