?This book investigates the impact of patient-centered care (PCC) for older adults with chronic conditions and presents new evidence concerning its effects on the care process and health outcomes. The book highlights the impact of PCC on elderly chronic disease patients’ health experiences and demonstrates that PCC is associated with better performance in delivering care to this group of patients. The PCC approach also provides opportunities for improving the delivery of cancer care, although patient-centered oncology care is still in its infancy and evidence on its effectiveness is scant. The book also includes a systemic review and meta-analysis of connections between PCC and cancer patients’ adverse healthcare utilization, costs, patient satisfaction, and quality of care. This book is unique in terms of the measures’ comprehensiveness and provides ample evidence that the implementation of PCC is associated with better healthcare performance. The intended readers include researchers in related fields, graduate students, and healthcare providers. It is hoped the book offers further evidence for meaningful practice and have many policy and research implications in PCC.
