A scientific study of nature that sometimes includes processes involved in health and disease. For example, clinical trials are research studies that involve people. These studies may be related to new ways to screen, prevent, diagnose, and treat disease. They may also study certain outcomes and certain groups of people by looking at data collected in the past or future.

If the element is present, it must have either a @value, an @id, or extensions Canonical identifier for this study resource, represented as a globally unique URI. Identifiers assigned to this research study by the sponsor or other systems. The business version for the study record. Name for this study (computer friendly). The human readable name of the research study. Additional names for the study. The set of steps expected to be performed as part of the execution of the study. A larger research study of which this particular study is a component or step. Citations, references, URLs and other related documents. When using relatedArtifact to share URLs, the relatedArtifact.type will often be set to one of "documentation" or "supported-with" and the URL value will often be in relatedArtifact.document.url but another possible location is relatedArtifact.resource when it is a canonical URL. The date (and optionally time) when the ResearchStudy Resource was last significantly changed. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the ResearchStudy Resource changes. The publication state of the resource (not of the study). The type of study based upon the intent of the study activities. A classification of the intent of the study. The stage in the progression of a therapy from initial experimental use in humans in clinical trials to post-market evaluation. Codes categorizing the type of study such as investigational vs. observational, type of blinding, type of randomization, safety vs. efficacy, etc. The medication(s), food(s), therapy(ies), device(s) or other concerns or interventions that the study is seeking to gain more information about. The condition that is the focus of the study. For example, In a study to examine risk factors for Lupus, might have as an inclusion criterion "healthy volunteer", but the target condition code would be a Lupus SNOMED code. Key terms to aid in searching for or filtering the study. A country, state or other area where the study is taking place rather than its precise geographic location or address. A brief text for explaining the study. A detailed and human-readable narrative of the study. E.g., study abstract. Identifies the start date and the expected (or actual, depending on status) end date for the study. A facility in which study activities are conducted. Comments made about the study by the performer, subject or other participants. Additional grouping mechanism or categorization of a research study. Example: FDA regulated device, FDA regulated drug, MPG Paragraph 23b (a German legal requirement), IRB-exempt, etc. Implementation Note: do not use the classifier element to support existing semantics that are already supported thru explicit elements in the resource. Sponsors, collaborators, and other parties. Status of study with time for that status. A description and/or code explaining the premature termination of the study. Target or actual group of participants enrolled in study. Describes an expected event or sequence of events for one of the subjects of a study. E.g. for a living subject: exposure to drug A, wash-out, exposure to drug B, wash-out, follow-up. E.g. for a stability study: {store sample from lot A at 25 degrees for 1 month}, {store sample from lot A at 40 degrees for 1 month}. A goal that the study is aiming to achieve in terms of a scientific question to be answered by the analysis of data collected during the study. An "outcome measure", "endpoint", "effect measure" or "measure of effect" is a specific measurement or observation used to quantify the effect of experimental variables on the participants in a study, or for observational studies, to describe patterns of diseases or traits or associations with exposures, risk factors or treatment.
