The book “Defining the Value of Spine Care” discuses the concepts of value-based spinal care to the spine care provider. The spinal care coverage and payment are linked increasingly to the value of care. Hence the spine care provider can easily understand the concepts of value in the context of spinal care, outcome measures and cost measures. Initial chapters provide detail information on understanding the value of spine care and definition of common terminology. This is followed by the use of process measures in measuring the quality of spine care and disease-specific health-related quality of life measures in lumbar degenerative disease and cervical degenerative disease. It also discusses the numerical rating scales, the quality-adjusted life year, decision tree analysis and simulation modeling in spine care, etc. The last few chapters explain about value-based evaluation of new spine-related technology, determining value with outcome measures in perspectives from each of the stakeholders of spine care delivery, developing value-based guidelines for the treatment of spinal disorders and comparative effectiveness research in spine care using SPORT. Spine care providers need to measure the quality and value of the treatment and provide tools necessary for understanding the task.
