“Delivering Health Care in America: A Systems Approach,” 7ᵗʰ Edition, by Leiyu Shi and Douglas A. Singh, is a comprehensive textbook offering a structured, systems‑based overview of the U.S. health care system. It starts with historical evolution and cultural values, then examines core components—health professionals, medical technology, financing, care delivery settings (e.g. outpatient, inpatient, long‑term care), managed care, and care for special populations. Using updated data (e.g. on pandemics, chronic disease, Healthy People 2020), it explores cost, access, and quality challenges and recent reforms under the Affordable Care Act, including the roles of ACOs, medical homes, Medicaid and CO‑OPs. The final chapters consider health policy, workforce shortages, and future directions in U.S. health services delivery .
