What is the author's style in Complications: A Surgeon's Notes on an Imperfect Science by Atul Gawande?

Since it is based on real experiences, the retelling of stories, particularly of patients, the book requires some third person narrative. Since the book is rooted in the uncertainties of medical practice, the third person voice is never completely omniscient—just as knowledgeable as a human being in the situation would be.

Dialogue is infrequently used and the stories are told mostly through description. The characters are typically limited to only one chapter, therefore exposition in the third person narrative is used to create sufficient development and backstory.
