Adverse events
Undesirable experiences associated with medical care, such as a surgical site infection or other postoperative complications, serious morbidity, or death. The goal is to minimize or eliminate such events.
Behavioral risk factors for disease
Individual behaviors such as smoking, lack of exercise, poor dietary choices and overconsumption of alcohol that have a negative impact on health and lead to chronic disease.
Big data
Big data is a term with uncertain roots, and variable usage, but one that paints a picture of extremely large amounts of information, complex and disparate, that is difficult to analyze using traditional tools. Big data is being used more and more frequently by health science researchers to delve into many of the questions in health care today.
Chronic medical and psychiatric disease
Chronic diseases, such as diabetes, heart disease and arthritis, that persist over time and require consistent efforts to keep the disease from progressing or causing significant declines in quality of life. Psychiatric diseases, often referred to as mental illnesses, affect mood, thinking processes, the ability to relate to others or daily functioning.
Clinical engagement
Involving clinicians in collaborative research efforts to understand clinically relevant information and utilize their expertise to guide research studies in ways that have practice-changing implications. This involvement includes developing the research question, defining the cohort using clinically relevant information, and identifying who or what is the best channel to inform practice at large of the applicable findings.
Clinical informatics
The study and pursuit of effective use of biomedical data, information and knowledge for the purpose of improving health.

Health sciences research (also known as health services research)
As defined in the February 2002 issue of Health Services Research, health sciences research is the multidisciplinary field of scientific investigation that studies how social factors, financing systems, organizational structures and processes, health technologies, and personal behaviors affect access to health care, the quality and cost of health care, and ultimately health and well-being. Its research domains are individuals, families, organizations, institutions, communities and populations.

A collaborative network of more than 75 community-based practices funded as part of the Department of Health and Human Services Transforming Clinical Practice Initiative. The network supports more than 1,200 clinicians as they expand their quality improvement capacity, learn from one another, and achieve common goals of improved care, better health and reduced cost. It provides technical assistance related to integrated behavioral health, readmissions, chronic disease management, medication therapy management, shared decision-making and management of patients with complex medical issues, including multiple chronic conditions.
Mayo value proposition
Mayo Clinic measures the value of care provided to patients in terms of both quality (patient outcomes, patient satisfaction and patient safety) and cost over time. The goal is to strive for the highest quality care while reducing costs.
The statistical combination of two or more separate studies.
Observational studies
Studies in which the individuals (or other units) are allocated to different interventions using methods that are not random.
Operations research
A scientific approach that is part of systems engineering using mathematical tools such as optimization, simulation and queuing theory to solve complex problems.
OptumLabs is a research alliance co-founded in 2012 by Optum Inc. and Mayo Clinic that combines vast amounts of clinical data, claims data and other consumer data in a shared data resource. In addition, it provides a research environment, including technology, tools, collaboration space and operating processes, and a translation network (to assist in moving knowledge to practice and policy change). As of fall 2015, the collaboration had expanded to include 21 partners.
Outcomes research
Outcomes research studies the end results of medical care — the effect of the health care process on the health and well-being of patients and populations.
Patient-Centered Network of Learning Health Systems (LHSNet)
A patient-centered network of nine learning health systems established in 2015 with funding from the Patient-Centered Outcomes Research Institute. This clinical data research network serves approximately 10 million patients across 10 states and is building an infrastructure to facilitate patient-centered outcomes research; support large pragmatic clinical trials as well as observational and interventional comparative effectiveness research studies embedded within the health care systems; and enable the dissemination, implementation, and evaluation of clinical and community efforts to improve population health.
Patient-reported outcome (PRO)
A PRO is any report of the status of a patient's health condition (for example, symptoms or functional status), health behavior, or experience with health care or the health care system that comes directly from the patient without interpretation by a clinician or anyone else.
Point-of-care system
Tools (often electronic) used by a patient care provider during an encounter with a patient to document the visit, enter notes, order tests, schedule visits, and so on, for that patient.
Predictive analytics
A research method that finds relationships in data that can be used to predict future probabilities and trends.

Study in which the individuals (or other units) followed were definitely or possibly assigned prospectively to one of two (or more) alternative forms of health care using random allocation (by chance alone).
Rochester Epidemiology Project (REP)
A research infrastructure system that links together nearly all of the medical records of the residents of Olmsted County, Minnesota, for approved medical research. This infrastructure makes it possible to conduct population-based descriptive, case-control, historical and prospective cohort, and cross-sectional research studies of most diseases and medical conditions.
Retrospective analyses
Analysis of existing data to explore factors that led to a particular outcome.
Science of health care delivery
A multidisciplinary approach to address the problems in health care by focusing on the way patients actually receive care. From using engineering principles to determine the most efficient way to schedule patient appointments to research focusing on the most successful, cost-effective means for delivering treatment, this discipline's aim is to enhance the patient's experience with health care by improving quality, outcomes and cost.
Shared decision-making
Clinicians and patients use the best available evidence when faced with the task of making decisions. Patients are supported to deliberate about the possible attributes and consequences of options and arrive at informed preferences in determining the best action. This approach respects patient autonomy and is ethical and legal.
Social determinants of disease
Social determinants of disease include factors in the physical (such as places to exercise and access to health care) and social (such as social support and meaningful connections) environment that influence health outcomes.
How a human interacts with a technology (for example, with a computer).
Stepped wedge cluster randomized trial
A type of randomized controlled trial in which randomization occurs at the group level rather than the individual level and the intervention is sequentially rolled out to groups over time.
Surgical outcomes
The study of the quality of surgical care and experience of patients after their surgery is completed, such as the complications they might experience (such as infection), whether they are discharged to their home or another facility, and survival rates following the procedure.

Systems engineering
An engineering approach to solve problems involving the entirety of a complex system (from the beginning to the end of a care process).
Translational research
An integral part of biomedical research that translates laboratory findings to clinical practice and vice versa — from clinical observations back to the laboratory for further testing, providing better services to patients and providers based on clinical and biological data. Also called "bench to bedside and back."
