Medical mistakes are more pervasive than we think. How can we improve outcomes? An acclaimed MD's rich stories and research explore patient safety. Patients enter the medical system with faith that they will receive the best care possible, so when things go wrong, it's a profound and painful breach. Medical science has made enormous strides in decreasing mortality and suffering, but still, treatment can also cause harm - a significant portion of which is preventable. Drawing on current research, professional experience, and extensive interviews with nurses, physicians, administrators, researchers, patients, and families, physician and acclaimed author Danielle Ofri explores the diagnostic, systemic, and cognitive causes of medical error. Throughout, she illustrates her points via the powerfully human stories she's known for. Now, Dr. Ofri places the issues of medical error and patient safety front and center in our national healthcare conversation.
