In gripping accounts of true cases, surgeon Atul Gawande explores the power and the limits of medicine, offering an unflinching view from the scalpel’s edge. Complications lays bare a science not in its idealized form but as it actually is—uncertain, perplexing, and profoundly human.
Mountains Beyond Mountains takes us from Harvard to Haiti, Peru, Cuba, and Russia as Farmer changes minds and practices through his dedication to the philosophy that "the only real nation is humanity" - a philosophy that is embodied in the small public charity he founded, Partners In Health. He enlists the help of the GatesFoundation, George Soros, the U.N.’s World Health Organization, and others in his quest to cure the world. At the heart of this book is the example of a life based on hope, and on an understanding of the truth of the Haitian proverb “Beyond mountains there are mountains”: as you solve one problem, another problem presents itself, and so you go on and try to solve that one too.
Blood-and-guts accounts of Fallujah are not in short supply, but Jadick—a career Marine officer and brigade surgeon who took a demotion to battalion surgeon to volunteer for service in Iraq in 2004—tells the story through the eyes of a doctor. Unlike colleagues who remained in battalion aid stations behind the lines, Jadick and his medics accompanied their unit in makeshift ambulances as it battled through the streets. This was not bravado, he writes, but a calculated strategy to reach, stabilize and rush wounded troops to hospitals more quickly. He makes his case many times over, with dramatic accounts of catastrophically injured men from his unit and others who would not have survived a journey to the aid station. This remarkable man's story is well worth telling, although his writer should have discouraged him from frequent pauses for memorial essays on every soldier who died, and to remind readers of the Marines' bravery, of the dedication of the medics, and how much he loves his wife, the Marines and America. Readers who can skim past these segments will find the book a memorable experience. 
Jerome Groopman pinpoints the forces and thought processes behind the decisions doctors make. He explores why doctors err and shows when and how they can, with our help, avoid snap judgments, embrace uncertainty, communicate effectively, and deploy other skills that can have a profound impact on our health.
In this stunning new book, Malcolm Gladwell takes us on an intellectual journey through the world of "outliers"--the best and the brightest, the most famous and the most successful. He asks the question: what makes high-achievers different? His answer is that we pay too much attention to what successful people are like, and too little attention to where they are from: that is, their culture, their family, their generation, and the idiosyncratic experiences of their upbringing. Along the way he explains the secrets of software billionaires, what it takes to be a great soccer player, why Asians are good at math, and what made the Beatles the greatest rock band. Brilliant and entertaining, OUTLIERS is a landmark work that will simultaneously delight and illuminate. 
In this best-seller, a staff writer for The New Yorker weighs the factors that determine good decision-making. Drawing on recent cognitive research, Gladwell concludes that those who quickly filter out extraneous information generally make better decisions than those who discount their first impressions.
The other day I talked to a RN who planned on becoming a PA. He went to Pacific Lutheran University in Washington where the PA program suffered and died while he attended school there. After graduating with a bachelors in Biology he contemplated medical school and applied and while he was waiting he found a 3 month EMT certification program, he loved his job and was offered a position with the hospital where they paid for him to to become an RN and he's been there for 15 years. He told me he was glad he was working where he was it fit his life style, he leaves work at work, no malpractice insurance, good benefits, works as little or as much as he wants, he has a lot more patient contact then the doctors do and that is what brings him satisfaction with his job.
Anesthesiologist go to medical school and then take an additional 4 years of residency training followed by 1-4 more years of internship. Anesthesiologists determine whether someone is fit for anesthesia and then monitors them so the surgeon can focus solely on the operation. Anesthesiologists also have the choice to become pain specialists which is a rapidly growing and much needed field. Anesthesiologist typically have extraordinary math and memorization skills. They preform complex calculations on the fly to adjust drug dosages/rates and they must know how and when to safely use the millions of drugs at their disposal.
