Reshaping Health Systems: What Drives Health Care and How You Can Change It illuminates how forces in the health care system ("systems factors") impact patient care before outlining strategies ("systems solutions") to enact change and improve care delivery. Using a case-based format that mirrors real-world scenarios involving patients and clinicians, Drs. Liao, Staloff, and Joo impart foundational health systems knowledge and skills in ways that are intuitive, enjoyable, and accessible for clinicians and health system leaders alike. The book is divided into two parts. Part I follows the journey of a patient navigating systems factors that influence her care across care settings. Part II follows the journey of a clinician working to improve care delivery using systems solutions from fields such as quality improvement, design thinking, change management, and implementation science. Together, the book provides foundational and actionable training in health systems for a wide range of clinical and non-clinical team members and leaders in health care. Readers will not only understand how our health care system works; they will be equipped to improve it.
