Comparative effectiveness research (CER)—the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition or to improve the delivery of care. The purpose of CER is to assist consumers, clinicians, purchasers, and policy makers to make informed decisions that will improve health care at both the individual and the population level (IOM, 2009b)
Conflict of interest—a set of circumstances that creates a risk that professional judgment or actions regarding a primary interest will be unduly influenced by a secondary interest (IOM, 2009c)
Cost-effectiveness—a formal method for comparing the benefits of a medical intervention (measured in terms of clinical outcome or utility) with the costs of the medical intervention to determine which alternative provides the maximum aggregate health benefits for a given level of resources, or equivalently, which alternative provides a given level of health benefits at the lowest cost (Sloan, 1996)

Some decision aids are targeted at patients, and others are targeted for clinician use with patients (MedPAC, 2010)
Demonstration project—a project, supported through a grant or a cooperative agreement, generally to establish or demonstrate the feasibility of new methods or new types of services (NCI, 2013c)
Diagnosis—the process of identifying a disease, such as cancer, from its signs and symptoms (NCI, 2012)
Direct care workers—providers of paid hands-on care, supervision, and emotional support for patients. They are typically categorized as nurse aids or nursing assistants, home health aides, and personal and home care aides. They most often provide care in a patient’s home, a nursing home, or a hospital (IOM, 2008b)

Learning health care information technology (IT) system—a health care system that uses advances in information technology to continuously and automatically collect and compile the evidence needed to deliver the best, most up-to-date personalized care for each patient from clinical practice, disease registries, clinical trials, and other information sources. That evidence is made available as rapidly as possible to users of a [learning health care IT system], which include patients, physicians, academic institutions, hospitals, insurers, and public health agencies. A [learning health care IT system] ensures that this data-rich system learns routinely and iteratively by analyzing captured data, generating evidence, and implementing new insights into subsequent care (IOM, 2010 [adapted from Etheredge, 2007])

Palliative care—patient- and family-centered care that optimizes quality of life by anticipating, preventing, and treating suffering. Palliative care throughout the continuum of illness involves addressing physical, intellectual, emotional, social, and spiritual needs and facilitating patient autonomy, access to information, and choice (NQF, 2006)
Patent—an exclusive right to the benefits of an invention or improvement granted by the U.S. Patent Office, for a specific period of time, on the basis that it is novel (not previously known or described in a publication), “nonobvious” (a form which anyone in the field of expertise could identify), and useful (The Free Dictionary, 2013)
Patient-centered care—providing care that is respectful of and responsive to individual patient, needs, values, and preferences and ensuring that patient values guide all clinical decisions (IOM, 2001)
Patient-centered communication—processes and outcomes of the patient-clinician interaction that elicit, understand, and validate the patient’s perspective (e.g., concerns, feelings, expectations); understand the patient within his or her own psychological and social context; reach a shared understanding of the patient’s problem and its treatment; help a patient share power by offering him or her meaningful involvement in choices relating to his or her health; build a stronger patient-clinician relationship characterized by mutual trust, respect, and commitment; and enhance the patient’s well-being to reduce suffering after the patient leaves the consultation (adapted from Epstein and Street, 2007)
Patient-clinician interactions—the communication, shared decision making, and provision of care that occurs between patients and their care teams (see Chapter 3)

