Along with basic and clinical sciences, health systems science has become a crucial “third pillar” of medical education, with an emphasis on understanding the role of human factors, systems thinking, leadership, and health system improvement strategies that will help transform the future of health care and ensure greater patient safety. Health Systems Science, now in its 3rd Edition, was the first textbook devoted to this increasingly important branch of health care education, providing up-to-date, easy-to-understand coverage of how health care is delivered, how health care professionals work together to deliver that care, and how the health system can improve patient care and health care delivery. This fully revised edition addresses today’s key issues in the field, helping you acquire the knowledge and skills you need for success in today’s challenging health care system.
