When you think about patients and their health issues, you tend to take one of two approaches: you either focus on things more granularly or you look at the bigger picture. Let's call this micro vs macro. Macro issues might include what connects the larger patient population to issues around a particular disease. Macro looks at statistics and demographics of a patient population. But when you think about patients on a micro level, you get an understanding of how specific patients deal with the everyday realities of living with an illness.