Prognosis—the likely outcome or course of a disease; the chance of recovery or recurrence (NCI, 2012)
Psychosocial health services—psychological and social services and interventions that enable patients, their families, and health care providers to optimize biomedical health care and to manage the psychological/ behavioral and social aspects of illness and its consequences so as to promote better health (IOM, 2008a)
Quality measure or metric—quantitative indicators that reflect the degree to which care is consistent with the best available, evidence-based clinical standards (IOM, 2005)
Quality of care—the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge (IOM, 1990)
Quality of life—the overall enjoyment of life. Many clinical trials assess the effects of cancer and its treatment on the quality of life. These studies measure aspects of an individual’s sense of well-being and ability to carry out various activities (IOM and NRC, 2005)
Radiation therapy—the use of high-energy radiation from X-rays, gamma rays, neutrons, and other sources to kill cancer cells and shrink tumors.
Radiation may come from a machine outside of the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy, implant radiation, or brachytherapy). Systemic radiotherapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that circulates throughout the body, also called radiation therapy (NCI, 2012)
Randomized clinical trial—a study in which the participants are assigned by chance to separate groups that compare different treatments; neither the researchers nor the participants can choose the group to which they are assigned. Using chance to assign people to groups means that the groups will be similar and the treatments they receive will be compared objectively. At the time of the trial, it is not known which treatment is best. It is the patient’s choice to be in a randomized trial (NCI, 2012)
Recurrence—cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body (NCI, 2012)
Remission—a decrease in or disappearance of signs and symptoms of cancer. In partial remission, some, but not all, signs and symptoms of cancer have disappeared. In complete remission, all signs and symptoms of cancer have disappeared, although cancer may still be in the body (NCI, 2012)
Shared decision making—the process of negotiation by which physicians and patients arrive at a specific course of action, based on a common understanding of the goals of treatment, the risks and benefits of the chosen treatment versus reasonable alternatives, and the patient’s needs, values, and preferences (adapted from IOM, 2011d)
Staging—performing exams and tests to learn the extent of the cancer within the body, especially whether the disease has spread from the original site to other parts of the body. It is important to know the stage of the disease in order to plan the best treatment (NCI, 2012)
Survivor—an individual is considered a cancer survivor from the time of cancer diagnosis through the balance of his or her life, according to the National Coalition for Cancer Survivorship and the NCI Office of Cancer Survivorship. Family members, friends, and caregivers are also impacted by the survivorship experience and are therefore included in this definition (IOM and NRC, 2005)
Survivorship care—a distinct phase of care for cancer survivors that includes four components: (1) prevention and detection of new cancers and recurrent cancer; (2) surveillance for cancer spread, recurrence, or second cancers; (3) intervention for consequences of cancer and its treatment; and (4) coordination between specialists and primary care providers to ensure that all of the survivor’s health needs are met (IOM and NRC, 2005)
Survivorship research—encompasses the physical, psychosocial, and economic sequelae of cancer diagnosis and its treatment among both pediatric and adult survivors of cancer. It also includes within its domain issues related to health care delivery, access, and follow-up care as they relate to survivors. Survivorship research focuses on the health and life of a person with a history of cancer beyond the acute diagnosis and treatment phase. It seeks both to prevent and to control adverse cancer diagnosis and treatment-related outcomes, such as late effects of treatment, second cancers, and poor quality of life; to provide a knowledge base regarding optimal follow-up care and surveillance of cancers; and to optimize health after cancer treatment (IOM and NRC, 2005)
Systematic review—a scientific investigation that focuses on a specific question and uses explicit, planned scientific methods to identify, select, assess, and summarize the findings of similar but separate studies. It may or may not include a quantitative synthesis of the results from separate studies (meta-analysis) (IOM, 2011b)
Team-based care—the provision of health services to individuals, families, and/or their communities by at least two health care clinicians who work collaboratively with patients and their caregivers—to the extent preferred by each patient—in order to accomplish shared goals within and across settings to achieve coordinated, high-quality care (Mitchell et al., 2012)
Total cost—the direct medical costs resulting from the provision of cancer care (see Chapter 3)
Toxicity—a measure of the degree to which something is toxic or poisonous (IOM and NRC, 2005)
Value-based insurance design (VBID)—a benefit design that is intended to encourage patients to choose beneficial treatments and forgo treatments with little or no benefit. High-quality cancer interventions would be available at little or no out-of-pocket costs to patients, and interventions that
are of questionable benefit to patients would require more cost sharing (IOM, 2009a)
Value-based purchasing (VBP)—links provider payments to improved performance by health care providers. This form of payment holds health care clinicians accountable for both the cost and the quality of care they provide. VBP attempts to reduce inappropriate care and to identify and reward the best-performing providers (HealthCare.gov, 2013a)
Values—a patient’s concerns, expectations, and choices regarding health care, based on a full and accurate understanding of care options (adapted from IOM, 2001, 2003)
Vulnerable and underserved—people who may have difficulty accessing high-quality cancer care, including but not limited to racial and ethnic minorities, older adults, individuals living in rural and urban underserved areas, uninsured and underinsured individuals, and populations of lower socioeconomic status (see Chapter 8)
